1. *This article is the text of the first of three Uehiro Lectures that I presented at the Oxford Uehiro Centre for Practical Ethics in May and June of 2006. A revised and expanded version of this lecture will be published, along with expanded versions of the two other lectures, in a book provisionally titledThe Ethics of Killing in War. This book will appear in the Clarendon Press's Oxford Uehiro Series in Practical Ethics under the editorship of Julian Savulescu. The other two lectures deal, respectively, with whether the exculpating factors that often apply to unjust combatants impose a requirement of restraint in fighting against them, and whether civilians can be morally liable to military attack.
