Ontology, or the Theory of Being

This volume steps in where many philosophy students have felt a gap—a clear, English‑language introduction to general metaphysics grounded in the Scholastic tradition. It aims to show that the age‑old questions of medieval thinkers are far from obsolete, translating their debates into the language of contemporary philosophy. By situating Aristotle’s moderate realism alongside the great Schoolmen, the book invites listeners to see the timeless relevance of these ideas.

The text walks through core topics such as potency and act, essence versus existence, individuation, the nature of substance and accident, and the various kinds of causes. Rather than getting lost in dense argumentation, it highlights each problem’s significance and how it connects to modern discussions, making the material approachable for newcomers while still offering depth for more seasoned scholars.

Designed as a true textbook, the author balances clear exposition with enough rigor to satisfy advanced study. Drawing on classic sources like the works of Thomas Aquinas and the Spanish scholar Urraburu, the treatment remains accessible, providing a solid foundation for anyone interested in the metaphysics of the schools.
