This stimulating and wide-ranging book mounts a profound enquiry into some of the most pressing questions of our age, by examining the relationship between biological science and Christianity. The history of biological discovery is explored from the point of view of a leading philosopher and ethicist. What effect should modern biological theory and practice have on Christian understanding of ethics? How much of that theory and practice should Christians endorse? To what extent can "nature" set our standards? Professor Clark takes a reasoned look at biological theory since Darwin and argues that an orthodox Christian philosophy is better able to accommodate the truth of such theory than is the sort of progressive, meliorist interpretation of Christian doctrine that is usually offered as the properly "modern" option.
