First published in 1902, The Varieties of Religious Experience initiated the psychological study of religion, paving the way for Freud and Jung as well as for clinical and paranormal branches of psychology. Written with humour and erudition, its theories of conversion, saintliness, ecstasy and mysticism continue to provoke controversy and inquiry. The book remains the best introduction to James's thought, demonstrating his characteristic insistence upon the importance of personal experience and his almost devotional respect for the mysteries of the human mind. Richly illustrated with.
