The concluding chapter draws on the story of Rosenzweig’s near conversion to Christianity and return to Judaism to explain why, for Kant and his heirs, what is at issue in reason’s conflict with itself is our ability to affirm both the value of the world and of human action in the world. The chapter explains why Rosenzweig came to view the conflict of reason as the manifestation of a more fundamental tension between one’s selfhood and one’s worldliness, which could only be dissolved by understanding human action in the world as the means by which God is both cognized and partly realized. To make Rosenzweig’s ideas more accessible, the chapter compares them with contemporary interpretations of Kant’s views on the nature of practical knowledge and (intentional) action. It also shows how the book’s take on the issues that shaped the contours of post-Kantian German Idealism can help us see that the conflict of reason can be regarded as the underlying concern that recent competing interpretations of this period share.
