A work which like the present aims to present the Jew in every important phase of life, which describes the social, political, economic, and intellectual aspects of Jewish life, as well as the religious, deserves commendation because of its mere scope and completeness. But Mr. Cohen has gone further. He has not fallen into the error of many of the spokesmen for the cultural or historical unity of Jewry of denying or even minimizing the potency of religion as a factor in Jewish survival. Indeed, he everywhere recognizes that the primary or motor force in the organization of the Jewish community, which is the concrete expression of Jewish solidarity, is religious, springing from the desire for public worship. But while religion is the underlying factor, it is not the only factor. There is a sane coordination of the leading aspects of Jewish life, a clear grasp of the relationship between them. Finally, the work is significant because it seeks to represent the Jew in all lands, to paint Jewish life in all its diversity. Mr. Cohen, an Englishman intimately acquainted with conditions in his own country, travelled extensively on the continent in preparation for his task. But his knowledge of American conditions was derived from study of American books and newspapers, and from correspondence, instead of from personal experience. This accounts for such minor lapses, with regard to American conditions, as the statement that the Jews are "excluded from . . . the principal hotels on the east coast of the United States" and hence "take their holiday in the well-known resorts of central and southern Europe" (p. 110). On the whole, however, the attempt to describe Jewish life in all its diversity, as it is lived by Jews in all lands, is crowned with marked success, and the author has ample justification for his claim that he has brought "within the covers of a single book the fullest description yet attempted of all the main aspects and problems of Jewish life in the present day." _The Various Aspects of Jewish Life_
