Menahem Mendel Schneerson (1902-1994) was the seventh and seemingly last Rebbe of the Habad-Lubavitch dynasty. Marked by conflicting tendencies, the thinker was a radical messianic visionary who promoted a conservative political agenda, a reclusive contemplative who built a hasidic sect into an international movement, and a man dedicated to the exposition of mysteries who nevertheless harbored many secrets. Schneerson astutely masked views that might be deemed heterodox by the canons of orthodoxy while engineering a fundamentalist ideology that could subvert traditional gender hierarchy, the halakhic distinction between permissible and forbidden, and the social-anthropological division between Jew and Gentile. Elliot R. Wolfson concentrates on Schneerson's apocalyptic sensibility and promotion of a mystical consciousness that undermines all discrimination. Situating Habad thought within the evolution of kabbalistic mysticism, the history of Western philosophy, and Mahayana Buddhism, he articulates Schneerson's rich theology and profound philosophy, concentrating on the nature of apophatic embodiment, semiotic materiality, hypernomian transvaluation, nondifferentiated alterity, and atemporal temporality.
