“God made us: invented us as a man invents an engine. A car is made to run on petrol, and it would not run properly on anything else. Now God designed the human machine to run on Himself. He Himself is the fuel our spirits were designed to burn, or the food our spirits were designed to feed on. There is no other. That is why it is just no good asking God to make us happy in our own way without bothering about religion. God cannot give us a happiness and peace apart from Himself, because it is not there.”

“Pure, spiritual, intellectual love shot from their faces like barbed lightning. It was so unlike the love we experience that its expression could easily be mistaken for ferocity.”

“If you think of this world as a place simply intended for our happiness, you find it quite intolerable: think of it as a place for training and correction and it's not so bad.”

“Each time you fall He'll pick you up. He knows your own efforts are never going to bring you anywhere near perfection”

“It is funny how mortals always picture us as putting things into their minds: in reality our best work is done by keeping things out.”

“If all experienced God in the same way and returned Him an identical worship, the song of the Church triumphant would have no symphony, it would be played like an orchestra in which all instruments played the same note.”

“Write about what really interests you, whether it is real things or imaginary things, and nothing else.”

“If things are real, they're there all the time.”

“For me, reason is the natural organ of truth; but imagination is the organ of meaning. Imagination, producing new metaphors or revivifying old, is not the cause of truth, but its condition.”

“Friend, I am not suggesting at all. You see, I know now. Let us be frank. Our opinions were not honestly come by. We simply found ourselves in contact with a certain current of ideas and plunged into it because it seemed modern and successful. At College, you know, we just started automatically writing the kind of essays that got good marks and saying the kind of things that won applause. When, in our whole lives, did we honestly face, in solitude, the one question on which all turned: whether after all the Supernatural might not in fact occur? When did we put up one moment's real resistance to the loss of our faith?”

“We were promised sufferings. They were part of the program. We were even told, 'Blessed are they that mourn,' and I accept it. I've got nothing that I hadn't bargained for. Of course it is different when the thing happens to oneself, not to others, and in reality, not imagination.”

“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.”

“I, or any mortal at any time, may be utterly mistaken as to the situation he is really in.”

“Gone! ...And you and I quite crestfallen.”

“I wrote this story for you, but when I began it I had not realized that girls grow quicker than books. As a result you are already too old for fairy tales, and by the time it is printed and bound you will be older still. But some day you will be old enough to start reading fairy tales again. You can then take it down from some upper shelf, dust it, and tell me what you think of it. I shall probably be too deaf to hear, and too old to understand a word you say, but I shall still be your affectionate Godfather, C. S. Lewis.”
