States as the main player in international relations, States as rational players, International System as the determinant of states behaviors, international system as an anarchic system, and considering independent nature for international institutions are the international institutionalism’ hypotheses that have been under critics by other IR Theory’s scholars. Given the explaining ability of the theory, how various schools of IR have appraised the ontological premises of Neo-Liberal Institutionalism? It seems that the mainstream theories of IR have criticized the functional part of the ontological premises of Neo-Liberal Institutionalism, while social theories have a criticism regarding its both functional and ontological angles.
