Chapter 7, Part 10 - Lieh Tzu

In the east of China there was a man named Yüan Ching Mu, who set off on a journey but was overcome by hunger on the way. A certain robber from Hu-fu, of the name of Ch'iu, saw him lying there, and fetched a bowl of rice-gruel in order to feed him. After swallowing three mouthfuls, Yüan Ching Mu opened his eyes and murmured, 'Who are you?' 'I am a native of Hu-fu, and my name is Ch'iu.' 'Oh misery!' cried Yüan Ching Mu, 'are not you the robber Ch'iu? What are you feeding me for? I am an honest man and cannot eat your food.'

So saying, he clutched the ground with both hands, and began retching and coughing in order to bring it up again. Not succeeding, however, he fell flat on his face and expired.

Now the man from Hu-fu was a robber, no doubt, but the food he brought was not affected thereby. Because a man is a robber, to refuse to eat the food he offers you, on the ground that it is tainted with crime, is to have lost all power of discriminating between the normal and the real.
