Glaucon is the elder brother of Plato, the philosopher, who was born in Collytus. Together with his brother Plato, they formed part of the close rich students Socrates had. Glaucon at some point, queried the stands of Socrates on what justice truly means and he further stated that human beings are generally selfish. He also said that justice is not good in itself; human beings do act in a just manner because they cannot avoid doing that. An individual who is not just but is known to be just, seem happier than the person who is just but is known to always root for injustice.
