Professor Parrinder's classic survey of his own field of study, out of print for several years, has been thoroughly revised and updated and is now issued in paperback for the first time. In it, he considers the meaning and purpose of the study of other religions, especially those of Asia, in view of their increasing presence in our society. He discusses how other religions should be approached, their varying truth claims, and the use of propaganda and missionary work. He demonstrates clearly the vital differences between the world's religions and urges understanding at social and personal levels.
