When people of good faith and sound mind disagree deeply about moral, religious, and other philosophical matters, how can we justify political institutions to all of them? The idea of public reason-of a shared public standard, despite disagreement-arose in the seventeenth and eighteenth centuries in the work of Hobbes, Locke, Rousseau, and Kant. At a time when John Rawls' influential theory of public reason has come under fire but its core idea remains attractive to many, it is important not to lose sight of earlier philosophers' answers to the problem of private conflict through public reason. The distinctive selections from the great social contract theorists in this volume emphasize the pervasive theme of intractable disagreement and the need for public justification. New essays by leading scholars then put the historical work in context and provide a focus of debate and discussion. They also explore how the search for public reason has informed a wider body of modern political theory-in the work of Hume, Hegel, Bentham, and Mill-sometimes in surprising ways. The idea of public reason is revealed as an overarching theme in modern political philosophy-one very much needed today.

The study of the physical world had its origins in philosophy, and, two-and-one-half millennia later, the scientific advances of the twentieth century are bringing the two fields closer together again. So argues Lawrence Sklar in this brilliant new text on the philosophy of physics.Aimed at students of both disciplines, Philosophy of Physics is a broad overview of the problems of contemporary philosophy of physics that readers of all levels of sophistication should find accessible and engaging. Professor Sklar's talent for clarity and accuracy is on display throughout as he guides students through the key problems: the nature of space and time, the problems of probability and irreversibility in statistical mechanics, and, of course, the many notorious problems raised by quantum mechanics.Integrated by the theme of the interconnectedness of philosophy and science, and linked by many references to the history of both disciplines, Philosophy of Physics is always clear, while remaining faithful to the complexity and integrity of the issues. It will take its place as a classic text in a field of fundamental intellectual importance.

An updated and expanded edition of the classic introduction to PPE-philosophy, politics, and economics-coauthored by one of the field's pioneers Philosophy, Politics, and Economics offers a complete introduction to the fundamental tools and concepts of analysis that PPE students need to study social and political issues. This fully updated and expanded edition examines the core methodologies of rational choice, strategic analysis, norms, and collective choice that serve as the bedrocks of political philosophy and the social sciences. The textbook is ideal for advanced undergraduates, graduate students, and nonspecialists looking to familiarize themselves with PPE's approaches. Starting with individual choice, the book develops an account of rationality to introduce readers to decision theory, utility theory, and concepts of welfare economics and consumer choice theory. It moves to strategic choice in game theory to explore such issues as bargaining theory, repeated games, and evolutionary game theory. The text also considers how social norms can be understood, observed, and measured. Concluding chapters address collective choice, social choice theory and democracy, and public choice theory's connections to voters, representatives, and institutions. Rigorous and comprehensive, Philosophy, Politics, and Economics continues to be an essential text for this popular and burgeoning field. The only book that covers the entirety of PPE methods A rigorous, nontechnical introduction to decision theory, game theory, and positive political theory A philosophical introduction to rational choice theory in the social sciences

Gerald Gaus was one of the leading liberal theorists of the late twentieth and early twenty-first centuries. He developed a pioneering defence of the liberal order based on its unique capacity to handle diversity and disagreement, and he presses the liberal tradition towards a principled openness to pluralism and diversity. This book brings together Gaus's most seminal and creative essays in a single volume for the first time. It also covers a broad span of his career, including essays published shortly before his death, and topics including reasonable pluralism, moral rights, public reason, and the redistributive state. The volume makes accessible the work of one of the most important recent liberal theorists. Many readers will find it of value, especially those in political philosophy, political science, and economics.

This volume brings together distinguished philosophers with interdisciplinary expertise to show how the resources of philosophy can be employed in the tasks of evaluating economics and fostering policy debates. Contributors offer analyses of basic ideas in economics, such as the notion of efficiency, "economic man," incentives, self-interest, and utility maximization. They discuss key concepts in political theory such as desert, compensation, autonomy, equality, consent or fairness. The book then offers examples of how philosophical resources can be applied to specific, timely debates, such as discrimination, affirmative action, and ethical considerations in Social Security. These applications demonstrate how philosophy, politics, and economics can be fruitfully combined, while the more theoretical chapters clarify fundamental relationships across these related disciplines. Ultimately, the text guides students and scholars in expanding their perspectives as they approach the necessarily complex research questions of today and tomorrow.

In this innovative and important work, Gerald Gaus advances a revised, and more realistic, account of public reason liberalism, showing how, in the midst of fundamental disagreement about values and moral beliefs, we can achieve a moral and political order that treats all as free and equal moral persons. The first part of this work analyzes social morality as a system of authoritative moral rules. Drawing on an earlier generation of moral philosophers such as Kurt Baier and Peter Strawson as well as current work in the social sciences, Gaus argues that our social morality is an evolved social fact, which is the necessary foundation of a mutually beneficial social order. The second part considers how this system of social moral authority can be justified to all moral persons. Drawing on the tools of game theory, social choice theory, experimental psychology, and evolutionary theory, Gaus shows how a free society can secure a moral equilibrium that is endorsed by all, and how a just state respects, and develops, such an equilibrium.

"Political Concepts and Political Theories" introduces political theory by focusing on enduring disputes about the nature of freedom, power, equality, justice, democracy, and authority. The first part of the book examines the nature of these disputes. It clarifies what we are disagreeing about when we offer different interpretations of political concepts, and why our disagreements about them are so difficult to resolve. Providing accessible accounts of the views of Plato, Wittgenstein, and recent theorists such as Gallie, Gaus argues that our interpretation of a political concept such as liberty is not freestanding but linked to our understandings of power, equality, justice, democracy, and other values. To understand a particular political concept, Gaus argues, we must place it in a political theory, which constitutes a system of such concepts. The second part of the book examines the ways in which liberal, socialist, and conservative thinkers have interpreted these enduring political concepts. Gaus considers a wide range of classical and contemporary advocates of these theories."Political Concepts and Political Theories" presents in an accessible way an innovative approach to the analysis of political concepts and the study of political theory. As such, it will be of interest both to those looking at political concepts and political theories for the first time, as well as to scholars who have already examined these issues.

In his provocative new book, The Tyranny of the Ideal, Gerald Gaus lays out a vision for how we should theorize about justice in a diverse society. Gaus shows how free and equal people, faced with intractable struggles and irreconcilable conflicts, might share a common moral life shaped by a just framework. He argues that if we are to take diversity seriously and if moral inquiry is sincere about shaping the world, then the pursuit of idealized and perfect theories of justice--essentially, the entire production of theories of justice that has dominated political philosophy for the past forty years--needs to change. Drawing on recent work in social science and philosophy, Gaus points to an important paradox: only those in a heterogeneous society--with its various religious, moral, and political perspectives--have a reasonable hope of understanding what an ideally just society would be like. However, due to its very nature, this world could never be collectively devoted to any single ideal. Gaus defends the moral constitution of this pluralistic, open society, where the very clash and disagreement of ideals spurs all to better understand what their personal ideals of justice happen to be. Presenting an original framework for how we should think about morality, The Tyranny of the Ideal rigorously analyzes a theory of ideal justice more suitable for contemporary times.

A mere two decades ago it was widely assumed that liberal democracy and the Open Society it created had decisively won their century-long struggle against authoritarianism. Although subsequent events have shocked many, F.A. Hayek would not have been surprised that we are in many ways disoriented by the society we have created. As he understood it, the Open Society was a precarious achievement in many ways at odds with our deepest moral sentiments. His path-breaking analyses argued that the Open Society runs against our evolved attraction to "tribalism" that the Open Society is too complex for moral justification; and that its self-organized complexity defies attempts at democratic governance. In his final, wide-ranging book, Gerald Gaus critically reexamines Hayek's analyses. Drawing on diverse work in social and moral science, Gaus argues that Hayek's program was manifestly prescient and strikingly sophisticated, always identifying real and pressing problems. Yet, Gaus maintains, Hayek underestimated the resources of human morality and the Open Society to cope with the challenges he perceived. Gaus marshals formal models and empirical evidence to show that our Open Society is grounded on moral foundations of human cooperation originating in our distant evolutionary past, but has built upon them a complex and diverse society that requires us to rethink both the nature of moral justification and the meaning of democratic self-governance. In these fearful, angry and inwardly-looking times, when political philosophy has itself become a hostile exchange between ideological camps, The Open Society and Its Complexities shows how moral and ideological diversity, so far from being the enemy of a free and open society, can be its foundation.
