About Me

I am Professor of Philosophy at the Ohio State University. My CV is here. My email address is declan.smithies@gmail.com.

Research Interests

I work mainly in epistemology, the philosophy of mind, and the intersection between these two areas. I have just finished a book on the epistemic role of consciousness. I am currently working on papers on moral knowledge, the rationality of mind, and spatial perception.
