Thomas Williams is Professor of Philosophy at the University of South Florida. He earned a B.A. in Philosophy from Vanderbilt University in 1988 and a Ph.D. in Philosophy from the University of Notre Dame in 1994. Before coming to USF he taught at the University of Iowa, where he received the College of Liberal Arts and Sciences Collegiate Teaching Award in 2005. He was Alvin Plantinga Fellow in the Center for Philosophy of Religion at Notre Dame in 2005-06. He was recently awarded the American Philosophical Association's Edinburgh Fellowship, which will enable him to be in residence at the Institute for Advanced Studies in Humanities at the University of Edinburgh in the Fall of 2014, and he will be a visiting fellow in the Centre for Ethics, Philosophy, and Public Affairs at the University of St Andrews in the Spring of 2015.

Dr Williams's research interests are in medieval philosophy and theology (especially Augustine, Anselm, Aquinas, and Duns Scotus) and the philosophy of religion. His recent work includes several contributions to edited volumes — "Human Freedom and Agency," Oxford Handbook of Thomas Aquinas (Oxford U P, 2011); "The Franciscans," Oxford Handbook of the History of Ethics (Oxford U P, 2013); "Anselm: Free Will and Moral Responsibility," Key Debates in Medieval Philosophy (Routledge, forthcoming); "Hermeneutics and Reading Scripture," Cambridge Companion to Augustine, 2nd ed. (Cambridge U P, forthcoming); "Anselm on Evil," The History of Evil in the Middle Ages (Acumen, forthcoming); "Atonement," Routledge Handbook of Medieval Philosophy (Routledge, forthcoming) — and an article on the response of American High Churchmen to the Oxford Movement (Anglican and Episcopal History, 2012). Current projects include a translation of Augustine's Confessions, a translation of and commentary on Thomas Aquinas's Treatise on Happiness and Treatise on Human Action (co-authored with Christina van Dyke of Calvin College), and John Duns Scotus: Readings in Ethics, for which he recently received a $138,000 grant from the National Endowment for the Humanities.
