The author, who is professor of social philosophy at the Hebrew University in Jerusalem, has made a life-long study of Hasidism, the Jewish revival movement which spread through eastern Europe in the 18th Century. This is a sequel to an earlier volume in which Professor Buber dealt with the early masters of Hasidism. In a lengthy introduction the author introduces us to the central personalities and describes the development of the movement. In the body of the book are to be found tales and sayings attributed to the leaders of the movement. The result is an unusual form of literature, composed of proverbs, short stories, parables, Biblical interpretation and sermonettes. The author has rendered a real service in opening up this literature to readers of English, for, although this is a book which will be of primary interest to students of Jewish religious history, it will no doubt have an appeal to a wider public.
