In the Republic, Plato examines multiple forms of justice. The first of these that is taken into consideration is justice within one's soul. In this regard, Socrates (and therefore according to Plato) states that there are three parts of the soul, the basis of Plato's famous tripartite theory. These are reason (the deductive part that includes knowledge), appetite (which includes the desire for the more luxurious aspects of life), and spirit (which is essentially the drive and motivation of the soul). More specifically, reason and appetite are at odds with each other, and the spirit is a kind of "auxiliary", conforming to what is more dominant. Plato's view is that in the just man, reason triumphs and governs others, with the spirit as its servant and ally (Book 4, 441a and 441e). Desire, in the right man, is assigned a lower level than the two allies, which means that desires deemed unnecessary are limited so that the soul is not corrupted in satisfying them. The state of inner justice is achieved when the tripartite works in harmony, adhering to each of their individual duties without interfering in the affairs of others. In this regard, the soul is compared to an entire city, divided into similar classes: “financial (desire), auxiliary (spirit), and deliberative (reason)” (441a). When each class works in tandem while remaining true to their individual goals, justice is said to exist at the societal level. More importantly, Plato infers that even on the social level reason should be chief among the classes, and the ruler should be the voice of reason ("It is not fitting for the calculating party to rule", 441e). ' The ancestor example given by Glaucon, if Plato can be assumed to be of the same opinion, shows agreement with the...... center of the card......rn the meaning of justice of both texts is It is important to consider that there are multiple aspects of justice, each existing in a different form. Inner justice corresponds to social justice, while it differs from justice in action with others. All types of justice mentioned create a composite image of human nature: imperfect, opportunistic, and truly just in the man-to-man sense only when it is advantageous not to be unjust. This harsher, more realistic view of human nature is much more evident in the Republic than in the Second Treatise, where it is presented in a much more innocent light. Ultimately, Locke's vision of the state of nature and civil society is more solid than Glaucon's from a political point of view, but fails when it comes to delving into the philosophical aspect. Precisely for this reason Glaucon is more relevant when examined from a Platonic perspective.
