Themistius' treatment of Books 1-3 of Aristotle's Physics presents central features of Aristotle's thought about principles, causation, change and infinity. The tradition of synthesising and epitomising exegesis is here raised to a new level by the innovative method of paraphrase pioneered by Themistius. Taking a selective, but telling, account of the earlier Peripatetic and Presocratic tradition, Themistius creates a framework that can still be profitably used in the study of Aristotle. This volume contains the first English translation of Themistius' commentary, accompanied by a detailed introduction, extensive explanatory notes and a bibliography.

Book 2 of the Physics is arguably the best introduction to Aristotle's work, both because it explains some of his central concepts, such as nature and the four causes, and because it asks some gripping questions that are still debated today: Is chance something real? If so, what? Can nature be explained by chance, necessity and natural selection, or is it purposive? Philoponus' commentary is not only a valuable guide, but also a work of Neoplatonism with its own views on causation, the Providence of Nature, the problem of evil and the immortality of the soul.

Plato in the Third Sophistic examines the influence and impact of Plato and Platonism in the era of Byzantine and Christian rhetoric. The volume brings together specially commissioned articles from leading scholars of late antique philosophy and literature. Their examinations show that Plato is the single most important and influential literary figure used to frame the literature of this time. Plato in the Third Sophistic will help scholars and students from a wide range of disciplines to better understand the development of Christian literature in this era as an essential link in the history of Platonism as well as that of Christianity.

In this volume of 18 essays, leading philosophers address the varied, volatile and novel encounters between contemporary and antique thought. They reconceive and redeploy the problems of ancient metaphysics: one and the many, the potential and the actual, the material and immaterial, the divine and the world itself. Alongside these essays are three original and previously unpublished translations of texts by Gilles Deleuze, Pierre Aubenque and Barbara Cassin.

This book examines scholastic conceptions of final causality through the methods and concerns of historical theology. It argues the history of final causality is most profitably understood according to the interplay of regularity, order, and intentionality as interpretive categories. Within this analytic framework, the author explores the history and theological implications of final causality from Aristotle to Nicole Oresme, utilizing shifts in the dominant interpretive category to clarify how final causality could change from one of four co-equal explanatory strategies in Aristotle to the cause of causes in Avicenna to a merely metaphorical cause in Walter Chatton. Theological debates – ranging from questions of creation, the relationship of primary and secondary causality and of the ultimate good to secondary goods, the autonomy or instrumentality of nature, and the compatibility of chance with providence – motivated many of these changes. The chapters examine final causality in Aristotle and the commentorial tradition from late antiquity to medieval Arabic sources and then consider in detail various scholastic understandings and uses of final causality. The book will be of particular interest to scholars of historical theology, systematic theology, scholastic thought, and medieval philosophy.

Aristotle's Physics Book 3 covers two subjects: the definition of change and the finitude of the universe. Change enters into the very definition of nature as an internal source of change. Change receives two definitions in chapters 1 and 2, as involving the actualisation of the potential or of the changeable. Alexander of Aphrodisias is reported as thinking that the second version is designed to show that Book 3, like Book 5, means to disqualify change in relations from being genuine change. Aristotle's successor Theophrastus, we are told, and Simplicius himself, prefer to admit relational change. Chapter 3 introduces a general causal principle that the activity of the agent causing change is in the patient undergoing change, and that the causing and undergoing are to be counted as only one activity, however different in definition. Simplicius points out that this paves the way for Aristotle's God who moves the heavens, while admitting no motion in himself. It is also the basis of Aristotle's doctrine, central to Neoplatonism, that intellect is one with the objects it contemplates.In defending Aristotle's claim that the universe is spatially finite, Simplicius has to meet Archytas' question, "What happens at the edge?". He replies that, given Aristotle's definition of place, there is nothing, rather than an empty place, beyond the furthest stars, and one cannot stretch one's hand into nothing, nor be prevented by nothing. But why is Aristotle's beginningless universe not temporally infinite? Simplicius answers that the past years no longer exist, so one never has an infinite collection.

Supporting the twelve volumes of translation of Simplicius' great commentary on Aristotle's Physics , published between 1992 and 2021, this volume presents a general introduction to the commentary. It covers the philosophical aims of Simplicius' commentaries on the Physics and the related text On the Heaven ; Simplicius' methods and his use of earlier sources; key themes and comparison with Philoponus' commentary on the same text. In the first chapters of his work, Aristotle raises the question of the number and character of the first principles of nature and feels the need to oppose the challenge of the paradoxical Eleatic philosophers who had denied that there could be more than one unchanging thing. By 1.7, Aristotle reaches the conclusion that we must distinguish one substratum and two contrary states that it may possess: a form and a privation of that form. But this only foreshadows what is to follow. In book 2, Aristotle introduces four kinds of explanatory factor: besides the material substratum of a thing and its form, there is its function or purpose, and the efficient cause of its taking on new forms. He goes on in Books 3 to 8 to discuss causation, chance and necessity, motion, infinity, vacuum, spatial relations and the continuum and he postulates the need for a divine first mover as the source of purposive motion in celestial bodies.
