Chris Tweedt proposes that there is no independent concept of contrastive knowledge. He allows that we can meaningfully and in fact helpfully say that a person knows that p rather than q. But this is shorthand for something that can be said in a more traditional way as that the person knows that if p or q then p. I have two worries about this line. First, I do not know how to understand the conditional here. And second, I suspect that the suggested interpretation takes away the motive for using a contrastive idiom in the first place.

What Kind of Conditional?

So, could “Sophia knows that it is a goldfinch rather than a canary” mean “Sophia knows that if it is a goldfinch or a canary then it is a goldfinch”? What could “if” mean for this to be plausible? The simplest possibility is that it is a material conditional. But this cannot be right.

Sophia, who knows very little about small birds, sees an eagle land on a nearby high branch. From its size and distinctive shape she can tell immediately that it is a large raptor and not a little seed-eater such as a goldfinch or canary. That means she will know that “(Goldfinch v Canary) É Goldfinch” is true, because she knows that the antecedent is false. For the same reason she will know that “(Goldfinch v Canary) É Canary” is true. But surely she knows neither that it is a goldfinch rather than a canary nor that it is a  canary rather than a goldfinch, and more than surely not both.

Perhaps then it is a subjunctive (counterfactual) conditional: if it had been a goldfinch or a canary then it would have been a canary. I suppose there conceivably are circumstances where a high-tech procedure could transform a bird embryo into one of a different species. It might be that the most possible such procedure can transform bird embryos into canaries but never into goldfinches. Suppose this is so.

Now suppose that Sophia’s cousin Sonia is an expert ornithologist and knows at a glance what species the blue tit a metre away is. But she also knows about the embryo-transforming procedure so she knows that if it had been a goldfinch or a canary then it would have been a canary. So she knows that it is a goldfinch rather than a canary? Of course not.

The remaining possibility is that it is an indicative conditional. For many philosophers these are just material conditionals, so that won’t do. But for others they are a distinct kind. One way of paraphrasing the resulting interpretation is as “if it turns out to be a goldfinch or a canary, it will turn out to be a goldfinch”. This is still not suitable. Suppose Sonia knows immediately that it is a blue tit but is dealing with an ignorant person who doubts her judgement. She admits that there are other things it could on closer examination — which in fact is not necessary — turn out to be.

And then goldfinch would be more likely to result than canary. So she accepts this particular indicative conditional (if goldfinch or canary then goldfinch.). But she too does not know that it is a goldfinch rather than a canary, because she knows it is a blue tit. (For the differences between kinds of conditionals see Jonathan Bennett A Philosophical a Guide to Conditionals. Oxford: Clarendon Press, 2003.)

Understanding the Contrastive Idiom

These may be problems about formulating the claim rather than about the underlying intention. However I do not think that any version of the idea that all uses of “knows that p rather than q” can be represented as choosing the least wrong from a list of alternatives will work. For one use of the contrastive idiom is to describe limitations in a person’s ability to distinguish possibilities.

Consider four people with varying degrees of red/green colour blindness but with otherwise normal human colour-distinguishing capacities. (Sorry, it has to be four. For the distinctions see https://en.wikipedia.org/wiki/Color_blindness.)

Alyosha has normal r/g vision;

Boris partial capacity (say 70% of normal);

Yekaterina limited capacity (say 40% of normal);

Zenaida no r/g discrimination at all.

They are each presented with one of those familiar colour charts, one in which the most salient figure 3 in vivid green is completed to 8 in dull orange against a background of orangy murkiness. Alyosha knows that it is a 3, so that it is 3 rather than 7 and that it is 3 rather than 8. As a result he knows both that if it is 3 or 8 it is 3 and that if it is 3 or 7 it is 3. Boris can see that it is either 3 or 8; he is not sure which but thinks it is 3.

So he knows that it is 3-or-8 rather than 7 but not that it is 3 rather than a 7 (since for all he knows it might be 8 rather than 3). He also knows that if it is 3-or-8 or 7 then it is 7, and that if it is 3 or 7 then it is 3 (since the antecedent of the conditional rules out 8). Yekaterina thinks that it is 3 or 8, but she has no idea which. She knows that if it is 3 or 7 then it is 3, and that if it is 8 or 7 then it is 8, but nothing more from these possibilities.

Finally Zenaida. She hasn’t a clue about anything needing r/g discrimination and has none of this knowledge. I am assuming that all factors except for r/g discrimination are favourable to knowledge for all four people.

All of these descriptions are natural applications of the “knows rather than” construction in English. They show a fine-grained transition from full contrast to none and in particular that the “if p or q then p” versions appear and disappear at different stages in the transition than the “p rather than q” versions do. That is the point of the contrastive construction, to allow us to make these distinctions.

Contrastivism (see, e.g., Schaffer 2004) is the view that knowledge is not a binary relation between a subject and a proposition but a ternary relation between a subject S, a proposition p (the proposition attributed as known and thus entailed by the knowledge attribution; we can call it the “target proposition”) and an incompatible (cf. Rourke 2013, sec.2) and false contrast proposition q (a “contrast”).[1]

The form of a knowledge attribution is thus not S knows that p but S knows that p rather than q. According to contrastivism, it’s elliptical, at least, to say that Chris knows that that bird is a goldfinch. Rather, we should say something like the following: Chris knows that that bird is a goldfinch rather than a raven. Chris might not know that that bird is a goldfinch rather than a canary. There can, of course be more than one contrasting proposition; in this case we can consider the disjunction of all the contrasting propositions to constitute the contrast proposition.

A Problem and Tweedt’s Proposed Solution

Chris Tweedt’s thought-provoking “Solving the Problem of Nearly Convergent Knowledge” discusses one kind of argument against the binary view and in favor of contrastivism. The argument (see Schaffer 2007) is based on the claim that knowing that p consists in knowing the answer to a question of the form Is p rather than q the case? (“Is this bird a goldfinch rather than a raven?”; “Is it a goldfinch rather than a canary?”). Put differently, knowing that p consists in knowing the correct answer to a multiple choice question (“What bird is this? A: A goldfinch; B: A raven”; What bird is this? A: A goldfinch; B: A canary”).

The binary account faces a problem because it has to claim that if one knows the answer to one such question (“Is it a goldfinch rather than a raven?”) then one also knows the answer to the other question (“Is it a goldfinch rather than a canary?”). However, one might only be able to answer one question but not the other. This is the problem of convergent knowledge. This, argues Schaffer, speaks in favor of contrastivism.

Some defenders of the binary view (see Jespersen 2008; Kallestrup 2009) have proposed the following way out: One does not know the same proposition when one knows the answers to different contrastive (multiple choice) questions which share a “target” (a target proposition). Rather, the corresponding knowledge has the form S knows that (p and not q). Our subject might know that that bird is a goldfinch and not a raven while it might not know that it is a goldfinch and not a canary.

Schaffer (2009) has a response to this: Even though there is no convergence of knowledge here there is “near convergence” which is still bad enough. Using the principle of closure of knowledge under known entailment[2] one can easily acquire knowledge of the second proposition on the basis of knowledge of the first. If Chris knows that that bird is a goldfinch and not a raven, then Chris also knows or can easily come to know, according to the binary view, that that bird is a goldfinch.

Since Chris also knows that whatever is a goldfinch is not a canary, he also knows or can easily come to know that that bird is not a canary. So, he knows or can easily come to know that that bird is a goldfinch and not a canary. Given that this is implausible, the problem of convergent knowledge is reincarnated as the problem of “nearly convergent knowledge”.

Tweedt’s ingenuous reply in favor of the binary account (see also van Woudenberg 2008) proposes to analyze the known answer to a contrastive (multiple choice) question as having conditional form:

(0) If p or q, then p.[3]

Question: Is that bird a goldfinch rather than a raven? Answer: If it is a goldfinch or a raven, then it is a goldfinch!

Tweedt claims that this solves the problem of convergent knowledge because the answer to the question “Is that bird a goldfinch rather than a raven?”, namely

(1) If that bird is a goldfinch or a raven, then it’s a goldfinch,

is not “a few quick closure steps away” (see Tweedt 2018, 220) from the answer to the question “Is that bird a goldfinch rather than a canary?”, namely

(2) If that bird is a goldfinch or a canary, then it’s a goldfinch.

A Problem with Tweedt’s Proposal

Tweedt does not add an explicit argument to his claim that (2) isn’t just a few easy closure steps away from (1). Here is an argument that (2) is indeed just a few easy closure steps away from (1). If that’s correct, then Tweedt’s proposal fails to solve the problem of nearly convergent knowledge.

Let “g”, “r” and “c” stand in for “That bird is a goldfinch”, “That bird is a raven”, and “That bird is a canary” respectively. We can then, following Tweedt, assume (about some subject S) that

(3) S knows that if g or r, then g.

The proposition g is the target proposition here, not r (in the latter case our subject would know that if g or r, then r, instead). Since targets and contrasts are mutually incompatible, we may also assume that

(4a) S knows that if g, then not r;

(4b) S knows that if g, then not c.

Finally, we may assume that

(5) S knows that g or r.

To be sure, one can ask contrastive questions where both propositions are false: Is Einstein rather than Fido the dog the inventor of the telephone? One might want to answer that Einstein rather than Fido invented the telephone (whether one also believes falsely or doesn’t believe that Einstein invented the telephone).

However, this is a deviant case not relevant here because we are interested in cases where one of the contrasting propositions is true and particularly in knowledge that p (where p is the target). If that knowledge is construed in a binary way, then it involves knowledge of one of the contrasting propositions (p) that it is true; if it is construed as knowledge that p rather than q, then it still obeys the factivity principle for knowledge and thus entails that p. So, we can assume here that

g or r

is true.[4] We may also assume that in standard cases the subject can know this. Hence:

(5) S knows that g or r.[5]

A closure principle like (Closure) together with (3) and (5) entails

(6) S knows that g.[6]

(Closure) together with (4b) and (6) entails

(7) S knows that not c.

So, there are only a few quick and easy “closure steps” to the implausible (7).[7] And we can add that disjunction introduction will allow the subject to come to know (on the basis of (6)) that g or c

(8) S knows that g or c.

(We could also argue for (8) along the lines of the argument above for (5)). Conjunction introduction together with (6) and (8) will allow the subject to know that (g or c) and g:

(9) S knows that (g or c) and g.

Since whenever a conjunction is true, a corresponding conditional is true, the subject can also come to know that

If g or c, then g.

In other words:

(10) S knows that if g or c, then g.[8]

There are then also quick and easy closure steps leading from Tweedt’s (1) to (2). So, the problem of nearly convergent knowledge remains unsolved.

Defending Tweedt?

There is more than one strategy for Tweedt to defend his proposal of a solution to the problem of nearly convergent knowledge. One would be to modify the closure principle in such a way that certain steps are not allowed any more. For instance, one could try to argue (4b) and (6) don’t lead to (7) because a valid closure principle doesn’t allow knowledge-producing inferences from easy-to-know propositions to hard-to-know propositions.

This kind of idea is well-known from discussions about skepticism: I might know that I have hands, and I might also know that if I have hands, then I am not merely hallucinating that I have hands, but I don’t know that I am not merely hallucinating that I have hands. Fred Dretske and Robert Nozick as well as some others have argued for such a view (see Dretske 2005 and Nozick 1981, ch.3). However, I am not sure whether Tweedt wants to choose this strategy. And it doesn’t seem easy to find a modification of the closure principle that is not ad hoc and has independent reasons in its favor.

Another strategy would be to identify other analyses of the answer to a contrastive (multiple choice) question. Perhaps one can improve on Tweedt’s response in a way similar to the one in which he attempts to improve on Kallestrup’s (and Jespersen’s) response to the original problem of convergent knowledge. I have to leave open here whether there is an analysis that does the trick, and what it could be (see, e.g., Steglich-Petersen 2015).

Could one take Tweedt’s conditional (0) not as a material conditional but rather as a subjunctive conditional? I am afraid that this would constitute a change of topic. Knowledge is factive and what would be the case (P) if something else (Q) were the case does not tell us anything about whether P or Q is the case, even if the corresponding subjunctive conditional is indeed true.

It might be more promising to explore the potential of a complaint about question begging: Isn’t Schaffer’s diagnosis that one can know (1) without knowing (2) already presupposing the truth of contrastivism? Why should one believe that there is a problem with knowing (2) but not with knowing (1) if not because one has already accepted contrastivism about knowledge?

One final side remark on an alleged advantage of binary accounts like Tweedt’s. He argues (see Tweedt 2018, 223) that contrastivism doesn’t take the skeptical problem seriously (enough) and rather deflates it; one might even want to say that contrastivism changes the topic. According to contrastivism I can know the Moorean proposition that I have hands rather than stumps even if I do not know the anti-skeptical proposition that I have hands rather than am merely hallucinating hands. Closure does not support any claim that if I know the one, then I know the other, too. Tweedt thinks this is a disadvantage of contrastivism. However, contrastivists like Schaffer would see this as an advantage. It seems to me that both ways of looking at the anti-skeptical potential of contrastivism have something going for them. In this context, it might be better to leave the question open whether skepticism can be deflated or not. (Similar points will apply to Tweedt’s remarks concerning the debate about expert disagreement; see Tweedt 2018, 223)

Conclusion

Ingenuous as Tweedt’s proposal is, it does not, I think, solve the problem of nearly convergent knowledge. However, this does not mean that a ternary account of knowledge has to be preferred to a binary account. I think that there are serious problems for contrastivism that make the binary account the better options. But this is something for another occasion.

[1] We can allow for a different kind of contrastive knowledge relation where the contrast can also be true. Suppose I know of Jo, the president of the cheese club and also my dentist, that Jo is my dentist. Since I have no clue who might be the president of the cheese club, it could be appropriate to express all this by saying that I know that Jo is my dentist rather than the president of the cheese club. However, against this speaks that the latter is best understood as saying that I know that Jo is my dentist rather than that I know that Jo is the president of the cheese club. But even if there was such an alternative kind of contrastivity of knowledge, we can leave it aside here.

[2] Here is a basic version: (Closure) If S knows that p, and if S knows that p entails q, then S knows that q. Whistles and bells should be added but nothing depends on these here; we can use (Closure) or other simple variants of it here.

[3] Tweedt adds that not all knowledge or all answers to questions are conditional in form (see Tweedt 2018, 222).

[4] See also Tweedt 2018, 224, fn.11 and 225, fn.14. Given (4a) and therefore also given that if g, then not r, we can also rule out that both propositions are true. Could r be true and g be false? Sure, but then r would be the target proposition, not g. This would not constitute a different case.

[5] Even if one insists that knowledge of the answer to a contrastive question is compatible with the lack of truth of any of the contrasting propositions, one still has to accept that there are other cases where there is a true target. And for such cases one still needs a convincing solution of the problem of nearly convergent knowledge.

[6] A different route to (6) uses (5) and (8) below together with the claim that all contrasting propositions are mutually incompatible. However, one might have doubts about the latter assumption and allow for propositions in the contrast set to be mutually compatible (as long as they are incompatible with the target proposition). I want to leave this issue open here and will thus not put weight on this alternative route to (6). – Here is still another route to (6). If it is true (following (3)) that if g or r, then g, (thus ruling out the case in which g is false and r is true) and if it is also true (following (4a)) that if g, then not r (thus ruling out the case in which both g and r are true), and if, finally, r is the disjunction of all the propositions contrasting with g (thus ruling out the case in which both g and r are false), then we are left with only one case: the case in which g is true and r is false. Since this is a case where g is true, S can come to know g on the basis of the considerations just given. However, in many cases the contrast set does not contain all propositions except the target proposition. In all these cases, we need to use another route to (6).

[7] If one replaces c by some proposition about the obtaining of a skeptical scenario (like An evil demon makes me hallucinate goldfinches), then one gets to even more drastic cases and implications.

[8] Again, if one replaces c by some proposition about the obtaining of a skeptical scenario (like An evil demon makes me hallucinate goldfinches), then one gets to even more drastic conclusions like the following one: S knows that if he is looking at a goldfinch or is suffering from a demon-induced hallucination of a goldfinch, then he is looking at a goldfinch. Hence, given the above, S can also come to know he is looking at a goldfinch and not suffering from a demon-induced hallucination of a goldfinch.

I would like to thank the editors of the Social Epistemology Review and Reply Collective for giving me the opportunity to review Mark McBride’s rich and rewarding book. To begin, I will give a—fairly high-level—overview of its contents. I will then raise some concerns and make some (mildly) critical comments.

Overview

The book is split into two parts. Part 1 concerns the issue of basic knowledge (and justification), whereas the second concerns (putative necessary) conditions on knowledge (specifically, conclusive reasons, sensitivity and safety conditions). We can start with Part 1. As McBride defines it, basic knowledge is “knowledge (or justification) which is immediate, in the sense that one’s justification for the known proposition doesn’t rest on any justification for believing other propositions” (p. 1).

Two central issues in Part 1 are (i) what, exactly, is wrong with Moore’s “proof” of the external world (Chapter 1) (ii) what, exactly, is wrong with inferences that yield “easy knowledge” (Chapters 2-3). Take these arguments, which for ease of reference I’ll call MOORE and EASY-K respectively:

MOORE:

(Visual appearance as of having hands).
1-M. I have hands.
2-M. If I have hands, an external world exists.
3-M. An external world exists.

EASY-K:

(Visual appearance as of a red table).
1-EK. The table is red.
2-EK. If the table is red, then it is not white with red lights shining on it.
3-EK. The table is not white with red lights shining on it.

It seems like a visual appearance as of having hands can give one knowledge of 1-M, and 2-M seems to be knowable a priori. But it seems wrong to hold that one can thereby come to know 3-M. (And mutatis mutandis for EASY-K and 3-EK).

I want to single out three of McBride’s claims about MOORE and EASY-K. First, it is commonly taken that “dogmatist” responses to MOORE (such as Pryor 2000) are at a disadvantage with respect to “conservative” responses (such as Wright 2004). The dogmatist holds that having a visual appearance as of hands provides immediate warrant for 1-M, whereas the conservative holds that one can have warrant for 1-M only if one has a prior entitlement to accept 3-M. Thus the dogmatist seems forced to accept that warrant can “transmit” from the premises of MOORE to the conclusion, whereas the conservative can deny that warrant transmission occurs.

In Chapter 1 McBride turns this on its head. First, he argues that, while a conservative such as Crispin Wright can maintain that the premises of MOORE don’t transmit “non-evidential” warrant to the conclusion, he must allow that “evidential” warrant does transmit from the premises to the conclusion. Second, he argues that Wright cannot avail himself of what McBride (following Davies 2004) takes to be a promising diagnosis of the real problem with MOORE. According to Martin Davies, MOORE is inadequate because it is of no use in the epistemic project of settling the question whether the external world exists. But, for Wright, there can be no such project, because the proposition that the external world exists is the “cornerstone” on which all epistemic projects are built.

Second, in Chapter 3 McBride seeks to show that the dogmatist can supplement Davies’ account of the problem with Moore’s proof in order to diagnose the problem with EASY-K. According to McBride, EASY-K is problematic not just in that it is of no use in settling the question whether the table is not white with red lights shining on it, but also in that there are all sorts of ways in which one could settle this question (e.g. by investigating the lighting sources surrounding the table thoroughly).

Thus, EASY-K is problematic in a way that MOORE isn’t: while one could avail oneself of a better argument for the conclusion of EASY-K, it is harder to see what sort of argument could improve on MOORE.

Third, while Part 1 is generally sympathetic to the dogmatist position, Chapter 5 argues that the dogmatist faces a more serious problem. The reader interested in the details of the argument should consult Chapter 5. Here, I just try to explain the gist. Say you endorse a closure principle on knowledge like this:

CLOSURE: Necessarily, if S knows p, competently deduces q from p, and thereby comes to believe q, while retaining knowledge of p throughout, then S knows q (p. 159).

It follows that, if one comes to know 1-EK (the table is red) by having an appearance as of a red table, then competently deduces 3-EK (the table is not white with red lights shining on it) from 1-EK while retaining knowledge of 1-EK, then one knows 3-EK. But—counter-intuitively—having an appearance as of a red table can lower the credence one ought to have in 3-EK (see pp. 119-20 for the reason why).

It therefore seems inarguable that, if you are in a position to know 3-EK after having the appearance, you must have been in a position to know the 3-EK prior to the appearance. So it seems like the conservative position must be right after all. In order for your appearance as of a red table to furnish knowledge that there is a red table you must have been in a position to know that the table was not white with red lights shining on it prior to having the appearance as of a red table.

The second part of McBride’s book concerns putative (necessary) conditions on knowledge, in particular conclusive reasons (Chapter 6), sensitivity (Chapter 7) and safety (Chapter 8). McBride dedicates a chapter to each condition; the book finishes with a (brief) application of safety to legal knowledge (Chapter 9). While most epistemologists tend to argue that either sensitivity or (exclusive) safety are a (necessary) condition on knowledge, McBride provides a (qualified) defense of both.

In the case of sensitivity, this is in part because, if sensitivity were a condition on knowledge, then—as Nozick (1981) famously held—CLOSURE would be false, and so the argument against dogmatism (about knowledge) in Chapter 5 would be disarmed. Because of the centrality of sensitivity to the argument in Part 1, and because the chapters on conclusive reasons and sensitivity revolve around similar issues, I focus on sensitivity in what follows.

Here is an initial statement of sensitivity:

SENSITIVITY: S knows p only if S sensitively believes p, where S sensitively believes p just in case, were p false, S would not believe p (p. 160).

Chapter 7 (on sensitivity) is largely concerned with rebutting an objection from John Hawthorne (2004) to the effect that the sensitivity theorist must also reject these two principles:

EQUIVALENCE: If you know a priori that p and q are equivalent and you know p, then you are in a position to know q.

DISTRIBUTION: If one knows p and q, then one is in a position to know p and to know q.

Suppose I have an appearance as of a zebra. So I know:

(1) That is a zebra.

By EQUIVALENCE I can know:

(2) That is a zebra and that is not a cleverly disguised mule.

So by DISTRIBUTION I can know:

(3) That is not a cleverly disguised mule.

But, by SENSITIVITY, while I can know (1), I can’t know (3) because, if I were looking at a cleverly disguised mule, I would still believe I was looking at a zebra. Hawthorne concludes that the sensitivity theorist must deny a range of plausible principles, not just CLOSURE.

McBride’s basic response is that, while SENSITIVITY is problematic as stated, it can be modified in such a way that the sensitivity-theorist can deny EQUIVALENCE but keep DISTRIBUTION. More importantly, this rejection of EQUIVALENCE can be motivated on the grounds that initially motivate SENSITIVITY. Put roughly, the idea is that simple conjunctions like (4) already cause problems for SENSITIVITY:

(4) I have a headache and I have all my limbs.

Imagine you form the belief in (4) purely from your evidence of having a headache (and don’t worry about how this might be possible). While you clearly don’t know (4), your belief does satisfy SENSITIVITY, because, if (4) were false, you wouldn’t still believe it (if you didn’t have a headache, you wouldn’t believe you did, and so you wouldn’t believe (4)).

The underlying problem is that SENSITIVITY tells you to go the nearest possible world in which the relevant belief is false and asks what you believe there, but a conjunctive belief is false so long as one of the conjuncts is false, and it might be that one of the conjuncts is false in a nearby possible world, whereas the other is false in a more distant possible world. So the sensitivity theorist needs to restrict SENSITIVITY to atomic propositions and add a new condition for conjunctive propositions:

SENSITIVITY*: If p is a conjunctive proposition, S knows p only if S believes each of the conjuncts of p sensitively (p. 167).

If we make this modification, the sensitivity theorist now has an independent reason to reject EQUIVALENCE, but is free to accept DISTRIBUTION.

Critical Discussion

While this only touches on the wealth of topics discussed in McBride’s book, I will now move on to the critical discussion. I will start by registering two general issues about the book. I will then develop two criticisms in a little more length, one for each part of the book.

First, while the book makes compelling reading for those already versed in the literatures on transmission failure, easy knowledge and modal conditions on knowledge, the central problematics are rarely motivated at any length. Moreover, while McBride does draw numerous (substantive) connections between the chapters, the book lacks a unifying thesis. All this to say: This is maybe more of a book for the expert than the novice. But the expert will find a wealth of interesting material to chew over.

Second, readers of the Collective might find the individualism of McBride’s approach striking. McBride is almost exclusively concerned with the epistemic statuses of individuals’ beliefs, where those beliefs are formed through simple processes like perception and logical inference. The one part of the book that does gesture in a more social direction (McBride’s discussion of epistemic projects, and the dialectical contexts in which they are carried out) is suggestive, but isn’t developed in much detail.

Turning now to more substantive criticisms, in Part 1 McBride leans heavily on Davies’ solution to the problem with MOORE. I want to make two comments here. First, it is natural to interpret Davies’ solution as an inchoate form of contextualism (DeRose 1995; Lewis 1996): whether MOORE (and EASY-K?) transmits warrant to its conclusion depends on the context in which one runs the inference, in particular, the project in which one is engaged.

This raises a host of questions. For example: does McBride hold that, if we keep the context (project) fixed, no transmission failure occurs? That is: if we’re working with the (easier) project of deciding what to believe, does an instance of MOORE transmit warrant from premises to conclusion? If so, then if we’re working with the (harder) project of settling the question, does an instance of MOORE fail to transmit warrant? (This would fit with the more general contextualist line in response to the skeptical problem, so this is only a request for clarification).

Second, and more importantly, we need to distinguish between the project of fully settling the question whether p and the project of partially settling the question whether p. Let’s grant McBride (and Davies) that someone who runs through an instance of MOORE has not fully settled the question whether there is an external world. But why think that—at least by the dogmatist’s lights—they haven’t partially settled the question? If dogmatism is true, then having the appearance as of a hand provides immediate warrant for believing that one has a hand, and so, via MOORE, for believing that there is an external world.

McBride (like many others) finds this conclusion unpalatable, and he invokes the distinction between the project of deciding what to believe and the project of settling the question in order to avoid it. But this distinction is overly simplistic. We can settle questions for different purposes, and with different degrees of stability (cf. “the matter is settled for all practical purposes”). The dogmatist seems forced to allow that MOORE is perfectly good for settling the question of whether there is an external world for a range of projects, not just one.

(I have a parallel worry about the solution to the problem of easy knowledge. Let’s grant McBride that one problem with EASY-K is that there are far better ways of trying to establish that the table is not white but bathed in red light. But why think that—at least by the dogmatist’s lights—it isn’t a way of trying to establish this? To point out that there are better ways of establishing a conclusion is not yet to show that this particular way is no way at all of establishing the conclusion).

Finally, in his response to Hawthorne’s objection to the sensitivity theorist McBride is at pains to show that his modification of SENSITIVITY isn’t ad hoc. To my mind, he does an excellent job of showing that the sensitivity theorist should reject EQUIVALENCE for reasons entirely independent of Hawthorne’s objection.

This suggests (at least to me) that the problem is not one of ad hocness, but rather that sensitivity theorists are forced to endorse a wide range of what Keith DeRose (1995) calls “abominable conjunctions” (cf. “I know that I have hands, but I don’t know that I’m not a handless brain in a vat”). DeRose’s own response to this problem is to embed something like SENSITIVITY in a contextualist theory of knowledge attributions. DeRose proposes the following “rule”:

Rule of Sensitivity: When it’s asserted that S knows (or doesn’t know) p, then, if necessary, enlarge the sphere of epistemically relevant worlds so that it at includes the closest worlds in which p is false (cf 1995, 37).

His idea is that, when the question of whether S knows p becomes a topic of conversation, we expand the range of worlds in which S’s belief must be sensitive. Imagine I assert “I know that I have hands”. In order for this assertion to be true, it must be the case that, if I didn’t have hands, I wouldn’t believe that I did.

But now imagine I assert “I know that I’m not a handless brain in a vat”. In order for this new assertion to be true, it must be the case that, if I were a handless brain in a vat, I wouldn’t believe that I wasn’t. Plausibly, this will not be the case, so I can’t truly assert “I know that I’m not a handless brain in a vat”. But no abominable conjunction results, because I can no longer truly assert “I know that I have hands” either.

My suggestion is that, if McBride were to adopt DeRose’s contextualist machinery, he would not only have a way of responding to the problem of abominable conjunctions, but also an interesting modification to DeRose’s “rule of sensitivity”.

For note that DeRose’s rule seems subject to the same problem McBride sees with SENSITIVITY: when I assert “I have a headache and I have all my limbs” we only need to expand the range of worlds to include worlds in which I don’t have a headache, and so my assertion will remain true in the updated context created by my assertion. Further, adopting this suggestion would furnish another link between Part 1 and Part 2: solving the problem of basic knowledge and formulating a satisfactory sensitivity condition both require adopting a contextualist theory of knowledge attributions.

Bryan Van Norden’s book rightly castigates the exclusion or minimizing of non-Western philosophy in mainstream US philosophy curricula. I was shocked by the willful ignorance and arrogance of those such as able philosopher of biology, Massimo Pigliucci, whom, before reading the quote about Eastern thought, I highly respected. Van Norden is on target throughout with his criticism of Western professional philosopher’s dismissive provincialism. I only worry that his polemic, though accurately describing the situation, will not at all convert the unconverted. Calling the western philosophers who exclude non-Western philosophy “Trumpian philosophers” is both accurate and funny, but unlikely to make them more sympathetic to multi-cultural philosophy.

A Difficult History

Westerners until the last third of the twentieth century denied that there was any significant traditional Chinese science. Part of this was based on racial prejudice, but part of it was that by the nineteenth century, after the Opium War and the foreign concessions were made, Chinese science had degenerated, and superstitious aspects of such things as geomancy and astrology, rather than the earlier discoveries of geography and astronomy dominated.  Prior to the late 1950s for professional Western historians of science, and, until decades later (or even never) the public, scoffed at the idea of sophisticated traditional Chinese science. Chinese insight into astronomy, biology, and other fields was rejected by most people, including respectable historians of science.

The British biochemical embryologist and Marxist Joseph Needham over the second half of the twentieth century in the volumes of Science and Civilization in China gradually revealed the riches of Chinese knowledge of nature. There, is of course the issue of whether traditional Chinese knowledge of nature, and that of other non-Western peoples, often with the exception of Middle Eastern science, can be should be called science. If science is defined as necessarily including controlled experiments and mathematical laws, then Chinese knowledge of nature cannot be called science. Needham himself accepted this definition of science and made the issue of why China never developed science central to his monumental history.

However, Needham discovered innumerable discoveries of the Chinese of phenomena denied in Western science for centuries. Chinese astronomers recorded phenomena such as new stars (Novae) appearing, stellar evolution (change of color of stars), and sunspots in astronomy, None of these were recorded by ancient and medieval Western astronomers. Famously, modern astronomers have made use of millennium old Chinese recordings of novae to trace past astronomical history.

In China, the compass was known and detailed magnetic declination maps were made centuries before the West even knew of the compass. Geobotanical prospecting, using the correlation of plants with minerals in the soil, the idea that mountains move like waves, and on and on. Since field biology, observational astronomy, and historical geology in modern Western science usually do not involve experiments, and many contemporary philosophers of biology deny that there are biological laws, the “experiment and mathematical laws” definition of science may be too narrow.

An example of the chauvinist rejection of Chinese science, and of Needham’s monumental work is that of a respected Princeton historian, Charles Coulston Gillispie. In his review of the first volumes of Needham he warned readers not to believe the contents because Needham was sympathetic to the Communists. Ironically, in the review, Gillispie tended to dismiss applied science and praised the purely theoretical science supposedly unique to the West, accusing Needham of “abject betrayal of the autonomy of science.”

Also ironically, or even comically, in the margin of Gillispie’s reply, doubling down on the denunciation of Communism and defense of pure, non-materialist science was an advertisement recruiting guided nuclear missile scientists for Lockheed! One hopes, but doubts, that Gillispie was embarrassed by his review, as he made similar comments in his Edge of Objectivity, also suggesting that the Arabs and the Chinese could not be trusted with nuclear weapons as “we” can, with our superior moral values.

The Heights of Chinese Philosophy

Even decades after Needham’s magisterial sequence of volumes had been appearing, Cromer in an anti-multicultural book claims not only that China had no science, but that the Chinese had no interest in or knowledge of the world beyond China (neglecting the vast trade on the Silk Road during the ancient and medieval periods, amazingly varied Chinese imports during the Tang Dynasty, the voyages of exploration of Zheng He, the Three Jeweled Eunuch (perhaps a contradiction in terms), and the most complete map of the world before the 1490s (from Korea, but probably from Chinese knowledge and available in China).

Hopefully there will be a process of recognition of non-Western philosophy by American analytic philosophers of the sort that began fifty years earlier for Chinese knowledge of nature among historians. So far this has hardly happened.

One possibility for the integration of Asian philosophy into mainstream philosophy curricula is the integration of non-Western philosophy into the standard history of philosophy courses. One easy possibility of integration is including non-Western philosophy in the standard Ancient Philosophy and Medieval Philosophy curriculum. While teaching Ancient as well as Chinese philosophy in the last two decades I have (perhaps too often) drawn parallels between and contrasts of Greek and Chinese philosophy. However, very few students take both courses. Until this coming year Eastern philosophy was offered yearly, but not as a required part of the history sequence, and few students were in both courses, I worried whether these in-class comparisons fell mostly on deaf ears.

I have thought about the possibility of courses on ancient, medieval, and early modern philosophy including non-Western philosophy of the period. There are a couple of introductory philosophy anthologies, such as Daniel Bonevac’s, apparently now out of print, that include much non-Western philosophy. (Ironically, Bonevac is literally a “Trumpian philosopher,” in the sense of having supported Donald Trump.) Robert C. Solomon included discussion of some Chinese philosophy in his survey but shows total ignorance of modern research on Daoism, doubting that Laozi was an older contemporary of Confucius but rather at least one or two centuries later. Some ways a course that covered both Greek and Chinese philosophy could make comparisons between the two are suggested below. Of course, the usual, casual, comparison of the two involves an invidious contrast perhaps less strong than that of Pigliucci.

A Genuinely Modest Proposal

My proposal involves not introductory surveys but histories of philosophy from the Presocratics to the German romantics and early twentieth century philosophers.

Parallels between the Warring States philosophers and the Pre-Socratics have been noted by among others Benjamin Schwartz in The World of Thought in Ancient China. The Pre-Socratics’ statements have numerous parallels to those of Chinese philosophers of the same period. Qi has some parallels to the air of Anaximenes, in particular in terms of condensation as the source of objects. The Dao of Laozi, as source of all things, yet being indefinable and ineffable has resemblances to the Apeiron of Anaximander.

Of course, many of the paradoxes (that an arrow does not move, the paradox of metrical extension, that a length can be divided indefinitely, that an assemblage of infinitely small points can add up to a finite length) are almost identical with those of Zeno. Of course, the emphasis on Being in Western philosophy from Parmenides through Aristotle to Aquinas and other medieval contrasts most strongly with the emphasis on non-being in Laozi and its presence with less emphasis in Zhuangzi. West’s Early Greek Philosophy and the Orient has many evocative suggestions of influences of the East on the Presocratics. There is extensive work on the parallels and contrasts of the ethics of Mencius and that of Aristotle. The concept and role of the concept Qi has strong similarities to the Stoic notion of pneuma, as described, for instance in Sambursky’s Physics of the Stoics.

A.C. Graham in Disputers of the Dao argues that as the formal logical approaches of the early Wittgenstein, Russell, and logical positivism in the first half of the twentieth century gave way to the later Wittgenstein, and French deconstruction developed, these parts of Western philosophy more closely approximated to the approaches of traditional Chinese philosophy.

Shigehisa Kuriyama has provocatively and insightfully written on the comparison of traditional Chinese medicine and Greek Hippocratic medicine on the body. There have been many articles speculating on the relation of Greek skepticism being influenced by Eastern thought via Alexander’s invasion of India. Diogenes Laertius’s claims that Pyrrho (of later Pyrrhonian skepticism) went to India with Alexander where was influenced by the gymnosophists (“naked sophists”) he met there. C. Beckwith has argued that Phyrronism is a product of Buddhism. Jay Garfield, though thinking the influence question is a red herring, has written extensively and insightfully on the logical isomorphisms between Greek and Tibetan skeptical theses.

Buddhist logic of contradiction can be compared with and at least partially explicated by some twentieth century logics that incorporate contradictions as not illogical. These include presupposition logic as Buddhist. (Though a former colleague told me three people who worked on this died horrible deaths, one by cancer, another by auto accident, so I should avoid studying this area). Other twentieth century symbolic logic systems that allow contradictions as not fatal are Nicholas Rescher’s and Robert Brandom’s paraconsistent logic on applied to Eastern philosophy by Graham Priest, dialethic logic. One can also compare Pai-chang’s Zen monastic rules to the simultaneously developed ones of St. Benedict.

Several, both Western and Asian philosophers, have compared Chan Buddhist mysticism with that of Wittgenstein. Reinhardt May in Heidegger’s Hidden Sources has investigated influences of Heidegger’s readings of Helmut Wilhelm’s translations of Yi Qing and Dao De Jing. Eric Nelson, in his fascinating recent book has traced not only the recently more well-known use made by Heidegger, but also extensive use by Martin Buber, Hans Dreisch, and a number of less famous German philosophers of the early twentieth century.

Perhaps more controversial is the comparison made between the European medieval scholastics’ fusion of Christian ethics with Aristotelian cosmology and the medieval Chinese, so-called neo-Confucian scholastic fusion of Confucian ethics and politics with Daoist cosmology. One can compare the concept of li in the “neo-Daoist of dark learning” Wang Bi and more extensively in the neo-Confucians, most notably Xuzi, as Leibniz had suggested. Beyond parallels there have been provocative arguments that Buddhist means of argument, via the so-called Silk Road in Central Asia, issued in part of European scholastic technique. Certainly, a topic in early modern philosophy is Leibniz’s praise of the Yijing as binary arithmetic, and his claims about the similarity of Xuzi’s metaphysics and his own Monadology, with brief note of Nicholas Malebranche’s less insightful dialogue between a Chinese and a Christian philosopher.

In western political philosophy the appeals to the superiority of Chinese society to that of Europe, or at least the existence of a well ordered and moral society without the Biblical God, by figures such as Montesquieu, Voltaire, Quesnay, Leibniz, Christian Wolff, and others, both using “China as a Model for Europe” as Maverick’s book is entitled, or as a means of satirizing European supposed morals and justice. The Chinese legalists, who were doing behavioral political science and Malthusian population theory of history over two millennia before Western political theorists did so, could be noted in a course in social philosophy that includes behavior political science.

Leibniz’s praise of the Yi as well as his extensive claims of similarity of Xuzi’s Li and Chi to his own form, substance, and monads. Also, Leibniz’s efforts of support for the Jesuit attempt to incorporate Confucian ceremonies into Catholic mass, and the Rites Controversy, detailed by David Mungello and others, deserve coverage in Early Modern courses.

There is a fascinating work by the child psychologist Alison Gopnik on possible connections that may have been made by Hume during his most creative period at La Fleche, where Descartes had studied long before, with missionaries who were familiar with Asian thought, particularly one who had lived in Siam.

In German romantic philosophy we find relatively little sophisticated treatment of Chinese philosophy (Witness Goethe’s fragmentary treatment of China.) However, there was a great reception of Indian philosophy among the German romantics. Schlegel, Schelling, and others absorbed ideas from Hinduism, not to mention Schopenhauer’s use of Buddhism. (Sedlar gives an elementary survey). In late nineteenth century philosophy there is the growing sympathy of Ernst Mach for Buddhism, as well as Nietzsche’s disputed attitudes toward Asian philosophy. Interestingly, Nietzsche copiously annotated his copy of Mach’s Analysis of Sensations, and offered to dedicate his Genealogy of Morals to Mach.

In twentieth century philosophy there have been numerous works of varying quality noting similarities between Wittgenstein’s approach to metaphysical questions and Chan Buddhism. There also are a number or works comparing Alfred North Whitehead to Buddhism.

Despite the severe criticisms that have been made of some best-selling popular treatments of the topic, I think there are significant parallels between some of the interpretations of quantum mechanics and some traditional Asian philosophies. I once had a testy exchange in print with the physicist and writer Jeremy Bernstein on this topic. His Trumpian reply was “Yogic, Schmogic.” A few decades later he wrote appreciatively of the Dali Llama’s attempt to relate Buddhism to quantum philosophy.

An Open Future for Education in Philosophy

I realize that there is always the danger of superficial comparisons between very different systems of thought, but I believe that much of the work I mention is not guilty of this. I also, realize, as a non-specialist, I have mentioned mainly works of comparison from the sixties through the eighties, and many more fine-grained scholarly articles have been produced in the last two decades.

I look forward to the integration of non-western philosophy into the core of the standard history of philosophy sequence, not just by supplementing the two or four-year sequence of history of philosophy courses with non-Western philosophy courses, but by including non-Western philosophy in the content of the history of philosophy of each period.

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]

Derek E. Anderson’s (2017) identification and characterisation of conceptual competence injustice has recently met some resistance from Podosky and Tuckwell (2017). They have denied the existence of this new type of epistemic injustice on the grounds that the wronging it denotes may be subsumed by testimonial injustice: “instances of conceptual competence injustice can be accurately characterised as instances of testimonial injustices” (Podosky and Tuckwell 2017: 26). Additionally, they have questioned the reasons that led Anderson (2017) to distinguish this epistemic injustice from testimonial, hermeneutical and contributory injustices (Podosky and Tuckwell 2017: 26-30).

Criticising the methodology followed by Podosky and Tuckwell (2017) in their attempt to prove that conceptual competence injustice falls within testimonial injustice, Anderson (2018) has underlined that conceptual competence injustice is a structural injustice and a form of competence injustice –i.e. an unfair misappraisal of skills– which should be retained as a distinct type of epistemic injustice because of its theoretical significance and usefulness. Causal etiology is not a necessary condition on conceptual competence injustice, he explains, and conceptual competence injustice, as opposed to testimonial injustice, need not be perpetrated by social groups that are negatively biased against a particular identity.

The unjust judgements giving rise to it do not necessarily have to be connected with testimony, even though some of them may originate in lexical problems and mistakes in the linguistic expressions a speaker resorts to when dispensing it. Accordingly, testimonial injustice and conceptual competence injustice may be said to be different kinds of injustice and have diverse effects: “It is not necessary that a person’s testimony be disbelieved, ignored, or pre-empted in an episode of CC [conceptual competence] injustice. CC injustice involves only an unjust judgment about a person’s ability to think well using certain concepts” (Anderson 2018: 31).

Welcoming the notion of conceptual competence injustice, I suggested in a previous contribution (Padilla Cruz 2017a) that it could be borrowed by the field of linguistic pragmatics in order to conceptualise an undesired perlocutionary effect of verbal interaction: misappraisals of a speaker’s actual conceptual and lexical abilities as a result of lack or misuse of vocabulary. Relying on Sperber and Wilson’s (1986/1995) description of intentional-input processing as a relevance-driven activity and of comprehension as a process of mutual parallel adjustment, where the mind carries out a series of incredibly fast simultaneous tasks that depend on decoding, inference, mindreading and emotion-reading, I also showed that those misappraisals result from deductions. A speaker’s alleged unsatisfactory performance makes manifest assumptions regarding her[1] problems with words, which are fed as weakly implicated premises to inferential processes and related to other detrimental assumptions that are made salient by prejudice.

In so doing, I did not purport to show, as Podosky and Tuckwell wrongly think, “how epistemic injustice manifests in the field of relevance theory” (2017: 23) or that “conceptual competence injustice is particularly useful in a relevance theoretical model of linguistic pragmatics” (2017: 30). Rather, my intention was to propose introducing the notion of conceptual competence injustice into general linguistic pragmatics as a mere way of labelling a type of prejudicial implicature, as they themselves rightly put it (Podosky and Tuckwell 2017: 30). The derivation of that sort of implicature, however, can be accounted for –and this is where relevance theory comes into the picture– on the basis of the cognitive processes that Sperber and Wilson’s (1986/1995) framework describes and of its conceptual apparatus.

In another contribution (Padilla Cruz 2017b), I clarified that, as a cognitive pragmatic framework, relevance theory (Sperber and Wilson 1986/1995) is concerned with the processing and comprehension of the verbal and non-verbal intentional stimuli produced in human communication. It very satisfactorily explains how hearers forge interpretative hypotheses and why they select only one of them as the plausibly intended interpretation. Relevance theorists are also interested in the generation of a variety of effects –e.g. poetic (Pilkington 2000), humorous (Yus Ramos 2016), etc.– and successfully account for them.

Therefore, the notion of conceptual competence injustice can only be useful to relevance-theoretic pragmatics as a label to refer to one of the (pernicious) effects that may originate as a consequence of the constant search for optimal relevance of intentional stimuli. I will not return to these issues here, as I consider them duly addressed in my previous contribution (Padilla Cruz 2017b).

My aim in this reply is to lend support to Anderson’s (2017) differentiation of conceptual competence injustice as a distinct type of epistemic injustice. I seek to argue that, ontologically and phenomenologically, conceptual competence injustice must be retained in the field of social epistemology as a helpful category of injustice because it refers to a wronging whose origin and scope, so to say, differ from those of testimonial injustice. Testimonial injustice stems from (mis)judgements pertaining to the output of an action or epistemic practice wherein epistemic agents may participate or be engaged. The action in question is giving testimony and its output is the very testimony given. The scope of testimonial injustice, therefore, is the product, the result of that action or epistemic practice.

In other words, testimonial injustice targets the ability to generate an acceptable product as a consequence of finding it not to satisfy certain expectations or requirements, or to be defective in some dimensions. In contrast, conceptual competence injustice denotes an unfairness that is committed not because of the output of what is done with words –i.e. informing and the dispensed information– but because of the very linguistic tools wherewith an individual performs that action –i.e. the very words that she makes use of– and supposed underlying knowledge. To put it differently, the scope of conceptual competence injustice is the lexical items wherewith testimony is dispensed, which lead prejudiced individuals to doubt the conceptual and lexical capacities of unprivileged individuals.

In order to show that the scopes of testimonial and conceptual competence injustices vary, I will be drawing from the seminal and most influential work on communication by philosopher Herbert P. Grice (1957, 1975).[2] This will also encourage me to suggest that the notion of testimonial injustice (Fricker 2003, 2007) could even be refined and elaborated on. I will argue that this injustice may also be perpetrated when a disadvantaged individual is perceived not to meet requirements pertaining to testimony other than truthfulness.

Content Characteristics or Requirements of (Good) Testimony

As an epistemic practice, dispensing testimony, or information, could be characterised, along Grice’s (1959, 1975) lines, as a cooperative activity. Testimony is given because an individual may be interested in imparting it for a variety of reasons –e.g. influencing others, appearing knowledgeable, contradicting previous ideas, etc.– and/or because it may benefit (an)other individual(s), who might (have) solicit(ed) it for another variety of reasons –e.g. learning about something, strengthening ideas, changing his worldview, etc. As an activity that brings together various individuals in joint action, providing testimony is subject to certain constraints or requirements for testimony to be properly or adequately dispensed. Let us call those constraints or requirements, using philosopher John L. Austin’s (1962) terminology, felicity conditions.

Some of those felicity conditions pertain to the individuals or interlocutors engaged in the epistemic practice. The dispenser of testimony –i.e. the speaker or informer– must obviously possess certain (true) information to dispense, have the ability to impart it and pursue some goal when giving it. In turn, the receiver of testimony should, but need not, be interested in it and make this manifest by explicit mention or elicitation of the testimony.

Other felicity conditions concern the testimony to be provided. For instance, it must be well supported, reliable and trustworthy. This is the sort of testimony that benevolent and competent informers dispense (Wilson 1999; Sperber et al. 2010), and the one on which the notion of testimonial injustice focuses (Fricker 2003, 2007). Making use again of Grice’s (1957, 1975) ideas, let us say that, for testimony to be appropriately imparted, it must satisfy a requirement of truthfulness or quality. Indeed, the maxim of quality of his Cooperative Principle prompts individuals to give information that is true and to refrain from saying falsehoods or things for which they lack adequate evidence.

But not only must testimony be truthful; for it to be properly dispensed, the information must also be both sufficient and relevant. Imagine, for instance, that someone was requested to tell the story of Little Red Riding Hood. For the narration to be complete, it should not only include details about who such a character was, where she lived, the fact that she had a grandmother who lived at some distance in the countryside, her grandmother’s conditions or their relationship, but also about what had happened to Little Red Riding Hood’s grandmother one day before receiving her visit and what happened to Little Red Riding Hood upon finding the wolf lying on the bed, disguised as the grandmother.

If the narrator mentioned the former details but omitted the latter, her narration, regardless of the fact that what she said about the characters’ identity and residence was undeniably true, would not be fully satisfactory, as it would not contain enough, necessary or expected information. Her testimony about Little Red Riding Hood would not be considered sufficient; something –maybe a key fragment– was missing for the whole story to be known, correctly understood and appraised.

Imagine now that all the details about the characters, their residence and relationship were present in the narration, but, upon introducing the wolf, the narrator started to ramble and talked about the animal spices wolves belong to, their most remarkable features, the fact that these animals are in danger of extinction in certain regions of Europe or that they were considered to have magical powers in a particular mythology. Although what the narrator said about the three characters is unquestioningly true and the story itself is told in its entirety, it would not have been told in the best way possible, as it includes excessive, unnecessary and unrelated information.

Again, along Gricean (1957, 1975) lines, it may be said that testimony must meet certain requirements or satisfy certain expectations about its quantity and relation. Actually, while his maxim of quantity incites individuals to give the expected amount of information depending on the purpose of a communicative exchange and prevents them from retaining or omitting expected or indispensable information, his maxim of relation causes them to supply information that is relevant or connected with the purpose of the exchange. Even if the provided information is true, failure to satisfy those requirements would render it inadequately given.

To the best of my knowledge, the notion of testimonial injustice as originally formulated by Fricker (2003, 2007) overlooks these requirements of quantity and relation, which solely pertain to the content of what is said. Accordingly, this injustice could also be argued to be amenable to be inflicted whenever an informer imparts unreliable or not well-evidenced information, and also when she fails to add necessary information or mentions irrelevant details or issues. If she did so, her ability to appropriately dispense information could be questioned and she could subsequently be downgraded as an informer.

Manner Characteristics or Requirements of (Good) Testimony

Testimony may be claimed to be adequately given when it is true, sufficient and relevant, but there are additional requirements that testimony should meet for it to be adequately imparted. Namely, the information must be presented in an orderly, clear and unambiguous way. How would you react if, when being told the story of Little Red Riding Hood, your interlocutor gave you all the necessary, relevant and true details –and nothing more– but she changed the order of the events, did not make it clear whom the wolf attacked firstly or what Little Red Riding Hood put in her basket, or resorted to unusual, difficult or imprecise lexical terms? Probably, you would say that the story was told, but many issues would not be crystal clear to you, so you would have difficulties in having a clear picture of how, when and why the events in the story happened.

Testimony may also be considered to be well dispensed when it is given in a good manner by correctly ordering events and avoiding both obscurity and ambiguity of expression. Order, clarity and ambiguity are parameters that do not have to do with what is said –i.e. the content– but with how what is said is said –i.e. its linguistic form. Accordingly, testimony may be asserted to be correctly imparted when it meets certain standards or expectations that only concern the manner in which it is given.[3] Some of those standards or expectations are connected with the properties of the linguistic choices that the speaker makes when wording or phrasing testimony, and others are determined by cultural factors.

For example, for a narration to count as a fairy tale, it would have to begin with the traditional and recurrent formula “Once upon a time” and then proceed by setting a background that enables identification of characters and situates the events. Similarly, for an essay to be regarded as a good, publishable research paper, it must contain, in terms of structure, an abstract, an introductory section where the state of the art of the issue to be discussed is summarised, the goals of the paper are stated, the thesis is alluded to and, maybe, the structure of the paper is explained.

Then, the essay must unfold in a clear and logically connected way, through division of the contents in various sections, each of which must deal with what is referred to in its heading, etc. In terms of expression, the paper must contain technical or specialised terminology and be sufficiently understandable. Many of these expectations are motivated by specific conventions about discourse or text genres.

Inability or failure to present information in the appropriate manner or to comply with operative conventions may also incite individuals to challenge an informer’s capacity to dispense it. Although the informer may be credited with being knowledgeable about a series of issues, she may be assessed as a bad informer because her performance is not satisfactory in terms of the linguistic means she resorts to in order to address them or her abidance by governing conventions. However, since such an assessment is motivated not by the quality, quantity or relation of the content of testimony, but by the tools with and the way in which the informer produces her product, its scope or target is obviously different.

Different Scopes, Distinct Types of Epistemic Injustice

The current notion of testimonial injustice only takes into account one of the three features of (well dispensed) testimony alluded to above: namely, quality or truthfulness. A more fine-grained conceptualisation of it should also consider two other properties: quantity and relation, as long as informers’ capacity to provide testimony may be doubted if they failed to give expected information and/or said irrelevant things or added unnecessary details. Indeed, quality, quantity and relation are dimensions that are connected with the content of the very information dispensed –i.e. what is said– or the product of the epistemic practice of informing. Testimonial injustice, therefore, should be characterised as the epistemic injustice amenable to be inflicted whenever testimony is found deficient or unsatisfactory on the grounds of these three dimensions pertaining to its content.

What happens, then, with the other requirement of good testimony, namely, manner? Again, to the best of my knowledge, Fricker’s (2003, 2007) description of testimonial injustice does not refer to its likely perpetration when an individual is judged not to impart testimony in an allegedly right manner. And, certainly, this characteristic of good testimony may affect considerations about how suitably it is given.

Dispensing information in a messy, obscure and/or ambiguous way could be enough for degrading an individual as informer. She could sufficiently talk about true and relevant things, yes, but she could say them in an inappropriate way, thus hindering or impeding understanding. Should, then, the manner in which testimony is provided be used as grounds to wrong an informer or to question a person’s capacities as such? Although the manner in which testimony is imparted may certainly influence assessments thereof, there is a substantial difference.

Failure to meet requirements of quality, quantity and relation, and failure to meet requirements of manner are certainly not the same phenomenon. The former has to do with the content of what is said, with the product or result of an activity; the latter, in contrast, as the name indicates, has to do with the way in which what is said is actually said, with the tools deployed to accomplish the activity. Testimony may be incorrectly dispensed because of its falsity, insufficiency or irrelevance, but it may also be inappropriately imparted because of how it is given –this is undeniable, I would say.

The difference between quality, quantity and relation, on the one hand, and manner, on the other hand, is a difference of product and content of that product, on the one hand, and tools to create it, on the other hand. Accordingly, testimonial injustice and conceptual competence injustice should be kept apart as two distinct types of epistemic injustice because the respective scopes of the judgements where each injustice originates differ. While in the former the issue is the content of testimony, in the latter what is at stake is the means to dispense it, which unveil or suggest conceptual deficits or lack of mastery of certain concepts.

Testimony is dispensed by means of linguistic elements that somehow capture –or metarepresent, in the specialised cognitive-pragmatic terminology (Wilson 1999; Sperber 2000)– the thoughts that a speaker entertains, or the information that she possesses, and is interested in making known to an audience. Such elements are words, which are meaningful units made of strings of recognisable sounds –i.e. allophones, or contextual realisations of phonemes, in the terminology of phonetics and phonology– which make up stems and various types of morphemesprefixes, infixes and suffixes– conveying lexical and grammatical information. More importantly, words are arranged in more complex meaningful units –namely, phrases– and these, in turn, give rise to larger, and still more meaningful, units –namely, clauses and sentences. Manner is connected with the lexical units chosen and their syntactic arrangements when communicating and, for the sake of this paper, when providing testimony.

Speakers need to constantly monitor their production and their interlocutors’ reactions, which often cause them to revise what they have just said, reformulate what they are saying or are about to say, expand or elaborate on it, etc. As complex an activity as speaking is, it is not exempt of problems. At a lexical level, the speaker may fail to use the adequate words because she misses them or has trouble to find them at a particular time for a variety of factors –e.g. tiredness, absentmindedness, etc. (Mustajoki 2012). The chosen words may also diverge from those normally used by other language users in order to refer to particular concepts. This happens when speakers have mapped those concepts onto different lexical items or when they have mapped those concepts not onto single words, but onto more complex units like phrases or even whole sentences (Sperber and Wilson 1997).

The selected terms may alternatively be too general, so the audience somehow has to inferentially adjust or fine-tune their denotation because of its broadness. Consider, for example, placeholders like “that thing”, “the stuff”, etc. used to refer to something for which there is a more specific term, or hypernyms like ‘animal’ instead of the more precise term ‘duck-billed platypus’. Or, the other way round, the selected terms may be too specific, so the audience somehow has to inferentially loosen their denotation because of its restrictiveness (Carston 2002; Wilson and Carston 2007).

Think, for instance, of hyponyms like ‘doggie’ when used to refer not only to dogs, but also to other four-legged animals because of perceptual similarity –they have four legs– and conceptual contiguity –they are all animals– or ‘kitten’ when used to refer to other felines for the same reasons;[4] or imagine that terms like ‘wheel’ or ‘cookie’ were metaphorically applied to entities belonging to different, unrelated conceptual domains –e.g. the Moon– because of perceptual similarity –i.e. roundness.[5]

At a syntactic level, the linguistic structures that the speaker generates may turn out ambiguous and misleading, even though they may be perfectly clear and understandable to her. Consider, for instance, sentences like “I saw your brother with glasses”, where the ambiguity resides in the polysemy of the word ‘glasses’ (“pair of lenses” or “drinking containers”?) and the distinct readings of the fragment “your brother with glasses” (who wears/holds/carries the glasses, the hearer’s brother or the speaker?), or “Flying planes may be dangerous”, where the ambiguity stems from the competing values of the –ing form (what is dangerous, the action of piloting planes or the planes that are flying?).

At a discourse or pragmatic level, finally, speakers may be unaware of conventions governing the usage and meaning of specific structures –i.e. pragmalinguistic structures (Leech 1983)– such as “Can/Could you + verb”, whose pragmatic import is requestive and not a question about the hearer’s physical abilities, or unfamiliar with sociocultural norms and rules –i.e. sociopragmatic norms (Leech 1983)– which establish what is expectable or permitted, so to say, in certain contexts, or when, where, how and with whom certain actions may or should be accomplished or avoided.

Would we, then, say that testimony is to be doubted or discredited because of mistakes or infelicities at a lexical, syntactic or pragmatic level? Not necessarily. The information per se may be true, reliable, accurate, relevant and sufficient, but the problem resides precisely in how it is presented. Testimony would have been given, no doubt, but it would not have been imparted in the most efficient way, as the most appropriate tools are not used.

When lexical selection appears poor or inadequate; words are incorrectly and ambiguously arranged into phrases, clauses or sentences; (expected) conventionalised formulae are not conveniently deployed, or norms constraining how, when, where or whom to say things are not respected or are ignored, what is at stake is not an informer’s knowledge of the issues testimony may be about, but her knowledge of the very rudiments and conventions to satisfactorily articulate testimony and to successfully dispense it. The objects of this knowledge are the elements making up the linguistic system used to communicate –i.e. vocabulary– their possible combinations –i.e. syntax– and their usage in order to achieve specific goals –i.e. pragmatics– so such knowledge is evidently different from knowledge of the substance of testimony –i.e. its ‘aboutness’.

Real or seeming lexical problems may evidence conceptual gaps, concept-word mismatches or (highly) idiosyncratic concept-word mappings, but they may lead privileged individuals to question disadvantaged individuals’ richness of vocabulary and, ultimately, the concepts connected with it and denoted by words. If this happens, what those individuals attack is one of the sets of tools to generate an acceptable product, but not the content or essence of such a product.

Conceptual competence injustice, therefore, must be seen as targeting the tools with which testimony is created, not its content, so its scope differs from that of testimonial injustice. The scope of testimonial injustice is the truthfulness of a series of events in a narration is, as well as the amount of details that are given about those events and the relevance of those details. The scope of conceptual competence, in contrast, is knowledge and correct usage of vocabulary, and possession of the corresponding concepts.

Conceptual competence injustice focuses on a specific type of knowledge making up the broader knowledge of a language and facilitating performance in various practices, which includes informing others or dispensing testimony. Such specific knowledge is a sub-competence on which the more general, overarching competence enabling communicative performance is contingent. For this reason, conceptual competence injustice is a competence injustice, or an unfairness about a type of knowledge and specific abilities –conceptual and lexical abilities, in this case. And just as unprivileged individuals may be wronged because of their lack or misuse of words and may be attributed conceptual lacunae, occasional or constant syntactic problems and pragmatic infelicities may induce powerful individuals to misjudge those individuals as regards the respective types of knowledge enabling their performance in these areas of language.

Conclusion

Phenomenologically, testimonial injustice and conceptual competence injustice are perpetrated as a consequence of perceptions and appraisals whose respective scopes differ. In testimonial injustice, it is information that is deemed to be unsatisfactory because of its alleged veracity, quantity and relevance, so the informer is not considered a good knower of the issues pertaining to that testimony. In conceptual competence injustice, in contrast, it is the tools by means of which information is dispensed that are regarded as inappropriate, and such inappropriateness induces individuals to doubt possession and knowledge of the adequate lexical items and of their corresponding, supporting conceptual knowledge.

While testimonial injustice is inflicted as a result of what is said, conceptual competence injustice is perpetrated as a consequence of the manner whereby what is said is actually said. Consequently, at a theoretical level, testimonial injustice and conceptual competence injustice should definitely be kept apart in the field of social epistemology. The latter, moreover, should be retained as a valid and useful notion, as long as it denotes an unfairness amenable to be sustained on the grounds of the linguistic tools employed to dispense testimony and not on the grounds of the characteristics of the product generated.

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).
