“Those who are enjoying something, or suffering something, together, are companions. Those who enjoy or suffer one another, are not.”

“Holy places are dark places. It is life and strength, not knowledge and words, that we get in them. Holy wisdom is not clear and thin like water, but thick and dark like blood.”

“In those days Mr. Sherlock Holmes was still living in Baker Street and the Bastables were looking for treasure in the Lewisham Road.”

“Gone! And you and I quite crestfallen. It’s always like that, you can’t keep him; it’s not as if he were a tame lion.”

“The world does not need more Christian literature. What it needs is more Christians writing good literature.”

“The only people who achieve much are those who want knowledge so badly that they seek it while the conditions are still unfavourable. Favourable conditions never come.”

“Love is not affectionate feeling, but a steady wish for the loved person's ultimate good as far as it can be obtained.”

“The change which the writing wrought in me (and of which I did not write) was only a beginning; only to prepare me for the gods' surgery. They used my own pen to probe my wound. ”

“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.”

“I have no duty to be anyone's Friend and no man in the world has a duty to be mine. No claims, no shadow of necessity. Friendship is unnecessary, like philosophy, like art, like the universe itself (for God did not need to create). It has no survival value; rather it is one of those things which give value to survival.”

“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?”

“To walk out of His will is to walk into nowhere.”

“You must ask for God's help. Even when you have done so, it may seem to you for a long time that no help, or less help than you need, is being given. Never mind. After each failure, ask forgiveness, pick yourself up, and try again. Very often what God first helps us towards is not the virtue itself but just this power of always trying again.”

“Satan always sends error into the world in pairs that are opposites. His great hope is that you will get so upset about one of his errors, that you'll react into the opposite one, and he's got you.”

“No man knows how bad he is till he has tried very hard to be good. A silly idea is current that good people do not know what temptation means. This is an obvious lie. Only those who try to resist temptation know how strong it is. After all, you find out the strength of the German army by fighting against it, not by giving in. You find out the strength of a wind by trying to walk against it, not by lying down. A man who gives in to temptation after five minutes simply does not know what it would have been like an hour later. That is why bad people, in one sense, know very little about badness — they have lived a sheltered life by always giving in. We never find out the strength of the evil impulse inside us until we try to fight it: and Christ, because He was the only man who never yielded to temptation, is also the only man who knows to the full what temptation means — the only complete realist.”
