“Good and evil both increase at compound interest.”

“How monotonously alike all the great tyrants and conquerors have been; how gloriously different are the saints.”

“The Moral Law isn't any one instinct or any set of instincts: it is something which makes a kind of tune (the tune we call goodness or right conduct) by directing the instincts. (...) The most dangerous thing you can do is to take any one impulse of your own nature and set it up as the thing you ought to follow at all costs. There's not one of them which won't make us into devils if we set it up as an absolute guide. You might think love of humanity in general was safe, but it isn't. If you leave out justice you'll find yourself breaking agreements and faking evidence in trials 'for the sake of humanity,' and become in the end a cruel and treacherous man.”

“And for all I can tell, the only difference is that what many see we call a real thing, and what only one sees we call a dream. But things that many see may have no taste or moment in them at all, and things that are shown only to one may be spears and water-spouts of truth from the very depth of truth.”

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

“But, first, remember, remember, remember the signs. Say them to yourself when you wake in the morning and when you lie down at night, and when you wake in the middle of the night. And whatever strange things may happen to you, let nothing turn your mind from following the signs. And secondly, I give you a warning. Here on the mountain I have spoken to you clearly: I will not often do so down in Narnia. Here on the mountain, the air is clear and your mind is clear; as you drop down into Narnia, the air will thicken. Take great care that it does not confuse your mind. And the signs which you have learned here will not look at all as you expect them to look, when you meet them there. That is why it is so important to know them by heart and pay no attention to appearances. Remember the signs and believe the signs. Nothing else matters.”

“If the solar system was brought about by an accidental collision, then the appearance of organic life on this planet was also an accident, and the whole evolution of Man was an accident too. If so, then all our present thoughts are mere accidents--the accidental by-product of the movement of atoms. And this holds for the thoughts of the materialists and astronomers as well as for anyone else's. But if their thoughts--i.e. of materialism and astronomy--are merely accidental by-products, why should we believe them to be true? I see no reason for believing that one accident should be able to give me a correct account of all the other accidents. It's like expecting that the accidental shape taken by the splash when you upset a milkjug should give you a correct account of how the jug was made and why it was upset.”

“She remembered, as every sensible person does, that you should never never shut yourself up in a wardrobe.”

“Because, as we know, almost anything can be read into any book if you are determined enough. This will be especially impressed on anyone who has written fantastic fiction. He will find reviewers, both favourable and hostile, reading into his stories all manner of allegorical meanings which he never intended. (Some of the allegories thus imposed on my own books have been so ingenious and interesting that I often wish I had thought of them myself.)”

“It is a serious thing to live in a society of possible gods and goddesses, to remember that the dullest most uninteresting person you can talk to may one day be a creature which,if you saw it now, you would be strongly tempted to worship, or else a horror and a corruption such as you now meet, if at all, only in a nightmare. All day long we are, in some degree helping each other to one or the other of these destinations. It is in the light of these overwhelming possibilities, it is with the awe and the circumspection proper to them, that we should conduct all of our dealings with one another, all friendships, all loves, all play, all politics. There are no ordinary people. You have never talked to a mere mortal. Nations, cultures, arts, civilizations - these are mortal, and their life is to ours as the life of a gnat. But it is immortals whom we joke with, work with, marry, snub, and exploit - immortal horrors or everlasting splendors.”

“Kids like us don't often have the chance of meeting a great warrior like you. Would you have a little fencing match with me? It would be frightfully decent.”

“A man is never so proud as when striking an attitude of humility.”

“Ah, you've come over the water. Powerful wet stuff, ain't it?”

“Here at last is the thing I was made for.”

“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.”
