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

“There is nothing indulgent about the Moral Law. It is as hard as nails. It tells you to do the straight thing and it does not seem to care how painful, or dangerous, or difficult it is to do.”

“The use of fashions in thought is to distract men from their real dangers. We direct the fashionable outcry of each generation against those vices of which it is in the least danger, and fix its approval on the virtue that is nearest the vice which we are trying to make endemic. The game is to have them all running around with fire extinguishers whenever there’s a flood; and all crowding to that side of the boat which is already nearly gone under.”

“The most precious gift that marriage gave me was the constant impact of something very close and intimate, yet all the time unmistakably other, resistant - in a word, real.”

“The Tao, which others may call Natural Law or Traditional Morality or the First Principles of Practical Reason or the First Platitudes, is not one among a series of possible systems of value. It is the sole source of all value judgments. If it is rejected, all value is rejected. If any value is retained, it is retained. The effort to refute it and raise a new system of value in its place is self-contradictory. There has never been, and never will be, a radically new judgment of value in the history of the world. What purport to be new systems or…ideologies…all consist of fragments from the Tao itself, arbitrarily wrenched from their context in the whole and then swollen to madness in their isolation, yet still owing to the Tao and to it alone such validity as they posses.”

“I was with book, as a woman is with child.”

“Caspian felt sure that he would hate the new Tutor, but when the new Tutor arrived about a week later he turned out to be the sort of person it is almost impossible not to like. He was the smallest, and also the fattest, man Caspian had ever seen. He had a long, silvery, pointed beard which came down to his waist, and his face, which was brown and covered with wrinkles, looked very wise, very ugly, and very kind. His voice was grave and his eyes were merry so that, until you got to now him really well, it was hard to know when he was joking and when he was serious. His name was Doctor Cornelius.”

“Remember that there are only three kinds of things anyone need ever do. (1) Things we ought to do (2) Things we've got to do (3) Things we like doing. I say this because some people seem to spend so much of their time doing things for none of these three reasons, things like reading books they don't like because other people read them.”

“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.”

“The man is a humbug — a vulgar, shallow, self-satisfied mind, absolutely inaccessible to the complexities and delicacies of the real world. He has the journalist's air of being a specialist in everything, of taking in all points of view and being always on the side of the angels: Walter Helwich merely annoys a reader who has the least experience of knowing things, of what knowing is like. There is not two pence worth of real thought or real nobility in him. But he isn't dull…”

“Don't shine so others can see you. Shine so that through you, others can see Him.”

“I am struck here by the curious mixture of justice and injustice in our lives. We are blamed for our real faults but usually not on the right occasions.”

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

“Has this world been so kind to you that you should leave with regret? There are better things ahead than any we leave behind.”

“The quest of the Inner Ring will break your hearts unless you break it. But if you break it, a surprising result will follow. If in your working hours you make the work your end, you will presently find yourself all unawares inside the only circle in your profession that really matters. You will be one of the sound craftsmen, and other sound craftsmen will know it. This group of craftsmen will by no means coincide with the Inner Ring or the Important People or the People in the Know. It will not shape that professional policy or work up that professional influence which fights for the profession as a whole against the public: nor will it lead to those periodic scandals and crises which the Inner Ring produces. But it will do those things which that profession exists to do and will in the long run be responsible for all the respect which that profession in fact enjoys and which the speeches and advertisements cannot maintain. And if in your spare time you consort simply with the people you like, you will again find that you have come unawares to a real inside: that you are indeed snug and safe at the center of something which, seen from without, would look exactly like an Inner Ring. But the difference is that its secrecy is accidental, and its exclusiveness a by-product, and no one was led thither by the lure of the esoteric: for it is only four or five people who like one another meeting to do things that they like. This is friendship. Aristotle placed it among the virtues. It causes perhaps half of all the happiness in the world, and no Inner Ring can ever have it.”
