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.

Philosophers and economists write about collective action from distinct but related points of view. This paper aims to bridge these perspectives. Economists have been concerned with rationality in a strategic context. There, problems posed by “coordination games” seem to point to a form of rational action, “team thinking,” which is not individualistic. Philosophers’ analyses of collective intention, however, sometimes reduce collective action to a set of individually instrumental actions. They do not, therefore, capture the first person (...) plural perspective characteristic of team thinking. Other analyses, problematically, depict intentions ranging over others’ actions. I offer an analysis of collective intention which avoids these problems. A collective intention aims only at causing an individual action, but its propositional content stipulates its mirroring in other minds. (shrink)

This entry surveys main accounts of collective intentions.

This paper offers an analysis of the logical form of plural action sentences that shows that collective actions so ascribed are a matter of all members of a group contributing to bringing some event about. It then uses this as the basis for a reductive account of the content of we-intentions according to which what distinguishes we-intentions from I-intentions is that we-intentions are directed about bringing it about that members of a group act in accordance with a shared plan.

The process of cooperative problem solving can be divided into four stages. First, finding potential team members, then forming a team followed by constructing a plan for that team. Finally, the plan is executed by the team. Traditionally, very simple protocols like the Contract Net protocol are used for performing the first two stages of the process. In an open environment however, there can be discussion among the agents in order to form a team that can achieve the collective (...) intention of solving the problem. For these cases fixed protocols like contract net do not suffice. In this paper we present an alternative solution, using structured dialogues, with an emphasis on persuasion, that can be shown to lead to the required team formation. The dialogues are described formally using modal logics and speech acts. (shrink)

This paper argues that a class of popular views of collective intention, which I call “quasi-psychologism”, faces a problem explaining common intuitions about collective action. Views in this class hold that collective intentions are realized in or constituted by individual, mental, participatory intentions. I argue that this metaphysical commitment entails persistence conditions that are in tension with a purported obligation to notify co-actors before leaving a collective action attested to by participants in experimental research about (...) the interpersonal normativity of collective action. I then explore the possibilities open to quasi-psychologists for responding to this research. (shrink)

We ascribe the performance of intentional actions to groups. We claim, for instance, that the orchestra is playing a symphony, that a gang has robbed a bank, and so on. But what is a collective intentional action? Most accounts suggest that, for there to be a collective intentional action, at least two necessary conditions should be met. First, participants must act in accordance with, and because of, the intentions that the group perform a certain action. Second, there must (...) be common knowledge. These accounts, however, face two difficulties. On the one hand, they are uninformatively circular, for they employ in the analysis the very notion of group-action that they are trying to elucidate. On the other hand, they are too demanding, for there are cases of collective intentional action where neither of the conditions is met. The article proposes, by developing further an account put forward by Christopher Kutz, a model of collective intentional actions that overcomes these two problems. It also suggests why such a model is important for our understanding of the law. (shrink)

Voting is a collective activity: it requires more than one person to win a vote. In a corporation, voting allows the winning idea to become an intention of the corporate group once the vote is concluded. In this paper, argue that unlike in corporate boards, in a democratic election, the voting process does not create a group intention. The difference between the two processes is an oft-overlooked moment directly after the corporate vote in which members on the (...) losing side ratify the decision of the group and move on with the group into the future. In state elections, because of the high cost of renouncing membership, there is typically no ratification moment. While different groups do have collective intentions prior to an electoral vote, the vote itself does not manifest the intention of a group agent such as ‘the People.’ This conclusion has implications for minority rights.

Theories of collective intentions must distinguish genuinely collective intentions from coincidentally harmonized ones. Two apparently equally apt ways of doing so are the ‘neo-reductionism’ of Bacharach (2006) and Gold and Sugden (2007a) and the ‘non-reductionism’ of Searle (1990, 1995). Here, we present findings from theoretical linguistics that show that we is not a cognitive primitive, but is composed of notions of I and grouphood. The ramifications of this finding on the structure both of grammatical and lexical systems suggests (...) that an understanding of collective intentionality does not require a primitive we-intention, but the notion of grouphood implicit in team reasoning, coupled with the individual concept I. This, we argue, supports neo-reductionism but poses difficulties for non-reductionism. (shrink)

The following considerations belong to what has recently been discussed as “social ontology”. The paper deals with Searle’s understanding of the difference between social and natural reality. The thesis is that this differentiation falls short because it supports a wrong ontological hierarchy. Social ontology is mistakenly, as I want to show, designed by Searle as a domain-specific ontology subjected to the ontology of nature. I will cast doubt on the persuasive power of this idea by dealing with Searle’s notion of (...) collective intentionality, which lies at the very heart of his doctrine of social and institutional facts: social reality shall originate from collective intentionality. But this notion stands for a wrong objectification of the social, for it is highly questionable whether the social is really exhausted by being the content of our action plans and truth-apt thoughts.

This paper clarifies Searle's account of we-intentions and then argues that it is subject to counterexamples, some of which are derived from examples Searle uses against other accounts. It then offers an alternative reductive account that is not subject to the counterexamples.

The paper discussed and analyzes collective and joint intentions of various strength. Thus there are subjectively shared collective intentions and intersubjectively shared collective intentions as well as collective intentions which are objectively and intersubjectively shared. The distinction between collective and private intentions is considered from several points of view. Especially, it is emphasized that collective intentions in the full sense are in the “we-mode”, whereas private intentions are in the “I-mode”. The paper also surveys (...) recent discussion in the literature concerning the nature of collective and joint intention and defends the author's accounts against criticisms. (shrink)

A substantial literature supports the attribution of intentional states such as beliefs and desires to groups. But within this literature, there is no substantial account of group concepts. Since on many views, one cannot have an intentional state without having concepts, such a gap undermines the cogency of accounts of group intentionality. In this paper I aim to provide an account of group concepts. First I argue that to fix the semantics of the sentences groups use to make their decisions (...) or express their beliefs, we need to appeal to a conventional semantics like that of Lewis. I then argue that the same reasons we have for taking group intentional states to be irreducible to the intentional states of their members apply also to the terms fixed by a conventional semantics. It follows that the meanings of terms in the sentences expressing a group's intentional states are also fixed by facts about the group, not its members. And recognizing this, I argue, amounts to attributing concepts to groups. Finally, I discuss a real-life example of a group concept—the meaning of ‘meter’ as fixed by the International Bureau of Weights and Measurements—and I discuss the upshot of these considerations for the question of social externalism about concepts.

What are the objects of speaker meaning? The traditional answer is: propositions. The traditional answer faces an important challenge: if propositions are the objects of speaker meaning then there must be specific propositions that speakers intend their audiences to recover. Yet, speakers typically exhibit a degree of indifference regarding how they are interpreted, and cannot rationally intend for their audiences to recover specific propositions. Therefore, propositions are not the objects of speaker meaning (Buchanan 2010; MacFarlane 2020a; 2020b; and Abreu Zavaleta (...) 2021). In this paper I do two things. Firstly, I outline a collective analogue of this challenge that undermines the most prominent responses to the original challenge. Secondly, I provide a new solution: typical utterances are backed by a cluster of partial communicative intentions. This response resolves both individual and collective variants of the problem and allows us to retain the traditional propositional view of speaker meaning. (shrink)

The literature on collective action largely ignores the constraints that moral principle places on action-prompting intentions. Here I suggest that neither individualism nor holism can account for the generality of intentional contents demanded by universalizability principles, respect for persons, or proactive altruism. Utilitarian and communitarian ethics are criticized for nominalism with respect to social intentions. The failure of individualism and holism as grounds for moral theory is confirmed by comparing Tuomela's reductivist analysis of we-intentions with Gilbert's analysis of social (...) facts. Tuomela's account founders over intentions to cooperate, and Gilbert's cannot accommodate legitimate authority, vicarious agency, or group structure. (shrink)

What do we mean when we say that some group believes something? Do we simply mean that all the members of the group believe it, or are we acknowledging the existence of some kind of group agent? According to Margaret Gilbert, talk about group mental states refers to the specific kind of agreements she calls joint commitments — that is, to collectively believe something means to be committed with others to believe it. In my article, I will first present Gilbert’s (...) approach in more detail but will ultimately show that this approach is problematic and will refute it. I will briefly consider the most common solution to the problems Gilbert’s account faces, which lies in replacing collective beliefs with acceptances, but I will show that this solution will not do either. The solution I will then present will be based on Daniel Dennett’s intentional strategy, which is a method of interpreting the things around us and predicting their behaviour by treating them as rational agents with relevant intentions. I will try to show that all the problematic cases of collective belief can be explained by applying the intentional strategy to the groups in question. (shrink)

Intention and Identity presents John Finnis's accounts of personal existence; group identity and common good; and the moral significance of personal intention. Joining conceptual analysis with ethical problems surrounding the beginning and end of life, the papers show the power of a neglected aspect of Finnis's natural law theory.

Draft as of 2001 of a book chapter a^ppeared in 2005. This paper gives an account of the belief/ acceptance distrinction applied to the issue of collective beliefs and intentionality in terms of the "doctrinal dilemma" proposed by some legal theorists.

Human interactions are often improvised rather than scripted, which suggests that efficient coordination can emerge even when collective plans are largely underspecified. One possibility is that such forms of coordination primarily rely on mutual influences between interactive partners, and on perception–action couplings such as entrainment or mimicry. Yet some forms of improvised joint actions appear difficult to explain solely by appealing to these emergent mechanisms. Here, we focus on collective free improvisation, a form of highly unplanned creative practice (...) where both agents' subjective reports and the complexity of their interactions suggest that shared intentions may sometimes emerge to support coordination during the course of the improvisation, even in the absence of verbal communication. In four experiments, we show that shared intentions spontaneously emerge during collective musical improvisations, and that they foster coordination on multiple levels, over and beyond the mere influence of shared information. We also show that musicians deploy communicative strategies to manifest and propagate their intentions within the group, and that this predicts better coordination. Overall, our results suggest that improvised and scripted joint actions are more continuous with one another than it first seems, and that they differ merely in the extent to which they rely on emergent or planned coordination mechanisms.

SOCREAL 2010: 2nd International Workshop on Philosophy and Ethics of Social Reality. Sapporo, Japan, 2010-03-27/28. Session 3: Responsibility and Collective Agency.

Shared agency is a distinctive kind of sociality that involves interdependent planning, practical reasoning, and action between participants. Philosophical reflection suggests that agents engage in this form of sociality when a special structure of interrelated psychological attitudes exists between them, a set of attitudes that constitutes a collective intention. I defend a new way to understand collective intention as a combination of individual conditional intentions. Revising an initial statement of the conditional intention account in response (...) to several challenges leads to a specification of the properties these intentions need to have in order to be genuine commitments. I then show how a structure of conditional intentions with these properties settles a collection of agents on engaging in social interactions that display all the features typically associated with shared agency.

In a distributed multi-agent system, an idle agent may be available to assist other agents in the system. An agent architecture called intent recognition is proposed in this article to accomplish this with minimal communication. To assist other agents in the system, an agent performing recognition observes the tasks other agents are performing. Unlike the much-studied field of plan recognition, the overall intent of an agent is recognized instead of a specific plan. The observing agent may use capabilities that it (...) has not observed. In this study, the key research question is: What are intent-recognition systems and how can these be used to have agents autonomously assist each other effectively and efficiently? A conceptual framework is proposed to address this question. An implementation of the conceptual framework is tested and evaluated. A set of metrics, including task time and number of communications, is used to compare the performance of plan recognition and intent recognition. This research shows that under certain conditions, an intent-recognition system is more efficient than a plan recognition system. (shrink)

Reflecting on the months leading up to and following the 2016 United States presidential election, in an essay published in January of 2017 I argued that the left/right dichotomy of the Democrats and the Republicans was no longer carving at a joint of American politics (Stovall, 2017). Instead, it seemed a more salient political division in the U.S. was that between what I called the urban globalists and the non-urban nationalists. This essay situates the apparent conflict between urban globalism and (...) non-urban nationalism in the context of a development in European self-understanding owed to German idealism. I will articulate this self-understanding by relating it to the period of the European Enlightenment, and in the process I will argue that a theory of collective intentions may point the way toward a more thorough understanding of the phenomena that lie behind the growing opposition between nationalist and globalist tendencies in Europe and the United States today.

This collection of essays by one of the most prominent and internationally respected philosophers of action theory is concerned with deepening our understanding of the notion of intention. In Bratman's view, when we settle on a plan for action we are committing ourselves to future conduct in ways that help support important forms of coordination and organization both within the life of the agent and interpersonally. These essays enrich that account of commitment involved in intending, and explore its implications (...) for our understanding of temptation and self-control, shared intention and shared cooperative activity, and moral responsibility. The essays offer extensive discussions of related views by, among others, Donald Davidson, Hector-Neri Castañeda, Christine Korsgaard, Harry Frankfurt, and P. F. Strawson. This collection will be a valuable resource for a wide range of philosophers and their students. (shrink)

This book focuses on the complex phenomenon of group morality and collective responsibility. It provides an analytic understanding of moral culpability of collective entities implicated in some of the most pressing contemporary ethical issues such as institutional injustice, corporate scams, organized crimes, gang wars, group-based violence, genocide, xenophobia, and the like. Delving deeper into the concept of collective responsibility, it asks--Who is responsible when a collective is held responsible? Is collective responsibility merely a façon de (...) parler, a rhetoric of talking about individual moral responsibility, or more than that? The volume develops a non-individualist account by using some of the latest resources from philosophy of action, philosophy of mind, and social ontology. It interprets collective responsibility as the responsibility of a collective without either reducing it to shared and individual responsibility of the group members or making it a case where their moral positions are completely blurred. An important intervention in moral philosophy, this book will be useful for scholars and researchers of moral philosophy, philosophy of action and mind, philosophy of social sciences, and political philosophy. It will also be a theoretical resource for legal theorists, just war theorists, game theorists, business ethicists, and policy makers. (shrink)

One of the currently most discussed themes in the philosophy of action is whether there is some kind of collective intention that explains what groups do independent of what the indi-viduals who make up the group intend and do. One of the main obstacles to solve this prob-lem is that on the one hand collective intentionality is no simple summation, aggregate, or dis-tributive pattern of individual intentionality (the Irreducibility Claim), while on the other hand collective intentionality (...) is in the heads of the participating individuals, so to speak, and so it is owned by each of the separate individuals who make up the group (the Individual Ownership Claim). The claims are contradictory and until now no satisfactory solution how to reconcile them has been found. In this article I argue that the constitution view, like the one developed by Lynne R. Baker, can provide a way to sidestep the contradiction. Just as a statue as such is constituted by the marble it is made of but has characteristics that are different from the mar-ble (a statue has a head and legs, while the marble hasn’t; while the marble is stony and the statue as such isn’t), I argue that a group is constituted by its members and that a group on the one hand and its members on the other hand have different characteristics. This is possible be-cause group and members are on different levels. Then there is no longer a contradiction be-tween the Irreducibility Claim and the Individual Ownership Claim, for the former claim con-cerns the group level and the latter claim concerns the level of the group members. This ex-plains that a group can have intentions that are no simple summation, aggregate, or distributive patterns of the intentions of its members and that group intentions can be different from if not contradictory to what the individual members taken together intend.

We study shared intentions in what we call “loose groups”. These are groups that lack a codified organizational structure, and where the communication channels between group members are either unreliable or not completely open. We start by formulating two desiderata for shared intentions in such groups. We then argue that no existing account meets these two desiderata, because they assume either too strong or too weak an epistemic condition, that is, a condition on what the group members know and believe (...) about what the others intend, know, and believe. We propose an alternative, pooled knowledge, and argue that it allows formulating conditions on shared intentions that meet the two desiderata. (shrink)

This is a review essay of Christopher Kutz's Complicity: Ethics and Law for a Collective Age, and Jonathan Bass's Stay The Hand of Vengeance: The Politics of War Crimes Tribunals. Topics addressed include the nature of collective intentions and actions, the possibility of collective guilt, the moral responsibility of individuals in the context of collective actions.

This paper examines whether Bratman’s succeeds in provides a reductive account of collective intention.

"Dimensions of Shared Agency" investigates the way in which standard philosophical accounts have been dealing with the issue of collective actions. In particular, the book focuses on the 'Big Five' of analytical social ontology and their accounts of shared/collective intentions and actions. Through systematic readings of different positions in the debate, the author proposes original ways of analyzing and classifying current theories of shared agency according to whether they advance a member-level or a group-level account of shared agency. (...) While member-level accounts are theories of shared agency based on individuals' attitudes and actions, group-level accounts give attention to the group of individuals considered as a whole, i.e., as an agent itself. Criticism arises against the idea that the Big Five have proposed stable group-level accounts suitable for explaining the case of shared agency as a group-level phenomenon. The widespread tendency in the debate is to endorse a perspective called holistic individualism, which maintains that high-level explanations are objective even though social facts are ontologically reducible to facts about individuals. Lasagni argues that as long as holistic individualism is held, the GLA is reducible to the MLA because holistic individualism upholds ontological individualism based on a deep individualistic premise, fixing the special status of individual agents as natural persons. The premise makes the claim to treat groups as agents contradictory to the general framework of the theory. This book profiles an alternative interpretation according to which agency should be considered as a functional kind, which is equally instantiated by different systems, such as individual human beings and organized social groups. In this way, the author claims, the reduction of the social can be avoided. "Dimensions of Shared Agency" will be of interest to doctoral students, researchers, and scholars interested in social ontology and the philosophy of the social sciences. It can also be utilised as supplementary reading or an introduction to philosophy students and scholars who are first approaching the philosophy of collective intentionality and shared agency.

The theory of collective agency and intentionality is a flourishing field of research, and our understanding of these phenomena has arguably increased greatly in recent years. Extant theories, however, are still ill-equipped to explain certain aspects of collective intentionality. In this article we draw attention to two such underappreciated aspects: the failure of the intentional states of collectives to supervene on the intentional states of their members, and the role of non-human factors in collective agency and intentionality. (...) We propose a theory of collective intentionality which builds on the ‘interpretationist’ tradition in metasemantics and the philosophy of mind as initiated by David Lewis and recently developed further by Robbie Williams. The collective-level analogue of interpretationism turns out to look different in some ways from the individual-level theory, but is well-suited to accommodating phenomena such as hybrid collective intentionality. Complemented with Kit Fine’s theory of variable embodiment, such a theory also provides a diachronic account of intentional collectives. (shrink)
