Contrary to the traditional view that Plato had no international political thought, the paper interprets Plato’s Republic in order to search for Platonic international political thought. In particular, the paper focuses on the possibility of international extension of Platonic justice. First, the paper points out that the main arguments of Plato’s Republic develop along the line of international elements, for instance, the security issues of the ideal state and then shows that Plato apparently engages diverse international views ranging from realism, just war theory, to pacifism. Second, the paper reveals that Platonic political philosophy requires consistent explication of justice so that the harmony of individual soul is related ultimately to the cosmic harmony, the part of which is the relations of Hellenic world. From this perspective, the paper argues that the international extension of Platonic justice should be taken for granted. Thirdly, given that Plato accepted the possibility of international extension of Platonic justice, the paper reexamines the most relevant conversations in Book 1 of the Republic, that is, the conversations of Polemarchus and Socrates, and of Thrasymachus and Socrates, in order to show that Plato implies that the existence of philosophers and the popular approval of the philosophical life play important role for supporting the international justice. Finally, the paper concludes that the possibility of international extension of Platonic justice sheds a new light on the contemporary debates on global justice.
