The Keeper of Animals under King Hsüan, of the Chou dynasty, had an assistant named Liang Yang, who was skilled in the management of wild birds and beasts. When he fed them in their park-enclosure, all the animals showed themselves tame and tractable, although they comprised tigers, wolves, eagles and ospreys. Male and female freely propagated their kind, and their numbers multiplied.
The different species lived promiscuously together, yet they never clawed nor bit one another.
The King was afraid lest this man’s secret should die with him, and commanded him to impart it to the Keeper. So Liang Yang appeared before the Keeper and said: ‘I am only a humble servant, and have really nothing to impart. I fear his Majesty thinks I am hiding something from you. With regard to my method of feeding tigers, all I have to say is this: when yielded to, they are pleased; when opposed, they are angry. Such is the natural disposition of all living creatures. But neither their pleasure nor their anger is manifested without a cause. Both are really excited by opposition.
‘In feeding tigers, then, I avoid giving them either live animals or whole carcases, lest in the former case the act of killing, in the latter the act of tearing them to pieces, should excite them to fury. Again, I time their periods of hunger and repletion, and I gain a full understanding of the causes of their anger. Tigers are of a different species from man, but, like him, they respond to those who coax them with food, and consequently the act of killing their victims tends to provoke them. This being so, I should not think of opposing them and thus provoking their anger; neither do I humour them and thus cause them to feel pleased. For this feeling of pleasure will in time be succeeded by anger, just as anger must invariably be succeeded by pleasure. Neither of these states hits the proper mean. Hence it is my aim to be neither antagonistic nor compliant, so that the animals regard me as one of themselves. Thus it happens that they walk about the park without regretting the tall forests and the broad marshes, and rest in the enclosure without yearning for the lonely mountains and the dark valleys. Such are the principles which have led to the results you see.’
