“You would not have called to me unless I had been calling to you," said the Lion.”

“And grief still feels like fear. Perhaps, more strictly, like suspense. Or like waiting; just hanging about waiting for something to happen. It gives life a permanently provisional feeling. It doesn't seem worth starting anything. I can't settle down. I yawn, fidget, I smoke too much. Up till this I always had too little time. Now there is nothing but time. Almost pure time, empty successiveness.”

“By the way, don't 'weep inwardly' and get a sore throat. If you must weep, weep: a good honest howl! I suspect we - and especially, my sex - don't cry enough now-a-days. Aeneas and Hector and Beowulf, Roland and Lancelot blubbered like schoolgirls, so why shouldn't we?”

“How monotonously alike all the great tyrants and conquerors have been; how gloriously different are the saints.”

“...here also forgiving does not mean excusing. Many people seem to think it does. They think that if you ask them to forgive someone who has cheated or bullied them you are trying to make out that there was really no cheating or bullying. But if that were so, there would be nothing to forgive. (This doesn't mean that you must necessarily believe his next promise. It does mean that you must make every effort to kill every taste of resentment in your own heart - every wish to humiliate or hurt him or to pay him out.)”

“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.”

“[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.”

“If they are wrong they need your prayers all the more; and if they are your enemies, then you are under orders to pray for them. That is one of the rules common to the whole house.” 

“It is no disparagement to the garden to say it will not fence and weed itself, nor prune its own fruit trees, nor roll and cut its own lawns...It will remain a garden only if someone does all these things to it...If you want to see the difference between [the garden's] contribution and the gardener's, put the commonest weed it grows side by side with his hoes rakes, shears, and a packet of weed killer; you have put beauty, energy, and fecundity beside dead, steril things. Just so, our 'decency and common sense' show grey and deathlike beside the geniality of love.”

“If I discover within myself a desire which no experience in this world can satisfy, the most probable explanation is that I was made for another world.”

“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?”

“In those days a boy on the classical side officially did almost nothing but classics. I think this was wise; the greatest service we can to education today is to teach few subjects. No one has time to do more than a very few things well before he is twenty, and when we force a boy to be a mediocrity in a dozen subjects we destroy his standards, perhaps for life.”

“Friendship is unnecessary, like philosophy, like art.... It has no survival value; rather it is one of those things which give value to survival.”

“…the greatest service we can do to education today is to teach fewer subjects. No one has time to do more than a very few things well before he is twenty, and when we force a boy to be a mediocrity in a dozen subjects, we destroy his standards, perhaps for life.” 

“You can be good for the mere sake of goodness; you cannot be bad for the mere sake of badness. You can do a kind action when you are not feeling kind and when it gives you no pleasure, simply because kindness is right; but no one ever did a cruel action simply because cruelty is wrong - only because cruelty is pleasant or useful to him, In other words, badness cannot succeed even in being bad in the same way in which goodness is good. Goodness is, so to speak, itself: badness is only spoiled goodness. And there must be something good first before it can be spoiled.”
