The Christian world view, contends the author, both needs and embodies a thoroughgoing, rational apologetic as a manifestation of its relevance to the contemporary mind. . . . Christian faith should be defended in terms of criteria which center in rational objectivity as the norm of truth and evaluation. The author, who stands in the tradition of Aquinas, Butler, Orr, and Tennant, deals first with the problem of epistemological approach (part 1). Then he tackles the apologetic of natural revelation, first setting forth the inadequacy of every major alternate to rational empiricism (part 2), then demonstrating the existence of the God of theism (part 3). Each chapter is well outlined, and these outlines appear together in an Analytical Table of Contents. This feature, as well as a bibliography and index, makes this a useful textbook for courses in apologetics and philosophy.
