In this episode, David Finkelstein talks about his past and current work as well as his teaching interests. He begins by discussing some of his past work on first-person authority and expression, bringing this into relation to what Ludwig Wittgenstein has to say about mental self-ascription. Finkelstein then delves into a current project that explores consciousness and first-person awareness and their relation to expression. He begins from what might seem like a surprising starting point – John Locke's account of personal identity. Finally, Finkelstein, describing a course that he particularly likes teaching, discusses philosophical conceptions of wonder in connection with his interest in magic. David Finkelstein is Associate Professor in the Department of Philosophy at the University of Chicago.
