This book analyzes major transformations in Jewish life and thought: from idolatry to exclusive monotheism in the biblical age, from state-based identity to cultural nationalism in the Roman empire; and, in the European Diaspora, from theology to secularism and revived political nationalism in the modern period. Fundamental questions are asked about Jewish survival in a variety of topics including prophecy, Jewish law, Midrash, the Roman-Jewish wars, Stoicism, secular poetry in Muslim Spain, Marx and Freud, and Hebrew literature through the ages.
