This book is, quite literally, a ""theology of things"" inasmuch as it is concerned, not with the attitude of the Christian toward the relationships (described by the sciences) between man and the natural world, but with the nature of those particular, human relationships themselves. Professor Bonifazi's quarry is the almost inborn and peculiarly Christian view of the world as an isolated entity of God's creation, distinct from things ""spiritual"" and unspeakably inferior to them, and his thesis is the belief that the Christian leads a truly Christian life--i.e., one in harmony with all of God's creation--when he sees the universe, including the physical universe, as an integrated whole, as one with himself in the divine plan which is Providence. That concept is pursued through the Scriptures, the writings of the philosophers and the scientists, until conrad's thesis is seen as a fully developed, logically sound and intellectually cogent view of the totality of creation which, if it gains the currency which it deserves, may at last make possible a true Christian humanism by allowing for the full development of the Christian personality. This is not a book for the dilettante, but for the serious student and for the philosopher as well as for the theologian. To it applies that overworked description, a ""seminal book.
