ABSTRACT

So-called basic self-knowledge (ordinary knowledge of one’s present states of mind) can be seen as both ‘baseless’ and privileged. The spontaneous self-beliefs we have when we avow our states of mind do not appear to be formed on any particular epistemic basis (whether introspective or extrospective). Nonetheless, on some views, these self-beliefs constitute instances of (privileged) knowledge. We are here interested in views on which true mental self-beliefs have internalist epistemic warrant that false ones lack. Such views are committed to a form of disjunctivism about basic self-knowledge. We begin by presenting an influential disjunctivist view about perceptual knowledge (Pritchard 2008, 2012, and elsewhere) and articulate a problem for it. We then consider two versions of disjunctivism about basic self-knowledge—one ‘constitutivist’, the other ‘neo-expressivist’—and argue that both can avoid an analog of this problem for self-knowledge. However, we give reasons for preferring the disjunctivism yielded by neo-expressivism. We conclude by considering briefly whether an acceptable disjunctivism about mental self-beliefs can point the way toward a sensible disjunctivism about perceptual beliefs.
