Maimonides (d. 1204) tolerated no idea that failed the test of reason. An ancient and robust tradition of superstition among the Jews did not deter him. Maimonides either ignored or rationalized scores of Talmudic halachot based on astrology, demonology, and magic.
Maimonides denounced astrology passionately, despite its popularity, calling the belief “stupidity” and its practitioners “fools.” His argument bears emphasis: Maimonides opposed astrology primarily on scientific rather than religious grounds. The Torah prohibits divination from the sky, he ruled, not because it displays a lack of faith in God, but simply because it is false.
