Orthodoxy by GK Chesterton - Chapter 5

"But all the optimism of the age had been false and disheartening for this reason, that it had always been trying to prove that we fit in to the world. 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."
