He believes that people will fear the amount of consequences that may arise through injustice and therefore choose justice over injustice3. He gives the example of the ancestor of Gyges of Lydia being possessed. Originally a Shepherd to the ruler of Lydia, he found a gold ring through a chasm that was created by a thunderstorm and earthquake. With this ring, was the power of invisibility; he figures out how to use this power and decides to use it against the king by seducing his wife and ultimately taking over the kingdom. He reemphasizes his point that an unjust person would perform the same injustice as a just person given this circumstance and when someone thinks he can do injustice with impunity, he does it. Also, someone who didn't want to do injustice, given this sort of opportunity, and who didn't touch other people's property would be thought wretched and stupid.4 Glaucon's last point to his argument is that people who live an unjust life are much happier, wealthier and more extravagant life than one that participates in a just life. His argument states that if you place most pure form of an unjust man beside a just man, the unjust man is viewed as righteous and has substantial wealth and friends to support him.5 The just person who is noble, is viewed as someone with no reputation and not honorable.6 Therefore, Glaucon reveals that eventually the just person will be more likely to commit crimes against another and therefore will drown in unhappiness making the unjust person the happiest of the extremes. .
The evidence that Glaucon provides is proof that the life of an unjust person is much better than the life of a just person because in these two pure extremes, the just person who was not given any reputation was stripped of honors which were given to the unjust person making the unjust happier than the just. .
However, I do not agree with Glaucon's position about justice even if his intent was to make Socrates give his true meaning of justice.
