The eighth book of Aristotle's Physics is the culmination of his theory of nature. He discusses not just physics, but the origins of the universe and the metaphysical foundations of cosmology and physical science. He moves from the discussion of motion in the cosmos to the identification of a single source and regulating principle of all motion, and so argues for the existence of a first 'unmoved mover'. Daniel Graham offers a clear, accurate new translation of this key text in the history of Western thought, and accompanies the translation with a careful philosophical commentary to guide the reader towards an understanding of the wealth of important and influential arguments and ideas that Aristotle puts forward.

Physics in Neoplatonist thought, the subject which occupies the second volume of this sourcebook, was innovative: the world of space and time was causally ordered by a nonspatial, nontemporal world, and this view required original thinking

The third volume of this invaluable sourcebook covers three main subject areas. First, the metaphysics of Aristotle's logical works: the concepts of universal and particular underwent surprising transformations in this period, which gave rise to debates, still raging today, on personal survival after an interruption such as death. Second, logic in a more conventional sense: perhaps the most impressive debate was on the existence of the subject in singular and universal statements. There was also debate about the very different Aristotelian and Stoic conceptions of syllogism, of modal logic, of induction, of the nature of mathematics, and of philosophy of language. Third, the higher metaphysics of the Neoplatonists taught Augustine, and indirectly Descartes, to look for truth within themselves. The Neoplatonists struggled with the question whether our higher intellectual selves have distinct individuality, and thus they fed both sides in the great medieval debate between Aquinas and the followers of Averroes on individual human immortality. All sources appear in English translation and are carefully linked and cross-referenced by editorial comment and explanation. Bibliographies are provided throughout.

An astounding project of analysis on more than one hundred translations of ancient philosophical texts, this index of words found in the Ancient Commentators on Aristotle series comprises some 114,000 entries. It forms in effect a unique dictionary of philosophical terms from the post-Hellenistic period through to late antiquity and will be an essential reference tool for any scholar working on the meaning of these ancient texts. As traditional dictionaries have usually neglected to include translation examples from philosophical texts of this period, scholars interested in how meanings of words vary across time and author have been ill served. This index fills a huge gap, therefore, in the lexical analysis of ancient Greek and has application well beyond the reading of ancient philosophical commentaries. Bringing together the full indexes from 110 of the volumes published in Bloomsbury's Ancient Commentators on Aristotle series, McKirahan has combined each word entry and analysed how many times particular translations occur. He presents his findings numerically so that each meaning in turn has a note as to the number of times it is used. For meanings that are found between one and four times the volume details are also given so that readers may quickly and easily look up the texts themselves.

This volume brings together, for the first time, experts on Greek, Syriac, and Arabic traditions of doxography, in order to investigate and present shared contexts and questions, and to initiate future collaboration among the fields of classics, Arabic studies, and the history of philosophy.

This book provides a comprehensive and in-depth study of Physics I, the first book of Aristotle's foundational treatise on natural philosophy. While the text has inspired a rich scholarly literature, this is the first volume devoted solely to it to have been published for many years, and it includes a new translation of the Greek text. Book I introduces Aristotle's approach to topics such as matter and form, and discusses the fundamental problems of the study of natural science, examining the theories of previous thinkers including Parmenides. Leading experts provide fresh interpretations of key passages and raise new problems. The volume will appeal to scholars and students of ancient philosophy as well as to specialists working in the fields of philosophy and the history of science.
