At the epoch when the Greco-Roman civilization was dissolving, when the labor of artisans and free workers began to be substituted for slave labor, pagan religion, philosophy and literature decided to accord them certain rights. The same Euripides who advised the slave to lose his personality in that of the master does not wish him to be despised. "There is nothing shameful in slavery but the name," says the pedagogue in Ion, "the slave, moreover, is not inferior to the free man when he has a noble heart." The mysteries of Eleusis and of Orphism, like Christianity, which continues their work, admit slaves among their initiated and promise them liberty, equality and happiness after death. The dominating class of the Middle Ages being military, the Christian religion and social ethics condemned lending money at interest, and covered the lender with infamy; to take interest for money loaned was then something so ignominious that the Jewish race, obliged to specialize itself in the trade of money, still bears the shame of it. But today, now that the Christians have become Jews, and the ruling class lives on the interest of its capital, the trade of the lender at interest is the most honorable, the most desirable, the most exclusive. The oppressed class, although the ideology of the oppressing class is imposed upon it, nevertheless elaborates religious, ethical and political ideas corresponding to its condition of life; vague and secret at first, they gain in precision and force in proportion as the oppressed class takes definite form and acquires the consciousness of its social utility and of its strength; and the hour of its emancipation is near when its conception of nature and of society opposes itself openly and boldly to that of the ruling class.
