The analysis of Plato’s sociology makes it easy to present his political programme. His fundamental demands can be expressed in either of two formulæ, the ﬁrst corresponding to his idealist theory of change and rest, the second to his naturalism. The idealist formula is: Arrest all political change! Change is evil, rest divine1. All change can be arrested if the state is made an exact copy of its original, i.e. of the Form or Idea of the city. Should it be asked how this is practicable, we can reply with the naturalistic formula: Back to nature! Back to the original state of our forefathers, the primitive state founded in accordance with human nature, and therefore stable; back to the tribal patriarchy of the time before the Fall, to the natural class rule of the wise few over the ignorant many.
