Abstract

Plato’s political philosophy is usually seen in the context of domestic politics, justice within a polis. This essay argues that Plato had views on international relations theory as well. We show that Plato had a theory of the causes of international conflict, and that his theory can be seen as a response to Thucydides’ theory as well as theories espoused by other Greek thinkers. Plato’s theory can be generalized to a theory of causation in the social sciences. He also had clear views on what international relations theorists now call “hegemonic stability theory,” “transition theory,” and the nature of political sovereignty.
