Hailed as "one of the most significant books ever published," this work of far-reaching vision is a comprehensive exploration of the evolution of human consciousness

In this tour de force of scholarship and vision, Ken Wilber traces the course of evolution from matter to life to mind and describes the common patterns that evolution takes in all three of these domains. From the emergence of mind, he traces the evolution of human consciousness through its major stages of growth and development.

Wilber particularly focuses on modernity and postmodernity: what they mean; how they impact gender issues, psychotherapy, ecological concerns, and various liberation movements; and how the modern and postmodern world conceive of Spirit. This second edition features forty pages of new material, new diagrams, and extensively revised notes.
