Aristotle
384–322 BC · Ancient Greek
Government is legitimate when it rules for the common good, not the rulers' private advantage.
Aristotle provides what remains the foundational taxonomy of political forms. He distinguishes three legitimate constitutions, monarchy, aristocracy, and polity, from their three corrupted counterparts, tyranny, oligarchy, and democracy, by a single criterion: whether the government is directed to the common good of the whole community or to the private interest of the rulers. By this measure, a king who governs well and a popular assembly that governs well are alike legitimate; a single despot and a factious many are alike defective.
The criterion is, on its face, simple, but its application requires judgment. Aristotle is not disposed to argue that any one form is absolutely best regardless of circumstances; the polity, a mixed constitution that blends popular participation with the stability and quality provided by well-ordered institutions, is in most actual conditions the most durable arrangement. What matters in each case is not the number of those who rule but the end they serve. The distinction between legitimate and perverted forms of government is discussed in connection with the classification of constitutions in the chapter on CONSTITUTION.
Aristotle also insists that political community is natural to human beings, not an artificial remedy or a mere convenience. Man is by nature a political animal, and the person who lives outside a city is either a beast or a god. Government is not a necessary evil, as later contract theorists will argue, but the condition within which the fuller development of human nature becomes possible. The bearing of this claim on the question of human freedom and self-governance is considered in the chapter on LIBERTY.
"Man is by nature a political animal."
"Governments which have a regard to the common interest are constituted in accordance with strict principles of justice, and are therefore true forms; but those which regard only the interest of the rulers are all defective and perverted forms, for they are despotic."
Aristotle's taxonomy and his criterion of the common good shape every major discussion of government before and through Machiavelli. It is only when Machiavelli sets aside the question of whether rule serves the common good and asks instead whether it endures that the classical tradition is interrupted and a new kind of political analysis begins.
