This book is concerned with how we can make sense of the confusing landscape of individualistic explanation in international law. Arguing that international law lacks the vocabulary to deal with the collective dimension and therefore perpetuates an individualistic vocabulary, the book develops and articulates a more appropriate collective approach for public international law. In doing so, it reframes longstanding problems such as the conflict between self-determination and the integrity of states and the effects and the limits of state sovereignty in an increasingly globalized world. Presenting fresh perspectives on a range of contemporary issues in international law, the book draws on the work of major contributors to legal and political theory.
