EducationAll the citizens receive a class-specific education.
For guardians “this education is most often noted for its carefully censored ‘reading list;’ the young guardians-to-be will not be exposed to inappropriate images of gods and human beings… A well-trained guardian will ‘praise fine things, be pleased by them, receive them into his soul, and, being nurtured by them, become fine and good,’ and each will ‘rightly object to what is shameful, hating it while he’s still young and unable to grasp the reason’… Socrates has the young guardians not only responding to good things as honorable (with spirited attitudes), but also becoming fine and good.”
For auxiliaries military education is available.
For producers there is primary education “to make good on the commitment to promote especially talented children born among the producers and to enable the producers to recognize the virtue in the philosophers.”
