Bahya Ibn Pakuda was born c. 1050, and lived for some time in Saragossa in Spain. His major work was written in Arabic, but it is most well-known by its Hebrew title Hovot ha-Levavot (Duties of the Heart). It enjoyed enormous popularity and was reprinted many times. In the book Bahya investigates the motivation of Jewish practice and embarks on a philosophical enquiry into the nature of God, religion, and man. He was very much influenced by the Neoplatonism of his age, as well as by the Muslim mystics. This edition by Menahem Mansoor is the first translation of the work from the original Arabic text, and this shows a number of variations from the Hebrew version. He has added an Introduction and Notes which draw attention to the influences on Bahya's thought and to other relevant material. 'The accepted and normative translation . . . reliable and readable. This book belongs in even the smallest collections of Judaica, as well as of ethical literature.' Choice

Enlightening Revolutions_a collection of outstanding essays by highly prominent scholars_examines the different ways in which the relation between politics and philosophy has been understood and enacted over the ages. The volume sheds light on key theoretical and historical issues: the intriguing position and historical influence of medieval Jewish and Islamic rationalism; the advent of modernity in the thought of Machiavelli and Hobbes; the prospects for greatness in modernity as seen by Adam Smith, Jonathan Swift, the Founding Fathers, and Alexis de Tocqueville; and the prospects for philosophic excellence in modern times as seen by, among others, Montesquieu and Leo Strauss, as well as through the eyes of Plato and the Bible. The volume is dedicated to Ralph Lerner, Professor Emeritus at the University of Chicago. It honors Lerner's splendid teaching and scholarship over half a century, and testifies in some measure to his enlightening, enlivening, gracefully witty, and humanizing activity and example.
