Getting on to the Same Page: War, Moral Fundamentalism, and Convention

Uwe Steinhoff’s The Ethics of War and the Force of Law contains an extended critique of ‘moral fundamentalism’, or the project of uncovering an individualist ‘deep morality’ of war governed by the same moral principles and rules that govern ordinary moral life, as well as a more positive account of war that depicts it as a social practice. Much of Steinhoff’s account is indebted to a series of claims involving the standing to blame, reciprocity, and the necessity and proportionality conditions on self-defence. On all these claims, Steinhoff is open to challenge. First, he is arguably over-dependent on ‘standing to blame’ considerations. Second, his commitment to reciprocity is under-explained. Third, the necessity condition does not clearly explain how conventional elements explain the formation of defensive standards. Fourth, there are problems in explaining how the distinct defensive conventions adopted by distinct communities can actually be made to get on to the same page when these communities go to war with each other.
