The stage that is not one of the five stages proposed by Plato is socialism, in which all political and economic activity are controlled by a community.
Plato's cycle includes the following stages:
- Aristocracy (or kingship) - the rule by a wise and virtuous leader.
- Timocracy - the rule based on honor and property.
- Oligarchy - rule by a few wealthy individuals.
- Democracy - rule by the masses, where leaders are elected by citizens.
- Tyranny - where democracy devolves into despotism under a single ruler.
Socialism, as described, does not fit into this framework.
