“Her absence is like the sky, spread over everything. But no, that is not quite accurate. There is one place where her absence comes locally home to me, and it is a place I can't avoid. I mean my own body. It had such a different importance while it was the body of H.'s lover. Now it's like an empty house.”

“Nonsense remains nonsense even when we talk it about God.”

“It is better to forget about yourself altogether.”

“Love is something more stern and splendid than mere kindness.”

“If we cut up beasts simply because they cannot prevent us and because we are backing our own side in the struggle for existence, it is only logical to cut up imbeciles, criminals, enemies, or capitalists for the same reasons.”

“Progress means getting nearer to the place you want to be. And if you have taken a wrong turning, then to go forward does not get you any nearer. If you are on the wrong road, progress means doing an about-turn and walking back to the right road; and in that case the man who turns back soonest is the most progressive man.”

“I have learned now that while those who speak about one's miseries usually hurt, those who keep silence hurt more.” 

“You've no idea how good an old joke sounds when you take it out again after a rest of five or six hundred years.”

“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.”

“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.”

“Nor am I greatly moved by jocular inquiries such as, 'Where will you put all the mosquitoes?' -- a question to be answered on its own level by pointing out that, if the worst came to worst, a heaven for mosquitoes and a hell for men could very conveniently be combined.”

“The 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.” 

“But I cannot tell that to this old sinner, and I cannot comfort him either; he has made himself unable to hear my voice. If I spoke to him, he would hear only growlings and roarings. Oh, Adam's son, how cleverly you defend yourself against all that might do you good!”

“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?”

“Prosperity knits a man to the world. He feels that he is finding his place in it, while really it is finding its place in him.”
