Direct comparison of the ostensibly competing principles embedded in rival theories of Justice is often complicated by differences of view as to the nature and scope of the concrete Judgments a theory of Justice must attempt to illumine. Aristotle's official view, for example, is that Justice is a disposition or character trait. This commits him to scrutiny of Judgments about the Justice of particular actions since it is actions which serve to reveal, and to help form, the disposition in question. But it also stands in the way of any proper recognition of the fact that the competing principles of Justice he examines apply in the first instance neither to actions nor to dispositions but to states of affairs or situations: actions are Just for Aristotle when they help to bring about a Just distribution.
