“and so, if you wish to glimpse inside a human soul and get to know a man, don't bother analyzing his ways of being silent, of talking, of weeping, or seeing how much he is moved by noble ideas; you'll get better results if you just watch him laugh. If he laughs well, he's a good man. You must, however, note all the shades of his laugh.”

“Some sleepers have intelligent faces even in sleep, while other faces, even intelligent ones, become very stupid in sleep and therefore ridiculous. I don't know what makes that happen; I only want to say that a laughing man, like a sleeping one, most often knows nothing about his face. A great many people don't know how to laugh at all. However, there's nothing to know here: it's a gift, and it can't be fabricated. It can only be fabricated by re-educating oneself, developing oneself for the better, and overcoming the bad instincts of one's character; then the laughter of such a person might quite possibly change for the better. A man can give himself away completely by his laughter, so that you suddenly learn all of his innermost secrets. Even indisputably intelligent laughter is sometimes repulsive. Laughter calls first of all for sincerity, and where does one find sincerity? Laughter calls for lack of spite, but people most often laugh spitefully. Sincere and unspiteful laughter is mirth. A man's mirth is a feature that gives away the whole man, from head to foot. Someone's character won't be cracked for a long time, then the man bursts out laughing somehow quite sincerely, and his whole character suddenly opens up as if on the flat of your hand. Only a man of the loftiest and happiest development knows how to be mirthful infectiously, that is, irresistibly and goodheartedly. I'm not speaking of his mental development, but of his character, of the whole man. And so, if you want to discern a man and know his soul, you must look, not at how he keeps silent, or how he speaks, or how he weeps, or even how he is stirred by the noblest ideas, but you had better look at him when he laughs. If a man has a good laugh, it means he's a good man. Note at the same time all the nuances: for instance, a man's laughter must in no case seem stupid to you, however merry and simplehearted it may be. The moment you notice the slightest trace of stupidity in someone's laughter, it undoubtedly means that the man is of limited intelligence, though he may do nothing but pour out ideas. Or if his laughter isn't stupid, but the man himself, when he laughs, for some reason suddenly seems ridiculous to you, even just slightly—know, then, that the man has no real sense of dignity, not fully in any case. Or finally, if his laughter is infectious, but for some reason still seems banal to you, know, then, that the man's nature is on the banal side as well, and all the noble and lofty that you noticed in him before is either deliberately affected or unconsciously borrowed, and later on the man is certain to change for the worse, to take up what's 'useful' and throw his noble ideas away without regret, as the errors and infatuations of youth.”

“I know what you must think of me,' [the Doctor] said, his voice so slow. It was like a voice designed for laughing that didn't get to do it often. 'I'm going to tell you a story about a man who travels, and everywhere he goes, he makes everyone's lives better. I'm not that man. That man doesn't exist. I wish he did.' He smiled. 'I'd believe in him.”

“He shook his head and gave this laugh, a good laugh, and just looked at me. "You always this happy?""No," I said, laughing. "It's you. Every time I see you, I just...I don't know. You make me smile.”

“Did you bite someone?' Jack enquired.'I laughed at people, which is much worse. My laughter has sharper teeth than any dog. It tears people apart who wish to be taken seriously, but I could not help myself. There were many complaints and finally a man in a brown suit came and looked at me. He was very important and not used to being laughed at, but I could see he had dandruff on his collar, and there was a spot of his breakfast egg on his lapel. You should have seen him - so puffed up and proud of himself. I couldn't help but laugh and that made people see him as I did, and so they laughed too. All of a sudden everyone realised that for all his status in official matters, he was a man who lived alone and was loveless.”
