Plato's Republic is a Socratic dialogue authored by Plato around 375 BC that explores the concept of justice and its relationship to individual virtue and political theory. In the dialogue, Socrates discusses with various Athenians and foreigners the meaning of justice and whether a just person is happier than an unjust one. Plato's theory of justice is centred on the belief that just individuals and a just society are interconnected, with the character of the state depending on the character of its citizens. He identifies virtues that suit each social class, arguing that a just person with a balanced soul operates according to values and desires that cannot lead to unjust actions. According to Plato, a just person's love of the forms motivates them to do what is just in relation to others while also pursuing their interests. Plato's concept of philosopher-kings, who represent reason and ensure good governance, is a cornerstone of his theory of justice.

What You'll Learn

Justice as a personal virtue
Plato's Republic revolves around a central question: is it always better to be just than unjust? In the text, Socrates attempts to answer this question by sketching what a good city would look like, arguing that defining justice as a virtue of a city helps to define justice as a virtue of a human being.
Socrates' defence of justice centres on the idea that it is always in one's interest to be just and act justly, presenting the just person as one with a balanced soul. He argues that the just person's soul entails desires for certain kinds of objects, the most important of which is knowledge. The pursuit of knowledge, according to Socrates, requires extreme effort and dedication, and thus the just person will pursue learning rather than indulging in desires that lead to unjust actions.
Socrates further links his discussion of personal justice to justice in the city, claiming that a good city would be just, and that a just city is possible. He suggests that the just person will do what is just in relation to others while also acting in their own self-interest. This approach argues that the just person's good is realised by doing what is also good for others.
Plato's concept of justice as a personal virtue has been compared to Aristotle's model of virtues of character, which views justice as an intermediate or mean between vices of excess and defect. However, critics like David Sachs argue that Socrates fails to adequately defend justice, as he does not demonstrate why a balanced soul leads to just actions or why psychic health amounts to justice.
Despite these criticisms, Plato's Republic remains a significant contribution to ethical and political philosophy, exploring the nature of justice and its relationship to individual happiness and societal well-being.

Justice in the city
Plato's Republic presents a complex and nuanced understanding of justice, particularly in the context of the city or state. At the heart of Plato's philosophy is the belief that justice is not merely a legal or constitutional concept but something far more intrinsic to human nature and the natural order.
Plato's concept of justice is informed by his understanding of the world as a hierarchical and harmonious whole, where every individual and species has a purpose. This belief in a natural order extends to his vision of an ideal city, where each person knows their place and contributes to the city's well-ordered functioning. In this sense, justice, for Plato, is about ensuring that everyone can fulfil their role and purpose, providing for themselves and seeking the Good.
Plato's ideal city is often criticised as a ""nowhere-utopia"" because it is seen as an unrealistic reflection of human nature and potential. However, this critique assumes that Plato's ideal city is meant to be a direct blueprint for society, which may not be the case. Instead, Plato may be using the city as a metaphor or thought experiment to understand justice as a virtue, both in the individual and the collective sense.
In the Republic, Socrates, a key mouthpiece for Plato's ideas, defends justice as a virtue by arguing against the notion that self-interest of the ruler is justice. Instead, Socrates suggests that a just person, with a balanced soul, acts according to certain values and desires that inherently prevent unjust actions. This defence of justice is further strengthened by the idea that a person's own good is realised through actions that benefit others, creating a harmonious and just society.
Plato's understanding of justice in the city, therefore, revolves around the idea of individuals fulfilling their roles and purposes while contributing to the collective good. This vision of justice is a far cry from the power-politics mentality criticised by Plato, where laws are exploited for selfish purposes. Instead, Plato's just city is one where individuals act with virtue, moderation, and respect for the community, creating a harmonious whole.

The just person's love of the forms
Plato's Theory of Forms, also known as Platonic idealism or Platonic realism, is a philosophical theory that posits that the physical world is less real or true than Forms. Forms, in this context, refer to the timeless, absolute, non-physical, and unchangeable essences of all things, which objects and matter in the physical world merely participate in, imitate, or resemble.
Plato believed that before our bodies existed, our souls inhabited a heavenly realm where they became acquainted with these Forms. According to Plato, true knowledge is knowledge of these Forms, and it cannot be attained through sensory experience. Instead, it is a memory of our souls' initial acquaintance with the Forms in heaven.
In "The Republic," Plato explores the question of justice and argues that a life devoted to virtue and knowledge will result in happiness for the individual. The virtuous person, according to Plato, is one whose soul is balanced and working harmoniously, with their reason cognizant of the Form of the Good and other Forms.
The just person with a balanced soul, as described by Socrates, operates according to certain values and desires that cannot lead to unjust actions. Their soul desires knowledge, and they pursue learning instead of indulging in desires that typically lead to injustice. This pursuit of knowledge is a key aspect of the just person's love of the Forms, as they strive to understand and embody these abstract ideals in their lives.

Justice and psychic health
Plato's Republic revolves around a fundamental question: is it always preferable to be just than unjust? To answer this, Socrates takes an indirect approach, proposing that a good city would be just and that defining justice as a virtue of a city would help define justice as a virtue of a human being. This dialogue explores two central questions: "What is justice?" and "Is justice connected to happiness?"
In Plato's Republic, Socrates defines justice as having a balanced soul, which critics like David Sachs argue is a defence of psychic health rather than justice. Sachs claims that Socrates fails to demonstrate how having a balanced soul leads to just actions or why psychic health equates to justice. Sachs suggests that justice includes actions and considerations of others' well-being and strong motivations to avoid unjust acts.
To counter Sachs' critique, commentators have attempted to bridge the gap between a just soul and just actions. One approach suggests that a person with a balanced soul operates according to values and desires that inherently prevent unjust actions. Another interpretation, as suggested by Norman Dahl, is that the just person's own good is realised by doing what is also good for others, driven by their love of the forms.
Plato's concept of justice as psychic health has been interpreted through various medical analogies. For instance, Socrates' defence of justice has been criticised for not providing compelling reasons to believe that a person with a balanced soul would refrain from unjust acts like theft, murder, or adultery. However, others have argued that a person with a balanced soul would inherently avoid such acts due to their values and desires.
Plato's Republic presents a complex exploration of justice, happiness, and their interconnection. The dialogue delves into various subjects, including rival theories of justice, views of human happiness, education, philosophy, and political regimes. The interpretation of Plato's justice as psychic health adds another layer of complexity to the understanding of his philosophical work.

Justice and self-determination
Plato's concept of justice is inspired by his conviction that the collective takes ethical precedence over the individual. In other words, he believes that there is a cosmic order into which each person is supposed to fit, and that virtue and duty are far more important than rights. In Plato's eyes, justice is a "master virtue", with wisdom, courage, and self-discipline also being important virtues.
Plato's Republic centres on the question: is it always better to be just than unjust? In the Republic, Socrates sets out to defend the idea that it is always in one's interest to be just and act justly. He presents the just person as one who has a balanced soul. However, critics such as David Sachs argue that Socrates fails to show why having a balanced soul will lead one to act justly or why psychic health amounts to justice.
In response to Sachs' critique, commentators have come to Socrates' defence, attempting to bridge the gap between a just soul and just actions. One approach is to show that the just person with a balanced soul operates according to certain values and desires which cannot lead to unjust actions. The just person's soul entails desires for certain kinds of objects, the most important of which is knowledge.
Plato's concept of justice has been criticised for underestimating the value of self-determination. In Plato's utopia, everyone except the guardians is forced to live their lives in a fundamentally unfree way. This lack of freedom will lead to a lack of self-respect and discontent, which will upset the psychological equilibrium of the individual.
Despite these criticisms, elements of Plato's philosophy can be reconciled with elements of liberal democratic ideology. For example, Plato was right that the interests of the individual ultimately coincide with the interests of the community. However, he failed to understand the prerequisites of the self-harmony that he believed constituted individual and communal happiness, namely freedom and the perception that one's sense of self is appreciated by others.
