This is the first reference ever devoted to medieval philosophy. It covers all areas of the field from 500-1500 including philosophers, philosophies, key terms and concepts. It also provides analyses of particular theories plus cultural and social contexts.

Abū’l-Barakāt is a renowned philosopher of the Arabic-Jewish milieu who composed in his magnum opus the Kitāb al-Mu‘tabar, a comprehensive metaphysics which challenged the accepted notions of the traditional metaphysical philosophy. ‘Abū’l-Barakāt al-Baghdādī’s Metaphysical Philosophy’ examines the novel philosophical conceptions of the first book of the Metaphysics of the Kitāb al-Mu‘tabar. The aim is to present a developed conception of Abū’l-Barakāt’s systematic metaphysics. This is accomplished by following the order of topics discussed, while translating the relevant passages. These different topics comprise stages of cognition that move from an analysis of time, creation and causality to the conception of a higher spiritual realm of mental entities and a conception of God as the First Knower and Teacher. The epistemological and ontological conceptions are analyzed at each culminating stage. ‘Abū’l-Barakāt al-Baghdādī’s Metaphysical Philosophy’ analyzes vast portions of the metaphysical study for the first time. The book will thus be a valuable resource for all those seeking an original and broad metaphysics, and for students and scholars of Jewish and Islamic Philosophy. Furthermore, it is of importance for those seeking a metaphysics related to scientific theories and those interested in the history of science and metaphysics.

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.

Although Aristotle was not the first to understand objects in terms of their matter and their form, the account he developed has exercised a major influence on Western philosophy to this day. The History of Hylomorphism: From Aristotle to Descartes collects sixteen essays by experts that consider aspects of the first two thousand years of the history of hylomorphism, starting with Aristotle's immediate successors and ending with Descartes. It includes discussions of Hellenistic, Roman, Arabic, medieval, and early modern philosophers, examining the ways in which Aristotle's central ideas and concepts were progressively modified by these thinkers. Hylomorphism, as we understand it today, owes much to the way in which it was interpreted, and re-interpreted, during this period. Through a study of their work we can see how questions in contemporary metaphysics and philosophy of mind, such as Descartes's mind-body problem, came to be formulated.

Plato's doctrine of the soul, its immaterial nature, its parts or faculties, and its fate after death (and before birth) came to have an enormous influence on the great religious traditions that sprang up in late antiquity, beginning with Judaism (in the person of Philo of Alexandria), and continuing with Christianity, from St. Paul on through the Alexandrian and Cappadocian Fathers to Byzantium, and finally with Islamic thinkers from Al-kindi on. This volume, while not aspiring to completeness, attempts to provide insights into how members of each of these traditions adapted Platonist doctrines to their own particular needs, with varying degrees of creativity.

Surveys the writings of leading Jewish thinkers, attempting to place them in an historical context and describe their contributions to the history of Jewish medieval thought in simple and lucid terms.
