Chapter 29, Part 2C - Chuang Tzu

Man Kou-te said, "The petty thief is imprisoned but the big thief becomes a feudal lord, and we all know that righteous gentlemen are to be found at the gates of the feudal lords. In ancient times, Hsiao-po, Duke Huan of Ch'i, murdered his elder brother and took his sister-in-law for a wife, and yet Kuan Chung was willing to become his minister. Ch'ang, Viscount T'ien Ch'eng, murdered his sovereign and stole his state, and yet Confucius was willing to receive gifts from him.

"In pronouncement they condemned them, but in practice they bowed before them. Think how this contradiction between the facts of word and deed must have troubled their breasts! Could the two help but clash? So the book says, Who is bad? Who is good? The successful man becomes the head, the unsuccessful man becomes the tail."

"But," said Tzu-chang, "if you take no thought for conduct, then there cease to be any ethical ties between near and distant kin, any fitting distinctions between noble and humble, any proper order between elder and younger. How is one to maintain the distinctions decreed by the five moral principles and the six social relationships?"
