Book IV is the turning point in the theodicy, in the first chapter Boethius is truly puzzled by the presence of evil in the world. "But the greatest cause of my sadness is really this - the fact that in spite of a good helmsman to guide the world, evil can still exist and even pass unpunished That this can happen in the realm of an omniscient and omnipotent God who wills only good, is beyond perplexity and complaint."

In The Consolation of Philosophy, Boethius uses good vs. evil argument in an objective, metaphysical view, on an abstract level. Good being the all-powerful God and evil being nothing. Parallel to that view, there is good vs. bad, which is presented from a human viewpoint. While the good has similar meaning in both arguments, Boethius makes a clear distinction between evil and bad. What might be perceived to be a bad thing from a human point of view is actually turning a bad experience into something good, therefore it is not evil.
