On some intracranialist dogmas in epistemology

Abstract

Abstract Research questions in mainstream epistemology often take for granted a cognitive internalist picture of the mind. Perhaps this is unsurprising given the seemingly safe presumptions that (i) knowledge entails belief (viz. the entailment thesis) and that (ii) the kind of belief that knowledge entails supervenes exclusively on brainbound cognition. It will be argued here that (contra orthodoxy) the most plausible version of the entailment thesis holds just that knowledge entails dispositional belief. However, regardless of whether occurrent belief supervenes only as the cognitive internalist permits, we should reject the idea that dispositional belief supervenes only in cognitive internalist-friendly ways. These observations, taken together, reveal two things: first, that a cognitive internalist picture of the mind is much more dispensable in epistemology than has been assumed and, second, that pursuing questions in extended epistemology need not involve any radical departure from the commitments of more traditional epistemological projects.
