without always adding "other people think intolerance of certain behaviours is moral". Philosophers like Russell Blackford even argue that intolerance is, to some degree, important. As he puts it, "we need not adopt a quietism about moral traditions that cause hardship and suffering. Nor need we passively accept the moral norms of our own respective societies, to the extent that they are ineffective or counterproductive or simply unnecessary". That is, it is perfectly reasonable (and practical) for a person or group to defend their subjective values against others, even if there is no universal prescription or morality. We can also criticize other cultures for failing to pursue even their own goals effectively. The moral relativists may also still try to make sense of non-universal statements like "in this country, it is wrong to do X" or even "to me, it is right to do Y". Moral universalists argue further that their system often does justify tolerance, and that disagreement with moral systems does not always demand interference, and certainly not aggressive interference. For example, the utilitarian might call another society's practice 'ignorant' or 'less moral', but there would still be much debate about courses of action (e.g. whether to focus on providing better education, or technology, etc.). History Moral relativism encompasses views and arguments that people in various cultures have held over several thousand years. For example, the ancient Jaina Anekantavada principle of Mahavira (c. 599–527 BC) states that truth and reality are perceived differently from diverse points of view, and that no single point of view is the complete truth; and the Greek philosopher Protagoras (c. 481–420 BC) famously asserted that "man is the measure of all things". The Greek historian Herodotus (c. 484–420 BC) observed that each society regards its own belief system and way of doing things as better than all others. Sextus Empiricus and other ancient Pyrrhonist philosophers denied the existence of objective morality. In the early modern era Baruch Spinoza (1632–1677) notably held that nothing is inherently good or evil. The 18th-century Enlightenment philosopher David Hume (1711–1776) serves in several important respects as the father both of modern emotivism and of moral relativism, though Hume himself did not espouse relativism. He distinguished between matters of fact and matters of value, and suggested that moral judgments consist of the latter, for they do not deal with verifiable facts obtained in the world, but only with our
