Historical Background
Even though moral relativism did not become a prominent topic in philosophy or elsewhere until the twentieth century, it has ancient origins. In the classical Greek world, both the historian Herodotus and the sophist Protagoras appeared to endorse some form of relativism the latter attracted the attention of Plato in the Theaetetus. It should also be noted that the ancient Chinese philosopher Zhuangzi (read as Chuang-Tzu) put forward a non-objectivist view that is sometimes interpreted as a kind of relativism. Among the ancient Greek philosophers, most people consider the ideas of Plato but I will explain about the ideas of historian Herodotus, because I found his arguments to be interesting and what we call thinking out of the box. The historian Herodotus tells the story of how the Persian king Darius asked some Greeks at his court if there was any price for which they would be willing to eat their dead father’s bodies the way the Callatiae did. The Greeks said nothing could induce them to do this. Darius then asked some Callatiae who were present if they would ever consider burning their fathers’ bodies, as was the custom among Greeks. The Callatiae were horrified at the suggestion. Herodotus sees this story as vindicating the poet Pindar’s dictum that “custom is lord of all”; people’s beliefs and practices are shaped
