"Ken Wilber is a national treasure. No one is working at the integration of Eastern and Western wisdom literature with such depth or breadth of mind and heart as he." ?ROBERT KEGAN, Professor of Education, Harvard University Graduate School of Education, and author of In Over Our Heads "In ages to come, historians may well view Wilber's work as the pivotal insight that legitimized the return of consciousness and spirit to our age. For this exciting page-turner, psychology owes him a millennial debt." ?T. GEORGE HARRIS, founding editor, Psychology Today and American Health "In a single publication Wilber strides over the entire history of psychology to create new and comprehensive strategies for human survival in the next millennium." ?DON BECK, coauthor of Spiral Dynamics "Integral Psychology is so all-encompassing, lucid, and well written that Ken Wilber deserves the recognition of having single-mindedly brought conceptual order to psychology of the East and West." ?SUSANNE COOK-GREUTER, coeditor of Transcendence and Mature Thought in Adulthood The goal of an "integral psychology" is to honor and embrace every legitimate aspect of human consciousness.This book presents one of the first truly integrative models of consciousness, psychology, and therapy. Drawing on hundreds of sources?East and West, ancient and modern?Wilber creates a psychological model that includes waves of development, streams of development, states of consciousness, and the self, and follows the course of each from subconscious to self-conscious to superconscious. Integral Psychology is Wilber's most ambitious psychological work to date, and it is already being called a landmark study in human development. Ken Wilber is one of the most widely read and influential American philosophers of our time, credited with creating a genuine world philosophy. The eight volumes of his recently published Collected Works include seventeen of his books as well as other writings.
