My work is on foundational topics in the philosophy of language and mind, such as the nature of meaning, the character of linguistic agency, and the normativity and objectivity distinctive of language and thought. I am also interested in broader questions regarding our nature as individuals whose thinking and acting are governed by the appreciation of reasons. I am especially concerned with the way in which the later work of Donald Davidson bears on these issues. I also have an interest in the later work of Ludwig Wittgenstein.
