plato is one of the most important figures of the Ancient Greek world and the entire history of Western thought. In his written dialogues he conveyed and expanded on the ideas and techniques of his teacher Socrates.
Glaucon points out that most people class justice among the first group. They view justice as a necessary evil, which we allow ourselves to suffer in order to avoid the greater evil that would befall us if we did away with it. Justice stems from human weakness and vulnerability. Since we can all suffer from each other’s injustices, we make a social contract agreeing to be just to one another. We only suffer under the burden of justice because we know we would suffer worse without it. Justice is not something practiced for its own sake but something one engages in out of fear and weakness.
