Glaucon is known for his participation in the discussions that take place in the book, particularly in the dialogue about justice and the nature of the ideal city-state.

In the "Republic", Glaucon presents the famous argument known as the "Ring of Gyges" story, which questions whether people are inherently just or if they are only motivated by the fear of punishment. This argument serves as a key point in the philosophical exploration of ethics and morality in the book.
