"Tsze-kung said, What I do not wish men to do to me, I also wish not to do to men. The Master said, Tsze, you have not attained to that."
Confucius (551-479 BC), Analects 5:12
"Do not do to others what you would not like yourself. Then there will be no resentment against you, either in the family or in the state."
Confucius [K'ung Fu Tse] (551-479 BC), Analects 12:2
"Tsze-kung said, Suppose the case of a man extensively conferring benefits on the people, and able to assist all, what would you say of him? Might he be called perfectly virtuous? The Master said, Why speak only of virtue in connection with him? Must he not have the qualities of a sage? Even Yao and Shun were still solicitous about this. Now the man of perfect virtue, wishing to be established himself, seeks also to establish others; wishing to be enlarged himself, he seeks also to enlarge others. To be able to judge of others by what is nigh in ourselves;-this may be called the art of virtue."
