This is the first in a projected set of three volumes charting recent thought in the title's interrelated areas, the title itself being a slight misnomer since sex and ecology are the foci of the forthcoming volumes. Here, however, Wilber elaborates at great length several contemporary systematic theories concerned with the biological, psychological, spiritual and metaphysical aspects of life and the various evolutionary stages of each. He then offers an overview of spiritual practices that can lead to an evolved "omega point" of consciousness. Wilber, a transpersonal psychologist and the author of No Boundary, among other works, has unfortunately tried too hard to cram everything possible into this massive undertaking. The result is that even the hundreds of pages of notes (sometimes useful, sometimes merely repetitive) become a mass of ideas and names. Wilber is a well-read, sophisticated and energetic thinker; yet his style veers from the discursively expansive to the overly condensed.
