“In the terms in which you set it, the problem is unanswerable; but in the Kingdom of Heaven, those terms do not apply. You have asked the question in a form that is much too limited; the 'solution' must be brought in from outside your sphere of reference altogether.”

“I have the most ill-regulated memory. It does those things which it ought not to do and leaves undone the things it ought to have done. But it has not yet gone on strike altogether.”

“Why do you want a letter from me? Why don't you take the trouble to find out for yourselves what Christianity is? You take time to learn technical terms about electricity. Why don't you do as much for theology? Why do you never read the great writings on the subject, but take your information from the secular 'experts' who have picked it up as inaccurately as you? Why don't you learn the facts in this field as honestly as your own field? Why do you accept mildewed old heresies as the language of the church, when any handbook on church history will tell you where they came from?Why do you balk at the doctrine of the Trinity - God the three in One - yet meekly acquiesce when Einstein tells you E=mc2? What makes you suppose that the expression "God ordains" is narrow and bigoted, while your own expression, "Science demands" is taken as an objective statement of fact?You would be ashamed to know as little about internal combustion as you know about Christian beliefs.I admit, you can practice Christianity without knowing much theology, just as you can drive a car without knowing much about internal combustion. But when something breaks down in the car, you go humbly to the man who understands the works; whereas if something goes wrong with religion, you merely throw the works away and tell the theologian he is a liar.Why do you want a letter from me telling you about God? You will never bother to check on it or find out whether I'm giving you personal opinions or Christian doctrines. Don't bother. Go away and do some work and let me get on with mine.”

“If God made everything, did He make the Devil?' This is the kind of embarrassing question which any child can ask before breakfast, and for which no neat and handy formula is provided in the Parents' Manual…Later in life, however, the problem of time and the problem of evil become desperately urgent, and it is useless to tell us to run away and play and that we shall understand when we are older. The world has grown hoary, and the questions are still unanswered.”

“[I]t's difficult to make people see that what you have been taught counts for nothing, and that the only things worth having are the things you find out for yourself. Also, that when so many brands of what Chesterton calls 'fancy souls' and theories of life are offered you, there is no sense in not looking pretty carefully to see what you are going in for. [...] It isn't a case of 'Here is the Christian religion, the one authoritative and respectable rule of life. Take it or leave it'. It's 'Here's a muddling kind of affair called Life, and here are nineteen or twenty different explanations of it, all supported by people whose opinions are not to be sneezed at. Among them is the Christian religion in which you happpen to have been brought up. Your friend so-and-so has been brought up in quite a different way of thinking; is a perfectly splendid person and thoroughly happy. What are you going to do about it?' -- I'm worrying it out quietly, and whatever I get hold of will be valuable, because I've got it for myself; but really, you know, the whole question is not as simple as it looks.”

“Wonder whether Mussolini's mother spanked him too much or too little--you never know, these psychological days. Can distinctly remember spanking Peter, but it doesn't seem to have warped him much, so psychologists very likely all wrong.”

“And you, Mary, if you must run off to London, why do it in that unfinished manner, so that I was left without the car, and couldn't catch anything until the midnight train at Northallerton? It's so much better to do things neatly and properly, even stupid things.”
