“The love of knowledge is a kind of madness.”

“A perfect man would never act from a sense of duty; he’d always want the right thing more than the wrong one. Duty is only a substitute for love (of God and of other people) like a crutch which is a substitute for a leg. Most of us need the crutch at times; but of course it is idiotic to use the crutch when our own legs (our own loves, tastes, habits etc.) can do the journey on their own.”

“Nothing, not even the best and noblest, can go on as it now is. Nothing, not even what is lowest and most bestial, will not be raised again if it submits to death. It is sown a natural body, it is raised a spiritual body. Flesh and blood cannot come to the Mountains [heaven]. Not because they are too rank, but because they are too weak. What is a Lizard compared with a stallion? Lust is a poor, weak, whimpering whispering thing compared with that richness and energy of desire which will arise when lust has been killed.”

“And as Jill gazed at its motionless bulk, she realized that she might as well have asked the whole mountain to move aside for her convenience.”

“Any amount of theology can now be smuggled into people's minds under the cover of fiction without their knowing it.”

“Talk to me about the truth of religion and I'll listen gladly. Talk to me about the duty of religion and I'll listen submissively. But don't come talking to me about the consolations of religion or I shall suspect that you don't understand.”

“Free will, though it makes evil possible, also makes possible any love or goodness or joy worth having.”

“You have not chosen one another, but I have chosen you for one another.”

“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?”

“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.”

“My own plans are made. While I can, I sail east in the Dawn Treader. When she fails me, I paddle east in my coracle. When she sinks, I shall swim east with my four paws. And when I can swim no longer, if I have not reached Aslan’s country, or shot over the edge of the world into some vast cataract, I shall sink with my nose to the sunrise.”

“Milton was right,’ said my Teacher. ‘The choice of every lost soul can be expressed in the words “Better to reign in Hell than serve in Heaven.” There is always something they insist on keeping even at the price of misery. There is always something they prefer to joy—that is, to reality.”

“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.”

“You are guilty of no evil, Ransom of Thulcandra, except a little fearfulness. For that, the journey you go on is your pain, and perhaps your cure: for you must be either mad or brave before it is ended.”

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