“The Moral Law isn't any one instinct or any set of instincts: it is something which makes a kind of tune (the tune we call goodness or right conduct) by directing the instincts. (...) The most dangerous thing you can do is to take any one impulse of your own nature and set it up as the thing you ought to follow at all costs. There's not one of them which won't make us into devils if we set it up as an absolute guide. You might think love of humanity in general was safe, but it isn't. If you leave out justice you'll find yourself breaking agreements and faking evidence in trials 'for the sake of humanity,' and become in the end a cruel and treacherous man.”

“If you live for the next world, you get this one in the deal; but if you live only for this world, you lose them both.”

“When you and I met, the meeting was over very shortly, it was nothing. Now it is growing something as we remember it, what will it be when I remember it as I lie down to die, what it makes in me all my days till then - that is the real meeting. The other is only the beginning of it. You say you have poets in your world. Do they not teach you this?”

“I have at last come to the end of the Faerie Queene: and though I say "at last", I almost wish he had lived to write six books more as he had hoped to do — so much have I enjoyed it.”

“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.”

“You can do more with a castle in a story than with the best cardboard castle that ever stood on a nursery table.”

“Now sir, said the bulldog in his business-like way. 'Are you a animal, vegetable, or mineral?'

“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?”

“A Centaur has a man-stomach and a horse-stomach. And of course both want breakfast. So first of all he has porridge and pavenders and kidneys and bacon and omlette and cold ham and toast and marmalade and coffee and beer. And after that he tends to the horse part of himself by grazing for an hour or so and finishing up with a hot mash, some oats, and a bag of sugar. That's why it's such a serious thing to ask a Centaur to stay for the weeekend. A very serious thing indeed.”

“It is a good rule after reading a new book, never to allow yourself another new one till you have read an old one in between.”

“All your life an unattainable ecstasy has hovered just beyond the grasp of your consciousness. The day is coming when you will wake to find, beyond all hope, that you have attained it, or else, that it was within your reach and you have lost it forever.”

“He does not despise real woods because he has read of enchanted woods; the reading makes all real woods a little enchanted.”

“You never know how much you really believe anything until its truth of falsehood becomes a matter of life and death to you. It is easy to say you believe a rope to be strong and sound as long as you are merely using it to cord a box. But suppose you had to hang by that rope over a precipice. Wouldn't you then first discover how much you really trusted it?”

“He liked books if they were books of information and had pictures of grain elevators or of fat foreign children doing exercises in model schools.”

“Lead us not into temptation' often means, among other things, 'Deny me those gratifying invitations, those highly interesting contacts, that participation in the brilliant movements of our age, which I so often, at such risk, desire.' Reflections on the Psalms, ch 7”
