Scholars know of no culture, past or present, that does not have a system of morality. Even though moral standards may vary from one culture to another, or even within a particular culture, every culture distinguishes “what is” from “what ought to be.” It is impossible for a culture either to rise above morality or to get out from under it.

Second, the moral diversity we have all heard so much about is in fact vastly exaggerated. In particular, the major religions of the world, which represent the vast majority of humans on the planet, disagree quite a bit about God but agree quite a bit about morality. All the major religions have some form of the Golden Rule: do unto others as you would have them to do unto you. In 1993 theologian Hans Ming assembled a “parliament” of leading representatives of the world’s religions, including Jews, Christians, Muslims, Hindus, and Buddhists. The group issued a declaration of common beliefs, including a wide range of moral values that are held across religious boundaries.
