Recognized as one of the leading philosophers and Jewish thinkers of the twentieth century, Emil Ludwig Fackenheim has been widely praised for his boldness, originality, and profundity. As is well-known, a striking feature of Fackenheim's thought is his unwavering contention that the Holocaust brought about a radical shift in human history, so monumental and unprecedented that nothing can ever be the same again. Fackenheim regarded it as the specific duty of thinkers and scholars to assume responsibility to probe this historical event for its impact on the human future and to make its immense ramifications evident. In Emil Fackenheim's Post-Holocaust Thought and Its Philosophical Sources , scholars consider important figures in the history of philosophy - including Kant, Hegel, Heidegger, and Strauss - and trace how Fackenheim's philosophical confrontations with each of them shaped his overall thought. This collection details which philosophers exercised the greatest influence on Fackenheim and how he diverged from them. Incorporating widely varying approaches, the contributors in the volume wrestle with this challenge historically, politically, and philosophically in order to illuminate the depths of Fackenheim's thought.
