Master Class on the Philosophy of Hasdai Crescas
Apr 30 – May 4 all-day

In this class we shall read together texts from The Light of the Lord (Hebrew: Or Adonai), the anti-Aristotelian book by the famed Catalan Jewish philosopher, Rabbi Hasdai Crescas (c. 1340-1410/11). The Light was completed in Saragossa in 1410 and first printed in Ferrara in 1555.

Topics discussed will include space, time, the vacuum, infinity, many worlds, determinism and choice, and the knowledge and love of God. Attention will be given to Crescas’ relation to earlier medieval philosophers, such as Maimonides, Averroes, and Gersonides, and to later medieval and modern philosophers, including Spinoza. Crescas’ theories will also be analyzed with regard to other representatives of the revolutionary “new physics” in 14th-century Europe, particularly Nicole Oresme.

Tuesday, May 1: Infinite Space and Time
Wednesday, May 2: Proofs of God (including Spinoza’s Discussion of Crescas’ short proof)
Thursday, May 3: Choice and Determinism
