 As shown in this work, Suárez has a conception of metaphysics which initially seems much more narrowly focused than that subject as it is conceived today. Still, even given this narrower concentration, metaphysics as practiced by Suárez opens itself into many of the topics commanding the attention of current day metaphysicians. His avowedly narrow focus results from his taking metaphysics to have but one, exclusive object: “the study of being insofar as it is real being” (DM I  1.26).[8]  In this sense, Suárez understands metaphysics in a broadly Aristotelian manner as the study of being and its causes. This study was rechristened in the seventeenth century as  “ontology”,[9]  literally, the study of to on, or being, in view of the then broadening sweep of metaphysics whereby it came to include the investigation of minds and bodies, causation, numbers, identity and other relations, properties and propositions, modality, and, eventually, the nature of abstract entities, including fictional ones. Relative to this broader conception, ontology, as the study of being, seems highly specific. Still, this appearance is misleading, especially where Suárez is concerned, since he addresses most of the topics on this list in one way or another, if in an idiom alien to those unschooled in Aristotelianism. For, as it turns out, he understands “the study of being” and its causes very broadly indeed.
