1135-1204. Jewish rabbi and philosopher, born in Cordoba, Spain. Known as one of the greatest Hebrew scholars, he attempted to reconcile faith and reason. He left Spain in 1160 to escape the persecution of the Jews and settled in Fez, and later in Cairo, where he was personal physician to Sultan Saladin. His codification of Jewish law is known as the Mishneh Torah/The Torah Reviewed 1180; he also formulated the Thirteen Principles, which summarize the basic beliefs of Judaism. His philosophical classic More nevukhim/The Guide to the Perplexed 1176-91, helped to introduce Aristotelian thought into medieval philosophy.
