 The scope of the public determines who to idealize. Public justification theorists typically identify the public with members of a traditional nation-state. Theorists do this to simplify, but also due to an implicit nationalism. Rawls confined his theory of justice to members of a nation, though he later developed an account of public justification for global matters (2002). This matter is left to debates about nationalism and cosmopolitanism (see the entries on  nationalism  and  cosmopolitanism).
