"The Spartan-inspired political system advocated by Plato in The Republic is totalitarian beyond the wildest dreams of a Hitler, Stalin or Pol Pot."

What do you make of the claim that The Republic isn't about an ideal state at all but is rather an allegory for how individuals should govern themselves (ideal "soul"), with "totalitarian reason" at the helm I suppose, and that it's even stated in the book itself that this is the case?
