"Take the question of the nature of justice. We think of justice as an abstract standard that can be invoked in the criticism or evaluation of human actions and institutions. The content of justice is thought of as independent of all such actions and institutions: the fact that we punish criminals does not, in itself, show that it is just to punish criminals, for example. Nor can justice be regarded as simply a matter of conventional belief: the fact that people believe that it is just to punish criminals does not, in itself, make it just (someone who thinks otherwise has clearly failed to understand what justice is)."
