“You never know how much you really believe anything until its truth of falsehood becomes a matter of life and death to you. It is easy to say you believe a rope to be strong and sound as long as you are merely using it to cord a box. But suppose you had to hang by that rope over a precipice. Wouldn't you then first discover how much you really trusted it?”

“We may give our human loves the unconditional allegiance which we owe only to God. They they become gods: then they become demons. Then they will destroy us, and also destroy themselves. For natural loves that are allowed to become gods do not remain loves. They are still called so, but can become in fact complicated forms of hatred.”

“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.”

“In friendship...we think we have chosen our peers. In reality a few years' difference in the dates of our births, a few more miles between certain houses, the choice of one university instead of another...the accident of a topic being raised or not raised at a first meeting--any of these chances might have kept us apart. But, for a Christian, there are, strictly speaking no chances. A secret master of ceremonies has been at work. Christ, who said to the disciples, "Ye have not chosen me, but I have chosen you," can truly say to every group of Christian friends, "Ye have not chosen one another but I have chosen you for one another." The friendship is not a reward for our discriminating and good taste in finding one another out. It is the instrument by which God reveals to each of us the beauties of others.” 

“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?”

“Lightly men talk of saying what they mean. Often when he was teaching me to write in Greek the Fox would say, “Child, to say the very thing you really mean, the whole of it, nothing more or less or other than what you really mean; that’s the whole art and joy of words.” A glib saying. When the time comes to you at which you will be forced at last to utter the speech which has lain at the centre of your soul for years, which you have, all that time, idiot-like, been saying over and over, you’ll not talk about joy of words.”

“No man knows how bad he is till he has tried very hard to be good.”

“It may well be that by trickery of priests men have sometimes taken a mortal's voice for a god's. But it will not work the other way. No one who hears a god's voice takes it for a man's.”

“Do not be deceived, Wormwood. Our cause is never more in danger than when a human, no longer desiring, but still intending, to do our Enemy's will, looks round upon a universe from which every trace of Him seems to have vanished, and asks why he has been forsaken, and still obeys.”

“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.”

“Prostitutes are in no danger of finding their present life so satisfactory that they cannot turn to God: the proud, the avaricious, the self-righteous, are in that danger.”

“We may be sure that the characteristic blindness of the twentieth century - the blindness about which posterity will ask, "But how could they have thought that?" - lies where we have never suspected it... None of us can fully escape this blindness, but we shall certainly increase it, and weaken our guard against it, if we read only modern books. Where they are true they will give us truths which we half knew already. Where they are false they will aggravate the error with which we are already dangerously ill. The only palliative is to keep the clean sea breeze of the centuries blowing through our minds, and this can be done only by reading old books.”

“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.”

“if anyone present wishes to make me the subject of his wit, I am very much at his service--with my sword--whenever he has leisure.”

“In reading Chesterton, as in reading MacDonald, I did not know what I was letting myself in for. A young man who wishes to remain a sound Atheist cannot be too careful of his reading. There are traps everywhere — "Bibles laid open, millions of surprises," as Herbert says, "fine nets and stratagems." God is, if I may say it, very unscrupulous.”
