I teach philosophy at MIT, working mainly in ethics, epistemology, and the philosophy of mind. I am the author of Practical Knowledge, Reasons without Rationalism, and Knowing Right From Wrong.
​
My self-help book, Midlife, is available in bookstores and can be ordered online. It has been reviewed in the Economist, ​the Spectator, the Guardian, the LA Review of Books, and the New Yorker, and was a Times Higher Education Book of the Week.

My work on midlife has been featured in Aeon, Hi-Phi Nation, Five Books, and the New York Times. I have also written about baseball and philosophy, H. P. Lovecraft, stand-up comedy, and the meaning of life.

I am currently working on a book about philosophy and adversity, forthcoming from Riverhead Books (US) and Hutchinson Heinemann (UK).
