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.

We extend the monotonic and regular modal logics to the multi-modal cue, and give semantical characterization w.r.t. a semantics of minimal frames. For this we introduce a calculus over neighbourhoods and we obtain simpler conditions than those from the literature.

A major contribution to contemporary social theory. Not only does it provide a compelling critique of some of the main perspectives in 20th century philosophy and social science, but it also presents a systematic synthesis of the many themse which have preoccupied Habermas for thirty years. --Times Literary Supplement.

In this paper we present some concepts and their relations that are necessary for modeling autonomous agents in an environment that is governed by some (social) norms. We divide the norms over three levels: the private level the contract level and the convention level. We show how deontic logic can be used to model the concepts and how the theory of speech acts can be used to model the generation of (some of) the norms. Finally we give some idea about (...) an agent architecture incorporating the social norms based on a BDI framework. (shrink)

In this paper, a model of norms as cognitive objects is applied to establish connections between social conventions and prescriptions. Relevant literature on this issue, especially found in AI and the social sciences, will be shown to suffer from a dychotomic view: a conventionalistic view proposed by rationality and AI scientists; and a prescriptive view proposed by some philosophers of law (Kelsen 1934/1979, Hart 1961, Ross, 1958).In the present work, the attempt is made to fill the gap between these views (...) by putting forward a hypothesis concerning the process from perceived behavioural regularities to normative assumptions. The emergence of norms will be here seen as intrinsically intertwined with the emergence of normative beliefs. Unlike that assumed by the conventionalistic sight, the process of emergence is seen as a non-continuous phenomenon. A given behavioural regularity will be argued to give rise to a normative belief if and as long as that regularity is believed to be prescribed within the community. Two corollaries of this hypothesis will be examined: (1) unlike that implied by the conventionalistic view, the spreading of norms is not only due to a passive behavioural social influence (imitation) but also to an active cognitive one (the spreading of normative wants and beliefs); (2) unlike that assumed by the prescriptive view, a norm is not necessarily explicitly and deliberately issued by some normative authority, but is grounded upon the norm-addressees' beliefs that they are generally prescribed to comply with it.

A method for forcing norms onto individual agents in a multi-agent system is presented. The agents under study are supersoft agents: autonomous artificial agents programmed to represent and evaluate vague and imprecise information. Agents are further assumed to act in accordance with advice obtained from a normative decision module, with which they can communicate. Norms act as global constraints on the evaluations performed in the decision module and hence no action that violates a norm will be suggested to any agent. (...) Further constraints on action may then be added locally. The method strives to characterise real-time decision making in agents, in the presence of risk and uncertainty. (shrink)

In this paper we address the problem of defining social roles in multi-agent systems. Social roles provide the basic structure of social institutions and organizations. We start from the properties attributed to roles both in the multi-agent systems and the Object Oriented community, and we use them in an ontological analysis of the notion of social role. We identify three main properties of social roles. First, they are definitionally dependent on the institution they belong to, i.e. the definition of a (...) role is given inside the definition of the institution. Second, they attribute powers to the agents playing them, like creating commitments for the institutions and the other roles. Third, they allow roles to play roles, in the same way as agents do. Using Input/Output logics, we propose a formalization of roles in multi-agent systems satisfying the three properties we identified. (shrink)

In The Grammar of Society, first published in 2006, Cristina Bicchieri examines social norms, such as fairness, cooperation, and reciprocity, in an effort to understand their nature and dynamics, the expectations that they generate, and how they evolve and change. Drawing on several intellectual traditions and methods, including those of social psychology, experimental economics and evolutionary game theory, Bicchieri provides an integrated account of how social norms emerge, why and when we follow them, and the situations where we are most (...) likely to focus on relevant norms. Examining the existence and survival of inefficient norms, she demonstrates how norms evolve in ways that depend upon the psychological dispositions of the individual and how such dispositions may impair social efficiency. By contrast, she also shows how certain psychological propensities may naturally lead individuals to evolve fairness norms that closely resemble those we follow in most modern societies. (shrink)

Combining principles of individual rational choice with a sociological conception of collective action, James Coleman recasts social theory in a bold new way. The result is a landmark in sociological theory, capable of describing both stability and change in social systems. This book provides for the first time a sound theoretical foundation for linking the behavior of individuals to organizational behavior and then to society as a whole. The power of the theory is especially apparent when Coleman analyzes corporate actors, (...) such as large corporations and trade unions. He examines the creation of these institutions, collective decision making, and the processes through which authority is revoked in revolts and revolutions. Coleman discusses the problems of holding institutions responsible for their actions as well as their incompatibility with the family. He also provides a simple mathematical analysis corresponding to and carrying further the verbal formulations of the theory. Finally, he generates research techniques that will permit quantitative testing of the theory. From a simple, unified conceptual structure Coleman derives, through elegant chains of reasoning, an encompassing theory of society. It promises to be the most important contribution to social theory since the publication of Talcott Parsons' Structure of Social Action in 1936. (shrink)

This book develops a systematic philosophical theory of social action and group phenomena, in the process presenting detailed analyses of such central social notions as 'we-attitude' (especially 'we-intention' and mutual belief, social norm, joint action, and - most important - group goal, group belief, and group action). Though this is a philosophical work, it presents a unified conceptual framework that may be useful to social scientists, especially social psychologists, as well as philosophers. The book puts forward and defends a number (...) of systematic philosophical theses, resulting in not only a theory of social action but, more broadly, a philosophical theory of society, or at least those aspects of society with which social psychology is supposed to deal (individuals in groups, groups, joint action, and the like).

Written in an outstandingly clear and lively style, this 1969 book provokes its readers to rethink issues they may have regarded as long since settled.
