Abstract

This paper examines Cécile Fabre’s cosmopolitan reductionist approach to war. It makes three main points. First, I show that Fabre must ‘thin down’ justice’s content in order to justify the cosmopolitan claim that the same rights and duties bind people everywhere. Second, I investigate Fabre’s account of the values at stake in national sovereignty and territorial integrity. Can cosmopolitanism explain why it is permissible to fight in defense of one’s political community? I doubt it. I argue that Fabre’s reductionist approach cannot justify national self-defense in many cases. Finally, I explore the role that authoritative institutions play in specifying the rights and duties we have under cosmopolitan justice. I believe Fabre takes an overly simple view of the relationship between rights, duties, and authoritative institutions. A more complex account may leave less space for private war on the part of individuals than she does
