“[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.”

“Why would you family think about it?""Oh, my mother's the only one that counts, and she likes you very much from what she's seen of you.""So you had me inspected?""No-dash it all, I seem to be saying all the wrong things today. I was absolutely stunned that first day in court, and I rushed off to my mater, who's an absolute dear, and the kind of person who really understands things, and I said, 'Look here! here's the absolutely one and only woman, and she's being put through a simply ghastly awful business and for God's sake come and hold my hand!' You simply don't know how foul it was.”

“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.”

“[N]othing about a book is so unmistakable and so irreplaceable as the stamp of the cultured mind. I don't care what the story is about or what may be the momentary craze for books that appear to have been hammered out by the village blacksmith in a state of intoxication; the minute you get the easy touch of the real craftsman with centuries of civilisation behind him, you get literature.”

“But suppose one doesn't quite know which one wants to put first. Suppose," said Harriet, falling back on words which were not her own, "suppose one is cursed with both a heart and a brain?""You can usually tell," said Miss de Vine, "by seeing what kind of mistakes you make. I'm quite sure that one never makes fundamental mistakes about the thing one really wants to do. Fundamental mistakes arise out of lack of genuine interest. In my opinion, that is.”

“I imagine you come across a number of people who are disconcerted by the difference between what you do feel and what they fancy you ought to feel. It is fatal to pay the smallest attention to them.”

“The two men sat silent for a little, and then Lord Peter said: "D'you like your job?" The detective considered the question, and replied: "Yes—yes, I do. I know it to be useful, and I am fitted to it. I do it quite well—not with inspiration, perhaps, but sufficiently well to take a pride in it. It is full of variety and it forces one to keep up to the mark and not get slack. And there's a future to it. Yes, I like it. Why?" "Oh, nothing," said Peter. "It's a hobby to me, you see. I took it up when the bottom of things was rather knocked out for me, because it was so damned exciting, and the worst of it is, I enjoy it—up to a point. If it was all on paper I'd enjoy every bit of it. I love the beginning of a job—when one doesn't know any of the people and it's just exciting and amusing. But if it comes to really running down a live person and getting him hanged, or even quodded, poor devil, there don't seem as if there was any excuse for me buttin' in, since I don't have to make my livin' by it. And I feel as if I oughtn't ever to find it amusin'. But I do.”
