The diaries and letters of philosopher Hugo Bergman provide a deep insight into the thought processes of a sensitive and creative thinker. This collection, published for the first time in German, documents the significant upheavals in the Jewish world of the 20th century. Bergman reflects on the renaissance of Judaism, Jewish settlement in Palestine, and the tragic events of the annihilation of European Jewry. Furthermore, he addresses the search for God, encounters with other religions, as well as the moral and political challenges in the context of the State of Israel. These works are not only a personal testament but also a valuable contribution to Jewish history and philosophy.
