Forthcoming in A. Fairweather and O. Flanagan (eds.), Naturalizing Epistemic Virtue (Cambridge University Press).Consider the claim that openmindedness is an epistemic virtue, the claim that true belief is epistemically valuable, and the claim that one epistemically ought to cleave to one's evidence. These are examples of what I'll call "epistemic discourse." Here I'll propose and defend a view called "convention-relativism about epistemic discourse." In particular, I'll argue that convention-relativism is superior to its main rival, expressivism about epistemic discourse. Expressivism and convention-relativism both jibe with antirealism about epistemic normativity, which is motivated by appeal to philosophical naturalism ( §1). Convention-relativism says that epistemic discourse describes how things stands relative to a conventional set of "epistemic" values; such discourse is akin to criticism relative to the conventional rules of a club ( §2). I defend conventionrelativism by appeal to a "reverse open question argument," which says, pace expressivism, that epistemic discourse leaves normative questions open ( §3).My three examples of epistemic discourse (above) represent three species of epistemic discourse: (i) attributions of the property of being an epistemic virtue, or "epistemic virtue attributions," for short, (ii) attributions of the property of having epistemic value, or "epistemic value attributions," for short, and (iii) attributions of epistemic obligation.
1Epistemic virtue attributions and epistemic value attributions are species of epistemic evaluation; epistemic obligation attributions can be understood as non-evaluative.Epistemic discourse seems normative. I'll appeal to a more precise criterion of the normativity of discourse, below ( §3.1), but the following will suffice to motivate the idea that epistemic discourse seems normative. To say that openmindedness is an epistemic virtue seems to be to say that openmindedness really is a virtue, i.e. that it is good or desirable or admirable to be openminded; to say that true belief is epistemically valuable seems to be to say that true belief really is valuable, i.e. that true belief is good or worthy of pursuit or approbation; to say that one epistemically ought to cleave to one's evidence seems to be to say that one really ought to cleave to one's evidence, i.e. that one would (or at least could) deserve blame or censure or sanction for not so cleaving.
