The Evolution of Human Consciousness

"Crook has an extensive range of interests and writes with authority on the whole sociobiological spectrum. He discusses the behavior of insects, birds, primates, and so forth, with impressive thoroughness and detail. He ... introduces an equally expert and apparently firsthand discussion of Eastern philosophy, especially Zen Buddhism. His purpose is to emphasize the duality, or perhaps multiplicity, of consciousness, and the importance of society's more objective facets. A scholarly work complete with excellent bibliographies, index, and references." --Choice
