Niklas Luhmann offers an accessible introduction to one of the most important sociologists of our time. It presents the key concepts within Luhmann’s multifaceted theory of modern society, and compares them with the work of other key social theorists such as Jürgen Habermas, Michel Foucault, and Zygmunt Bauman. The book pays particular attention to introducing and discussing Luhmann’s original sociological systems theory. It presents a thorough investigation into the different phases of his oeuvre, through which both the shifting emphases as well as the continuities in his thinking are shown. The primary focus of this text is Luhmann’s theory of modern society as being differentiated into a plethora of ‘function systems’ – such as politics, law, and economy – which operate according to their own distinct logics and which cannot interfere with one another. For Luhmann, this functional differentiation works as a bulwark against totalitarian rule, and as such is a key foundation of modern democracy. Furthermore, the book critically examines the implications of this functional differentiation for inclusion and exclusion dynamics, as well as for the understanding of power and politics. This is a key text for both undergraduate and postgraduate students of areas including contemporary social theory, political sociology, and sociology.

Germany's most prominent social thinker here sets out a contribution to sociology that aims to rework our understanding of meaning and communication. He links social theory to recent theoretical developments in scientific disciplines.

Niklas Luhmann ranks as one of the most important sociologists and social theorists of the twentieth century. Through his many books he developed a highly original form of systems theory that has been hugely influential in a wide variety of disciplines. In Introduction to Systems Theory, Luhmann explains the key ideas of general and sociological systems theory and supplies a wealth of examples to illustrate his approach. The book offers a wide range of concepts and theorems that can be applied to politics and the economy, religion and science, art and education, organization and the family. Moreover, Luhmann’s ideas address important contemporary issues in such diverse fields as cognitive science, ecology, and the study of social movements. This book provides all the necessary resources for readers to work through the foundations of systems theory – no other work by Luhmann is as clear and accessible as this. There is also much here that will be of great interest to more advanced scholars and practitioners in sociology and the social sciences.

Niklas Luhmann is widely recognized as one of the most original thinkers in the social sciences today. This major new work further develops the theories of the author by offering a challenging analysis of the relationship between society and the environment. Luhmann extends the concept of "ecology" to refer to any analysis that looks at connections between social systems and the surrounding environment. He traces the development of the notion of "environment" from the medieval idea—which encompasses both human and natural systems—to our modern definition, which separates social systems from the external environment. In Luhmann's thought, human beings form part of the environment, while social systems consist only of communications. Utilizing this distinctive theoretical perspective, Luhmann presents a comprehensive catalog of society's reactions to environmental problems. He investigates the spheres of the economy, law, science, politics, religion, and education to show how these areas relate to environmental issues. Ecological Communication is an important work that critically examines claims central to our society—claims to modernity and rationality. It will be of great importance to scholars and students in sociology, political science, philosophy, anthropology, and law.

However, unlike conventional legal theory, this volume seeks to provide an answer in terms of a general social theory: a methodology that answers this question in a manner applicable not only to law, but also to all the other complex and highly differentiated systems within modern society, such as politics, the economy, religion, the media, and education. This truly sociological approach offers profound insights into the relationships between law and all of these other social systems.

This is the definitive analysis of art as a social and perceptual system by Germany's leading social theorist of the late 20th century. It combines three decades of research in the social sciences, phenomenology, evolutionary biology, cybernetics, and information theory with an intimate knowledge of art history, literature, aesthetics, and contemporary literary theory.

Niklas Luhmann's social theory stands in direct opposition to the dominant 'anthropocentric' traditions of legal and political analysis. King and Thornhill now offer the first comprehensive, critical examination of Luhmann's highly original theory of the operations of the legal and political systems. They describe how from the perspective of his 'sociological enlightenment' Luhmann continually calls to account the certainties, the ambitions and rational foundations of The Enlightenment and the idealized versions of law and politics which they have produced.
