The dualism of modern just war theory

Published: June 2017Conventional modern just war theory is fundamentally incoherent. On the one hand, the theory contains a theory of public war wherein ethical responsibility for the justice of war belongs uniquely to political sovereigns while subjects, including soldiers, are obligated to serve in war upon the sovereign’s command. On the other hand, the theory contains a theory of discrimination which presupposes that participants in war, including soldiers, are responsible for the justice of the wars they fight. Moreover, these two components are derived from two inconsistent visions of political justice. The theory of public war, it turns out, is derived from a theory of justice that places the value of political society conceived of as a supra-individual communal entity above the value of the private individual. The theory of discrimination, however, is derived from a theory of justice that places the value of the private individual above that of political society. This inconsistency is revealed by analyzing the theories of Vitoria, Grotius, and Walzer. Appreciating this problem also helps situate the recent revisionist critiques of conventional just war theory.The research leading to these results has received funding from the European Research Council under the European Union’s Seventh Framework Programme (FP/2007-2013) / ERC Grant Agreement n.
