Medieval Jewish philosophy, like Islamic and Christian philosophy, is fundamentally focused on the relationship between “faith and reason.” Arising as an effort toward harmonizing the tenets of Judaism with current philosophic teachings, medieval Jewish philosophy deals with problems in which there appears to be a conflict between philosophical speculation and acceptance of dogmas of the Judaic faith. This chapter reviews the nature of Jewish philosophy as well as the tension between Judaism and Science. It positions Jewish philosophy within the broader context of Western thought, and distinguishes philosophy from the world of the Rabbis. It then provides an overview of the major themes of the work, which include issues of omniscience, providence, reason, and moral theory.
