C.S. Lewis writes about his years as an atheist: “My argument against God was that the universe was so cruel and unjust. But how had I got this idea of just and unjust? A man doesn’t call a line crooked unless he has some idea of a straight line. What was I comparing this universe to when I was calling it unjust?…Of course I could have given up my idea of justice by saying it was nothing but a private idea of my own. But if I did that, then my argument against God collapsed too—for the argument depended on saying that the world was really unjust, not that it just didn’t happen to please my fancies. Thus in the very act of trying to prove that God didn’t exist—in other words, that the whole of reality was senseless—I found I was forced to assume that one part of reality—namely my idea of justice—was full of sense. Consequently atheism turns out to be too simple. If the whole universe has no meaning, we should never have found out…” — Broadcast Talks, pp. 40-41
