Ancient rulers, several of whom have already been mentioned.
Then the people used knotted cords.
As a means of intercommunication. The details of the system have not, however, come down to us.
They were contented with what food and raiment they could get. They lived simple and peaceful lives. Neighbouring districts were within sight, and the cocks and dogs of one could be heard in the other, yet the people grew old and died without ever interchanging visits.
In those days, government was indeed perfect. But nowadays any one can excite the people by saying, "In such and such a place there is a Sage."
Immediately they put together a few provisions and hurry off, neglecting their parents at home and their master's business abroad, filing in unbroken line through territories of Princes, with a string of carts and carriages a thousand li in length. Such is the evil effect of an exaggerated desire for knowledge among our rulers. And if rulers aim at knowledge and neglect Tao, the empire will be overwhelmed in confusion.
How can it be shown that this is so?—Bows and cross-bows and hand-nets and harpoon-arrows, involve much knowledge in their use; but they carry confusion among the birds of the air. Hooks and bait and nets and traps, involve much knowledge in their use; but they carry confusion among the fishes of the deep. Fences and nets and snares, involve much knowledge in their use; but they carry confusion among the beasts of the field. In the same way the sophistical fallacies of the hard and white and the like and the unlike of schoolmen involve much knowledge of argument; but they overwhelm the world in doubt.
Therefore it is that whenever there is great confusion, love of knowledge is ever at the bottom of it. For all men strive to grasp what they do not know, while none strive to grasp what they already know; and all strive to discredit what they do not excel in, while none strive to discredit what they do excel in. The result is overwhelming confusion.
Thus, above, the splendour of the heavenly bodies is dimmed; below, the energy of land and water is disturbed; while midway the influence of the four seasons is destroyed. There is not one tiny creature which moves on earth or flies in air but becomes other than by nature it should be. So overwhelming is the confusion which desire for knowledge has brought upon the world ever since the time of the Three Dynasties downwards! The simple and the guileless have been set aside; the specious and the false have been exalted. Tranquil inaction has given place to a love of disputation; and by disputation has confusion come upon the world.
