 [I]f evidence of global economic and political interdependence shows the existence of a global scheme of social cooperation, we should not view national boundaries as having fundamental moral significance. Since boundaries are not coextensive with the scope of social cooperation, they do not mark the limits of social obligation. Thus the parties to the original position cannot be assumed to know that they are members of a particular national society, choosing principles of justice primarily for that society. The veil of ignorance must extend to all matters of national citizenship, and the principles chosen will therefore apply globally. (Beitz 1979b: 151)
