Selim Berker is Professor of Philosophy at Harvard University. His primary research interests are in ethics and epistemology, which he sees as two aspects of the same field—ethics being the study of what, if anything, we ought to do, and epistemology being the study of what, if anything, we ought to believe. He regularly teaches courses on the foundations of morality, on reasons and rationality, and on deflationary approaches to metaethics (such as nihilism and relativism), and he has published articles on epistemic consequentialism in Philosophical Review, on the normative irrelevance of neuroscience and empirical psychology in Philosophy & Public Affairs, and on moral particularism in Ethics. A lapsed physicist (Harvard A.B. 1998 summa cum laude, M.A. 2000), Berker received his Ph.D. in philosophy from M.I.T. in 2007 under the direction of Judith Jarvis Thomson. He is a recipient of the Phi Beta Kappa Prize for Excellence in Teaching, the Roslyn Abramson Award (for excellence in undergraduate teaching), an ACLS Fellowship, a Radcliffe Institute for Advanced Study Fellowship, and a Laurance S. Rockefeller Visiting Faculty Fellowship at Princeton’s University Center for Human Values.
