These volumes gather together the latest research from 40 of the world's most eminent Thomistic theologians and philosophers, in commemoration of the 800th anniversary of Thomas Aquinas's birth. To mark this anniversary, these scholars each prepared a chapter that is an original research study shared at a major international conference in September 2024. The volumes cover a wide range of both philosophical and theological topics, reflecting the breadth of Aquinas's own thought, and will be organized by subject matter. Together, these volumes will provide a compendium of outstanding research on the wide spectrum of Aquinas's thought, which we hope will have enduring value for the field, offering an opportunity to revisit the ongoing importance of the work of Thomas Aquinas today.

This volume is a tribute to Fr. John F. Wippel. Following the philosophical order that Aquinas might have adopted “had he chosen to write a Summa metaphysicae”—an order that Wippel himself lays out in his Metaphysical Thought of Thomas Aquinas—these essays unfold new research on some of the most intriguing topics in Aquinas’s metaphysics, from the most recent generation of scholars formed by Wippel’s pioneering work. The contributors address the discovery of being qua being via separation (Gregory T. Doolan), propter quid metaphysical demonstrations (Philip Neri Reese), the origins of the controversies about the real distinction between essence and esse (Mark Gossiaux), a defense of essence-realism as a key to the real distinction (David Twetten), the relationship of likeness and agency (Therese Scarpelli Cory), created form as act and potency (Stephen Brock), the variation of accidental forms (Gloria Frost), the possibility of angelic judgment (Francis Feingold), argumentation for the existence of God (Gaven Kerr), the propriety of “Qui Est” as a Divine Name (Brian Carl), ‘Beauty’ as a Divine Name (Michael Rubin), and God’s application of creaturely powers to action (Jason Mitchell).
