“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?”

“Every joy is beyond all others.”

“And there, right in the middle of it, I find 'Forgive us our sins as we forgive those that sin against us.' There is no slightest suggestion that we are offered forgiveness on any other terms. It is made perfectly clear that if we do not forgive we shall not be forgiven.”

“I think all Christians would agree with me if I said that though Christianity seems at first to be all about morality, all about duties and rules and guilt and virtue, yet it leads you on, out of all that, into something beyond. One has a glimpse of a country where they do not talk of those things, except perhaps as a joke. Everyone there is filled full with what we should call goodness as a mirror is filled with light. But they do not call it goodness. They do not call it anything. They are not thinking of it. They are too busy looking at the source from which it comes. But this is near the stage where the road passes over the rim of our world. No one's eyes can see very far beyond that: lots of people's eyes can see further than mine.” 

“I am trying here to prevent anyone saying the really foolish thing that people often say about Him: I’m ready to accept Jesus as a great moral teacher, but I don’t accept his claim to be God. That is the one thing we must not say. A man who was merely a man and said the sort of things Jesus said would not be a great moral teacher. He would either be a lunatic — on the level with the man who says he is a poached egg — or else he would be the Devil of Hell. You must make your choice. Either this man was, and is, the Son of God, or else a madman or something worse. You can shut him up for a fool, you can spit at him and kill him as a demon or you can fall at his feet and call him Lord and God, but let us not come with any patronizing nonsense about his being a great human teacher. He has not left that open to us. He did not intend to.”

“Odd, the way the less the Bible is read the more it is translated”

“Joy is not a substitute for sex; sex is very often a substitute for Joy. I sometimes wonder whether all pleasures are not substitutes for Joy.”

“I do not think that all who choose wrong roads perish; but their rescue consists in being put back on the right road.”

“Gone! ...And you and I quite crestfallen.”

“Reality, in fact, is usually something you could not have guessed. That is one of the reasons I believe Christianity. It is a religion you could not have guessed. If it offered us just the kind of universe we had always expected, I should feel we were making it up. But, in fact, it is not the sort of thing anyone would have made up. It has just that queer twist about it that real things have. So let us leave behind all these boys' philosophies--these over simple answers. The problem is not simple and the answer is not going to be simple either.”

“I hope no one who reads this book has been quite as miserable as Susan and Lucy were that night; but if you have been - if you've been up all night and cried till you have no more tears left in you - you will know that there comes in the end a sort of quietness. You feel as if nothing is ever going to happen again.”

“Now is our chance to choose the right side. God is holding back to give us that chance. It won't last forever. We must take it or leave it.

“That will not be the time for choosing: it will be the time when we discover which side we really have chosen, whether we realized it before or not. Now, today, this moment, is out chance to chose the right side. God is holding back to give us that chance. It will not last forever. We must take it or leave it.”

“For every one pupil who needs to be guarded against a weak excess of sensibility there are three who need to be awakened from the slumber of cold vulgarity. The task of the modern educator is not to cut down jungles but to irrigate deserts. The right defence against false sentiments is to inculcate just sentiments. By starving the sensibility of our pupils we only make them easier prey to the propagandist when he comes. For famished nature will be avenged and a hard heart is no infallible protection against a soft head.”

“I am almost inclined to set it up as a canon that a children's story which is enjoyed only by children is a bad children's story.”
