Rebecca DeYoung (Ph.D. University of Notre Dame) has enjoyed teaching ethics and the history of ancient and medieval philosophy at Calvin College for the past 20 years. Her research focuses on the seven deadly sins, as well as Thomas Aquinas’s work on virtue. Her books include Glittering Vices (Brazos), Vainglory (Eerdmans), and a co-authored volume entitled Aquinas’s Ethics (University of Notre Dame Press). Recent essays about various vices and virtues—hope, despair, sloth, courage, magnanimity, and vainglory—appear in Virtues and Their Vices (Oxford), Being Good (Eerdmans), and Cambridge Critical Guide to Aquinas’s De Malo, and the journals Res Philosophica, ACPQ, the Thomist, and Faith and Philosophy. Awards for her work include the Book and Essay Prize from the Character Project and the C.S. Lewis prize for Glittering Vices. She speaks widely, including opportunities to teach in prison. She and her husband live in Grand Rapids, near the beautiful Lake Michigan shoreline. They have four children ages 13-20.
