“If the solar system was brought about by an accidental collision, then the appearance of organic life on this planet was also an accident, and the whole evolution of Man was an accident too. If so, then all our present thoughts are mere accidents--the accidental by-product of the movement of atoms. And this holds for the thoughts of the materialists and astronomers as well as for anyone else's. But if their thoughts--i.e. of materialism and astronomy--are merely accidental by-products, why should we believe them to be true? I see no reason for believing that one accident should be able to give me a correct account of all the other accidents. It's like expecting that the accidental shape taken by the splash when you upset a milkjug should give you a correct account of how the jug was made and why it was upset.”

“If we consider the unblushing promises of reward … promised in the Gospels, it would seem that our Lord finds our desires not too strong, but too weak. We are half-hearted creatures, fooling about with drink and sex and ambition when infinite joy is offered us, like an ignorant child who wants to go on making mud pies in a slum because he cannot imagine what is meant by the offer of a holiday at sea. We are far too easily pleased.”

“No man can be an exile if he remembers that all the world is one city.”

“There is nothing like suspense and anxiety for barricading a human's mind against the Enemy. He wants men to be concerned with what they do; our business is to keep them thinking about what will happen to them.”

“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.”

“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?”

“On the rebound one passes into tears and pathos. Maudlin tears. I almost prefer the moments of agony. These are at least clean and honest. But the bath of self-pity, the wallow, the loathsome sticky-sweet pleasure of indulging it--that disgusts me”

“Music. A meaningless acceleration in the rhythm of celestial experience.”

“Die before you die, there is no chance after.”

“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.”

“I write for the unlearned about things in which I am unlearned myself.”

“It is, of course, quite true that God will not love you any less, or have less use for you, if you happen to have been born with a very second-rate brain.”

“Those of us who are blamed when old for reading childish books were blamed when children for reading books too old for us.”

“You are never too old to set another goal, or to dream a new dream.”

“People who have not been in Narnia sometimes think that a thing cannot be good and terrible at the same time.”
