A Critique of the Theories of Global Justice: Realism, Rawls, Habermas and Pogge

This paper discusses some of the proposals raised within the contemporary debate about normative models for a new international order. In the first part, the argumentative strategies of political realism, of John Rawls' liberalism and of Jurgen Habermas' deliberative model are presented. These authors' objections to the cosmopolitan idea of a transformation in the international order based on the demands for global economic justice are debated. In the last part, the text shows that the proposal f global justice presented by Thomas Pogge is insufficient because, although it shows the implication of the global economic order in the increase of poverty and formulates a global redistributive proposal, it does not consider the problem of the transformation of the prevailing system of power relations within the current capitalist order.
