"Hasidism on the Margin" explores one of the most provocative and radical traditions of Hasidic thought, the school of Izbica and Radzin that Rabbi Gershon Henokh originated in nineteenth-century Poland. Shaul Magid traces the intellectual history of this strand of Judaism from medieval Jewish philosophy through centuries of Kabbalistic texts to the nineteenth century and into the present. He contextualizes the Hasidism of Izbica-Radzin in the larger philosophy and history of religions and provides a model for inquiry into other forms of Hasidism.
