"Aristotle's theory of substance is commonly viewed nowadays as an inconsistent amalgam of different accounts, developed at different times.". "In a clear and engaging style, C. D. C. Reeve's groundbreaking new book challenges this received view. Through careful analysis of passages drawn from dozens of works, it shows how Aristotle's metaphysics, epistemology, philosophy of mind, and theology work together to constitute a unified solution to a single fundamental, and hitherto inadequately appreciated, problem about substance."--BOOK JACKET.
