Professional Bio

My work began from methodological questions in the foundations of set theory, especially how new axioms can be properly criticized or defended.  (Click here for videos of our recent workshop on ‘Mathematical Depth, a notion central in a recent book, Defending the Axioms.)  This focused inquiry has led to more general questions in the metaphysics and epistemology of mathematics and logic, and the relations of these subjects to natural science.  Progress on all this seemed to me to require some attention to the methodology of philosophy itself; I’ve been especially interested in naturalism, but also logical positivism, ordinary language philosophy and its descendants, various ‘therapeutic’ approaches, conceptual analysis, etc. — and in radical skepticism as a diagnostic tool for comparing and contrasting these schools of meta-philosophical thought.  This is coupled with historical interest in such figures as Descartes, Locke, Berkeley, Hume, Reid, Kant, Frege, Wittgenstein, Moore, Austin, Carnap and Quine.  (For a recent overview, click here.)

These interests are reflected in upcoming and recent seminars:
