“Evil can be undone, but it cannot 'develop' into good. Time does not heal it. The spell must be unwound, bit by bit, 'with backward mutters of dissevering power' - or else not.”

“Kindness consents very readily to the removal of its object – we have all met people whose kindness to animals is constantly leading them to kill animals lest they should suffer. Kindness, merely as such, cares not whether its object becomes good or bad, provided only that it escapes suffering.”

“True friends don’t spend time gazing into each other’s eyes. They may show great tenderness towards each other but they face in the same direction - toward common projects, goals - above all, towards a common Lord.”

“But in Friendship, being free of all that, we think we have chosen our peers. In reality, a few years' difference in the dates of our births, a few more miles between certain houses, the choice of one university instead of another, posting to different regiments, the accident of a topic being raised or not raised at a first meeting—any of these chances might have kept us apart. But, for a Christian, there are, strictly speaking, no chances. A secret Master of the Ceremonies has been at work. Christ, who said to the disciples "Ye have not chosen me, but I have chosen you," can truly say to every group of Christian friends "You have not chosen one another but I have chosen you for one another." The Friendship is not a reward for our discrimination and good taste in finding one another out. It is the instrument by which God reveals to each the beauties of all the others. They are no greater than the beauties of a thousand other men; by Friendship God opens our eyes to them. They are, like all beauties, derived from Him, and then, in a good Friendship, increased by Him through the Friendship itself, so that it is His instrument for creating as well as for revealing.”

“Since it is so likely that (children) will meet cruel enemies, let them at least have heard of brave knights and heroic courage. Otherwise you are making their destiny not brighter but darker.”

“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.”

“Things always work according to their nature.”

“By gum,' said Digory, 'Don't I just wish I was big enough to punch your head!”

“Here are beauties which pierce like swords or burn like cold iron. Here is a book which will break your heart."

“In a sort of ghastly simplicity we remove the organ and demand the function. We make men without chests and expect of them virtue and enterprise. We laugh at honour and are shocked to find traitors in our midst. We castrate and bid the geldings be fruitful.”

“Things never happen the same way twice.”

“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.”

“What can you ever really know of other people's souls — of their temptations, their opportunities, their struggles? One soul in the whole of creation you do know: and it is the only one whose fate is placed in your hands. If there is a God, you are, in a sense, alone with Him.”

“A moderated religion is as good for us as no religion at all—and more amusing.” 

“[Repentance] means unlearning all the self-conceit and self -will that we have been training ourselves into... It means killing part of yourself, under-going a kind of death.”
