Abstract
This book's purpose is the exposition of the inability of natural science to disprove the existence of God. Clark argues that the acceptance of a mechanistic world view based on Newtonian science makes, unjustifiably, a philosophy of science in which science forgets the many idealizations built into its laws' mathematical formulations. The philosophy of science Mr. Clark espouses is Percy Bridgman's operationalism, i.e., the reduction of the meaning of a concept to the operations used to measure it. The separation of the physical world from what the scientist says about it leads Clark to deny that science is cognitive. It is, rather, a way of increasing nature's utility. As such, it may not be used to support any ethical position whatever.—J. M. B.
