The theme of the "Republic" is the relationship between the nature of justice and the existence of human beings. The first volume of the "Republic" includes critical examination of the nature of justice and virtue. Socrates established dialecticism with Thrasymachus, Polemarchus, and Cephalus. It led to the presentation and reply of questions refusing instructional logic, leading to a persuasive discussion on the true essence of justice. This is the main function of Volume 1 and is designed to remove mistakes and inappropriate justice statements to leave room for new theories.
In the Republic, Socrates tried to find the answer to controversial questions. What is justice? Through Book 1, he originally gave some definitions unrelated to him, so he decided to clarify them by asking the definition of "justice" by Cephalus and his son Polemarchus. In Volume 1, Socrates is about to leave a religious holiday when a group of people stops him and persuades him to remain in the late night celebration. - In Phaedrus of Plato, Socrates met Phaedrus who just talked with Lysias. Phaedrus walked Socrates with him and encouraged him to hear what he learned from talking to Lysias. They discussed and discussed the Lysias speech and discussed how to become a rhetorical speaker and whether writing is beneficial, acceptable or not
In the fourth part of Plato's "Republic", Socrates defines individual justice as well as state justice. I explained the definition of Socrates' s personal justice, then Socrates shows that he can not prove the correct definition of justice and raises further questions about justice. I assert that if we act according to this justice definition, we do not know when to take action. - In this article I will look into the Socratic argument of the Phaedo and Plato in the Republic of Plato in detail. First, I will first analyze the debate of human morality between the Republic, Socrates and the Glaucon. Discussion first defines a good community ethics and continues to apply this definition to humans. Then I will analyze Socrates' assertions about the immortality of the soul, the faedo.
