Anonymous has commented on the presentation of the argument from evil that Jason was kind enough to post, from The Problem of Pain.
Anon: Sounds like the typical Christian portrayal of what an atheistic outlook leads to. Supposedly, all is doom and gloom unless one buys into the idea of a supernatural being in the heavens.
VR: Where does he say this?
Anon: It's hard not to giggle when seeing how much Lewis anthropomorphized nature.
VR: Even Daniel Dennett talks about Mother Nature, (though I think he does anthropomorphize nature in a misleading way). But Lewis is just putting the case dramatically. And he is pointing to suffering as a reason for thinking that the universe is not intelligently designed by an omnipotent and perfectly good being. Similar dramatizations appear in the presentations of the argument from evil by David Hume and Bertrand Russell.
Anon: Lewis' argument falls apart here. He's made the unsupported assumption the the "world was really unjust." The problem of evil does not require such an assumption.
VR: We've been covering this issue quite a lot here. It requires some assumption about what God ought to do, which God is not doing. It presupposes an idea of what kinds of universes a perfectly good God should permit. It has, in short, a moral premise. But if the proposition "God ought to minimize suffering" is a private fancy of one's own on a level with a liking for pancakes or a dislike for Spam, we have severely weakened the argument from evil. Unless one happens to be arguing with someone with the same private fancy.
