Plato
428–348 BC · Ancient Greek
The philosopher-king rules by wisdom, not by law; monarchy is the best regime when the ruler truly knows.
Plato treats the art of politics as a form of knowledge comparable to medicine or navigation, and he draws from this the conclusion that the man who possesses such knowledge has a title to rule whether or not his subjects consent. In the the Eleatic Stranger describes the true ruler as a royal weaver, one who combines the differing strands of civic character into a single fabric. Law occupies a secondary place on this view. It is a general prescription which cannot anticipate the particular case, and it is for that reason inferior to the living judgment of a man who knows. Whether such knowledge is ever available to a human ruler is a question Plato leaves open, and his answers to it differ from dialogue to dialogue. The standing of political knowledge among the arts and sciences is considered further under the ideas of Prudence and Wisdom.
The classifies constitutions by two criteria, the number of those who rule and whether the rulers govern according to established laws. Six forms result. Among those bound by law, monarchy stands first, aristocracy second, democracy third; among the lawless, the order is reversed, so that tyranny stands lowest of all. The reason offered turns on efficiency rather than on justice. Where the forms are otherwise equally lawful, government by one moves with less friction than government by a few or by many. Where the forms are lawless, one man unrestrained can go further in doing harm than a multitude which, as Plato remarks, is unable to accomplish either any great good or any great evil. This argument from unity of direction reappears in the modern defense of a single executive within a republic, and is treated more fully under the ideas of Government and Law.
Above all these forms Plato sets a government which, he says, excels them all and is among states what God is among men. It appears monarchical in type, yet it is not lawless in the manner of tyranny, since it stands above the need of written or customary rules altogether. The myth retold in the describes a god shepherding men and deciding every matter by wisdom without recourse to statute. In the the argument takes another direction. The Athenian Stranger, doubting that such a ruler will appear among men, proposes for the colony of Magnesia a constitution which combines monarchical authority with popular consent and the sovereignty of law. Plato thus seems to conceive monarchy in two quite distinct ways, as an absolute rule superior to law and also as one of the legally limited forms of government.
"These, whether they rule with the will, or against the will, of their subjects, with written laws or without written laws ... must be supposed ... to rule on some scientific principle."
"The best thing of all is, not that the law should rule, but that the king should rule, for the varieties of circumstances are endless, and no simple or universal rule can suit them all."
The two conceptions descend separately through the tradition. Aristotle takes up the first in his treatment of the god-like man whom it would be unjust to number among ordinary citizens, while the mixed constitution of the is developed by Aquinas and by later defenders of the mediaeval regime that is at once royal and political. Mill, denying that the rule of even a good despot could be an ideal, argues against both.
