In the great libraries of Europe and the United States, hidden in fading manuscripts on forgotten shelves, lie the works of medieval Hebrew logic. From the end of the twelfth century through the Renaissance, Jews wrote and translated commentaries and original compositions in Aristotelian logic. One can say without exaggeration that wherever Jews studied philosophy - Spain, France, Northern Africa, Germany, Palestine - they began their studies with logic. Yet with few exceptions, the manuscripts that were catalogued in the last century have failed to arouse the interest of modem scholars. While the history of logic is now an established sub-discipline of the history of philosophy, the history of Hebrew logic is only in its infancy. The present work contains a translation and commentary of what is arguably the greatest work of Hebrew logic, the Sefer ha-Heqqesh ha-Yashar of Levi ben Gershom. Gersonides is well known today as a philosopher, astronomer, mathematician, and biblical exegete. But in the Middle Ages he was also famous for his prowess as a logician. The Correct Syllogism is his attempt to construct a theory of the syllogism that is free of what he considers to be the 'mistakes' of Aristotle, as interpreted by the Moslem commentator A verroes. It is an absorbing, challenging work, first written by Gersonides when he was merely thirty-one years old, then significantly revised by him. The translation presented here is of the revised version.

Moses Maimonides was arguably the single most important Jewish thinker of the Middle Ages, with an impact on the later Jewish tradition that was unparalleled by any of his contemporaries. In this volume of new essays, world-leading scholars address themes relevant to his philosophical outlook, including his relationship with his Islamicate surroundings and the impact of his work on subsequent Jewish and Christian writings, as well as his reception in twentieth-century scholarship. The essays also address the nature and aim of Maimonides' philosophical writing, including its connection with biblical exegesis, and the philosophical and theological arguments that are central to his work, such as revelation, ritual, divine providence, and teleology. Wide-ranging and fully up-to-date, the volume will be highly valuable for those interested in Jewish history and thought, medieval philosophy, and religious studies.

In various writings Maimonides claims that God’s knowledge encompasses sublunar things, including human affairs, that we are incapable of understanding the nature of this knowledge, and that the term “knowing” is equivocal when said of God and of humans. In the fourteenth century these claims were given widely divergent interpretations. According to Levi ben Gershom (Gersonides, 1288–1344), Maimonides was compelled by religious considerations to maintain that God knows sublunar particulars in all their particularity, and to adopt a position that was diametrically opposed to the Aristotelian one. By contrast, Moses of Narbonne (Narboni, d.1362) found Maimonides’ views on divine knowledge to be identical with those of the “ancient philosophers,” that is to say, the Peripatetics, as presented by Averroes. Whether ultimately convincing or not, Narboni’s Averroist interpretation forces the reader to admit that Maimonides shares a great deal more in common with Averroes on this topic than is often thought. By examining briefly the view of Maimonides and Averroes on these matters I hope to make Narboni’s interpretation appear less far-fetched.

This thesis investigates for the first time the logical writings of the fourteenth-century philosopher, R. Levi ben Gershom . Gersonides wrote a super-commentary on Averroes' Middle Commentary on the Organon, a commentary on two of Averroes' logical questions, and an independent treatise, The Book of the Correct Syllogism. To say that these writings have been completely neglected would not be quite accurate. Parts of the supercommentary were translated into Latin in the sixteenth century and printed with the works of Aristotle and Averroes; in this format they attracted the attention of Prantl and others. But while the translated works were the most popular of Gersonides' logical writings at that time, they are not the most noteworthy nor the most interesting to modern historians of logic. Hence, it has been necessary to make a review of the writings in manuscript in an attempt to isolate the topics which are likely to be representative and of importance in the development of medieval logic. ;Following an introductory chapter on Gersonides' logical writings, the second chapter deals with Gersonides' conception of logic. Special attention is given to the question of the domain of logic, and specifically, to the claim that logic investigates, in addition to language and thought, real existing things. Chapter three analyzes Gersonides' program of deriving the valid syllogistic moods from rules that yield "consequences on account of the part and the whole" and closes with his defence of the fourth syllogistic figure. ;The next three chapters consider Gersonides' modal logic. Chapter four is devoted to his critique of Aristotle's treatment of modal syllogistic as interpreted by Averroes. It is suggested that some of the criticisms are reminiscent of points made in recent studies of Aristotle's modal logic. In chapters five and six, Gersonides' own modal logic is considered. ;Part two presents a partial edition and translation of Gersonides' Book of the Correct Syllogism. It is argued that Gersonides revised the Correct Syllogism in light of new materials on modal logic which came into his hands after he had written the first edition

ON MAIMONIDES, like other titles in the Wadsworth Philosopher's Series, offers a concise, yet comprehensive, introduction to this philosopher's most important ideas. Presenting the most important insights of well over a hundred seminal philosophers in both the Eastern and Western traditions, the Wadsworth Philosophers Series contains volumes written by scholars noted for their excellence in teaching and for their well-versed comprehension of each featured philosopher's major works and contributions. These titles have proven valuable in a number of ways. Serving as standalone texts when tackling a philosophers' original sources or as helpful resources for focusing philosophy students' engagements with these philosopher's often conceptually daunting works, these titles have also gained extraordinary popularity with a lay readership and quite often serve as "refreshers" for philosophy instructors.

The ArgumentIt is well known that theTractatusof Peter of Spain (later Pope John XXI) was one of the most popular logic textbooks in the Middle Ages and early Renaissance. Less known is theTractatus'sconsiderable reputation and diffusion among the Jews, as evidenced by five translations, two commentaries, and what appears to be anabbreviatio— if not of theTractatusitself, then of a similar work. The present article attempts to understand the phenomenon of theTractatus'spopularity and offers an analysis of the three translations whose authors are known — those by Shemaryah ha-Ikriti (Greece, early to mid-fourteenth century), Abraham Abigdor (late fourteenth century), and Judah b. Samuel Shalom (either Italy or Spain, mid-fifteenth century) — and their subsequent fate. The more popular versions of Abraham Abidgor and Judah Shalom provided Jewish students, many of whom would likely become physicians, with a grounding in logic comparable to that of their Christian counterparts.

The Jewish Philosophy Reader is the first comprehensive anthology of classic writings on Jewish philosophy from the Bible to postmodernism. The Reader is clearly divided into four separate parts: Foundations and First Principles, Medieval and Renaissance Jewish Philosophy, Modern Jewish Thought, and Contemporary Jewish Philosophy. Each part is clearly introduced by the editors. The readings featured are representative writings of each era listed above and are from the following major thinkers: Abrabanel, Baeck, Bergman, Borowitz, Buber, Cohen, Crescas, Fackenheim, Geiger, Gersonides, Goodman, Graetz, Halevi, Hartman, Heschel, Hess, Hirsch, Ibn Ezra, Ibn Gabirol, Ibn Paquda, Kellner, Kook, Krochmal, Leibowitz, Levinas, Maimonides, Maybaum, Mendelssohn, Novak, Philo, Plaskow, Rosenzweig, Saadia, Scholem, Seeskin, Soloveitchik, Spinoza, Strauss, Wolf, Zunz.

This paper introduces the reader to the medieval Hebrew tradition of logic by considering its treatment of Aristotelian syllogistic. Starting in the thirteenth century European Jews translated Arabic and Latin texts into Hebrew and produced commentaries and original compendia.Because they stood culturally and geographically at the cross-roads of two great traditions they were influenced by both.This is clearly seen in the development of syllogistic theory, where the Latin tradition ultimately replaces, though never entirely, its Arabic counterpart.Specific attention is devoted to the debate about the so-called Galenian fourth figure.In medieval Hebrew logic one finds both defenders and detractors of the figure, the former appearing towards the beginning of the period in question.With the ascendancy of scholastic logic the fourth figure virtually disappears from Hebrew texts

Presents five new perspectives on the free will problem, and six interpretations of what Jewish thinkers of the past had to say about the problem. Topics include the concept of freedom that exists independently of a sense of self, arguments against the principle of alternative possibilities, the denial of free will in Hasidic thought, notions of choice held by Medieval Jewish and Islamic thinkers, and Maimonides' concepts of freedom and the sense of shame.

Medieval Jewish intellectuals living in Muslim and Christian lands were strongly concerned to recover what they regarded as a ‘lost’ Jewish philosophical tradition. As part of this project they transmitted and produced many philosophical and scientific works and commentaries, as well as philosophical commentary on scripture, in Judaeo-Arabic and Hebrew, the principal literary languages of medieval Jewry. This volume presents new or revised translations of seven prominent medieval Jewish rationalists: Saadia Gaon, Solomon ibn Gabirol, Moses Maimonides, Isaac Albalag, Moses of Narbonne, Levi Gersonides, Hasdai Crescas and Joseph Albo - including, for the first time in English, the complete Falaquera abridgement of Gabirol's Source of Life. These works range over topics that are both theological (e.g. the creation of the world) and philosophical (e.g. determinism and free choice), but they are characterized by two overarching principles: the unity of truth, and its accessibility to human reason
