Chisholm then sketches his own solution to the problem of evil. He says ‘Some of the evil in the world is necessary for the enhancement of goodness. And the rest of the evil is defeated’ ([B&amp;IV], 100). In a characteristically careful way, Chisholm does not assert that all the evil in this world is actually to be explained in this way. He restricts himself to suggesting that Brentano would have said such a thing, and that the conceptual machinery he has developed shows us how it is possible that the world could contain some evil even though the world was created by an omnipotent, omniscient, and benevolent god. Whether the evil in this world is in fact defeated is another question. Chisholm concludes by saying ‘The wise theodicist, I should think, would say that he doesn’t know’ ([B&amp;IV], 102).
