Emden's Kabbalist contemporary the Vilna Gaon (1720–1797) early modern Rabbinic sage, held the Zohar and Luria in deep reverence, critically emending classic Judaic texts from historically accumulated errors by his acute acumen and scholarly belief in the perfect unity of Kabbalah revelation and Rabbinic Judaism. Though a Lurianic Kabbalist, his commentaries sometimes chose Zoharic interpretation over Luria when he felt the matter lent itself to a more exoteric view. Although proficient in mathematics and sciences and recommending their necessity for understanding Talmud, he had no use for canonical medieval Jewish philosophy, declaring that Maimonides had been "misled by the accursed philosophy" in denying belief in the external occult matters of demons, incantations and amulets.
