Whenever you find a man who says he does not believe in a real Right and Wrong, you will find the same man going back on this a moment later. He may break his promise to you, but if you try breaking one to him he will be complaining 'It's not fair' before you can say Jack Robinson.
C. S. LewisCreatures are not born with desires unless satisfaction for those desires exists. A baby feels hunger: well, there is such a thing as food. A duckling wants to swim: well, there is such a thing as water...If I find in myself a desire, which no experience in this world can satisfy, the most probable explanation is that I was made for another world.
C. S. LewisAs St. Paul points out, Christ never meant that we were to remain children in intelligence: on the contrary, He told us to be not only "as harmless as doves," but also "as wise as serpents." He wants a child's heart, but a grown-up's head.
C. S. LewisThe promise, made when I am in love and because I am in love, to be true to the beloved as long as I live, commits me to being true even if I cease to be in love. A promise must be about things that I can do, about actions: no one can promise to go on feeling in a certain way. He might as well promise to never have a headache or always to feel hungry.
C. S. LewisThere is one vice of which no man in the world is free; which every one in the world loathes when he sees it in someone else; and of which hardly any people, except Christians, ever imagine that they are guilty themselves. […] There is no fault which makes a man more unpopular, and no fault which we are more unconscious of in ourselves.[…]The vice I am talking of is Pride or Self-Conceit: and the virtue opposite to it, in Christian morals, is called Humility.
C. S. LewisBelieving things on authority only means believing them because you have been told them by someone you think trustworthy. Ninety-nine per cent of the things you believe are believed on authority... Every historical event in the world is believed on authority. None of us has seen the Norman Conquest or the defeat of the Armada.
