Answer:
Aristocracy. Aristocracy is the form of government (politeia) advocated in Plato's Republic. This regime is ruled by a philosopher king, and thus is grounded on wisdom and reason.
Explanation:
Plato attacked Athenian democracies for mistaking anarchy for freedom. The lack of coherent unity in Athenian democracy made Plato conclude that such democracies were a mere collection of individuals occupying a common space rather than a form of political organization.
