A very thoughtful and scholarly examination of the state of religion in the world is given us in this volume. Starting with the thesis that in the present world crisis a constructively unifying influence on the part of the forces of religion is desperately needed, the author points out that, as a matter of fact, the religions of the world, though faced by enemies that would destroy them all, are also in conflict among themselves. This thesis is carefully documented by an exhaustive study of Christianity and Islam as representative of the religions of the West, and of Buddhism and Hinduism as representative of the religions of the East. Each of these religions is found to be in fundamental conflict with the secular forces of its environment, to be engaged in struggles within its own fold and to be suspicious and hostile toward other religions. The author's plea is for cooperation without compromise between the religions. He concludes: ""The leading religions of the world are confronted today by a choice of cooperation in the spirit of freedom and of continued conflict in an atmosphere of suspicion and feer. The future of religion and the world depends upon the choice they will make"". A volume which should be of great interest to students of comparative religion and those concerned about the place of religion in the world of today- and of tomorrow.
