Competence and Just War

Abstract

This article argues that the Just War tradition would do well to consider the importance of competence – and that doing so would invigorate debates about the use of organized violence. The article defends this argument through several moves. First, inspired by Aristotle’s thoughts on phronesis and chance, we view competence as a practice among those who, as a matter of course, engage in practical reasoning that takes into account the contingency of political action. Second, following from Arendt, competence can be considered that which foregrounds means over ends. Third, because competence is a continuous and more vigilant consideration of justice within war, it extends through both jus ad bellum and jus in bello principles, including the ‘proper authority’ and ‘reasonable chance for success’ conditions of the former, and the ‘double effect’ doctrine discussed in the latter. The article concludes by acknowledging the challenges presented by an overemphasis on competence, before ultimately restating its purchase for Just War debates in the twenty-first century.
