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.

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.

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.

This analysis of the historical evolution and contemporary form of the system of world politics utilizes contemporary theories and debates in sociology and global history. Critically reflecting also on world politics in the field of international relations, this book will appeal to a wide readership in a range of fields.

Fifty years ago, the two leading German philosophers and sociologists since the Second World War, Jürgen Habermas and Niklas Luhmann, embarked on a sweeping and contentious debate that would continue for decades. Their coauthored 1971 book Theory of Society or Social Technology laid out their opposing positions on meaning, communication, consensus, and dissent—and ultimately the foundations of modern social thought. Habermas and Luhmann would elaborate their disagreement in the years to come in a controversy whose aftershocks divided social theorists by presenting what appeared to be two fundamentally divergent views of the nature of society and what systems theory was capable of explaining. This is the first book in English about one of the most important conflicts in social theory today. Gorm Harste analyzes the Habermas-Luhmann debate from its inception through Habermas’s most recent works, exploring issues such as methodology, ideology, truth, history, and politics. He contextualizes their positions in terms of how each grappled with the legacy of Nazism and sought to provide grounding for an antitotalitarian politics. Harste follows the evolution of the debate, as the fundamental dispute over the normative and practical desirability of agreement and disagreement came to touch upon political questions including the rule of law, the separation of powers, human rights, individualization, and secularization. Ultimately, Harste emphasizes the convergence between Habermas and Luhmann—and the pressing need for social theorists to further unite these two formative accounts of contemporary society.
