The poetic representation of bad characters is also forbidden.

The musical training is to be adapted for disposing the mind to the perception of Beauty, whence it becomes qualified to recognize the other virtues.
Useful fictions are to be diffused, without regard to truth.

This pious fraud is openly recommended by Plato.
The division of the human mind into (1) REASON or Intelligence; (2) ENERGY, Courage, Spirit, or the Military Virtue; and (3) Many-headed APPETITE, all in mutual counter-play--is transferred to the State, each of the three parts being represented by one of the political orders or divisions of the community.

The happiness of the man and the happiness of the commonwealth are attained in the same way, namely, by realizing the four virtues--Wisdom, Courage, Temperance, Justice; with this condition, that Wisdom, or Reason, is sought only in the Ruling caste, the Elders; Courage, or Energy, only in the second caste, the Soldiers or Guardians; while Temperance and Justice (meaning almost the same thing) must inhere alike in all the three classes, and be the only thing expected in the third, the Working Multitude.
If it be now asked, what and where is Justice?
the answer is--'every man to attend to his own business.' Injustice occurs when any one abandons his post, or meddles with what does not belong to him; and more especially when any one of a lower division aspires to the function of a higher.

Such is Justice for the city, and such is it in the individual; the higher faculty--Reason, must control the two lower--Courage and Appetite.
