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.

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 first book to consider German sociologist Niklas Luhmann's social theory in a critical legal context. His theory is introduced here both in terms of society at large and the legal system specifically, and the book reveals the aporetic structure of autopoiesis, aligning it with postmodern approaches to law. Readers will find it operates both as an introduction to the relevance of Luhmann's social theory for law, as well as a critical response to autopoiesis.

Niklas Luhmann (1927-1998) was a German sociologist and system theorist who wrote on law, economics, politics, art, religion, ecology, mass media, and love. Luhmann advocated a radical constructivism and antihumanism, or "grand theory," to explain society within a universal theoretical framework. Nevertheless, despite being an iconoclast, Luhmann is viewed as a political conservative. Hans-Georg Moeller challenges this legacy, repositioning Luhmann as an explosive thinker critical of Western humanism. Moeller focuses on Luhmann's shift from philosophy to theory, which introduced new perspectives on the contemporary world. For centuries, the task of philosophy meant transforming contingency into necessity, in the sense that philosophy enabled an understanding of the necessity of everything that appeared contingent. Luhmann pursued the opposite—the transformation of necessity into contingency. Boldly breaking with the heritage of Western thought, Luhmann denied the central role of humans in social theory, particularly the possibility of autonomous agency. In this way, after Copernicus's cosmological, Darwin's biological, and Freud's psychological deconstructions of anthropocentrism, he added a sociological "fourth insult" to human vanity. A theoretical shift toward complex system-environment relations helped Luhmann "accidentally" solve one of Western philosophy's primary problems: mind-body dualism. By pulling communication into the mix, Luhmann rendered the Platonic dualist heritage obsolete. Moeller's clarity opens such formulations to general understanding and directly relates Luhmannian theory to contemporary social issues. He also captures for the first time a Luhmannian attitude toward society and life, defined through the cultivation of modesty, irony, and equanimity.

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.

Perhaps more than any other social theorist in recent history, Niklas Luhmann's work has aroused extreme, and often antagonistic, responses. It has generated controversies about its political implications, its resolute anti-humanism and its ambitious critique of more established definitions of society, social theory and sociology. Now, however, a steadily growing number of scholars working in many different disciplines have begun to use aspects of Luhmann's sociology as an important methodological stimulus and as a theoretical framework for reorientating their studies. This collection of essays includes critical and reconstructive contributions by a number of distinguished social theorists, political theorists, legal scholars and empirical sociologists. Together, they provide evidence of Luhmann's extensive and diverse relevance to the issues facing contemporary society, and, at the same time, they enhance our understanding of the challenges posed by his theoretical paradigm to more traditional conceptions of social theory.

Niklas Luhmann is recognised as a major social theorist, and his treatise on the sociology of law is a classic text. For Luhmann, law provides the framework of the state, lawyers are the main human resource for the state, and legal theory provides the most suitable base from which to theorize on the nature of society. He explores the concept of law in the light of a general theory of social systems, showing the important part law plays in resolving fundamental problems a society may face. He then goes on to discuss in detail how modern 'positive' – as opposed to ‘natural’ – law comes to fulfil this function. The work as a whole is not only a contribution to legal sociology, but a major work in social theory. With a revised translation, and a new introduction by Martin Albrow.
