 Debates about the scope of justice then become debates about whether different forms of human association are of the right kind to create agency in the relevant sense. Take the question of whether principles of social justice should apply to market transactions. If we see the market as a neutral arena in which many individual people freely pursue their own purposes, then the answer will be No. The only form of justice that arises will be justice in the conduct of each agent, who must avoid inflicting harm on others, must fulfil her contracts, and so forth. Whereas if we see the market as governed by a humanly-constructed system of rules that the participants collectively have the power to change – by legislation, for example – then we cannot avoid asking whether the outcomes it currently produces meet relevant standards of distributive justice, whatever we take these to be. A similar issue arises in the debate about over principles of global justice referred to above: is the current world order such that it makes sense to regard humanity as a whole as a collective agent responsible for the distributive outcomes it allows to occur?
