The Nature And Functions Of Law

A philosophical approach to American system of law.

What is the nature of law and what is the best way to discover it? This book argues that law is best understood in terms of the social functions it performs wherever it is found in human society. In order to support this claim, law is explained as a kind of institution and as a kind of artefact. To say that it is an institution is to say that it is designed for creating and conferring special statuses to people so as to alter their rights and responsibilities toward each other. To say that it is an artefact is to say that it is a tool of human creation that is designed to signal its usability to people who interact with it. This picture of law's nature is marshalled to critique theories of law that see it mainly as a product of reason or morality, understanding those theories via their conceptions of law's function. It is also used to argue against those legal positivists who see law's functions as relatively minor aspects of its nature. This method of conceptualizing law's nature helps us to explain how the law, understood as social facts, can make normative demands upon us. It also recommends a methodology for understanding law that combines elements of conceptual analysis with empirical research for uncovering the purposes to which diverse peoples put their legal activities.

Law for Society: Nature, Functions, and Limits offers an illuminating conceptual framework that looks at five basic legal instruments with which the law addresses the problems and goals of society. For any Introduction to Law course or as secondary reading in political science, criminal justice, or general studies, Law for Society breaks down the very concept of “law” to answer the questions: What is law? How does law work? What can law do and not do? The book addresses the nature of law, its problem-solving functions, and the limits on what law can accomplish.

This book seeks to contribute to a legal positivist picture of law by defending two metaphysical claims about law and investigating their methodological implications. One claim is that the law is a kind of artifact, a thoroughgoing human creation for performing certain tasks or accomplishing certain goals. That is, artifacts are generally understood in terms of their functions. When discussing artifacts, the notion of function need not be as mysterious or problematic as might be the case with biological functions. The other claim is that the law is an institution, a specific kind of artifact that creates artificial roles which allow for the establishment and manipulation of rights and duties among those subject to the institution. The methodological implication of this picture of law is that it is best understood in terms of the social functions that it performs and that the job of the legal philosopher is to investigate those functions. This position is advanced against non-positivist theories of law that nonetheless rely upon notions of law's function, and is also advanced against positivist pictures that tend to de-emphasize or overlook the central role that function must play to understand the nature of law. One key implication of this picture is that it can help explain how law might give people reasons to act beyond its use of force to do.

'Human laws must be reformulated to keep human activities in harmony with the unchanging and universal laws of nature.' This 1987 statement by the World Commission on Environment and Development has never been more relevant and urgent than it is today. Despite the many legal responses to various environmental problems, more greenhouse gases than ever before are being released into the atmosphere, biological diversity is rapidly declining and fish stocks in the oceans are dwindling. This book challenges the doctrinal construction of environmental law and presents an innovative legal approach to ecological sustainability: a rule of law for nature which guides and transcends ordinary written laws and extends fundamental principles of respect, integrity and legal security to the non-human world.
