In Plato’s Republic, he advocates for a society that would have three main classes: the ruling class (or guardians), the auxiliary class, and the business class. He believes that justice is based on the harmonious operation of these three classes and law must be based on justice in order for it to be obeyed by all citizens. The ruling class must have wisdom, courage, and moderation while the business class only needs to be interested in serving the community. Lastly, monarchy is proposed as the best form of government for Plato’s Republic.
