We are very pleased that Professor Matthew Silverstein has joined us as a Contributor. Matty is an Assistant Professor of Philosophy at NYU Abu Dhabi . He is interested in the foundations of ethics—the question of what, if anything, we can we 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. Welcome aboard, Matty!
