“There is one vice of which no man in the world is free; which every one in the world loathes when he sees it in someone else; and of which hardly any people, except Christians, ever imagine that they are guilty themselves. […] There is no fault which makes a man more unpopular, and no fault which we are more unconscious of in ourselves.[…]The vice I am talking of is Pride or Self-Conceit: and the virtue opposite to it, in Christian morals, is called Humility.”

“The sin both of men and of angels, was rendered possible by the fact that God gave us free will.”

“It may be possible for each to think too much of his own potential glory hereafter; it is hardly possible for him to think too often or too deeply about that of his neighbor. The load, or weight, or burden of my neighbor's glory should be laid daily on my back, a load so heavy that only humility can carry it, and the backs of the proud will be broken. ...  "It is in light of these overwhelming possibilities, it is with the awe and the circumspection proper to them, that we should conduct all 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. ... Next to the Blessed Sacrament itself, your neighbor is the holiest object presented to your senses.”

“But that would be putting the clock back," gasped the Governor. "Have you no idea of progress, of development?" "I have seen them both in an egg," said Caspian. "We call it Going bad in Narnia.” 

“If you do not take the distinction between good and bad very seriously, then it is easy to say that anything you find in this world is a part of God. But, of course, if you think some things really bad, and God really good, then you cannot talk like that. You must believe that God is separate from the world and that some of the things we see in it are contrary to His will.”

“You have no idea what an appetite it gives one, being executed.”

“Miracles do not, in fact, break the laws of nature.”

“[The devil] always sends errors into the world in pairs--pairs of opposites. And he always encourages us to spend a lot of time thinking which is the worse. You see why, of course? He relies on your extra dislike of the one error to draw you gradually into the opposite one.”

“If they won't write the kind of books we like to read we shall have to write them ourselves.”

“Then Hwin, though shaking all over, gave a strange little neigh and trotted across to the Lion.  "Please," she said, "you're so beautiful. You may eat me if you like. I'd sooner be eaten by you than fed by anyone else.”

“No natural feelings are high or low, holy or unholy, in themselves. They are all holy when God's hand is on the rein. They all go bad when they set up on their own and make themselves into false gods.”

“If you think of this world as a place simply intended for our happiness, you find it quite intolerable: think of it as a place for training and correction and it's not so bad.”

“Puddleglum is the name. It doesn't matter if you forget it, I can always tell you again.”

“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.”

“I write for the unlearned about things in which I am unlearned myself.”
