This tour de force of scholarship and vision traces the course of evolution from matter to life to mind, describing the patterns it takes in all three domains. Wilber focuses particularly on modernity and postmodernity and how they relate to gender issues, psychotherapy, ecological concerns and liberation movements, and how the world of today can believably conceive of Spirit. This revised edition contains new diagrams, a new preface, and Wilber's reply to his critics. Now in paper.
