Metaphysics, the science of being as being, is the subject of this volume composed in honour of John F. Wippel, the Theodore Basselin Professor of Philosophy at the Catholic University of America, and an internationally prominent metaphysician and expert in medieval philosophy. Scholars present studies on key philosophical and historical issues in the field. Though varied, the investigations address three major metaphysical themes: the subject matter of metaphysics, metaphysical aporiae, and philosophical theology.

Robert Sokolowski considers the historical recapitulation of the phrase ""the science of being as being""; Dominic O'Meara focuses on the development of this science in late antiquity; Jan A. Aertsen asks why the medievals called it ""First Philosophy""; and Andreas Speer returns to the origins of metaphysical discourse for a better understanding of contemporary metaphysical issues.

Gregory T. Doolan examines difficulties concerning Aquinas's metaphysics of substance; Jorge Gracia looks to the tradition of scholastic philosophy to examine the individuality and individuation of race; and James Ross argues against the modal ontologies of the twentieth century, showing that metaphysical possibility depends on the existence of a free, divine creator.

Stephen F. Brown considers Godfrey of Fontaines on the role of metaphysics in revealed theology; John F. Wippel examines Aquinas on the ""preambles of faith,"" those doctrines presupposed by faith that can also be proven philosophically; Brian J. Shanley addresses Aquinas's philosophical views on providence; Eleonore Stump, looking to Aquinas as well, shows how God can be personally present to human beings; and Marilyn McCord Adams offers a metaphysical consideration of the Christian doctrine of resurrection.
