“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?”

“Stop it," spluttered Eustace, "go away. Put that thing away. It's not safe. Stop it, I say. I'll tell Caspian. I'll have you muzzled and tied up." "Why do you not draw your own sword, poltroon!" cheeped the Mouse. "Draw and fight or I'll beat you black and blue with the flat." "I haven't got one," said Eustace. "I'm a pacifist. I don't believe in fighting." "Do I understand," said Reepicheep, withdrawing his sword for a moment and speaking very sternly, "that you do not intend to give me satisfaction?”

“It is funny how mortals always picture us as putting things into their minds: in reality our best work is done by keeping things out.”

“Try to exclude the possibility of suffering which the order of nature and the existence of free-wills involve, and you find that you have excluded life itself”

“The great thing to remember is that though our feelings come and go God's love for us does not.” 

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

“As Venus within Eros does not really aim at pleasure, so Eros does not aim at happiness. We may think he does, but when he is brought to the test it proves otherwise... For it is the very mark of Eros that when he is in us we had rather share unhappiness with the Beloved than be happy on any other terms.”

“Heaven is reality itself. All that is fully real is Heavenly. For all that can be shaken will be shaken and only the unshakeable remains.”

“And so take away his work, which was his life [. . .] and all his glory and his great deeds? Make a child and a dotard of him? Keep him to myself at that cost? Make him so mine that he was no longer his?”

“...Aslan didn't tell Pole what would happen. He only told her what to do. That fellow will be the death of us once he's up, I shouldn't wonder. But that doesn't let us off following the signs.”

“The real test of being in the presence of God is, that you either forget about yourself altogether or see yourself as a small, dirty object.”

“Make your choice, adventurous Stranger, Strike the bell and bide the danger, Or wonder, till it drives you mad, What would have followed if you had.”

“The worst of sleeping out of doors is that you wake up so dreadfully early. And when you wake up you have to get up because the ground is so hard you are uncomfortable. And it makes matters worse if there is nothing but apples for breakfast and you have had nothing but apples for supper the night before.”

“The value of myth is that it takes all the things you know and restores to them the rich significance which has been hidden by the veil of familiarity.”

“I'm on Aslan's side even if there isn't any Aslan to lead it. I'm going to live as like a Narnian as I can even if there isn't any Narnia.”
