This book deals with the characteristics of the Messianic idea, surveying its historical appearances and expressions in the philosophies of very different thinkers such as Isaac Abarbanel, Solomon Molcho, the Maharal of Prague, Menasseh ben Israel, Abraham Isaac Kook and Yissachar Shlomo Teichtal. These thinkers all embarked on a mutual search for religious significance of the tragic experience of exile, namely in the new era of the history of the Jews, from the Expulsion of Spain through the Holocaust. They sought to give meaning to the yearning for redemption, which became an essential and urgent question with the atrocities of history.
