Justice Exemplified by Plato and Thucydides

618 Words2 Pages

Plato's Book I of The Republics presents three fundamental views on justice which are exemplified in Thucydides' On Justice, Power and Human Nature. Justice is illustrated as speaking the paying one's debts, helping one's friends and harming one's enemies, and the advantage of the stronger.

In both their works, Plato and Thucydides write of the view that justice is honoring one's debts. In The Republics, Cephalus asserts that justice is "the truth and giving back what a man has taken from another." In other words, he believes that we should be truthful and pay back our debts to man and the gods. This view of justice is illustrated at the debate in Sparta between the Lacedaemonians, Corinthians and the Athenians. During the Athenians defense, they remind the Lacedaemonians of the battle with Persia. In this conflict, when Persia was defeated, the Athenians claim to have supplied most of the fleet, the most "intelligent commander" and their most "unhesitating zeal," (Thucydides, i.74). Athens risked their lives for homes that barely survived, and fought to save the Lacedaemonians as well as themselves. Therefore the Lacedaemonians are obligated to not dissolve the treaty or break their oaths with Athens. The Athenians feel that it is just to pay back this debt, which is a similar perspective of justice advanced by Cephalus.

Also Plato and Thucydides incorporate the concept that justice is helping one's friends and harming one's enemies. Polemarchus, in The Republics, states that he agrees with Simonides' maxim that it is "just to give each what is owed," (Plato, 331e). This leads to Polemarchus' assertion that that justice is doing good to friends...

...ssert that it is just to expand their empire because they are stronger, and it has always been established that the weaker are to be ruled by the stronger. Those with power to use force, "have no need to go to law," and the weaker must give in to the stronger. The Athenians felt that their intentions were just, and according to Thrasymachus, they were.

In conclusion three notions of justice developed in Book I of The Republics of Plato are outlined in On Justice, Power and Human Nature. Justice is viewed as telling the truth and paying debts, doing good to friends and harm to enemies, and the advantage of the stronger.
