“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?”

“All get what they want; they do not always like it.”

“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.” 

“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 false religion of lust is baser than the false religion of mother-love or patriotism or art: but lust is less likely to be made into a religion.”

“Poetry most often communicates emotions, not directly, but by creating imaginatively the grounds for those emotions. It therefore communicates something more than the emotion; only by means of that something more does it communicate the emotion at all.”

“Do not waste time bothering whether you ‘love’ your neighbor; act as if you did. As soon as we do this we find one of the great secrets. When you are behaving as if you loved someone, you will presently come to love him.”

“God will invade. But I wonder whether people who ask God to interfere openly and directly in our world quite realise what it will be like when He does. When that happens, it is the end of the world. When the author walks on to the stage the play is over. God is going to invade, all right: but what is the good of saying you are on His side then, when you see the whole natural universe melting away like a dream and something else - something it never entered your head to conceive - comes crashing in; something so beautiful to some of us and so terrible to others that none of us will have any choice left? For this time it will God without disguise; something so overwhelming that it will strike either irresistible love or irresistible horror into every creature. It will be too late then to choose your side. There is no use saying you choose to lie down when it has become impossible to stand up. That will not be the time for choosing; it will be the time when we discover which side we really have chosen, whether we realised it before or not. Now, today, this moment, is our chance to choose the right side. God is holding back to give us that chance. It will not last for ever. We must take it or leave it.”

“And above all, you must be asking which door is the true one; not which pleases you best by its paint and panelling…the question should never be: ‘Do I like that kind of service?’ but ‘Are these doctrines true: Is holiness there? Does my conscience move me towards this? Is my reluctance to move to this door due to my pride, or my mere taste, or my personal dislike for this particular door-keeper?”

“Why you fool, it's the educated reader who CAN be gulled. All our difficulty comes with the others. When did you meet a workman who believes the papers? He takes it for granted that they're all propaganda and skips the leading articles. He buys his paper for the football results and the little paragraphs about girls falling out of windows and corpses found in Mayfair flats. He is our problem. We have to recondition him. But the educated public, the people who read the high-brow weeklies, don't need reconditioning. They're all right already. They'll believe anything.”

“Remember He is the artist and you are only the picture. You can't see it. So quietly submit to be painted---i.e., keep fulfilling all the obvious duties of your station (you really know quite well enough what they are!), asking forgiveness for each failure and then leaving it alone.You are in the right way. Walk---don't keep on looking at it.”

“Don't be scared by the word authority. Believing things on authority only means believing them because you've been told them by someone you think trustworthy. Ninety-nine per cent of the things you believe are believed on authority. I believe there is such a place as New York. I haven't seen it myself. I couldn't prove by abstract reasoning that there must be such a place. I believe it because reliable people have told me so. The ordinary man believes in the Solar System, atoms, evolution, and the circulation of the blood on authority -because the scientists say so. Every historical statement in the world is believed on authority. None of us has seen the Norman Conquest or the defeat of the Armada. None of us could prove them by pure logic as you prove a thing in mathematics. We believe them simply because people who did see them have left writings that tell us about them: in fact, on authority. A man who jibbed at authority in other things as some people do in religion would have to be content to know nothing all his life.”

“But how can the characters in a play guess the plot? We are not the playwright, we are not the producer, we are not even the audience. We are on the stage. To play well the scenes in which we are "on" concerns us much more than to guess about the scenes that follow it.”

“They call him Aslan in That Place," said Eustace. "What a curious name!" "Not half so curious as himself," said Eustace solemnly.”

“When I'm older I'll understand" said Lucy, " I am older and I don't think I want to understand", replied Edmund”
