Judge Richard Posner is one of the great legal minds of our age, on par with such generation-defining judges as Holmes, Hand, and Friendly. A judge on the U.S. Court of Appeals for the Seventh Circuit and the principal exponent of the enormously influential law and economics movement, he writes provocative books as a public intellectual, receives frequent media attention, and has been at the center of some very high-profile legal spats. He is also a member of an increasingly rare breed-judges who write their own opinions rather than delegating the work to clerks-and therefore we have unusually direct access to the workings of his mind and judicial philosophy. Now, for the first time, this fascinating figure receives a full-length biographical treatment. In Richard Posner, William Domnarski examines the life experience, personality, academic career, jurisprudence, and professional relationships of his subject with depth and clarity. Domnarski has had access to Posner himself and to Posner's extensive archive at the University of Chicago. In addition, Domnarski was able to interview and correspond with more than two hundred people Posner has known, worked with, or gone to school with over the course of his career, from grade school to the present day. The list includes among others members of the Harvard Law Review, colleagues at the University of Chicago, former law clerks over Posner's more than thirty years on the United States Court of Appeals for the Seventh Circuit, and even other judges from that court. Richard Posner is a comprehensive and accessible account of a unique judge who, despite never having sat on the Supreme Court, has nevertheless dominated the way law is understood in contemporary America.

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.

In Reflections on Judging, Richard Posner distills the experience of his thirty-one years as a judge of the United States Court of Appeals for the Seventh Circuit. Surveying how the judiciary has changed since his 1981 appointment, he engages the issues at stake today, suggesting how lawyers should argue cases and judges decide them, how trials can be improved, and, most urgently, how to cope with the dizzying pace of technological advance that makes litigation ever more challenging to judges and lawyers. For Posner, legal formalism presents one of the main obstacles to tackling these problems. Formalist judges--most notably Justice Antonin Scalia--needlessly complicate the legal process by advocating "canons of constructions" (principles for interpreting statutes and the Constitution) that are confusing and self-contradictory. Posner calls instead for a renewed commitment to legal realism, whereby a good judge gathers facts, carefully considers context, and comes to a sensible conclusion that avoids inflicting collateral damage on other areas of the law. This, Posner believes, was the approach of the jurists he most admires and seeks to emulate: Oliver Wendell Holmes, Louis Brandeis, Benjamin Cardozo, Learned Hand, Robert Jackson, and Henry Friendly, and it is an approach that can best resolve our twenty-first-century legal disputes.

Judges and legal scholars talk past one another, if they have any conversation at all. Academics criticize judicial decisions in theoretical terms, which leads many judges to dismiss academic discourse as divorced from reality. Richard Posner reflects on the causes and consequences of this widening gap and what can be done to close it.

This text for students of law and economics concentrates on the progress of scholarship in the field. Concrete applications are emphasized over abstract theory in the book.

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.

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.
