A definitive, international guide to the thought of the most important twentieth-century Jewish philosopher.   In his 1923 essay, I and Thou, the philosopher, theologian, and activist Martin Buber introduced a philosophy of dialogue that achieved a global, interdisciplinary resonance. For Buber, dialogue was more than a conversation; dialogue discloses something essential about our orientation and our lives with one another. This companion assembles twenty-six scholars from a dozen countries to explore Buber’s international reputation and legacy in education, interfaith relations, Judaism, philosophy, politics, and psychology. The result is an essential guide to one of the most influential Jewish thinkers of the twentieth century.
