Progress in International Law is a comprehensive accounting of international law for our times. Forty leading international law theorists analyze the most significant current issues in international law and their critical assessments draw diverse conclusions about the current state and future prospects of international law. The material is grouped under the headings: The History and Theory of International Law; The Sources of International Law and Their Application in the United States; International Actors; International Jurisdiction and International Jurisprudence; The Use of Force and the World's Peace; and The Challenge of Protecting the Environment and Human Rights. The book draws its inspiration from a similar survey undertaken in 1932 by Harvard Law Professor and PCIJ Judge Manley O. Hudson. In his book Progress in International Organization, Hudson sought to demonstrate that what he perceived as an emerging international infrastructure, and as moves toward the rule of law in international affairs, were sure signs of human progress towards peace and cooperation. Progress in International Law critically engages with that claim as a normative matter and, at the same time, presents the evidence by which a judgment about our own progress towards peace and cooperation might be judged.
