Plato
428–348 BC · Ancient Greek
Oligarchy is a city divided by wealth, where love of money replaces love of honor, and the poor are excluded from rule.
In the eighth book of the , Plato sets forth an order of decline among constitutions, in which oligarchy occupies the place between timocracy and democracy. Oligarchy arises, on this account, when riches and rich men are honored in the state, and when the law fixes a sum of money as the qualification for citizenship, allowing no one whose property falls below the amount fixed to have any share in the government. The honor-loving rulers of the timocratic state, having begun to accumulate private wealth, rewrite the laws to protect what they have gathered, so that property replaces military valor as the title to office. A city so constituted, Socrates observes, is not one city but two, the one of the poor and the other of the rich, dwelling together and conspiring against each other. Plato also describes the soul that answers to this constitution, in which the appetite for gain rules over the spirited and rational parts, and the man who is governed by calculation rather than by conviction is thrifty, cautious, and outwardly respectable.
The objection Socrates raises against the oligarchical principle turns on the difference between wealth and the capacity to govern. Just think what would happen, he asks, if pilots were to be chosen according to their property, and a poor man were refused permission to steer even though he were the better pilot; to which Adeimantus agrees that in government, as in navigation, the probable result would be shipwreck. It may be noted that Plato does not always use the term in this sense. In the he divides the rule of the few into aristocracy, which has an auspicious name, and oligarchy, the one a government in which the few rule according to the laws, the other a lawless government by the few. In both, the few are the wealthy, so that wealth is there no more characteristic of oligarchy than of aristocracy.
"A government resting on a valuation of property, in which the rich have power and the poor man is deprived of it."
"Such a State is not one, but two States, the one of poor, the other of rich men; and they are living on the same spot and always conspiring against one another."
Plato's account of the divided city, and his parallel between the oligarchic soul and the oligarchic state, supplies the terms in which the later tradition conducts the argument. Aristotle takes up the classification and weighs the claims of rich and poor against one another; Aquinas restates the distinction between rule for the common good and rule for private interest; and Marx, in a much later age, renders the division of the city into two as the doctrine of class struggle. Whether the few who rule are men of virtue or men of property is a question treated more fully under the idea of Aristocracy, as the title that wealth may confer to political power is considered under Justice.
