Importance Of Justice In The Book II Of Plato's Republic

In Book II of Plato’s Republic, Glaucon seeks to define what justice is and whether it could truly be considered an end in itself. He starts by asserting that there are three types of good. First there are goods that we choose out pure enjoyment and pleasure, these goods have no negative after effects. Second are the goods that are valued for what they are in and of themselves not just the good that comes from them. Thirdly there are the goods that an individual will only pursue because of what they believe they will acquire, not for what they are themselves.(36) Glaucon believes that justice should be placed in the second tier of goods where everything of intrinsic value is also placed. However he goes on to explain that the majority of people

It is a middle ground between the best and the worst. The inclination of all is to do injustice without paying any price for that action, the worst is to suffer injustice without being able to take revenge (37). It follows then that justice becomes a mean between these two extreme scenarios. Most people will tend to value justice not because it is a good in itself but because they do not have the ability to do injustice without negative consequences. An individual that does possess the ability to practice injustice without consequence will therefore never willingly enter into agreement not to do injustice for the simple proclamation of not to suffer it. For a man such as this, that would be truly mad.
