“The Olympian vice.--In defiance of that philosopher who as true Englishman tried to give any thinking person's laughter a bad reputation ('Laughter is a nasty infirmity of human nature that any thinking person will endeavour to overcome'---Hobbes), I would actually go as far as to rank philosophers according to the level of their laughter---right up to the ones who are capable of golden laughter. And assuming that gods, too, are able to philosophize, as various of my conclusions force me to believe, then I do not doubt when they do so, they know how to laugh in a new and superhuman fashion---and at the expense of everything serious! Gods like to jeer: it seems that even at religious observances they cannot keep from laughing.”

“I have cried even when the laugh did choke me. But no more think that I am all sorry when I cry, for the laugh he come just the same. Keep it always with you that laughter who knock at your door and say, ‘May I come in?’ is not true laughter. No! He is a king, and he come when and how he like. He ask no person, he choose no time of suitability. He say, ‘I am here.”

“Everything we do means something, Ender realized. Them laughing. Me not laughing. He toyed with the idea of trying to be like the other boys. But he couldn’t think of any jokes, and none of theirs seemed funny. Wherever their laughter came from, Ender couldn’t find such a place in himself.”

“Laughter went on and on, like sunlight and stone, even if the human beings who laughed did not.”

“The sound of laughter is like the vaulted dome of a temple of happiness, "that delectable trance of happiness, that ultimate peak of delight. Laughter of delight, delight of laughter." There is no doubt: this laughter goes "far beyond joking, jeering, and ridicule." The two sisters stretched out on their bed are not laughing at anything concrete, their laughter has no object; it is an expression of being rejoicing at being... and in this ecstatic laughter he loses all memory, all desire, cries out to the immediate present of the world, and needs no other knowledge.”

“Do you think it's funny to be so serious when I'm not even out of high school?' she asked.'I don't see how it could be any other way,' said Lee. 'Laughter comes later, like wisdom teeth, and laughter at yourself comes last of all in a mad race with death, and sometimes it isn't in time.”
