Matthew Silverstein is interested in the foundations of ethics—the question of what, if anything, we can say on behalf of our most basic ethical commitments? His secondary philosophical interests include the philosophy of action, political philosophy, early modern philosophy, and the history of ethics. He is the author of In Defense of Happiness: A Response to the Experience Machine, published in Social Theory and Practice. Silverstein teaches courses on tolerance and relativism, ethics and modern European philosophy. Before joining NYUAD, Silverstein was a visiting professor at Amherst College in Massachusetts, where he taught courses on early modern philosophy, ethics, and the nature of morality. As a doctoral student at the University of Michigan, he won a prize for excellence in teaching and was the recipient of numerous fellowships. Silverstein has served for four years as a panelist for AskPhilosophers.org, a website that puts the knowledge and talents of professional philosophers at the service of the general public, who pose philosophical questions for the panelists to consider. Silverstein holds a Ph.D. from the University of Michigan in Ann Arbor, a B.Phil. from the University of Oxford, UK, and a B.A. from Amherst College.
