I work on a lot of different topics, including these the limits of what is possible, the structure of space and time, parts and wholes, things and their properties, evidence, belief, knowledge, and action.
I am currently working on issues in decision theory and ethics involving large and infinite numbers.
Most of my work applies technical tools to traditional philosophical questions.

TeachingI regularly teach Philosophy 450 (The Limits of Logic), which is about the limits of what can be said, proven, calculated, or counted. We study deep human discoveries about the infinite, the indescribable, and the impossible. If you've taken intro logic (or suitable courses in math, computer science, or linguistics) and you're interested in taking 450, contact me.
I've been working on a new textbook for this class. Here's a draft.
I also regularly teach graduate seminars and undergraduate classes in metaphysics, epistemology, philosophy of religion, philosophy of language, and philosophy of math.
