What the ancient Greeks—at least in the archaic phase of their civilisation—called muthos was quite different from what we and the media nowadays call “myth”. For them a muthos was a true story, a story that unveils the true origin of the world and human beings. For us a myth is something to be “debunked”: a widespread, popular belief that is in fact false. In archaic Greece the memorable was transmitted orally through poetry, which often relied on myth. However, starting with the beginning of the seventh century BC two types of discourse emerged that were set in opposition to poetry: history (as shaped by, most notably, Thucydides) and philosophy (as shaped by the peri phuseōs tradition of the sixth and fifth centuries BC). These two types of discourse were naturalistic alternatives to the poetic accounts of things. Plato broke to some extent from the philosophical tradition of the sixth and fifth centuries in that he uses both traditional myths and myths he invents and gives them some role to play in his philosophical endeavor. He thus seems to attempt to overcome the traditional opposition between muthos and logos. There are many myths in Plato's dialogues: traditional myths, which he sometimes modifies, as well as myths that he invents, although many of these contain mythical elements from various traditions. Plato is both a myth teller and a myth maker. In general, he uses myth to inculcate in his less philosophical readers noble beliefs and/or teach them various philosophical matters that may be too difficult for them to follow if expounded in a blunt, philosophical discourse. More and more scholars have argued in recent years that in Plato myth and philosophy are tightly bound together, in spite of his occasional claim that they are opposed modes of discourse. . . .
