"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 raven's 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 one's 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 one's neighbour,—this is the error of the Sage."
