When people in a relationship disagree about their obligations to each other, they need to rely on a method of reasoning that allows the relationship to flourish while advancing each person's private projects. This book presents a method of reasoning that reflects how people reason through disagreements and how courts create doctrine by reasoning about the obligations arising from the relationship. Built on the ideal of the other-regarding person, Contract Law and Social Morality displays a method of reasoning that allows one person to integrate their personal interests with the interests of another, determining how divergent interests can be balanced against each other. Called values-balancing reasoning, this methodology makes transparent the values at stake in a disagreement, and provides a neutral and objective way to identify and evaluate the trade-offs that are required if the relationship is to be sustained or terminated justly.

The Dignity of Commerce is a rigorous and novel exploration of moral justification of contract law through how it fosters well-functioning markets. Nathan B. Oman demonstrates how contract law deals overwhelmingly with the matters of commercial exchange, and how commerce in turn breeds habits of mind, or virtues, that support a liberal society. He also shows how markets provide a framework for peaceful cooperation across the fault lines of race, culture, religion, and politics that outdo even democratic political institutions. The Dignity of Commerce is ambitious in its aims and its conclusions and the implications are powerful. It is sure to elicit a serious discussion at the very heart of one of the most central areas of legal studies, and Nathan B. Oman has provided a clear, engaging, and comprehensive vehicle to get the discussion started.

War by Agreement presents a new theory on the ethics of war. It shows that wars can be morally justified at both the ad bellum level (the political decision to go to war) and the in bello level (its actual conduct by the military)by accepting a contractarian account of the rules governing war. According to this account, the rules of war are anchored in a mutually beneficial and fair agreement between the relevant players - the purpose of which is to promote peace and to reduce the horrors of war. The book relies on the long social contract tradition and illustrates its fruitfulness in understanding and developing the morality and the law of war.

In recent years there has been a revival of interest in the philosophical study of contract law. In 1981 Charles Fried claimed that contract law is based on the philosophy of promise and this has generated what is today known as 'the contract and promise debate'. Cutting to the heart of contemporary discussions, this volume brings together leading philosophers, legal theorists, and contract lawyers to debate the philosophical foundations of this area of law. Divided into two parts, the first explores general themes in the contract theory literature, including the philosophy of promising, the nature of contractual obligation, economic accounts of contract law, and the relationship between contract law and moral values such as personal autonomy and distributive justice. The second part uses these philosophical ideas to make progress in doctrinal debates, relating for example to contract interpretation, unfair terms, good faith, vitiating factors, and remedies. Together, the essays provide a picture of the current state of research in this revitalized area of law, and pave the way for future study and debate.

Containing the bulk of Morris Cohen's writings on the philosophy of law, this collection of essays features articles originally published in popular periodicals and law reviews during the early decades of this century. In his introduction to the Social and Moral Thought edition, Harry N. Rosenfield reviews Cohen's contributions to the philosophy of law and emphasizes Cohen's enormous influence, as a legal philosopher, on American law.

In "Theologians and Contract Law," Wim Decock offers an account of the moral roots of modern contract law. He explains why theologians in the sixteenth and seventeenth centuries built a systematic contract law around the principles of freedom and fairness.

“One of the most important contributions to the field of contract theory—if not the most important—in the past 25 years.” —Stephen A. Smith, McGill University Can we account for contract law on a moral basis that is acceptable from the standpoint of liberal justice? To answer this question, Peter Benson develops a theory of contract that is completely independent of—and arguably superior to—long-dominant views, which take contract law to be justified on the basis of economics or promissory morality. Through a detailed analysis of contract principles and doctrines, Benson brings out the specific normative conception underpinning the whole of contract law. Contract, he argues, is best explained as a transfer of rights, which is complete at the moment of agreement and is governed by a definite conception of justice—justice in transactions. Benson’s analysis provides what John Rawls called a public basis of justification, which is as essential to the liberal legitimacy of contract as to any other form of coercive law. The argument of Justice in Transactions is expressly complementary to Rawls’s, presenting an original justification designed specifically for transactions, as distinguished from the background institutions to which Rawls’s own theory applies. The result is a field-defining work offering a comprehensive theory of contract law. Benson shows that contract law is both justified in its own right and fully congruent with other domains—moral, economic, and political—of liberal society.
