Thorough and meticulously researched, this study is based on a comprehensive reading of philosophical arguments drawn from all the major Jewish sources, published and unpublished, from the Geonic period in the ninth century until the dawn of the Haskalah in the late eighteenth century.
The core of the book is a detailed discussion of the four doctrines of Christianity whose rationality Jews thought they could definitively refute: trinity, incarnation, transubstantiation, and virgin birth. In each case, Daniel Lasker presents a succinct history of the Christian doctrine and then proceeds to a careful examination of the Jewish efforts to demonstrate its impossibility. The main text is clearly written in a non-technical manner, with the Christian doctrines and the Jewish responses both carefully explained; the notes include long quotations, in Hebrew and Arabic as well as in English, from sources that are not readily available in English.
At the time of its original publication in 1977 this book was regarded as a major contribution to a relatively neglected area of medieval Jewish intellectual history; the new, wide-ranging introduction prepared for this paperback edition, which surveys and summarizes subsequent scholarship, re-establishes its position as a major work.
'Has acquired the status of a classic. A great deal of new work has been published, however, in the past thirty years. The book is now reprinted by the Littman Library, with a new introduction by the author summarizing these more recent contributions to the subject, which include critical editions of classic texts as well as specialized studies and overviews ... A substantial new bibliography completes the introduction. Thanks are due to the Littman Library for placing this important book before a new generation of readers.'
Nicholas de Lange, Journal of Jewish Studies
'A valuable contribution to this field of research because of its very precise, detailed, and competent study of the themes involved in the disputation and the polemics.'
