This book offers original accounts of a number of central social phenomena, many of which have received little if any prior philosophical attention. These phenomena include social groups, group languages, acting together, collective belief, mutual recognition, and social convention. In the course of developing her analyses Gilbert discusses the work of Emile Durkheim, Georg Simmel, Max Weber, David Lewis, among others.

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

What is it for marks or sounds to have meaning, and what is it for someone to mean something in producing them? Answering these and related questions, Schiffer explores communication, speech acts, convention, and the meaning of linguistic items in this reissue of a seminal work on the foundations of meaning. A new introduction takes account of recent developments and places his theory in a broader context.

A feature of David Lewis's account of conventions in his book "Convention" which has received admiring notices from philosophers is his use of the mathematical theory of games. In this paper I point out a number of serious flaws in Lewis's use of game theory. Lewis's basic claim is that conventions cover 'coordination problems'. I show that game-Theoretical analysis tends to establish that coordination problems in Lewis's sense need not underlie conventions.

What is it for a group to believe something? A summative account assumes that for a group to believe that p most members of the group must believe that p. Accounts of this type are commonly proposed in interpretation of everyday ascriptions of beliefs to groups. I argue that a nonsummative account corresponds better to our unexamined understanding of such ascriptions. In particular I propose what I refer to as the joint acceptance model of group belief. I argue that group (...) beliefs according to the joint acceptance model are important phenomena whose aetiology and development require investigation. There is an analogous phenomenon of social or group preference, which social choice theory tends to ignore. (shrink)

In the days when the Great Central and the Midland ran competitive services from Leicester to London, I agreed to meet your train when you came up from Leicester. “It arrives at 12.5”, you said in your letter. But you neglected to mention which station, and only on the morning of your journey did each of us realize that this matter had been left open. You intended to travel from Leicester Central, it being more convenient for you than London Road, (...) and you supposed that I would be able to infer your intention by consulting Bradshaw, and noting a 12.5 arrival from Leicester at Marylebone.

A number of authors, Including Thomas Schelling and David Lewis, have envisaged a model of the generation of action in coordination problems in which salience plays a crucial role. Empirical studies suggest that human subjects are likely to try for the salient combination of actions, a tendency leading to fortunate results. Does rationality dictate that one aim at the salient combination? Some have thought so, Thus proclaiming that salience is all that is needed to resolve coordination problems for agents who (...) are rational in the sense of game theory. I argue against this position; rational agents will not necessarily aim for the salient. It remains to explain how the salient comes to be chosen by human beings. Various possibilities are noted. One involves a mechanism invoked by Hume and Wittgenstein in other contexts: we may project an unreasoned compulsion onto reason, falsely believing that rationality dictates our choice of the salient.

The question whether and in what way languages and language use involve convention is addressed, With special reference to David Lewis's account of convention in general. Data are presented which show that Lewis has not captured the sense of 'convention' involved when we speak of adopting a linguistic convention. He has, In effect, attempted an account of social conventions. An alternative account of social convention and an account of linguistic convention are sketched.

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.

This book uses game theory to analyse the creation, evolution and function of economic and social institutions. The author illustrates his analysis by describing the organic or unplanned evolution of institutions such as the conventions of war, the use of money, property rights and oligopolistic pricing conventions. Professor Schotter begins by linking his work with the ideas of the philosophers Rawls, Nozick and Lewis. Institutions are regarded as regularities in the behaviour of social agents, which the agents themselves tacitly create (...) to solve a wide variety of recurrent problems. The repetitive nature of the problems permits them to be described as a recurrent game or 'supergame.' The agents use these regularities as informational devices to supplement the information contained in competitive prices. The final chapter explores the applicability of this theory, first by relating it to previous work on the theory of teams, hierarchies, and non-maximizing decision theory, and then by using it to provide a new approach to a variety of questions both within and outside economics.

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.
