The Philosophy of War and Exile argues that our current paradigms for thinking about the ethics of war - just war theory - and the suffering of war - PTSD theory - judge war without a proper understanding of war. By continuing the investigations of J. Glenn Gray into the meaning of how war is experienced by combatants we can find an alternative understanding of not only war, but of peace, culminating in a new theory of responsibility centered around embodiment and mortality rather than praise and blame. This conception of responsibility will in turn allow us to not only ask new questions about torture, unmanned warfare, and the treatment of veterans, but also to ask new questions about what it means for noncombatants to experience as home what combatants experience as exile.
