“Avoid doing what you would blame others for doing.” – Thales
“What you do not want to happen to you, do not do it yourself either. “ – Sextus the Pythagorean. The oldest extant reference to Sextus is by Origin in the third century of the common era.
“Do not do to others what would anger you if done to you by others.” – Isocrates
“What thou avoidest suffering thyself seek not to impose on others.” – Epictetus
“It is impossible to live a pleasant life without living wisely and well and justly (agreeing ‘neither to harm nor be harmed’), and it is impossible to live wisely and well and justly without living a pleasant life.” – Epicurus
“…it has been shown that to injure anyone is never just anywhere.” – Socrates, in Plato’s Republic. Plato is the first person known to have said this.
“Zi Gong asked, saying, “Is there one word that may serve as a rule of practice for all one’s life?” The Master said, “Is not RECIPROCITY such a word?” – Confucius
“Never impose on others what you would not choose for yourself.” – Confucius
“If people regarded other people’s families in the same way that they regard their own, who then would incite their own family to attack that of another? For one would do for others as one would do for oneself.” – Mozi
“The sage has no interest of his own, but takes the interests of the people as his own. He is kind to the kind; he is also kind to the unkind: for Virtue is kind. He is faithful to the faithful; he is also faithful to the unfaithful: for Virtue is faithful.” –Laozi
“Regard your neighbor’s gain as your own gain, and your neighbor’s loss as your own loss.” –Laozi
