No Aristotelian doctrine had a greater influence on medieval philosophy and theology than that of the agent, or active, intellect. This influence, however, was mediated by a long tradition of exegesis in which the Greek commentaries of later antiquity played a dominant role. The two commentaries presented here were known to have been influential in the Middle Ages and the Renaissance. The first is a short treatise called the "De intellectu", attributed to Alexander of Aphrodisias; the second a paraphrase of Aristotle's "De anima" (3.4-8) by Themistius, which also includes a major interpretation of "De anima" (3.5), the chapte on the active intellect.

This book brings together twenty articles giving a comprehensive view of the work of the Aristotelian commentators. First published in 1990, the collection is now brought up to date with a new introduction by Richard Sorabji. New generations of scholars will benefit from this reissuing of classic essays, including seminal works by major scholars, and the volume gives a comprehensive background to the work of the project on the Ancient Commentators on Aristotle, which has published over 100 volumes of translations since 1987 and has disseminated these crucial texts to scholars worldwide. The importance of the commentators is partly that they represent the thought and classroom teaching of the Aristotelian and Neoplatonist schools and partly that they provide a panorama of a thousand years of ancient Greek philosophy, revealing many original quotations from lost works. Even more significant is the profound influence – uncovered in some of the chapters of this book – that they exert on later philosophy, Islamic and Western. Not only did they preserve anti-Aristotelian material which helped inspire Medieval and Renaissance science, but they present Aristotle in a form that made him acceptable to the Christian church. It is not Aristotle, but Aristotle transformed and embedded in the philosophy of the commentators that so often lies behind the views of later thinkers.

Maimonideanism, the intellectual culture inspired by Maimonides’ writings, has received much recent attention. Yet a central aspect of Maimonideanism has been overlooked: the formal reception of the Guide of the Perplexed through commentary. In Rewriting Maimonides, Igor H. De Souza offers a comprehensive analysis of six early philosophical commentaries, written in Italy, Spain, and France, by some of Maimonides’ most loyal followers. The early commentaries represent the most creative period of exegesis of the Guide. De Souza’s analysis dispels the notion that the tradition of commentary on the Guide is monolithic. Rather, De Souza’s study illuminates how each commentator offers distinctive readings. Challenging the hierarchy of text and commentary, Rewriting Maimonides studies commentaries on the Guide as texts in their own right. De Souza approaches the form of commentary as a multifaceted cultural practice. Employing historical, philosophical, and literary methods, this publication fills a lacuna in the history of the Guide through a global perspective on commentary.

This volume of original articles covers diverse aspects of ancient philosophy, including the work of Plato, Aristotle, and the stoics.

In late antiquity the works of Plato and Aristotle were subject to intense study, which eventually led to the development of a new literary form, the philosophical commentary. Until recently these commentaries were understood chiefly as sources of information for the masters - Plato and Aristotle - they commented upon. However, in recent years, it has become increasingly acknowledged that the commentators themselves - Aspasius, Alexander, Themistius, Porphyry, Proclus, Philoponus, Simplicius and others - even though they worked in the Platonist - Aristotelian framework, contributed to this tradition in original, innovative and significant ways such that their commentaries are philosophically important sources in their own right. This book provides the first systematic introduction to the 'philosophy' of the commentators: their way of doing philosophy and the kind of philosophical problems they found interesting.Although there was no philosophy of the commentators in the sense of a definite set of doctrines, Tuominen shows how the commentary format was nevertheless a vehicle for original philosophical theorizing and argues convincingly that the commentators should take their place alongside other philosophers of antiquity in the history of western philosophy.
