"Past and Future Religions" is an essay devoted to the evolution of religious feeling, from classical psychological interpretations to new forms of contemporary spirituality. The book explores the thought of authors such as Freud, Adler, Jung, James, Allport and Maslow, analyzing religion as a human need for meaning, protection, identity, belonging and transcendence. Considerable attention is also given to new religious movements, New Age thought, meditation, natural therapies, spiritual ufology, UFO religions and contactee experiences, offering the reader a journey through psychology, culture, spirituality and the imagery of the future. The work does not aim to establish which faith is true or false, but rather to understand the profound role that religious beliefs have played - and continue to play - in the inner, social and symbolic life of human beings.
