What would a truly integral culture look like, a culture that included body, mind, soul, and spirit? In this new and groundbreaking book, Ken Wilber uses his widely acknowledged "spectrum of consciousness" model to completely rewrite our approach to such important fields as psychology, spirituality, anthropology, cultural studies, art and literary theory, ecology, feminism, and planetary transformation. What would each of those fields look like if we wholeheartedly accepted the existence of not just body and mind but also soul and spirit? Wilber weaves these various fragments together into a coherent and compelling vision for the modern and postmodern world.
