There remains only Justice for us to discover. Wherein does the Justice of the city reside? Not far off. Its justice consists in that which we pointed out at first as the fundamental characteristic of the city, when we required each citizen to discharge one function, and one alone--that for which he was best fitted by nature. That each citizen shall do his own work, and not meddle with others in their work--that each shall enjoy his own property, as well as do his own work--this is true Justice.[99] It is the fundamental condition without which neither temperance, nor courage, nor wisdom could exist; and it fills up the good remaining after we have allowed for the effects of the preceding three.[100] All the four are alike indispensable to make up the entire Good of the city: Justice, or each person (man, woman, freeman, slave, craftsman, guardian) doing his or her own work--Temperance, or unanimity as to command and obedience between Chiefs, Guardians, and the remaining citizens--Courage, or the adherence of the Guardians to right reason, respecting what is terrible and not terrible--Wisdom, or the tutelary superintendence of the Chiefs, who protect each person in the enjoyment of his own property.[101] [Footnote 99: Plato, Republic, iv. pp. 432-433. 433 A: [Greek: Kai\ mê\n o(/ti ge to\ ta\ au(tou= pra/ttein kai\ mê\ polupragmonei=n dikaiosu/nê e)sti/, kai\ tou=to a)/llôn te pollô=n a)kêko/amen, kai\ au)toi\ polla/kis ei)rê/kamen.] 433 E.
