The conduct of war is subject to both moral and legal rules – for example, rules about who is a legitimate target, and who is not. What is the relationship between those moral and legal rules? Should we change the law of war so that its content mirrors the true morality of war? David Lefkowitz is Professor of Philosophy at the University of Richmond. He is the author of a book – Philosophy and International Law: A Critical Introduction – as well as numerous articles and book chapters on topics including the moral conduct of war, secession, and civil disobedience. During the 2016-2017 academic year, he served as a Fellow at the Stockdale Center for Ethical Leadership.
