Extended Rationality

Extended Rationality provides a novel account of the structure of epistemic justification. Its central claim builds upon Wittgenstein's idea that epistemic justifications hinge on some basic assumptions and that epistemic rationality extends to these very hinges. It exploits these ideas to address problems such as scepticism and relativism.

Groups of people perform acts that are subject to standards of rationality. The book's theory of collective rationality explains how to evaluate collective acts. The people engaged in a game of strategy collectively produce an outcome, and the theory reveals what makes some outcomes solutions. It generates new equilibrium standards for solutions to cooperative games.

Human actions unfold over time, in pursuit of ends that are not fully specified in advance. Rational Powers in Action locates these features of the human condition at the heart of a new theory of instrumental rationality. Where many theories of rational agency focus on instantaneous choices between sharply defined outcomes, treating the temporally extended and partially open-ended character of action as an afterthought, this book argues that the deep structure of instrumental rationality can only be understood if we see how it governs the pursuit of long-term, indeterminate ends. These are ends that cannot be realized through a single momentary action, and whose content leaves partly open what counts as realizing the end. Sergio Tenenbaum argues that we need to focus on temporal duration and the indeterminacy of ends in intentional action, even to explain the rational governance of relatively simple actions. Theories of moment-by-moment preference maximization, or indeed any understanding of instrumental rationality on the basis of momentary mental items, cannot capture the fundamental structure of our instrumentally rational capacities. Tenenbaum provides a new theory of instrumental rationality as rationality in action.

Marking a significant departure from most scholarship on Hobbes, this book offers new interpretations of his theories of freedom, agency, rationality, morality, psychology, and politics. Hobbes's arguments concerning many different aspects of civil society and human psychology are brought together to provide a comprehensive theory of agency. Hobbes's theory of freedom is demonstrated to be considerably more complicated than previously thought, revealing a concern with both "internal" and "external" conditions of action. On close examination Hobbes can be seen to move beyond his limited definition of negative liberty and to champion autonomous rational action. Throughout, the book evaluates the relevance of this reformulation for contemporary debates in political philosophy.

I would like to use this preface to thank some persons and institutions which have been important during the various stages of writing this book. First of all, I am grateful to Kluwer Academic Publishers for giving me the opportunity to write this book. I started writing the book in 1998 while I was working at the Departament d'Economia i d'Historia Economica at Universidad Autonoma de Barcelona, and continued the writing job from september 1998 to september 2000 at the Departamento de Economfa at Universidad Carlos III de Madrid. The book has been completed while I was visiting the Department of Quantitative Economics at the University of Maastricht from october 2000 to august 2001. I wish to thank these three departments for their hospitality. The book has improved substantially by comments and critique from the following persons who have read parts of the manuscript: Geir Asheim, Eric van Damme, Janos Flesch, Mari-Angeles de Frutos, Diego Moreno, Hans Peters, Antonio Romero and Dries Vermeulen. I should also mention my discussions with Peter Wakker about the decision-theoretic foundations of noncooperative game theory, which have had an important impact on various parts of the book. Finally, I wish to express my warmest gratitude to my parents, my brother and my sister, and, last but not least, to Cati, to whom I dedicate this book.

The connection between economics and ethics is as old as economics itself, and central to both disciplines. The essays included in the present volume provide an analysis of the connections between ethics and economics as viewed from several different - oft
