This book examines the issue of rational cooperation, especially cooperation between people with conflicting moral commitments. The first part considers how the two main aspects of cooperation - the choice by a group of a particular cooperative scheme and the decision by each member to contribute to that scheme - can be understood as guided by reason. The second part explores how the activity of reasoning itself can take a cooperative form. The book is distinctive in offering an account of what people can accomplish by reasoning together, of the role of deliberation in democratic decision making, and of the negotiation of the proper use of concepts. Presenting for the first time a detailed analysis of the general problem of cooperation and collective reasoning between people with different moral commitments, this book will be of particular interest to philosophers of the social sciences and to students in political science, sociology and economics.

We all know, or think we know, what it means to say that something is 'reasonable' or 'fair', but what exactly are these concepts and how have they evolved and changed over the course of history? In this book, Christopher McMahon explores reasonableness, fairness, and justice as central concepts of the morality of reciprocal concern. He argues that the basis of this morality evolves as history unfolds, so that forms of interaction that might have been morally acceptable in the past are judged unacceptable today. The first part of his study examines the notions of reasonableness and fairness as they are employed in ordinary practical thought, and the second part develops a constructivist theory to explain why and how this part of morality can undergo historical development without arriving at any final form. His book will interest scholars of ethics, political theory, and the history of ideas.

This book is a collection of essays on various problems arising in connection with John Rawls's theory of justice. Its focus is the method of wide reflective equilibrium. The first half of the book begins with Daniels's well-known essay "Wide Reflective Equilibrium and Theory Acceptance in Ethics" and ends with an excellent discussion of the role of reflective equilibrium in Rawls's Political Liberalism. The essays in the second part discuss justice in health care. They are of interest in their own right, and also as illustrating Daniels's view that for those practicing the method of reflective equilibrium, applied moral philosophy is integral to the process of moral theorizing. Daniels says that the essays do not constitute a systematic treatment of wide reflective equilibrium. But they display a much higher degree of thematic coherence than is usual in a collection, and they read much like the chapters of a monograph.
