>Given Plato's deep conviction that injustice was a fundamental problem, how did his understanding of the internal disharmony within the individual soul serve as the foundational root of all external and political injustices, and what does this imply about Plato's view on the primary remedy for a just society?
Rule by Appetite: An individual driven solely by insatiable desires for pleasure or wealth (e.g., a greedy merchant or a hedonist) will inevitably act unjustly. They will lie, cheat, steal, or exploit others to satisfy their unbridled appetites. Their actions in the external world reflect their internal slavery to desire.
