Part Two
In
his paper, Christopher Pincock gives two arguments that he says demonstrate that someone who adopts a realist epistemic stance
must do so, on pain of incoherence.
The realist should reject voluntarism about stances, and so insist that their stance is tied to theoretical reasons. . . . My suggestion is that the realist should maintain that their realist stance is rationally obligatory. How might this defense go? — Pincock, 7
I’ll try to lay out the first argument in this Part Two, while pointing out that Pincock himself does a very good job, and it’s worth reading this in its entirety rather than my paraphrase.
First, a preliminary point which I’ve raised before. We can say that, for Pincock, the term “theoretical reasons” is essentially equivalent to “reasons that are rationally obligatory.” And we know that Chakravartty objects to this characterization, claiming that it begs the question against the very idea of stance voluntarism: “On the voluntarist view, rational choice and rational obligation are distinct concepts and cannot be run together.”
So let’s keep this dispute in mind, in what follows.
Pincock’s first argument is a reductio designed to show that, if an epistemic realist takes the position that their stance is
not obligatory, they will arrive at “pragmatic incoherence.” Therefore, they should claim that realism is obligatory.
To set this up, Pincock describes a typical instance of inference to the best explanation (IBE), which characterizes the kind of inference he believes realists can and should draw. This involves an account of Benjamin Franklin’s famous experiment with kite, key, and lightning. The realist will say that Franklin concluded that “lightning is an electrical discharge” (call this L) because he had a
reason for so concluding. He needed to understand that his evidence is evidence
for L. He needed to grasp a principle of inference that can link his evidence with L.
Pincock distinguishes Franklin’s epistemic stance from another one that Franklin might have taken. He might have said, “I’m disposed to claim to know L when I have this kind of evidence. It’s just what I do, or what seems best to me; others may do differently.” For Pincock, this wouldn’t give Franklin
reasons for his claim that L. Pincock asks us to imagine how this “non-theoretical” Franklin would respond to a challenge to his claim about L: He has nothing at his disposal that would count as a reason for others to adopt, so he would have to be silent in the face of his challengers. The actual Franklin, though, scientific realist that he was, can reply with an account that involves how evidence is connected to knowledge claims. This account will not necessarily carry the day, nor will it have to result in an indisputable knowledge claim, but it does consist of alleged reasons for beliefs that are meant to be convincing for anyone, not just statements about “how I proceed when I see X and Y.”
Now, here is the core of Pincock’s incoherence argument, in which he asks us to imagine a realist who does
not believe that their epistemic stance is obligatory:
A realist who is also a voluntarist about stances will admit to their own realist stance, but also allow that there is no reason that obliges them to adopt that realist stance. Consider a claim to knowledge that the realist advances on the basis of their evidence and their realist stance, such as Franklin’s L. A realist who is also a voluntarist about stances and who reflects on this situation is immediately landed in a pragmatically incoherent situation. . . . First, they put forward the claim L as something they believe to be true. Second, they are aware that this belief is due in part to their realist stance. Third, as a voluntarist about stances, they admit that they have not adopted their realist stance on the basis of any reasons that reflect the truth.
As we have seen, the voluntarist explains the adoption of a stance by appeal to the person’s desires and values. If these desires and values have no connection to the truth, then the realist must admit that their resulting beliefs are not appropriately connected to the truth, and so not known. . . . The realist must admit to themselves that they know they could acquire this belief whether it was true or not. This is the pragmatic incoherence: by the realist’s own lights, one of their beliefs, which they take to be true, is also something that they admit to themselves that they would have whether it was true or not. The only way to restore coherence and to maintain one’s voluntarism about one’s stance is to withdraw any claim to know that is based on one’s stance. For the realist, this means abandoning their realism. — Pincock, 5-6
There are a number of issues raised by this argument, which Pincock discusses carefully. One, inspired by Bernard Williams, concerns whether one can actually “acquire a belief” without believing it to be true. Another concerns whether such a question applies only at the level of doxastic belief, not the choice of epistemic stance.
But I’ll cut to the chase and say that I think the argument as a whole can be defeated simply by denying the characterization of what a stance voluntarist does. Pincock’s language includes phrases such as “no reason that obliges them,” “not adopt[ing] their realist stance on the basis of any reasons that reflect the truth,” “no connection to the truth,” and “not appropriately connected to the truth.” These all-or-nothing characterizations can only hold water if we accept Pincock’s idea that a theoretical reason
must result in rational obligation. (I should point out that the first phrase, “no reason that
obliges them,” would be conceded by Chakravartty. But he would not concede that there are no theoretical reasons that could
have a bearing, or
influence the decision – merely that they don’t result in rational obligation, and that others could have different reasons for their stances, or weight them differently.)
As we know, Pincock maintains that the stance voluntarist has
no theoretical reasons of any sort for their adoption of a stance. For Pincock, only “desires and values” can form the basis for (voluntarily) adopting a stance. Once again, if we look back at Chakravartty’s description of how he understands an epistemic stance, this seems to be a misreading:
An epistemic stance is an orientation, a collection of attitudes, values, aims, and other commitments relevant to thinking about scientific ontology, including policies or guidelines for the production of putatively factual beliefs . . . — Chakravartty, 1308
Or perhaps it’s not so much a misreading as an interpretation which claims that,
if all theoretical reasons create obligations,
then everything on Chakravartty’s list has to be something else, since Chakravartty is claiming to be a stance voluntarist. It may also be a sort of challenge: If this list is
not merely disguised “desires and values,” then tell us directly what the theoretical element is. What “other commitments” do you have in mind?
In any case, Chakravartty’s response to the incoherence argument is straightforward:
Let me generalize this contention [that stance voluntarism is inconsistent with realism] in a way that I believe Pincock would accept, by parity of reasoning: in this case (ex hypothesi) no one would have a reason to adopt their own or any other rational stance – the concern presumably applies across the board – because there is no rational obligation to go one way or another. Lacking rational obligations and recognizing the rationality of those with conflicting stances, it would be indefensible, incoherent even, to adopt any such option. — Chakravartty, 1311-12
The epistemic realist, of course, wants to say that this argument applies only against other stances; there is something unique about the stance supported by strictly “theoretical” reasons. Chakravartty says that the only way this could be made compelling is by accepting the conflation of rational choice with rational obligation, which, as we’ve noted, seems to beg the question against the voluntarist:
The very idea that a given stance must be rationally obligatory to be rationally chosen is precisely what stance voluntarism denies. . . . On the voluntarist view, rational choice and rational obligation are distinct concepts and cannot be run together. — Chakravartty, 1312
And Chakravartty points out what we’ve alluded to several times now: a non-question-begging argument would have to start with an understanding of rationality that precludes alternative rational standards completely:
But this would require something more than what has been provided [by Pincock]: a compelling argument for . . . a theory of rationality in light of which such a demonstration could be given. This, however, is a tall order. — Chakravartty, 1312
In fact, Pincock does offer such an argument, which I’ll look at in Part Three. But for now, do you agree that the pragmatic-incoherence argument requires this “tall order” if it’s going to go through in a non-question-begging way? I believe Chakravartty is right about this.
