  The institute for Jewish adult education which opened, under Rosenzweig’s leadership, in the fall of 1920, was called “The New Jewish Lehrhaus,” and its name both linked it to the traditional Jewish house of study, the “Beit Midrash” and, as “new”, distanced itself from traditional study at the same time. The Lehrhaus aimed to implement, even in the form of instruction it adopted, the approach to Jewish return Rosenzweig had formulated. It did so by doing away with the usual distance in the classroom between teacher and students. In the Lehrhaus, most teachers were intentionally not masters of the subject they chose to teach; they did not come to the classroom with answers, but saw themselves, rather, as engaged in a questioning-in-common with their students. The job of the institute and its leader, Rosenzweig asserted, was to ensure the “pedagogical fruitfulness of amhaaratzus [i.e., ignorance].” Here the questions that emerged naturally among thoughtful students who recognized their own ignorance of Jewish sources, served to forge a living and intellectually satisfying path of Jewish enlightenment.
