The constitutive distinction of medieval Jewish theology, that between philosophy and Kabbalah, first stabilizes in Nahmanides' work. In his Addenda to Maimonides' Book of Mitzvoth, in his 'Torat ha-Adam', and in his Commentary to the Torah, as in other works, Nahmanides arises to the challenge of the spirit of a philosophical religion. The goal of this seminar is to analyze the way Nahmanides forges this impressive religious alternative to Maimonides' while deeply internalizing its modes of thought. The seminar will approach this task by closely reading the way the distinction between secret and revealed, the inner and the outer are created and articulated.
