Whenever the work of an influential philosopher is criticized, a common move made by those who seek to defend the influential philosopher’s work is to claim that his or her ideas have been misconstrued. This is an effective move, of course, for it means that the critics have criticized a straw man, not the ideas actually put forth by the influential philosopher. However, this move can easily backfire, too.

For continued iterations of this move could render the ideas in question immune to criticism in a rather ad hoc fashion. That is to say, shouting “straw man” every time an influential philosopher’s ideas are subjected to scrutiny is rather like shouting “wolf” when none is around; it could be seen as an attempt to draw attention to that which may not be worthy of attention.

The question, then, is whether the influential philosopher’s ideas are worthy of attention and/or acceptance. In particular, are Kuhn’s ideas about scientific revolutions and incommensurability worthy of acceptance? As I have argued, along with a few other contributors to my edited volume, The Kuhnian Image of Science: Time for a Decisive Transformation? (2018), they may not be because they are based on dubious assumptions and fallacious argumentation.

In their reviews of The Kuhnian Image of Science: Time for a Decisive Transformation? (2018), both Markus Arnold (2018) and Amanda Bryant (2018) complain that the contributors who criticize Kuhn’s theory of scientific change have misconstrued his philosophy of science and they praise those who seek to defend the Kuhnian image of science. In what follows, then, I would like to address their claims about misconstruing Kuhn’s theory of scientific change. But my focus here, as in the book, will be the evidence (or lack thereof) for the Kuhnian image of science. I will begin with Arnold’s review and then move on to Bryant’s review.

Arnold on the Evidence for the Kuhnian Image of Science

Arnold (2018, 42) states that “one of the results of [his] review” is that “the ‘inductive reasoning’ intended to refute Kuhn’s incommensurability thesis (found in the first part of the book) is actually its weakest part.” I am not sure what he means by that exactly. First, I am not sure in what sense inductive reasoning can be said to refute a thesis, given that inductive arguments are the sort of arguments whose premises do not necessitate the truth of their conclusions, whereas a refutation of p, if sound, supposedly shows that p must be false.

Second, contrary to what Arnold claims, I do not think that the chapters in Part I of the book contain “‘inductive reasoning’ intended to refute Kuhn’s incommensurability thesis” (Arnold 2018, 42). Speaking of my chapter in particular, Chapter 1 (Mizrahi 2018b, 32-38), it contains two arguments intended to show that there is no deductive support for the Kuhnian thesis of taxonomic incommensurability (Mizrahi 2018b, 32), and an argument intended to show that there is no inductive support for the Kuhnian thesis of taxonomic incommensurability (Mizrahi 2018b, 37).

These arguments are deductive, not inductive, for their premises, if true, guarantee the truth of their conclusions. Besides, to argue that there is no evidence for p is not the same as arguing that p is false. None of my arguments is intended to show that p (namely, the Kuhnian thesis of taxonomic incommensurability) is false.

Rather, my arguments show that there is no evidence for p (namely, the Kuhnian thesis of taxonomic incommensurability). For these reasons, as a criticism of Part I of the book, Arnold’s (2018, 42) claim that “the ‘inductive reasoning’ intended to refute Kuhn’s incommensurability thesis (found in the first part of the book) is actually its weakest part” completely misses the mark.

Moreover, the only thing I could find in Arnold’s review that could be construed as support for this claim is the aforementioned complaint about straw-manning Kuhn. As Arnold (2018, 43) puts it, “the counter-arguments under consideration brought forward against his model seem, paradoxically, to underestimate the complexity of Kuhn’s claims.”

In other words, Kuhn’s theory of scientific change is so complex and those who attempt to criticize it fail to appreciate its complexity. But why? Why do the criticisms fail to appreciate the complexity of Kuhn’s theory? How complex is it such that it defies interpretation and criticism? Arnold does not say. Instead, he (Arnold 2018, 43) states that “it is not clear, why Kuhn’s ‘image of science’ should be dismissed because […] taxonomic incommensurability ‘is the exception rather than the rule’ [Mizrahi 2018b,] (38).”

As I argue in Chapter 1, however, the fact that taxonomic incommensurability “is the exception rather than the rule” (Mizrahi 2018b, 38) means that Kuhn’s theory of scientific change is a bad theory because it shows that Kuhn’s theory has neither explanatory nor predictive power. A “theory” with no explanatory and/or predictive power is no theory at all (Mizrahi 2018b, 37-38). From his review, however, it is clear that Arnold thinks of Kuhn’s image of science as a theory of scientific change.

For instance, he talks about “Kuhn’s epistemology” (Arnold 2018, 45), “Kuhn’s theory of incommensurability” (Arnold 2018, 46), and Kuhn’s “complex theory of science” (Arnold 2018, 42). If Kuhn’s thesis of taxonomic incommensurability has no explanatory and/or predictive power, then it is a bad theory, perhaps not even a theory at all, let alone a general theory of scientific knowledge or scientific change.

In that respect, I found it rather curious that, on the one hand, Arnold approves of Alexandra Argamakova’s (2018) criticism of the universal ambitions of Kuhn’s image of science, but on the other hand, he wants to attribute to Kuhn the view that “scientific revolutions are rare” (Arnold 2018, 43). Arnold quotes with approval Argamakova’s (2018, 54) claim that “distinct breakthroughs in science can be marked as revolutions, but no universal system of criteria for such appraisal can be formulated in a normative philosophical manner” (emphasis added).

In other words, if Argamakova is right, then there can be no philosophical theory of scientific change in general, Kuhnian or otherwise. So Arnold cannot be in agreement with Argamakova without thereby abandoning the claim that Kuhn’s image of science is an “epistemology” (Arnold 2018, 45) of scientific knowledge or a “complex theory of science” (Arnold 2018, 42).

Arnold (2018, 45) also asserts that “the allegation that Kuhn developed his theory on the basis of selected historical cases is refuted” by Kindi (2018). Even if that were true, it would mean that Kuhn’s theory has no inductive support, as I argue in Chapter 1 of the book (Mizrahi 2018b, 32-38). So I am not sure how this point is supposed to help Arnold in defending the Kuhnian image of science. For if there is no inductive support for the Kuhnian image of science, as Arnold seems to think, and there is no deductive support either, as I (Mizrahi 2018b, 25-44) and Park (2018, 61-74) argue, then what evidence is there for the Kuhnian image of science?

For present purposes, the important point is not how Kuhn “developed his theory” (Arnold 2018, 45) but rather what supports his theory of scientific change. What is the evidence for a Kuhnian theory of scientific change? If I am right (Mizrahi 2018b), or if Park (2018) is right, then there is neither deductive support nor inductive support for a Kuhnian theory of scientific change. If Argamakova is right, then there can be no general theory of scientific change at all, Kuhnian or otherwise.

It is also important to note here that Arnold (2018, 45) praises both Kindi (2018) and Patton (2018) for offering “a close reading of Kuhn’s work,” but he does not mention that they offer incompatible interpretations of that work, specifically, of the evidence for Kuhn’s ideas about scientific change. On Kindi’s reading of Kuhn, the argument for the Kuhnian image of science is a deductive argument from first principles, whereas on Patton’s reading of Kuhn, the argument for the Kuhnian image of science is an inference to the best explanation (see Patton 2015, cf. Mizrahi 2018a, 12-13; Mizrahi 2015, 51-53).

Bryant on the Evidence for the Kuhnian Image of Science

Like Arnold, Bryant (2018, 1) wonders whether Kuhn’s views on scientific change can be pinned down and criticized or perhaps there are many “Thomases Kuhn.” Again, I think we do not want to make Kuhn’s views too vague and/or ambiguous (Argamakova 2018, 47-50), and thus immune to criticism in a rather ad hoc fashion. For that, in addition to being based on dubious assumptions and fallacious argumentation, would be another reason to think that Kuhn’s views are not worthy of acceptance.

Bryant (2018, 1) also wonders “whether the so-called Kuhnian image of science is really so broadly endorsed as to be the potential subject of (echoing Kuhn’s own phrase) a ‘decisive transformation’.” As I see it, however, the question is not whether the Kuhnian image of science is “broadly endorsed.” Rather, the question is whether “we are now possessed” by it. When Kuhn wrote that (in)famous first line of the introduction to The Structure of Scientific Revolutions, the image of science by which we were possessed was a positivist image of science according to which science develops “by the accumulation of individual discoveries and inventions” (Kuhn 1962/1996, 2). Arguably, philosophers of science were never possessed by such a positivist image of science as much as they are possessed by the Kuhnian image of science.

This is evidenced by the fact that no positivist work in philosophy of science has had as much impact as Kuhn’s seminal work (Mizrahi 2018a, 1-2). Accordingly, even if the Kuhnian image of science is not “broadly endorsed,” it is quite clear that philosophers of science are possessed by it. For this reason, an “exorcism,” or a “decisive transformation,” is required in order to rid ourselves of this image of science. And what better way to do so than by showing that it is based on dubious assumptions and fallacious argumentation.

As far as the evidence (or lack thereof) for the Kuhnian image of science, Bryant (2018, 2) claims that “Case studies can be interesting, informative, and evidential” (emphasis added). I grant that case studies can be interesting and informative, but I doubt that they can be evidential. From “Scientific episode E has property F,” it does not follow that F is a characteristic of scientific episodes in general. As far as Kuhn is concerned, it is clear that he used just a few case studies (e.g., the phlogiston case) in support of his ideas about scientific change and incommensurability.

The problem with that, as I argue in Chapter 1 of the book (Mizrahi 2018b, 32-38), is that no general theory of scientific change can be derived from a few cherry-picked case studies. Even if we grant that the phlogiston case is a genuine case of a so-called “Kuhnian revolution” and taxonomic incommensurability, despite the fact that there are rebutting defeaters (Mizrahi 2018b, 33-36), no general conclusions about the nature of science can be drawn from one (or even a few) such cases (Mizrahi 2018b, 36-37).

From the fact that one (or a few) cherry-picked episode(s) from the history of science exhibits a particular property, it does not follow that all scientific episodes have that property; otherwise, from the “Piltdown man” episode we would have to conclude that fraud characterizes scientific discovery in general (Mizrahi 2018b, 37-38).

Speaking of scientific discovery, Bryant (2018, 2) takes issue with the fact that I cite “just two authors, Eric Oberheim and Paul Hoyningen-Huene, who use the language of discovery to characterize incommensurability.” For Bryant (2018, 2), this suggests that “it isn’t clear that the assumption Mizrahi takes pains to reject is particularly widespread” (emphasis added). I suppose that “the assumption” in question here is that Kuhn “discovered” incommensurability.

If so, then I would like to clarify that I mention the fact that Oberheim and Hoyningen-Huene talk about incommensurability in terms of discovery, and claim that Kuhn “discovered” it, not to argue against it (i.e., to argue that Kuhn did not discover incommensurability), but rather to show that some of the elements of the Kuhnian image of science, such as incommensurability, are sometimes taken for granted. When it is said that someone has discovered something, it gives the impression that what has been discovered is a fact, and so no arguments are needed.

When it comes to incommensurability, however, it is far from clear that it is a fact about scientific change, and so good arguments are needed in order to establish that episodes of scientific change exhibit taxonomic incommensurability. If I am right, or if Park (2018) and Sankey (2018) are right, then there are no good arguments that establish this.

Not Conclusions, But Questions

In light of the above, I think that the questions raised in the edited volume under review remain urgent (cf. Rehg 2018). Are there good reasons or compelling evidence for the Kuhnian model of theory change in science? If there are no good reasons or compelling evidence for such a model, as I (Mizrahi 2018b), Park (2018), and Sankey (2018) argue, what’s next for philosophers of science? Should we abandon the search for a general theory of science, as Argamakova (2018) suggests? Are there better models of scientific change? Perhaps evolutionary (Marcum 2018) or orthogenetic (Renzi and Napolitano 2018) models?

Bernard Wills (2018) joins Christopher Brown (2017, 2018) in criticizing my defense of Weak Scientism (Mizrahi 2017a, 2017b, 2018a). Unfortunately, it seems that Wills did not read my latest defense of Weak Scientism carefully, nor does he cite any of the other papers in my exchange with Brown. For he attributes to me the view that “other disciplines in the humanities [in addition to philosophy] do not produce knowledge” (Wills 2018, 18).

Of course, this is not my view and I affirm no such thing, contrary to what Wills seems to think. I find it hard to explain how Wills could have made this mistake, given that he goes on to quote me as follows: “Scientific knowledge can be said to be qualitatively better than non-scientific knowledge insofar as such knowledge is explanatorily, instrumentally, and predictively more successful than non-scientific knowledge” (Mizrahi 2018a, 7; quoted in Wills 2018, 18).

Clearly, the claim ‘Scientific knowledge is better than non-scientific knowledge’ entails that there is non-scientific knowledge. If the view I defend entails that there is non-scientific knowledge, then it cannot also be my view that “science produces knowledge and all the other things we tend to call knowledge are in fact not knowledge at all but something else” (Wills 2018, 18).

Even if he somehow missed this simple logical point, reading the other papers in my exchange with Brown should have made it clear to Wills that I do not deny the production of knowledge by non-scientific disciplines. In fact, I explicitly state that “science produces scientific knowledge, mathematics produces mathematical knowledge, philosophy produces philosophical knowledge, and so on” (Mizrahi 2017a, 353). Even in my latest reply to Brown, which is the only paper from my entire exchange with Brown that Wills cites, I explicitly state that, if Weak Scientism is true, then “philosophical knowledge would be inferior to scientific knowledge both quantitatively (in terms of research output and research impact) and qualitatively (in terms of explanatory, instrumental, and predictive success)” (Mizrahi 2018a, 8).

If philosophical knowledge is quantitatively and qualitatively inferior to scientific knowledge, then it follows that there is philosophical knowledge. For this reason, only a rather careless reader could attribute to me the view that “other disciplines in the humanities [in addition to philosophy] do not produce knowledge” (Wills 2018, 18).

There Must Be Some Misunderstanding

Right from the start, then, Wills gets Weak Scientism wrong, even though he later writes that, according to Weak Scientism, “there may be knowledge of some sort outside of the sciences” (Wills 2018, 18). He says that he will ignore the quantitative claim of Weak Scientism and focus “on the qualitative question and particularly on the claim that science produces knowledge and all the other things we tend to call knowledge are in fact not knowledge at all but something else” (Wills 2018, 18). Wills can focus on whatever he wants, of course, but that is not Weak Scientism.

Weak Scientism is not the view that only science produces real knowledge; that is Strong Scientism (Mizrahi 2017a, 353). Rather, Weak Scientism is the view that, “Of all the knowledge we have [i.e., there is knowledge other than scientific knowledge], scientific knowledge is the best knowledge” (Mizrahi 2017a, 354). In other words, scientific knowledge “is simply the best; better than all the rest” (Mizrahi 2017b, 20). Wills’ criticism, then, misses the mark completely. That is, it cannot be a criticism against Weak Scientism, since Weak Scientism is not the view that “science produces knowledge and all the other things we tend to call knowledge are in fact not knowledge at all but something else” (Wills 2018, 18).

Although he deems the quantitative superiority of scientific knowledge over non-scientific knowledge “a tangential point,” and says that he will not spend time on it, Wills (2018, 18) remarks that “A German professor once told [him] that in the first half of the 20th Century there were 40,000 monographs on Franz Kafka alone!” Presumably, Wills’ point is that research output in literature exceeds that of scientific disciplines. Instead of relying on gut feelings and hearsay, Wills should have done the required research in order to determine whether scholarly output in literature really does exceed the research output of scientific disciplines.

If we look at the Scopus database, using the data and visualization tools provided by Scimago Journal & Country Rank, we can see that research output in a natural science like physics and a social science like psychology far exceeds research output in humanistic disciplines like literature and philosophy. On average, psychology has produced 15,000 more publications per year than either literature or philosophy between the years 1999 and 2017. Likewise, on average, physics has produced 54,000 more publications per year than either literature or philosophy between the years 1999 and 2017 (Figure 1). 

Figure 1. Research output in Literature, Philosophy, Physics, and Psychology from 1999 to 2017 (Source: Scimago Journal & Country Rank)

Contrary to what Wills seems to think or what his unnamed German professor may have told him, then, it is not the case that literary scholars produce more work on Shakespeare or Kafka alone than physicists or psychologists produce. The data from the Scopus database show that, on average, it takes literature and philosophy almost two decades to produce what psychology produces in two years or what physics produces in a single year (Mizrahi 2017a, 357-359).

In fact, using JSTOR Data for Research, we can check Wills’ number, as reported to him by an unnamed German professor, to find out that there are 13,666 publications (i.e., journal articles, books, reports, and pamphlets) on Franz Kafka from 1859 to 2018 in the JSTOR database. Clearly, that is not even close to “40,000 monographs on Franz Kafka alone” in the first half of the 20th Century (Wills 2018, 18). By comparison, as of May 22, 2018, the JSTOR database contains more publications on the Standard Model in physics and the theory of conditioning in behavioral psychology than on Franz Kafka or William Shakespeare (Table 1).

Table 1. Search results for ‘Standard Model’, ‘Conditioning’, ‘William Shakespeare’, and ‘Franz Kafka’ in the JSTOR database as a percentage of the total number of publications, n = 12,633,298 (Source: JSTOR Data for Research)

  Number of Publications Percentage of JSTOR corpus
Standard Model 971,968 7.69%
Conditioning 121,219 0.95%
William Shakespeare 93,700 0.74%
Franz Kafka 13,667 0.1%

Similar results can be obtained from Google Books Ngram Viewer when we compare published work on Shakespeare, which Wills thinks exceeds all published work in other disciplines, for he says that “Shakespeare scholars have all of us beat” (Wills 2018, 18), with published work on a contemporary of Shakespeare (1564-1616) from another field of study, namely, Galileo (1564-1642). As we can see from Figure 2, from 1700 to 2000, ‘Galileo’ consistently appears in more books than ‘William Shakespeare’ does.

Racking Up the Fallacies

Wills continues to argue fallaciously when he resorts to what appears to be a fallacious ad hominem attack against me. He asks (rhetorically?), “Is Mr. Mizrahi producing an argument or a mere rationalization of his privilege?” (Wills 2018, 19) It is not clear to me what sort of “privilege” Wills wants to claim that I have, or why he accuses me of colonialism and sexism, since he provides no arguments for these outrageous charges. Moreover, I do not see how this is at all relevant to Weak Scientism. Even if I am somehow “privileged” (whatever Wills means by that), Weak Scientism is either true or false regardless.

After all, I take it that Wills would not doubt his physician’s diagnoses just because he or she is “privileged” for working at a hospital. Whether his physician is “privileged” for working at a hospital has nothing to do with the accuracy of his or her diagnoses. For these reasons, Wills’ ad hominem is fallacious (as opposed to a legitimate ad hominem as a rebuttal to an argument from authority, see Mizrahi 2010). I think that SERRC readers will be better served if we focus on the ideas under discussion, specifically, Weak Scientism, not the people who discuss them.

Speaking of privilege and sexism, however, it might be worth noting that, throughout his paper, Wills refers to me as ‘Mr. Mizrahi’ (rather than ‘Dr. Mizrahi’ or simply ‘Mizrahi’, as is the norm in academic publications), and that he has misspelled my name on more than one occasion (Wills 2018, 18, 22, 24). Studies suggest that addressing female doctors with ‘Ms.’ or ‘Mrs.’ rather than ‘Dr.’ might reveal gender bias (see, e.g., Files et al. 2017). Perhaps forms of address reveal not only gender bias but also ethnic or racial bias when people with non-white or “foreign” names are addressed as Mr. (or Ms.) rather than Dr. (Erlenbusch 2018).

Aside from unsubstantiated claims about the amount of research produced by literary scholars, fallacious appeals to the alleged authority of unnamed German professors, and fallacious ad hominem attacks, does Wills offer any good arguments against Weak Scientism? He spends most of his paper (pages 19-22) trying to show that there is knowledge other than scientific knowledge, such as knowledge produced in the fields of “Law and Music Theory” (Wills 2018, 20). This, however, does nothing at all to undermine Weak Scientism. For, as mentioned above, Weak Scientism is the view that scientific knowledge is superior to non-scientific knowledge, which means that there is non-scientific knowledge; it’s just not as good as scientific knowledge (Mizrahi 2017a, 356).

The Core of His Concept

Wills finally gets to Weak Scientism on the penultimate page of his paper. His main objection against Weak Scientism seems to be that it is not clear to him how scientific knowledge is supposed to be better than non-scientific knowledge. For instance, he asks, “Better in what context? By what standard of value?” (Wills 2018, 23) Earlier he also says that he is not sure what are the “certain relevant respect” in which scientific knowledge is superior to non-scientific knowledge (Wills 2018, 18).

Unfortunately, this shows that Wills either has not read the other papers in my exchange with Brown or at least has not read them carefully. For, starting with my first defense of Weak Scientism (2017a), I explain in great detail the ways in which scientific knowledge is better than non-scientific knowledge. Briefly, scientific knowledge is quantitatively better than non-scientific knowledge in terms of research output (i.e., more publications) and research impact (i.e., more citations). Scientific knowledge is qualitatively better than non-scientific knowledge in terms of explanatory, instrumental, and predictive success (Mizrahi 2017a, 364; Mizrahi 2017b, 11).

Wills tries to challenge the claim that scientific knowledge is quantitatively better than non-scientific knowledge by exclaiming, “Does science produce more knowledge that [sic] anything else? Hardly” (Wills 2018, 23). He appeals to Augustine’s idea that one “can produce a potential infinity of knowledge simply by reflecting recursively on the fact of [one’s] own existence” (Wills 2018, 23). In response, I would like to borrow a phrase from Brown (2018, 30): “good luck getting that published!”

Seriously, though, the point is that Weak Scientism is a thesis about academic knowledge or research. In terms of research output, scientific disciplines outperform non-scientific disciplines (see Figure 1 and Table 1 above; Mizrahi 2017a, 357-359; Mizrahi 2018a, 20-21). Besides, just as “recursive processes can extend our knowledge indefinitely in the field of mathematics,” they can also extend our knowledge in other fields as well, including scientific fields. That is, one “can produce a potential infinity of knowledge simply by reflecting recursively on the” (Wills 2018, 23) Standard Model in physics or any other scientific theory and/or finding. For this reason, Wills’ objection does nothing at all to undermine Weak Scientism.

Wills (2018, 23) tries to problematize the notions of explanatory, instrumental, and predictive success in an attempt to undermine the claim that scientific knowledge is qualitatively better than non-scientific knowledge in terms of explanatory, instrumental, and predictive success. But it seems that he misunderstands these notions as they apply to the scientism debate.

As far as instrumental success is concerned, Wills (2018, 23) asks, “Does science have (taken in bulk) more instrumental success than other knowledge forms? How would you even count given that craft knowledge has roughly 3 million-year head start?” Even if it is true that “craft knowledge has roughly 3 million-year head start,” it is irrelevant to whether Weak Scientism is true or false. This is because Weak Scientism is a thesis about academic knowledge or research produced by academic fields of study (Mizrahi 2017a, 356; Mizrahi 2017b, 11; Mizrahi 2018a, 12).

Solving the Problem and Explaining the Issue

As far as explanatory success is concerned, Wills (2018, 23) writes, “Is science more successful at explanation? Hardly, if science could solve problems in literature or history then these fields would not even exist.” There are a couple of problems with this objection. First, explaining and problem solving are not the same thing (Mizrahi and Buckwalter 2014). Second, what makes scientific explanations good explanations are the good-making properties that are supposed to make all explanations (both scientific and non-scientific) good explanations, namely, unification, coherence, simplicity, and testability (Mizrahi 2017a, 360-362; Mizrahi 2017b, 19-20; Mizrahi 2018a, 17).

I have already made this point several times in my replies to Brown, which Wills does not cite, namely, that Inference to the Best Explanation (IBE) is used in both scientific and non-scientific contexts (Mizrahi 2017a, 362). That is, “IBE is everywhere” (Mizrahi 2017b, 20). It’s just that scientific IBEs are better than non-scientific IBEs because they exhibit more of (and to a greater extent) the aforementioned properties that make any explanation a good explanation (Mizrahi 2018b).

As far as predictive success is concerned, Wills (2018, 23) asks, “Does science make more true predictions? Again how would you even count given that for millions of years, human beings survived by making hundreds of true predictions daily?” There are a few problems with this objection as well. First, even if it is true that “for millions of years, human beings survived by making hundreds of true predictions daily,” it is irrelevant to whether Weak Scientism is true or false, since Weak Scientism is a thesis about academic knowledge or research produced by academic fields of study (Mizrahi 2017a, 356; Mizrahi 2017b, 11; Mizrahi 2018a, 12).

Second, contrary to what Wills (2018, 24) seems to think, testing predictions in science is not simply a matter of making assertions and then checking to see if they are true. For one thing, a prediction is not simply an assertion, but rather a consequence that follows from a hypothesis plus auxiliary hypotheses (Mizrahi 2015). For another, a prediction needs to be novel such that we would not expect it to be the case except from the vantage point of the theory that we are testing (Mizrahi 2012).

As I have advised Brown (Mizrahi 2018, 17), I would also advise Wills to consult logic and reasoning textbooks, not because they provide support for the claim that “science is instrumentally successful, explanatory and makes true predictions,” as Wills (2018, 23) erroneously thinks, but because they discuss hypothesis testing in science. For Wills’ (2018, 24) remark about Joyce scholars suggests a failure to understand how hypotheses are tested in science.

Third, like Brown (2017, 49), Wills (2018, 23) admits that, just like science, philosophy is in the explanation business. For Wills (2018, 23) says that, “certainty, instrumental success, utilitarian value, predictive power and explanation all exist elsewhere in ways that are often not directly commensurable with the way they exist in science” (emphasis added). But if distinct fields of study have the same aim (i.e., to explain), then their products (i.e., explanations) can be evaluated with respect to similar criteria, such as unification, coherence, simplicity, and testability (Mizrahi 2017a, 360-362; Mizrahi 2017b, 19-20; Mizrahi 2018a, 17).

In other words, there is no incommensurability here, as Wills seems to think, insofar as both science and philosophy produce explanations and those explanations must exhibit the same good-making properties that make all explanations good explanations (Mizrahi 2018a, 17; 2018b).

“You Passed the Test!”

If Wills (2018, 24) wants to suggest that philosophers should be “testing their assertions in the ways peculiar to their disciplines,” then I would agree. However, “testing” does not simply mean making assertions and then checking to see if they are true, as Wills seems to think. After all, how would one check to see if assertions about theoretical entities are true? To test a hypothesis properly, one must derive a consequence from it (plus auxiliary assumptions) that would be observed only if the hypothesis (plus the auxiliary assumptions) is true.

Observations and/or experimentation would then indicate to one whether the consequence obtains or not (Mizrahi 2012). Of course, some philosophers have been doing just that for some time now (Knobe 2017). For instance, some experimental philosophers test hypotheses about the alleged intuitiveness of philosophical ideas and responses to thought experiments (see, e.g., Kissinger-Knox et al. 2018). I welcome such empirical work in philosophy.

Contrary to what Wills (2018, 19) seems to think, then, my aim is not to antagonize philosophers. Rather, my aim is to reform philosophy. In particular, as I have suggested in my recent reply to Brown (Mizrahi 2018a, 22), I think that philosophy would benefit from adopting not only the experimental methods of the cognitive and social sciences, as experimental philosophers have done, but also the methods of data science, such as data mining and corpus analysis (see, e.g., Ashton and Mizrahi 2018a and 2018b).

Indeed, the XPhi Replicability Project recently published a report on replication studies of 40 experimental studies according to which experimental studies “successfully replicated about 70% of the time” (Cova et al. 2018). With such a success rate, one could argue that the empirical revolution in philosophy is well under way (see also Knobe 2015). Resistance is futile!

In this paper, I reply to Markus Arnold’s comment and Amanda Bryant’s comment on my work “Can Kuhn’s Taxonomic Incommensurability be an Image of Science?” in Moti Mizrahi’s edited collection, The Kuhnian Image of Science: Time for a Decisive Transformation?.

Arnold argues that there is a gap between the editor’s expressed goal and the actual content of the book. Mizrahi states in the introduction that his book aims to increase “our understanding of science as a social, epistemic endeavor” (2018: 7). Arnold objects that it is “not obvious how the strong emphasis on discounting Kuhn’s incommensurability thesis in the first part of the book should lead to a better understanding of science as a social practice” (2018: 46). The first part of the volume includes my work. Admittedly, my work does not explicitly and directly state how it increases our understanding of science as a social enterprise.

Knowledge and Agreement

According to Arnold, an important meaning of incommensurability is “the decision after a long and futile debate to end any further communication as a waste of time since no agreement can be reached,” and it is this “meaning, describing a social phenomenon, which is very common in science” (Arnold, 2018: 46). Arnold has in mind Kuhn’s claim that a scientific revolution is completed not when opposing parties reach an agreement through rational argumentations but when the advocates of the old paradigm die of old age, which means that they do not give up on their paradigm until they die.

I previously argued that given that most recent past paradigms coincide with present paradigms, most present paradigms will also coincide with future paradigms, and hence “taxonomic incommensurability will rarely arise in the future, as it has rarely arisen in the recent past” (Park, 2018: 70). My argument entails that scientists’ decision to end further communications with their opponents has been and will be rare, i.e., such a social phenomenon has been and will be rare.

On my account, the opposite social phenomenon has been and will rather be very common, viz., scientists keep communicating with each other to reach an agreement. Thus, my previous contention about the frequency of scientific revolutions increases our understanding of science as a social enterprise.

Let me now turn to Bryant’s comment on my criticism against Thomas Kuhn’s philosophy of science. Kuhn (1962/1970, 172–173) draws an analogy between the development of science and the evolution of organisms. According to evolutionary theory, organisms do not evolve towards a goal. Similarly, Kuhn argues, science does not develop towards truths. The kinetic theory of heat, for example, is no closer to the truth than the caloric theory of heat is, just as we are no closer to some evolutionary goal than our ancestors were. He claims that this analogy is “very nearly perfect” (1962/1970, 172).

My objection (2018a: 64–66) was that it is self-defeating for Kuhn to use evolutionary theory to justify his philosophical claim about the development of science that present paradigms will be replaced by incommensurable future paradigms. His philosophical view entails that evolutionary theory will be superseded by an incommensurable alternative, and hence evolutionary theory is not trustworthy. Since his philosophical view relies on this untrustworthy theory, it is also untrustworthy, i.e., we ought to reject his philosophical view that present paradigms will be displaced by incommensurable future paradigms.

Bryant replies that “Kuhn could adopt the language of a paradigm (for the purposes of drawing an analogy, no less!) without committing to the literal truth of that paradigm” (2018: 3). On her account, Kuhn could have used the language of evolutionary theory without believing that evolutionary theory is true.

Can We Speak a Truth Without Having to Believe It True?

Bryant’s defense of Kuhn’s position is brilliant. Kuhn would have responded exactly as she has, if he had been exposed to my criticism above. In fact, it is a common view among many philosophers of science that we can adopt the language of a scientific theory without committing to the truth of it.

Bas van Fraassen, for example, states that “acceptance of a theory involves as belief only that it is empirically adequate” (1980: 12). He also states that if “the acceptance is at all strong, it is exhibited in the person’s assumption of the role of explainer” (1980: 12). These sentences indicate that according to van Fraassen, we can invoke a scientific theory for the purpose of explaining phenomena without committing to the truth of it. Rasmus Winther (2009: 376), Gregory Dawes (2013: 68), and Finnur Dellsén (2016: 11) agree with van Fraassen on this account.

I have been pondering this issue for the past several years. The more I reflect upon it, however, the more I am convinced that it is problematic to use the language of a scientific theory without committing to the truth of it. This thesis would be provocative and objectionable to many philosophers, especially to scientific antirealists. So I invite them to consider the following two thought experiments.

First, imagine that an atheist uses the language of Christianity without committing to the truth of it (Park, 2015: 227, 2017a: 60). He is a televangelist, saying on TV, “If you worship God, you’ll go to heaven.” He converts millions of TV viewers into Christianity. As a result, his church flourishes, and he makes millions of dollars a year. To his surprise, however, his followers discover that he is an atheist.

They request him to explain how he could speak as if he were a Christian when he is an atheist. He replies that he can use the language of Christianity without believing that it conveys truths, just as scientific antirealists can use the language of a scientific theory without believing that it conveys the truth.

Second, imagine that scientific realists, who believe that our best scientific theories are true, adopts Kuhn’s philosophical language without committing to Kuhn’s view of science. They say, as Kuhn does, “Successive paradigms are incommensurable, so present and future scientists would not be able to communicate with each other.” Kuhn requests them to explain how they could speak as if they were Kuhnians when they are not Kuhnians. They reply that they can adopt his philosophical language without committing to his view of science, just as scientific antirealists can adopt the language of a scientific theory without committing to the truth of it.

The foregoing two thought experiments are intended to be reductio ad absurdum. That is, my reasoning is that if it is reasonable for scientific antirealists to speak the language of a scientific theory without committing to the truth of it, it should also be reasonable for the atheist to speak the language of Christianity and for scientific realists to speak Kuhn’s philosophical language. It is, however, unreasonable for them to do so.

Let me now diagnose the problems with the atheist’s speech acts and scientific realists’ speech acts. The atheist’s speech acts go contrary to his belief that God does not exist, and scientific realists’ speech acts go contrary to their belief that our best scientific theories are true. As a result, the atheist’s speech acts mislead his followers into believing that he is Christian. The scientific realists’ speech acts mislead their hearers into believing that they are Kuhnians.

Moore’s Paradox

Such speech acts raise an interesting philosophical issue. Imagine that someone says, “Snow is white, but I don’t believe snow is white.” The assertion of such a sentence involves Moore’s paradox. Moore’s paradox arises when we say a sentence of the form, “P, but I don’t believe p” (Moore, 1993: 207–212). We can push the atheist above to be caught in Moore’s paradox. Imagine that he says, “If you worship God, you’ll go to heaven.” We request him to declare whether he believes or not what he just said. He declares, “I don’t believe if you worship God, you’ll go to heaven.” As a result, he is caught in Moore’s paradox, and he only puzzles his audience.

The same is true of the scientific realists above. Imagine that they say, “Successive paradigms are incommensurable, so present and future scientists would not be able to communicate with each other.” We request them to declare whether they believe or not what they just said. They declare, “I don’t believe successive paradigms are incommensurable, so present and future scientists would not be able to communicate with each other.” As a result, they are caught in Moore’s paradox, and they only puzzle their audience.

Kuhn would also be caught in Moore’s paradox if he draws the analogy between the development of science and the evolution of organisms without committing to the truth of evolutionary theory, pace Bryant. Imagine that Kuhn says, “Organisms don’t evolve towards a goal. Similarly, science doesn’t develop towards truths. I, however, don’t believe organisms don’t evolve towards a goal.” He says, “Organisms don’t evolve towards a goal. Similarly, science doesn’t develop towards truths” in order to draw the analogy between the development of science and the evolution of organisms. He says, “I, however, don’t believe organisms don’t evolve towards a goal,” in order to express his refusal to believe that evolutionary theory is true. It is, however, a Moorean sentence: “Organisms don’t evolve towards a goal. I, however, don’t believe organisms don’t evolve towards a goal.” The assertion of such a sentence gives rise to Moore’s paradox.

Scientific antirealists would also be caught in Moore’s paradox, if they explain phenomena in terms of a scientific theory without committing to the truth of it, pace van Fraassen. Imagine that scientific antirealists say, “The space between two galaxies expands because dark energy exists between them, but I don’t believe that dark energy exists between two galaxies.” They say, “The space between two galaxies expands because dark energy exists between them,” in order to explain why the space between galaxies expands.

They add, “I don’t believe that dark energy exists between two galaxies,” in order to express their refusal to commit to the truth of the theoretical claim that dark energy exists. It is, however, a Moorean sentence: “The space between two galaxies expands because dark energy exists between them, but I don’t believe that dark energy exists between two galaxies.” Asserting such a sentence will only puzzle their audience. Consequently, Moore’s paradox bars scientific antirealists from invoking scientific theories to explain phenomena (Park, 2017b: 383, 2018b: Section 4).

Researchers on Moore’s paradox believe that “contradiction is at the heart of the absurdity of saying a Moorean sentence, but it is not obvious wherein contradiction lies” (Park, 2014: 345). Park (2014: 345) argues that when you say, “Snow is white,” your audience believe that you believe that snow is white. Their belief that you believe that snow is white contradicts the second conjunct of your Moorean sentence that you do not believe that snow is white.

Thus, the contradiction lies in your audience’s belief and the second conjunct of your Moorean sentence. The present paper does not aim to flesh out and defend this view of wherein lies the contradiction. It rather aims to show that Moore’s paradox prevents us from using the language of a scientific theory without committing to the truth of it, pace Bryant and van Fraassen.

The Real Consequences of Speaking What You Don’t Believe

Set Moore’s paradox aside. Let me raise another objection to Bryant and van Fraassen. Imagine that Kuhn encounters a philosopher of mind. The philosopher of mind asserts, “A mental state is reducible to a brain state.” Kuhn realizes that the philosopher of mind espouses the identity theory of mind, but he knows that the identity theory of mind has already been refuted by the multiple realizability argument. So he brings up the multiple realizability argument to the philosopher of mind. The philosopher of mind is persuaded of the multiple realizability argument and admits that the identity theory is not tenable.

To Kuhn’s surprise, however, the philosopher of mind claims that when he said, “A mental state is reducible to a brain state,” he spoke the language of the identity theory without committing to the truth of it, so his position is not refuted by Kuhn. Note that the philosopher of mind escapes the refutation of his position by saying that he did not believe what he stated. It is also reasonable for the philosopher of mind to escape the refutation of his position by saying that he did not believe what he stated, if it is reasonable for Kuhn to escape the refutation of his position by saying that he did not believe what he stated. Kuhn would think that it is not reasonable for the philosopher of mind to do so.

Kuhn, however, might bite the bullet, saying that it is reasonable for the philosopher of mind to do so. The strategy to avoid the refutation, Kuhn might continue, only reveals that the identity theory was not his position after all. Evaluating arguments does not require that we identify the beliefs of the authors of arguments. In philosophy, we only need to care about whether arguments are valid or invalid, sound or unsound, strong or weak, and so on.

Speculating about what beliefs the authors of arguments hold as a way of evaluating arguments is to implicitly rely on an argument from authority, i.e., it is to think as though the authors’ beliefs determine the strength of arguments rather than the form and content of arguments do.

We, however, need to consider under what conditions we accept the conclusion of an argument in general. We accept it, when premises are plausible and when the conclusion follows from the premises. We can tell whether the conclusion follows from the premises or not without the author’s belief that it does. In many cases, however, we cannot tell whether premises are plausible or not without the author’s belief that they are.

Imagine, for example, that a witness states in court that a defendant is guilty because the defendant was in the crime scene. The judge can tell whether the conclusion follows from the premise or not without the witness’s belief that it does. The judge, however, cannot tell whether the premise is plausible or not without the witness’s belief that it is. Imagine that the witness says that the defendant is guilty because the defendant was in the crime scene, but that the witness declares that he does not believe that the defendant was in the crime scene. Since the witness does not believe that the premise is true, the judge has no reason to believe that it is true. It is unreasonable for the judge to evaluate the witness’s argument independently of whether the witness believes or not that the premise is true.

In a nutshell, an argument loses its persuasive force, if the author of the argument does not believe that premises are true. Thus, if you aim to convince your audience that your argument is cogent, you should believe yourself that the premises are true. If you declare that you do not believe that the premises are true, your audience will ask you some disconcerting questions: “If you don’t, why should I believe what you don’t? How can you say to me what you don’t believe? Do you expect me to believe what you don’t?” (Park, 2018b: Section 4).

In case you still think that it is harmless and legitimate to speak what you do not believe, I invite you to imagine that your political rival commits murder to frame you. A false charge is brought to you, and you are tried in court. The prosecutor has a strong indictment against you. You state vehemently that you did not commit murder. You, however, have no physical evidence supporting your statement. Furthermore, you are well-known as a person who speaks vehemently what you do not believe. Not surprisingly, the judge issues a death sentence on you, thinking that you are merely speaking the language of the innocent. The point of this sad story is that speaking what you do not believe may result in a tragedy in certain cases.

A Solution With a Prestigious Inspiration

Let me now turn to a slightly different, but related, issue. Under what condition can I refute your belief when you speak contrary to what you believe? I can do it only when I have direct access to your doxastic states, i.e., only when I can identify your beliefs without the mediation of your language. It is not enough for me to interpret your language correctly and present powerful evidence against what your language conveys.

After all, whenever I present such evidence to you, you will escape the refutation of what you stated simply by saying that you did not believe what you stated. Thus, Bryant’s defense of Kuhn’s position from my criticism above amounts to imposing an excessively high epistemic standard on Kuhn’s opponents. After all, his opponents do not have direct access to his doxastic states.

In this context, it is useful to be reminded of the epistemic imperative: “Act only on an epistemic maxim through which you can at the same time will that it should become a universal one” (Park, 2018c: 3). Consider the maxim “Escape the refutation of your position by saying you didn’t believe what you stated.” If you cannot will this maxim to become a universal one, you ought not to act on it yourself. It is immoral for you to act on the maxim despite the fact that you cannot will it to become a universal maxim. Thus, the epistemic imperative can be invoked to argue that Kuhn ought not to use the language of evolutionary theory without committing to the truth of it, pace Bryant.

Let me now raise a slightly different, although related, issue. Recall that according to Bryant, Kuhn could adopt the language of evolutionary theory without committing to the truth of it. Admittedly, there is an epistemic advantage of not committing to the truth of evolutionary theory on Kuhn’s part. The advantage is that he might avoid the risk of forming a false belief regarding evolutionary theory. Yet, he can stick to his philosophical account of science according to which science does not develop towards truths, and current scientific theories will be supplanted by incommensurable alternatives.

There is, however, an epistemic disadvantage of not committing to the truth of a scientific theory. Imagine that Kuhn is not only a philosopher and historian of science but also a scientist. He has worked hard for several decades to solve a scientific problem that has been plaguing an old scientific theory. Finally, he hits upon a great scientific theory that handles the recalcitrant problem. His scientific colleagues reject the old scientific theory and accept his new scientific theory, i.e., a scientific revolution occurs.

He becomes famous not only among scientists but also among the general public. He is so excited about his new scientific theory that he believes that it is true. Some philosophers, however, come along and dispirit him by saying that they do not believe that his new theory is true, and that they do not even believe that it is closer to the truth than its predecessor was. Kuhn protests that his new theory has theoretical virtues, such as accuracy, simplicity, and fruitfulness. Not impressed by these virtues, however, the philosophers reply that science does not develop towards truths, and that his theory will be displaced by an incommensurable alternative. They were exposed to Kuhn’s philosophical account of science!

Epistemic Reciprocation

They have adopted a philosophical position called epistemic reciprocalism according to which “we ought to treat our epistemic colleagues, as they treat their epistemic agents” (Park, 2017a: 57). Epistemic reciprocalists are scientific antirealists’ true adversaries. Scientific antirealists refuse to believe that their epistemic colleagues’ scientific theories are true for fear that they might form false beliefs.

In return, epistemic reciprocalists refuse to believe that scientific antirealists’ positive theories are true for fear that they might form false beliefs. We, as epistemic agents, are not only interested in avoiding false beliefs but also in propagating “to others our own theories which we are confident about” (Park, 2017a: 58). Scientific antirealists achieve the first epistemic goal at the cost of the second epistemic goal.

Epistemic reciprocalism is built upon the foundation of social epistemology, which claims that we are not asocial epistemic agents but social epistemic agents. Social epistemic agents are those who interact with each other over the matters of what to believe and what not to believe. So they take into account how their interlocutors treat their epistemic colleagues before taking epistemic attitudes towards their interlocutors’ positive theories.

Let me now turn to another of Bryant’s defenses of Kuhn’s position. She says that it is not clear that the analogy between the evolution of organisms and the development of science is integral to Kuhn’s account. Kuhn could “have ascribed the same characteristics to theory change without referring to evolutionary theory at all” (Bryant, 2018: 3). In other words, Kuhn’s contention that science does not develop towards truths rises or falls independently of the analogy between the development of science and the evolution of organisms. Again, this defense of Kuhn’s position is brilliant.

Consider, however, that the development of science is analogous to the evolution of organisms, regardless of whether Kuhn makes use of the analogy to defend his philosophical account of science or not, and that the fact that they are analogous is a strike against Kuhn’s philosophical account of science. Suppose that Kuhn believes that science does not develop towards truths, but that he does not believe that organisms do not evolve towards a goal, despite the fact that the development of science is analogous to the evolution of organisms.

An immediate objection to his position is that it is not clear on what grounds he embraces the philosophical claim about science, but not the scientific claim about organisms, when the two claims parallel each other. It is ad hoc merely to suggest that the scientific claim is untrustworthy, but that the philosophical claim is trustworthy. What is so untrustworthy about the scientific claim, but so trustworthy about the philosophical claim? It would be difficult to answer these questions because the development of science and the evolution of organisms are similar to each other.

A moral is that if philosophers reject our best scientific theories, they cannot make philosophical claims that are similar to what our best scientific theories assert. In general, the more philosophers reject scientific claims, the more impoverished their philosophical positions will be, and the heavier their burdens will be to prove that their philosophical claims are dissimilar to the scientific claims that they reject.

Moreover, it is not clear what Kuhn could say to scientists who take the opposite position in response to him. They believe that organisms do not evolve towards a goal, but refuse to believe that science does not develop towards truths. To go further, they trust scientific claims, but distrust philosophical claims. They protest that it is a manifestation of philosophical arrogance to suppose that philosophical claims are worthy of beliefs, but scientific claims are not.

This possible response to Kuhn reminds us of the Golden Rule: Treat others as you want to be treated. Philosophers ought to treat scientists as they want to be treated, concerning epistemic matters. Suppose that a scientific claim is similar to a philosophical claim. If philosophers do not want scientists to hold a double standard with respect to the scientific and philosophical claims, philosophers should not hold a double standard with respect to them.

There “is no reason for thinking that the Golden Rule ranges over moral matters, but not over epistemic matters” (Park, 2018d: 77–78). Again, we are not asocial epistemic agents but social epistemic agents. As such, we ought to behave in accordance with the epistemic norms governing the behavior of social epistemic agents.

Finally, the present paper is intended to be critical of Kuhn’s philosophy of science while enshrining his insight that science is a social enterprise, and that scientists are social epistemic agents. I appealed to Moore’s paradox, epistemic reciprocalism, the epistemic imperative, and the Golden Rule in order to undermine Bryant’s defenses of Kuhn’s position from my criticism. All these theoretical resources can be used to increase our understanding of science as a social endeavor. Let me add to Kuhn’s insight that philosophers are also social epistemic agents.

This volume is divided into four parts, in which its contributors variously Question, Defend, Revise, or Abandon the Kuhnian image of science. One immediately wonders: what is this thing, the Kuhnian Image of Science? It isn’t a question that can be decisively or quickly settled, of course. Perhaps one of the reasons why so much has been written on Kuhn’s philosophy of science is that it gives rise to such rich interpretive challenges.

Informed general philosophy of science readers will of course know the tagline version of Kuhn’s view — namely, that the development of science unfolds in wholesale revolutions of scientific paradigms that are in some sense incommensurable with one another. However, one might think that whatever the image of science at issue in this volume is, it should be a sharper image than that.

Many Thomases Kuhn

But of course there isn’t really a single, substantive, cohesive, uncontroversial image at issue. Alexandra Argamakova rightly points out in her contribution, “there exist various images of science belonging to different Thomas Kuhns at different stages of his work life and from different perspectives of interpretation, so the target for current analysis turns out to be less detectable” (46). Rather, the contributors touch on various aspects of Kuhn’s philosophy, variously interpreted — and as such, multiple Kuhnian images emerge as the volume unfolds. That’s just as it should be. In fact, if the volume had propped up some caricature of Kuhn’s views as the Kuhnian image of science, it would have done a disservice both to Kuhn and to his many interpreters.

One wonders, too, whether the so-called Kuhnian image of science is really so broadly endorsed as to be the potential subject of (echoing Kuhn’s own phrase) a ‘decisive transformation’. In his introduction, Moti Mizrahi emphasizes Kuhn’s undeniable influence. Kuhn has, Mizrahi points out, literally tens of thousands of citations; numerous books, articles, and journal issues devoted to his work; and a lasting legacy in the language of academic and public discourse. While all of this signals influence, it’s clearly no indication of agreement.

To be fair, Mizrahi acknowledges the “fair share” of Kuhn critics (2). Nevertheless, if the prospect of decisively transforming the Kuhnian image of science were to be a serious prospect, then the image would have to be widely accepted and enjoy a lasting relevance. However, Argamakova again rightly emphasizes that Kuhn’s philosophy of science “never fully captured the intellectual market” (45) and “could not be less attractive for so many minds!” (47). Moreover, in a remarkable passage in his contribution, Howard Sankey describes a central component of the so-called Kuhnian image of science as as an old battlefield and a dead issue:

Returning to the topic from the perspective of the contemporary scene in the philosophy of science is like visiting a battlefield from a forgotten war. The positions of the warring sides may still be made out. But the battlefield is grown over with grass. One may find evidence of the fighting that once took place, perhaps bullet marks or shell holes. But the fighting ceased long ago. The battle is a thing of the past.

The problem of incommensurability is no longer a live issue. The present chapter has taken the form of a post-mortem examination of a once hotly debated but now largely forgotten problem from an earlier period in the philosophy of science. (87)

If the same holds true for the rest of the Kuhnian image (or images), then the volume isn’t exactly timely.

But dead philosophical issues don’t always stay dead. Or rather, we’re not always right to pronounce them dead. In 1984, Arthur Fine famously proclaimed scientific realism “well and truly dead” (in The Natural Ontological Attitude), and clearly he was quite wrong. At any rate, we may find interest in an issue, dead or not, and there is certainly much of it to be found in this volume. I have been asked to focus my comments on the second half of the book. As such, I will discuss the Introduction, as well as Parts I and II in brief, then I will discuss parts III and IV at greater length.

On the Incommensurable

In his Introduction, Mizrahi argues that, far from initiating a historical turn in the philosophy of science, Kuhn was ‘patient zero’ for anecdotiasis — “the tendency to use cherry-picked anecdotes or case studies… to support general claims (about the nature of science as a whole)” (3). Mizrahi argues that anecdotiasis is pervasive, since significant proportions of articles in the PhilSci-Archive and in leading philosophy of science journals contain the phrase ‘case study’.

But neither using the phrase ‘case study’ nor doing case studies is inherently or self-evidently problematic. Case studies can be interesting, informative, and evidential. Of course the challenges are not to ignore relevant problem cases, not to generalize hastily, and not to assign undue evidential weight to them. But if we are to suppose that all or most philosophers of science who use case studies fail to meet those challenges, we will need a substantial body of evidence.

Part I begins with Mizrahi’s contribution, which the successive contributions all engage. In it, he defines taxonomic incommensurability as conceptual incompatibility between new and old theories. Against those who claim that Kuhn ‘discovered’ incommensurability, Mizrahi argues that there are no good deductive or inductive arguments for taxonomic incommensurability. He cites just two authors, Eric Oberheim and Paul Hoyningen-Huene, who use the language of discovery to characterize incommensurability. As such, it isn’t clear that the assumption Mizrahi takes pains to reject is particularly widespread.

Nevertheless, even if everyone universally agreed that there are no legitimate cases of incommensurability, it would still be useful to know why they’d be justified in so thinking. So the work that Mizrahi does to establish his conclusion is valuable. He shows the dubious sorts of assumptions that arguments for the taxonomic incommensurability thesis would hang on.

Argamakova’s helpful and clear contribution lays out three general types of critique with respect to Kuhn’s view of scientific development — ambiguity, inaccuracy, and limitation — and raises, if tentatively, concerns about Kuhn’s universalist ambitions. She might have been more explicit with respect to the force and scope of her comments on universalism — in particular, whether she sees the flaws in Kuhn’s theory as ultimately stemming from his attempts at universal generalizations, and to what extent her concerns extend beyond Kuhn to general philosophy of science.

Seungbae Park advances several arguments in response to Kuhn’s incommensurability thesis. One such argument takes up Kuhn’s analogy in The Structure of Scientific Revolutions (henceforth Structure) between the development of science and the evolution of organisms. Park suggests that in drawing the analogy, Kuhn illicitly assumes the truth of evolutionary theory. He doesn’t consider that Kuhn could adopt the language of a paradigm (for the purposes of drawing an analogy, no less!) without committing to the literal truth of that paradigm.

Park also claims that “it is self-defeating for Kuhn to invoke a scientific theory to give an account of science that discredits scientific claims” (66), when it’s not clear that the analogy is at all integral to Kuhn’s account. Kuhn could, for instance, have ascribed the same characteristics to theory change without referring to evolutionary theory at all.

Sankey’s illuminating contribution fills in the interpretive background on incommensurability — the semantic version of Kuhn’s incommensurability thesis, in particular. He objects, with Mizrahi, to the language of discovery used by Oberheim and Hoyningen-Huene with respect to incommensurability. He argues, convincingly, that the purported paradigm shift that allowed Kuhn to finally comprehend Aristotle’s physics isn’t a case of incommensurability, but rather of comprehension after an initial failure to understand. While this doesn’t establish his conclusion that no cases of incommensurability have been established (76), it does show that a historically significant purported case is not genuine.

Vasso Kindi fills in some historical detail regarding the positivist image of science that Kuhn sought to replace and the “stereotypical” image attributed to him (96). She argues that Kuhn’s critics (including by implication several of her co-contributors) frequently attack a strawman — that, notwithstanding Kuhn’s avowed deference to history, the Kuhnian image of science is not meant to be a historical representation, and so doesn’t need to be supported by historical evidence. It is, rather, a “a philosophical model that was used to challenge an ideal image of science” (95).

Finally, Lydia Patton emphasizes the practical dimension of Kuhn’s conception of paradigms in Structure. It ought to be uncontroversial that on Kuhn’s early characterization a paradigm is not merely a theory, but a series of epistemic, evaluative, and methodological practices, too. But Patton argues that there has been too strong a semantic tendency in the treatment of Kuhnian paradigms (including by the later Kuhn himself). She argues for the greater interest and value of a practical lens on Kuhn’s project for the purposes of understanding and explaining science.

Vectors of Glory

Andrew Aberdein’s contribution deals with the longstanding and intriguing question of whether there are revolutions in mathematics. He imports to that discussion distinctions he drew in previous work among so-called glorious, inglorious, and paraglorious revolutions, in which, respectively, key components of the theory are preserved, lost, or preserved with new additions. Key components are, he says, “at least all components without which the theory could not be articulated” (136).

He discusses several examples of key shifts in mathematical theory and practice that putatively exemplify certain of these classes of revolution. The strength of the paper is its fascinating examples, particularly the example of Inter-Universal Teichmüller theory, which, Aberdein explains, introduces such novel techniques and concepts that some leading mathematicians say its proofs read as if they were “from the future, or from outer space” (145).

Aberdein doesn’t falsely advertise his thesis. He acknowledges that “it is not easy to determine whether a given episode is revolutionary” (140), and claims only that certain shifts “may be understood” as revolutionary (149) — that the cases he offers are putative mathematical revolutions. As to how we should go about identifying putative mathematical revolutions, Aberdein suggests we look directly for conceptual shifts (or ‘sorites-like’ sequences of shifts) in which key components have been lost or gained.

A fuller discussion of these diagnostics is needed, since the judgment of whether there are revolutions (genuine or putative) in mathematics will hang largely on diagnostics such as these. Is any key conceptual shift sufficient? If so, have we really captured the spirit of Kuhn’s view, given that Kuhn seems to ascribe a certain momentousness to revolutions? If the conceptual shift has to be substantial, how substantial, and how should we gauge its substantiality? Without some principled, non-arbitrary, and non-question-begging standards for what counts as a revolution, we cannot hope to give a serious answer to the question of whether there are, even putatively, revolutions in mathematics.

The paper would also have benefited from a more explicit discussion of what a mathematical paradigm is in the first place, especially as compared to a scientific one. We can infer from Aberdein’s examples that conceptions of number, ratio, proportion, as well as systems of conjecture and mathematical techniques belong to mathematical paradigms — but explicit comment on this would have been beneficial.

Moreover, Aberdein sees an affinity between mathematics and science, commenting toward the end of the paper that the methodology of mathematics is not so different from that of science, and that “the story we tell about revolutions [should] hold for both science and mathematics” (149). These are loaded comments needing further elaboration.

The Evolution of Thomas Kuhn

In his contribution, James Marcum argues that Kuhn’s later evolutionary view is more relevant to current philosophy of science (being ‘pluralistic and perspectival’) than his earlier revolutionary one. On Kuhn’s later evolutionary view, Marcum explains, scientific change proceeds via “smaller evolutionary specialization or speciation” (155), with a “gradual emergence of a specialty’s practice and knowledge” (159). On this view, scientific development consists in “small incremental changes of belief” rather than “the upheaval of world-shattering revolutions” (159).

Marcum uses the emergence of bacteriology, virology, and retrovirology to illustrate the strengths and weaknesses of Kuhn’s evolutionary view. Its main strength, he says, is that it illuminates the development of and relationships among these sorts of scientific specialties; its weakness is that it ascribes a single tempo — Darwinian gradualism — and a single mode — speciation — to the evolution of science. Marcum adopts George Gaylord Simpson’s “richer and more textured approach” (165), which distinguishes several tempos and modes. Since these refinements better enable Kuhn’s view to handle a range of cases, they are certainly valuable.

According to Marcum, current philosophy of science is ‘pluralistic and perspectival’ in its recognition that different sciences face different philosophical issues and in its inclusion of perspectives from outside the logico-analytic tradition, such as continental, pragmatist, and feminist perspectives (166). Marcum seems right to characterize current philosophy of science as pluralistic, given the move away from general philosophy of science to more specialized branches.

If this pluralism is to be embraced, one might wonder what role (if any) remains for general philosophy of science. Marcum makes the interesting suggestion that a general image of science, like Kuhn’s evolutionary image, while respecting our contemporary pluralistic stance, can at the same time offer “a type of unity among the sciences, not in terms of reducing them to one science, but rather with respect to mapping the conceptual relationships among them” (169).

One of Marcum’s central aims is to show that incommensurability plays a key explanatory role in a refined version of Kuhn’s evolutionary image of science. The role of incommensurability on this view is to account for scientific speciation. However, Marcum shows only that we can characterize scientific speciation in terms of incommensurability, without clearly establishing the explanatory payoff of so doing. He does not succeed in showing that incommensurability has a particularly enriching explanatory role, much less that incommensurability is “critical for conceptual evolution within the sciences” or “an essential component of… the growth of science” (168).

All a Metaphor?

Barbara Gabriella Renzi and Giulio Napolitano frame their contribution with a discussion of competing accounts of the nature and role of metaphor. They avow the commonly accepted view that metaphors are not merely linguistic, but cognitive, and that they are ubiquitous. They claim, I would think uncontroversially, that metaphors shape how individuals approach and reason about complex issues. They also discuss historical empiricist attitudes toward metaphor, competing views on the role of models and metaphor in science, and later, the potential role of metaphor in social domination.

Renzi and Napolitano also address Kuhn’s use of the metaphor of Darwinian evolution to characterize scientific change. They suggest that an apter metaphor for scientific change can be made of the obsolete orthogenetic hypothesis, according to which “variations are not random but directed by forces regulated and ultimately directed by the internal constitution of the organism, which responds to environmental stimuli” (184).

The orthogenetic metaphor is a better fit for scientific change, they argue, because the emergence of new ideas in science is not random, but driven by “arguments and debates… specific needs of a scientist or group of scientists who have been seeking a solution to a problem” (184).

The orthogenetic metaphor effectively highlights a drawback of the Darwinian metaphor that might otherwise be overlooked, and deserves further attention. The space devoted to discussing metaphor in the abstract contributes little to the paper, beyond prescriptions to take metaphor seriously and approach it with caution. Much of that space would have been better devoted to using historical examples to compare Kuhn’s Darwinian metaphor to the proposed orthogenetic alternative, to make concrete the fruitfulness of the latter, and to flesh out the specific kinds of internal and external pressures that Renzi and Napolitano see as important drivers of scientific change.

Methodological Contextualism

Darrell Rowbottom offers a summary and several criticisms of what he sees as Kuhn’s early-middle period image of science. By way of criticism, he points out that it isn’t clear how to individuate disciplinary matrices in a way that preserves a clear distinction between normal and extraordinary science, or ensures that what Kuhn calls ‘normal science’ is really the norm. Moreover, in linking the descriptive and normative components of his view, Kuhn implausibly assumes that mature science is optimal.

Rowbottom suggests a replacement image of science he calls methodological contextualism (developed more fully in previous work). Methodological contextualism identifies several roles — puzzle-solving, critical, and imaginative — which scientific practitioners fulfill to varying degrees and in varying combinations. The ideal balance of these roles depends on contextual factors, including the scientists available and the state of science (200).

The novel question Rowbottom considers in this paper is: how could piecemeal change in science be rational from the perspective of methodological contextualism? I have difficulty seeing why this is even a prima facie problem for Rowbottom’s view, since puzzle-solving, critical and imaginative activities are clearly consonant with piecemeal change. I suppose it is because the view retains some of Kuhn’s machinery, including his notion of a disciplinary matrix.

At any rate, Rowbottom suggests that scientists may work within a partial disciplinary matrix, or a set of partially overlapping ones. He also makes the intriguing claim that “scientists might allow inconsistency at the global level, and even welcome it as a better alternative than a consistent system with less puzzle-solving power” (202). One might object that Kuhn’s incommensurability thesis seems to block the overlapping matrix move, but Rowbottom proclaims that the falsity of Kuhn’s incommensurability thesis follows “as a consequence of the way that piecemeal change can occur” (201). One person’s modus ponens is another’s modus tollens, as they say.

A Digestible Kuhn

The brevity of the contributions makes them eminently digestible and good potential additions to course syllabi at a range of levels; on the other hand, it means that some of the most provocative and topical themes of the book — such as the epistemic and methodological status of generalizations about science and the role of general philosophy of science in contemporary philosophy — don’t get the full development they deserve. The volume raises more questions than it satisfactorily addresses, but several of them bring renewed relevance and freshness to Kuhnian philosophy of science and ought to direct its future course.

Twenty-two years after his death, Thomas Kuhn’s work is still able to provoke lively debates, where arguments are exchanged and competing interpretations of his theories are advanced. The Kuhnian Image of Science is a good example, as the book brings together ten scholars in a debate for and against Thomas Kuhn’s legacy. The question, the edited volume raises, is straightforward:

“Does the Kuhnian image of science provide an adequate model of scientific change? If we abandon the Kuhnian picture of revolutionary change and incommensurability […], what consequences would follow from that vis-à-vis our understanding of science as a social, epistemic endeavor?” (7)

In this review I will concentrate on the first two parts of the book, i.e. and in particular on the debate between those who are questioning (Mizrahi, Argamakova, Park, Sankey), and those who are defending Kuhn (Kindi, Patton), since their arguments are closely related. Therefore, I will discuss some of their major arguments in topological order.

Debating Kuhn’s Evidence

The editor Moti Mizrahi opens the debate in his introduction with a confrontational thesis: Kuhn, in his opinion, is responsible for an “infectious disease” (3), for “the pathological state of the field of philosophy of science in general, and general philosophy of science in particular” (3). Kuhn’s vice is his use of case studies (from the history of science) as arguments, although – according to Moti Mizrahi – they are nothing more than “anecdotal evidence” leading to “hasty generalizations” and “fallacious inductive reasoning” (6).

Hearing the trumpets of the troops ready to battle one is eager to learn how to do it right: How the standards of inductive reasoning within philosophy of science are re-erected. Yet, anticipating one of the results of this review, the “inductive reasoning” intended to refute Kuhn’s incommensurability thesis (found in the first part of the book) is actually its weakest part.

However, to understand the intricacy of this difficult task, we have to recognize, that it is not easy to support or falsify inductively a complex theory of science. Broadly speaking, in Kuhn’s account we should empirically observe sciences displaying at least four different manifestations: (1.) “proto-science” in the pre-paradigm phase, when there is no general consensus about theories, methods and standards, (2.) “normal science”, when scientists are most of the time focused on preserving, but also adapting existing paradigms to new problems and new scientific fields, (3.) sciences in a state of crisis, when more and more “anomalies” occur, which defy explanations in conformity with established procedures, and finally (4.) on rare occasions a “revolutionary” state, when different paradigms compete with each other and scientific theories based on one paradigm are to some extent “incommensurable” with those based on another paradigm.

There are good reasons to suppose that Kuhn’s somehow schematic and ideal-typical description of scientific change is too simple compared with the complexities shown by many historical case studies. Nevertheless, the counter-arguments under consideration brought forward against his model seem, paradoxically, to underestimate the complexity of Kuhn’s claims. For example, in Kuhn’s Incommensurability Thesis Mizrahi decides to discuss scientific change only in general.  He claims that Kuhn argues:

“Scientific change (specifically, revolutionary change) is characterized by taxonomic incommensurability.” (33)

The compounded phrase “[s]cientific change (specifically, revolutionary change)” indicates that, in Mizrahi’s interpretation, for Kuhn not all scientific change is per definition revolutionary. But then arguments against Kuhn’s theory should consider at least two kinds of scientific change separately: revolutionary change and those (commensurable) non-revolutionary scientific changes within “normal science.”

Keeping in mind that for Kuhn theory change is possible to a certain degree within normal science (only changing paradigms must be averted)[1], it is not clear, why Kuhn’s “image of science” should be dismissed because “as far as theory change is concerned” taxonomic incommensurability “is the exception rather than the rule” (38).[2]

Or another example, in Can Kuhn’s Taxonomic Incommensurability Be an Image of Science? where Seungbae Park comes to the conclusion that historical evidence shows that “scientific revolution is rare, taxonomic incommensurability is rare, and taxonomic commensurability is common” (61). It is, for similar reasons, unclear why this conclusion should not be commensurable with Kuhn’s description of normal science, since Kuhn claimed that normal science is common and scientific revolutions are rare.

However, this is not Park’s last argument about scientific change: He asks furthermore if we should not distinguish between the distant scientific past, when scientific revolutions were more common, and the recent past, “since most recent past theories have been stable, most present theories will also be stable” (70). Kuhn’s theory of revolutionary paradigm change is, in his opinion, first of all not appropriate for understanding the development of contemporary and future science.

Incommensurable Paradigms of Language?

After a discussion of the critical reception of Thomas Kuhn’s and Paul Feyerabend’s work and the objections raised against their claim that scientific theories or paradigms are incommensurable, Howard Sankey admits in The Demise of the Incommensurability Thesis that:

“the idea that there is conceptual change in science now seems commonplace. But the much-feared consequences, such as incomparability, communication breakdown, and irrationality now all seem to have been greatly overblown.” (88)

Prima facie it seems like a self-critical admission of an inappropriate former reception of Kuhn’s theory of incommensurability, especially by those philosophers of science who tried to fight “irrationality” with the means of referential semantics. However, Sankey seems to think that the dissolution of the exaggerated accusations of Kuhn’s critics somehow makes now Kuhn’s theory of incommensurability obsolete. Hence, Sankey can summarize:

“with the demise of the incommensurability thesis, the debate about scientific realism is free to proceed in a manner that is unencumbered by the semantic concerns about wholesale referential discontinuity that were prompted by the incommensurability thesis.” (88)

For Sankey, Kuhn’s concept of incommensurability is dead (87). He seems to blame Kuhn for the misguided interpretations of his opponents. It comes down to the argument: if it’s not possible to criticize Kuhn’s concept of incommensurability as “irrational” anymore, then Kuhn’s concept cannot claim any relevance for future discussions.

However, more importantly: These arguments against Kuhn are based on referential semantics, i.e. semantic concerns about referential continuity. Hence, what their objections against Kuhn’s incommensurability theory inadvertently show is, paradoxically, the incommensurability of competing paradigms of language. This becomes apparent, for example, when Mizrahi criticizes Kuhn’s sometimes-vague formulations, especially in his early Structure. Mizrahi refers to statements where Kuhn argues with caution:

“The normal-scientific tradition that emerges from a scientific revolution is not only incompatible but often [sic] actually incommensurable with that which has gone before.” (Kuhn 1996, 103)

Formulations such as this prompt Mizrahi to ask: If taxonomic incommensurability (TI):

“is not a general thesis about the nature of scientific change, then what is its explanatory value? How does (TI) help us in terms of understanding the nature of scientific change? On most accounts of explanation, an explanans must have some degree of generality […] But if (TI) has no degree of generality, then it is difficult to see what the explanatory value of (TI) is.” (37)

Kuhn could have responded that his arguments in Structure are explicitly based on Wittgenstein’s theory of “language games” with its central concept of “family resemblance”, which by definition does not allow the assumption that there are unambiguous conceptual boundaries and a distinguishing characteristic, which all or even most of the phenomena aligned by a concept have in common.[3]

Indeed, understanding Wittgenstein’s concept of “family resemblance” is central to understand Kuhn’s theory of “paradigms”, “paradigm shifts”, and the meaning of “incommensurability”.[4] Yet, it is possible to come to similar conclusions without referring to the late Wittgenstein: For example, Alexandra Argamakova despite of her negative evaluation of many of Kuhn’s arguments, unlike Mizrahi, is closer on this issue to Kuhn where she claims in Modeling Scientific Development: “distinct breakthroughs in science can be marked as revolutions, but no universal system of criteria for such appraisal can be formulated in a normative philosophical manner” (54).

Defending Kuhn’s Epistemology

In two of the book’s most interesting discussions of Kuhn’s epistemology, Vasso Kandi’s The Kuhnian Straw Man and Lydia Patton’s Kuhn, Pedagogy, and Practice, the allegation that Kuhn developed his theory on the basis of selected historical cases is refuted. Furthermore, Kindi, defending the innovative character of Kuhn’s work asks “for a more faithful reading”:

“Kuhn’s new image of science, which is actually a mosaic of different traditions, was not put together by generalizing from instances; it emerged once attention was drawn to what makes scientific practice possible, namely paradigms and what follows from them (normal science, anomalies, revolutions). In accordance with Kuhn’s own understanding of scientific revolutions, his revolution in the perception of science did not have to summon new facts or make new discoveries; it only needed a new perspective.” (104)

While Lydia Patton forcefully argues that:

“Kuhn’s original work did not restrict ‘paradigm’ to ‘theoretical framework’, nor did he restrict the perspective of scientific practice to the content of propositions with a truth-value. And it is mainly because Kuhn’s arguments in Structure are outside the semantic view, and focus instead on the practice of science, that they are interesting and fresh.” (124)

Both, Patton and Kindi, offer a close reading of Kuhn’s work, trying to give new perspectives on some of the more contested concepts in Kuhn’s epistemology.

The Social in Social Epistemology

One explicit aim of this edited volume is, as the editor asserts, to outline what consequences would follow from this debate for “our understanding of science as a social, epistemic endeavor” (7). But for this reviewer it is not obvious how the strong emphasis on discounting Kuhn’s incommensurability thesis in the first part of the book should lead to a better understanding of science as a social practice.

Kuhn’s theory of incommensurability of competing paradigms is precisely the point within his epistemology where value judgments and social decisions come into play. While traditionally those who defended the “progress of science” (cf. Sankey: 87) against what they saw as Kuhn’s “anti-realist” position were often those who wanted to defend the objectivity of science by excluding “external” influences, like the “social” and the political, from the scientific core.[5]

It is therefore important when talking about incommensurability of paradigms, and the possibility of a “communication breakdown”, to distinguish between two distinct meanings: (a) the impossibility to communicate at all because people do not understand each other’s language or paradigms and (b) the decision after a long and futile debate to end any further communication as a waste of time since no agreement can be reached. It is this second meaning, describing a social phenomenon, which is very common in science. Sankey argues against the first meaning when he declares:

“Given that scientists are able to understand what is said by theories whose terms are untranslatable into their own, no insuperable obstacle stands in the way of full communication between the ‘proponents of competing paradigms.’” (87)

While Sankey “wonders what all the fuss was about” (87), he has only shown (in accordance with Kuhn: cf. Kuhn 2000) that in theory full communication may be possible, but not that communication breakdowns are not common between scientists working with different paradigms. While on a theoretical level these workday problems to communicate may seem, for some philosophers of science, trivial. However, on the social level for working scientists, such communication breakdowns are often not only the reason for fraught relations between colleagues, but also for disciplinary segmentation and sometimes for re-drawing boundaries of scientific disciplines.

Perhaps it is no coincidence that in this volume those who discuss social as well as epistemological practices of scientists are not those who criticize incommensurability from a semantic point of view. Social and epistemological practices are considered in one way or the other by those defending Kuhn, like Kindi and Patton, and those whose main concern is to revise certain aspects of Kuhn’s image of science, like James A. Marcum, Barbara Gabriella Renzi & Giulio Napolitano, and David P. Rowbottom.

However, as I confined this review to the discussion of the first six articles I can only point out that the four remaining articles go beyond the topics discussed thus far and would deserve not only attentive readers but also a thorough discussion. They analyze, for example, scientific revolutions in mathematics (Andrew Aberdein), the role of evolutionary metaphors (Gabriella Renzi/Napolitano, Marcum) and of methodological contextualism in the philosophy of science (Rowbottom). Hence, although this edited volume has some weaknesses, there are several contributions, which open new avenues of thought about Kuhn, and are worth reading for those interested in Kuhn and in philosophy of science.

Moti Mizrahi has been defending something he calls ‘weak scientism’ against Christopher Brown in a series of exchanges in the Social Epistemology Review and Reply Collective. His animus seems to be against philosophy in particular though he asserts that other disciplines in the humanities do not produce knowledge either. He also shows remarkable candor in admitting that it all comes down to money: money spent on philosophy would be better spent on the sciences because scientific knowledge is better qualitatively (i.e. because it makes true predictions) and quantitatively (scientists pump out more stuff than philosophers). (11)

Measuring Success

As he tells us: “Scientific knowledge can be said to be qualitatively better than non-scientific knowledge insofar as such knowledge is explanatorily, instrumentally and predictively more successful than non-scientific knowledge.” (Mizrahi; 7). Furthermore: “Scientific knowledge can be said to be quantitatively better than non-scientific knowledge insofar as scientific disciplines produce more impactful knowledge- in the form of scholarly publications-than non-scientific disciplines (as measured by research output and research impact)” (7)

The relevance of this latter claim seems to me unclear: surely by a quantitative measure, Shakespeare scholars have all of us beat.[1] A German professor once told me that in the first half of the 20th Century there were 40,000 monographs on Franz Kafka alone! I will not, however, spend time scratching my head over what seems a tangential point. The quantity of work produced in the sciences would be of little significance were it not valuable by some other measure. No one would think commercials great works of art on the grounds that there are so many of them.

Then again some concerned by the problem of over-specialization might view the sheer quantity of scientific research as a problem not an advantage.  I will focus, then, on the qualitative question and particularly on the claim that science produces knowledge and all the other things we tend to call knowledge are in fact not knowledge at all but something else. I will then consider Mr. Mizrahi’s peculiar version of this claim ‘weak scientism’ which is that while there may be knowledge of some sort outside of the sciences (it is hard, he thinks, to show otherwise) this knowledge is of a qualitatively lesser kind.

He says this is so “in certain relevant aspects”. (10) I’m not sure what he means by this hedge. What makes an aspect relevant in this context? I will proceed though on the assumption that whatever these relevant aspects are they make for an over-all context independent superiority of science over non-science.[2]

Of course, were I a practitioner of the hermeneutic of suspicion I would point out the glaring conflict of interest in Mr. Mizrahi making these claims from the fastness of a technical institute. If someone pops up claiming that only half the university really earns its keep it is a little bit suspect (if not surprising exactly) when that half of the university happens to the very one in which he resides. I might also point out the colonialist and sexist implications of his account, which is so contrived to conveniently exclude all sorts of ‘others’ from the circle of knowledge. Is Mr. Mizrahi producing an argument or a mere rationalization of his privilege?

However, as Mr. Mizrahi seems unlikely to be overly impressed by such an analysis I will stick to something simpler.[3] Does science alone produce knowledge or do other epistemic forms produce knowledge as well? This is the question of whether ‘strong scientism’ is correct. Secondly, if strong scientism is not correct does weak scientism offer a more defensible alternative or does it suffer from the same drawbacks? Accordingly, I will refute strong scientism and then show that weak scientism is vulnerable to precisely the same objections.

Politicized Words and Politicizing Ideas

There are dangers to antagonizing philosophers. We may not be pulling in the big grants, true , but we can do a great deal of damage regardless  for when the ‘scientistic class’ is not accusing philosophy of being useless and ineffectual it is accusing it of corrupting the entire world with its po-mo nonsense.[4] This is because one of the functions of philosophy is the skeptical or critical one. When scientists go on about verification and falsification or claim the principle of induction can be justified by induction philosophers perform the Socratic function of puncturing their hubris. Thus, one of the functions of philosophy is deflationary.

A philosopher of science who makes himself unpopular with scientists by raising questions the scientist is unequipped to answer and has no time for anyway is only doing her job. I think this is a case in point. Since Descartes at least we been fascinated by the idea of the great epistemic purge. There is so much ‘stuff’ out there claiming to be knowledge that we need to light a great bonfire and burn all of it. This bonfire might be Cartesian doubt. It might be ‘scientific method’. Either way all the ‘pretend’ knowledge is burned off leaving the useful core. This may well be a worthwhile endeavour and in the time of Descartes it surely was.

However, I suspect this tradition has created a misleading impression. The real problem is not that we have too little knowledge but too much: as a phenomenologist might say it is a saturated phenomenon. Knowledge is all around us so that like bats our eyes are blinded by the sun. This is why I find the idea that only scientists produce knowledge the very definition of an ivory tower notion that has no basis in experience. To show this let me make a list of the kinds of non-scientific knowledge people have.

As we shall see, the problem is not making this list long but keeping it short. I offer this list to create an overwhelming presumption that strong scientism at very least is not true (I shall then argue that weak scientism is in no better a case).  This procedure may not be decisive in itself but I do think it puts the ball in the court of the ‘strong scientist’ who must show that all the things I (and most everybody else) call knowledge are in fact something else.

What is more, the ‘strong scientist’ must do this without violating the criterion of strong scientism itself: he cannot avail himself of any but scientific arguments. Moreover, he must show that science itself meets the criterion of knowledge he sets out which is not an easy task given such well known difficulties as the problem of induction. At any rate, prima facie, there seems overwhelming empirical evidence that strong scientism is incorrect: a claim so extraordinary should have an unusually strong justification, to paraphrase Hume. Let’s see if the ‘strong scientist’ can produce one.

Making a Problem of “Results”

To begin, I should point out is that there are bodies of knowledge that produce ‘results’ not through scientific method but through analysis and application to cases. Two prominent examples would be Law and Music Theory, practitioners of which use an established body of theory to solve problems like whether Trinity Western should have a law school or how Scriabin invented the ‘Prometheus chord’. What sense of ‘know’ can we appeal to in order to show that my daughter, who is a music theory student, does not ‘know’ that the Prometheus chord was derived from the over-tone series?

Secondly, there is knowledge about the past that historians uncover through the interpretation of primary documents and other evidence. In what sense do we not ‘know’ that the Weimar Republic fell? This claim is even more remarkable given there are sciences that deal with the past, like Paleontology, which ‘interpret’ signs such as fossils or tools in a manner much more like historians (there is hermeneutic judgment in science which functions no differently than hermeneutic judgment elsewhere).

Thirdly, there is first person knowledge which is direct. “Did that hurt?” asks the doctor because without accepting first-person reportage he cannot proceed with treatment. This is a kind of knowledge without which we could not even do science so that if Strong scientism wants to deny this is knowledge science itself will be the primary victim. Again science can go nowhere without direct factual knowledge (the strip turned green when I put it in water) that is not produced by science but which science itself rests upon.

What about know how? Craftsmen and engineers know all kinds of things by accumulated experience. They know how a shoe is made or what makes for good beer. They also built the Great Wall of China and the Pyramids. What are we to make of disciplines like mathematics, geometry or logic? What about ethical or aesthetic or critical judgments? In what sense does a translator not ‘know’ Japanese? Does anyone really think literature scholars don’t ‘know’ anything about the texts they discuss even on a factual level? What scientific justification does the claim “Marlowe did not write King Lear’ have or even require?  And while we are at it may well be that philosophers do not know much but they do know things like ‘logical positivism fails its own criterion of meaning’ or ‘Berkeley cannot be refuted by kicking a stone’. [5]

It could well be that in regarding all the above as instances of knowledge I am missing something fundamental. If so I wish someone would point it out to me. Let’s take a hypothetical knower, Jill: Jill knows she is feeling cold, knows how to repair watches, knows why the Weimar Republic fell, knows how to speak Portuguese, knows there are 114 Surahs in the Quran, knows how Beethoven transformed the sonata form, has extensive topographical knowledge of places she has travelled, prefers the plays of Shakespeare to those of Thomas Preston, can identify Barbara as valid syllogism, considers racial prejudice indefensible, understands how attorney client privilege applies to the Stormy Daniels affair, can tell an stone age arrowhead from a rock, can comment on the philology of Hebrew, can understand Euclid’s proofs, is engaged in correcting the received text of Finnegans Wake , can explain the Quine/Duhem thesis and its relevance to the question of falsification, has written a commentary on Kant’s third critique and on top of all this is performing experiments in chemistry.

Strong scientism may be correct that only the last endeavour constitutes Jill’s ‘knowledge’ but on what grounds can it defeat what to me looks like the overwhelming presumption that Jill is not just a Chemist who wastes her time at hobbies but a genuine polymath who knows many things in many fields along with all the ordinary knowledge all humans possess?

Problems of Both the Strong and the Weak

The ‘strong scientist’ has surprisingly few options here. Will he point out that science makes true predictions? So have craftsmen for millennia. Further, many of these forms of knowledge do not need to make true predictions: I don’t need to test the hypothesis that there 114 Surahs in the Quran because I know already having checked.[6] Is science more certain of its conclusions? According to the post-Popper consensus at least, scientific statements are always tentative and revisable and in any case first person knowledge so surpasses it in certainty that some of it is arguably infallible. Is science more instrumentally successful?

Craftsmen and hunters kept the species alive for millennia before science even existed in difficult circumstances under which no science would have been possible. What is more some craft knowledge remains instrumentally superior to science to this day: no baseball player chooses a physicist over a batting coach.[7] At any rate success is relative to one’s aims and lawyers successfully produce legal arguments just as philologists successfully solve problems of Homeric grammar.

Now as Aristotle would say science does have the advantage over craft of being explanatory but is explanation unique to science? No; because hermeneutic practices in history, literature, classics and so on also produce explanations of the meaning of things like documents and if the ‘strong scientist’ wants to say that these explanations are tentative and changing (abductions as it were not inductions) then the same is true of a great deal of science. In short, none of the features that supposedly make for the superiority of science are unique to science and some are not even especially exemplified by it. It seems then that there is no criterion by which scientific claims can be shown to be knowledge in a unique and exclusive sense. Until such a criterion is identified it seems to me that my initial presupposition about Jill being a polymath rather than a chemist with distractions stands.   

Perhaps it is the awareness of such difficulties that leads Mizrahi to his stance of ‘Weak Scientism’. It is not a stance he himself entirely sticks to.  Some of his statements imply the strong version of scientism as when he tells us the knowledge is “the scholarly work or research produced in scientific fields of study, such as the natural sciences, as opposed to non-scientific fields, such as the humanities.” (22)[8] Still, when pushed, he seems content with the position that all the things I mentioned above might count as knowledge in a weaker sense but that scientific knowledge is still better and, presumably, more worthy of grants.

Unfortunately, the exact same objections which tell against strong scientism tell against weak scientism too. It is interesting that at this point Mizrahi employs a kind of knowledge I did not discuss above: to defend weak scientism he appeals to the authority of textbooks! (17) These textbooks tell him that science is instrumentally successful, explanatory and makes true predictions. He then tells us that while other disciplines may also betray these traits they do not do so to the same extent so that any money spent on them would be better spent on science on the maxim of prudence (another knowledge form I did not discuss) that one should seek the most bang for one’s buck.

Mizrahi gains little by this move for the question immediately arises better how and at what? Better in what context? By what standard of value? Just take the example of quantity so favored by Mizrahi. Does science produce more knowledge that anything else? Hardly. As Augustine pointed out I can produce a potential infinity of knowledge simply by reflecting recursively on the fact of my own existence. (City of God; XI, 26) Indeed, I can do this by reflecting recursively on my knowledge of ANY fact. Similar recursive processes can extend our knowledge indefinitely in the field of mathematics.

Does science have (taken in bulk) more instrumental success than other knowledge forms? How would you even count given that craft knowledge has a roughly 3 million-year head start? This does not even count the successful record of problem solving in law, politics, or art.[9] Is science more successful at explanation? Hardly, if science could solve problems in literature or history then these fields would not even exist. Science only explains the things it is good at explaining which is no more and no less than one can say of any other discipline. This is why many proponents of scientism tacitly assume that the explanations produced in other disciplines only concern frilly, trivial things that science needn’t bother about anyway.[10]

Does science make more true predictions? Again how would you even count given that for millions of years, human beings survived by making hundreds of true predictions daily? What is more, the inductive procedures of science seem relatively useless in the many endeavours that do not involve true prediction but some other method of justification like deduction or direct observation.

Thus, weak scientism seems in no better a case than strong scientism for the same reasons: there is no clearly applicable, context-independent, criterion that shows the superiority the ‘weak scientist’ claims: certainty, instrumental success, utilitarian value, predictive power and explanation all exist elsewhere in ways that are often not directly commensurable with the way they exist in science. As I told someone once (who asserted the superiority of the French language over all others) French is indeed the best language for speaking French in.[11] Science is the best way to do science.

Why Make Science an Ism at All?

Thus, if Mr. Mizrahi wants a thesis to defend it may well be possible to show that science is at least somewhat better on average at certain things than other approaches. He may call that ‘even weaker’ scientism. This would be to admit after all, that science is superior only in ‘certain relevant aspects’ leaving it to be inferred that it is not superior in others and that the ‘superiority’ that science demonstrates in one context, like particle physics, may vanish in another, like film criticism. If that is what ‘scientism’ amounts to then we are all proponents of it and it is hard to escape the impression that a mountain of argument has given birth to a mouse.

What is more, he informs us: “Brown admits that both scientific and philosophical theories are instruments of explanation. To provide good explanations, then, both scientific and philosophical theories must be testable.” (17) I suppose then it remains open to say that, after all, Joyce scholars ‘test’ their assertions about Ulysses against the text of Ulysses and are to that extent scientists. Perhaps, craftsmen, music theorists, historians and (gasp!) even philosophers, all in their various ways, do likewise: testing their assertions in the ways peculiar to their disciplines. Perhaps, then, all these endeavors are just iterations of science in which case Mirhazi’s mouse has shrunk to something the size of a pygmy shrew.

[1] Does Mirhazi mean to say that if a particular sub-discipline of English produces more articles in a given year than a small subfield of science then that discipline of English is superior to that subfield of science? I’m sure he does not mean to say this but it seems to follow from his words.

[2] The qualitative superiority of science must be based on the value of its goals firstly (like curing disease or discovering alien life) and, secondly, its superiority in achieving those goals over all other methods. The discussion surely assumes that the things done by science must be worth doing more than their opposites. The question has of necessity an axiological component in spite of Mizrahi’s claim to the contrary (9). This means the values of science must be commensurable with the values of non-science if we are to say one is better overall than the other. Not only must science be instrumentally superior at answering scientific questions it must answer the questions of other disciplines better than those disciplines. Otherwise one is simply making the innocuous claim that science answers scientific questions better than geometry or rhetoric can. Mizrahi marshals only one example here: he tells us that the social sciences produce more knowledge about friendship than philosophy does. (19) Of course this assumes that philosophers and social scientists are asking the same or at least commensurable questions about friendship but even if I grant this there are still a vast multitude of instances where this is manifestly not the case, where non-scientists can produce better explanations on non-trivial questions than scientists can. I shall note some of these below.

[3] Mr. Mizrahi might consider, though, whether ideological self-critique might, after all, be a useful way of acquiring self-knowledge (which may not be so contemptible an attainment after all).

[4] This is the ‘Schrodinger’ phenomenon where an antagonist makes two contradictory accusations at once. (https://davewebster.org/2018/02/28/schrodingers-snowflake/) For what seems to be the fons et origo of this narrative see Theocharis and Psimpoulos “Where Science Has Gone Wrong” Nature (1987).

[5] The underlying question here is one of Platonism vs. Aristotelianism. Strong Scientism argues that there is one paradigmatic form of ‘knowledge in itself’. I argue the Aristotelian position that just as ‘being’ is said in many senses (Metaphysics;9, 992b 15) so there are many analogical forms of knowledge. What all the things I have listed have in common is that each in its own peculiar way supports beliefs by appeals to evidence or other forms of justification. Everyday discourse may be wrong to use the word knowledge for these other forms of justified belief but I think the onus is on the ‘strong scientist’ to show this. Another thing I should point out is that I do not confine the word knowledge to beliefs that are indefeasible: a knower might say “to the best of knowledge” and still be a knower. I say this to head off the problem of skepticism which asks whether the criterion of indefeasible knowledge (whatever it is said to be) is ever actually fulfilled. There are valid responses to this problem but consideration of them would take us far afield.

[6] It is silly to imagine me hypothesizing the various numbers of Surahs the Quran could contain before testing my hypothesis by opening the book. Of course, if Mizrahi wishes, I can always put ordinary factual knowledge in the form of a testable proposition. Open War and Peace and you will find it contains an account of the battle of Borodino. Why is a true prediction of this kind any different than a true prediction in science?

[7] Here in fact we get to the nub of the problem. The ultimate problem with scientism weak or strong is that in the real world different knowledge forms interact with each other constantly. Science advances with the help of craftsmen as with the invention of the telescope. Craftsmen make use of science as when a running coach consults a physician. Archeologists and paleontologists employ abduction or hermeneutic reasoning. Art historians call on chemists while biologists call on the local knowledge of indigenous peoples. In a sense there is no such thing as ‘science’ pure and simple as other knowledge forms are inherent to its own structure (even deductive reasoning, the proper province of logicians, is essential to standard accounts of scientific method). This is one reason why, in fact, there is no one superior knowledge form but rather systematic interdependence of ALL knowledge forms.

[8] This is not the only instance of Mizrahi, apparently, trying to use a persuasive definition to win what looks like a mere verbal victory. Of course you can define knowledge as “what the sciences do”, assign another word to “what the humanities do” and go home waving the flag of triumph. But why should any of the rest of take note of such an arbitrary procedure?

[9] Again the problem is that the instrumental success of science rests on the instrumental success of a multitude of other things like the knowledge of bus schedules that gets us to the lab or the social knowledge that allows us to navigate modern institutions. No science tells us how to write a winning grant proposal or informs us that for as longs as Dr. Smith is chief editor of Widgetology the truth about widgets is whatever he says it is. Thus even if we confined the question to the last 50 years it is clear that science cannot claim instrumental superiority over the myriad other anonymous, unmarked processes that make science possible in the first place.

[10] My son, when he was a toddler, ran about the playground proclaiming himself ‘the greatest’. When he failed at any task or challenge he would casually turn to his mother and say “well, the greatest doesn’t do that”! This seems to be the position of many proponents of scientism. If scientists cannot produce good explanations in a field like literature or classics, then it must be that those fields are not really knowledge.

[11] Aristotle made this point ages ago. No inquiry into ethics he tells can have the rigour of geometry any more than the geometer need employ the art of rhetoric. (Nichomachean Ethics; 3, 20,25) Ethics employs phronesis or prudential judgment not logical deduction. Each discipline is answerable to its own internal standards which do not apply outside that discipline. There is, then, no overall ‘super-science’ (like the Platonic dialectic) that embodies a universal method for dealing with all subjects. Aristotle’s world is pluralist, discontinuous and analogical. For this reason, scientists have tended to be Platonists and modern science might be viewed as the revenge of the Platonic/Pythagorean tradition against its wayward pupil. Contemporary philosophy of science, if this author understands it correctly, seems to have restored Aristotelian praxis to the centre of the scientific enterprise. Students of Wittgenstein will no doubt appreciate the point that knowledge comes in as many varieties as games do and there is no more a single account of the first than there is of the second.

In my (2017a), I defend a view I call Weak Scientism, which is the view that knowledge produced by scientific disciplines is better than knowledge produced by non-scientific disciplines.[1] Scientific knowledge can be said to be quantitatively better than non-scientific knowledge insofar as scientific disciplines produce more impactful knowledge–in the form of scholarly publications–than non-scientific disciplines (as measured by research output and research impact). Scientific knowledge can be said to be qualitatively better than non-scientific knowledge insofar as such knowledge is explanatorily, instrumentally, and predictively more successful than non-scientific knowledge.

Brown (2017a) raises several objections against my defense of Weak Scientism and I have replied to his objections (Mizrahi 2017b), thereby showing again that Weak Scientism is a defensible view. Since then, Brown (2017b) has reiterated his objections in another reply on SERRC. Almost unchanged from his previous attack on Weak Scientism (Brown 2017a), Brown’s (2017b) objections are the following:

  1. Weak Scientism is not strong enough to count as scientism.
  2. Advocates of Strong Scientism should not endorse Weak Scientism.
  3. Weak Scientism does not show that philosophy is useless.
  4. My defense of Weak Scientism appeals to controversial philosophical assumptions.
  5. My defense of Weak Scientism is a philosophical argument.
  6. There is nothing wrong with persuasive definitions of scientism.

In what follows, I will respond to these objections, thereby showing once more that Weak Scientism is a defensible view. Since I have been asked to keep this as short as possible, however, I will try to focus on what I take to be new in Brown’s (2017b) latest attack on Weak Scientism.

Is Weak Scientism Strong Enough to Count as Scientism?

Brown (2017b) argues for (1) on the grounds that, on Weak Scientism, “philosophical knowledge may be nearly as valuable as scientific knowledge.” Brown (2017b, 4) goes on to characterize a view he labels “Scientism2,” which he admits is the same view as Strong Scientism, and says that “there is a huge logical gap between Strong Scientism (Scientism2) and Weak Scientism.”

As was the case the first time Brown raised this objection, it is not clear how it is supposed to show that Weak Scientism is not “really” a (weaker) version of scientism (Mizrahi 2017b, 10-11). Of course there is a logical gap between Strong Scientism and Weak Scientism; that is why I distinguish between these two epistemological views. If I am right, Strong Scientism is too strong to be a defensible version of scientism, whereas Weak Scientism is a defensible (weaker) version of scientism (Mizrahi 2017a, 353-354).

Of course Weak Scientism “leaves open the possibility that there is philosophical knowledge” (Brown 2017b, 5). If I am right, such philosophical knowledge would be inferior to scientific knowledge both quantitatively (in terms of research output and research impact) and qualitatively (in terms of explanatory, instrumental, and predictive success) (Mizrahi 2017a, 358).

Brown (2017b, 5) does try to offer a reason “for thinking it strange that Weak Scientism counts as a species of scientism” in his latest attack on Weak Scientism, which does not appear in his previous attack. He invites us to imagine a theist who believes that “modern science is the greatest new intellectual achievement since the fifteenth century” (emphasis in original). Brown then claims that this theist would be an advocate of Weak Scientism because Brown (2017b, 6) takes “modern science is the greatest new intellectual achievement since the fifteenth century” to be “(roughly) equivalent to Weak Scientism.” For Brown (2017b, 6), however, “it seems odd, to say the least, that [this theist] should count as an advocate (even roughly) of scientism.”

Unfortunately, Brown’s appeal to intuition is rather difficult to evaluate because his hypothetical case is under-described.[2] First, the key phrase, namely, “modern science is the greatest new intellectual achievement since the fifteenth century,” is vague in more ways than one. I have no idea what “greatest” is supposed to mean here. Greatest in what respects? What are the other “intellectual achievements” relative to which science is said to be “the greatest”?

Also, what does “intellectual achievement” mean here? There are multiple accounts and literary traditions in history and philosophy of science, science studies, and the like on what counts as “intellectual achievements” or progress in science (Mizrahi 2013b). Without a clear understanding of what these key phrases mean here, it is difficult to tell how Brown’s intuition about this hypothetical case is supposed to be a reason to think that Weak Scientism is not “really” a (weaker) version of scientism.

Toward the end of his discussion of (1), Brown says something that suggests he actually has an issue with the word ‘scientism’. Brown (2017b, 6) writes, “perhaps Mizrahi should coin a new word for the position with respect to scientific knowledge and non-scientific forms of academic knowledge he wants to talk about” (emphasis in original). It should be clear, of course, that it does not matter what label I use for the view that “Of all the knowledge we have, scientific knowledge is the best knowledge” (Mizrahi 2017a, 354; emphasis in original). What matters is the content of the view, not the label.

Whether Brown likes the label or not, Weak Scientism is a (weaker) version of scientism because it is the view that scientific ways of knowing are superior (in certain relevant respects) to non-scientific ways of knowing, whereas Strong Scientism is the view that scientific ways of knowing are the only ways of knowing. As I have pointed out in my previous reply to Brown, whether scientific ways of knowing are superior to non-scientific ways of knowing is essentially what the scientism debate is all about (Mizrahi 2017b, 13).

Before I conclude this discussion of (1), I would like to point out that Brown seems to have misunderstood Weak Scientism. He (2017b, 3) claims that “Weak Scientism is a normative and not a descriptive claim.” This is a mistake. As a thesis (Peels 2017, 11), Weak Scientism is a descriptive claim about scientific knowledge in comparison to non-scientific knowledge. This should be clear provided that we keep in mind what it means to say that scientific knowledge is better than non-scientific knowledge. As I have argued in my (2017a), to say that scientific knowledge is quantitatively better than non-scientific knowledge is to say that there is a lot more scientific knowledge than non-scientific knowledge (as measured by research output) and that the impact of scientific knowledge is greater than that of non-scientific knowledge (as measured by research impact).

To say that scientific knowledge is qualitatively better than non-scientific knowledge is to say that scientific knowledge is explanatorily, instrumentally, and predictively more successful than non-scientific knowledge. All these claims about the superiority of scientific knowledge to non-scientific knowledge are descriptive, not normative, claims. That is to say, Weak Scientism is the view that, as a matter of fact, knowledge produced by scientific fields of study is quantitatively (in terms of research output and research impact) and qualitatively (in terms of explanatory, instrumental, and predictive success) better than knowledge produced by non-scientific fields of study.

Of course, Weak Scientism does have some normative implications. For instance, if scientific knowledge is indeed better than non-scientific knowledge, then, other things being equal, we should give more evidential weight to scientific knowledge than to non-scientific knowledge. For example, suppose that I am considering whether to vaccinate my child or not. On the one hand, I have scientific knowledge in the form of results from clinical trials according to which MMR vaccines are generally safe and effective.

On the other hand, I have knowledge in the form of stories about children who were vaccinated and then began to display symptoms of autism. If Weak Scientism is true, and I want to make a decision based on the best available information, then I should give more evidential weight to the scientific knowledge about MMR vaccines than to the anecdotal knowledge about MMR vaccines simply because the former is scientific (i.e., knowledge obtained by means of the methods of science, such as clinical trials) and the latter is not.

Should Advocates of Strong Scientism Endorse Weak Scientism?

Brown (2017b, 7) argues for (2) on the grounds that “once the advocate of Strong Scientism sees that an advocate of Weak Scientism admits the possibility that there is real knowledge other than what is produced by the natural sciences […] the advocate of Strong Scientism, at least given their philosophical presuppositions, will reject Weak Scientism out of hand.” It is not clear which “philosophical presuppositions” Brown is talking about here. Brown quotes Rosenberg (2011, 20), who claims that physics tells us what reality is like, presumably as an example of a proponent of Strong Scientism who would not endorse Weak Scientism. But it is not clear why Brown thinks that Rosenberg would “reject Weak Scientism out of hand” (Brown 2017d, 7).

Like other proponents of scientism, Rosenberg should endorse Weak Scientism because, unlike Strong Scientism, Weak Scientism is a defensible view. Insofar as we should endorse the view that has the most evidence in its favor, Weak Scientism has more going for it than Strong Scientism does. For to show that Strong Scientism is true, one would have to show that no field of study other than scientific ones can produce knowledge. Of course, that is not easy to show. To show that Weak Scientism is true, one only needs to show that the knowledge produced in scientific fields of study is better (in certain relevant respects) than the knowledge produced in non-scientific fields.

That is precisely what I show in my (2017a). I argue that the knowledge produced in scientific fields is quantitatively better than the knowledge produced in non-scientific fields because there is a lot more scientific knowledge than non-scientific knowledge (as measured by research output) and the former has a greater impact than the latter (as measured by research impact). I also argue that the knowledge produced in scientific fields is qualitatively better than knowledge produced in non-scientific fields because it is more explanatorily, instrumentally, and predictively successful.

Contrary to what Brown (2017b, 7) seems to think, I do not have to show “that there is real knowledge other than scientific knowledge.” To defend Weak Scientism, all I have to show is that scientific knowledge is better (in certain relevant respects) than non-scientific knowledge. If anyone must argue for the claim that there is real knowledge other than scientific knowledge, it is Brown, for he wants to defend the value or usefulness of non-scientific knowledge, specifically, philosophical knowledge.

It is important to emphasize the point about the ways in which scientific knowledge is quantitatively and qualitatively better than non-scientific knowledge because it looks like Brown has confused the two. For he thinks that I justify my quantitative analysis of scholarly publications in scientific and non-scientific fields by “citing the precedent of epistemologists who often treat all items of knowledge as qualitatively the same” (Brown 2017b, 22; emphasis added).

Here Brown fails to carefully distinguish between my claim that scientific knowledge is quantitatively better than non-scientific knowledge and my claim that scientific knowledge is qualitatively better than non-scientific knowledge. For the purposes of a quantitative study of knowledge, information and data scientists can do precisely what epistemologists do and “abstract from various circumstances (by employing variables)” (Brown 2017b, 22) in order to determine which knowledge is quantitatively better.

How Is Weak Scientism Relevant to the Claim that Philosophy Is Useless?

Brown (2017b, 7-8) argues for (3) on the grounds that “Weak Scientism itself implies nothing about the degree to which philosophical knowledge is valuable or useful other than stating scientific knowledge is better than philosophical knowledge” (emphasis in original).

Strictly speaking, Brown is wrong about this because Weak Scientism does imply something about the degree to which scientific knowledge is better than philosophical knowledge. Recall that to say that scientific knowledge is quantitatively better than non-scientific knowledge is to say that scientific fields of study publish more research and that scientific research has greater impact than the research published in non-scientific fields of study.

Contrary to what Brown seems to think, we can say to what degree scientific research is superior to non-scientific research in terms of output and impact. That is precisely what bibliometric indicators like h-index and other metrics are for (Rousseau et al. 2018). Such bibliometric indicators allow us to say how many articles are published in a given field, how many of those published articles are cited, and how many times they are cited. For instance, according to Scimago Journal & Country Rank (2018), which contains data from the Scopus database, of the 3,815 Philosophy articles published in the United States in 2016-2017, approximately 14% are cited, and their h-index is approximately 160.

On the other hand, of the 24,378 Psychology articles published in the United States in 2016-2017, approximately 40% are cited, and their h-index is approximately 640. Contrary to what Brown seems to think, then, we can say to what degree research in Psychology is better than research in Philosophy in terms of research output (i.e., number of publications) and research impact (i.e., number of citations). We can use the same bibliometric indicators and metrics to compare research in other scientific and non-scientific fields of study.

As I have already said in my previous reply to Brown, “Weak Scientism does not entail that philosophy is useless” and “I have no interest in defending the charge that philosophy is useless” (Mizrahi 2017b, 11-12). So, I am not sure why Brown brings up (3) again. Since he insists, however, let me explain why philosophers who are concerned about the charge that philosophy is useless should engage with Weak Scientism as well.

Suppose that a foundation or agency is considering whether to give a substantial grant to one of two projects. The first project is that of a philosopher who will sit in her armchair and contemplate the nature of friendship.[3] The second project is that of a team of social scientists who will conduct a longitudinal study of the effects of friendship on human well-being (e.g., Yang et al. 2016).

If Weak Scientism is true, and the foundation or agency wants to fund the project that is likely to yield better results, then it should give the grant to the team of social scientists rather than to the armchair philosopher simply because the former’s project is scientific, whereas the latter’s is not. This is because the scientific project will more likely yield better knowledge than the non-scientific project will. In other words, unlike the project of the armchair philosopher, the scientific project will probably produce more research (i.e., more publications) that will have a greater impact (i.e., more citations) and the knowledge produced will be explanatorily, instrumentally, and predictively more successful than any knowledge that the philosopher’s project might produce.

This example should really hit home for Brown, since reading his latest attack on Weak Scientism gives one the impression that he thinks of philosophy as a personal, “self-improvement” kind of enterprise, rather than an academic discipline or field of study. For instance, he seems to be saying that philosophy is not in the business of producing “new knowledge” or making “discoveries” (Brown 2017b, 17).

Rather, Brown (2017b, 18) suggests that philosophy “is more about individual intellectual progress rather than collective intellectual progress.” Individual progress or self-improvement is great, of course, but I am not sure that it helps Brown’s case in defense of philosophy against what he sees as “the menace of scientism.” For this line of thinking simply adds fuel to the fire set by those who want to see philosophy burn. As I point out in my (2017a), scientists who dismiss philosophy do so because they find it academically useless.

For instance, Hawking and Mlodinow (2010, 5) write that ‘philosophy is dead’ because it ‘has not kept up with developments in science, particularly physics’ (emphasis added). Similarly, Weinberg (1994, 168) says that, as a working scientist, he ‘finds no help in professional philosophy’ (emphasis added). (Mizrahi 2017a, 356)

Likewise, Richard Feynman is rumored to have said that “philosophy of science is about as useful to scientists as ornithology is to birds” (Kitcher 1998, 32). It is clear, then, that what these scientists complain about is professional or academic philosophy. Accordingly, they would have no problem with anyone who wants to pursue philosophy for the sake of “individual intellectual progress.” But that is not the issue here. Rather, the issue is academic knowledge or research.

Does My Defense of Weak Scientism Appeal to Controversial Philosophical Assumptions?

Brown (2017b, 9) argues for (4) on the grounds that I assume that “we are supposed to privilege empirical (I read Mizrahi’s ‘empirical’ here as ‘experimental/scientific’) evidence over non-empirical evidence.” But that is question-begging, Brown claims, since he takes me to be assuming something like the following: “If the question of whether scientific knowledge is superior to [academic] non-scientific knowledge is a question that one can answer empirically, then, in order to pose a serious challenge to my [Mizrahi’s] defense of Weak Scientism, Brown must come up with more than mere ‘what ifs’” (Mizrahi 2017b, 10; quoted in Brown 2017b, 8).

This objection seems to involve a confusion about how defeasible reasoning and defeating evidence are supposed to work. Given that “a rebutting defeater is evidence which prevents E from justifying belief in H by supporting not-H in a more direct way” (Kelly 2016), claims about what is actual cannot be defeated by mere possibilities, since claims of the form “Possibly, p” do not prevent a piece of evidence from justifying belief in “Actually, p” by supporting “Actually, not-p” directly.

For example, the claim “Hillary Clinton could have been the 45th President of the United States” does not prevent my perceptual and testimonial evidence from justifying my belief in “Donald Trump is the 45th President of the United States,” since the former does not support “It is not the case that Donald Trump is the 45th President of the United States” in a direct way. In general, claims of the form “Possibly, p” are not rebutting defeaters against claims of the form “Actually, p.” Defeating evidence against claims of the form “Actually, p” must be about what is actual (or at least probable), not what is merely possible, in order to support “Actually, not-p” directly.

For this reason, although “the production of some sorts of non-scientific knowledge work may be harder than the production of scientific knowledge” (Brown 2017b, 19), Brown gives no reasons to think that it is actually or probably harder, which is why this possibility does nothing to undermine the claim that scientific knowledge is actually better than non-scientific knowledge. Just as it is possible that philosophical knowledge is harder to produce than scientific knowledge, it is also possible that scientific knowledge is harder to produce than philosophical knowledge. It is also possible that scientific and non-scientific knowledge are equally hard to produce.

Similarly, the possibility that “a little knowledge about the noblest things is more desirable than a lot of knowledge about less noble things” (Brown 2017b, 19), whatever “noble” is supposed to mean here, does not prevent my bibliometric evidence (in terms of research output and research impact) from justifying the belief that scientific knowledge is better than non-scientific knowledge. Just as it is possible that philosophical knowledge is “nobler” (whatever that means) than scientific knowledge, it is also possible that scientific knowledge is “nobler” than philosophical knowledge or that they are equally “noble” (Mizrahi 2017b, 9-10).

In fact, even if Brown (2017a, 47) is right that “philosophy is harder than science” and that “knowing something about human persons–particularly qua embodied rational being–is a nobler piece of knowledge than knowing something about any non-rational object” (Brown 2017b, 21), whatever “noble” is supposed to mean here, it would still be the case that scientific fields produce more knowledge (as measured by research output), and more impactful knowledge (as measured by research impact), than non-scientific disciplines.

So, I am not sure why Brown keeps insisting on mentioning these mere possibilities. He also seems to forget that the natural and social sciences study human persons as well. Even if knowledge about human persons is “nobler” (whatever that means), there is a lot of scientific knowledge about human persons coming from scientific fields, such as anthropology, biology, genetics, medical science, neuroscience, physiology, psychology, and sociology, to name just a few.

One of the alleged “controversial philosophical assumptions” that my defense of Weak Scientism rests on, and that Brown (2017a) complains about the most in his previous attack on Weak Scientism, is my characterization of philosophy as the scholarly work that professional philosophers do. In my previous reply, I argue that Brown is not in a position to complain that this is a “controversial philosophical assumption,” since he rejects my characterization of philosophy as the scholarly work that professional philosophers produce, but he does not tell us what counts as philosophical (Mizrahi 2017b, 13). Well, it turns out that Brown does not reject my characterization of philosophy after all. For, after he was challenged to say what counts as philosophical, he came up with the following “sufficient condition for pieces of writing and discourse that count as philosophy” (Brown 2017b, 11):

(P) Those articles published in philosophical journals and what academics with a Ph.D. in philosophy teach in courses at public universities with titles such as Introduction to Philosophy, Metaphysics, Epistemology, Normative Ethics, and Philosophy of Science (Brown 2017b, 11; emphasis added).

Clearly, this is my characterization of philosophy in terms of the scholarly work that professional philosophers produce. Brown simply adds teaching to it. Since he admits that “scientists teach students too” (Brown 2017b, 18), however, it is not clear how adding teaching to my characterization of philosophy is supposed to support his attack on Weak Scientism. In fact, it may actually undermine his attack on Weak Scientism, since there is a lot more teaching going on in STEM fields than in non-STEM fields.

According to data from the National Center for Education Statistics (2017), in the 2015-16 academic year, post-secondary institutions in the United States conferred only 10,157 Bachelor’s degrees in philosophy and religious studies compared to 113,749 Bachelor’s degrees in biological and biomedical sciences, 106,850 Bachelor’s degrees in engineering, and 117,440 in psychology. In general, in the 2015-2016 academic year, 53.3% of the Bachelor’s degrees conferred by post-secondary institutions in the United States were degrees in STEM fields, whereas only 5.5% of conferred Bachelor’s degrees were in the humanities (Figure 1).

Figure 1. Bachelor’s degrees conferred by post-secondary institutions in the US, by field of study, 2015-2016 (Source: NCES)

 

Clearly, then, there is a lot more teaching going on in science than in philosophy (or even in the humanities in general), since a lot more students take science courses and graduate with degrees in scientific fields of study. So, even if Brown is right that we should include teaching in what counts as philosophy, it is still the case that scientific fields are quantitatively better than non-scientific fields.

Since Brown (2017b, 13) seems to agree that philosophy (at least in part) is the scholarly work that academic philosophers produce, it is peculiar that he complains, without argument, that “an understanding of philosophy and knowledge as operational is […] shallow insofar as philosophy and knowledge can’t fit into the narrow parameters of another empirical study.” Once Brown (2017b, 11) grants that “Those articles published in philosophical journals” count as philosophy, he thereby also grants that these journal articles can be studied empirically using the methods of bibliometrics, information science, or data science.

That is, Brown (2017b, 11) concedes that philosophy consists (at least in part) of “articles published in philosophical journals,” and so these articles can be compared to other articles published in science journals to determine research output, and they can also be compared to articles published in science journals in terms of citation counts to determine research impact. What exactly is “shallow” about that? Brown does not say.

A, perhaps unintended, consequence of Brown’s (P) is that the “great thinkers from the past” (Brown 2017b, 18), those that Brown (2017b, 13) likes to remind us “were not professional philosophers,” did not do philosophy, by Brown’s own lights. For “Socrates, Plato, Augustine, Descartes, Locke, and Hume” (Brown 2017b, 13) did not publish in philosophy journals, were not academics with a Ph.D. in philosophy, and did not teach at public universities courses “with titles such as Introduction to Philosophy, Metaphysics, Epistemology, Normative Ethics, and Philosophy of Science” (Brown 2017b, 11).

Another peculiar thing about Brown’s (P) is the restriction of the philosophical to what is being taught in public universities. What about community colleges and private universities? Is Brown suggesting that philosophy courses taught at private universities do not count as philosophy courses? This is peculiar, especially in light of the fact that, at least according to The Philosophical Gourmet Report (Brogaard and Pynes 2018), the top ranked philosophy programs in the United States are mostly located in private universities, such as New York University and Princeton University.

Is My Defense of Weak Scientism a Scientific or a Philosophical Argument?

Brown argues for (5) on the grounds that my (2017a) is published in a philosophy journal, namely, Social Epistemology, and so it a piece of philosophical knowledge by my lights, since I count as philosophy the research articles that are published in philosophy journals.

Brown would be correct about this if Social Epistemology were a philosophy journal. But it is not. Social Epistemology: A Journal of Knowledge, Culture and Policy is an interdisciplinary journal. The journal’s “aim and scope” statement makes it clear that Social Epistemology is an interdisciplinary journal:

Social Epistemology provides a forum for philosophical and social scientific enquiry that incorporates the work of scholars from a variety of disciplines who share a concern with the production, assessment and validation of knowledge. The journal covers both empirical research into the origination and transmission of knowledge and normative considerations which arise as such research is implemented, serving as a guide for directing contemporary knowledge enterprises (Social Epistemology 2018).

The fact that Social Epistemology is an interdisciplinary journal, with contributions from “Philosophers, sociologists, psychologists, cultural historians, social studies of science researchers, [and] educators” (Social Epistemology 2018) would not surprise anyone who is familiar with the history of the journal. The founding editor of the journal is Steve Fuller, who was trained in an interdisciplinary field, namely, History and Philosophy of Science (HPS), and is currently the Auguste Comte Chair in Social Epistemology in the Department of Sociology at Warwick University. Brown (2017b, 15) would surely agree that sociology is not philosophy, given that, for him, “cataloguing what a certain group of people believes is sociology and not philosophy.” The current executive editor of the journal is James H. Collier, who is a professor of Science and Technology in Society at Virginia Tech, and who was trained in Science and Technology Studies (STS), which is an interdisciplinary field as well.

Brown asserts without argument that the methods of a scientific field of study, such as sociology, are different in kind from those of philosophy: “What I contend is that […] philosophical methods are different in kind from those of the experimental scientists [sciences?]” (Brown 2017b, 24). He then goes on to speculate about what it means to say that an explanation is testable (Brown 2017b, 25). What Brown comes up with is rather unclear to me. For instance, I have no idea what it means to evaluate an explanation by inductive generalization (Brown 2017b, 25).

Instead, Brown should have consulted any one of the logic and reasoning textbooks I keep referring to in my (2017a) and (2017b) to find out that it is generally accepted among philosophers that the good-making properties of explanations, philosophical and otherwise, include testability among other good-making properties (see, e.g., Sinnott-Armstrong and Fogelin 2010, 257). As far as testability is concerned, to test an explanation or hypothesis is to determine “whether predictions that follow from it are true” (Salmon 2013, 255). In other words, “To say that a hypothesis is testable is at least to say that some prediction made on the basis of that hypothesis may confirm or disconfirm it” (Copi et al. 2011, 515).

For this reason, Feser’s analogy according to which “to compare the epistemic values of science and philosophy and fault philosophy for not being good at making testable predications [sic] is like comparing metal detectors and gardening tools and concluding gardening tools are not as good as metal detectors because gardening tools do not allow us to successfully detect for metal” (Brown 2017b, 25), which Brown likes to refer to (Brown 2017a, 48), is inapt.

It is not an apt analogy because, unlike metal detectors and gardening tools, which serve different purposes, both science and philosophy are in the business of explaining things. Indeed, Brown admits that, like good scientific explanations, “good philosophical theories explain things” (emphasis in original). In other words, Brown admits that both scientific and philosophical theories are instruments of explanation (unlike gardening and metal-detecting instruments). To provide good explanations, then, both scientific and philosophical theories must be testable (Mizrahi 2017b, 19-20).

What Is Wrong with Persuasive Definitions of Scientism?

Brown (2017b, 31) argues for (6) on the grounds that “persuasive definitions are [not] always dialectically pernicious.” He offers an argument whose conclusion is “abortion is murder” as an example of an argument for a persuasive definition of abortion. He then outlines an argument for a persuasive definition of scientism according to which “Weak Scientism is a view that has its advocates putting too high a value on scientific knowledge” (Brown 2017b, 32).

The problem, however, is that Brown is confounding arguments for a definition with the definition itself. Having an argument for a persuasive definition does not change the fact that it is a persuasive definition. To illustrate this point, let me give an example that I think Brown will appreciate. Suppose I define theism as an irrational belief in the existence of God. That is, “theism” means “an irrational belief in the existence of God.” I can also provide an argument for this definition:

P1: If it is irrational to have paradoxical beliefs and God is a paradoxical being, then theism is an irrational belief in the existence of God.

P2: It is irrational to have paradoxical beliefs and God is a paradoxical being (e.g., the omnipotence paradox).[4]

Therefore,

C: Theism is an irrational belief in the existence of God.

But surely, theists will complain that my definition of theism is a “dialectically pernicious” persuasive definition. For it stacks the deck against theists. It states that theists are already making a mistake, by definition, simply by believing in the existence of God. Even though I have provided an argument for this persuasive definition of theism, my definition is still a persuasive definition of theism, and my argument is unlikely to convince anyone who doesn’t already think that theism is irrational. Indeed, Brown (2017b, 30) himself admits that much when he says “good luck with that project!” about trying to construct a sound argument for “abortion is murder.” I take this to mean that pro-choice advocates would find his argument for “abortion is murder” dialectically inert precisely because it defines abortion in a manner that transfers “emotive force” (Salmon 2013, 65), which they cannot accept.

Likewise, theists would find the argument above dialectically inert precisely because it defines theism in a manner that transfers “emotive force” (Salmon 2013, 65), which they cannot accept. In other words, Brown seems to agree that there are good dialectical reasons to avoid appealing to persuasive definitions. Therefore, like “abortion is murder,” “theism is an irrational belief in the existence of God,” and “‘Homosexual’ means ‘one who has an unnatural desire for those of the same sex’” (Salmon 2013, 65), “Weak Scientism is a view that has its advocates putting too high a value on scientific knowledge” (Brown 2017b, 32) is a “dialectically pernicious” persuasive definition (cf. Williams 2015, 14).

Like persuasive definitions in general, it “masquerades as an honest assignment of meaning to a term while condemning or blessing with approval the subject matter of the definiendum” (Hurley 2015, 101). As I have pointed out in my (2017a), the problem with such definitions is that they “are strategies consisting in presupposing an unaccepted definition, taking a new unknowable description of meaning as if it were commonly shared” (Macagno and Walton 2014, 205).

As for Brown’s argument for the persuasive definition of Weak Scientism, according to which it “is a view that has its advocates putting too high a value on scientific knowledge” (Brown 2017b, 32), a key premise in this argument is the claim that there is a piece of philosophical knowledge that is better than scientific knowledge. This is premise 36 in Brown’s argument:

Some philosophers qua philosophers know that (a) true friendship is a necessary condition for human flourishing and (b) the possession of the moral virtues or a life project aimed at developing the moral virtues is a necessary condition for true friendship and (c) (therefore) the possession of the moral virtues or a life project aimed at developing the moral virtues is a necessary condition for human flourishing (see, e.g., the arguments in Plato’s Gorgias) and knowledge concerning the necessary conditions of human flourishing is better than any sort of scientific knowledge (see, e.g., St. Augustine’s Confessions, book five, chapters iii and iv) [assumption]

There is a lot to unpack here, but I will focus on what I take to be the points most relevant to the scientism debate. First, Brown assumes 36 without argument, but why think it is true? In particular, why think that (a), (b), and (c) count as philosophical knowledge? Brown says that philosophers know (a), (b), and (c) in virtue of being philosophers, but he does not tell us why that is the case.

After all, accounts of friendship, with lessons about the significance of friendship, predate philosophy (see, e.g., the friendship of Gilgamesh and Enkidu in The Epic of Gilgamesh). Did it really take Plato and Augustine to tell us about the significance of friendship? In fact, on Brown’s characterization of philosophy, namely, (P), (a), (b), and (c) do not count as philosophical knowledge at all, since Plato and Augustine did not publish in philosophy journals, were not academics with a Ph.D. in philosophy, and did not teach at public universities courses “with titles such as Introduction to Philosophy, Metaphysics, Epistemology, Normative Ethics, and Philosophy of Science” (Brown 2017b, 11).

Second, some philosophers, like Epicurus, need (and think that others need) friends to flourish, whereas others, like Diogenes of Sinope, need no one. For Diogenes, friends will only interrupt his sunbathing (Arrian VII.2). My point is not simply that philosophers disagree about the value of friendship and human flourishing. Of course they disagree.[5]

Rather, my point is that, in order to establish general truths about human beings, such as “Human beings need friends to flourish,” one must employ the methods of science, such as randomization and sampling procedures, blinding protocols, methods of statistical analysis, and the like; otherwise, one would simply commit the fallacies of cherry-picking anecdotal evidence and hasty generalization (Salmon 2013, 149-151). After all, the claim “Some need friends to flourish” does not necessitate, or even make more probable, the truth of “Human beings need friends to flourish.”[6]

Third, why think that “knowledge concerning the necessary conditions of human flourishing is better than any sort of scientific knowledge” (Brown 2017b, 32)? Better in what sense? Quantitatively? Qualitatively? Brown does not tell us. He simply declares it “self-evident” (Brown 2017b, 32). I take it that Brown would not want to argue that “knowledge concerning the necessary conditions of human flourishing” is better than scientific knowledge in the quantitative (i.e., in terms of research output and research impact) and qualitative (i.e., in terms of explanatory, instrumental, and predictive success) respects in which scientific knowledge is better than non-scientific knowledge, according to Weak Scientism.

If so, then in what sense exactly “knowledge concerning the necessary conditions of human flourishing” (Brown 2017b, 32) is supposed to be better than scientific knowledge? Brown (2017b, 32) simply assumes that without argument and without telling us in what sense exactly “knowledge concerning the necessary conditions of human flourishing is better than any sort of scientific knowledge” (Brown 2017b, 32).

Of course, philosophy does not have a monopoly on friendship and human flourishing as research topics. Psychologists and sociologists, among other scientists, work on friendship as well (see, e.g., Hojjat and Moyer 2017). To get an idea of how much research on friendship is done in scientific fields, such as psychology and sociology, and how much is done in philosophy, we can use a database like Web of Science.

Currently (03/29/2018), there are 12,334 records in Web of Science on the topic “friendship.” Only 76 of these records (0.61%) are from the Philosophy research area. Most of the records are from the Psychology (5,331 records) and Sociology (1,111) research areas (43.22% and 9%, respectively). As we can see from Figure 2, most of the research on friendship is done in scientific fields of study, such as psychology, sociology, and other social sciences.

Figure 2. Number of records on the topic “friendship” in Web of Science by research area (Source: Web of Science)

 

In terms of research impact, too, scientific knowledge about friendship is superior to philosophical knowledge about friendship. According to Web of Science, the average citations per year for Psychology research articles on the topic of friendship is 2826.11 (h-index is 148 and the average citations per item is 28.1), and the average citations per year for Sociology research articles on the topic of friendship is 644.10 (h-index is 86 and the average citations per item is 30.15), whereas the average citations per year for Philosophy research articles on friendship is 15.02 (h-index is 13 and the average citations per item is 8.11).

Quantitatively, then, psychological and sociological knowledge on friendship is better than philosophical knowledge in terms of research output and research impact. Both Psychology and Sociology produce significantly more research on friendship than Philosophy does, and the research they produce has significantly more impact (as measured by citation counts) than philosophical research on the same topic.

Qualitatively, too, psychological and sociological knowledge about friendship is better than philosophical knowledge about friendship. For, instead of rather vague statements about how “true friendship is a necessary condition for human flourishing” (Brown 2017b, 32) that are based on mostly armchair speculation, psychological and sociological research on friendship provides detailed explanations and accurate predictions about the effects of friendship (or lack thereof) on human well-being.

For instance, numerous studies provide evidence for the effects of friendships or lack of friendships on physical well-being (see, e.g., Yang et al. 2016) as well as mental well-being (see, e.g., Cacioppo and Patrick 2008). Further studies provide explanations for the biological and genetic bases of these effects (Cole et al. 2011). This knowledge, in turn, informs interventions designed to help people deal with loneliness and social isolation (see, e.g., Masi et al. 2010).[7]

To sum up, Brown (2017b, 32) has given no reasons to think that “knowledge concerning the necessary conditions of human flourishing is better than any sort of scientific knowledge.” He does not even tell us what “better” is supposed to mean here. He also ignores the fact that scientific fields of study, such as psychology and sociology, produce plenty of knowledge about human flourishing, both physical and mental well-being. In fact, as we have seen, science produces a lot more knowledge about topics related to human well-being, such as friendship, than philosophy does. For this reason, Brown (2017b, 32) has failed to show that “there is non-scientific form of knowledge better than scientific knowledge.”

Conclusion

At this point, I think it is quite clear that Brown and I are talking past each other on a couple of levels. First, I follow scientists (e.g., Weinberg 1994, 166-190) and philosophers (e.g., Haack 2007, 17-18 and Peels 2016, 2462) on both sides of the scientism debate in treating philosophy as an academic discipline or field of study, whereas Brown (2017b, 18) insists on thinking about philosophy as a personal activity of “individual intellectual progress.” Second, I follow scientists (e.g., Hawking and Mlodinow 2010, 5) and philosophers (e.g., Kidd 2016, 12-13 and Rosenberg 2011, 307) on both sides of the scientism debate in thinking about knowledge as the scholarly work or research produced in scientific fields of study, such as the natural sciences, as opposed to non-scientific fields of study, such as the humanities, whereas Brown insists on thinking about philosophical knowledge as personal knowledge.

To anyone who wishes to defend philosophy’s place in research universities alongside academic disciplines, such as history, linguistics, and physics, armed with this conception of philosophy as a “self-improvement” activity, I would use Brown’s (2017b, 30) words to say, “good luck with that project!” A much more promising strategy, I propose, is for philosophy to embrace scientific ways of knowing and for philosophers to incorporate scientific methods into their research.[8]

Revisiting an Objection to Mizrahi’s Attempt to Defeat Objection O2

Recall that Mizrahi thinks Mizrahi’s Argument is a scientific argument. Furthermore, in 2017a he thinks he needs to defend Weak Scientism against objection O2. He does so by arguing that: (a) if O2 is true, then all knowledge by inference would be viciously circular; but the consequent of (a) is false, and, therefore, the antecedent of (a) is false.

In my 2017 response to Mizrahi 2017a, I argued that Mizrahi’s attempt to defeat objection O2 fails since he assumes, citing Ladyman, that “‘deductive inference is only defensible by appeal to deductive inference’ (Ladyman 2002, 49)” (Mizrahi 2017a, 362) whereas it is reasonable to think that the rules of deductive inference are defensible by noting we believe them by the same sort of power we believe propositions such as ‘1+1=2’ and ‘a whole is greater than one its parts’, namely, some non-inferential mode of knowing (see, e.g., Feldman 2003, 3-4). So there is no inconsistency in affirming both a scientific argument for Weak Scientism is a circular argument and knowledge of the rules of deductive inference is defensible.

Now, in responding to my comment in 2017, Mizrahi misconstrues my comment by rendering it as the following question: “why think that deductive rules of inference cannot be proved valid in a non-circular way?” (2017b, 9; emphasis mine). But as should be clear from the above, this is not my objection, since I never talk about “proving in a valid way” deductive rules of inference. Mizrahi seems to think that the only way to show deductive inference is defensible is by way of a circular proof of them. But why think a thing like that? Rather, as Aristotle famously points out, good deductive arguments have to start from premises that we know with certainty by way of some non-deductive means (Posterior Analytics, Book II, ch. 19, see esp. 100a14-100b18). Again, Mizrahi has not shown there is an inconsistency in affirming both a scientific argument for Weak Scientism is a circular argument and knowledge of the rules of deductive inference is defensible.

Against Mizrahi’s Claim that Philosophers Should Not Use Persuasive Definitions of Scientism.

In 2017a, Mizrahi claims that persuasive definitions of scientism, e.g., “scientism is a matter of putting too high a value on science in comparison with other branches of learning or culture” (Sorrell 1994, x) or “scientism is an exaggerated deference towards science, an excessive readiness to accept as authoritative any claim made by the sciences, and to dismiss every kind of criticism of science or its practitioners as anti-scientific prejudice” (Haack 2007, 17-18), are problematic because they beg the question against the scientistic stance (Mizrahi 2017a, 351; 352), or otherwise err by not “show[ing] precisely what is wrong with scientism” (2017a, 352).

In my 2017 response to Mizrahi’s claim that philosophers should not use persuasive definitions of scientism, I do two things. First, I offer a counter-example to Mizrahi’s view by showing that one can give a logically valid argument for the “persuasive” description, ‘abortion is murder’, an argument that does not beg questions against those who deny the conclusion and also explains why some folks accept the conclusion. Second, I attempted to offer a non-question begging argument for a persuasive description of scientism, one which offers an explanation—by way of its premises—why someone may accept that definition as true.

Mizrahi offers some objections to my 2017 response on this score. First, Mizrahi objects that my sample argument for the conclusion, abortion is murder, is invalid. He next posits that one of the premises of my sample argument for the conclusion, abortion is murder, is such that “the emotionally charged term ‘innocent’ is smuggled into [it]” (2017b, 18). Finally, he gives a reason why one may think the premise, the human fetus is an innocent person, is false.

Mizrahi thinks my argument for a persuasive definition of scientism “suffers from the same problems as [my] abortion argument” (2017b, 18). More specifically, he thinks the argument is “misleading” since it treats Strong Scientism and Weak Scientism in one argument and Mizrahi does not advocate for Strong Scientism, but for Weak Scientism. In addition, he notes I assume “without argument that there is some item of knowledge . . . that is both non-scientific and better than scientific knowledge. Given that the scientism debate is precisely about whether scientific knowledge is superior to non-scientific knowledge, one cannot simply assume that non-scientific knowledge is better than scientific knowledge without begging the question” (2017b, 19).

In responding to these objections, I begin with Mizrahi’s analysis of my sample argument for the conclusion, abortion is murder. The first thing to say is that Mizrahi criticizes an argument different from the one I give in my 2017 response. The sample argument I offer in 2017 is as follows:

14. Abortion is the direct killing of a human fetus.
15. The human fetus is an innocent person.
16. Therefore, abortion is the direct killing of an innocent person [from 14 and 15].
17. The direct killing of an innocent person is murder.
18. Therefore, abortion is murder [from 16 and 17].

For some reason, Mizrahi renders premise 14 as

14a. Abortion is the direct killing of a human being (2017b, 17).

Mizrahi then accuses me of offering an invalid argument. Now, I agree that an argument the conclusion of which is proposition 16 and the premises of which are 14a and 15 is a logically invalid argument. But my argument has 16 as its conclusion and 14 and 15 as its premises, and that argument is logically valid.

As for Mizrahi’s next objection to my sample argument for the conclusion, abortion is murder, just because a person S finds a premise “emotionally charged” does not mean a person S1 can’t properly use that premise in an argument; that is to say, just because some person S doesn’t like to consider whether a premise is true, or doesn’t like to think about the implications of a premise’s being true, it does not follow that the use of such a premise is somehow dialectically improper.

If it were the case that emotionally laden or emotionally charged premises are off-limits, then just about all arguments in applied ethics (about topics such as the morality of the death penalty, eating meat, factory farming, gun-control, etc.) would be problematic since such arguments regularly employ premises that advocates and opponents alike will find emotionally laden or emotionally charged. The claim that a premise is dialectically improper because it is emotionally laden or emotionally charged is a non-starter.

Perhaps Mizrahi would counter by saying premise 15 is itself a persuasive definition or description, and so to use it as a premise in an argument that is supposed to be a counter-example to the view that the use of persuasive definitions is question-begging is itself question-begging. In that case, one may add the following premises to my sample argument for a non-question-begging argument that explains why someone may think abortion is murder:

15a. If a human person has not committed any crimes and is not intentionally attacking a human person, then that human person is an innocent person [assumption].

15b. A human being is a human person [assumption].

15c. A human fetus is a human being [assumption].

15d. Therefore, a human fetus is a human person [from 15b and 15c]

15e. Therefore, if a human fetus has not committed any crimes and is not intentionally attacking a human person, then a human fetus is an innocent person [from 15a and 15d].

15f. A human fetus has not committed any crimes and is not intentionally attacking a human person [assumption].

15g. Therefore, a human fetus is an innocent person [from 15e and 15f, MP].

Now, it may be that Mizrahi will offer reasons for rejecting some of the premises in the argument above, just as he offers a reason in 2017a for thinking 15 is false in the argument consisting of propositions 14-18. But all that would be beside the point. For the goal was not to produce a sample argument whose conclusion was a persuasive definition or description that any philosopher would think is sound—good luck with that project!—but rather to produce a logically valid argument for a persuasive definition of a term that both (a) does not beg any questions against those who reject the conclusion and (b) provides reasons for thinking the conclusion is true. But both the argument consisting of propositions 14-18 and the argument consisting of propositions 15a-15g do just that. Therefore, these arguments constitute good counter-examples to Mizrahi’s claim that persuasive definitions are always dialectally pernicious.

Turning to my argument in defense of a persuasive definition of scientism, I grant that my attempt in 2017 to offer one argument in defense of a persuasive definition of scientism that makes reference both to Strong Scientism and Weak Scientism is misleading. I therefore offer here an argument for a persuasive definition of Weak Scientism.
Also, rather than using variables in my sample argument, which I thought sufficient in my 2017 response (for the simple reason I thought a sample schema for a non-question begging argument in defense of a persuasive definition of scientism is what was called for), I also offer a possible example of a piece of philosophical knowledge that is better than scientific knowledge in my argument here. In my view, the following logically valid argument both offers an explanation for accepting its conclusion and does not beg any questions against those who reject its conclusion:

  1. Weak Scientism is the view that, of the various kinds of knowledge, scientific knowledge is the best [assumption].
  2. If scientific knowledge is the best kind of knowledge, then scientific knowledge is better than all forms of non-scientific knowledge [self-evident].
  3. Weak Scientism implies scientific knowledge is better than all forms of non-scientific knowledge [from 28 and 29].
  4. If position P1 implies that x is better than all forms of non-x, then P1 implies x is more valuable than all forms of non-x [assumption].[1]
  5. Therefore, Weak Scientism implies scientific knowledge is more valuable than all forms of non-scientific knowledge [from 30 and 31].
  6. If position P1 implies that x is more valuable than all forms of non-x, but x is not more valuable than all forms of non-x, then P1 is a view that has its advocates putting too high a value on x [assumption].
  7. Therefore, if Weak Scientism implies that scientific knowledge is more valuable than all forms of non-scientific knowledge and scientific knowledge is not more valuable than all forms of non-scientific knowledge, then Weak Scientism is a view that has its advocates putting too high a value on scientific knowledge [from 33].
  8. Some philosophers qua philosophers know that (a) true friendship is a necessary condition for human flourishing and (b) the possession of the moral virtues or a life project aimed at developing the moral virtues is a necessary condition for true friendship and (c) (therefore) the possession of the moral virtues or a life project aimed at developing the moral virtues is a necessary condition for human flourishing (see, e.g., the argument in Plato’s Gorgias[2]) and knowledge concerning the necessary conditions of human flourishing is better than any sort of scientific knowledge (see, e.g., St. Augustine’s Confessions, book five, chapters iii and iv), then there is a non-scientific form of knowledge better than scientific knowledge [self-evident].
  9. Some philosophers qua philosophers know that (a) true friendship is a necessary condition for human flourishing and (b) the possession of the moral virtues or a life project aimed at developing the moral virtues is a necessary condition for true friendship and (c) (therefore) the possession of the moral virtues or a life project aimed at developing the moral virtues is a necessary condition for human flourishing (see, e.g., the argument in Plato’s Gorgias) and knowledge concerning the necessary conditions of human flourishing is better than any sort of scientific knowledge (see, e.g., St. Augustine’s Confessions, book five, chapters iii and iv) [assumption].
  10. Therefore, there is a form of non-scientific knowledge better than scientific knowledge [from 35 and 36, MP].
  11. If knowing some form of non-x is better than knowing x, then knowing some form of non-x is more valuable than knowing x [assumption].
  12. Therefore, there is a form of non-scientific knowledge that is more valuable than scientific knowledge [from 37 and 38].
  13. Therefore, scientific knowledge is not more valuable than all forms of non-scientific knowledge [from 39].
  14. Therefore, Weak Scientism is a view that has its advocates putting too high a value on scientific knowledge [from 34, 32, and 40, MP].

In my view, the argument above both offers an explanation for accepting its conclusion and does not beg any questions against those who reject the conclusion. Someone may think one of the premises is false, e.g., 36. But that is beside the point at issue here. For Mizrahi claims the use of persuasive definitions always involves begging the question or a failure to support the persuasive definition with reasons.

But the argument above does not beg the question; someone may think Weak Scientism is true, become acquainted with the claim in premise 36, and then, realizing the error of his ways by way of the argument above, reject Weak Scientism. The argument above also provides a set of reasons for the conclusion, which is a persuasive description of Weak Scientism. It therefore constitutes a good counter-example to Mizrahi’s claim that the use of a persuasive definition of scientism is always problematic.

Problems for Mizrahi’s Argument, Given the Number and Kind of Philosophical Assumptions at Play in the Argument

In his 2017b response, Mizrahi makes some general criticisms of my strategy in criticizing Mizrahi’s Argument as well as offering particular objections to particular arguments I make in my 2017 essay with respect to Mizrahi’s Argument. In response, then, I first say a few things about Mizrahi’s general criticisms. Second, I respond to Mizrahi’s particular objections.

Mizrahi’s first general criticism of my approach is that I simply criticize Mizrahi’s Argument by proposing certain “what ifs?” (2017b, 9). His objection seems to be the following:

  1. “The question of whether scientific knowledge is superior to non-scientific [academic] knowledge is a question that can be answered empirically” (2017b, 10).
  2. “Therefore, in order to pose a serious challenge to my defense of Weak Scientism, Brown must come up with more than mere ‘what ifs’” (2017b, 10).

The argument is clearly an enthymeme. Mizrahi presumably is presupposing:

  1. If the question of whether scientific knowledge is superior to non-scientific [academic] knowledge is a question that one can answer empirically, then, in order to pose a serious challenge to my defense of Weak Scientism, Brown must come up with more than mere “what ifs” [assumption].

But why accept 27? Presumably because we are supposed to privilege empirical (I read Mizrahi’s ‘empirical’ here as ‘experimental/scientific’) evidence over non-empirical evidence. But that’s just assuming the sort of thing that is at issue when debating the truth or falsity of scientism. So Mizrahi’s response here begs the question against those who raise critical questions about Mizrahi’s Argument and Weak Scientism.

In addition, premise 25 is one of the propositions up for debate here. Mizrahi thinks Mizrahi’s Argument is a scientific argument. I disagree, for reasons stated in my 2017 article (more on this below).

A second general criticism Mizrahi raises for my critique of Mizrahi’s Argument concerns my habit of speaking about “controversial philosophical assumptions” at play in Mizrahi’s Argument. First, Mizrahi does not like my use of the word ‘assumptions’ in reference to the (implied) premises of Mizrahi’s Argument (2017b, 12; 14) since, according to Mizrahi, “an assumption is a statement that is taken to be true without justification or support.”

I just have to confess that I don’t think ‘assumption’ necessarily has this connotation. I certainly did not intend to communicate in every case I use the word ‘assumption’ in my 2017 article that Mizrahi had not supplied any justification or support for such propositions (although I do think it is the case that Mizrahi does not offer justification for some of the [implied] premises in Mizrahi’s Argument). For better or for worse (probably worse) I was thinking of ‘assumption’ as a synonym of ‘stipulation’ or ‘presupposition’ or ‘premise.’ But I will try to be more precise in what follows.

Second, Mizrahi takes me to task for calling the (implied) premises of Mizrahi’s Argument controversial, since I don’t say why they are controversial and, as Mizrahi states with respect to his 2017a, “the way I have characterized knowledge is exactly the way others in the scientism debate understand knowledge (see, e.g., Peels 2016, 2462), which means that my characterization of knowledge is not controversial as far as the scientism debate in philosophy is concerned” (2017b, 13; see also 14-15).  In addition, by calling a premise ‘controversial’, Mizrahi takes me to mean that I am saying it is doubtful (2017b, 14-15), which, if true, would raise some puzzles for my own responses to Mizrahi 2017a.

In response, my comment in 2017 that the (implied) premises in Mizrahi’s Argument are controversial was neither intended as commentary on a narrow philosophical discussion—what Mizrahi calls “the scientism debate in philosophy” (2017b, 13; emphasis mine)—nor meant simply to point out that it is possible to doubt those premises (Mizrahi 2017b, 14-15). Rather, what I intended to say (and should have made clearer) is that the (implied) premises of Mizrahi’s Argument are controversial when we contrast them with the views of a number of different philosophical schools of thought.

That is to say, I meant to suggest that a healthy minority of contemporary philosophers will reject those premises, and have reasons for rejecting them, where that healthy minority consists (just to name a few schools of thought that have contemporary adherents) of some Platonists, Aristotelians, neo-Aristotelians, Augustinians, Thomists, Scotists, Suarezians, Ockhamists, Cartesians, Liebnizians, Kantians, neo-Kantians of various sorts, Phenomenologists, Existentialists, Whiteheadians, as well as quite a few non-naturalist analytic philosophers.

Indeed, if we practice “the democracy of the dead,” as G. K. Chesterton suggested is only fair,[1] the majority of philosophers in the past would reject the implied premises in Mizrahi’s Argument; or, if that’s a bit anachronistic, they would reject premises at least analogous to those in Mizrahi’s Argument insofar as they would not reduce philosophical knowledge to what professional philosophers make public; think of, to take just one example, Plato’s criticism of the professional philosophers of his day as false philosophers in the Phaedo[2] and the Republic.[3]

Of course, there are non-philosophers too, including practicing natural scientists (past and present) who (would) also reject Weak Scientism and many of the (implied) premises in Mizrahi’s Argument. One gets the impression from both 2017a and 2017b that Mizrahi does not think Mizrahi’s Argument is at all controversial. It was for these reasons and in the sense specified here that I emphasized in my 2017 response that a number of (implied) premises in Mizrahi’s Argument are, in fact, very controversial.

In addition, Mizrahi himself cites contemporary philosophers engaged in “the scientism debate in philosophy” who reject Mizrahi’s reduction of philosophy and philosophical knowledge to what philosophers publish (see, e.g., Sorrell 1994 and Haack 2017). There are other professional philosophers engaged in debates about the plausibility of scientism who reject quite a few of the premises in Mizrahi’s Argument (see, e.g., Brown 2011, the authors of some of the papers in Williams & Robinson 2015, and the work of analytic philosopher, Edward Feser, who has offered criticisms of scientism in: 2008, 83-85; 2010a; 2010b, and 2014, 9-24).

Third, Mizrahi thinks I should not call his assumptions philosophical unless I have first defined ‘philosophy’ (2017b, 13; 14), particularly since I claim that his argument is a philosophical and not a scientific argument (2017b, 9; 15). He states: “what Brown labels as ‘philosophical’ is not really philosophical, or at least he is not in a positon to claim that it is philosophical, since he does not tell us what makes something philosophical (other than being work produced by professional philosophers, which is a characterization of ‘philosophical’ that he rejects)” (2017b, 14).

I do not define the nature of philosophy in my 2017 response to Mizrahi’s 2017a. I supposed, perhaps wrongly, that such an endeavor was altogether outside the scope of the project of offering some critical comments on a philosophy paper. Of course, as Mizrahi no doubt knows, even the greatest of Greek philosophers, e.g., Socrates, Plato, and Aristotle, all think about philosophy in very different ways (for Socrates philosophy is a way of life which consists of a search for wisdom; for Plato philosophy is not only a search for wisdom but also involves the possession of wisdom, if only by way of the recollection of an other-worldly (or pre-worldly) set of experiences; Aristotle thinks philosophy is said in many ways (hence metaphysics is ‘first philosophy’), but pace Plato, successful philosophy, Aristotle thinks, needs to make sense of what we know by common sense).

St. Augustine has yet a different way of thinking about the nature of philosophy (philosophy is the search for wisdom, but such a search need not be limited to a mere human investigation, as with the Greeks; it may be that wisdom can be found in a rational reception of a divine revelation). By the time we get to the twentieth century there is also the great divide between analytic and continental approaches to philosophy. As Mizrahi points out, philosophers today disagree with one another about the nature of philosophy (2017a, 356).

So I could give an account of how I understand the philosophical enterprise, but that account itself would be controversial, and beside the point.[4] Perhaps, if only for dialectical purposes, we can give the following as a sufficient condition for pieces of writing and discourse that count as philosophy (N.B. philosophy, not good philosophy):

(P) Those articles published in philosophical journals and what academics with a Ph.D. in philosophy teach in courses at public universities with titles such as Introduction to Philosophy, Metaphysics, Epistemology, Normative Ethics, and Philosophy of Science.

Whereas Mizrahi takes the reduction of philosophy to what professional philosophers publish in academic journals as a premise in Mizrahi’s Argument, I don’t take P to be a necessary condition for something’s counting as philosophy. For philosophical discourses are also recorded, for example, in old books, some of which are not typically taught in philosophy courses today, and (some very good) philosophy, productive of philosophical knowledge, also occurs in conversations between persons who can directly see and hear one another. Indeed, some persons who do not have a Ph.D. in philosophy do (good) philosophy too.

First Controversial Philosophical Premise in Mizrahi’s Argument

Having remarked on Mizrahi’s general criticisms of my objections to Mizrahi’s Argument, I now turn to addressing Mizrahi’s objections to the particular objections or points I make in my critique of Mizrahi’s Argument in 2017. I address these objections not in the order Mizrahi raises them in 2017b, but as these objections track with the objections I raise in my 2017 article, and in the order I raise them (Mizrahi does not comment upon what I call ‘the Second Assumption’ at play in Mizrahi’s Argument in his 2017b, and so I say nothing else about it here).

Recall that the general schema for Mizrahi’s Argument is the following:

  1. One kind of knowledge is better than another quantitatively or qualitatively [assumption].
    8. Scientific knowledge is quantitatively better than non-scientific knowledge (including philosophical knowledge) in terms of the number of journal articles published and the number of journal articles cited.
    9. Scientific knowledge is qualitatively better than non-scientific knowledge (including philosophical knowledge) insofar as scientific theories are more successful than non-scientific theories (including philosophical theories) where the success of a theory is understood in terms of its explanatory, instrumental, and predictive success.
    10. Therefore, scientific knowledge is better than non-scientific forms of knowledge (including philosophical knowledge) both quantitatively and qualitatively [from 8 and 9].
    11. Therefore, scientific knowledge is better than non-scientific forms of knowledge (including philosophical knowledge) [from 7 and 10].

A first controversial philosophical premise at play in Mizrahi’s Argument is a premise Mizrahi uses to defend premise 8 of Mizrahi’s Argument. The premise states that we should think about both knowledge and philosophy operationally. As I point out in 2017, Mizrahi needs to premise such accounts of knowledge and philosophy, since otherwise “it won’t be possible for him to measure the quantity of knowledge in scientific and non-scientific disciplines, something Mizrahi needs to do in order to make his argument for 8” (2017, 44).

Mizrahi has three criticisms of my comment here. First, Mizrahi claims to have provided sufficient justification for operationalizing the nature of philosophy and (philosophical) knowledge by noting the controversy surrounding the nature of philosophy. In light of such controversy, citing Lauer, Mizrahi says: “Arguably, as far as answering the question ‘What makes X philosophical?’ goes, [operationalizing philosophy as what professional philosophers do] may be the best we can do (Lauer 1989, 16)” (Mizrahi 2017a, 356; Mizrahi 2017b, 12). So, contrary to what I say (or imply), Mizrahi does not simply assume we should operationalize the nature of philosophy or knowledge. Second, Mizrahi thinks it problematic for me to challenge his premise reducing philosophy to what professional philosophers do without offering my own account of the nature of philosophy (2017b, 13). Third, Mizrahi thinks it strange that a philosopher (presumably, like me) who wants to defend the usefulness of philosophy should criticize his pragmatic account of the nature of philosophy.

As to Mizrahi’s first point, he offers justification for operationalizing the nature of philosophy and knowledge only in the sense of “here’s a reason why I am proceeding in the way that I am.” Indeed, as I point out in 2017, unless he operationalizes the nature of philosophy and knowledge, “it won’t be possible for him to measure the quantity of knowledge in scientific and non-scientific disciplines, something Mizrahi needs to do in order to make his argument for 8” (2017, 44).

Of course, Mizrahi is free to stipulate an understanding of philosophy or knowledge that can be measured empirically (it’s a free country). But insofar as one bemoans the current state of the research university as one obsessed with outcomes, and measuring outcomes empirically, Mizrahi will forgive those who think stipulating an understanding of the nature of philosophy and knowledge as operational is not only shallow insofar as philosophy and knowledge can’t fit into the narrow parameters of another empirical study, but furthermore, begs the question against those who think that, as great as experimental science and its methods are, experimental science does not constitute the only disciplined approach to searching for knowledge and understanding.

Mizrahi even goes so far to say (his way of) operationalizing the nature of knowledge and philosophy is the least controversial way of doing so (2017b, 13). It’s hard to understand why he thinks that is the case. Just citing the fact that philosophers disagree with one another about the nature of philosophy, citing one author who thinks this is the best we can do, and then adding an additional account of what philosophy is to the already large list of different accounts of what philosophy is—for after all, to say philosophy is what philosophers do, is itself to do some philosophy, i.e., metaphilosophy—does not warrant thinking (a way of) operationalizing of philosophy and knowledge is the least controversial way of thinking about philosophy and knowledge.

In addition, many philosophers think it is false that philosophy and philosophical knowledge are reducible to what professional philosophers do (it may be good to recall that Socrates, Plato, Augustine, Descartes, Locke, and Hume were not professional philosophers). Also, some philosophers think that not all professional philosophers are true philosophers (again, for precedent, see the arguments in Plato’s Phaedo and Republic). Still other philosophers will insist on a definition of knowledge such as, knowledge is warranted true belief, and also think much of what is argued in philosophy journals—and perhaps science journals too—does not meet the threshold of being warranted, and so of knowledge.

Perhaps Mizrahi means (his way of) operationalizing philosophy and knowledge are the least controversial ways of thinking about philosophy and knowledge among those engaged in “the scientism debate in philosophy” (2017b, 13). That may be so. In my original response—and in this response too—I’m trying to suggest that there are people interested in evaluating scientism that do not share the scientistic account of philosophy and knowledge of those engaged in “the scientism debate in philosophy.”

Having said something above why I did not describe the nature of philosophy in my 2017, I turn to Mizrahi’s puzzlement at my raising the possibility that we should not operationalize the nature of philosophy and knowledge, given my interest in showing that philosophy is useful. After all, if it may be the case that a published journal article in philosophy does not constitute philosophy or an item of philosophical knowledge, what hope can there be to for responding to those academics who think philosophy is dead or useless?

Mizrahi apparently puts me in the class of folk who want to defend philosophy as useful. Mizrahi also seems to assume the only way to show philosophy is useful is by defining philosophy operationally (2017b, 13). Therefore, it doesn’t make sense for me to be skeptical about operationalizing the nature of philosophy and knowledge.

Is philosophy useful? That depends upon what we mean by ‘useful.’ Philosophy won’t help us cure cancer or develop the next form of modern technology (not directly, at any rate).[5] So it is not useful as physics, chemistry, biology, or mathematics are useful. It is presumably in that technological sense of ‘useful’ that Martin Heidegger says, “It is entirely proper and perfectly as it should be: philosophy is of no use” (Einfuhrung in die Metaphysik; qtd. in Pieper 1992, 41).

But by ‘useful,’ we may mean, “able to help a person live a better life.” In my view, philosophy can be very useful in that sense. A philosopher can help persons live a better life—sometimes even herself—by writing journal articles (that is, there certainly are some excellent philosophy journal articles, and some—often far too few—read and profit from these). But more often than not, since most people who may profit from exposure to philosophy or a philosopher don’t read academic journals (and wouldn’t profit much from doing so, if they did), people’s lives are improved in the relevant sense by philosophy or philosophers insofar as they encounter a good philosopher in the classroom and in every day conversations or by reading classical philosophical works from the ancient, medieval, modern, and contemporary periods.

By operationalizing the nature of philosophy and knowledge, Mizrahi’s Argument fails to account for those occasions, times, and places where most persons exposed to philosophy can—and sometimes do—profit from the experience by gaining knowledge they did not possess before about what makes for a flourishing human life.

A Third Controversial Philosophical Premise in Mizrahi’s Argument

In my 2017 article, I mention a third controversial philosophical premise at play in Mizrahi’s Argument: the view that the knowledge of each academic discipline—in terms of both its output and impact—can be quantitatively measured. Mizrahi objects that I do not “tell us what makes this alleged ‘assumption’ philosophical” (2017b, 13). He also states that I do not provide evidence that it is controversial. Finally, Mizrahi claims:

that we can measure the research output of academic fields is not “contentious” [Brown 2017, 45] at all. This so-called “assumption” is accepted by many researchers across disciplines, including philosophy [see, e.g., Kreuzman 2001 and Morrow & Sula 2011], and it has led to fruitful work in library and information science, bibliometrics, scientometrics, data science [Andres 2009], and philosophy [see, e.g., Wray & Bornmann 2015 and Ashton & Mizrahi 2017] (Mizrahi 2017b, 13).

As for my claim that the premise one can quantify over knowledge produced in academic disciplines is a philosophical premise, I assumed in my 2017 essay that Mizrahi and I were working from common ground here, since Mizrahi states, “it might be objected that the inductive generalizations outlined above [in defense of premise 8 of Mizrahi’s Argument] are not scientific arguments that produce scientific knowledge because they ultimately rest on philosophical assumptions. One philosophical assumption that they ultimately rest on, for example, is the assumption that academic knowledge produced by academic disciplines can be measured” (2017a, 356; emphasis mine).

I supposed Mizrahi to agree with the highlighted portion of the citation above, but it may be that Mizrahi was simply writing in the voice of an objector to his own view (of course, even then, we often agree with some of the premises in an objector’s argument). I also (wrongly) took it to be obvious that the premise in question is a philosophical premise. What else would it be? A piece of common sense? A statement confirmed by experimental science?[6] Something divinely revealed from heaven?

Mizrahi also claims I don’t provide evidence that the claim that we can quantify over how much knowledge is produced in the academy is controversial. What sort of evidence is Mizrahi looking for? That some philosophical paper says so? Surely Mizrahi does not think we can settle a scholarly—let alone a philosophical—dispute by simply making an appeal to an authority. Does Mizrahi think we need sociological evidence to settle our dispute? Is that the best way to provide evidence for a claim? If the answer to either of these last two questions is ‘yes’, then Mizrahi’s Argument for Weak Scientism is begging the question at issue.

But, in any case, I do offer philosophical evidence that the philosophical claim that academic knowledge can be quantitatively measured is controversial in my 2017 article:

in order to measure the amount of scientific and non-scientific, academic knowledge—as Mizrahi needs to do in order to make his argument for premise 8 [of Mizrahi’s Argument]—he needs to define knowledge teleologically—as the goal or aim of an academic discipline—or operationally—as what academics produce. But thinking about the nature of (academic) knowledge in that pragmatic way is philosophically controversial. Therefore, thinking we can measure quantitatively the amount of knowledge across academic disciplines is itself philosophically controversial, since the latter assumption only makes sense on a pragmatic account of knowledge, which is itself a controversial philosophical assumption (2017, 45).

As I noted above, by ‘controversial’ here, I mean there is (at least) a large minority of philosophers, whether we simply count professional philosophers alive today, or also include dead philosophers, who (would) reject the claims that we can collectively quantify over what counts as knowledge, knowledge is teleological, only academics produce philosophical knowledge, and philosophical knowledge is what philosophers publish in academic journals.

Finally, note that Mizrahi’s evidence that (a) reducing what academics know to what can be quantitatively measured is not controversial is that (b) there are academics from across the disciplines, including philosophy, who accept the premise that we can quantify over knowledge produced by academics and (c) the premise that we can quantify over knowledge produced by academic disciplines has led to fruitful work in a number of disciplines, including information science.

But (a)’s itself being controversial (i.e., that a large minority reject it), even false, is consistent with the truth of both (b) and (c). By analogy, it is no doubt also true that (d) academics from across the disciplines, even some philosophers, think quantitative assessment of college teaching is a good idea and (e) much data has been collected from quantitative assessments of college teaching which will be very useful for those seeking doctorates in education. But surely Mizrahi knows that (d) is controversial among academics, even if (e) is true. Mizrahi’s argument that (a) is true on the basis of (b) and (c) is a non-sequitur.

A Fourth Controversial Philosophical Premise

In my 2017 article, I claim that a fourth controversial philosophical premise is doing important work for Mizrahi’s Argument. This premise states: the quantity of knowledge of each academic discipline—in terms of both output and impact—can be accurately measured by looking at the publications of participants within that discipline. I argue that reducing the production of academic knowledge to what academics publish shows a decided bias in favor of the philosophy of education dominating the contemporary research university, in contrast to the traditional liberal arts model that places a high value on reading and teaching classic texts in philosophy, mathematics, history (including the history of science), and literature. Showing such favor is significant for two reasons.

First, it is question-begging insofar as the philosophy of education in modern research universities, prizing as it does the sort of knowledge that the methods of the experimental sciences are specially designed to produce, i.e., new knowledge and discoveries, is itself rooted in a kind of cultural scientism, one that is supported by big business, university administrators, many journalists, most politicians, and, of course, the research scientists and academics complicit in this scientistic way of thinking about the university.[7] Second, since academics produce knowledge in ways other than publishing, e.g., by way of reading, teaching, mentoring, giving lectures, and engaging others in conversation, the premise that the quantity of knowledge of each academic discipline can be accurately measured by output and impact of publications does not “present us with a representative sample of knowledge produced within all academic disciplines” (Brown 2017, 46). That means that Mizrahi’s inference to the conclusion scientists produce more knowledge that non-scientific academics from the premise, scientists produce more publications than non-scientific academics and scientists produce publications that are cited more often that those published by non-scientist academics is logically invalid.

Mizrahi responds to my comments in this context by stating that I am confusing “passing on knowledge” or “sharing knowledge” with “producing knowledge” (2017b, 14). This distinction is significant, thinks Mizrahi, since “as far as the scientism debate is concerned, and the charge that philosophy is useless, the question is whether the methodologies of the sciences are superior to those of other fields in terms of producing knowledge, not in terms of sharing knowledge” (2017b, 14). Finally, Mizrahi also notes that those in the humanities do not corner the market on activities such as teaching, for scientists pass on knowledge by way of teaching too.

Mizrahi seems to assume that sharing knowledge is not a form of producing knowledge. But I would have thought that, if a person S does not know p at time t and S comes to know p at t+1, then that counts as an instance of the production of knowledge, even if some person other than S knows p at t or some time before t or S comes to know p by way of being taught by a person who already knows p. But say, if only for the sake of argument, that Mizrahi is correct to think sharing knowledge does not entail the producing of knowledge. The fact that either Mizrahi does not count passing on or sharing knowledge as a kind of producing of knowledge or Mizrahi’s Argument does not measure the sharing or passing on of knowledge would seem to mean that Mizrahi’s Argument simply measures the production of new knowledge or discoveries, where new knowledge or a discovery can be defined as follows:

(N) New knowledge or discovery =df some human persons come to know p at time t, where no human person or persons knew p before t.

Mizrahi’s focus on knowledge as new knowledge or discovery in Mizrahi’s Argument reinforces a real limitation of (that argument for) Weak Scientism insofar as it equates knowledge with new knowledge. But it also confirms what I said in my 2017 article: Mizrahi’s Argument is question-begging since it has as a premise that knowledge is to be understood as equivalent to the sort of knowledge which the methods of the experimental sciences are specially designed to produce, i.e., new knowledge and discoveries.

Surely philosophers sometimes make new discoveries, or collectively (believe they) make progress, but philosophy (in the view of some philosophers) is more about individual intellectual progress rather than collective intellectual progress (of course, we may think it is also has the power to bring about social progress, but some of us have our real doubts about that). As Josef Pieper says:

‘Progress’ in the philosophical realm is assuredly a problematic category—insofar as it means an ever growing collective accumulation of knowledge, growing in the same measure as time passes. There exists, under this aspect, an analogy to poetry. Has Goethe ‘progressed’ farther than Homer?—one cannot ask such a question. Philosophical progress undeniably occurs, yet not so much in the succession of generations as rather in the personal and dynamic existence of the philosopher himself (1992, 92).

To the charge that scientists teach students too, I, of course, concur. But if passing on knowledge by way of teaching, mentoring, giving lectures, and personal conversations count as ways of producing knowledge, then Mizrahi’s defense of premise 8 of Mizrahi’s Argument does not, as I say in my 2017 article, “present us with a representative sample of knowledge produced within all academic disciplines” (2017, 46). And if passing on knowledge by way of teaching or reading does not count as a way of producing knowledge, then, given what many of us take to be the real intellectual significance of passing on knowledge through teaching and reading, the position Mizrahi is actually defending in 2017a and 2017b is even weaker:

(Very, Very, Very, Very Weak Scientism): When it comes to the knowledge that is produced by academic journals, i.e., the N knowledge or discoveries published in academic journals, knowledge that comes from scientific academic journals is the best.

A Fifth Controversial Philosophical Premise

Although Mizrahi says nothing about it in his 2017b response to my 2017 essay, I think it is important to emphasize again that, in arguing that scientific knowledge is better than non-scientific knowledge in terms of quantity of knowledge, Mizrahi makes use of a fifth controversial philosophical premise in Mizrahi’s Argument: the quantity of knowledge—in terms of output and impact—of each academic discipline can be successfully measured by looking simply at the journal articles published (output) and cited (impact) within that discipline. For to count only journal articles when quantifying over impact of the knowledge of a discipline is, again, to adopt a scientific, discovery-oriented, approach to thinking about the nature of knowledge.

For how often do the works of Plato, Aristotle, Virgil, St. Augustine, St. Thomas Aquinas, Dante, Shakespeare, Descartes, Hume, Kant, Hegel, Marx, and Dostoevsky, just for starters, continue to have research impact on the work of historians, social scientists, theologians, and literature professors, not to mention, philosophers? So Mizrahi’s Argument either begs the question against non-scientist academics for another reason—it neglects to count citations of great thinkers from the past—or, by focusing only on the citation of journal articles, we are given yet another reason to think the sample Mizrahi uses to make his inductive generalization in defense of premise 8 of Mizrahi’s Argument is simply not a representative one.

The Sixth and Ninth Controversial Philosophical Premises

Here I address the following controversial philosophical premises, both of which function as key background assumptions in Mizrahi’s Argument:

(K1) For any two pieces of knowledge, p and q, where p and q are produced by an academic discipline or disciplines, p is to be treated as qualitatively equal to q where measuring the quantity of knowledge produced within academic disciplines is concerned.

(K2) For any two pieces of knowledge, p and q, where p and q are produced by an academic discipline or disciplines, p is to be treated as qualitatively equal to q in the sense of the nobility or importance or perfection of p and q where measuring the quality of p and q, where quality in this latter sense measures the extent to which the theories employed in an academic discipline or discipline productive ofand q enjoy some degree of explanatory, instrumental, and predictive success.

Premise 8 of Mizrahi’s Argument says that scientific knowledge is quantitatively better than non-scientific academic knowledge because scientists publish more journal articles than non-scientists and the journal articles published by scientists are cited more often—and so have a greater “research impact”—than do the journal articles published by non-scientists (2017a, 355-58). In my 2017 essay I note that, in concluding to premise 8 on the basis of his inductive generalizations, Mizrahi is assuming (something such as) K1.

Furthermore, we may reasonably think K1 is false since the production of some sorts of non-scientific knowledge work may be harder than the production of scientific knowledge (and if a piece of work W is harder to publish than a piece of work W1, then, all other things being equal, W is qualitatively better than W1). For example, I mentioned the recent essay by philosopher David Papineau: “Is Philosophy Simply Harder than Science?” (2017). I also offered up as a reason for questioning whether K1 is correct Aristotle’s famous epistemological-axiological thesis that a little knowledge about the noblest things is more desirable than a lot of knowledge about less noble things.[8]

Premise 9 of Mizrahi’s Argument says that scientific knowledge is qualitatively better than non-scientific academic knowledge insofar as scientific theories are more successful than non-scientific theories (including philosophical theories) where the success of a theory is understood in terms of its explanatory, instrumental, and predictive success. In my 2017 response, I suggest that Mizrahi has (something such as) K2 implicitly premised as a background philosophical assumption in his argument for premise 9, and a premise such as K2 is a philosophically controversial one. At the very least, Mizrahi’s implicitly premising K2 in Mizrahi’s Argument therefore limits the audience for which Mizrahi’s Argument will be at all rhetorically convincing. For as I stated in my 2017 response:

Assume . . .  the following Aristotelian epistemological axiom: less certain knowledge (or less explanatorily successful knowledge or less instrumentally successful knowledge or less testable knowledge) about a nobler subject, e.g., God or human persons, is, all other things being equal, more valuable than more certain knowledge (or more explanatorily successful knowledge or more instrumentally successful knowledge or more testable knowledge) about a less noble subject, e.g., stars or starfish. . . . [And] consider, then, a piece of philosophical knowledge P and a piece of scientific knowledge S, where P constitutes knowledge of a nobler subject than S. If S enjoys greater explanatory power and more instrumental success and greater testability when compared to P, it won’t follow that S is qualitatively better than P (2017, 50).

Mizrahi raises a number of objections to the sections of my 2017 essay where I mention implicit premises at work in Mizrahi’s Argument such as K1 and K2. First, I don’t explain why, following Papineau, philosophy may be harder than science (2017b, 9). Second, he offers some reasons to think Papineau is wrong: “producing scientific knowledge typically takes more time, effort, money, people, and resources . . . [therefore], scientific knowledge is harder to produce than non-scientific knowledge” (2017b, 9). Third, he notes I don’t argue for Aristotle’s epistemological-axiological thesis, let alone explain what it means for one item of knowledge to be nobler than another.

Fourth, in response to my notion that philosophy and science use different methodologies insofar as the methods of the former do not invite consensus whereas the methods of the latter do, Mizrahi notes that “many philosophers would probably disagree with that, for they see the lack of consensus, and thus progress in philosophy as a serious problem” (2017b, 10). Fifth, Mizrahi thinks there is precedent for his employing a premise such as K1 in his defense of premise 8 in Mizrahi’s Argument insofar as analytic epistemologists often use variables in talking about the nature of knowledge, e.g., propositions such as ‘if person S knows p, then p is true,’ and therefore treat all instances of knowledge as qualitatively equal (2017b, 13, n. 2).

In mentioning Papineau’s article in my 2017 essay, I offer an alternative interpretation of the data that Mizrahi employs in order to defend premise 8 of Mizrahi’s Argument, an interpretation that he should—and does not—rule out in his 2017a paper, namely, that scientists produce more knowledge than non-scientists not because scientific knowledge is better than non-scientific knowledge but rather because non-scientific knowledge (such as philosophical knowledge) is harder to produce than scientific knowledge. Indeed, Mizrahi himself feels the need to rule out this possibility in his 2017b reply to my 2017 article’s raising this very point (see 2017b, 9).

Mizrahi’s inference about the greater difficulty of scientific work compared to non-scientific academic work such as philosophy goes through only if we think about the production of philosophical knowledge in the operational manner in which Mizrahi does. According to that model of philosophical knowledge, philosophical knowledge is produced whenever someone publishes a journal article. But, traditionally, philosophical knowledge is not that easy to come by. Granted, scientific knowledge too is hard to produce. As Mizrahi well notes, it takes lots of “time, effort, money, people, and resources” to produce scientific knowledge.

But we live in a time that holds science in high regard (some think, too high a regard), not just because of the success of science to produce new knowledge, but because science constantly provides us with obvious material benefits and new forms of technology and entertainment.[9] So it stands to reason that more time, effort, money, and resources are poured into scientific endeavors and more young people are attracted to careers in science than in other academic disciplines. When one adds to all of this that scientists within their fields enjoy a great consensus regarding their methods and aims, which invites greater cooperation among researchers with those fields, it is not surprising that scientists produce more knowledge than those in non-scientific academic disciplines.

But all of that is compatible with philosophy being harder than science. For, as we’ve seen, there is very little collective consensus among philosophers about the nature of philosophy and its appropriate methods. Indeed, many academics—indeed, even some philosophers—think knowledge about philosophical topics is not possible at all. It’s not beyond the pale to suggest that skepticism about the possibility of philosophical knowledge is partly a result of the modern trend towards a scientistic account of knowledge. In addition, some philosophers think philosophical knowledge is harder to acquire than scientific knowledge, if only because of the nature of those topics and questions that are properly philosophical (see Papineau 2017 and Van Inwagen 2015, 14-15).

As for the meaning of Aristotle’s epistemological-axiological claim, I take it that Aristotle thinks p is a nobler piece of knowledge than q if, all others being equal, the object of p is nobler than the object of q. For example, say we think (with Aristotle) that it is better to be a rational being than a non-rational being. It would follow that rational animals (such as human persons) are nobler than non-rational animals. Therefore, applying Aristotle’s epistemological-axiological claim, all other things being equal, knowing something about human persons—particularly qua embodied rational being—is a nobler piece of knowledge than knowing something about any non-rational object.

Now, as Mizrahi points out, not all philosophers agree with Aristotle. But my original point in mentioning Aristotle’s epistemological-axiological thesis was to highlight an implicit controversial philosophical premise in the background of Mizrahi’s Argument. The Aristotelian epistemological-axiological thesis is perhaps rejected by many, but not all, contemporary philosophers. The implicit assumption that Aristotle is wrong that (knowledge of) some object is nobler than (knowledge of) another object is a philosophical assumption (just as any arguments that Aristotle is wrong will be philosophical arguments). Indeed, it may be that any reason a philosopher will give for rejecting Aristotle’s epistemological-axiological thesis will also show that they are already committed to some form of scientistic position.

I say the practice of philosophy doesn’t invite consensus, whereas one of the advantages of an experimental method is that it does. That is a clear difference between philosophy and the experimental sciences, and since at least the time of Kant, given the advantage of a community of scholars being able to agree on most (of course, not all) first principles where some intellectual endeavor is concerned, some philosophers have suggested philosophy does not compare favorably with the experimental sciences.

So it is no surprise that, as Mizrahi notes, “many [contemporary] philosophers . . . see the lack of consensus, and thus progress in philosophy as a serious problem” (2017b, 10). But it doesn’t follow from that sociological fact, as Mizrahi seems to suggest it does (2017, 10), that those same philosophers disagree that philosophical methods don’t invite consensus. A philosopher could lament the fact that the methods of philosophy don’t invite consensus (in contrast to the methods of the experimental sciences) but agree that that is the sober truth about the nature of philosophy (some professional philosophers don’t like philosophy or have science envy; I’ve met a few). In addition, the fact that some philosophers disagree with the view that philosophical methods do not invite consensus shouldn’t be surprising. Philosophical questions are by nature controversial.[10]

Finally, Mizrahi defends his premising (something such as) K1 by citing the precedent of epistemologists who often treat all items of knowledge as qualitatively the same, for example,  when they make claims such as, ‘if S knows p, then p is true.’ But the two cases are not, in fact, parallel. For, unlike the epistemologist thinking about the nature of knowledge, Mizrahi is arguing about and comparing the value of various items of knowledge. For Mizrahi to assume KI in an argument that tries to show scientific knowledge is better than non-scientific knowledge is to beg a question against those who reasonably think philosophy is harder than science or the things that philosophers qua philosophers know are nobler than the things that scientists qua scientists know, whereas epistemologists arguably are not begging a question when engaged in the practice of abstracting from various circumstances (by employing variables) in order to determine what all instances of knowledge have in common.

The Seventh and Eighth Controversial Philosophical Premises

In his attempt to defend the thesis that scientific knowledge is qualitatively better than non-scientific knowledge, Mizrahi assumes that a theory A is qualitatively better than a theory B if A is more successful than B (2017a, 358). He thus thinks about a theory’s qualitative value in pragmatic terms. But not all philosophers think about the qualitative goodness of a theory in pragmatic terms, particularly in a philosophical context, if only because, of two theories A and B, A could be true and B false, where B is more successful than A, and a philosopher may prize truth over successful outcomes.[11] This constitutes a seventh controversial philosophical premise in Mizrahi’s Argument.

In addition, as I point out in my 2017 response, there is an eighth controversial philosophical premise in the background of Mizrahi’s Argument, namely, that a theory A is more successful than a theory B if A is more explanatorily successful than B, and more instrumentally successful than B, and more predictively successful than B. Even if we grant, for the sake of argument, that this is a helpful account of a good scientific explanation, interestingly, Mizrahi thinks these criteria for a successful scientific theory can be rightfully applied as the measure of success for a theory, simpliciter.

I argued in my 2017 response that to think philosophical theories have to be, for example, instrumentally successful (in the way experimental scientific theories are, namely, (a) are such that they can be put to work to solve immediate material problems such as the best way to treat a disease or (b) are such that they directly lead to technological innovations) and predicatively successful in an argument for the conclusion that scientific knowledge is better than non-scientific knowledge is “to beg the question against non-scientific ways of knowing, ways of knowing that do not, by their very nature, employ controlled experiments and empirical tests as an aspect of their methodologies” (2017, 48).

In responding to my comments, Mizrahi makes three points. First, I criticize his account of explanation without offering my own account of explanation (2017b, 19). Second, passing over my comments that good philosophical theories need not be instrumentally successful (in the relevant sense) or predicatively successful, Mizrahi argues that I can’t say, as I do, that good philosophical theories explain things but do not enjoy the good-making qualities of all good explanations. As Mizrahi states, “the good-making properties of [good] explanations include unification, coherence, simplicity, and testability. Contrary to what Brown (2017, 48) seems to think, these good-making properties apply to explanations in general, not just to scientific explanations in particular” (2017b, 19) and

Contrary to what Brown asserts without argument, then, ‘To think that a theory T is successful only if—or to the extent that—it enjoys predicative success or testability’ is not to beg the question against non-scientific ways of knowing. For, insofar as non-scientific ways of knowing employ IBE [i.e., inference to the best explanation], which Brown admits is the case as far as philosophy is concerned, then their explanations must be testable (as well as unified, coherent, and simple) if they are to be good explanations (Mizrahi 2017b, 2); emphases in the original).

Mizrahi offers as evidence for the claim that all good explanations are testable and enjoy predicative power the ubiquity of such a claim in introductory textbooks on logic and critical thinking, and he offers as a representative example a chapter from a textbook by two philosophers, Sinnott-Armstrong & Fogelin 2010.

I plead guilty to not offering an account of good explanation in my 2017 article (for the same sort of reason I gave above for not defining philosophy). What I contend is that just as philosophical methods are different in kind from those of the experimental scientists, so too is a good philosophical explanation different in kind from what counts as a good explanation in an empirical science. That is not to say that philosophical and scientific explanations have nothing significant in common, just as it is not to say that the practice of philosophy has nothing in common with experimental scientific practice, despite their radical differences.

For both philosophy—at least on many accounts of its nature—and experimental science are human disciplines: their premises, conclusions, theories, and proposed explanations must submit to the bar of what human reason alone can establish.[12] Indeed, many philosophers who do not share Mizrahi’s scientistic cast of mind could happily agree that good philosophical explanations are coherent and, all other things being equal, that one philosophical explanation E is better than another E1 if E is more unified or simpler or has more explanatory power or depth or modesty than E1.

Others would add (controversially, of course) that, all other things being equal, philosophical theory E is better than E1 if E makes better sense of, or is more consistent with, common-sense assumptions about reality and human life,[13] e.g., if theory E implies human persons are never morally responsible for their actions whereas E1 does not, then, all other things being equal, E1 is a better philosophical theory than theory E. In addition, we may think, taking another cue from Aristotle, that a philosophical theory E is better than a theory E1, all other things being equal, if E raises fewer philosophical puzzles than E1.

Mizrahi also premises that good philosophical explanations have to be testable (2017a, 360; 2017b, 19-20). But what does he mean? Consider the following possibilities:

(T1) A theory or explanation T is testable if and only if T can be evaluated by controlled experiments and other methods characteristic of the experimental sciences, e.g., inductive generalization.

(T2) A theory or explanation is testable if and only if T can be evaluated by (a) controlled experiments and other methods characteristic of the experimental sciences, e.g., inductive generalization or (b) on the basis of deductive arguments or (c) the method of disambiguating premises, or (d) the method of refutation by counter-example or (e) inference to the best explanation or (e) thought experiments (or (f) any number of other philosophical methods or (g) methods we use in everyday life).

In my 2017 response, I took Mizrahi to mean (something such as) T1 by ‘a good explanation is testable’. For example, Mizrahi states: “as a general rule of thumb, choose the explanation that yields independently testable predictions” (2017a, 360; emphases mine). If Mizrahi accepts T1 and thinks all good explanations must be testable, then, as I stated in my 2017 response, “philosophical theories will . . . not compare favorably with scientific ones” (2017, 49).

But as philosopher Ed Feser well points out, to compare the epistemic values of science and philosophy and fault philosophy for not being good at making testable predications is like comparing metal detectors and gardening tools and concluding gardening tools are not as good as metal detectors because gardening tools do not allow us to successfully detect for metal (2014, 23).

In other words, if T1 is what Mizrahi means by ‘testable’ and Mizrahi thinks all good explanations are testable, then Mizrahi’s Argument does, as I contend in my 2017 response, “beg the question against non-scientific ways of knowing, ways of knowing that do not, by their very nature, employ controlled experiments and empirical tests as an aspect of their methodologies” (2017, 48; see also Robinson 2015).

But perhaps Mizrahi means by ‘an explanation’s being testable’ something such as T2. But in that case, good philosophical work, whether classical or contemporary, will compare favorably with the good work done by experimental scientists (of course, whether one thinks this last statement is true will depend upon one’s philosophical perspective).

Some Concluding General Remarks About Mizrahi’s Argument

Given the number of (implied) controversial philosophical premises that function as background assumptions in Mizrahi’s Argument, that argument should not convince those who do not already hold to (a view close to) Weak Scientism. As we’ve seen, Mizrahi premises, for example, that philosophy should be operationally defined as what philosophers do, that knowledge within all academic disciplines should be operationally defined as what academics publish in academic journals, K1, K2, and all good explanations are explanatorily, instrumentally, and predicatively successful.

Of course, the number of controversial philosophical premises at play in Mizrahi’s Argument isn’t in and of itself a philosophical problem for Mizrahi’s Argument, since the same could be said for just about any philosophical argument. But one gets the distinct impression that Mizrahi thinks Mizrahi’s Argument should have very wide appeal among philosophers. If Mizrahi wants to convince those of us who don’t already share his views, he needs to do some more work defending the implied premises of Mizrahi’s Argument, or else come up with a different argument for Weak Scientism.

Indeed, many of the implied controversial philosophical premises I’ve identified in Mizrahi’s Argument are, as we’ve seen, not only doing some heavy philosophical lifting in that argument, but such premises imply that (something such as) Weak Scientism is true, e.g., the quantity of knowledge of each academic discipline—in terms of both output and impact—can be accurately measured by looking at the publications of participants within that discipline, K1, K2, a theory A is more successful than a theory B if A is more explanatorily successful than B, and more instrumentally successful than B, and more predictively successful than B, and an explanation is a good explanation only if it is testable in the sense of T1. Mizrahi’s Argument thus begs too many questions to count as a good argument for Weak Scientism.

Mizrahi is also at pains to maintain that his argument for Weak Scientism is a scientific and not a philosophical argument, and this because a significant part of his argument for Weak Scientism not only draws on scientific evidence, but employs “the structure of inductive generalization from samples, which are inferences commonly made by practicing scientists” (2017a, 356). I admit that a scientific argument from information science is “a central feature of Mizrahi’s Argument” (Brown 2017, 50) insofar as he uses scientific evidence from information science to support premise 8 of Mizrahi’s Argument. But, as I also note in my 2017 essay, “Mizrahi can’t reasonably maintain his argument is thereby a scientific one, given the number of controversial philosophical assumptions employed as background assumptions in his argument” (2017, 51).

My objection that Mizrahi’s Argument is a piece of philosophy and not a scientific argument is one that Mizrahi highlights in his response (2017b, 9). He raises two objections to my claim that Mizrahi’s Argument is a philosophical and not a scientific argument. First, he thinks I have no grounds for claiming Mizrahi’s Argument is a philosophical argument since I don’t give an account of philosophy, and I reject his operationalized account of philosophy (2017b, 15). Second, Mizrahi states that

Brown seems to think than an argument is scientific only if an audience of peers finds the premises of that argument uncontroversial. . . . Accordingly, Brown’s (2017) criterion of controversy [according to Mizrahi, I think this is dubitability] and his necessary condition for an argument being scientific have the absurd consequence that arguments presented by scientists at scientific conferences (or published in scientific journals and books) are not scientific arguments unless they are met with unquestioned acceptance by peer audiences (2017b, 16).

I have already addressed Mizrahi’s comment about the nature of philosophy above. In response to his second objection, Mizrahi wrongly equates my expression, “controversial background philosophical assumptions,” with his expression, “controversial premises in a scientific argument.” Recognizing this false equivalency is important for evaluating my original objection, and this for a number of reasons.

First, what Mizrahi calls the “premises of a scientist’s argument” (2017b, 15) are, typically, I take it, not philosophical premises or assumptions. For is Mizrahi claiming that scientists, at the presentation of a scientific paper, are asking questions about propositions such as K1 or K2?

Second, Mizrahi and I both admit that philosophical background assumptions are sometimes in play in a scientific argument. Some of these claims, e.g., that there exists an external world, some philosophers will reject. What I claimed in my 2017 essay is that a scientific argument—in contrast to a philosophical argument—employs background philosophical assumptions that “are largely non-controversial for the community to which those arguments are addressed, namely, the community of practicing scientists” (2017, 15). For example, an argument that presupposed the truth of theism (or atheism), would not be, properly speaking, a scientific argument, but, at best, a philosophical argument that draws on some scientific evidence to defend certain of its premises.

So, contrary to what Mizrahi says, my argument that Mizrahi’s Argument is not a scientific argument neither implies that Darwin’s Origin of the Species is not science, nor does it imply a scientist’s paper is not science if audience members challenge that paper’s premises, methods, findings, or conclusion. Rather, my comment stands unscathed: because of the number of philosophical background premises that are controversial among the members of the audience to which Mizrahi’s Argument is directed—presumably all academics—Mizrahi’s Argument is not a scientific argument but rather, a philosophical argument that draws on some data from information science to defend one of its crucial premises, namely premise 8.

But, as I pointed out above, even Mizrahi’s argument for premise 8 in Mizrahi’s Argument is a philosophical argument, drawing as that argument does on the controversial philosophical background premises such as philosophy should be operationally defined as what philosophers do, knowledge within all academic disciplines should be operationally defined as what academics publish in academic journals, and K1.

Finally, there is another reason why Mizrahi himself, given his own philosophical principles, should think Mizrahi’s Argument is a piece of philosophy. As we’ve seen, Mizrahi thinks that philosophy and philosophical knowledge should be defined operationally, i.e., philosophy is what philosophers do, e.g., publish articles in philosophy journals, and philosophical knowledge is what philosophers produce, i.e., publications in philosophy journals (see Mizrahi 2017a, 353). But Mizrahi’s 2017a paper is published in a philosophy journal. Therefore, by Mizrahi’s own way of understanding philosophy and science, Mizrahi’s Argument is not a scientific argument, but a philosophical argument (contrary to what Mizrahi says in both 2017a and 2017b).

[4] Here follows a description of something like one traditional way of thinking about the intellectual discipline of philosophy, one that I often give in my introduction to philosophy classes. It describes philosophy by comparing and contrasting it with the experimental sciences, on the one hand, and revealed theology, on the other hand: philosophy is that intellectual discipline which investigates the nature of ultimate reality, knowledge, and value (i.e., subjects the investigation of which raise questions that can’t be settled simply by running controlled experiments and taking quantitative measurements) by way of methods such as deductive argumentation, conceptual analysis, and reflection upon one’s own experiences and the experiences of others (where the experiences of others include, but are not limited to, the experiences of experimental scientists doing experimental science and the experiences of those who practice other intellectual disciplines), by way of the natural light of human reason alone (where this last clause is concerned, philosophy is usefully compared and contrasted with revealed theology: revealed theology and philosophy investigate many of the same questions, e.g., are there any sorts of actions that ought to never be performed, no matter what?, but whereas philosophy draws upon the natural light of human reason alone to answer its characteristic questions [in this way philosophy is like the experimental sciences], and not on any supposed divine revelations, revealed theology makes use of the natural light of reason and [what revealed theologians believe by faith is] some divine revelation).

[5] Although, as I pointed out in my 2017 essay, it seems one can plausibly argue that modern science has the history of Western philosophy as a necessary or de facto cause of its existence, and so the instrumental successes of modern science also belong to Western philosophy indirectly.

[6] For academics don’t agree on which claims count as knowledge claims, e.g., some will say we can know propositions such as murder is always wrong, others don’t think we can know ethical claims are true. Are we, then, to simply measure those claims published at the university that all—or the great majority of academics believe count as knowledge claims? But in that case, we are no longer measuring what counts as knowledge, but rather what a certain group of people, at a certain time, believes counts as knowledge. I don’t think I’m going out on a limb when I say cataloguing what a certain group of people believe is sociology and not philosophy.

[7] See, e.g., Alasdair MacIntyre 2009, esp. 15-18 and 173-180.

[8] See, e.g., On the Parts of Animals, Book I, chapter 5 [644b32-645a1]. See also St. Thomas Aquinas, Summa contra gentiles, book one, ch. 5, 5 and Summa theologiae Ia. q. 1, a. 5, ad1.

[9] Of course, modern science and technology produce negative effects too, e.g., pollution, and, according to some, increased dissolution of traditional social bonds. But, because the positive effects of modern science and technology are often immediate and the negative effects often arise only after some time has passed, it is hard for us to take into account, let alone see, the negative consequences of modern science and technology. For some helpful discussion of the history of the culturally transformative effects of modern science and technology, both positive and negative, see Postman 1993.

[10] See, e.g., Bourget & Chalmers 2014. As that study shows, when a good number of contemporary philosophers were polled about a number of major philosophical questions, every question asked turns out to be collectively controversial. Although the paper certainly identifies certain tendencies among contemporary philosophers, e.g., 72.8% identified as atheists, and only 14.6% identified as theists, that latter number is still a healthy minority view so that its seems right to say that whether atheism or theism is true is collectively controversial for contemporary philosophers. For some good discussion of philosophical questions as, by nature, controversial, see also Van Inwagen 2015, 11-19.

[11] A small point: in responding to my comment here, Mizrahi misrepresents what I say. He renders what I call in my 2017 article “the seventh assumption” as “One theory can be said to be qualitatively better than another” (2017b, 12). That’s not what I say; rather I suggest Mizrahi’s Argument premises a theory A is qualitatively better than theory B if A is more successful than theory B.

[12] In this way, philosophy and the experimental sciences differ from one historically important way of understanding the discipline of revealed theology. For example, as St. Thomas Aquinas understands the discipline of revealed theology (see, e.g., Summa theologiae Ia. q. 1.), revealed theology is that scientia that treats especially of propositions it is reasonable to believe are divinely revealed, propositions that can’t be known by the natural light of human reason alone. In addition, the wise teacher of revealed theology can (a) show it is reasonable to believe by faith that these propositions are divinely revealed and (b) use the human disciplines, especially philosophy, to show how propositions that are reasonably believed by faith are not meaningless and do not contradict propositions we know to be true by way of the human disciplines, e.g., philosophy and the sciences.

In 2017a,[1] Moti Mizrahi distinguishes a position he calls Weak Scientism—of all the knowledge we have, scientific knowledge is the best—from what he calls Strong Scientism—the only real kind of knowledge is scientific knowledge. Whereas Strong Scientism may have serious problems, Mizrahi argues Weak Scientism is a defensible position. In my 2017 response, I raise some objections to the arguments Mizrahi employs to defend Weak Scientism. Mizrahi replies to my objections in 2017b. This essay has two parts. In the first part, I briefly summarize both Mizrahi’s arguments in defense of Weak Scientism in 2017a and the problems for Mizrahi’s arguments I identify in my 2017 essay. In the second part, I offer replies to Mizrahi’s objections in 2017b.

Mizrahi’s Arguments for Weak Scientism and Some Objections to those Arguments

In 2017a, Mizrahi does at least three things. First, he distinguishes persuasive and non-persuasive definitions of scientism and argues for adopting the latter rather than the former. Second, Mizrahi distinguishes Strong Scientism from the position he defends, Weak Scientism. Third, Mizrahi defends Weak Scientism in two ways. The first way Mizrahi defends Weak Scientism is by attempting to defeat the following two objections to that position:

(O1) It is epistemically impossible to offer scientific evidence for Weak Scientism.

(O2) It is viciously circular to support Weak Scientism with scientific evidence.

Where Mizrahi’s attempt to defeat O1 is concerned, he offers what he takes to be a scientific argument for Weak Scientism. Here follows a schema of the argument:

7. One kind of knowledge is better than another quantitatively or qualitatively.[2]
8. Scientific knowledge is quantitatively better than non-scientific knowledge (including philosophical knowledge) in terms of the number of journal articles published and the number of journal articles cited.
9. Scientific knowledge is qualitatively better than non-scientific knowledge (including philosophical knowledge) insofar as scientific theories are more successful than non-scientific theories (including philosophical theories) where the success of a theory is understood in terms of its explanatory, instrumental, and predictive success.
10. Therefore, scientific knowledge is better than non-scientific forms of knowledge (including philosophical knowledge) both quantitatively and qualitatively [from 8 and 9].
11. Therefore, scientific knowledge is better than non-scientific forms of knowledge (including philosophical knowledge) [from 7 and 10].

For the sake of ease of reference, let us call the argument above, Mizrahi’s Argument. A second way Mizrahi defends Weak Scientism in his 2017a paper is directly by way of Mizrahi’s Argument. For if Mizrahi’s Argument is sound, it not only shows O1 is false, but it shows Weak Scientism is true.

In my 2017 essay, I raise a number of objections to what Mizrahi argues in 2017a. First, I argue Weak Scientism is not really a form of scientism. Second, I argue Mizrahi does not give an advocate of Strong Scientism good reasons to adopt Weak Scientism. Third, I contend that, contrary to what Mizrahi supposes (2017a, 354), Weak Scientism is not relevant by itself for mediating the debate between defenders of philosophy and those who think philosophy is useless. Fourth, I argue that Mizrahi’s Argument presupposes philosophical positions that many academics reject, so that Mizrahi’s Argument is not as powerful as he seems to think. Fifth, I argue that some of the background philosophical premises in Mizrahi’s Argument are question-begging.

Sixth, I contend that Mizrahi’s primary argument for Weak Scientism—Mizrahi’s Argument—is a philosophical argument and not a scientific argument, and so he does not defeat objection O1. Seventh, I argue that Mizrahi does not defeat objection O2, since there is a way to think about the defensibility of deductive inference that does not involve making inferences. Finally, I offer two counter examples to Mizrahi’s contention that the use of a persuasive definition of a term necessarily involves both begging the question against those who reject such a definition and a failure to provide reasons for thinking that definition is true.

Responding to Mizrahi’s Objections

I now respond to objections Mizrahi raises in 2017b to my 2017 essay. In each section of this part I highlight an objection I raised for Mizrahi 2017a in my 2017 response, I explain Mizrahi’s response to that objection in 2017b, and I offer a response to Mizrahi’s response. In many cases Mizrahi has misconstrued one of my objections, and so I here clarify those objections. In other cases, Mizrahi misses the point of one of my objections, and so I try to make those objections clearer. Still in other cases, Mizrahi makes some good points about objections I raise in 2017, although not points fatal to those objections, and so I revise my objections accordingly. Finally, in some cases Mizrahi asks for more information and so I give it, at least where such information is relevant for evaluating Mizrahi’s defenses of Weak Scientism.

Is Weak Scientism Really Scientism?  

In 2017, I argue that Weak Scientism is not really strong enough to count as scientism. For, given Weak Scientism, philosophical knowledge may be nearly as valuable as scientific knowledge. In fact, given that Weak Scientism claims only that scientific knowledge is better than non-scientific academic knowledge (see, e.g., Mizrahi 2017a, 354; 356), Weak Scientism is compatible with the claim that non-academic personal knowledge, moral knowledge, and religious knowledge are all better than scientific knowledge. Certainly, Mizrahi’s defenses of Weak Scientism in 2017a and 2017b don’t show that scientific knowledge is better than non-academic forms of knowledge acquisition. Traditional advocates of scientism, therefore, will not endorse Weak Scientism, given their philosophical presuppositions.

Mizrahi raises two objections to my arguments here. First, even if I’m right that one could think about philosophical knowledge as nearly as valuable as scientific knowledge, this does nothing to show Weak Scientism is not strong enough to count as scientism, since “one of the problems with the scientism debate is precisely the meaning of the term ‘scientism’” (Mizrahi 2017a, 351-353; qtd. in Mizrahi 2017b, 10). Second, Mizrahi notes that scientism is an epistemological thesis and not a psychological one and that he sets out to show what traditional advocates of scientism should accept, and not what they would accept (2017b, 11).

Say Strong Scientism is false, if only because it is self-refuting and subject to good counter-examples. The questions remain, why think Weak Scientism, particularly the weak version of that view Mizrahi ends up defending in 2017a, is really a form of scientism? And why think advocates of Strong Scientism should accept Weak Scientism?

Take the first question. As Mizrahi’s list of citations at the beginning of 2017a makes clear, there already exist very entrenched linguistic conventions with respect to the meaning of ‘scientism.’ As Mizrahi notes, one such meaning is the pejorative or “persuasive” sense of ‘scientism’ that Mizrahi does not like, which (again as Mizrahi himself points out) is quite pervasive, e.g., scientism is an “exaggerated confidence in science (Williams 2015, 6)” (Mizrahi 2017a, 351), and “an exaggerated kind of deference towards science (Haack, 2007, 17; 18)” (Mizrahi 2017a, 351). Mizrahi also mentions persuasive descriptions of scientism in the work of Pigliucci and Sorrell. Why does this diverse group of philosophers use the word ‘scientism’ in this way? Perhaps because it is simply one of the meanings the word ‘scientism’ has come to have in the English language.

Consider, for example, the entry for ‘scientism’ in the Oxford English Dictionary. It has two main headings. Under the first heading of ‘scientism’ is a descriptive use of the term: “A mode of thought which considers things from a scientific viewpoint.” This meaning of ‘scientism’ is not relevant for our purposes since Weak Scientism is a normative and not a descriptive claim. Under the second heading of ‘scientism’ we have:

Chiefly depreciative [emphasis in the original]. The belief that only knowledge obtained from scientific research is valid, and that notions or beliefs deriving from other sources, such as religion, should be discounted; extreme or excessive faith in science or scientists [emphasis mine]. Also: the view that the methodology used in the natural and physical sciences can be applied to other disciplines, such as philosophy and the social sciences (2017).

For better or worse, something such as the following so-called persuasive definition of scientism is thus one of the meanings the word ‘scientism’ has come to have in the English language:

(Scientism1): having an exaggerated confidence in science or the methods of science.

Presumably, some philosophers use ‘scientism’ in the sense of Scientism1 because they think some contemporary thinkers have an exaggerated confidence in science, it is convenient to have a word for that point of view, and, since there is already a term in the English language which picks out that sort of view, namely, ‘scientism’, philosophers such as Williams, Haack, Sorrell, and Pigliucci reasonably use ‘scientism’ in the sense of Scientism1.

But what does this have to do with the question whether Weak Scientism is really a species of scientism? As we’ve seen, one of the meanings commonly attached to ‘scientism’ is the idea of having an exaggerated or improper view of the power or scope of science. But as Mizrahi also notes in 2017a, there is a second sort of meaning often attached to ‘scientism’:

(Scientism2): the view that states the methods of the natural sciences are the only (reliable) methods for producing knowledge or the methods of the natural sciences should be employed in all of the sciences or all areas of human life.

Mizrahi cites Richard Williams (Mizrahi 2017a, 351) and Alex Rosenberg (2017a, 352) as examples of philosophers who use ‘scientism’ with the meaning identified in Scientism2. In addition, as we saw above, this is (part of) the second entry for ‘scientism’ in the Oxford English Dictionary. This is good evidence that Scientism2 picks out one meaning that ‘scientism’ currently has in the English language.

The prevalence of Scientism2 as a meaning of ‘scientism’ goes some distance towards explaining the commonality of the use of Scientism1 as a meaning of ‘scientism’, since many philosophers, historians, psychologists, sociologists, and natural scientists think it is false that science is the only method for (reliably) producing knowledge or the methods of the natural sciences should be employed in all of the sciences or all areas of human life.

Of course, here, as in other areas of life, what some people think is a vice others think a virtue. So philosophers such as Alex Rosenberg think ‘scientism’ in the sense of Scientism2 is true, but reject that acceptance of Scientism2 represents “an exaggerated confidence in science,” since, in their view, the view that science is the only reliable path to knowledge is simply the sober truth.

What I am calling Scientism2 Mizrahi calls Strong Scientism, a view he thinks has problems (see Mizrahi 2017a, 353-354). Furthermore, Mizrahi argues that Weak Scientism is the view that advocates of Strong Scientism should adopt and the view philosophers who want to defend philosophy against charges of uselessness should attack (2017a, 354). But, as I point out in 2017, there is a huge logical gap between Strong Scientism (Scientism2) and Weak Scientism. To see this, recall that Mizrahi defines Weak Scientism as follows:

(Weak Scientism): Of all the knowledge we have, scientific knowledge is the best knowledge (2017a, 354).

In my 2017 response, I suggest that, as we take into account the philosophical premises at play in Mizrahi’s Argument, it turns out Weak Scientism becomes an even weaker thesis. For example, consider a strong interpretation of Weak Scientism:

(Fairly Strong Weak Scientism): Of all the knowledge we have, including non-academic forms of knowledge such as common sense knowledge, personal knowledge, moral knowledge, and religious knowledge, scientific knowledge is the best knowledge.

There is a big logical gap between Strong Scientism (Scientism2) and Fairly Strong Weak Scientism. For Strong Scientism (Scientism2) states that scientific knowledge is the only kind of real knowledge (or the only kind of reliable knowledge). But, for all Fairly Strong Weak Scientism says, scientific knowledge is just barely better, e.g., just barely more reliable, than religious knowledge or philosophical knowledge. There’s a huge logical gap between Strong Scientism (Scientism2) and Fairly Strong Weak Scientism.

As Mizrahi notes (2017a, 354; 356), and to which his practice in 2017a conforms, he is not interested in defending Fairly Strong Weak Scientism. This means that Mizrahi really has something such as the following in mind by Weak Scientism:

(Very Weak Scientism) When it comes to the kinds of knowledge produced within the academy, scientific knowledge is the best.

But there is a big logical gap between Strong Scientism (Scientism2) and Very Weak Scientism.  In fact, as I point out in my 2017 article, given other philosophical presuppositions Mizrahi makes or positions Mizrahi defends in 2017a, the view Mizrahi actually defends in 2017a gets even (and ever) weaker:

(Very, Very Weak Scientism) When it comes to the knowledge that is produced by academic publications, scientific publications are the best.

(Very, Very, Very Weak Scientism): When it comes to the knowledge that is produced by academic journals, knowledge that comes from scientific academic journals is the best.

Now, acceptance of Very, Very, Very Weak Scientism leaves open the possibility that there is philosophical knowledge produced by way of monographs, lectures, and conversations that is better than any sort of scientific knowledge. And, as I point out in my 2017 article, ultimately, something such as Very, Very, Very, Weak Scientism is the view Mizrahi defends in 2017a. Is Very, Very, Very, Weak Scientism really scientism? Given the conventional uses of ‘scientism’ and the huge logical gap between Weak Scientism—even on the strongest reading of the position—and Scientism2, it doesn’t make sense to think of Mizrahi’s Weak Scientism as a species of scientism.

Consider some other reasons for thinking it strange that Weak Scientism counts as a species of scientism. Imagine a person named Alice, about whom, let us say for the sake of argument, the following statements are true: (a) Alice thinks there is a God; (b) she knows the reasons for not thinking there is a God; (c) she has published influential attempted defeaters of the arguments that there is no God; (d) even though she reasonably thinks there are some good, if not compelling, arguments for the existence of God, she thinks it reasonable to believe in God without argumentative evidence; (e) she has published an influential account, by a prestigious academic press, of how a person S can be rational in believing in God, although S does not have good argumentative evidence that God exists; (f) she has published a much discussed argument that belief in God makes better sense of an evolutionary account of the human mind (understood as a reliable constellation of cognitive powers) than does an atheistic evolutionary one, and (g) she thinks that modern science is the greatest new intellectual achievement since the fifteenth century. If believing modern science is the greatest new intellectual achievement since the fifteenth century is (roughly) equivalent to Weak Scientism, then Alice is (roughly) an advocate of Weak Scientism. But it seems odd, to say the least, that Alice—or someone with Alice’s beliefs—should count an advocate (even roughly) of scientism.

One may also reasonably ask Mizrahi why he thinks the position picked put by Weak Scientism is a species of scientism in the first place. One may be inclined to think Weak Scientism is a species of scientism because, like Strong Scientism, Weak Scientism (as formulated by Mizrahi) puts too high a value on scientific knowledge. But Mizrahi won’t define or describe scientism in that way for the reasons he lays out in 2017a.

Given the conventional uses of ‘scientism,’ the huge logical gap between Weak Scientism and Scientism2, and Mizrahi’s refusal to employ a persuasive definition of scientism, it is not clear why Mizrahi’s Weak Scientism should count as a species of scientism. A friendly suggestion: perhaps Mizrahi should simply coin a new word for the position with respect to scientific knowledge and non-scientific forms of academic knowledge he wants to talk about, rather than simply coining a new (and problematic) meaning for ‘scientism.’

Mizrahi’s Argument Does Not Show Why Advocates of Strong Scientism Should Endorse Weak Scientism  

Given Mizrahi’s interest in offering “a defensible definition of scientism” (2017a, 353), which, among other things, means an alternative to Strong Scientism (2017a, 353-354), we can also consider the question, why think advocates of Strong Scientism should adopt Weak Scientism? Mizrahi does not argue in 2017a, for example, that there are (reliable) forms of knowledge other than science. His argument simply presupposes it. But if Mizrahi wants to convince an advocate of Strong Scientism that she should prefer Weak Scientism, Mizrahi can’t presuppose a view the advocate of Strong Scientism believes to be true (particularly, if it’s not even clear that Weak Scientism is a form of scientism).

In addition, as I try to show in my 2017 response, Mizrahi’s Argument relies on other philosophical positions that advocates of Strong Scientism do not accept and Mizrahi does not offer good philosophical arguments for these views. Indeed, more often than not, Mizrahi has simply stipulated a point of view that he needs in order to get Mizrahi’s Argument off the ground, e.g., that we should operationalize what philosophy is or we should operationalize what counts as knowledge in a discipline (for more on these points, see below). If philosophical premises that the advocate of Strong Scientism do not accept are doing the heavy lifting in Mizrahi’s Argument as I claim, premises which are undefended from the perspective of the advocate of Strong Scientism, then it’s not clear why Mizrahi thinks advocates of Strong Scientism should accept Weak Scientism based upon Mizrahi’s Argument.

For even Fairly Strong Weak Scientism is a lot different from the view that advocates of Strong Scientism such as Alex Rosenberg hold. Here’s Rosenberg: “If we’re going to be scientistic, then we have to attain our view of reality from what physics tells us about it. Actually, we’ll have to do more than that: we’ll have to embrace physics as the whole truth about reality” (2011, 20). Indeed, it seems the only reason an advocate of Strong Scientism such as Rosenberg would be even tempted to consider adopting Weak Scientism is because it contains the word ‘scientism.’

But once the advocate of Strong Scientism sees that an advocate of Weak Scientism admits the possibility that there is real knowledge other than what is produced by the natural sciences—indeed, in Mizrahi 2017a and 2017b, Weak Scientism is compatible with the view that common sense knowledge, knowledge of persons, and religious knowledge are each better than scientific knowledge—the advocate of Strong Scientism, at least given their philosophical presuppositions, will reject Weak Scientism out of hand. Given also that Mizrahi has not offered arguments that there is real knowledge other than scientific knowledge, and given that Mizrahi has not offered arguments for a number of views required for Mizrahi’s defense of Weak Scientism (see below), views that advocates of Strong Scientism reject, Mizrahi also does not show why advocates of Strong Scientism should adopt Weak Scientism.

How Is Weak Scientism by Itself Relevant Where the Philosophy-Is-Useless-Objection Is Concerned?

Mizrahi seems to think Weak Scientism is relevant for assessing the philosophy-is-useless claim. He states: “I propose . . . Weak Scientism is the definition of scientism those philosophers who seek to defend philosophy against accusations of uselessness . . . should attack if they want to do philosophy a real service” (2017, 354). But why think a thing like that?

In his response to my 2017 essay, Mizrahi gets his reader off on the wrong foot by reinterpreting my question as “Does Weak Scientism entail that philosophy is useless?” (2017b, 9; 11). Mizrahi says that I “object to [Mizrahi’s] argument in defense of Weak Scientism by complaining that Weak Scientism does not entail philosophy is useless” (2017b, 11) and he goes on to point out that he did not intend to defend the view that philosophy is useless.

But this is to miss the point of the problem (or question) I raise for Mizrahi’s paper in this section, which is, “how is Weak Scientism by itself relevant where the philosophy-is-useless-objection is concerned?” (Brown 2017, 42). For Weak Scientism itself implies nothing about the degree to which philosophical knowledge is valuable or useful other than stating scientific knowledge is better than philosophical knowledge.

Given Mizrahi’s definition of Weak Scientism, (a) one could accept Weak Scientism and think philosophy is extremely useful (there is no contradiction in thinking philosophy is extremely useful but scientific knowledge is better than, for example, more useful than, philosophical knowledge); (b) one could accept Weak Scientism and think philosophy is not at all useful (one may be thinking philosophical knowledge is real but pretty useless and that scientific knowledge is better than philosophical knowledge); (c) one could obviously reject Weak Scientism and think philosophy very useful (depending upon what one means by ‘philosophy is useful’; more on this point below), and (d) one could reject Weak Scientism and think philosophy useless (as some advocates of Strong Scientism surely do).

Accepting (or rejecting) Weak Scientism is compatible both with thinking philosophy is very useful and with thinking philosophy is useless. So it’s hard to see why Mizrahi thinks “Weak Scientism is the definition of scientism those philosophers who seek to defend philosophy against accusations of uselessness . . . should attack if they want to do philosophy a real service” (2107a, 354).
