This book investigates the role of law and legal experts in the organizational dynamics of a population. It demonstrates that law is a stable practice among those who are called upon to select the ?normative facts? of a population, that is, the interactional standards that are proclaimed as binding for the entire population by the publicly recognized legal experts. To do this, the author proposes an integration of the recent research outcomes achieved in three different areas of study?legal positivism, legal institutionalism and legal pluralism. He examines the notions of rule, coercion, institution and practice elaborated on by significant theorists in these fields, highlighting both the merits and flaws and ultimately advancing a notion of law and a description of the legal field which are able to account for the nature of the legal field as the cradle of social order. This text covers key guidelines for empirical research and political activities in Western and non-Western countries.
