This thought-provoking book develops and elaborates on the artifact theory of law, covering a wide range of related theoretical and practical topics. Offering a range of perspectives that flesh out the artifact theory of law, it also introduces criticisms of previous formulations of the theory and inquires into its potential payoffs. Featuring international contributions from both noted and up-and-coming scholars in law and philosophy, the book is divided into two parts. The first part further explores and evaluates the concept of law as an artifact and analyses the background and theoretical basis of the theory. The second part comprises three sections on legal ontology, semantics and legal normativity, specifically in relation to law's artifactual nature. Providing cutting-edge insights at the intersection of law and philosophy, this book will appeal to scholars and students in philosophy of law, empirical legal studies, social ontology and the philosophy of society.
