But the Hebrew Gazzali was no more successful than his Arabian prototype; and his attacks, although they certainly helped to discredit the Kalam—for which no one cared any longer—were altogether powerless against Peripatetic philosophy, which soon found numerous defenders. In fact, soon after the "Cuzari" made its appearance, Abraham ibn Daud published his "Emunah Ramah" (The Sublime Faith), wherein he recapitulated the teachings of the Peripatetics, Al-Farabi and Ibn Sina, upon the physics and metaphysics of Aristotle, and sought to demonstrate that these theories were in perfect harmony with the doctrines of Judaism. "It is an error generally current," says Ibn Daud in the preface of his book, "that the study of speculative philosophy is dangerous to religion. True philosophy not only does not harm religion, it confirms and strengthens it."
