Aristotle’s Politics III is the start of the lineage, and it is not democratic theory. This continues from Hellas: Philosophy of the Polis, Aristotle’s Citizen, the Model of Sparta and Myth of the City, focusing on Aristotle, and explains the mean constitution, the deliberative life, and why Aristotle feared both the demos unbound and the expert unbound.
Aristotle opens the sustained analysis of citizenship in Politics III by defining the citizen as one who shares in the administration of justice and in holding office. Residence or descent alone does not suffice. The capacity to participate in ruling and in being ruled marks the free man inside a city of free men (Aristotle, Politics 3.1, 1275a22-33). Political rule, unlike the rule of a master over slaves or of a father over children, is exercised over equals. Because the citizens are similar in stock and free, none possesses a natural title to permanent command. The only arrangement consistent with that equality is rotation: each rules in turn and is ruled in turn. The arrangement is not a concession to democratic enthusiasm. It is the institutional expression of the claim that free men are capable of both commanding and obeying under law.
The mean constitution, which Aristotle calls polity, arises when the many who possess arms and a moderate property share in rule without the extremes of oligarchic exclusion or democratic leveling. It mixes the claim of the few to excellence with the claim of the many to freedom. The deliberative element remains central. Citizens assemble to judge what is advantageous and just for the city as a whole. That activity is not a mere aggregation of private preferences. It is the exercise of practical reason about common things. Where the deliberative body is captured by the unbound demos, decisions track the interest of the poor as a class. Where it is captured by experts who claim a permanent title, the citizens lose the practice of ruling and being ruled that forms political virtue. Aristotle treats both outcomes as deviations (Aristotle, Politics 3.7-8, 4.8-9).
The fear of the unbound demos is concrete. Extreme democracy, in which the assembly rules by decree and the poor use their numbers to confiscate the property of the rich, destroys the partnership in utility that makes a city more than a coetus (Myth: The Public Sacred Rites of the Ancient City). Law ceases to rule, and the momentary will of the majority replaces it. The fear of the unbound expert is equally concrete. Absolute kingship or a permanent council of the wise may decide well in a given case, yet it removes the citizens from the alternation of ruling and being ruled. The man who has never been ruled cannot rule well, because he has not learned the obedience that free men owe one another under law (Aristotle, Politics 3.4, 1277b7-16). Jason of Pherae, Aristotle notes, did not know how to live as a private man once he ceased to be tyrant. The political life requires both capacities.
Later republican readers recovered this page without converting it into democratic theory. The citizen who rules and is ruled in turn supplied the model for rotation of office, for the insistence that magistrates remain accountable, and for the rejection of any permanent title to rule, whether hereditary or technical. The mean constitution offered a criterion for judging mixtures: each element must be strong enough to prevent the others from decaying into their pure corrupt forms, yet none may extinguish the deliberative participation of free men. The Greek text itself, not a later seminar paraphrase, remains the starting point of the lineage.
