The essays published in this volume under the title of _Studies in Judaism_ have been written on various occasions and at long intervals. There is thus no necessary connection between them. If some sort of unity may be detected in the book, it can only be between the first three essays—on the Chassidim, Krochmal, and the Gaon—in which there is a certain unity of purpose. The purpose in view was, as may easily be gathered from the essays themselves, to bring under the notice of the English public a type of men produced by the Synagogue of the Eastern Jews. That Synagogue is widely different from ours. Its places of worship have no claims to “beauty of holiness,” being in their outward appearance rather bare and bald, if not repulsive; whilst those who frequent them are a noisy, excitable people, who actually dance on the “Season of Rejoicing” and cry bitterly on the “Days of Mourning.” But among all these vagaries—or perhaps because of them—this Synagogue has had its moments of grace, when enthusiasm wedded to inspiration gave birth to such beautiful souls as Baalshem, such fine sceptics as Krochmal, and such saintly scholars as Elijah Wilna. The Synagogue of the West is certainly of a more presentable character, and free from excesses; though it is not devoid of an enthusiasm of its own which finds its outlet in an ardent and self‐ sacrificing philanthropic activity. But owing to its practical tendency there is too little room in it for that play of intellectual forces which finds its extravagant expression in the saint on the one hand, and the learned heretic on the other. Eight of these essays are more or less of a theological nature. But in reading the proofs I have been struck by the fact that there is assumed in them a certain conception of the Synagogue which, familiar though it be to the Jewish student, may appear obscure and even strange to the general English reader. For brevity’s sake I will call it the High Synagogue, though it does not correspond in all details to what one is accustomed to understand under the term of High Church. The High Synagogue has a history which is not altogether without its points of interest. Some years ago when the waves of the Higher Criticism of the Old Testament reached the shores of this country, and such questions as the heterogeneous composition of the Pentateuch, the comparatively late date of the Levitical Legislation, and the post‐exilic origin of certain Prophecies as well as of the Psalms began to be freely discussed by the press and even in the pulpit, the invidious remark was often made: What will now become of Judaism when its last stronghold, the Law, is being shaken to its very foundations? Such a remark shows a very superficial acquaintance with the nature of an old historical religion like Judaism, and the richness of the resources it has to fall back upon in cases of emergency.
