According to Plato, the ideal city was one that reflected the universe, on the one hand, and the individual on the other.
This is because he was unhappy with the city-states of his day, and was giving an alternative.
In Plato’s ideal state, three principal classes correspond to the three components of the soul.
This factor meant women were to be part of that change.
Allegedly, the features of the ideal state are mainly an interpretative contrivance.
