The title of this book might suggest that it is an essay dealing exclusively with themes in Aristotle’s Ethics, but this study by Reeve is actually a comprehensive analysis of themes in Aristotle’s biology, psychology, physics, metaphysics, and more. It encompasses Aristotle’s remarks on the generation of animals, through his teleological and hylomorphic physics, into his analysis of desiderative and rational (practical and theoretical) functions of human souls. Reeve weaves all of these themes together toward the final end and purpose of all things, namely, union with and contemplation of pure form—God. The end of all actions and activities of hylomorphic, sublunary substances is ultimately to shed their matter and be absorbed into ‘thought itself’ (God). When looking in this way at happiness, the human end, the apparent dichotomy of ‘action’ and ‘contemplation’ dissolves into one. Aristotle’s Physics, Ethics, and Metaphysics become united. Reeve displays awareness of all the most recent scholarship on Aristotle. His translations, interpretations, and explanations of difficult passages are lucid and convincing. This is one of the finest recent publications on Aristotle.
