I am Chancellor Kent Professor of Law and History at Yale University.

I’m a historian of morality; at least, that’s how I think of myself. I’ve studied where ideas about morality come from and the philosophers who’ve propounded them. For the past decade or so, I’ve been interested in movements that try to make the world a better place: things like the human rights movement or the mobilisation to make war less cruel.
