The Republic is a renowned book that largely describes the transitional life process of Plato. The book demonstrates Plato shift from Socrates ideology and the habit of questioning individuals on the streets. Plato uses the book to demonstrate his new approach to philosophy by expounding on the concept of justice. He argues that there are two types of political justice, one of which is concerned about the individual and the other about the state. His first part of the book concentrates on division of things into three categories according to Glaucon, which is also one of my favorite parts of the book.

The best part of the book is the beginning part of book 2. After Socrates responds to Thrasymachus, he thinks that it is the end of the discussion on justice. However, others are dissatisfied with the Socrates’ conclusion. Among those who are not satisfied with Socrates’ conclusion is one of his young companions, Glaucon. According to Glaucon, goods are divisible into three sections. The first section talks of goods that individual desires because the results are rewarding for instance physical exercise and massage. The second category according to Glaucon is about goods one desires only for their own sake, for instance happiness. The third and most valuable category is about things individuals’ desire for their own sake and the results they derive from them, for instance, good health and knowledge (Plato, bk.2).

The reason this part is my favorite is because Plato, through Glaucon, teaches the world that justice is not just desirable because of its consequences as Socrates believe. In contrast, justice is a commodity that most individuals and nation states desire for their own happiness and for its rewarding results. For that reason, with reference to Glaucon, justice should be on the third and most valuable category.
