Current Research

My research centers on a strongly naturalistic approach to good thinking. How can physical creatures - biological or artificial - think better? This involves issues in normative epistemology (what is it to think better?), philosophy of mind (what is it for a physical system to think in the first place?), and cognitive science (how do we humans manage to think well much of the time, and how might we teach machines to do it?). I also study related topics such as inference to the best explanation, formal models of simplicity, information theory, conceptual analysis, and the emotions.
