Mark Schroeder‘s research in philosophy explores questions in normative ethics, metaethics, epistemology, the philosophy of language, and the history of philosophy, among other areas. His book Slaves of the Passions (OUP 2007) explores the relationship between normative reasons for action and individual psychological differences, and Being For (OUP 2008) and Noncognitivism in Ethics (Routledge 2010) explore expressivist metaethical theories in a constructive but critical spirit. He has been the recipient of the APA Article Prize for the best article published in philosophy in 2008 or 2009, and three of his articles have been honored as among the ten best philosophy papers published in their year by the Philosophers’ Annual. A sampling of his papers have been published as Explanation and Expression in Ethics, volumes 1 and 2 (OUP, 2014, 2015). He completed his BA at Carleton College in 2000 with majors in philosophy, mathematics, and economics, and his PhD in philosophy at Princeton in 2004, and taught for two years at the University of Maryland before coming to USC in 2006.
