Aristotle classified the things in the world into ten categories: substance, quantity, quality, relative, etc. Plotinus, the founder of Neoplatonism, attacked the classification, accepting only these first four categories, rejecting the other six, and adding one of this own: change. He preferred Plato's classification into five kinds which included change. In this part of his commentary, Simplicius records the controversy on the six categories which Plotinus rejected: acting, being acted upon, being in a position, when, where, and having on. Plotinus' pupil and editor, Porphyry, defended all six categories as applicable to the physical world, even if not to the world of Platonic Forms to which Platonist studies must eventually progress. Porphyry's pupil, lamblichus, went further: taken in a suitable sense, Aristotle's categories apply also to the world of Forms, although they require Pythagorean reinterpretation. Simplicius may be closer to Porphyry that to lamblichus, and indeed Porphyry's defence established Aristotle's categories once and for all in Western thought. But the probing controversy of this period none the less revealed more effectively than any discussion of modern times the profound difficulties in Aristotle's categorical scheme.

This is one in a series of translations with introductions, copius notes and comprehensive indexes. It fills an important gap in the history of European thought.

This volume completes, starting from chapter 6, the commentary by the young Philoponus on Aristotle's Categories, of which chapters 1–5 were previously published in this series (Philoponus: On Aristotle Categories 1–5 with Philoponus: A Treatise Concerning the Whole and the Parts). This ancient commentary was the first work in the Aristotelian syllabus after a general introduction to Aristotle by the same author. It is influenced by an extant short anonymous record of Philoponus' teacher Ammonius' lectures on the same work, but Philoponus' commentary is two and a half times as long as that anonymous record, and includes special contributions of Philoponus' own, for example in philology, Christian theology and in disagreements with Aristotle. This English translation of Philoponus' work is the latest volume in the Ancient Commentators on Aristotle series and makes this philosophical work accessible to a modern readership. The translation is accompanied by an introduction, comprehensive commentary notes, bibliography, glossary of translated terms and a subject index.

Knowledge, Nature, and the Good brings together some of John Cooper's most important works on ancient philosophy. In thirteen chapters that represent an ideal companion to the author's influential Reason and Emotion, Cooper addresses a wide range of topics and periods--from Hippocratic medical theory and Plato's epistemology and moral philosophy, to Aristotle's physics and metaphysics, academic scepticism, and the cosmology, moral psychology, and ethical theory of the ancient Stoics. Almost half of the pieces appear here for the first time or are presented in newly expanded, extensively revised versions. Many stand at the cutting edge of research into ancient ethics and moral psychology. Other chapters, dating from as far back as 1970, are classics of philosophical scholarship on antiquity that continue to play a prominent role in current teaching and scholarship in the field. All of the chapters are distinctive for the way that, whatever the particular topic being pursued, they attempt to understand the ancient philosophers' views in philosophical terms drawn from the ancient philosophical tradition itself (rather than from contemporary philosophy). Through engaging creatively and philosophically with the ancient texts, these essays aim to make ancient philosophical perspectives freshly available to contemporary philosophers and philosophy students, in all their fascinating inventiveness, originality, and deep philosophical merit. This book will be treasured by philosophers, classicists, students of philosophy and classics, those in other disciplines with an interest in ancient philosophy, and anyone who seeks to understand philosophy in philosophical terms.

Evoquees par Augustin, les Categories d'Aristote, accompagnees de l'introduction de Porphyre, sont traduites et commentees par Boece. Deja exposee dans le monde arabo-musulman, cette oeuvre devait faire l'objet de nombreux commentaires dans le monde latin, sans interruption, du temps d'Abelard jusqu'a la fin du Moyen Age. De l'etude du langage a la theorie de l'etre, ouvrant sur la philosophie naturelle et la theologie, les interrogations que suscitent les Categories sont multiformes. Elles concernent le statut des categories, leur nombre, les differents types de predication, ou la nature particuliere de certaines categories comme la relation ou la quantite. Le premier chapitre du traite, avec sa distinction entre equivoques, univoques et paronymes, suscite des reflexions sur les variations semantiques, les transferts de sens, et donne en meme temps naissance a la theorie de l'analogie de l'etant, aux implications metaphysiques et theologiques majeures. Les vingt deux essais de ce receuil explorent, a travers l'etude d'auteurs connus ou moins connus, les multiples facettes de cette riche tradition medievale de commentaires sur les Categories d'Aristote.

Athenian and Alexandrian Neoplatonism and the Harmonization of Aristotle and Plato by I. Hadot deals with the Neoplatonist tendency to harmonize the philosophies of Plato and Aristotle. It shows that this harmonizing tendency, born in Middle Platonism, prevailed in Neoplatonism from Porphyry and Iamblichus, where it persisted until the end of this philosophy. Hadot aims to illustrate that it is not the different schools themselves, for instance those of Athens and Alexandria, that differ from one another by the intensity of the will to harmonization, but groups of philosophers within these schools.
