“He has room for people with very little sense, but He wants everyone to use what sense they have.”

“Once a king or queen of Narnia, always a king or queen of Narnia.”

“If we let ourselves, we shall always be waiting for some distraction or other to end before we can really get down to our work. The only people who achieve much are those who want knowledge so badly that they seek it while the conditions are still unfavorable. Favorable conditions never come.”

“But those two circles, above all the point at which they touched, are the very thing I am mourning for, homesick for, famished for. You tell me 'she goes on.' But my heart and body are crying out, come back, come back. Be a circle, touching my circle on the plane of Nature. But I know this is impossible. I know that the thing I want is exactly the thing I can never get.”

“Further up and further in” 

“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.”

“We need not despair even in our worst, for our failures are forgiven. The only fatal thing is to sit down content with anything less than perfection.”

“Thomas Aquinas said of suffering, as Aristotle had said of shame, that it was a thing not good in itself; but a thing which might have a certain goodness in particular circumstances. That is to say, if evil is present, pain at recognition of the evil, being a kind of knowledge, is relatively good.”

“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.”

“I expect you have seen someone put a a lighted match to a bit of newspaper which is propped up in a grate against an unlit fire. And for a second nothing seems to have happened; and then you notice a tiny steak of flame creeping along the edged of the newspaper. It was like that now.”

“Be comforted, small one, in your smallness. He lays no merit on you. Receive and be glad.”

“My dear young lady,' said the professor...'there is one plan which no one has yet suggested and which is well worth trying.' 'What's that?' said Susan. 'We might all try minding our own business...”

“Atheism turns out to be too simple. If the whole universe has no meaning, we should never have found out that it has no meaning...”

“Once a King in Narnia, always a King in Narnia. But don't go trying to use the same route twice. Indeed, don't try to get there at all. It'll happen when you're not looking for it. And don't talk too much about it even among yourselves. And don't mention it to anyone else unless you find that they've had adventures of the same sort themselves. What's that? How will you know? Oh, you'll know all right. Odd things, they say-even their looks-will let the secret out. Keep your eyes open. Bless me, what do they teach them at these schools." -The Professor”

“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.”
