"I am good to the man who is good to me, likewise, I am also good to the bad man."
Tao Te Ching
"The sage has no interest of his own, but regards 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."
Tao Te Ching, Chapter 49 (~500 BC)
"Pity the misfortunes of others; rejoice in the well-being of others; help those who are in want; save men in danger; rejoice at the success of others; and sympathise with their reverses, even as though you were in their place."
