The Sources and Status of Just War Principles

Abstract

Michael Walzer presents the theory of the just war that he develops in Just and Unjust Wars as a set of principles governing the initiation and conduct of war that are entailed by respect for the moral rights of individuals. I argue in this essay that some of the principles he defends do not and cannot derive from the basic moral rights of individuals and indeed, in some cases, explicitly permit the violation of those rights. I argue, further, that it does not follow, at least in some cases, that the principles are false. Even if some of the principles are not adaptations of a theory of rights to the problems of war, they may still be rational, pragmatic accommodations to epistemic and institutional constraints under which we must now act. Yet I also argue that respect for the rights that Walzer claims that individuals have requires us to try to overcome the epistemic and institutional impediments that restrict us at present. As those impediments are removed, the reasons for acknowledging and following some of the central principles Walzer espouses will diminish and, perhaps, disappear.
