The Moral Theologian, Oliver O'Donovan and International Law

Abstract

Oliver O'Donovan renders a singular contribution to the theory and history of international law by identifying the spiritual impoverishment of the discipline following the triumph of state-centred contractarianism in the theory of international relations, with Hobbes, Locke, Kant and, for the present, John Rawls. This contractarian approach to international society has an inherent tendency, which O'Donovan highlights, to ground international order in the hegemonic claim of one or two countries to represent the values of the whole of humanity. With a combination of rational moral theology and biblical interpretation (Revelation), O'Donovan reasserts an international order grounded in the autonomous identities of the nations, which God has recognized as equal. With a theory of political legitimacy which rests upon representation of national identity, O'Donovan points the way to an international order based upon mutual respect among nations under natural law, in the classical medieval sense finally represented by Grotius and Suarez. This article describes again what the natural law tradition meant in the hands of Aquinas and Vitoria, in order to highlight the fact that the ontological dimension of natural law theory provides a way to meet the intolerable insecurities which theories of nationalism appear to generate. Then the article goes on to offer one way to bring natural law thinking up to date for contemporary audiences by drawing upon Paul Ricoeur's phenomenological theory of mutual recognition and respect among the nations as a way of going beyond the contractarian tradition in contemporary international law and relations theory.
