Abstract
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.
