This book will remain timeless in its study of Aristotle's objective grasp of reality. The book's uniqueness lies in its aim of letting Aquinas himself speak on the subject of metaphysics. The work embraces both a history of philosophy and Aristotle's subsequent reasoning toward God as pure act. Readers will find a summary of the wealth of insight of Aristotle, further elaborated by Aquinas. Metaphysics of Aquinas will appeal to both graduate and undergraduate students and scholars of metaphysics.
