The Christian optimism is based on the fact that we do not fit in to the world. I had tried to be happy by telling myself that man is an animal, like any other which sought its meat from God. But now I really was happy, for I had learnt that man is a monstrosity. I had been right in feeling all things as odd, for I myself was at once worse and better than all things. The optimist’s pleasure was prosaic, for it dwelt on the naturalness of everything; the Christian pleasure was poetic, for it dwelt on the unnaturalness of everything in the light of the supernatural. The modern philosopher had told me again and again that I was in the right place, and I had still felt depressed even in acquiescence. But I had heard that I was in the wrong place, and my soul sang for joy, like a bird in spring. The knowledge found out and illuminated forgotten chambers in the dark house of infancy. I knew now why grass had always seemed to me as queer as the green beard of a giant, and why I could feel homesick at home.
