The so-called golden rule, that is, behave toward others as you would have them behave toward you; also, the converse, do not do to others what you would not like done to yourself. The sources for this statement are manifold: Confucius, Aristotle, the New Testament, the Koran, the Talmud. It continued to turn up in such sources as McGuffey’s Reader (1837): “You know, my child, the Bible says that you must always do to other people, as you wish to have them do to you.” George Bernard Shaw, never one to be put off by age-old precepts, quipped, “Do not do unto others as you would they should unto you. Their tastes may not be the same” (Maxims for Revolutionists, 1902).
