»Stern der Erlösung« (1921) by Franz Rosenzweig (1886-1929) is one of the great systematic works of 20th century philosophy. At the same time it is an attempt to create a foundation for Jewish identity with explicit recourse to the Bible and in contradistinction to assimilated Judaism, an attempt that for many interpreters has lost none of its actuality. What are the sources that Rosenzweig draws upon for inspiration? Which philosophers and theologians does he enter into an - explicit or implicit - dialogue with? How does he transform those sources and relate them to his arguments? The 24 articles in this collection discuss selected passages of »Stern der Erlösung« in quest of answers to these questions. The results cast a new, and frequently surprising, light on Rosenzweig's thinking.
