“Supposing you hear a cry for help from a man in danger. You will probably feel two desires - one a desire to give help (due to your herd instinct), the other a desire to keep out of danger (due to the instinct for self-preservation). But you will find inside you, in addition to these two impulses, a third thing which tells you that you ought to follow the impulse to help, and suppress the impulse to run away. Now this thing that judges between two instincts, that decides which should be encouraged, cannot itself be either of them. You might as well say that the sheet of music which tells you, at a given moment, to play one note on the piano and not another, is itself one of the notes on the keyboard. The Moral Law tells us the tune we have to play: our instincts are merely the keys.”

“He does not despise real woods because he has read of enchanted woods; the reading makes all real woods a little enchanted.”

“We cannot understand. The best is perhaps what we understand least.”

“Being in love is a good thing, but it is not the best thing. There are many things below it, but there are also things above it. You cannot make it the basis of a whole life. It is a noble feeling, but it is still a feeling. Now no feeling can be relied on to last in its full intensity, or even to last at all. Knowledge can last, principles can last, habits can last but feelings come and go. And in fact, whatever people say, the state called ‘being in love’ usually does not last. If the old fairy-tale ending ‘They lived happily ever after’ is taken to mean ‘They felt for the next fifty years exactly as they felt the day before they were married,’ then it says what probably never was nor ever would be true, and would be highly undesirable if it were. Who could bear to live in that excitement for even five years? What would become of your work, your appetite, your sleep, your friendships? But, of course, ceasing to be ‘in love’ need not mean ceasing to love. Love in this second sense — love as distinct from ‘being in love’ — is not merely a feeling. It is a deep unity, maintained by the will and deliberately strengthened by habit; reinforced by (in Christian marriages) the grace which both partners ask, and receive, from God. They can have this love for each other even at those moments when they do not like each other; as you love yourself even when you do not like yourself. They can retain this love even when each would easily, if they allowed themselves, be ‘in love’ with someone else. ‘Being in love’ first moved them to promise fidelity: this quieter love enables them to keep the promise. it is on this love that the engine of marriage is run: being in love was the explosion that started it.”

“Read and Re-Read--"Re-reading, we always find a new book.” 

“Pain insists upon being attended to. God whispers to us in our pleasures, speaks in our consciences, but shouts in our pains. It is his megaphone to rouse a deaf world.”

“No interviews without appointments except between nine and ten PM on the second Saturdays.”

“Please,' she said, 'You're so beautiful. You may eat me if you like. I'd rather be eaten by you than fed by anyone else.”

“People are often worried. They are told they ought to love God. They cannot find any such feeling in themselves. What are they to do? The answer is the same as before. Act as if you did. Do not sit trying to manufacture feelings. Ask yourself, ‘If I were sure that I loved God, what would I do?’ When you have found the answer, go and do it.”

“The love of knowledge is a kind of madness.”

“Joy is not a substitute for sex; sex is very often a substitute for Joy. I sometimes wonder whether all pleasures are not substitutes for Joy.”

“In your life you meet people. Some you never think about again. Some, you wonder what happened to them. There are some that you wonder if they ever think about you. And then there are some that you wish you never have to think about again. But you do.”

“Indeed the safest road to Hell is the gradual one--the gentle slope, soft underfoot, without sudden turnings, without milestones, without signposts,...Your affectionate uncle, Screwtape.”

“Hope is one of the Theological virtues. This means that a continual looking forward to the eternal world is not (as some modern people think) a form of escapism or wishful thinking, but one of the things a Christian is meant to do. It does not mean that we are to leave the present world as it is. If you read history you will find that the Christians who did most for the present world were just those who thought most of the next.”

“You thought you were going to be made into a decent little cottage: but He is building a palace. He intends to come and live in it himself. (Quoted by C.S.Lewis in Mere Christianity)”
