What is justice? In Plato's Republic this very question is put forth as contentious. Plato disputes this question by using a method dialectic - the asking and answering of questions which lead the listener from one point to another, supposedly with irrefutable logic by obtaining agreement to each point before going onto the next, and so building an argument. Justice is looked at as an excellence of character. Its function is to improve human nature, which is a form of goodness that cannot be involved in injuring someone's character. Justice helps to keep our society from acting out from dissenting from our societies majority view. It helps to keep order and stability to help people to achieve human excellence. If there were no justice then our society would be a destructive one. Justice is in one sense the greatest virtue for it is the key to making other virtues work together for the common good.
Justice though, can be refuted and has been. Laws have been fought against and changed which is why our right to dissent from issues has been a right that we all take very seriously. We all have the right to dissent from a majority view. It's been done in the past and still exists in our society these days. The issues of abortion, gay marriages, and even stem cell replacement have all been controversial issues that have plagued us with picketing, letters to the government, and is even being argued about on TV and on the radio. We"ll never agree as a whole on the issues that concern us in our everyday lives. In order to establish such compliance between our societies we've come up with representatives to help us bring together, organize and voice issues to help our society establish the issues that must be reconciled with. There are those times though, that when an issue has been decided upon a few people have dissented from the decided judgment and they act out in very destructive actions.
