“Friendship is unnecessary, like philosophy, like art.... It has no survival value; rather it is one of those things which give value to survival.”

“There 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.”

“Critics who treat 'adult' as a term of approval, instead of as a merely descriptive term, cannot be adult themselves. To be concerned about being grown up, to admire the grown up because it is grown up, to blush at the suspicion of being childish; these things are the marks of childhood and adolescence. And in childhood and adolescence they are, in moderation, healthy symptoms. Young things ought to want to grow. But to carry on into middle life or even into early manhood this concern about being adult is a mark of really arrested development. When I was ten, I read fairy tales in secret and would have been ashamed if I had been found doing so. Now that I am fifty I read them openly. When I became a man I put away childish things, including the fear of childishness and the desire to be very grown up.”

“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.”

“This moment contains all moments.”

“I object to that remark very strongly! - The Magician's Nephew”

“Friendship is the greatest of worldly goods. Certainly to me it is the chief happiness of life. If I had to give a piece of advice to a young man about a place to live, I think I should say, 'sacrifice almost everything to live where you can be near your friends.” 

“If you want to get warm you must stand near the fire: if you want to be wet you must get into the water. If you want joy, power, peace, eternal life, you must get close to, or even into, the thing that has them.”

“Our Father refreshes us on the journey with some pleasant inns, but will not encourage us to mistake them for home.”

“Telling us to obey instinct is like telling us to obey 'people.' People say different things: so do instincts. Our instincts are at war. If it is held that the instinct for preserving the species should always be obeyed at the expense of other instincts, whence do we derive this rule of precedence? To listen to that instinct speaking in its own case and deciding in its own favour would be rather simple minded. Each instinct, if you listen to it, will claim to be gratified at the expense of all the rest. By the very act of listening to one rather than to others we have already prejudged the case. If we did not bring to the examination of our instincts a knowledge of their comparative dignity we could never learn it from them. And that knowledge cannot itself be instinctive: the judge cannot be one of the parties judged: or, if he is, the decision is worthless and there is no ground for placing preservation of the species above self-preservation or sexual appetite.”

“I believe in Christianity as I believe that the sun has risen: not only because I see it, but because by it I see everything else.”

“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?”

“I think He made one law of that kind in order that there might be obedience. In all these other matters what you call obeying Him is but doing what seems good in your own eyes also. Is love content with that?”

“When the author walks onto the stage, the play is over”

“One word, Ma'am," he said, coming back from the fire; limping, because of the pain. "One word. All you've been saying is quite right, I shouldn't wonder. I'm a chap who always liked to know the worst and then put the best face I can on it. So I won't deny any of what you said. But there's one more thing to be said, even so. Suppose we have only dreamed, or made up, all those things-trees and grass and sun and moon and stars and Aslan himself. Suppose we have. Then all I can say is that, in that case, the made-up things seem a good deal more important than the real ones. Suppose this black pit of a kingdom of yours is the only world. Well, it strikes me as a pretty poor one. And that's a funny thing, when you come to think of it. We're just babies making up a game, if you're right. But four babies playing a game can make a play-world which licks your real world hollow. That's why I'm going to stand by the play world. I'm on Aslan's side even if there isn't any Aslan to lead it. I'm going to live as like a Narnian as I can even if there isn't any Narnia. So, thanking you kindly for our supper, if these two gentlemen and the young lady are ready, we're leaving your court at once and setting out in the dark to spend our lives looking for Overland. Not that our lives will be very long, I should think; but that's a small loss if the world's as dull a place as you say.”
