"Kenneth Earl Wilber II (born January 31, 1949) is an American writer on transpersonal psychology and his own integral theory, a four-quadrant grid which suggests the synthesis of all human knowledge and experience.
A provocative examination of how the great religious traditions can remain relevant in modern times by incorporating scientific truths learned about human nature over the last century.
A single purpose lies at the heart of all the great religious traditions: awakening to the astonishing reality of the true nature of ourselves and the universe. At the same time, through centuries of cultural accretion and focus on myth and ritual as ends in themselves, this core insight has become obscured. Here Ken Wilber provides a path for reenvisioning a religion of the future that acknowledges the evolution of humanity in every realm while remaining faithful to that original spiritual vision. For the traditions to attract modern men and women, Wilber asserts, they must incorporate the extraordinary number of scientific truths learned about human nature in just the past hundred years—for example, about the mind and brain, emotions, and the growth of consciousness—that the ancients were simply unaware of and thus were unable to include in their meditative systems. Taking Buddhism as an example, Wilber demonstrates how his comprehensive Integral Approach—which is already being applied to several world religions by some of their adherents—can avert a "cultural disaster of unparalleled proportions": the utter neglect of the glorious upper reaches of human potential by the materialistic postmodern worldview. Moreover, he shows how we can apply this approach to our own spiritual practice. This, his most sweeping work since Sex, Ecology, Spirituality, is a thrilling call for wholeness, inclusiveness, and unity in the religions of tomorrow.
