“God created things which had free will. That means creatures which can go wrong or right. Some people think they can imagine a creature which was free but had no possibility of going wrong, but I can't. If a thing is free to be good it's also free to be bad. And free will is what has made evil possible. Why, then, did God give them free will? Because free will, though it makes evil possible, is also the only thing that makes possible any love or goodness or joy worth having. A world of automata -of creatures that worked like machines- would hardly be worth creating. The happiness which God designs for His higher creatures is the happiness of being freely, voluntarily united to Him and to each other in an ecstasy of love and delight compared with which the most rapturous love between a man and a woman on this earth is mere milk and water. And for that they've got to be free. Of course God knew what would happen if they used their freedom the wrong way: apparently, He thought it worth the risk. (...) If God thinks this state of war in the universe a price worth paying for free will -that is, for making a real world in which creatures can do real good or harm and something of real importance can happen, instead of a toy world which only moves when He pulls the strings- then we may take it it is worth paying.”

“Don't use words too big for the subject. Don't say infinitely when you mean very; otherwise you'll have no word left when you want to talk about something really infinite.”

“Quarrelling means trying to show that the other man is in the wrong. (And) There is no sense in trying to do that unless you and he had some sort of agreement as to what Righ and Wrong are...”

“You can’t go on “seeing through” things forever. The whole point of seeing through something is to see something through it. To “see through” all things is the same as not to see.”

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

“I could never have gone far in any science because on the path of every science the lion Mathematics lies in wait for you.”

“Let's pray that the human race never escapes Earth to spread its iniquity elsewhere.”

“My good Horse," said the Hermit, who had approached them unnoticed because his bare feet made so little noise on that sweet, dewy grass. "My good Horse, you've lost nothing but your self-conceit. No, no, cousin. Don't put back your ears and shake your mane at me. If you are really so humbled as you sounded a minute ago, you must learn to listen to sense. You're not quite the great Horse you had come to think, from living among poor dumb horses. Of course you were braver and cleverer than them. You could hardly help being that. It doesn't follow that you'll be anyone very special in Narnia. But as long as you know you're nobody very special, you'll be a very decent sort of Horse, on the whole, and taking one thing with another.”

“It takes courage to live through suffering; and it takes honesty to observe it.”

“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.”

“Why should your Majesty expect it? 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 in some vast cataract, I shall sink with my nose to the sunrise and Peepiceek will be head of the talking mice in Narnia.”

“…the greatest service we can do to education today is to teach fewer subjects. No one has time to do more than a very few things well before he is twenty, and when we force a boy to be a mediocrity in a dozen subjects, we destroy his standards, perhaps for life.” 

“No sooner do we believe that God loves us than there is an impulse to believe that He does so, not because He is Love, but because we are intrinsically lovable. The Pagans obeyed this impulse unabashed; a good man was "dear to the gods" because he was good. We, being better taught, resort to subterfuge. Far be it from us to think that we have virtues for which God could love us. But then, how magnificently we have repented! As Bunyan says, describing his first and illusory conversion, "I thought there was no man in England that pleased God better than I." Beaten out of this, we next offer our own humility to God's admiration. Surely He'll like that? Or if not that, our clear-sighted and humble recognition that we still lack humility. Thus, depth beneath depth and subtlety within subtelty, there remains some lingering idea of our own, our very own attractiveness. It is easy to acknowledge, but almost impossible to realize for long, that we are mirrors whose brightness, if we are bright, is wholly derived from the sun that shines upon us. Surely we must have a little--however little--native luminosity? Surely we can't be quite creatures?

“The Christian is in a different position from other people who are trying to be good. They hope, by being good, to please God if there is one; or — if they think there is not — at least they hope to deserve approval from good men. But the Christian thinks any good he does comes from the Christ-life inside him. He does not think God will love us because we are good, but that God will make us good because He loves us; just as the roof of a greenhouse does not attract the sun because it is bright, but becomes bright because the sun shines on it.”

“You can do more with a castle in a story than with the best cardboard castle that ever stood on a nursery table.”
