Despite the revival of intellectual history in recent years, there is still relatively little research into German-Jewish intellectual history between 1933 and 1938. The present work studies for the first time the important discussions of the period from the debate between Leo Strauss and Julius Guttmann, Alexander Altmann’s contribution to Jewish theology, to the reception of the work of Franz Rosenzweig and Martin Heidegger as well as the works of David Baumgardt and Fritz Heinemann. Many now forgotten texts of those discussions have been made accessible here. All the leading figures presented in this study were sooner or later forced to choose between philosophy and law.
