Evil is a strong word that people now employ fairly rarely. Many people believe these days that God is omnipotent,omniscient and good and that what we deem to be bad or evil in the world is no reason for abandoning belief in God. It is an intellectual or theoretical problem not one where the focus is on how one might bring about some desirable goal (a practical matter).
Professor Davies says we should tackle this problem by attending to the basics, by asking whether there is a God and then by asking what is God? He starts by summarizing the arguments so far (from Seneca to the present day). He then moves to what he describes as the basics and demonstrates that much of what has been written about on the topic of evil is in fact irrelevant or just plain wrong.
Finally, though many theologians argue that evil is a mystery, Davies argues that this too is wrong and a cop out. We should rather be concerned with the problem (or mystery) of good. The real issue is "Why is there not more good than there is?" From the discussion Aquinas emerges as a hero (as filtered through analytical philosophy) but many moderns thinkers do not emerge so well. Davies effectively picks holes in the arguments of Peter Geach, Paul Helm, Richard Swinburne and even Mary Baker Eddy.
This is a lively book on a tricky subject, written at all times with humour and much practical example.
