"Liturgical Reasoning represents a new sub-discipline of Jewish philosophy. Steven Kepnes re-reads the practices of Jewish prayer as sources of instruction in how to reason Jewishly. And he re-reads the great modern Jewish philosophers - Mendelssohn, Cohen, and Rosenzweig - as sources of instruction in how to read prayer philosophically. The result is extraordinary: a systematic theology of modern Judaism and, with it, a unifying vision for modern and contemporary Judaism. Liturgical Reasoning is a required reading for all scholars and students of modern Jewish thought. A stunning achievement." --Peter W. Ochs is Edgar Bronfman Professor of Modern Jewish Thought at the University of Virginia
