Platonic View on Justice
In Plato’s view, justice does not mean a virtue which influences the individual, for instance, self-esteem and farsightedness. In Republic, Plato gave a definition of “justice in one’s soul”, which is compared to and assessed by social justice. Similar to a man’s soul, in society, justice consists of a permanent order of different human classes (Plato: 229). The Platonic conception of “justice in one’s soul” is pictured as similar to that of social justice and is related to some kind of order, namely a harmonious order in various parts of soul. Similarly, to Plato, social justice is the very harmonious order in various social classes.
Dealing with the nature of justice in Republic, Plato presented various forms of it such as the idea of justice as settling the debts or interests of the powerful. After rejecting these definitions of justice, he concluded that justice means order and harmony; in other words, the equilibrium of parts. After explaining social justice as an outcome of three groups of tradesmen, soldiers, and statesmen working in harmony with one another, he also generalized this division as the parts of the soul (Plato: 300). Moreover, Plato considered social justice a means of explaining individual justice.
Thus, it can be said that Plato posed and answered two questions at the same time: What kind of person is the just man? How can a just government come into existence? Furthermore, when he addressed the corruption of a country and the soul, he deemed them connected. In addition, he held that the just man could seldom be found except in a just country. However, the just country cannot be realized except in places where just men live.
Nonetheless, it must be said that Plato really limited the content of this virtue, since he viewed justice merely as the harmony of social classes. He considered it an image and reflection of the harmony of the individual soul. He proved that personal interests of the just one necessitate justice. Indeed, his motto was, “O’ man! Act justly or else your peace of mind and inner serenity will be at risk.”
Can Plato’s comparison of the individual and society corroborate his reference to an aristocratic government? If so, is the Platonic view on justice an aristocratic one? Also, can it be concluded that to Plato, there is no such thing as individual justice? When the concept of justice is connected to the individual, his relations with other individuals or with a group, including government, are explained. In other words, individual rights, which include justice, are others’ rights as well (Raphael: 117). But to Plato, the benchmark of man’s just action is knowledge about the images i.e., knowledge of eternal ideas, which is provided through the thinking of a good idea and toward which every virtuous person is moving. Unfortunately, only a few people can recognize the images (Becker, 1992: 44). Therefore, few are able to justify justice.
Moreover, this justification is comprehensible only to them. Of course, in the first place it must be proved that images exist.
Taking account of the faculties and parts of soul, Plato investigated four main virtues, namely wisdom, bravery, moderation, and justice in Republic. According to him, the soul has three faculties: reasoning faculty, faculty of will, and faculty of appetites. Whenever the faculties of will and appetites perform their tasks under the reasoning faculty, the virtues of bravery and self-control are obtained, respectively. Using the balance of the reasoning faculty, there emerges the virtue of wisdom. The virtue of justice is developed when all three faculties perform their tasks in harmony with one another. Hence, justice means harmony of parts of the soul.
In the Platonic system, bravery and virtue are included in one’s willpower, and wisdom is a virtue included in the reasoning part of the soul. Also, self-control is related to the faculty of desire. However, justice is a general virtue, that is, all parts of the soul should carry out their specific tasks appropriately.
It seems that Plato took this point into account that although each individual part might carry out its task well by itself, the outcome may not be desirable. Therefore, we need another virtue, namely, harmony of the parts of soul. Based on the Platonic view, the function of each individual part is the necessary but not the sufficient condition for the desired function of the whole. Rather, they must be in cooperation with one another.
According to Plato, compared to the rest of virtues, justice is the whole goodness, like the art of an architect compared to that of his subordinates in such a way that his work does not only belong to himself; it is his duty to guide others. Thus, justice is the condition for the existence of all other virtues because it causes other virtues to emerge in the society.
