Abraham Joshua Heschel was one of the major Jewish thinkers of the twentieth century. The secret of his fascinating personality is in the compelling combination he presents between philosophy, mysticism and social action. In the spirit of Hassidic thinking, Heschel believes that God dwells where man allows Him to enter. He considers man as God’s partner; the prophets in their fight for justice should be a model for modern men. This book is the first comprehensive and in-depth monograph on Abraham Joshua Heschel written in Hebrew.
