“Next to the Blessed Sacrament itself, your neighbor is the holiest object presented to your senses.”

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

“If you run now, without a moment's rest, you will still be in time to warn King Lune." Shasta's heart fainted at these words for he felt he had no strength left. And he writhed inside at what seemed the cruelty and unfairness of the demand. He had not yet learned that if you do one good deed your reward usually is to be set to do another and harder and better one. But all he said out loud was: "Where is the King?" The Hermit turned and pointed with his staff. "Look," he said. "There is another gate, right opposite to the one you entered by. Open it and go straight ahead: always straight ahead, over level or steep, over smooth or rough, over dry or wet. I know by my art that you will find King Lune straight ahead. But run, run: always run.”

“Read and Re-Read--"Re-reading, we always find a new book.” 

“To the glistening eastern sea, I give you Queen Lucy the Valiant. To the great western woods, King Edmund the Just. To the radiant southern sun, Queen Susan the Gentle. And to the clear northern skies, I give you King Peter the Magnificent. Once a king or queen of Narnia, always a king or queen of Narnia. May your wisdom grace us until the stars rain down from the heavens.”

“If a mother is mourning not for what she has lost but for what her dead child has lost, it is a comfort to believe that the child has not lost the end for which it was created. And it is a comfort to believe that she herself, in losing her chief or only natural happiness, has not lost a greater thing, that she may still hope to "glorify God and enjoy Him forever." A comfort to the God-aimed, eternal spirit within her. But not to her motherhood. The specifically maternal happiness must be written off. Never, in any place or time, will she have her son on her knees, or bathe him, or tell him a story, or plan for his future, or see her grandchild.”

“If my house has collapsed at one blow, that is because it was a house of cards. The faith which 'took these things into account' was not faith but imagination.”

“The human mind is generally far more eager to praise and dispraise than to describe and define. It wants to make every distinction a distinction of value; hence those fatal critics who can never point out the differing quality of two poets without putting them in an order of preference as if they were candidates for a prize.”

“But very quickly they all became grave again: for, as you know, there is a kind of happiness and wonder that makes you serious. It is too good to waste on jokes.”

“All names will soon be restored to their proper owners.”

“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.”

“Every age has its own outlook. It is specially good at seeing certain truths and specially liable to make certain mistakes. We all, therefore, need the books that will correct the characteristic mistake of our own period. And that means the old books.”

“His Omnipotence means power to do all that is intrinsically possible, not to do the intrinsically impossible. You may attribute miracles to Him, but not nonsense. There is no limit to His power. If you choose to say, 'God can give a creature free will and at the same time withhold free will from it,' you have not succeeded in saying anything about God: meaningless combinations of words do not suddenly acquire meaning simply because we prifex to them the two other words, 'God can.' It remains true that all things are possible with God: the intrinsic impossibilities are not things but nonentities. It is no more possible for God than for the weakest of His creatures to carry out both of two mutually exclusive alternatives; not because His power meets an obstacle, but because nonsense remains nonsense even when we talk it about God.”

“Music. A meaningless acceleration in the rhythm of celestial experience.”

“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?”
