Definition Of Justice In Plato's Republic By Socrates And Polemarchus

Superior Essays
In Book I of Plato’s Republic, Socrates and Polemarchus debate the assertion “it is just to give to each what is owed to him,” that Simonides originally theorized. The postulation develops from Cephalus’ prior claim that a just man is one who “speaks the truth and repays his debts” (331d). Socrates undermines Cephalus’ definition of justice by proposing a scenario wherein a madman lends a sword to a friend, and the friend may either return the weapon or keep it from the obviously dangerous individual. Socrates concludes that returning the weapon, which would be the “just” action according to Cephalus because it constitutes honest repayment, is unjust. In his debate with Polemarchus, Socrates once again critiques the proposed relationship between …show more content…
These analogies relate justice to professions and animals in an attempt to refine the definition Socrates seeks. Socrates ultimately comes to the conclusion that justice cannot be “to give each what is owed to him.” Socrates and Polemarchus both agree that because it is never just to hurt another man, to give each man--be he good or bad--what he “owes” is fundamentally unjust. The philosopher is closer to a definition of justice because he can reject Polemarchus’ assertion as a potential answer to the query “what is justice?” However, I take issue with Socrates’ theory of justice as a craft, and further, the idea that hurting another is never just on account of Socrates’ weak analogies and vague …show more content…
Following Socrates’ contention that Simonides would side with Cephalus and return a weapon to a madman, Polemarchus narrows his definition of justice, by claiming that justice is to give each what they deserve or is “appropriate to him.” Further, when prompted by Socrates, Polemarchus claims that medicine lends, or “gives medicine, food and health to bodies” (332c) and cooking gives seasoning to meat. Thus, Polemarchus comes to the conclusion that justice must give or “owe” what is good to friends and what is bad to enemies. Socrates then asks his interlocutor which profession or craft is most just in its treatment of others. He claims that, for example, a doctor will treat a sick patient with more skill than a just man, and conversely, be more adept at harming a patient, if he “deserves bad.” Polemarchus replies that justice is useful in war and peacetime only when it protects objects or money, otherwise a skillful man is preferred. Thus, Socrates concludes that if justice is a craft, it is “only useful for useless things,” such as watching money or a lyre. Furthermore, Polemarchus’ first premise, is critiqued by Plato on the grounds that (1) if justice is a craft, a more skilled individual is more equipped to “give what is owed” than a just one, and (2) that Polemarchus’ argument reduces justice to

    After Socrates, the protagonist in Plato’s Republic, refutes a description of justice similar to the traditional poetic view of justice made by a man named Cephalus, Thrasymachus, a well-known sophist, enters into the discussion of justice with Socrates. Thrasymachus asserts, “I proclaim that justice is nothing else than the interest of the stronger” (Plato, Republic I, 338 C). For Thrasymachus, justice is only revealed through the interests of the stronger party. Whatever the stronger party dictates as being good for itself, the stronger party, is what justice is. To further elaborate on his claim, Thrasymachus uses examples of cities governed by different ruling bodies.…

    In this model, both justice and injustice have been forgotten, and it is not until Glaucon’s suggestion of luxuries and opulence that these contrasting ideals seem to come into perspective. This alludes to the notion that when wants, such as luxuries and desires, are introduced into the city, is when the concept of injustice is introduced. By creating circumstances that lead others to develop jealousy and greed, it ultimately stimulates the manipulation of unjust acts. Due to this realization, Socrates has created a just city that is only based on needs and diminishes the idea of wants. Therefore, he concludes that justice within a city is a means and an end and preserves the duty of the citizens to themselves as well as others.…

    While attempting to find the correct meaning of the word justice, Socrates refutes several of Thrasymachus's arguments pertaining to his personal perception of the definition. Furthermore, Socrates counters Thrasymachus's belief that one should be unjust, with the conviction that justice is a trait which one should possess. This particular area of the discussion shows a contrast between the ideas of Socrates and Thrasymachus regarding the term. One of Thrasymachus's arguments that Socrates takes issue with is that in which he states that unjust rulers and cities are the strongest, making justice something that the less powerful and the unwise should aspire to obtain.…

    One's soul is made up of three parts: the rational, the spirited and the appetitive/passionate. Justice is formed when the rational rules, the spirit serves reason, and temptation and appetite exist in moderation, guided by reason. A man is therefore just to himself when he allows his rational part to make decisions and for his spirit to fight for and give courage to such decisions. Injustice, according to Socrates, is a kind of civil war between the three parts of the soul. Justice within a man forms just actions, whereas injustice produces unjust…

    Glaucon is unsatisfied with the argument between Thrasymachus and Socrates regarding Justice. Thrasymachus believes Justice is for the common good, it is not for the good for an individual, that any compromise is involved. Glaucon renews Thrasymachus’ argument, he divides the good into three classes: things good in themselves, things good both in themselves and for their consequences, and things good only for their consequences. Socrates places justice in the class of things good in themselves and for their consequences without any hesitation. Glaucon wants Socrates to prove by exploring that Justice is best, not a compromise.…

    As anyone might expect, Socrates tests every one, uncovering all shortcomings or constraints in the quest for Truth. The second definition of equity, obedience to the enthusiasm of the stronger, is Thrasymachus' hidden avocation for oppression, and is foreshadowed in his coarse interest for installment. He is depicted in sharp difference to Socrates (Carawan, 2008), who recommends that the more grounded may not know his advantage; in this way, on occasion, it is essential for the weaker to resist him. Socrates then effectively annoys the definition…

    The Melians, the response of Athenians at Melos, and Pericles at his plague speech, all confirm the argument that the question of justice is at least relevant between those with unequal power. In Pericles’ case, the question of justice could influence the subjects of Athens to commit great violence against its oppressor. Justice, then, is real in that it influences action. It is absurd, then, to assert that an abstract principle like justice does not exist while at the same time admitting that it influences people; its influence is proof of its existence. Beyond this philosophical proof for the existence of justice, Athens’ own cries for justice further demonstrate the relevance and importance of questions of justice between those of unequal…

    The switch to the discussion of profitability changes the scale in which justice is analyzed from justice as an overarching concept to an individual in action. From his view, justice has a key role in society but for an individual it is more profitable to be unjust. As a moral skeptic, Thrasymachus doesn’t believe justice to hold an intrinsic good. For an…

    In Plato’s Crito, Socrates proposes that one should never return a wrong with a wrong because returning a wrong would be unjust. Retaliation produces injury and injury is an injustice that should never be committed under any circumstance. Despite being placed in prison for the wrong reasons, Socrates decides not to leave since escaping would only mean harming Athens, the land that gave him everything. Although Socrates has reasonable arguments as to why he shouldn’t leave, Socrates fails to comprehend that retaliation can sometimes be justified.…

    Justice has been an evolutionary concept that has been forever evolving for thousands of years. However, in order for the modern deduction of justice to have been made by modern standards, the concept of justice itself needs to be established. Although its formal understanding may have been unclear during their time period, Hesiod and Homer both attempt to understand and exert their opinions as to what justice is through their epic poems and other works. Even though some of their views on justice conflict and others compliment each other, they both laid a foundation to explain what justice meant in Greek society.…

    In Plato’s Republic, the images of justice are perceived differently between several characters in this novel. Cephalus, Polemarchus, and Thrasymachus, all present contrasting ideals of justice compared to the one envisioned by Socrates. Using the art of rhetoric, Socrates utilizes argumentation to identify the faults in each individual’s vision of justice, and how his unconventional perception of justices can change their entire society. The first vision of justice discussed in The Republic was Cephalus. Cephalus describes justice as honesty.…
