Democracy · Oligarchy
Why they are compared
Democracy and oligarchy were the two great rival constitutions of the classical Greek world — the rule of the many (the poor majority) against the rule of the few (the wealthy) — and the platform compares them because their conflict was, as Aristotle saw, the deepest fault line in the ancient city, and because the opposition remains one of the permanent axes of political life.
Where they converge
Both are, in Aristotle's analysis, defined by who rules — and both, in their pure forms, are corruptions: each is the rule of a part of the city in its own interest rather than for the common good. Democracy is the rule of the poor majority for the poor; oligarchy the rule of the rich minority for the rich. Both are unstable, because each excludes and antagonizes a large part of the city, breeding the faction (stasis) that destroys constitutions. The platform reads the two as the two faces of class conflict — the perennial struggle between the many poor and the few rich for control of the state.
Where they differ
The platform reads the contrast as the contrast between the two principles. The democratic principle is equality and freedom: all citizens share equally in ruling, offices are open to all (often filled by lot), and the will of the majority prevails — as in Athens. The oligarchic principle is merit measured by wealth: those with the greatest stake in the city (the propertied) should govern it, through councils and magistracies reserved to the qualified — as in many Greek cities and, in part, Sparta. The platform reads the deep disagreement as over what entitles one to rule: equal citizenship, or property and the stake it represents.
Strengths, limits, and the synthesis
The platform reads each as having a real strength and a real danger. Democracy gives every citizen a voice and a stake, drawing on the wisdom and energy of the whole community — but tends toward instability, demagoguery, and the tyranny of an unrestrained majority, the dangers Plato diagnosed. Oligarchy gives power to those with experience and a stake in stability — but tends toward the selfish rule of a narrow class and the resentment of the excluded majority. The platform reads Aristotle's answer as the enduring one: neither pure form is stable, and the best practicable constitution is the mixed government that blends the two, anchored by a strong middle class — the synthesis that tempers the excess of each. The platform draws no winner between the pure forms, reading both as partial and the balance between them as the goal.
