Introduction Justice in Greek times differs from our definition today. Today we associate justice with the successful implementation and execution οf political law, however, to the Ancient Greek’s justice was used to describe the proper and correct method for living. Justice is harmony and was believed it could be achieved through learning. Before examining the true nature of justice, Plato first establishes that justice is good (and consequently part of the good life) in Book I. The individuals in Plato’s audience attempt to describe their own version of justice: Cephalus argues that justice is a matter of self-interest; Polemarchus suggests justice is helping one’s friends and harming one’s enemies, and finally Thrasymachus proclaims that justice is the advantage οf the stronger. Plato listens to these theories and argues that justice is an excellence of character. The role that justice plays is to improve human nature. In addition to other things, justice is a form of goodness that cannot participate in any activity that attempts to harm one’s character. Plato employs argument by analogies to enhance the theory that justice is one of the things that comprise ‘goodness’. He compares the art of living to the musician’s art. A musician has knowledge οf music and by this, he is better in music than one that lacks musical knowledge. The musician does not wish to transcend others who share his knowledge, he just wants to be superior to those ‘unmusical’ individuals. The same idea applies to the just man – he wants to outdo the unjust individual, but not those of his own kind. On the other hand, the unjust individual is self-serving and wants to be better than those both just and unjust alike. Plato goes on to dispel the theory that justice is power by showing that there is no loyalty among the unjust giving the example that it “causes civil war, hatred and fighting among themselves” (the famous ‘no honor among thieves’ idea). With justice established as something good, the nature of justice must now be examined Main body Plato addresses the nature of justice in Book II beginning with a warning: “The inquiry we are undertaking is no easy one but calls for keen vision.” It requires looking into the soul of human character and takes an acuter vision than most people possess, somehow justice must be enlarged to gain a clearer understanding. Plato enlarges the concept οf justice by bringing in the analogy of justice in the Kallipolis (the just state). After justice is visible in the soul of the city, it can be illuminated in the individual soul. He begins to construct the first city with the help of Adeimantus, analyzing the fundamental parts of societal life that correspond to the needs οf human life. Plato says “We will create a city but the real city will be our needs.” The goal is not to create ‘happy’ individuals in the state, because happiness is an elusive idea, unique to each individual. As Plato shows, a happy state is one in which each class performs its own tasks with its specialized function. Justice in the individual is of greater concern than happiness as a fundamental quality of life. Plato begins the creation of the Kallipolis by providing the basic necessities of life – housing, food, clothing, and the ability to produce such items. Each person performs specialized tasks and the city grows and begins trading goods and services with other cities. During this process
