“The only things we can keep are the things we freely give to God. What we try to keep for ourselves is just what we are sure to lose.”

“Telling us to obey instinct is like telling us to obey 'people.' People say different things: so do instincts. Our instincts are at war. If it is held that the instinct for preserving the species should always be obeyed at the expense of other instincts, whence do we derive this rule of precedence? To listen to that instinct speaking in its own case and deciding in its own favour would be rather simple minded. Each instinct, if you listen to it, will claim to be gratified at the expense of all the rest. By the very act of listening to one rather than to others we have already prejudged the case. If we did not bring to the examination of our instincts a knowledge of their comparative dignity we could never learn it from them. And that knowledge cannot itself be instinctive: the judge cannot be one of the parties judged: or, if he is, the decision is worthless and there is no ground for placing preservation of the species above self-preservation or sexual appetite.”

“He's not safe, but he's good (referring to Aslan, the Lion, in The Lion, the Witch and the Wardrobe)”

“It is much easier to pray for a bore than to go visit him.”

“He that but looketh on a plate of ham and eggs to lust after it hath already committed breakfast with it in his heart”

“The very power of [textbook writers] depends on the fact that they are dealing with a boy: a boy who thinks he is ‘doing’ his ‘English prep’ and has no notion that ethics, theology, and politics are all at stake. It is not a theory they put into his mind, but an assumption, which ten years hence, its origin forgotten and its presence unconscious, will condition him to take one side in a controversy which he has never recognized as a controversy at all.”

“I think all Christians would agree with me if I said that though Christianity seems at first to be all about morality, all about duties and rules and guilt and virtue, yet it leads you on, out of all that, into something beyond. One has a glimpse of a country where they do not talk of those things, except perhaps as a joke. Everyone there is filled full with what we should call goodness as a mirror is filled with light. But they do not call it goodness. They do not call it anything. They are not thinking of it. They are too busy looking at the source from which it comes. But this is near the stage where the road passes over the rim of our world. No one's eyes can see very far beyond that: lots of people's eyes can see further than mine.” 

“Satan always sends error into the world in pairs that are opposites. His great hope is that you will get so upset about one of his errors, that you'll react into the opposite one, and he's got you.”

“[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.”

“You do not see as quite as well as you think.”

“For what you see and hear depends a good deal on where you are standing: it also depends on what sort of person you are.”

“[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.”

“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?”

“Cobbles and kettledrums! ...I hope this madness isn't going to end in a moonlit climb and broken necks.”

“Whatever he says, let his inner resolution be not to bear whatever comes to him, but to bear it 'for a reasonable period'--and let the reasonable period be shorter than the trial is likely to last. It need not be much shorter; in attacks on patience, chastity, and fortitude, the fun is to make the man yield just when (had he but known it) relief was almost in sight.”
