It is sometimes objected that anti-individualism, because of its assumption of the constitutive role of natural and social environments in the individuation of intentional attitudes, raises sceptical worries about first-person authority--that peculiar privilege each of us is thought to enjoy with respect to non-Socratic self-knowledge. Gary Ebbs believes that this sort of objection can be circumvented, if we give up metaphysical realism and scientific naturalism and adopt what he calls a “participant perspective” on our linguistic practices. Drawing on broadly Wittgensteinian (...) considerations, I argue that Ebbs is right about this, and I show how two likely objections to his view can be circumvented. I also argue that mere adoption of the participant perspective does not serve to refute external-world sceptic. (shrink)

In two previous papers I explained why I believe that a certain sort of argument that seems to support skepticism about self-knowledge is actually self-undermining, in the sense that no one can justifiably accept all of its premises at once. Anthony Brueckner has recently tried to show that even if the central premises of my explanation are true, the skeptical argument in question is not self-undermining. He has also suggested that even if the skeptical argument is self-undermining, it can still (...) serve as a _reductio ad absurdum of the assumption that we have self-knowledge. My goal in this paper is to explain why I think neither of these responses is successful. (shrink)

In this thesis, I elaborate and defend Donald Davidson's account of knowing one's own mental states that exhibit first-person authority. To that end, I place Davidson's account among others in the philosophical landscape concerning self-knowledge. Next, I examine his response to philosophical challenges that arise from mental content externalism and self-deception. Finally, I draw some insights froms Davidson's account to the broader aims of epsitemology.
