This volume constitutes a series of lectures delivered under the auspices of the and the YWHA, by a member of the faculty of Hebrew Union College. The author his surprise that on one appears, as yet, to have described the reasons why Protestant theology has been so peculiarly existentialist, much less to have this motif in Jewish and Roman Catholic thought. Although existentialism as such has been widely written about, its explicitly religious forms have thus far re as fragments. Rabbi Borowitz undertakes, therefore, to supply an account of religious existentialism for the thoughtful layman. Kierkegaard, Barth, Franz Rosen, Maritain, Berdyaev, Marcel, Reinhold Nisbubr, Bultmann, Buber, Tillich: these are the religious thinkers examined, while a concluding chapter deals with the ""Theatre of the Absurd."" This is a scholarly and urbane book, helpful to all who are looking for a reliable orientation to its subject. The style is lucid and sprightly.
