“A moderated religion is as good for us as no religion at all—and more amusing.” 

“Whatever you do, He will make good of it. But not the good He had prepared for you if you had obeyed him.”

“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?”

“No more I do, your Majesty. But what's that got to do with it? I might as well die on a wild goose chase as die here.”

“Your real, new self (which is Christ's and also yours, and yours just because it is His) will not come as long as you are looking for it. It will come when you are looking for Him. Does that sound strange? The same principle holds, you know, for more everyday matters. Even in social life, you will never make a good impression on other people until you stop thinking about what sort of impression you are making. Even in literature and art, no man who bothers about originality will ever be original whereas if you simply try to tell the truth (without caring twopence how often it has been told before) you will, nine times out of ten, become original without ever having noticed it. The principle runs through all life from top to bottom, Give up yourself, and you will find your real self. Lose your life and you will save it. Submit to death, death of your ambitions and favourite wishes every day and death of your whole body in the end submit with every fibre of your being, and you will find eternal life. Keep back nothing. Nothing that you have not given away will be really yours. Nothing in you that has not died will ever be raised from the dead. Look for yourself, and you will find in the long run only hatred, loneliness, despair, rage, ruin, and decay. But look for Christ and you will find Him, and with Him everything else thrown in.”

“Life is too deep for words, so don't try to describe it, just live it. Actually this quote doesn't sound like C.S. Lewis at all. Can anyone provide a source?”

“The game is to have them all running about with fire extinguishers when there is a flood, and all crowding to that side of the boat which is already nearly gunwale under.”

“Would it not be better to be dead than to have this horrible fear that Aslan has come and is not like the Aslan we have believed in and longed for? It is as if the sun rose one day and were a black sun.”

“It is easy to acknowledge, but almost impossible to realize for long, that we are mirrors whose brightness, if we are bright, is wholly derived from the sun that shines upon us.”

“We must lay before him what is in us; not what ought to be in us.”

“Oh, I can see it happening, age after age, and growing worse the more you reveal your beauty: the son turning his back on the mother and the bride on her groom, stolen away by this everlasting calling, calling, calling of the gods. Taken where we can't follow. It would be far better for us if you were foul and ravening. We'd rather you drank their blood than stole their hearts. We'd rather they were ours and dead than yours and made immortal.”

“It has actually become very necessary in our time to rebut the theory that every firm and serious friendship is really homosexual.”

“But that would be putting the clock back," gasped the Governor. "Have you no idea of progress, of development?" "I have seen them both in an egg," said Caspian. "We call it Going bad in Narnia.” 

“Then Hwin, though shaking all over, gave a strange little neigh and trotted across to the Lion.  "Please," she said, "you're so beautiful. You may eat me if you like. I'd sooner be eaten by you than fed by anyone else.”

“Further up and further in”
