Plato identified the four cardinal virtues with the classes of the city described in "The Republic", and with the faculties of man. Plato narrates a discussion of the character of a good city where the following is agreed upon. “Clearly, then, it will be wise, brave, temperate healthy-minded, and just.” (427e; see also 435b) "Temperance"—Cicero and Plato sometimes preferred the word "sōphrosynē"—was common to all classes, but primarily associated with the producing classes, the farmers and craftsmen, and with the animal appetites, to whom no special virtue was assigned; "fortitude" was assigned to the warrior class and to the spirited element in man; "prudence" to the rulers and to reason. "Justice" stands outside the class system and divisions of man, and rules the proper relationship among the three of them.
