What are the laws of war? Who will hold belligerents to account? When is invasion or conquest justified? Is geopolitics always about self-interest and the survival of the fittest?
The invasion of the island of Melos by the Athenian empire in 416 BC brought all these questions to the fore. The historian Thucydides compressed some of these arguments in an elaborate debate, the ‘Melian Dialogue’, a chapter in his influential History of the Peloponnesian War. His account of the 27-year war between Athens and Sparta (431-404 BC) analyses the Athenians’ imperialism and belief in their superior strength.
We present a new work-in-progress reading of Colin Murphy’s gripping, highly topical, adaptation of the Melian Dialogue, with Ali White, Janet Moran, Shadaan Felfeli, and Morgan Jones. The short performance will be followed by an incisive panel discussion looking at the 2,500-year history of the ‘realist’ school of foreign policy.
The panel: foreign policy specialist, former Naval Vice Admiral, Mark Mellett, Classics Lecturer, Dr Kerry Phelan and Prof of Moral Theology, Tobias Winwright, will be chaired by Prof Brigid Laffan.
