Catastrophic risks are much greater than is commonly appreciated. Collision with an asteroid, runaway global warming, voraciously replicating nanomachines, a pandemic of gene-spliced smallpox launched by bioterrorists, and a world-ending accident in a high-energy particle accelerator, are among the possible extinction events that are sufficiently likely to warrant careful study. How should we respond to events that, for a variety of psychological and cultural reasons, we find it hard to wrap our minds around? Posner argues that realism about science and scientists, innovative applications of cost-benefit analysis, a scientifically literate legal profession, unprecedented international cooperation, and a pragmatic attitude toward civil liberties are among the keys to coping effectively with the catastrophic risks.

Richard Posner is famous throughout the legal world for his pioneering and controversial espousal of the belief that the study of law cannot be divorced from the study of economics. Here, in this volume of essays based upon his Clarendon Lectures, he explores the relationship between the legal systems of the UK and USA. The essays in this volume range widely over themes which will be familiar to many students and teachers of law. In the first essay he compares the work of the two most prominent writers on jurisprudence in the second half of this century, one English (HLA Hart) and one American (Ronald Dworkin). His controversial conclusion that trying to define "law" is futile, distracting and illustrative of the impoverishment of traditional legal theory will fascinate students of legal theory.In the second lecture he examines a number of English cases drawn primarily from the two fields in which English and American law overlap most completely - torts and contracts. Here he argues that while in general English judges use their common sense effectively to approximate the results that an economic analyst would recommend they would do even better if they were more receptive to the economic approach to the common law -- if they were, in other words, a little more like American judges.In the third lecture he examines the differences between the English and American legal systems at the administrative or operational level as distinct from the jurisprudential and doctrinal levels. The conclusions drawn from his analysis challenge traditional orthodoxy. His concluding advice to law reformers in both jurisdictions is that piecemeal reform of either system is to be avoided.In this short and highly readable work readers will find much that will delight, stimulate and challenge them.

Oliver Wendell Holmes, Jr, has been called the greatest jurist and legal scholar in the history of the English-speaking world. In this collection of his speeches, opinions and letters, Richard Posner reveals the fullness of Holmes' achievements as judge, historian, philosopher and master of English style. Thematically arranged, the volume covers a variety of subjects from aging and death to themes in politics, personalities, and law. Posner's substantial introduction firmly places this wealth of material in its biographical and historical context.

What makes a great judge? How are reputations forged? Why do some reputations endure, while others crumble? And how can we know whether a reputation is fairly deserved? In this ambitious book, Richard Posner confronts these questions in the case of Benjamin Cardozo. The result is both a revealing portrait of one of the most influential legal minds of our century and a model for a new kind of study--a balanced, objective, critical assessment of a judicial career. "The present compact and unflaggingly interesting volume ...is a full-bodied scholarly biography...It is illuminating in itself, and will serve as a significant contribution."--Paul A. Freund, New York Times Book Review

Sex, although considered by many in our culture the quintessential private activity, is blanketed by a large number and variety of laws. This text presents a concise compendium of the America's sex laws and brings together in one place, and summarizes, the laws regulating personal sexual activity. In doing so, the book reveals gaps, anachronisms, anomalies, inequalities , and irrationalities, and provides an empirical basis for studies of sexual regulation. In some states, for example, sexual relations between consenting adults of the same sex is a crime, in some states the age of consent to marriage is lower for females than for males, and in some states marital rape is not a crime. Such a mixed quilt of state laws means that a sexual practice that is perfectly legitimate in one state is illegal in another.

A Guide to America's Sex Laws is the first concise compendium of the nation's sex laws. It summarizes the laws regulating personal sexual activity, revealing gaps, anachronisms, anomalies, inequalities, and irrationalities, and providing an empirical basis for studies of sexual regulation. Judge Richard A. Posner and Katharine B. Silbaugh cover broadly defined areas of regulation, providing background and definitions and placing the laws in their historical and constitutional context. From Alabama to Wyoming, this informative and fascinating reference book will be an essential resource."It takes only a few minutes with A Guide to [America's] Sex to realize that the nation's laws governing what two consenting adults can do with one another are an odd jumble."—Eric Fidler, San Diego Commerce"Especially noteworthy is how laws governing various sexual activities vary from state to state."—Library Journal"Fascinating and often surprising facts are concisely documented and conveniently organized in A Guide."—Carlin Meyer, New York Law Journal

Are the elderly posing a threat to America's political system with their enormous clout? Are they stretching resources to the breaking point with their growing demands for care? Economist and legal scholar Richard A. Posner explodes the myth that the United States could be on the brink of gerontological disaster. This text seeks to offer fresh insight into a wide range of social and political issues relating to the elderly, such as health care, crime, social security, and discrimination. From the dread of death to the inordinate law-abidingness of the old, from their loquacity to their penny-pinching, Posner paints a surprisingly rich, revealing, and unsentimental portrait of the millions of elderly people in the United States. He explores issues such as age discrimination in employment, creativity and leadership as functions of age, and the changing social status of the elderly. Why are old people, presumably with less to lose, more unwilling to take risks than young people? Why don't the elderly in the United States command the respect and affection they once did and still do in other countries? How does aging affect driving and criminal records?And how does aging relate to creativity across different careers?

When it was first published a quarter of a century ago, Richard A. Posner's exposition and defence of an economic approach to antitrust law was a jeremiad against the intellectual disarray that then characterized the field. As other perspectives on antitrust law have fallen away, Posner's book has played a major role in transforming the field of antitrust law into a body of economically rational principles largely in accord with the ideas set forth in the first edition. Today's antitrust professionals may disagree on specific practices and rules, but most litigators, prosecutors, judges and scholars agree that the primary goal of antitrust law should be to promote economic welfare, and that economic theory should be used to determine how well business practices conform to that goal. In this thoroughly revised edition, Posner explains the economic approach to new generations of lawyers and students. He updates and amplifies his approach as it applies to the developments, both legal and economic, in the antitrust field since 1976.The "new economy", for example, has presented a host of difficult antitrust questions, and in an entirely new chapter, Posner explains how the economic approach can be applied to new industries, such as software manufacturers, Internet service providers and those that provide communications equipment and services. "The antitrust laws are here to stay", Posner writes, "and the practical question is how to administer them better - more rationally, more accurately, more expeditiously, more efficiently". This fully revised classic should continue to be a standard work in the field.

A concise, lively, and bracing exploration of an issue bedeviling our cultural landscape–plagiarism in literature, academia, music, art, and film–by one of our most influential and controversial legal scholars. Best-selling novelists J. K. Rowling and Dan Brown, popular historians Doris Kearns Goodwin and Stephen Ambrose, Harvard law professor Charles Ogletree, first novelist Kaavya Viswanathan: all have rightly or wrongly been accused of plagiarism–theft of intellectual property–provoking widespread media punditry. But what exactly is plagiarism? How has the meaning of this notoriously ambiguous term changed over time as a consequence of historical and cultural transformations? Is the practice on the rise, or just more easily detectable by technological advances? How does the current market for expressive goods inform our own understanding of plagiarism? Is there really such a thing as “cryptomnesia,” the unconscious, unintentional appropriation of another’s work? What are the mysterious motives and curious excuses of plagiarists? What forms of punishment and absolution does this “sin” elicit? What is the good in certain types of plagiarism?Provocative, insightful, and extraordinary for its clarity and forthrightness, The Little Book of Plagiarism is an analytical tour de force in small, the work of “one of the top twenty legal thinkers in America” (Legal Affairs), a distinguished jurist renowned for his adventuresome intellect and daring iconoclasm.From the Hardcover edition.

President Bill Clinton’s year of crisis, which began when his affair with Monica Lewinsky hit the front pages in January 1998, engendered a host of important questions of criminal and constitutional law, public and private morality, and political and cultural conflict.In a book written while the events of the year were unfolding, Richard Posner presents a balanced and scholarly understanding of the crisis that also has the freshness and immediacy of journalism. Posner clarifies the issues and eliminates misunderstandings concerning facts and the law that were relevant to the investigation by Independent Counsel Kenneth Starr and to the impeachment proceeding itself. He explains the legal definitions of obstruction of justice and perjury, which even many lawyers are unfamiliar with. He carefully assesses the conduct of Starr and his prosecutors, including their contacts with the lawyers for Paula Jones and their hardball tactics with Monica Lewinsky and her mother. He compares and contrasts the Clinton affair with Watergate, Iran–Contra, and the impeachment of Andrew Johnson, exploring the subtle relationship between public and private morality. And he examines the place of impeachment in the American constitutional scheme, the pros and cons of impeaching President Clinton, and the major procedural issues raised by both the impeachment in the House and the trial in the Senate. This book, reflecting the breadth of Posner’s experience and expertise, will be the essential foundation for anyone who wants to understand President Clinton’s impeachment ordeal.

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 book takes a fresh look at the most dynamic area of American law today, comprising the fields of copyright, patent, trademark, trade secrecy, publicity rights, and misappropriation. Topics range from copyright in private letters to defensive patenting of business methods, from moral rights in the visual arts to the banking of trademarks, from the impact of the court of patent appeals to the management of Mickey Mouse. The history and political science of intellectual property law, the challenge of digitization, the many statutes and judge-made doctrines, and the interplay with antitrust principles are all examined. The treatment is both positive (oriented toward understanding the law as it is) and normative (oriented to the reform of the law). Previous analyses have tended to overlook the paradox that expanding intellectual property rights can effectively reduce the amount of new intellectual property by raising the creators' input costs. Those analyses have also failed to integrate the fields of intellectual property law. They have failed as well to integrate intellectual property law with the law of physical property, overlooking the many economic and legal-doctrinal parallels.This book demonstrates the fundamental economic rationality of intellectual property law, but is sympathetic to critics who believe that in recent decades Congress and the courts have gone too far in the creation and protection of intellectual property rights.

In this timely book, the first comprehensive study of the modern American public intellectual--that individual who speaks to the public on issues of political or ideological moment--Richard Posner charts the decline of a venerable institution that included worthies from Socrates to John Dewey.With the rapid growth of the media in recent years, highly visible forums for discussion have multiplied, while greater academic specialization has yielded a growing number of narrowly trained scholars. Posner tracks these two trends to their inevitable intersection: a proliferation of modern academics commenting on topics outside their ken. The resulting scene--one of off-the-cuff pronouncements, erroneous predictions, and ignorant policy proposals--compares poorly with the performance of earlier public intellectuals, largely nonacademics whose erudition and breadth of knowledge were well suited to public discourse.Leveling a balanced attack on liberal and conservative pundits alike, Posner describes the styles and genres, constraints and incentives, of the activity of public intellectuals. He identifies a market for this activity--one with recognizable patterns and conventions but an absence of quality controls. And he offers modest proposals for improving the performance of this market--and the quality of public discussion in America today.This paperback edition contains a new preface and and a new epilogue.

The most exciting development in legal thinking since World War II has been the growth of interdisciplinary legal studies—the application of the social sciences and the humanities to law in the hope of making law less formalistic, more practical, better grounded empirically, bettered tailored to social goals. Judge Richard A. Posner has been a leader in this movement, and his new book explores its rapidly expanding frontier.The book examines five principal areas or directions of interdisciplinary study: economics, history, psychology, the epistemology of law and the empirical study of law. These approaches are seen to interpenetrate and to compose a coherent body of legal theory—a unified framework for understanding such seemingly disparate phenomena as the economics of free speech, the intellectual history of economic analysis of law, the relation between income and liberty, the law of possession, the psychology of legal decisionmaking, the role of emotion in law, and the use of citation analysis to evaluate judges and law professors. The book carries on Posner’s project of analyzing the law as an institution of social governance.

A liberal state is a representative democracy constrained by the rule of law. Richard Posner argues for a conception of the liberal state based on pragmatic theories of government. He views the actions of elected officials as guided by interests rather than by reason and the decisions of judges by discretion rather than by rules. He emphasizes the institutional and material, rather than moral and deliberative, factors in democratic decision making.Posner argues that democracy is best viewed as a competition for power by means of regular elections. Citizens should not be expected to play a significant role in making complex public policy regarding, say, taxes or missile defense. The great advantage of democracy is not that it is the rule of the wise or the good but that it enables stability and orderly succession in government and limits the tendency of rulers to enrich or empower themselves to the disadvantage of the public. Posner’s theory steers between political theorists’ concept of deliberative democracy on the left and economists’ public-choice theory on the right. It makes a significant contribution to the theory of democracy—and to the theory of law as well, by showing that the principles that inform Schumpeterian democratic theory also inform the theory and practice of adjudication. The book argues for law and democracy as twin halves of a pragmatic theory of American government.

Hailed in its first edition as an “outstanding work, as stimulating as it is intellectually distinguished” (New York Times), Law and Literature has handily lived up to the Washington Post’s prediction that the book would “remain essential reading for many years to come.” This third edition, extensively revised and enlarged, is the only comprehensive book-length treatment of the field. It continues to emphasize the essential differences between law and literature, which are rooted in the different social functions of legal and literary texts. But it also explores areas of mutual illumination and expands its range to include new topics such as the cruel and unusual punishments clause of the Constitution, illegal immigration, surveillance, global warming and bioterrorism, and plagiarism.In this edition, literary works from classics by Homer, Shakespeare, Milton, Dostoevsky, Melville, Kafka, and Camus to contemporary fiction by Tom Wolfe, Margaret Atwood, John Grisham, and Joyce Carol Oates come under Richard Posner’s scrutiny, as does the film The Matrix.The book remains the most clear, acute account of the intersection of law and literature.

A distinguished and experienced appellate court judge, Richard A. Posner offers in this new book a unique and, to orthodox legal thinkers, a startling perspective on how judges and justices decide cases. When conventional legal materials enable judges to ascertain the true facts of a case and apply clear pre-existing legal rules to them, Posner argues, they do so straightforwardly; that is the domain of legalist reasoning. However, in non-routine cases, the conventional materials run out and judges are on their own, navigating uncharted seas with equipment consisting of experience, emotions, and often unconscious beliefs. In doing so, they take on a legislative role, though one that is confined by internal and external constraints, such as professional ethics, opinions of respected colleagues, and limitations imposed by other branches of government on freewheeling judicial discretion. Occasional legislators, judges are motivated by political considerations in a broad and sometimes a narrow sense of that term. In that open area, most American judges are legal pragmatists. Legal pragmatism is forward-looking and policy-based. It focuses on the consequences of a decision in both the short and the long term, rather than on its antecedent logic. Legal pragmatism so understood is really just a form of ordinary practical reasoning, rather than some special kind of legal reasoning. Supreme Court justices are uniquely free from the constraints on ordinary judges and uniquely tempted to engage in legislative forms of adjudication. More than any other court, the Supreme Court is best understood as a political court.

Judges play a central role in the American legal system, but their behavior as decision-makers is not well understood, even among themselves. The system permits judges to be quite secretive (and most of them are), so indirect methods are required to make sense of their behavior. Here, a political scientist, an economist, and a judge work together to construct a unified theory of judicial decision-making. Using statistical methods to test hypotheses, they dispel the mystery of how judicial decisions in district courts, circuit courts, and the Supreme Court are made.The authors derive their hypotheses from a labor-market model, which allows them to consider judges as they would any other economic actors: as self-interested individuals motivated by both the pecuniary and non-pecuniary aspects of their work. In the authors' view, this model describes judicial behavior better than either the traditional “legalist” theory, which sees judges as automatons who mechanically apply the law to the facts, or the current dominant theory in political science, which exaggerates the ideological component in judicial behavior. Ideology does figure into decision-making at all levels of the federal judiciary, the authors find, but its influence is not uniform. It diminishes as one moves down the judicial hierarchy from the Supreme Court to the courts of appeals to the district courts. As The Behavior of Federal Judges demonstrates, the good news is that ideology does not extinguish the influence of other components in judicial decision-making. Federal judges are not just robots or politicians in robes.

The financial and economic crisis that began in 2008 is the most alarming of our lifetime because of the warp-speed at which it is occurring. How could it have happened, especially after all that we’ve learned from the Great Depression? Why wasn’t it anticipated so that remedial steps could be taken to avoid or mitigate it? What can be done to reverse a slide into a full-blown depression? Why have the responses to date of the government and the economics profession been so lackluster? Richard Posner presents a concise and non-technical examination of this mother of all financial disasters and of the, as yet, stumbling efforts to cope with it. No previous acquaintance on the part of the reader with macroeconomics or the theory of finance is presupposed. This is a book for intelligent generalists that will interest specialists as well.Among the facts and causes Posner identifies are: excess savings flowing in from Asia and the reckless lowering of interest rates by the Federal Reserve Board; the relation between executive compensation, short-term profit goals, and risky lending; the housing bubble fuelled by low interest rates, aggressive mortgage marketing, and loose regulations; the low savings rate of American people; and the highly leveraged balance sheets of large financial institutions.Posner analyzes the two basic remedial approaches to the crisis, which correspond to the two theories of the cause of the Great Depression: the monetarist—that the Federal Reserve Board allowed the money supply to shrink, thus failing to prevent a disastrous deflation—and the Keynesian—that the depression was the product of a credit binge in the 1920s, a stock-market crash, and the ensuing downward spiral in economic activity. Posner concludes that the pendulum swung too far and that our financial markets need to be more heavily regulated.

Following his timely and well-received A Failure of Capitalism, Richard Posner steps back to take a longer view of the continuing crisis of democratic capitalism as the American and world economies crawl gradually back from the depths to which they had fallen in the autumn of 2008 and the winter of 2009.By means of a lucid narrative of the crisis and a series of analytical chapters pinpointing critical issues of economic collapse and gradual recovery, Posner helps non-technical readers understand business-cycle and financial economics, and financial and governmental institutions, practices, and transactions, while maintaining a neutrality impossible for persons professionally committed to one theory or another. He calls for fresh thinking about the business cycle that would build on the original ideas of Keynes. Central to these ideas is that of uncertainty as opposed to risk. Risk can be quantified and measured. Uncertainty cannot, and in this lies the inherent instability of a capitalist economy.As we emerge from the financial earthquake, a deficit aftershock rumbles. It is in reference to that potential aftershock, as well as to the government’s stumbling efforts at financial regulatory reform, that Posner raises the question of the adequacy of our democratic institutions to the economic challenges heightened by the greatest economic crisis since the Great Depression. The crisis and the government’s energetic response to it have enormously increased the national debt at the same time that structural defects in the American political system may make it impossible to pay down the debt by any means other than inflation or devaluation.

Richard A. Posner is probably the leading scholar in the rapidly growing field of the economics of law; he is also an extremely lucid writer. In this book, he applies economic theory to four areas of interest to students of social and legal institutions: the theory of justice, primitive and ancient social and legal institutions, the law and economics of privacy and reputation, and the law and economics of racial discrimination.The book is designed to display the power of economics to organize and illuminate diverse fields in the study of nonmarket behavior and institutions. A central theme is the importance of uncertainty to an understanding of social and legal institutions. Another major theme is that the logic of the law, in many ways but not all, appears to be an economic one: that judges, for example, in interpreting the common law, act as if they were trying to maximize economic welfare.Part I examines the deficiencies of utilitarianism as both a positive and a normative basis of understanding law, ethics, and social institutions, and suggests in its place the economist’s concept of “wealth maximization.”Part II, an examination of the social and legal institutions of archaic societies, notably that of ancient Greece and primitive societies, argues that economic analysis holds the key to understanding such diverse features of these societies as reciprocal gift-giving, blood guilt, marriage customs, liability rules, and the prestige accorded to generosity. Many topics relevant to modern social and philosophical debate, including the origin of the state and the retributive theory of punishment, are addressed.Parts III and IV deal with more contemporary social and jurisprudential questions. Part III is an economic analysis of privacy and the statutory and common law rules that protect privacy and related interests—rules that include the tort law of privacy, assault and battery, and defamation. Finally, Part IV examines, again from an economic standpoint, the controversial areas of racial and sexual discrimination, with special reference to affirmative action. Both Part III and Part IV develop as a sub-theme the issue of proper standards of constitutional adjudication by the Supreme Court.
