In this groundbreaking work, C. D. C. Reeve uses a fundamental problem--the Primacy Dilemma--to explore Aristotle's metaphysics, epistemology, dialectic, philosophy of mind, and theology in a new way. At a time when Aristotle is most often studied piecemeal, Reeve attempts to see him both in detail and as a whole, so that it is from detailed analysis of hundreds of particular passages, drawn from dozens of Aristotelian treatises, and translated in full that his overall picture of Aristotle emerges. Primarily a book for philosophers and advanced students with an interest in the fundamental problems with which Aristotle is grappling, Substantial Knowledge's clear, non-technical and engaging style will appeal to any reader eager to explore Aristotle's difficult but extraordinarily rewarding thought.
