Shaul Magid explores one of the most provocative and radical traditions of Hasidic thought, the school of Izbica and Radzin, that Rabbi Gershon Henokh founded in nineteenth-century Poland. Magid traces the intellectual history of this strand of Judaism into the present. He puts the Hasidism of Izbica-Radzin in context and provides a model for inquiry into other forms of Hasidism.
