Book excerpt: Controversy is the main instrument by which Judaism develops and shapes its philosophy, theology and law. The rabbinical literature speaks with many voices, debating virtually every subject, and failing to reach a consensus on many. However, this willingness to condone controversy is accompanied by much deliberation. Controversy, and its legal, philosophical and social ramifications, was and remains of unparalleled concern to the rabbis. Today, we are also witness to a burgeoning academic interest in controversy and pluralism in Jewish law. This book is an anthology of passages from the rabbinical literature that address the phenomenon of controversy in Jewish law, affording the English-speaking reader the opportunity for a first-hand encounter with this fascinating material. An extensive analytical introduction contextualizes the material from a philosophical perspective. For more information, please visit www.controversy-dialogue.org.
