“I do not think there is a demonstrative proof (like Euclid) of Christianity, nor of the existence of matter, nor of the good will and honesty of my best and oldest friends. I think all three are (except perhaps the second) far more probable than the alternatives. The case for Christianity in general is well given by Chesterton…As to why God doesn't make it demonstratively clear; are we sure that He is even interested in the kind of Theism which would be a compelled logical assent to a conclusive argument? Are we interested in it in personal matters? I demand from my friend trust in my good faith which is certain without demonstrative proof. It wouldn't be confidence at all if he waited for rigorous proof. Hang it all, the very fairy-tales embody the truth. Othello believed in Desdemona's innocence when it was proved: but that was too late. Lear believed in Cordelia's love when it was proved: but that was too late. 'His praise is lost who stays till all commend.' The magnanimity, the generosity which will trust on a reasonable probability, is required of us. But supposing one believed and was wrong after all? Why, then you would have paid the universe a compliment it doesn't deserve. Your error would even so be more interesting and important than the reality. And yet how could that be? How could an idiotic universe have produced creatures whose mere dreams are so much stronger, better, subtler than itself?”

“When two humans have lived together for many years it usually happens that each has tones of voice and expressions of face which are almost unendurably irritating to the other. Work on that. Bring fully into the consciousness of your patient that particular lift of his mother's eyebrows which he learned to dislike in the nursery, and let him think how much he dislikes it. Let him assume that she knows how annoying it is and does it to annoy - if you know your job he will not notice the immense improbability of the assumption. And, of course, never let him suspect that he has tones and looks which similarly annoy her. As he cannot see or hear himself, this easily managed.”

“Love, in its own nature, demands the perfecting of the beloved.”

“When the police arrived and found no lion, no broken wall, and no convicts, and the Head behaving like a lunatic, there was an inquiry into the whole thing. And in the inquiry all sorts of things about Experiment House came out, and about ten people got expelled. After that, the Head's friends saw that the Head was no use as a Head, so they got her made an Inspector to interfere with other Heads. And when they found she wasn't much good even at that, they got her into Parliament where she lived happily ever after.”

“this is a book about something”

“The vice I am talking of is Pride or Self-Conceit: and the virtue opposite to it, in Christian morals, is called Humility...According to Christian teachers, the essential vice, the utmost evil, is Pride. Unchastity, anger, greed, drunkenness, and all that, are mere flea bites in comparison: it was through Pride that the devil became the devil: Pride leads to every other vice: it is the complete anti-God state of mind.”

“Come, live with me and you'll know me.”

“They stormed and jeered at one another in long meaningless words of about twenty syllables each.”

“Reason is the natural order of truth; but imagination is the organ of meaning.”

“Indeed the safest road to Hell is the gradual one--the gentle slope, soft underfoot, without sudden turnings, without milestones, without signposts,...Your affectionate uncle, Screwtape.”

“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?”

“This world is a great sculptor’s shop. We are the statues and there’s a rumor going around the shop that some of us are someday going to come to life.”

“A sum can be put right: but only by going back till you find the error and working it afresh from that point, never by simply going on.”

“Suppose that the earthly lives she and I shared for a few years are in reality only the basis for, or prelude to, or earthly appearance of, two unimaginable, supercosmic, eternal somethings.”

“And Dimble, who had been sitting with his face drawn, and rather white, between the white faces of the two women, and his eyes on the table, raised his head, and great syllables of words that sounded like castles came out of his mouth. Jane felt her hear leap and quiver at them. Everything else in the room seemed to have been intensely quiet; even the bird, and the bear, and the cat, were still, staring at the speaker. The voice did not sound like Dimble's own: it was as if the words spoke themselves through him from some strong place at a distance--or as if they were not words at all but present operations of God, the planets, and the Pendragon. For this was the language spoken before the Fall and beyond the Moon and the meanings were not given to the syllables by chance, or skill, or long tradition, but truly inherent in them as the shape of the great Sun is inherent in the little waterdrop. This was Language herself, as she first sprang at Maleldil's bidding out of the molten quicksilver of the first star called Mercury on Earth, but Viritrilbia in Deep Heaven.”
