Most of us take it for granted that wars in defence of one's political community are the quintessential just wars. Indeed, while in recent years philosophers have subjected all of our other assumptions about just war theory to radical revision, this principle has emerged largely unscathed. But what underpins the morality of defensive war? In this book, leading moral and political philosophers both show the profoundly challenging nature of that question, and advance novel answers to it. The first part exposes the deep tension between the individualist foundations of much contemporary philosophy and plausible conclusions about the morality of defensive war. The second part offers an individualist attempt to resolve that tension, while the third seeks to justify defensive war by appeal to more collectivist values.

Recent years have seen a resurgence of interest, among both philosophers, legal scholars, and military experts, on the ethics of war. Due in part due to post 9/11 events, this resurgence is also due to a growing theoretical sophistication among scholars in this area. Recently there has been very influential work published on the justificaton of killing in self-defense and war, and the topic of the ethics of war is now more important than ever as a discrete field. The 28 commissioned chapters in this Handbook will present a comprehensive overview of the field as well as make significant and novel contributions, and collectively they will set the terms of the debate for the next decade. Lazar and Frowe will invite the leading scholars in the field to write on topics that are new to them, making the volume a compilation of fresh ideas rather than a rehash of earlier work. The volume will be dicided into five sections: Method, History, Resort, Conduct, and Aftermath. The contributors will be a mix of junior and senior figures, and will include well known scholars like Michael Walzer, Jeff McMahan, and David Rodin.

Killing civilians is worse than killing soldiers. If any moral principle commands near universal assent, this one does. It is written into every major historical and religious tradition that has addressed armed conflict. It is uncompromisingly inscribed in international law. It underpins and informs public discussion of conflict-we always ask first how many civilians died? And it guides political practice, at least in liberal democracies, both in how we fight our wars and in which wars we fight. Few moral principles have been more widely and more viscerally affirmed than this one. And yet, in recent years it has faced a rising tide of dissent. Political and military leaders seeking to slip the constraints of the laws of war have cavilled and qualified. Their complaints have been unwittingly aided by philosophers who, rebuilding just war theory from its foundations, have concluded that this principle is at best a useful fiction. Sparing Civilians aims to turn this tide, and to vindicate international law, and the ruptured consensus. In doing so, Seth Lazar develops new insights into the morality of harm, relevant to everyone interested in normative ethics and political philosophy.
