The Invention Of Custom by Francesca Iurlaro, Hardcover | Indigo Chapters

The concept of customary international law, although differently formulated, is already present in early modern European debates on natural law and the law of nations. However, no scholarly monograph has, until now, addressed the relationship between custom and the European natural law and iusgentium tradition. This book tells that neglected story, and offers a solid conceptual framework to contextualize and understand the 'problematic of custom', namely how to identify its normative content. Natural law doctrines, and the different ways in which they help construct human reason, provided custom with such normative content. This normative content consists of a set of fundamental moral values that help identify the status of custom as either a fundamental feature or an original source of ius gentium. This book explores what cultural values and practices facilitated theemergence of custom and rendered it into as a source of the law of nations, and how they did so. Two crucial issues form the core of the book's analysis. Firstly, it qualifies the nature of the interrelation between natural law and ius gentium, explaining why it matters in relation to ourunderstanding of the idea of custom. Second, the book claims that the process of custom formation as a source of law calls into question the role of the authority of history. The interpretation of the past through this approach can thus be described as one of 'invention'. | The Invention Of Custom by Francesca Iurlaro, Hardcover | Indigo Chapters
