Seamus O’Neill is Associate Professor of Ancient and Medieval Philosophy at The Memorial University of Newfoundland. He completed his doctoral dissertation in 2009 in the Department of Classics at Dalhousie University on St. Augustine’s Platonism under Professor Wayne J. Hankey. Dr. O’Neill’s main philosophical interests are Ancient and Medieval Philosophy generally, Metaphysics, and the Philosophy of Religion. His current research deals with Augustine and other thinkers such as Plotinus, Boethius, Aquinas, and Bonaventure and their relation to the Neoplatonic tradition, specifically concerning mediation and human and divine agency. He has published articles and book chapters on figures such as St. Augustine, Porphyry, Boethius, St. Anselm, and Dante, and on the history of Platonic thought, demonology, the problem of evil, and the relation of ancient and scholastic thought to contemporary philosophical trends. His current SSHRC grant is entitled, "Reconstructing the Demonology of St. Augustine" (2014-2017). Currently he is writing on the demonology of St. Thomas Aquinas and is preparing a book manuscript on the demonology of St. Augustine and its philosophical import. Dr. O’Neill regularly teaches undergraduate and graduate courses on Plato, Aristotle, Boethius, Dante, Neoplatonic thought, and the histories of Ancient and Medieval Philosophy, and has also taught courses on Greek and Roman myth and drama, and the Latin language.
