Divided into two parts, this book examines the train of social theory from the 19th century, through to the `organization of modernity', in relation to ideas of social planning, and as contributors to the `rationalistic revolution' of the `golden age' of capitalism in the 1950s and 60s. Part two examines key concepts in the social sciences. It begins with some of the broadest concepts used by social scientists: choice, decision, action and institution and moves on to examine the `collectivist alternative': the concepts of society, culture and polity, which are often dismissed as untenable by postmodernists today. This is a major contribution to contemporary social theory and provides a host of essential insights into the task of social scie.
