From ancient lost tribes to modern campus life, contemporary Jewish scholarship grapples with fundamental questions of identity, rationality, and religious authenticity. A diverse collection of book reviews examines works that span the historical, philosophical, and practical dimensions of Judaism. Hillel Halkin's "Across the Sabbath River" weaves adventure with scholarly investigation in its search for lost Israeli tribes, while Todd Endelman's "The Jews of Britain 1656 to 2000" challenges traditional Anglo-Jewish historiography by incorporating marginalized voices and questioning triumphalist narratives. Kenneth Seeskin's "Judaism and Rationalism" traces autonomy's role in Jewish thought from Genesis onward, mounting a defense of rational Judaism against modern anti-rationalist currents. Additional reviews evaluate works on Jewish prayer, spirituality, religious education, campus life, and prophetic activism. Through methodologies ranging from historical research and philosophical analysis to ethnographic study and textual interpretation, these works illuminate persistent tensions between tradition and modernity, particularity and universalism, and rational versus experiential approaches to Judaism. The collection reflects the interdisciplinary nature of modern Jewish studies while demonstrating the field's remarkable scope and vitality.
