This article aims to contribute to a critical ontology of social objects. Recent works on collective intentionality and norm-following neglect the question how free agents can be brought to collectively intend to x , although x is not in their own interest. By arguing for a natural disposition to empathic understanding and drawing on recent research in the neurosciences, this article outlines an ontological framework that extends collective intentionality to questions of oppression and status asymmetries. In a contribution to this (...) journal, Wisnewski (2005) unfortunately mischaracterizes the problem of meaning in social criticism. Implementing status problems in studies of collective intentions and construing social facts as both subjective and objective in character helps explain why agents can have persistent "misunderstandings" of social objects.

In this paper, I review the literature on rational choice theory to scrutinize a number of criticisms that philosophers have voiced against its usefulness in economics. The paper has three goals: first, I argue that the debates about RCT have been characterized by disunity and confusion about the object under scrutiny, which calls into question the effectiveness of those criticisms. Second, I argue that RCT is not a single and unified choice theory—let alone an empirical theory of human behavior—as some (...) critics seem to suppose. Rather, there are several variants of RCT used in economics. Third, I propose that we think of RCT as a set of distinct research strategies to appreciate its diversity. This account implies that the effectiveness of any criticism depends on the variant of RCT we are considering. (shrink)

The paper surveys selected alternative conceptions of rationality in contemporary and (especially) traditional economics and sociology. While the status of rationality as one of the master concepts, subjects and objectives of social science and philosophy has been further promoted in contemporary economics and sociology, questions often arise among economists and sociologists themselves as to its meaning or definition. As an attempt to help address this issue, the paper selects and examines a (limited) number of pertinent definitions and conceptions of rationality (...) from both economic and sociological theory. By virtue of its coverage of economics and sociology, this study is thoroughly interdisciplinary and contributes toward filling in a void in the current literature in which such studies are relatively rare.

Moralising is a venerable last resort strategy. The ancient Melians presented the Athenian generals with a splendid example when in a particularly tight corner. In our Western philosophical tradition moral rhetoric is often couched in the form of reasons for action either external to preference and desire (eg. Kant) or internal to the agent''s calculus of desire (e.g., Hume, Gauthier). A third tradition dismisses such rhetoric as the last recourse of the weak (e.g., Aristotle, Nietzsche) whereas a fourth calls for (...) an examination of the social context (e.g., Socrates, Marx, Wittgenstein, Habermas). This paper reports on an experiment which throws some empirical light on these debates and offers a surprising twist to the interpretation of the Melians'' plea. (shrink)

This commentary focuses on the parts of psychological game theory dealing with preference, as illustrated by team reasoning, and supports the conclusion that these theoretical notions do not contribute above and beyond existing theory in understanding social interaction. In particular, psychology and games are already bridged by a comprehensive, formal, and inherently psychological theory, interdependence theory (Kelley & Thibaut 1978; Kelley et al. 2003), which has been demonstrated to account for a wide variety of social interaction phenomena.

In this paper the problem of the relation between belief and acceptance is discussed in view of recent literature on the topic. Belief and acceptance are characterized in terms of a number of properties, which show both the similarities and the dissimilarities between these notions. In particular it is claimed - contrary to some recently expressed views - that acceptance need not be intentional action and that the differences between belief and acceptance do not boil down to the simple view (...) that acceptance, contrary to belief, is based on the agent's direct exercise of his will. Acceptance which is not based on intentional action is shown in the paper to be especially closely related to belief, especially to linguistic belief. Thus if a person is in a non-intentional-ly acquired and held state of acceptance that something p, he also believes that p. Another general difference is that acceptance is language-dependent while there can be non-linguistic belief. Collective beliefs and acceptances are also briefly discussed in the paper Among other things, it is noted that the notion of wide as contrasted with truth-oriented, narrow acceptance is central in the collective case.

We-thinking theories allow groups to deliberate as agents. They have been introduced into the economic domain for both theoretical and empirical reasons. Among the few scholars who have proposed formal approaches to illustrate how we-thinking arises, Bacharach offers one of the most developed theories from the game theoretic point of view. He presents a number of intuitions, not always mutually consistent and not fully developed. In this article, I propose a way to complete Bacharach’s theory, generalizing the interdependence hypothesis and (...) building on his intuition about vacillation. It is a simple model of vacillation between the I and we-modes of reasoning, as a way in which we-thinking can come to mind in the face of a decision problem. The vacillation model makes we-reasoning more easily usable in game theory. (shrink)

Imagine asking a typical, well informed, contemporary philosopher whether or not she considered biology to be a science. Our informant, being a philosopher, would not necessarily respond with the straightforward “of course” that would be expected from anyone else. She might first reason through a complicated and heavily qualified definition of science, or she might distinguish certain parts of biology that she held to be more clearly scientific than others. If she were partial to a certain sort of critical stance, (...) she might question the political basis for wishing to dignify certain parts of our inquisitive practice with the honorific ‘scientific’ in the first place. But there is at least one thing that she would almost certainly not do. She would not simultaneously embrace a version of the conventional philosophical view of science and deny that biology is a science. This is despite the fact that, as she will acknowledge, biology exploits a range of methodologies and explanatory strategies that have not yet admitted of systematic, consensual philosophical explication.

The thesis of this essay is that social conventions of the kind Lewis modeled are generated and maintained by a form of practical reasoning which is essentially common. This thesis is defended indirectly by arguing for an interpretation of the role of salience in Lewis’s account of conventions. The remarkable ability of people to identify salient options and appreciate their practical significance in contexts of social interaction, it is argued, is best explained in terms of their exercise of what I (...) call “salience reasoning,” a form of common practical reasoning. The more widely accepted understanding of salience competence, the “natural salience” understanding, fails as an interpretation of the notion at work in Lewis and Schelling (on whom Lewis relied) and is inadequate as an explanation of salience competence.

Recently, there has been a debate focusing on the question of whether groups can literally have beliefs. For the purposes of epistemology, however, the key question is whether groups can have knowledge. More specifi cally, the question is whether “group views” can have the key epistemic features of belief, viz., aiming at truth and being epistemically rational. I argue that, while groups may not have beliefs in the full sense of the word, group views can have these key epistemic features (...) of belief. However, I argue that on Margaret Gilbert's infl uential “plural subject” account of group belief, group views are unlikely to be epistemically rational. (shrink)

Mainstream game theory explains cooperation as the outcome of the interaction of agents who permanently pursue their individual goals. Amartya Sen argues instead that cooperation can only be understood by positing a type of rule-following behaviour that can be out of phase with the pursuit of individual goals, due to the existence of a collective identity. However, Sen does not clarify the ontological preconditions for the type of social behaviour he describes. I will argue that Sen's account of collective identity (...) can be best interpreted in the light of John Searle's notion of collective intentionality, while Sen's explanation of rule-following behavior and agency is best understood using the critical realist transformational model of social activity.

Recent developments in game theory have shown that the mathematical models of action so widely admired in the study of economics are in fact only particular instantiations of a more general theoretical framework. In the same way that Aristotelian logic was ‘translated’ into the more general and expressive language of predicate logic, the basic action theoretic underpinnings of modern economics have now been articulated within the more comprehensive language of game theory. But precisely because of its greater generality and expressive (...) power, game theory has again revived the temptation to apply formal models of action to every domain of social life. This movement has been fuelled by some notable successes. Game theory has provided useful insights into the logic of collective action in the theory of public goods, and strategic models of voting have illustrated important aspects of institutional decision-making. But this extension of formal models into every area of social interaction has also encountered significant difficulties, despite the fact that contemporary decision theory has weakened its basic assumptions to the point where it teeters constantly on the brink of vacuity.

This article presents a community-based account of salience as an alternative and a complement to the ‘natural salience’ approach which is endorsed by almost all game theorists who use this concept. While in the naturalistic approach, salience is understood as an objective and natural property of some entities, the community-based account claims that salience is a function of community membership. Building on David Lewis’s theory of common knowledge and on some of its recent refined accounts, I suggest that salience acts (...) as a correlating device in a correlated equilibrium. What is constitutive of salience is common understanding, the fact that agents have common knowledge that they share the same modes of reasoning with respect to a well-identified set of events. I argue that the basis for common understanding is community membership. The relevance of this account stems from the fact that it answers the objection that salience is either unnecessary or unable to account for coordination between rational agents. (shrink)

Collective action is interpreted as a matter of people doing something together, and it is assumed that this involves their having a collective intention to do that thing together. The account of collective intention for which the author has argued elsewhere is presented. In terms that are explained, the parties are jointly committed to intend as a body that such-and-such. Collective action problems in the sense of rational choice theory—problems such as the various forms of coordination problem and the prisoner’s (...) dilemma—are then considered. An explanation is given of how, when such a problem is interpreted in terms of the parties’ inclinations, a suitable collective intention resolves the problem for agents who are rational in a broad sense other than the technical sense of game theory. Key Words: rationality • collective action • collective intention • joint commitment. (shrink)

This paper examines two strands of literature regarding economic models of cooperation. First, payoff transformation theories assume that people may not be exclusively motivated by self-interest, but also care about equality and fairness. Second, team reasoning theorists assume that people might reason from the perspective of the team, rather than an individualistic perspective. Can these two theories be unified? In contrast to the consensus among team reasoning theorists, I argue that team reasoning can be viewed as a particular type of (...) payoff transformation. However, I also demonstrate that many payoff transformations yield actions that team reasoning rules out. (shrink)

Rational choice theory enjoys unprecedented popularity and influence in the behavioral and social sciences, but it generates intractable problems when applied to socially interactive decisions. In individual decisions, instrumental rationality is defined in terms of expected utility maximization. This becomes problematic in interactive decisions, when individuals have only partial control over the outcomes, because expected utility maximization is undefined in the absence of assumptions about how the other participants will behave. Game theory therefore incorporates not only rationality but also common (...) knowledge assumptions, enabling players to anticipate their co-players' strategies. Under these assumptions, disparate anomalies emerge. Instrumental rationality, conventionally interpreted, fails to explain intuitively obvious features of human interaction, yields predictions starkly at variance with experimental findings, and breaks down completely in certain cases. In particular, focal point selection in pure coordination games is inexplicable, though it is easily achieved in practice; the intuitively compelling payoff-dominance principle lacks rational justification; rationality in social dilemmas is self-defeating; a key solution concept for cooperative coalition games is frequently inapplicable; and rational choice in certain sequential games generates contradictions. In experiments, human players behave more cooperatively and receive higher payoffs than strict rationality would permit. Orthodox conceptions of rationality are evidently internally deficient and inadequate for explaining human interaction. Psychological game theory, based on nonstandard assumptions, is required to solve these problems, and some suggestions along these lines have already been put forward. Key Words: backward induction; Centipede game; common knowledge; cooperation; epistemic reasoning; game theory; payoff dominance; pure coordination game; rational choice theory; social dilemma.

Cooperation is the foundation of human social life, but it sometimes requires individuals to choose against their individual self-interest. How then is cooperation sustained? How do we decide when instead to follow our own goals? I develop a model that builds on Bacharach (in: Gold, Sugden (eds) Beyond individual choice: teams and frames in game theory, 2006) ‘circumspect we-reasoning’ to address these questions. The model produces a threshold cost/benefit ratio to describe when we-reasoning players should choose cooperatively. After assumptions regarding (...) player types and beliefs, we predict how the extent of cooperation varies across games. Results from two experiments offer strong support to the models and predictions herein. (shrink)

Game theory is the mathematical study of strategy and conflict. It has wide applications in economics, political science, sociology, and, to some extent, in philosophy. Where rational choice theory or decision theory is concerned with individual agents facing games against nature, game theory deals with games in which all players have preference orderings over the possible outcomes of the game. This paper gives an informal introduction to the theory and a survey of applications in diverse branches of philosophy. No criticism (...) is reviewed. Game theory is shown at work in discussions about epistemological dependence, liberalism and efficiency, Hume’s concept of convention, morality and rationality, and distributive justice and egalitarianism. A guide to the literature provides hints at applications in collective intentionality, epistemology, ethics, history of philosophy, logic, philosophy of language, and political philosophy. (shrink)

:Team reasoning is thought to be descriptively and normatively superior to the classical individualistic theory of rational choice primarily because it can recommend coordination on Hi in the Hi-Lo game and cooperation in Prisoner's Dilemma-type situations. However, left unanswered is whether it is rational for individuals to become team members, leaving a gap between reasons for individuals and reasons for team members. In what follows, I take up Susan Hurley's attempt to show that it is rational for an individual to (...) become a team member. I argue that her account fails to show that becoming a team member is necessary to gain the advantages of coordination in Hi-Lo games or cooperation in Prisoner's Dilemma-type situations, and that individuals will often fare better reasoning as individual agents than as members of a team. I argue further that there is a more general problem for team reasoning, specifically that the conditions needed to make it rational for a team member to employ team reasoning make becoming a team member unnecessary.

Many types of `other-regarding' acts and beliefs cannotbe accounted for satisfactorilyas instances of sophisticated selfishness, altruism,team-reasoning, Kantian duty, kinselection etc. This paper argues in favour ofre-inventing the notion of solidarity as ananalytical category capable of shedding importantnew light on hitherto under-explainedaspects of human motivation. Unlike altruism andnatural sympathy (which turn theinterests of specific others into one's own), orteam-reasoning (which applies exclusivelyto members of some team), or Kantian duty (whichdemands universalisable principlesof action), the essence of solidarity lies in thehypothesis that people (...) are capable ofresponding sympathetically to (or empathising with)a condition afflicting ‘others’,irrespectively of who those others are or whetherone cares for them personally. Andwhen that condition is a social artefact, we argue,solidarity turns radical. (shrink)
