Rebecca DeYoung (Ph.D. University of Notre Dame) has enjoyed teaching ethics and the history of ancient and medieval philosophy at Calvin College for over 20 years.  Her research focuses on the seven deadly sins, and virtue ethics, as well as Thomas Aquinas’s work on the virtues.  Her books include Glittering Vices (Brazos, 2nd edition 2020), 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, wrath, and vainglory—appear in Virtues and Their Vices (Oxford), Being Good (Eerdmans), and Cambridge Critical Guide to Aquinas’s De Malo (Cambridge), 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 Scot live in Grand Rapids, near the beautiful Lake Michigan shoreline. They have four children ages 15-22.

Glittering Vices: A New Look at the Seven Deadly Sins and Their Remedies (Brazos, 2009).

read a review at the Church Connection blog

"Glittering Vices is a lucid, historically informed, and well-illustrated exploration of the seven deadly sins. DeYoung's book will unquestionably help teachers, students, and laypersons toward the Socratic and Christian goal of self-examination. This in an invaluable guide for anyone seeking self-understanding, spiritual growth, and philosophical insight."
–W. Jay Wood, Wheaton College

"Rebecca DeYoung gives us an in-depth, informing, and frequently fascinating look at the vices and why they glitter. For the believer, reading her words will become, in and of itself, an act of spiritual formation."
–Phyllis Tickle
