This book explores whether any theory alone is sufficiently capable of resolving the complexity of global justice, arguing that a combination of statism and cosmopolitanism is needed. In current times, xenophobia, nationalism and populism have amplified othering in both domestic and international politics. In global justice, the dichotomy between the ‘polis’ and the ‘cosmopolis’ separates statism from cosmopolitanism. Using resource curse as a complex case of global justice, the author demonstrates how neither statism nor cosmopolitanism alone are sufficient but goes on to argue that a combination of the two theories is simultaneously necessary and sufficient to resolve the complexity of global justice. He demonstrates how statism is primarily applied to the institutional dimensions of resource curse and only secondarily applied to the interactional dimensions, while cosmopolitanism is applied to the interactional dimensions but only secondarily applied to the institutional dimensions, and therefore a combination of both theories is needed to resolve the problem of resource curse – using the strength of the former to compensate for the weakness of the latter, and vice versa. Global justice is widely taught and researched as one of the most important areas in political philosophy and political theory. This book will be of great interest to students and researchers, philosophers and political scientists of African politics, political theory, political philosophy, international relations and international development.
