Many legal theorists maintain that laws are effective because we internalize them, obeying even when not compelled to do so. In a comprehensive reassessment of the role of force in law, Frederick Schauer disagrees, demonstrating that coercion, more than internalized thinking and behaving, distinguishes law from society’s other rules.

Reinvigorating ideas from Jeremy Bentham and John Austin, and drawing on empirical research as well as philosophical analysis, Schauer presents an account of legal compliance based on sanction and compulsion, showing that law’s effectiveness depends fundamentally on its coercive potential. Law, in short, is about telling people what to do and threatening them with bad consequences if they fail to comply. Although people may sometimes obey the law out of deference to legal authority rather than fear of sanctions, Schauer challenges the assumption that legal coercion is marginal in society. Force is more pervasive than the state’s efforts to control a minority of disobedient citizens. When people believe that what they should do differs from what the law commands, compliance is less common than assumed, and the necessity of coercion becomes apparent.

Challenging prevailing modes of jurisprudential inquiry, Schauer makes clear that the question of legal force has sociological, psychological, political, and economic dimensions that transcend purely conceptual concerns. Grappling with the legal system’s dependence on force helps us understand what law is, how it operates, and how it helps organize society.

This book employs a careful, rigorous, yet lively approach to the timely question of whether we can justly generalize about members of a group on the basis of statistical tendencies of that group. For instance, should a military academy exclude women because, on average, women are more sensitive to hazing than men? Should airlines force all pilots to retire at age sixty, even though most pilots at that age have excellent vision? Can all pit bulls be banned because of the aggressive characteristics of the breed? And, most controversially, should government and law enforcement use racial and ethnic profiling as a tool to fight crime and terrorism?

Frederick Schauer strives to analyze and resolve these prickly questions. When the law “thinks like an actuary”—makes decisions about groups based on averages—the public benefit can be enormous. On the other hand, profiling and stereotyping may lead to injustice. And many stereotypes are self-fulfilling, while others are simply spurious. How, then, can we decide which stereotypes are accurate, which are distortions, which can be applied fairly, and which will result in unfair stigmatization?

These decisions must rely not only on statistical and empirical accuracy, but also on morality. Even statistically sound generalizations may sometimes have to yield to the demands of justice. But broad judgments are not always or even usually immoral, and we should not always dismiss them because of an instinctive aversion to stereotypes. As Schauer argues, there is good profiling and bad profiling. If we can effectively determine which is which, we stand to gain, not lose, a measure of justice.

“Displays a level of intellectual honesty one rarely encounters these days…This is delightful stuff.”
—Barton Swaim, Wall Street Journal

“At a time when the concept of truth itself is in trouble, this lively and accessible account provides vivid and deep analysis of the practices addressing what is reliably true in law, science, history, and ordinary life. The Proof offers both timely and enduring insights.”
—Martha Minow, former Dean of Harvard Law School

“His essential argument is that in assessing evidence, we need, first of all, to recognize that evidence comes in degrees…and that probability, the likelihood that the evidence or testimony is accurate, matters.”
—Steven Mintz, Inside Higher Education

“I would make Proof one of a handful of books that all incoming law students should read…Essential and timely.”
—Emily R. D. Murphy, Law and Society Review

In the age of fake news, trust and truth are hard to come by. Blatantly and shamelessly, public figures deceive us by abusing what sounds like evidence. To help us navigate this polarized world awash in misinformation, preeminent legal theorist Frederick Schauer proposes a much-needed corrective.

How we know what we think we know is largely a matter of how we weigh the evidence. But evidence is no simple thing. Law, science, public and private decision making—all rely on different standards of evidence. From vaccine and food safety to claims of election fraud, the reliability of experts and eyewitnesses to climate science, The Proof develops fresh insights into the challenge of reaching the truth. Schauer reveals how to reason more effectively in everyday life, shows why people often reason poorly, and makes the case that evidence is not just a matter of legal rules, it is the cornerstone of judgment.

Karl N. Llewellyn was one of the founders and major figures of legal realism, and his many keen insights have a central place in American law and legal understanding. Key to Llewellyn’s thinking was his conception of rules, put forward in his numerous writings and most famously in his often mischaracterized declaration that they are “pretty playthings.” Previously unpublished, The Theory of Rules is the most cogent presentation of his profound and insightful thinking about the life of rules.

This book frames the development of Llewellyn’s thinking and describes the difference between what rules literally prescribe and what is actually done, with the gap explained by a complex array of practices, conventions, professional skills, and idiosyncrasies, most of which are devoted to achieving a law’s larger purpose rather than merely following the letter of a particular rule. Edited, annotated, and with an extensive analytic introduction by leading contemporary legal scholar Frederick Schauer, this rediscovered work contains material not found elsewhere in Llewellyn’s writings and will prove a valuable contribution to the existing literature on legal realism.

This primer on legal reasoning is aimed at law students and upper-level undergraduates. But it is also an original exposition of basic legal concepts that scholars and lawyers will find stimulating. It covers such topics as rules, precedent, authority, analogical reasoning, the common law, statutory interpretation, legal realism, judicial opinions, legal facts, and burden of proof.

In addressing the question whether legal reasoning is distinctive, Frederick Schauer emphasizes the formality and rule-dependence of law. When taking the words of a statute seriously, when following a rule even when it does not produce the best result, when treating the fact of a past decision as a reason for making the same decision again, or when relying on authoritative sources, the law embodies values other than simply that of making the best decision for the particular occasion or dispute. In thus pursuing goals of stability, predictability, and constraint on the idiosyncrasies of individual decision-makers, the law employs forms of reasoning that may not be unique to it but are far more dominant in legal decision-making than elsewhere.

Schauer’s analysis of what makes legal reasoning special will be a valuable guide for students while also presenting a challenge to a wide range of current academic theories.
