The Philosophy of the Commentators, 200-600 AD, A Sourcebook: Logic and Metaphysics / Edition 1

by Richard Sorabji

Overview

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.
