In this book, one of our country’s most distinguished scholar-judges shares with us his vision of the law. For the past two thousand years, the philosophy of law has been dominated by two rival doctrines. One contends that law is more than politics and yields, in the hands of skillful judges, correct answers to even the most difficult legal questions; the other contends that law is politics through and through and that judges wield essentially arbitrary powers. Rejecting these doctrines as too metaphysical in the first instance and too nihilistic in the second, Richard Posner argues for a pragmatic jurisprudence, one that eschews formalism in favor of the factual and the empirical. Laws, he argues, are not abstract, sacred entities, but socially determined goads for shaping behavior to conform with society’s values. Examining how judges go about making difficult decisions, Posner argues that they cannot rely on either logic or science, but must fall back on a grab bag of informal methods of reasoning that owe less than one might think to legal training and experience. Indeed, he reminds us, the greatest figures in American law have transcended the traditional conceptions of the lawyer’s craft. Robert Jackson did not attend law school and Benjamin Cardozo left before getting a degree. Holmes was neither the most successful of lawyers nor the most lawyerly of judges. Citing these examples, Posner makes a plea for a law that frees itself from excessive insularity and takes all knowledge, practical and theoretical, as grist for its mill. The pragmatism that Posner espouses implies looking at problems concretely, experimentally, without illusions, with an emphasis on keeping diverse paths of inquiry open, and, above all, with the insistence that social thought and action be evaluated as instruments to desired human goals rather than as ends in themselves. In making his arguments, he discusses notable figures in jurisprudence from Antigone to Ronald Dworkin as well as recent movements ranging from law and economics to civic republicanism, and feminism to libertarianism. All are subjected to Posner’s stringent analysis in a fresh and candid examination of some of the deepest problems presented by the enterprise of law.

In modern times the idea of the objectivity of law has been undermined by skepticism about legal institutions, disbelief in ideals of unbiased evaluation, and a conviction that language is indeterminate. Greenawalt here considers the validity of such skepticism, examining such questions as: whether the law as it exists provides determinate answers to legal problems; whether the law should treat people in an "objective way," according to abstract rules, general categories, and external consequences; and how far the law is anchored in something external to itself, such as social morality, political justice, or economic efficiency. In the process he illuminates the development of jurisprudence in the English-speaking world over the last fifty years, assessing the contributions of many important movements.

Ambitious legal thinkers have become mesmerized by moral philosophy, believing that great figures in the philosophical tradition hold the keys to understanding and improving law and justice and even to resolving the most contentious issues of constitutional law. They are wrong, contends Richard Posner in this book. Posner characterizes the current preoccupation with moral and constitutional theory as the latest form of legal mystification--an evasion of the real need of American law, which is for a greater understanding of the social, economic, and political facts out of which great legal controversies arise. In pursuit of that understanding, Posner advocates a rebuilding of the law on the pragmatic basis of open-minded and systematic empirical inquiry and the rejection of cant and nostalgia--the true professionalism foreseen by Oliver Wendell Holmes a century ago. A bracing book that pulls no punches and leaves no pieties unpunctured or sacred cows unkicked, The Problematics of Moral and Legal Theory offers a sweeping tour of the current scene in legal studies--and a hopeful prospect for its future.

This law school casebook starts from the premise that cyberlaw is not simply a set of legal rules governing online interaction, but a lens through which to re-examine general problems of policy, jurisprudence, and culture. The book goes beyond simply plugging Internet-related cases into a series of doctrinal categories, instead emphasizing conceptual issues that extend across the spectrum of cyberspace legal dilemmas. While the book addresses all of the "traditional" subject matter areas of cyberlaw, it asks readers to consider both how traditional legal doctrines can be applied to cyberspace conduct, and how the special problems encountered in that application can teach us something about those traditional legal doctrines. The fifth edition has been updated, shortened, and reconceptualized to make the book even more effective as a teaching tool and to illuminate new debates at the heart of this evolving field. The book groups the material into units addressing the who, how, and what of governance/regulation--fundamental questions that pertain to any legal system, in cyberspace or elsewhere. The fifth edition also includes updated treatment throughout, as well as a more stream-lined approach that should make an already effective casebook even more unified and teachable.

What is law? This question has preoccupied philosophers from Plato to Thomas Hobbes to H. L. A. Hart. Yet many others find it perplexing. How could we possibly know how to answer such an abstract question? And what would be the point of doing so? In Legality, Scott Shapiro argues that the question is not only meaningful but vitally important. In fact, many of the most pressing puzzles that lawyers confront—including who has legal authority over us and how we should interpret constitutions, statutes, and cases—will remain elusive until this grand philosophical question is resolved. Shapiro draws on recent work in the philosophy of action to develop an original and compelling answer to this age-old question. Breaking with a long tradition in jurisprudence, he argues that the law cannot be understood simply in terms of rules. Legal systems are best understood as highly complex and sophisticated tools for creating and applying plans. Shifting the focus of jurisprudence in this way—from rules to plans—not only resolves many of the most vexing puzzles about the nature of law but has profound implications for legal practice as well. Written in clear, jargon-free language, and presupposing no legal or philosophical background, Legality is both a groundbreaking new theory of law and an excellent introduction to and defense of classical jurisprudence.

This is a brief introduction to the major issues in legal philosophy, intended for use as a secondary text in law schools, and in graduate and undergraduate courses in philosophy of law, jurisprudence and legal issues.

In this volume, Julie Klein provides the first comprehensive study of the modern concept of interdisciplinarity, supplementing her discussion with the most complete bibliography yet compiled on the subject. Spanning the social sciences, natural sciences, humanities, and professions, her study is a synthesis of existing scholarship on interdisciplinary research, education and health care. Klein argues that any interdisciplinary activity embodies a complex network of historical, social, psychological, political, economic, philosophical, and intellectual factors. Whether the context is a short-ranged instrumentality or a long-range reconceptualization of the way we know and learn, the concept of interdisciplinarity is an important means of solving problems and answering questions that cannot be satisfactorily addressed using singular methods or approaches.
