Book excerpt: To understand the international legal order in the field of criminal law, we need to ask three elementary questions. What is international law? What is criminal law? And what happens to these two fields when they are joined together? Volume Two of The Grammar of Criminal Law sets out to answer these questions through a series of twelve dichotomies - such as law vs. justice, intention vs. negligence, and causation vs. background events - that invite the reader to better understand the jurisprudential foundations of international criminal law. The book will appeal to anyone interested in the future of international cooperation in a time of national retrenchment, and will be of interest to students, scholars, and policymakers around the world.
