One’s search for the meaning of justice in Plato’s “Republic” would finally lead to two definitions: -Justice is Harmony.
-Justice is Doing one’s own job. Finding these two phrases, however, is hardly enough to get a clear sense of what justice is. Plato offers two main analogies to examine the definition of justice. The division of parts in the soul as well as the parts of the state; We would now examine the structure of the soul. The soul is divided into three parts, the appetitive, spirited and the rational. By the account of the parts of the soul we are shown how a soul has different wills, yet in order for a soul to stay in the just path it must have some sort of hierarchy. Plato describes the spirited part as the courageous ally of the rational part which has the control over the appetitiveve part.
The state is also divided into three types of people, the workers, soldiers and the rulers. It is obvious that that sort of division seems awkward when placed over our own capitalist society. We must keep in mind that in the republic that Plato is describing each individual is directed by vast education and the utmost care towards the work he could do with excellence. The children in the republic are separated from their parents at birth and therefore get the same equal chance of becoming workers or rulers without any prejudice regarding their upbringing or family background, rather, they are evaluated personally, purely according to their natural qualities.
The division of people into pre-determined types in the state is assumed to be done truthfully, according to their natural abilities. To soldiers who cannot understand what possessing wisdom means (because they lack it) or to workers that lack both courage and wisdom, Plato uses the “noble lie”. That is the idea that mother nature creates people out of three materials, gold, silver and bronze when obviously the golden people are fit to rule, the silver are fit
