“If such things as primitive communism, group-marriage, and matriarchy were admitted into the beginnings of Greek civilisation, what would become of the dogma, on which the ruling class leant more and more heavily as the city-state declined, that its economic basis in private property, slave labour, and the subjection of women rested on natural justice? If the writings of the later materialists, Demokritos and Epicurus, had not perished, we might well have possessed a more penetrating analysis of early Greek society than Aristotle’s. But they perished partly for that reason. Plato wanted the works of Demokritos to be burnt, and his wish has been fulfilled.”
