Global governance has become part of the international relations vocabulary. As an analytical category and as a political project it is a strong tool that illustrates the major complexities of world politics in contexts of globalization. The study of global governance has expanded and superseded traditional approaches to international relations that focus on relations among states. Moreover, the study of global governance and has included nonstate actors and their dynamics into a more intricate thematic agenda of global politics. However, global governance has become less a political space of deliberation and more of a managerial aspect of world politics because of some assumptions about reality, humanity, and the international community. It would appear that this is a result of the predominance of liberal thought in world politics after the end of the Cold War. Regardless of how diverse the approaches to global governance may appear, the ontological assumptions—that is, the beliefs about reality that are behind its definition, conceptualization, and implementation as political projects—are not neutral nor are they universal. These assumptions respond to specific appreciations of reality and are inherited from Western modernity. The problem with this is that claims to contemplate the interests of humanity as a whole abound in global governance institutions and arrangements, whereas in fact global governance is constructed by neglecting other possible realities about the world. The consequences of this conceptualization are important in the sense that global governance becomes a tool of exclusion. Only by taking into consideration the ontological difference through which global governance can reflect the complexities of a diverse world can one explore the importance of alternative governances as a way to consider how global orders can be approached. Such alternative global governances draw from ontological pluralism and conceive political global orders as based on the coexistence and negotiation of different realities.
