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.

Philoponus' On Aristotle Categories 1-5 discusses the nature of universals, preserving the views of Philoponus' teacher Ammonius, as well as presenting a Neoplatonist interpretation of Aristotle's Categories. Philoponus treats universals as concepts in the human mind produced by abstracting a form or nature from the material individual in which it has its being. The work is important for its own philosophical discussion and for the insight it sheds on its sources. For considerable portions, On Aristotle Categories 1-5 resembles the wording of an earlier commentary which declares itself to be an anonymous record taken from the seminars of Ammonius. Unlike much of Philoponus' later writing, this commentary does not disagree with either Aristotle or Ammonius, and suggests the possibility that Philoponus either had access to this earlier record or wrote it himself. This edition explores these questions of provenance, alongside the context, meaning and implications of Philoponus' work. The English translation is accompanied by an introduction, comprehensive commentary notes, bibliography, glossary of translated terms and a subject index. The latest volume in the Ancient Commentators on Aristotle series, the edition makes this philosophical work accessible to a modern readership. Philoponus was a Christian writing in Greek in 6th century CE Alexandria, where some students of philosophy were bilingual in Syriac as well as Greek. In this Greek treatise translated from the surviving Syriac version, Philoponus discusses the logic of parts and wholes, and he illustrates the spread of the pagan and Christian philosophy of 6th century CE Greeks to other cultures, in this case to Syria. Philoponus, an expert on Aristotle's philosophy, had turned to theology and was applying his knowledge of Aristotle to disputes over the human and divine nature of Christ. Were there two natures and were they parts of a whole, as the Emperor Justinian proposed, or was there only one nature, as Philoponus claimed with the rebel minority, both human and divine? If there were two natures, were they parts like the ingredients in a chemical mixture? Philoponus attacks the idea. Such ingredients are not parts, because they each inter-penetrate the whole mixture. Moreover, he abandons his ingenious earlier attempts to support Aristotle's view of mixture by identifying ways in which such ingredients might be thought of as potentially preserved in a chemical mixture. Instead, Philoponus says that the ingredients are destroyed, unlike the human and divine in Christ. This English translation of Philoponus' treatise is the latest volume in the Ancient Commentators on Aristotle series and makes this philosophical work accessible to a modern readership. The translation in each volume is accompanied by an introduction, comprehensive commentary notes, bibliography, glossary of translated terms and a subject index.

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.

A state-of-the-art overview of ancient logic for students and scholars, with in-depth analyses of its central themes.

"Aristotle versus Plato. For a long time that is the angle from which the tale has been told, in textbooks on the history of philosophy and to university students. Aristotle's philosophy, so the story goes, was au fond in opposition to Plato's. But it was not always thus."—from the Introduction In a wide-ranging book likely to cause controversy, Lloyd P. Gerson sets out the case for the "harmony" of Platonism and Aristotelianism, the standard view in late antiquity. He aims to show that the twentieth-century view that Aristotle started out as a Platonist and ended up as an anti-Platonist is seriously flawed. Gerson examines the Neoplatonic commentators on Aristotle based on their principle of harmony. In considering ancient studies of Aristotle's Categories, Physics, De Anima, Metaphysics, and Nicomachean Ethics, the author shows how the principle of harmony allows us to understand numerous texts that otherwise appear intractable. Gerson also explains how these "esoteric" treatises can be seen not to conflict with the early "exoteric" and admittedly Platonic dialogues of Aristotle. Aristotle and Other Platonists concludes with an assessment of some of the philosophical results of acknowledging harmony.

This book provides a collection of sources, many of them fragmentary and previously scattered and hard to access, for the development of Peripatetic philosophy in the later Hellenistic period and the early Roman Empire. It also supplies the background against which the first commentator on Aristotle from whom extensive material survives, Alexander of Aphrodisias (fl. c. AD 200), developed his interpretations which continue to be influential even today. Many of the passages are here translated into English for the first time, including the whole of the summary of Peripatetic ethics attributed to 'Arius Didymus'.

Medieval commentary writing has often been described as a way of "doing philosophy," and not without reason. The various commentaries on Aristotle's Categories we have from this period did not simply elaborate a dialectical exercise for training students; rather, they provided their authors with an unparalleled opportunity to work through crucial philosophical problems, many of which remain with us today. As such, this unique commentary tradition is important not only in its own right, but also to the history and development of philosophy as a whole. The contributors to this volume take a fresh look at it, examining a wide range of medieval commentators, from Simplicius to John Wyclif, and discussing such issues as the compatibility of Platonism with Aristotelianism; the influence of Avicenna; the relationship between grammar, logic, and metaphysics; the number of the categories; the status of the categories as a science realism vs. nominalism; and the relationship between categories.
