 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.Views of Kabbalists regarding Jewish philosophy varied from those who appreciated Maimonidean and other classic medieval philosophical works, integrating them with Kabbalah and seeing profound human philosophical and Divine kabbalistic wisdoms as compatible, to those who polemicised against religious philosophy during times when it became overly rationalist and dogmatic.
