昔者庄周梦为蝴蝶，栩栩然蝴蝶也，自喻适志与，不知周也。俄然觉，则戚戚然周也。不知周之梦为蝴蝶与，蝴蝶之梦为周与？周与蝴蝶则必有分矣。此之谓物 — Zhuangzi

"We cling to our own point of view, as though everything depended on it. Yet our opinions have no permanence; like autumn and winter, they gradually pass away."

"Whether you point to a little stalk or a great pillar, a leper or the beautiful Hsi-shih, things ribald and shady or things grotesque and strange, the Way makes them all into one. Their dividedness is their completeness; their completeness is their impairment. No thing is either complete or impaired, but all are made into one again. Only the man of far-reaching vision knows how to make them into one. So he has no use [for categories], but relegates all to the constant. The constant is the useful; the useful is the passable; the passable is the successful; and with success, all is accomplished. He relies upon this alone, relies upon it and does not know he is doing so. This is called the Way."

"All men know the utility of useful things; but they do not know the utility of futility."

"Great truths do not take hold of the hearts of the masses...And now, as all the world is in error, I, though I know the true path,—how shall I guide? If I know that I cannot succeed and yet try to force success, this would be but another source of error. Better, then, to desist and strive no more. But if I strive not, who will?"

"Chuang Tzŭ was fishing in the Pu when the prince of Chu sent two high officials to ask him to take charge of the administration of the Chu State. Chuang Tzŭ went on fishing, and without turning his head said, "I have heard that in Chu there is a sacred tortoise which has been dead now some three thousand years. And that the prince keeps this tortoise carefully enclosed in a chest on the altar of his ancestral temple. Now would this tortoise rather be dead and have its remains venerated, or be alive and wagging its tail in the mud?" "It would rather be alive," replied the two officials, "and wagging its tail in the mud." "Begone!" cried Chuang Tzŭ. "I too will wag my tail in the mud."

"And so in the days when natural instincts prevailed, men moved quietly and gazed steadily. At that time, there were no roads over mountains, nor boats, nor bridges over water. All things were produced, each for its own proper sphere. Birds and beasts multiplied; trees and shrubs grew up. The former might be led by the hand; you could climb up and peep into the ravens nest. For then man dwelt with birds and beasts, and all creation was one. There were no distinctions of good and bad men. Being all equally without knowledge, their virtue could not go astray. Being all equally without evil desires, they were in a state of natural integrity, the perfection of human existence. But when Sages appeared, tripping people over charity and fettering with duty to ones neighbour, doubt found its way into the world. And then with their gushing over music and fussing over ceremony, the empire became divided against itself. ... Destruction of the natural integrity of things, in order to produce articles of various kinds,—this is the fault of the artisan. Annihilation of Tao in order to practise charity and duty to ones neighbour,—this is the error of the Sage."
