The vision of reality of our time is derived from science, and with respect to man, derived particularly from the idea of evolution. The author proposes to set forth an understanding of evolution that does justice both to scientific and to biblical experience, and allows belief in a God Who is literally the creator and sustainer of an evolving world. The main instrument for creating such an interpretation, he believes, can be found in the philosophy of A. E. Whitehead. The book offers a brief but widely informed survey of current scientific views on evolution, particularly with respect to the question where purpose is inherent in nature. The discussion of the Whiteheadian outlook includes a comparison between the thought of Whitehead and of Teilhard de Chardin. Well grounded, lucid, and orderly, this book should be of strong appeal to ministers, students, and serious readers concerned with what is still a crucial question in contemporary Christian--and scientific--thought.
