Professor Cobb presents this study as an inquiry into the distinctiveness of Christianity and into its claim to finality. His argument amplifies some aspects of his earlier, Christian Natural Theology, and reflects his strong adherence to Whitehead's process theology. The line of the argument unfolds along an evolutionary strand. The structure of existence for man is seen as changing through different periods of human history, from the rise of man as a new species through the appearance of civilization and Jaspers' ""axial period"" (800-200 B.C.) during which most of the basic forces of human culture today were released. Structure of experience is interpreted to include man's form of selfconsciousness, the pattern of his social interaction, and the interpretations he makes of the human situation. This book will be found stimulating for its concise and rapid survey of the central core of human advancement, and for the new basis this account provides for considering the relation of Christianity to other world religions.
