The author argues that the existing conceptual frameworks of political and social theory restrict both theorists and empirical researchers to a narrow definition of authoritarianism that focuses on governmental structure and fails to take account of forms of social control exercised outside the governmental sphere. Rather than define authoritarianism primarily by contrast to liberal democracy, Sciulli argues, we need to broaden our conception of authoritarianism to include "social authoritarianism," referring to social control imposed by private organizations and institutions, such as business corporations and professional associations. In this book, Sciulli develops an alternative conceptual framework, which he calls the theory of societal constitutionalism, and he explains how the theory can be used to assess whether social order in a society, whether democratic or authoritarian in political rule, is characterized by some degree of social authoritarianism. The book will be important reading for theorists in sociology, political science and legal studies.
