In the literature of collective intentions, the ‘we-intentions’ that lie behind cooperative actions are analysed in terms of individual mental states. The core forms of these analyses imply that all Nash equilibrium behaviour is the result of collective intentions, even though not all Nash equilibria are cooperative actions. Unsatisfactorily, the latter cases have to be excluded either by stipulation or by the addition of further, problematic conditions. We contend that the cooperative aspect of collective intentions is not a property of (...) the intentions themselves, but of the mode of reasoning by which they are formed. We analyse collective intentions as the outcome of team reasoning, a mode of practical reasoning used by individuals as members of groups. We describe this mode of reasoning in terms of formal schemata, discuss a range of possible accounts of group agency, and show how existing theories of collective intentions fit into this framework.

This paper proposes a concept of intentional cooperation for mutual benefit. This concept uses a form of team reasoning in which team members aim to achieve common interests, rather than maximising a common utility function, and in which team reasoners can coordinate their behaviour by following pre-existing practices. I argue that a market transaction can express intentions for mutually beneficial cooperation even if, extensionally, participation in the transaction promotes each party’s self-interest.

One of the core issues in contemporary political philosophy is concerned with `political obligation.' Stated in an overly simplified way, the question being asked when one investigates political obligation is, "What, if anything, do citizens owe to their government and how are these obligations generated if they do exist?" The majority of political philosophers investigating this issue agree that a political obligation is a moral requirement to act in certain ways concerning political matters. Despite this agreement about the general nature (...) of what is being searched for, a broad division has arisen between political obligation theorists - there are some who take political obligations to actually exist and there are some who take there to be no general political obligation. While there is debate within the camp defending political obligation about what it is that generates the obligations, the common core of all "defender theories" is the fundamental idea that one has a moral requirement to support and obey the political institutions of one's country. Despite utilitarianism's status as one of the major ethical theories, historically, it has largely been dismissed by theorists concerned with political obligation. Within the contemporary debate it is generally accepted that utilitarianism cannot adequately accommodate a robust theory of political obligation. The overarching objective of this dissertation is to challenge this general dismissal of a utilitarian account and to build upon the two accounts which have been developed in offering a robust utilitarian theory of political obligation which can be considered a competitor to the other contemporary theories. However, as this utilitarian account of political obligation develops, the possibility will also emerge for a non-antagonistic relationship between the utilitarian theory on offer and the contemporary political obligation debate. The moral reasons posited by the traditional theories of political obligation can be included in and accommodated by my utilitarian account. The utilitarian account of political obligation can accept that there are many types of reasons explaining why broad expectations concerning individual and group behavior are created, and each type of reason can be understood as supporting the utilitarian claim that there are moral reasons for following the laws and supporting legitimate political authorities. Taken all together, my arguments will take the form of a three tiered response to the prevailing opinion that any utilitarian attempt to account for political obligations is doomed. The first tier contends that the utilitarian can consistently claim that there are moral reasons to follow the law. This is not a particularly strong claim, but it is one which has been denied by the vast majority of political theorists. The second tier of my argument addresses this apparent issue by contending that even the traditional deontological accounts of political obligation are not offering more than this. Lastly, it is contended that, given the contingent features of humans, the strength of the utilitarian political obligations is comparable to other accounts' analyses of the obligations. (shrink)

In “The Irrelevance of the Diachronic Money-Pump Argument for Acyclicity,” The Journal of Philosophy CX, 8 (August 2013), 460-464, Johan E. Gustafsson contends that if Davidson, McKinsey and Suppes’ diachronic money-pump argument in their "Outlines of a Formal Theory of Value, I," Philosophy of Science 22 (1955), 140-160 is valid, so is the synchronic argument Gustafsson himself offers. He concludes that the latter renders irrelevant diachronic choice considerations in general, and the two best-known diachronic solutions to the money pump problem (...) in particular. I argue here that this reasoning is incorrect, and that Gustafsson’s synchronic argument is faulty on independent grounds. Specifically, it is based on a false analogy between the derivation of a synchronic ordinal ranking from a transitive series of pairwise comparisons, and the putative derivation of such a ranking from an intransitive series. The latter is not possible under the assumption of revealed preference theory, and is highly improbable even if that assumption is rejected. Moreover, Gustafsson’s argument raises issues of fidelity to the historical texts that must be addressed. I conclude that the money pump, and cyclical choice more generally, are necessarily diachronic; and therefore that the two best-known diachronic solutions to the money pump problem remain relevant.

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)

The purpose of this paper is to show how some of the controversial questions concerning utilitarianism can be clarified by the modelling techniques and the other analytical tools of decision theory (and, sometimes, of game theory). It is suggested that the moral rules of utilitarian ethics have a logical status similar to that of the normative rules (theorems) of such formal normative disciplines as decision theory and game theory.The paper argues that social utility should be defined, not in hedonistic or (...) in ideal-utilitarian terms, but rather in terms of individual preferences, in accordance with the author's equiprobability model of moral value judgments.

Act-consequentialism (C) is self-effacing for an agent iff that agent’s not accepting C would produce the best outcome. The question of whether C is self-effacing is important for evaluating C. Some hold that if C is self-effacing that would be a mark against it (Williams 1973: 134); however, the claim that C is self-effacing is also used to defend C against certain objections (Parfit 1984: Ch. 1, Railton 1984). -/- In this paper I will show that one argument suggested by (...) Parfit and Railton fails to establish that C is self-effacing for individuals. However, a slightly different argument may show that C is self-effacing for groups. This raises the intriguing possibility that it might be right for an individual, but not for a group of which they are a member, to accept a moral theory. This possibility, odd though it seems, might be helpful to consequentialists. (shrink)

Cooperation admits of degrees. When factory workers stage a slowdown, they do not cease to cooperate with management in the production of goods altogether, but they are not fully cooperative either. Full cooperation implies that participants in a joint action are committed to rendering appropriate contributions as needed toward their joint end so as to bring it about, consistently with the type of action and the generally agreed upon constraints within which they work, as efficiently as they can, where their (...) contributions are sensitive to information (where available) about how others are contributing in the sense that they adjust as needed their contributions in light of information about how others are contributing to ensure effective pursuit of their joint end, where this includes rendering aid to other participants if needed, insofar as they are able. Full cooperation entails those cooperating are engaged in a joint intentional action. Some prominent studies of joint intentional action focus exclusively on cases of full cooperation (notably that of Michael Bratman (2014)). But not all joint intentional action is fully cooperative. One example is the work slowdown. Another example is provided by competitive games like chess and football, or sports like boxing and wrestling, where participants are clearly not intending to contribute to the pursuit of all of the goals of the others engaged in the activity, even when those goals are internal to the type of activity in question, but instead intend actively to frustrate some of them. In this paper, I provide a taxonomy of forms of non-cooperative behavior within the context of behavior that is still to some degree cooperative, and I argue that the minimal conditions of joint intentional action define minimal cooperative behavior, that is, that minimally joint intentional action is per se minimally cooperative behavior. I define in precise terms what that comes to, and how it is possible in cases in which it seems that one or more participants are in one or more ways acting so as to frustrate the contributions of other participants to their joint action.

Do responsibility voids exist? That is, are there situations in which the group is collectively morally responsible for some outcome although no member can be held individually morally responsible for it? To answer these questions, I draw a distinction between competitive and cooperative decision contexts based on the team-reasoning account of cooperation. Accordingly, I provide a reasoning-based analysis of cooperation, competition, moral responsibility, and, last, potential responsibility voids. I then argue that competitive decision contexts are free of responsibility voids. The (...) conditions for the existence of responsibility voids in cooperative decision contexts depend on the type of uncertainty the group faces, either external or coordination uncertainty.

This article proposes ‘Recursive Consequentialism’: the moral theory which gives agents whatever advice will produce good consequences by being given. It can be thought of as a version of Donald Regan's ‘Cooperative Utilitarianism’ to which two additional elements have been added: allowing people with differing conceptions of ‘good consequences’, e.g., a Utilitarian and a non-Utilitarian, to cooperate with one another, and taking into account the full consequences of accepting, not just complying with, moral guidance. The theory is motivated by a (...) series of game-theoretic examples in which adherence to alternative Consequentialist moral theories produces bad consequences. (shrink)

Let us imagine an ideal ethical agent, i.e., an agent who (i) holds a certain ethical theory, (ii) has all factual knowledge needed for determining which action among those open to her is right and which is wrong, according to her theory, and who (iii) is ideally motivated to really do whatever her ethical theory demands her to do. If we grant that the notions of omniscience and ideal motivation both make sense, we may ask: Could there possibly be an (...) ideal utilitarian, that is, an ideal ethical agent whose ethical theory says that our only moral obligation consists in maximizing utility? I claim that an ideal agent cannot be utilitarian. My reasoning against ideal utilitarianism will parallel Putnam's famous argument against the brains in a vat. Putnam argues that an envatted brain cannot describe its own situation because its words do not refer to brains and vats; I argue that an ideal utilitarian cannot entertain or communicate the beliefs necessary to being a utilitarian.

Despite the strong criticisms to ethical utilitarianism, this theory has not succumbed and remains one of the most notorious. The main criticisms address to the consequentialist conception of right that underlies the theory. However,it has been such a conception of right that, at the same time, saved utilitarianism. The article set out the features and changes that, according to the author, are the causes to explain the subsistence of utilitarianism.

In normative ethics there has been a long-standing debate between consequentialists and deontologists. To settle this dispute moral theorists have often used a selective approach. They have focused on particular aspects of our moral practice and have teased out what consequentialists and deontologists have to say about it. One of the focal points of this debate has been the morality of promising. In this paper I review arguments on both sides and examine whether consequentialists or deontologists offer us a more (...) plausible account of promissory obligation. My conclusion is negative. Given the arguments on the table, I argue, we should conclude that the debate is in a stalemate. It is, therefore, hard to see how the issue of promissory obligation could help us choose between consequentialism and deontology. (shrink)

Successful accounts of analogy in law have two burdens to discharge. First, they must reflect the fact that the conclusion of an argument by analogy is a normative claim about how to decide a certain case. Second, they must not fail to accord relevance to the fact that the source case was authoritatively decided in a certain way. We argue in the first half of this paper that the common view of the structure of analogical arguments in law cannot overcome (...) these hurdles. In the second half we develop an original account that aims to succeed where others failed. (shrink)

This paper reappraises the idea, traceable to Adam Smith, of a fundamental distinction between market transactions and genuinely social relationships. On Smith's account, each party to a market transaction pursues his own interests, subject only to the law of contract. Using the work of Smith's contemporary Antonio Genovesi as our starting point, we reconstruct an alternative understanding of market interactions as instances of a wider class of reciprocal relationships in civil society, characterized by joint intentions for mutual assistance. We consider (...) the implications of our arguments for current debates about whether marketed personal care services can be genuinely caring. (shrink)

A particular problem of traditional Rational Choice Theory is that it cannot explain equilibrium selection in simple coordination games. In this paper we analyze and discuss the solution concept for common coordination problems as incorporated in the theory of Team Reasoning (TR). Special consideration is given to TR’s concept of opportunistic choice and to the resulting restrictions in using private information. We report results from a laboratory experiment in which teams were given a chance to coordinate on a particular pattern (...) of behavior in a sequence of HiLo games. A modification of the stage game offered opportunities to improve on the team goal through changing this accustomed pattern of behavior. Our observations throw considerable doubt on the idea of opportunistic team reasoning as a guide to coordination. Contrary to what TR would predict, individuals tend to stick to accustomed behavioral patterns. Moreover, we find that individual decisions are at least partly determined by private information not accessible to all members of a team. Alternative theories of choice, in particular cognitive hierarchy theory may be more suitable to explain the observed pattern of behavior. (shrink)

Abstract Orthodox decision theory presupposes that agency is invested in individuals. An opposing literature allows team agency to be invested in teams whose members use distinctive modes of team reasoning. This paper offers a new conceptual framework, inspired by David Lewis's analysis of common reasons for belief, within which team reasoning can be represented. It shows how individuals can independently endorse a principle of team reasoning which prescribes acting as a team member conditional on assurance that others have endorsed the (...) same principle. It argues that there can be such assurance even when no individual has an obligation to act on team reasoning. *This paper originated in a lecture that I gave at a Colloquium on Collective Intentions at Erasmus University Rotterdam. I thank participants, and particularly Govert den Hartogh, for comments. The analysis presented in this paper is an offshoot of a larger project, which uses David Lewis's work as the starting point for a reconstruction of the foundations of game theory. That project is joint work with Robin Cubitt. The specific idea of using this approach to analyse team reasoning grew out of a discussion with Michael Bratman. My work was supported by the Leverhulme Trust. (shrink)

In the fourteenth paragraph of the fifth chapter of Utilitarianism, J. S. Mill writes that ‘We do not call anything wrong, unless we mean to imply that a person ought to be punished in some way or other for doing it; if not by law, by the opinion of his fellow-creatures; if not by opinion, by the reproaches of his own conscience.’ I criticize the attempts of three commentators who have recently presented act-utilitarian readings of Mill – Roger Crisp, David (...) Brink, and Piers Norris Turner – to accommodate this passage. (shrink)

We explore the idea that a group or ‘team’ of individuals can be an agent in its own right and that, when this is the case, individual team members use team reasoning, a distinctive mode of reasoning from that of standard decision theory. Our approach is to represent team reasoning explicitly, by means of schemata of practical reasoning in which conclusions about what actions should be taken are inferred from premises about the decision environment and about what agents are seeking (...) to achieve. We use this theoretical framework to compare team reasoning with the individual reasoning of standard decision theory, and to compare various theories of team agency and collective intentionality.

If we overlook no consequences when we assess the act, and no relevant features when we generalize, can it matter whether we ask 'What would happen if everyone did the same?' instead of 'What would happen if this act were performed?'? David Lyons has argued that it cannot. Two examples are here articulated to show that it can. The first turns on the way consequences are identified and assessed and in particular on the treatment accorded 'threshold consequences'. The second example (...) turns on the way in which the 'social context' of the act (what others would be doing) is taken into account in the generalization. Also included is a formal theory of conditionals from which implications are drawn for utilitarianism and with which I attempt to dispel certain doubts concerning cases employed in my arguments.

It is a truism that a market economy cannot function without trust. We must be able to rely on other people to respect our property rights, and on our trading partners to keep their promises. The theory of economics is incomplete unless it can explain why economic agents often trust one another, and why that trust is often repaid. There is a long history of work in economics and philosophy which tries to explain the kinds of reasoning that people use (...) when they engage in practices of trust: this work develops theoriesoftrust. A related tradition in economics, sociology and political science investigates the kinds of social institution that reproduce whatever habits, dispositions or modes of reasoning are involved in acts of trust: this work develops theoriesofsocialcapital. A recurring question in these literatures is whether a society which organizes its economic life through markets is capable of reproducing the trust on which those markets depend. In this paper, we look at these themes in relation to the writings of three eighteenth-century philosopher-economists: David Hume, Adam Smith, and Antonio Genovesi. (shrink)

Coordination problems, problems in which each agent's expected utility depends upon what other agents do, pose a problem for act utilitarianism. When the agents are act utilitarians and know of each other that they are so, they seem unable to achieve optimal outcomes in certain coordination problems. I examine various ways the act utilitarian might attempt to solve this problem, where act utilitarianism is interpreted within the framework of subjective expected utility theory. In particular, a new method for computing expected (...) utility,dynamic deliberation, deserves examination as a possible act utilitarian solution to coordination problems. I argue that even dynamic deliberation fails to give the act utilitarian what he needs in coordination problems, and that the failure of act utilitarianism for such problems suggests the need for an alternative theory of moral choice along rule utilitarian lines.

Utilitarianism has been able to respond to many of the objections raised against it by undertaking a major revision of its theory. Basically, this consisted of recognising that its early normative propositions were only viable for agents very different from flesh-and-blood humans. They then deduced that, given human limitations, it was most useful for everyone if moral agents did not behave as utilitarians and habitually followed certain rules. Important recent advances in neurotechnology suggest that some of these human limitations can (...) be overcome. In this article, after presenting some possible neuro-enhancements, we seek to answer the questions, first, of whether they should be accepted by a utilitarian ethic and, second, if accepted, to what extent they would invalidate the revision that allowed them to escape the objections.

"Guanxi" involves interpersonal obligations, which may conflict with other obligations people have that are based on general or abstract moral considerations. In the West, the latter have been widely accepted as the general source of obligations, which is perhaps tied to social changes associated with the rise of capitalism. Recently, Western ethicists have started to reconsider the extent to which personal relationships may form a distinct basis for obligation. In administration and management, salient bases for decision-Making include deontological, consequentialist and (...) personalist ethics. The first may be reflected in a bureaucratic approach, the second in a price system, and the third in arrangements like "guanxi". Each has positive and negative aspects, but problems arise when they lead to conflicting obligations, as may occur for an office holder who has some obligations based in deontological considerations and others based in personal relationships. This is a type of conflict of interest. Such conflicts have been considered in the West, and remedies proposed. Problems arise especially in cases where it is not clear how to prioritise different obligations, and this has been noted as a difficulty in the Chinese legal system. Questions that need to be answered include not only questions about how to deal with conflicting obligations, but also questions about what institutions to accept as giving rise to obligations. Institutions themselves may be problematic not only because of their consequences for economic productivity, but because they are internally incoherent, and this may be manifested in frequent conflicts faced by office holders.

Mind reading (i.e. the ability to infer the mental state of another agent) is taken to be the main cognitive ability required to share an intention and to collaborate. In this paper, I argue that another cognitive ability is also necessary to collaborate: representing others’ and ones’ own goals from a third-person perspective (other-centred or allocentric representation of goals). I argue that allocentric mind reading enables the cognitive ability of goal adoption, i.e. having the goal that another agent’s achieve p (...) because and as long as another agent has that goal that p. Having clarified the relevance of mutual goal adoption for acting jointly, I argue that when an intention is shared between several agents, each individual has an intention in favour of the joint action and one in favour of a joint mode of reasoning. This mode of reasoning is allocentric reasoning. Finally, I elaborate on the consequences of this view for the scientific study of human collaboration. (shrink)
