Hasdai ben Abraham Crescas (Catalan: [həzˈðaj ˈβeɲ ʒuˈða ˈkɾeskəs]; Hebrew: חסדאי קרשקש; c. 1340 in Barcelona – 1410/11 in Zaragoza) was a Spanish-Jewish philosopher and a renowned halakhist (teacher of Jewish law). Along with Maimonides ("Rambam"), Gersonides ("Ralbag"), and Joseph Albo, he is known as one of the major practitioners of the rationalist approach to Jewish philosophy.
Biography
Hasdai Crescas came from a family of scholars. He was the grandson of the Talmudist Hasdai ben Judah Crescas, and a disciple of the Talmudist and philosopher Nissim of Gerona. Following his teacher's footsteps, he became a Talmudic authority and a philosopher of great originality. He is considered critical in the history of modern thought for his profound influence on Baruch Spinoza.
After leaving Barcelona, he held the administrative position of crown rabbi of Aragon. He seems to have been active as a teacher. Among his fellow students and friends, Isaac ben Sheshet, famous for his responsa, takes precedence.
