The idea

Plato, in the 'Republic', builds an ideal state on the model of the human soul. Reason, spirit and appetite in the soul match three classes: rulers, auxiliaries and producers. Justice means each class does its own work. Rulers must be philosophers, because only they know the Good.

Aristotle, in the 'Politics', is more practical. He compares real constitutions, sorts them by who rules and in whose interest, and prefers a mixed constitution resting on a large middle class.

Medieval thought turns on one question: who is supreme, Church or state? Augustine and Aquinas give the Church the higher purpose; Marsilius of Padua places the Church under the civil ruler.

Rules to remember

Common mistake

In Aristotle's scheme 'democracy' is a perverted form (rule of the many poor in their own interest). The good form of rule by the many is 'polity'.

Worked example

A small group of the richest citizens governs and uses its power to protect its own wealth. How would Aristotle classify this constitution?

  1. First question: how many rule? A few.
  2. Second question: in whose interest? Their own, not the common good, so it is a perverted form.
  3. The perverted form of rule by the few is oligarchy; its good counterpart is aristocracy.

Answer: Oligarchy.
