In this article, I argue that Peter Fitzpatrick provides a unique contribution to international studies, most especially to contemporary interdisciplinary studies of International Law (IL) and International Relations (IR). Peter provides a significant theoretical contribution to the interdisciplinary study of IL and IR not only as a critical thinker of modern law, but also as a critical thinker of the modern international. On the one hand, his supplementary critical legal thinking contributes to a ‘decolonial deconstructionist’ rethinking of the politics of (...) international law. His close reading of how modern international law (auto)grounds ‘itself’, for instance, offers a strident critique of the racist, imperial, and colonial lines of discrimination involved in the negative (auto)constitution of this (supposedly) universal legal being. On the other hand, he provides a conception of the ‘(inter)national’ which displaces conventional, modern understandings of the legal and political organization of ‘humanity’ and ‘the world’, problematizing their foundational assumptions and spatialized geometrical frames as being based on oppositional dualisms (‘inside/outside’, ‘national/international’, ‘empire/modernity’, ‘theological/secular’, etc.), while offering a deconstructionist engagement with the ‘constitutive outside’ of the modern (inter)national. As a form of postcolonial counter-archive, Peter’s work enacts a decolonial deconstruction of ‘our’ (inter)national ‘selves’, including the (inter)national commonality ‘itself’. Before an incalculable, quasi-ontological heteronomy, a dissymmetrical Law of originary sociability which I (re)articulate here with/as the ‘and’ of the world(s), Peter’s supplementary critical thinking of the (inter)national contributes to imagining the world, humanity, and our social being(s), including law and language, otherwise.
