In a highly conscious break with what is termed "orthodox Darwinism," i.e., evolution by natural selection of individual adaptive character, the author presents his forceful and suggestive attempt to recast evolutionary theory by taking Darwin's later concept of the reproductive mode of genetic groups as fundamental. The goal of this reorientation is a "descriptive behavioral science" of evolution from the most primitive clusters of inorganic matter to human societies. The book is "Blakean" in its scope and tone of vision, but (...) suffers from heaviness of style and its misplaced messianic pretensions and prophetic wrath. However, in arguing for a continuity of cosmological, natural and human evolution, and in suggesting a synthesis of the insights of Darwin and Freud, the book is powerful and convincing.—T. R. H.
