Gersonides’ Afterlife is the first full-scale treatment of the reception of one of the greatest scientific minds of medieval Judaism: Gersonides (1288–1344). An outstanding representative of the Hebrew Jewish culture that then flourished in southern France, Gersonides wrote on mathematics, logic, astronomy, astrology, physical science, metaphysics and theology, and commented on almost the entire bible. His strong-minded attempt to integrate these different areas of study into a unitary system of thought was deeply rooted in the Aristotelian tradition and yet innovative in many respects, and thus elicited diverse and often impassionate reactions. For the first time, the twenty-one papers collected here describe Gersonides’ impact in all fields of his activity and the reactions from his contemporaries up to present-day religious Zionism.

The philosopher, astronomer, and biblical exegete known both as Gersonides and Ralbag (1288-1344) wrote a veritable library of works that testify not only to the breadth of his intellectual concerns but to his attempt to forge a synthesis between the secular sciences and Judaism. This is the first English-language study to assess his place and significance for Jewish thought, and it offers a comprehensive picture of his philosophy that is both descriptive and evaluative.

Gersonides was a highly original Jewish philosopher, scientist and biblical exegete, active in Provence in the first half of the fourteenth century. Ruth Glasner explores his impressive achievements, and argues that the key to understanding his originality is his perspective as an applied mathematical scientist. It was this perspective that led him to examine Aristotelianism from directions different from those usually adopted by contemporary scholastic scholars. Gersonides started on his way, as he himself claims, as a 'mathematician, natural scientist, and philosopher', who believed in his power to solve the main problems of medieval science. He ended up concentrating on his work as a mathematical astronomer, developing techniques of observation and computation, and somewhat less optimistic about the prospect of scientific knowledge.

This is a careful examination of the doctrine of Jewish chosenness in the light of Gersonides's thought on providential suffering and on inherited providence. Gersonides is one of the most interesting and important philosophers of the later Jewish Middle Ages.

The topic of this book is 'creation'. It breaks down into discussions of two distinct, but interrelated, questions: what does the universe look like, and what is its origin? The opinions about creation considered by Norbert Samuelson come from the Hebrew scriptures, Greek philosophy, Jewish philosophy and contemporary physics. His perspective is Jewish, liberal and philosophical. It is 'Jewish' because the foundation of the discussion is biblical texts interpreted in the light of traditional rabbinic texts. It is 'philosophical' because the subject matter is important in both past and present philosophical texts, and to Jewish philosophy in particular. Finally, it is 'liberal' because the authorities consulted include heterodox as well as orthodox Jewish sources. The ensuing discussion leads to original conclusions about a diversity of topics, including the limits of human reason and religious faith, and the relevance of scientific models to religious doctrine.

This book argues that Levi Gersonides articulates a unique model of virtue ethics among medieval Jewish thinkers. Gersonides is recognized by scholars as one of the most innovative Jewish philosophers of the medieval period. His first model of virtue is a response to the seemingly capricious forces of luck through training in endeavor, diligence, and cunning aimed at physical self-preservation. His second model of virtue is altruistic in nature. It is based on the human imitation of God as creator of the laws of the universe for no self-interested benefit, leading humans to imitate God through the virtues of loving-kindness, grace, and beneficence. Both these models are amplified through the institutions of the kingship and the priesthood, which serve to actualize physical preservation and beneficence on a larger scale, amounting to recognition of the political necessity for a division of powers.
