A biochemist by profession, a polymath by inclination and erudition, Yeshayahu Leibowitz has been, since the early 1940s, one of the most incisive and controversial critics of Israeli culture and politics. His direct involvement, compelling polemics, and trenchant criticism have established his steadfast significance for contemporary Israeli―and Jewish―intellectual life. These hard-hitting essays, his first to be published in English, cover the ground Leibowitz has marked out over time with moral rigor and political insight. He considers the essence and character of historical Judaism, the problems of contemporary Judaism and Jewishness, the relationship of Judaism to Christianity, the questions of statehood, religion, and politics in Israel, and the role of women. Together these essays constitute a comprehensive critique of Israeli society and politics and a probing diagnosis of the malaise that afflicts contemporary Jewish culture.
