According to Lyotard we can no more support our universal values in any philosophical system. Plurality is the greatest sign of our time and we should think of justice based on it and not against it. It doesn't mean reducing the justice question to opinion games or power relations, but it means conceive it based on an Idea, whose universality and finality are exactly the Idea of coexistence of difference and it would have a regulatory function over the diversity of opinions. The Idea of plurality can have an important function, because when we judge, we don't consider only the present, we also consider what we wish for the future of human beings and the world. If this Idea can't unify our values and assure peace, it can at least help us avoid the confusion between unity or universality and domination and claim the coexistence of differences.
