"A person who does not read cannot think. He may have good mental processes, but he has nothing to think about. You can feel for people or natural phenomena and react to them, but they are not ideas. You cannot think about them."

"The only difference between me and most people is that I'm perfectly aware that all my important decisions are made for me by my subconscious. My frontal lobes are just kidding themselves that they decide anything at all. All they do is think up reasons for the decisions that are already made."

"Every book takes me from 35 to 41 days to write. I don't know why that is. I've tried to get it down to 30 or 31, depending on the length of the month, but it won't work. I don't drink while I'm writing because it fuddles my logical processes, but when I finish a book I go down to the kitchen and pour myself a big belt."

"What do I believe in? Belief means faith, and there's only one damn thing in the world I have any faith in. That's the idea of American democracy, because it seems to me so obvious that that's the only sensible way to run human affairs."

"Of course the modern detective story puts off its best tricks till the last, but Doyle always put his best tricks first and that's why they're still the best ones."

"I think the detective story is by far the best upholder of the democratic doctrine in literature. I mean, there couldn't have been detective stories until there were democracies, because the very foundation of the detective story is the thesis that if you're guilty you'll get it in the neck and if you're innocent you can't possibly be harmed. No matter who you are. There was no such conception of justice until after 1830. There was no such thing as a policeman or a detective in the world before 1830, because the modern conception of the policeman and detective, namely, a man whose only function is to find out who did it and then get the evidence that will punish him, did not exist. ... In Paris before the year 1800 – read the Dumas stories – there were gangs of people whose business was to go out and punish wrongdoers. But why? Because they had hurt De Marillac or Richelieu or the Duke or some Huguenot noble, not just because they had harmed society. It is only the modern policeman that is out to protect society."

"It is impossible for any Sherlock Holmes story not to have at least one marvelous scene."

"The incredible thing happens at the beginning of the story always, you notice, not the end. A Sherlock Holmes story is never a trick story."

"I really mean what I say. A Dickens character to me is a theatrical projection of a character. Not that it isn't real. It's real, but in that removed sense. But Sherlock Holmes is simply there. I would be astonished if I went to 221½ B Baker Street and didn't find him."

"Bosh. I find a rival – but no, I won't flatter myself that Tecumseh Fox would consider himself a rival of Dol Bonner – I find an eminent detective in your apartment, and that alone is enough, without adding that he is concealed in your bedroom while I am discussing my business with you..."

"Mathewson pitched against Cincinnati yesterday. Another way of putting it is that Cincinnati lost a game of baseball. The first statement means the same as the second."

"Under no circumstances does he get good natured until noon. If he has to get up early in the morning you have to converse with him in signs most of the day because he pants so hard that his mouth cannot open in conversation. He is a lovely travelling companion, if he happens to be in the next coach."

"You felt he was laughing at the world, not with it."

"I long ago come to the conclusion that all life is six to five against. (A Nice Price)"

"Some day, somewhere … a guy is going to come to you and show you a nice brand-new deck of cards on which the seal is never broken, and this guy is going to offer to bet you that the jack of spades will jump out of this deck and squirt cider in your ear. But, son … do not bet him, for as sure as you do you are going to get an ear full of cider. (From the short story The Idyll of Miss Sarah Brown, Collier's Weekly, January 28, 1933. Used with slightly different wording in the musical Guys and Dolls -- both the 1950 stage and the 1955 film versions.)"

"Always try to rub against money, for if you rub against money long enough, some of it may rub off on you. (A Very Honorable Guy)"
