At the threshold of the 21st century, many people are encountering a spiritual dilemma, where neither secularism nor religion seem adequate. The Psychology of Mature Spirituality addresses this dilemma. Its three sections - integrity, wisdom, and transcendence - describe and analyze a mature form of spirituality that will be a hallmark of future years. Distinguished contributors develop these three themes, showing the reader how human development over the lifespan can lead to a belief system that places neither god(s) nor humankind at the metaphorical centre of the universe. What they describe is a new skeptical spirituality. Combining developmental psychology, depth psychology, and religious studies, this work is an accessible volume which should appeal not only to those involved in psychology, psychoanalysis and religious studies, but also to the interested general reader.
