  During the following year, Rosenzweig rededicated himself to Judaism by enrolling in courses at the Berlin “Hochschule für die Wissenschaft des Judentums.” Hermann Cohen, the esteemed neo-Kantian, had retired from his professorship in Marburg the year before and was teaching at the Hochschule, and Rosenzweig developed an especially close relationship with the elder philosopher. Rosenzweig formulated his earliest ideas on Jewish education through a public correspondence with Cohen, and it was in the wake of that exchange that Cohen worked together with Rosenzweig and his father—in the months before both Cohen and Rosenzweig’s father died—to establish a new “Academy for the Study of Judaism” meant to advance both scholarship in the field of Jewish Studies and a new program for Jewish communal education. In the month before his death, furthermore, Cohen allowed Rosenzweig to read the proofs to his last great work, Religion of Reason out of the Sources of Judaism, published after his death, in 1919. Rosenzweig found in this work what he took to be a significant break away from Cohen’s critical Idealism, and from the Idealist tradition in general. Moreover, in the book’s presentation of God and the human being as “correlated,” as independent but at once reciprocally determining one another, Rosenzweig believed to discover an anticipation of his own developing view of actuality as grounded in the reciprocal relations between God, self, and world.
