Socrates talked about how to cultivate excellent guardians, who should have two blended principles, temperate and courageous.
Contradict virtues
Last chapter, he first pictured a simplified edition of state, where shoemaker, cook, smith and some other people live together. We can make out that whether for one man or for the whole state, each one devoting to his own occupation and coordinating with others is the most efficient way. When it comes to the education of the guardians, of which the demand is indeed a paradox. He should be a good fighter so as to defend for the state against the enemies, but he must be gentle at the same time to be loyal to his own state. However, the situation above appears in the nature-a bred dog is obedience to his owner but also fierce to the strangers. Thus it is reasonable to find people with the combination of two virtues. The education process of the enquiry of desired guardians will throw light on the question- how do justice and injustice grow up in States?
Story to tell
He suggested that we shouldn’t tell young people certain kind stories of gods, in which gods’ behavior abused regulations. It is well known to us that Greek tales are composed of incidents violating moral disciplines. For example, Cronus successfully led the rebellion against his father, and he swallowed his children in case they overthrowing him, the only survivor Zeus still executed the terror.
Music and gymnastic
The main idea of Socrates to educate children is to strengthen their physical power by gymnastic and improve their mental stages.
Rhythm and harmony find their way into the inward places of the soul
And there is a difference between physicians and judges, the former should be noble in order to cure others, but the latter should be mature enough because he must be experienced of the wickedness in human to find out the truth behind cases. Socrates suggested tests to examine whether youth are qualified for the rulers and guardians. They should have no property for their own, but food and money can just meet the ends.
