This is a fantastic book, certain to stimulate many debates, and not just about its subject, Franz Rosenzweig. At the heart of Batnitzky's text is an argument about religious truth and the form it takes in the modern world, about “idolatry” and “representation.” As understood by the author, the law against idolatry did not mean for Rosenzweig what it meant for Maimonides and Hermann Cohen; it does not reflect the epistemological conundra that go into the presentation of a God who outstrips all sensual image and mental representation. Instead, Batnitzky takes idolatry to mean the act of fixing upon one single image, thereby limiting God's freedom to appear in different forms. In this light, the term representation gets pulled away from the German Vorstellung (i.e. with the presentation of an abstract truth) and aligned with the verb vertreten (suggesting how one represents that truth through one's very being, one's own physical existence and image).
