Political philosophy

The Philosopher-King

Plato's most famous and most contested political proposal — that cities will have no rest from evils until philosophers rule or rulers philosophize — and the long argument it began about whether wisdom can or should govern.

The proposal

The philosopher-king is Plato's most famous and most contested political idea: the claim, set out in the Republic, that cities will have no rest from their evils "until philosophers become kings, or those now called kings genuinely and adequately philosophize." The platform reads it as the boldest assertion ever made for the rule of wisdom — that the right to govern belongs to those who know the good, and that political power and philosophical understanding must be united in the same persons or the city cannot be just.

The argument behind it

The platform reads the proposal as following from Plato's deepest convictions rather than as an arbitrary preference. If justice is a kind of knowledge — knowledge of the good and of the right ordering of the soul and the city — then only those who possess that knowledge are competent to rule, just as only the navigator who knows navigation should steer the ship. The philosopher, who alone has ascended to the knowledge of the Forms and the Good, is therefore the only fully legitimate ruler. The platform reads this under virtue and knowledge: the philosopher-king is the political consequence of the Socratic identification of virtue with knowledge.

The permanent objection

The platform reads the philosopher-king as the origin of a permanent debate rather than a settled doctrine. The obvious objections are ancient and modern alike: that no one possesses the certain knowledge of the good the proposal requires; that the union of absolute power with the claim to absolute wisdom is the formula for tyranny; that the philosopher may be unfit for, or unwilling to descend to, the grubby work of ruling. Plato himself returned to the problem in the Statesman and the Laws, increasingly conceding that, in the absence of the ideal ruler, the rule of law is the necessary second-best. The platform reads this development as Plato's own qualification of his most famous idea.

Why it matters for Virtue & Power

The philosopher-king is the platform's central case for the claim that wisdom should govern — the strongest statement of the ideal against which every realist account of politics, from Aristotle to the present, defines itself. It is read at length in the philosopher king and stands behind the whole of Plato's political thought, taken up in Plato and political order.
