In a context of profound transformations, including within both disciplines, the mainstream, liberal, and rationalist calls for interdisciplinarity were met with critique and opposition in both International Law (IL) and International Relations (IR). In Chapter 3, I turn to an-other story of interdisciplinary relations, giving special attention to international legal critiques (Klabbers 2005, 2009; Koskenniemi 2001, 2007c, 2009a) that strongly opposed the interdisciplinary dual agenda, and most skeptically questioned the conceptual space within which IL and IR scholars (supposedly) cohabited (Slaughter, 1993, 1995). More precisely, I engage with the story of counterdisciplinarity (Klabbers 2010; Koskenniemi 2012c). In so doing, however, I also aim to displace both stories (of interdisciplinarity and counterdisciplinarity), reorienting attention toward a different but correlated set of problems concerning the politics of international law. For this purpose, I offer a close, critical reading of (some of) the works of Martti Koskenniemi. Following a deconstructionist, post-foundational political thought, I displace Koskenniemi’s critical international legal thinking, drawing attention to a splitting of politics from within the very notion of politics (re)articulated in different forms with-in his own engagements with the “politics” of international law. Noticing a certain disregard for the international, I propose moving to another story of interdisciplinarity.
