In a tour de force of scholarship and vision, Ken Wilber traces the course of evolution from matter to life to mind. In each case evolution has a "direction," a tendency to produce more highly organized patterns. The "spirit of evolution" lies in its directionality: order out of chaos. After arriving at the emergence of mind, Wilber traces the evolution of human consciousness through its major stages of development, pointing out that at each stage there is the "dialectic of progress"-every increase in consciousness is bought at a price: new freedom also means new license to choose destruction. He particularly focuses on the rise of modernity and post-modernity-what they mean, how they relate to gender issues, to psychotherapy, to ecological concerns, and to various liberation movements. Most important, he asks: Can spiritual concerns be integrated with massive developments of the modern world?
