But Reality is not simple. It is not neat, not obvious, and not what you expect. Reality is complicated and odd and surprising. In fact, this is one of the reasons Lewis says he believes Christianity because it actually is not neat and simple and not what you would expect or what anyone would have made up. When you really look at it and really examine what Christianity says about the world, about humanity, about the God over it all, "it has just that queer twist about it that real things have."
So he says to put away these children's philosophies and over-simplified answers to the questions we are asking. Neither the problem nor the answer are simple.
The Problem: We have a universe that "contains much that is obviously bad and apparently meaningless" but which also contains "creatures like ourselves who know that it is bad and meaningless."
"The same point can be made in a different way. If Dualism is true, then the bad Power must be a being who likes badness for its own sake. But in reality we have no experience of anyone liking badness just because it is bad. The nearest we can get to it is in cruelty. But in real life people are cruel for one of two reasons- either because they are sadists, that is, because they have a sexual perversion which makes cruelty a cause of sensual pleasure to them, or else for the sake of something they are going to get out of it - money, or power, or safety. But pleasure, money, power, and safety are all, as far as they go, good things. The badness consists in pursuing them by the wrong method, or in the wrong way, or too much. I do not mean, of course, that the people who do this are not desperately wicked. I do mean that wickedness, when you examine it, turns out to be the pursuit of some good in the wrong way. You can be good for the mere sake of goodness: you cannot be bad for the mere sake of badness. You can do a kind action when you are not feeling kind and when it gives you no pleasure, simply because kindness is right; but no one ever did a cruel action simply because cruelty is wrong - only because cruelty was pleasant or useful to him. In other words badness cannot succeed even in being bad in the same way in which goodness is good. Goodness is, so to speak, itself: badness is only spoiled goodness. And there must be something good first before it can be spoiled."
How has that view helped the cause of Atheism and damaged the reputation of Christianity?
