Sparta. It is hard to know why Plato thought it was so great. Perhaps he was thinking of the fact that Athens at the time was under Spartan rule and was doing fairly well.

Perhaps he was thinking of a kind of synergy between Athens and Sparta? After all that is what existed in his time and it was the time that he and  Aristotle wrote and many other advances came about.
