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 new book, Life is Hard, comes out from Riverhead Books (US) and Hutchinson Heinemann (UK), October 2022. Combining philosophy with personal essay, the book has chapters on infirmity, loneliness, grief, failure, injustice, absurdity – and hope.

My last book was Midlife: A Philosophical Guide. It 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.
