Thinking in Translation posits the Hebrew Bible as the fulcrum of the thought of Franz Rosenzweig (1886-1929), underpinning a unique synthesis between systematic thinking and biblical interpretation. Addressing a lacuna in Rosenzweig scholarship, the book offers a critical evaluation of his engagement with the Bible through a comparative study of The Star of Redemption and his Bible translation with Martin Buber. The book opens with Rosenzweig’s rejection of German Idealism and fascination with the sources of Judaism. It then analyzes the unique hermeneutic approach he developed to philosophy and scripture as a symbiosis of critique and cross-fertilization, facilitated by translation. An analysis of the Star exposes Rosenzweig’s employment of translation in grafting biblical verses unto the philosophical discussion. It is followed by a reading that demonstrates how his Bible translation reflects an attempt to re-valorize the Tanakh as a distinctively Jewish scripture, over and against Christian appropriations. Thinking in Translation recasts Rosenzweig’s life’s work as a project of melding Judaism and modernity in an attempt to secure their spiritual and intellectual survival.
