Quote

One of the great tragedies of mankind is that morality has been hijacked by religion. - Arthur C. Clarke

How true! If anyone suggests that without religion, there is no moral, then it is an insult to one fifth of the world's population, Chinese, who traditionally live under the moral guideline of Confucius (551 B.C.E. – 479 B.C.E.) who has laid down the moral law: never impose on others what you would not choose for yourself 己所不欲、勿施於人

This Confucius moral ideas have deep cultural influence to Chinese, Korean, Japanese and Vietnames. It is said way earlier than the bible.
