About Ken Wilber
Kenneth Earl Wilber Jr. is an American writer on transpersonal psychology and his own integral theory, a four-quadrant grid which purports to model all human knowledge and experience. In 1973 Wilber completed his first book, The Spectrum of Consciousness, in which he sought to integrate knowledge from disparate fields. Wilber wrote Sex, Ecology, Spirituality (1995), the first volume of his Kosmos Trilogy, presenting his "theory of everything," a four-quadrant grid in which he summarized his reading in psychology and Eastern and Western philosophy up to that time.
