The literature of international law has a shallow canon in comparison with other areas of law. Some believe that this is so because international law does not exist in a substantive way, as there is no court of all nations with any governing power. In International Law Afloat on a Sea of Religious Ethics, George Gatgounis explains how international law for the Western world before the 17th century derived much of its substance from religious ethics. Throughout the text, Gatgounis explores how religious ethics undergirded the early development of international law, and what an increasingly religiously diverse modern world means for the future of law on a global scale.
