Passage -3
Plato’s design of an autocratic rule by an aristocracy of the mind has received a lot of flak. But our assessment of his politics must here be limited to that of the kind of happiness it supposedly provides. Regardless of whether or not we find Plato's assumption plausible of an overall principle of the Good as the basis of the political order, his model state has, at least in theory, the advantage that it guarantees both internal and external peace. That is no mean feat in a society where interstate and civil wars were a constant threat, and often enough ended in the destruction of the entire city. In addition, the division of functions guarantees a high degree of efficiency, if every citizen does what he/she is naturally suited to do. But what about the citizens’ needs, beyond those for security and material goods? Are they to find their life’s fulfillment only in the pursuit of their jobs?
Plato seems to think so, when he characterizes each class by its specific kind of desire and its respective good : the philosophers are lovers of wisdom (philosophoi), the soldiers lovers of honor (philotimoi), and the workers are lovers of material goods (philochrêmatoi). That human beings find, or at least try to find, satisfaction in the kinds of goods they cherish is a point that is further pursued in the depiction of the decay of the city and its ruling citizens, from the best – the aristocracy of the mind – down to the worst – the tyranny of lust.
