„There is one thing, and only one, in the whole universe which we know more about than we could learn from external observation. That one thing is Man. We do not merely observe men, we are men. In this case we have, so to speak, inside information; we are in the know.“
— Clive Staples Lewis Christian apologist, novelist, and Medievalist 1898 - 1963
Mere Christianity (1952), Book I, Chapter 4, "What Lies behind the Law"
