In Minimal Rationality, Christopher Cherniak boldly challenges the myth of Man the the Rational Animal and the central role that the "perfectly rational...

The essays in this volume consider the question of whether the self is a unity or whether it should be conceived without metaphor as divided - as a 'multiple self'. The issue is a central one for several disciplines. It bears directly on the account of rationality and the explanation of individual decision-making and behaviour. Is the hypothesis of a multiple self required to deal with the problems of self-deception and weakness of will; and can the conceptual tools developed in (...) the study of interpersonal conflict be applied to the analysis of intra-personal struggle? Most of the essays, by a number of leading philosophers, psychologists and economists, appear here for the first time. They bring out the interdisciplinary importance of the question, and will interest readers in all those areas. The volume will also usefully supplement The Foundations of Social Choice Theory, edited by Jon Elster and Aanund Hylland, which appears in the same series and is also concerned with the foundations of rationality.

Sour Grapes aims to subvert orthodox theories of rational choice through the study of forms of irrationality. Dr Elster begins with an analysis of the notation of rationality, to provide the background and terms for the subsequent discussions, which cover irrational behaviour, irrational desires and irrational belief. These essays continue and complement the arguments of Jon Elster's earlier book, Ulysses and the Sirens. That was published to wide acclaim, and Dr Elster shows the same versatility here in drawing on philosophy, (...) political and social theory, decision-theory, economics and psychology, as well as history and literature.

This article described three heuristics that are employed in making judgements under uncertainty: representativeness, which is usually employed when people are asked to judge the probability that an object or event A belongs to class or process B; availability of instances or scenarios, which is often employed when people are asked to assess the frequency of a class or the plausibility of a particular development; and adjustment from an anchor, which is usually employed in numerical prediction when a relevant value (...) is available. These heuristics are highly economical and usually effective, but they lead to systematic and predictable errors. A better understanding of these heuristics and of the biases to which they lead could improve judgements and decisions in situations of uncertainty. (shrink)

In fact, it requires two major social institutions--morality and government--working in a coordinated fashion to do so. This is one of the main themes of Hobbes's philosophy that will be developed in this book.

The study of intrapersonal economic relations, or economics , is still at the programmatic stage. There is no generally accepted paradigm, or even as well-defined set of problems that constitute it as a subdiscipline within economics. Some questions are, however, emerging as foci of interest for a small but increasing number of writers, not just in economics, but also in psychology and philosophy. The writings of Thomas Schelling on self-management, of George Ainslie on self-control, and of Derik Parfit on personal (...) identity testify to this convergence. (shrink)

Is morality rational? In this book Gauthier argues that moral principles are principles of rational choice. He proposes a principle whereby choice is made on an agreed basis of cooperation, rather than according to what would give an individual the greatest expectation of value. He shows that such a principle not only ensures mutual benefit and fairness, thus satisfying the standards of morality, but also that each person may actually expect greater utility by adhering to morality, even though the choice (...) did not have that end primarily in view. In resolving what may appear to be a paradox, the author establishes morals on the firm foundation of reason. Gauthier's argument includes an account of value, linking it to preference and utility; a discussion of the curcumstances in which morality is unnecessary; and an application of morals by agreement to relations between peoples at different levels of development and different generations. Finally, he reflects on the assumptions about individuality and community made by his account of rationality and morality. (shrink)

What system of morals should rational people select as the best for society? Using a contemporary psychological theory of action and of motivation, Richard Brandt's Oxford lectures argue that the purpose of living should be to strive for the greatest good for the largest number of people. Brandt's discussions range from the concept of welfare to conflict between utilitarian moral codes and the dictates of self-interest.

This 1987 book offers a critique of the liberal theory of the state, focusing on a detailed study of cooperation in the absence of the state and of other kinds of coercion. The discussion includes an analysis of collective action and of the Prisoners' Dilemma supergame. It is a revised and expanded edition of the author's classic work of rational choice theory Anarchy and Cooperation, originally published with John Wiley in 1976. The analysis has been recast and developed here to (...) make it more accessible to non-mathematical readers and to provide a more comprehensive and self-contained treatment of the theory of collective action. The book will be of interest to a range of readers in political and social philosophy and in economics. (shrink)

The 'Evolution of Cooperation' addresses a simple yet age-old question; If living things evolve through competition, how can cooperation ever emerge? Despite the abundant evidence of cooperation all around us, there existed no purely naturalistic answer to this question until 1979, when Robert Axelrod famously ran a computer tournament featuring a standard game-theory exercise called The Prisoner's Dilemma. To everyone's surprise, the program that won the tournament, named Tit for Tat, was not only the simplest but the most "cooperative" entrant. (...) This unexpected victory proved that cooperation - one might even say altruism - is mathematically possible and therefore needs no hidden hand or divine agent to create and sustain it. A great roadblock to the understanding of all sorts of behavior was at last removed. The updated edition includes an extensive new chapter on cooperation in cancer cells and among terrorist organizations. (shrink)

It is a commonplace that in making decisions agents often have to juggle competing values, and that no choice will maximise satisfaction of them all. However, the prevailing account of these cases assumes that there is always a single ranking of the agent's values, and therefore no unresolvable conflict between them. Isaac Levi denies this assumption, arguing that agents often must choose without having balanced their different values and that to be rational, an act does not have to be optimal, (...) only what Levi terms 'admissible'. This book explores the consequences of denying the assumption and develops a general approach to decision-making under unresolved conflict. Professor Levi discusses conflicts of value in several domains - those arising in moral dilemmas, the drawing of scientific inferences, decisions taken under uncertainty, and in social choice. In each of these he adapts his theoretical framework, showing how conflict may often be reduced though not always altogether eliminated. (shrink)

FEW HEROES LOWER their sights in the prime of their lives; triumph leads inexorably on, often to destruction. Alexander wept because he had no new worlds to conquer; Napoleon, overextended, sealed his doom in the depth of a Russian winter. But Charles Darwin did not follow the Origin of Species (1859) with a general defense of natural selection or with its evident extension to human evolution (he waited until 1871 to publish The Descent of Man). Instead, he wrote his most (...) obscure work, a book entitled: On the Various Contrivances by Which British and Foreign Orchids Are Fertilized by Insects (1862). (shrink)

Thomas Hobbes took a new look at the ways in which society should function, and he ended up formulating the concept of political science. His crowning achievement, Leviathan, remains among the greatest works in the history of ideas. Written during a moment in English history when the political and social structures as well as methods of science were in flux and open to interpretation, Leviathan played an essential role in the development of the modern world. This edition of Hobbes' landmark (...) work is based on the original text. It incorporates the author's own corrections and retains the period spelling and punctuation, offering both flavorful authenticity and the utmost clarity of expression. (shrink)
