Da linguagem e da redefinição...

Confucius believed that social disorder often stemmed from failure to perceive, understand, and deal with reality. Fundamentally, then, social disorder can stem from the failure to call things by their proper names, and his solution to this was Zhèngmíng (Chinese: 正名; pinyin: zhèngmíng; literally "rectification of terms"). He gave an explanation of zhengming to one of his disciples.

Tsze-lu said, "The ruler of Wei has been waiting for you, in order with you to administer the government. What will you consider the first thing to be done?"
The Master replied, "What is necessary is to rectify names."
"So! indeed!" said Tsze-lu. "You are wide of the mark! Why must there be such rectification?"
The Master said, "How uncultivated you are, Yu! A superior man, in regard to what he does not know, shows a cautious reserve.

• If names be not correct, language is not in accordance with the truth of things.
• If language be not in accordance with the truth of things, affairs cannot be carried on to success.
• When affairs cannot be carried on to success, proprieties and music do not flourish.
• When proprieties and music do not flourish, punishments will not be properly awarded.
• When punishments are not properly awarded, the people do not know how to move hand or foot.

Therefore a superior man considers it necessary that the names he uses may be spoken appropriately, and also that what he speaks may be carried out appropriately. What the superior man requires is just that in his words there may be nothing incorrect."
(Analects XIII, 3, tr. Legge)

Xun Zi chapter (22) "On the Rectification of Names" claims the ancient sage kings chose names (Chinese: 名; pinyin: míng) that directly corresponded with actualities (Chinese: 實; pinyin: shí), but later generations confused terminology, coined new nomenclature, and thus could no longer distinguish right from wrong.
