The first half of this book concludes that, if human reason is master, there seems to be no way of equating a good and powerful God with evil in the world. In the second half, searching for a solution, the author takes as his starting point St Augustine's credo, "I believe in order that I may understand". He builds up a series of statements which express the central Christian convictions in relation to the problem of evil, a viewpoint which the reader may accept or not.
