Book excerpt: In this lively and wide-ranging essay, Göran Ahrne sketches an organizational theory of society. Combining the insights of organization theory with the traditional concerns of social theory, he makes an innovative and creative contribution to both fields. Using a broad definition of organizations, the author shows that what goes on inside, outside and among organizations is central to understanding social relations. Organizations provide people with resources and motives, and they set the frames for human action. Although organizations do not form societies or systems, society is shaped and changed through interaction between organizations. Drawing on various schools of organization theory, including institutional, ecological and contingency theories, the book shows how their synthesis with social theory clarifies the nature and effects of organizational interactions.
