Edna Ullmann-Margalit provides an original account of the emergence of norms. Her main thesis is that certain types of norms are possible solutions to problems posed by certain types of social interaction situations. She presents illuminating discussions of Prisoners' Dilemma, co-ordination, and inequality situations.

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)

There has been a persistent tendency to identify what is called “the freerider problem” in the production of collective goods with the prisoner's dilemma. However, in this article I want to challenge that identification by presenting an analysis of what are in fact a variety of collective action problems in the production of collective goods. My strategy is not to consult any intuitions about what the free-rider problem is; rather I will be looking at the problematic game-theoretic structures of various (...) situations associated with the production of different types of collective goods, thereby showing what sorts of difficulties a community concerned with their voluntary production would face. I call all of these dilemmas free-rider problems because in all of them certain individuals find it rational to take advantage of others' willingness to contribute to the good in a way that threatens its production. Some readers may feel that the term ‘free-rider problem’ is so identified with the prisoner's dilemma that my extension of the term in this way “jars”; if so, I invite them to coin another word for the larger phenomenon. My aim is not to engage in linguistic analysis but to attempt at least a partial analysis of the complicated structure of collective good production. (shrink)

A key to modern studies of 18th century Western philosophy, the Treatise considers numerous classic philosophical issues, including causation, existence, freedom and necessity and morality. This abridged edition has an introduction which explain's Hume's thought and places it in the context of its times.

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)

Unpopular in its day, David Hume's sprawling, three-volume A Treatise of Human Nature (1739-40) has withstood the test of time and had enormous impact on subsequent philosophical thought. Hume's comprehensive effort to form an observationally grounded study of human nature employs John Locke's empiric principles to construct a theory of knowledge from which to evaluate metaphysical ideas. A key to modern studies of eighteenth-century Western philosophy, the Treatise considers numerous classic philosophical issues, including causation, existence, freedom and necessity, and morality. (...) Unabridged republication of the edition originally published by Oxford at the Clarendon Press, London, 1888. Index. Appendix. (shrink)

A Treatise of Human Nature, David Hume's comprehensive attempt to base philosophy on a new, observationally grounded study of human nature, is one of the most important texts in Western philosophy. It is also the focal point of current attempts to understand 18th-century western philosophy. The Treatise addresses many of the most fundamental philosophical issues: causation, existence, freedom and necessity, and morality. The volume also includes Humes own abstract of the Treatise, a substantial introduction, extensive annotations, a glossary, a comprehensive (...) index, and suggestions for further reading. (shrink)
