This is a study of the key features of the moral psychology and metaethics of three important medieval Jewish philosophers, Saadia Gaon, Bahya ibn Pakuda, and Moses Maimonides.

This is a study of the key features of the moral psychology and metaethics of three important medieval Jewish philosophers, Saadia Gaon, Bahya ibn Pakuda, and Moses Maimonides. They are selected because of the depth and subtlety of their thought and because of their relevance to central, enduring issues in moral philosophy. The book examines their views of freedom of the will, the virtues, the rationality of moral requirements, and the relation between rational justification and revelation. Their appropriations of Neoplatonic and Aristotelian thought are explicated, showing how their theistic commitments make crucial differences to moral psychology and moral epistemology. All three thinkers developed rationalistic philosophies and sought to show how Judaism does not include doctrines in conflict with reason. Maimonides receives the fullest attention, given that he articulated the most systematic and influential accounts of the main issues. While explicating the main claims and arguments of these thinkers, the book also shows the respects in which their thought remains relevant to several important issues and debates in moral philosophy. These thinkers' views of ‘the reasons of the commandments’ (in Torah) include resources for a sophisticated moral epistemology of tradition. The points of contact and contrast between medieval Jewish moral thought and the practical wisdom approach to moral theory and also natural law approaches are examined in detail.
