Andrew Linklater has been one of the most innovative thinkers in international relations, introducing critical and ethical elements into the discipline which has forced it to rethink many of its basic assumptions. This book builds on this body of work to develop a radical new theory that calls for a cosmopolitan approach to international relations.

Key subjects covered in the book include:

• citizenship and humanity
• critical theory and political community
• the problem of harm
• the sociology of states-systems.
