The book is devoted to the thought of one of the 20th century's most interesting philosophers of religion. Heschel, a traditional Polish Jew who became a modern thinker, was also an impressive prophet of interreligious dialogue. The book is the fruit of a scholarly conference held in 2007 at the University of Warsaw, in Heschel's native city, on the occasion of the 100th anniversary of his birth. Given the depth and scope of his thinking, the papers gathered in the volume will be of interest not only to philosophers, theologians, and scholars of Heschel, but also to those who know little about Heschel but are interested in the fundamental problems that appear at the borders between philosophy and theology, religion and modernity, Judaism and Christianity, and, more broadly, problems of interfaith relations and their future. Among the contributors to the volume there are many of the foremost Heschel scholars from the United States and Israel, as well as authors from Poland and other European countries. The authors believe that the infl uence of Heschel will continue to grow worldwide.
