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)

Evolutionary accounts of morality consider behavior in rather simple scenarios. Evolutionary work on fairness focuses on the division of a windfall and, importantly, assumes that the positions of those involved are entirely symmetric. I consider more complicated strategic settings and find that there is a strong tendency for evolution to produce divisions consistent with the so-called Nash bargaining solution. I also uncover the evolutionary importance of comprehensiveness, an often-overlooked feature of division problems.

Though the revised edition of A Theory of Justice, published in 1999, is the definitive statement of Rawls's view, so much of the extensive literature on Rawls's theory refers to the first edition. This reissue makes the first edition once again available for scholars and serious students of Rawls's work.

This is a paperback edition of a major contribution to the field, first published in hard covers in 1977. The book outlines a general theory of rational behaviour consisting of individual decision theory, ethics, and game theory as its main branches. Decision theory deals with a rational pursuit of individual utility; ethics with a rational pursuit of the common interests of society; and game theory with an interaction of two or more rational individuals, each pursuing his own interests in a (...) rational manner.

_ Convention_ was immediately recognized as a major contribution to the subject and its significance has remained undiminished since its first publication in 1969. Lewis analyzes social conventions as regularities in the resolution of recurring coordination problems-situations characterized by interdependent decision processes in which common interests are at stake. Conventions are contrasted with other kinds of regularity, and conventions governing systems of communication are given special attention.

Analyzes the nature of international disagreements and conflict resolution in terms of game theory and non-zero-sum games.

A Treatise of Human Nature was published between 1739 and 1740. Book I, entitled Of the Understanding, contains Hume's epistemology, i.e., his account of the manner in which we acquire knowledge in general, its justification (to the extent that he thought it could be justified), and its limits. Book II, entitled Of the Passions, expounds most of what could be called Hume's philosophy of psychology in general, and his moral psychology (including discussions of the problem of the freedom of the (...) will and the rationality of action) in particular. Book III, entitled Of Morals, is also divided into three parts. Part II of Book III, entitled Of justice and injustice, is the subject of the present volume. In it Hume attempts to give an empiricist theory of justice. He rejects the view, approximated to in varying degrees by Cumberland, Cudworth, Locke, Clarke, Wollaston, and Butler, that justice is something natural and part of the nature of things, and that its edicts are eternal and immutable, and discernible by reason. Hume maintains, on the contrary, as did Hobbes and Mandeville, that justice is a matter of observing rules or conventions which are of human invention, and that, in consequence, our acquiring a knowledge of justice is an empirical affair of ascertaining what these rules or conventions are.
