Meet the Speaker: Michael Waddell
The current holder of the Edna and George McMahon Aquinas Chair in Philosophy is Michael M. Waddell, Ph.D.

Dr. Waddell received his Ph.D. in Medieval Philosophy and his Master of Medieval Studies from the University of Notre Dame after having been graduated summa cum laude from Cornell College with a Bachelor of Arts in Religion and History. Before coming to Saint Mary’s, he taught at Villanova University and Augustana University. Dr. Waddell has published articles in The Thomist, International Philosophical Quarterly, Nova et Vetera, Sapientia, Tópicos, The Lyceum, The Saint Anselm Journal, and Miscellanea Mediaevalia, and has edited a collection of essays entitled Restoring Nature: Essays in Thomistic Philosophy and Theology. He has delivered lectures at the University of Oxford, the University of Cambridge, St. Anselm College, and the University of Mississippi, read solicited papers for the Society for Medieval and Renaissance Philosophy and the Institute for Saint Anselm Studies, and presented his work at meetings of the American Catholic Philosophical Association, the American Philosophical Association, the Société Internationale pour l’Étude de la Philosophie Médiévale, the Patristic, Medieval and Renaissance Studies Conference, and the International Congress for Medieval Studies.
Dr. Waddell’s scholarly interests include Thomas Aquinas’s metaphysics (especially his doctrine of transcendental truth, goodness and beauty), his account of the human soul and of the human person more holistically understood, and the ways in which these two areas of Thomas’s thought—viz., his metaphysics and his anthropology—are interconnected. His current work examines the writings of Thomas Aquinas and the broader Catholic tradition for resources to advance our understanding and our responses to disabilities, including especially autism spectrum disorder.
