“My idea of God is not a divine idea. It has to be shattered time after time. He shatters it Himself.”

“The promise, made when I am in love and because I am in love, to be true to the beloved as long as I live, commits me to being true even if I cease to be in love. A promise must be about things that I can do, about actions: no one can promise to go on feeling in a certain way. He might as well promise to never have a headache or always to feel hungry.” 

“The Friendship is not a reward for our discrimination and good taste in finding one another out. IT is the instrument by which God reveals to each the beauties of all the others. They are no greater than the beauties of a thousand other men; by Friendship God opens our eyes to them. They are, like all beauties, derived from Him, and then, in a good Friendship, increased by Him through the Friendship itself, so that it is His instrument for creating as well as for revealing. At this feast it is he who has spread the board and it is He who has chosen the guests. It is He, we may dare to hope, who sometimes does, and always should, preside. Let us not reckon without our Host.”

“Because, as we know, almost anything can be read into any book if you are determined enough. This will be especially impressed on anyone who has written fantastic fiction. He will find reviewers, both favourable and hostile, reading into his stories all manner of allegorical meanings which he never intended. (Some of the allegories thus imposed on my own books have been so ingenious and interesting that I often wish I had thought of them myself.)”

“Friendship, then, like the other natural loves, is unable to save itself. In reality, because it is spiritual and therefore faces a subtler enemy, it must, even more wholeheartedly than they, invoke the divine protection if it hopes to remain sweet. For consider how narrow its true path is. Is must not become what the people call a "mutual admiration society"; yet if it is not full of mutual admiration, of Appreciative love, it is not Friendship at all.”

“If my house has collapsed at one blow, that is because it was a house of cards. The faith which 'took these things into account' was not faith but imagination.”

“And the Prince stared at her like a man out of his wits.” 

“Life is too deep for words, so don't try to describe it, just live it. Actually this quote doesn't sound like C.S. Lewis at all. Can anyone provide a source?”

“Peter did not feel very brave; indeed, he felt he was going to be sick. But that made no difference to what he had to do.”

“There is nothing indulgent about the Moral Law. It is as hard as nails. It tells you to do the straight thing and it does not seem to care how painful, or dangerous, or difficult it is to do.”

“There are a dozen views about everything until you know the answer. Then there's never more than one.”

“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?”

“The real trouble is that 'kindness' is a quality fatally easy to attribute to ourselves on quite inadequate grounds. Everyone feels benevolent if nothing happens to be annoying him at the moment. Thus a man easily comes to console himself for all his other vices by a conviction that 'his heart's in the right place' and 'he wouldn't hurt a fly,' though in fact he has never made the slightest sacrifice for a fellow creature. We think we are kind when we are only happy: it is not so easy, on the same grounds, to imagine oneself temperate, chaste, or humble.”

“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”

“We use a most unfortunate idiom when we say, of a lustful man prowling the streets, that he "wants a woman". Strictly speaking, a woman is just what he does not want. He wants a pleasure for which a woman happens to be the necessary piece of apparatus. How much he cares about the woman as such may be gauged by his attitude for her five minutes after fruition.”
