This entry surveys main accounts of collective intentions.

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)

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.

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. (shrink)

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)

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 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)

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. (shrink)

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.

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.

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 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)

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.

This third book in the GRIT collection of stories will inspire readers to deliberately navigate life's challenges. Each chapter captures a dynamic woman's authentic story of how they have lived with intention--either personally or professionally. Intention helps us define our personal purpose, teaches us to trust our internal compass, and helps us to master self-discipline. Intention brings clarity to chaos and helps us overcome obstacles as they arise on our journey.--Publisher.

Michael Tomasello’s account of moral evolution includes both a synthesis of extensive experimental work done on humans and chimpanzees on their potential for perspective-taking and helpful, altruistic generosity and a major emphasis on “collective intentionality” as an important component of morality in humans. Both will be very useful to the evolutionary study of this subject. However, his disavowal of collective intentions on the parts of chimpanzees would appear to be empirically incorrect, owing to reliance on experimental captive (...) research focused only on dyadic interactions. Here, evidence to the contrary is provided from studies of wild chimpanzees as they naturally cooperate in sizable groups. Collective intentions are inferable when they go on patrol, when they mob predators, when they go hunting, and when large coalitions gang-attack disliked members of the same community. This last behavior has particularly significant pre-adaptive implications for the evolution of moralistic social control, and it suggests that moral evolution has deep roots, going back to the Last Common Ancestor of humans, bonobos, and chimpanzees.

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.

"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.

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.

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)

_ Source: _Page Count 13 The article starts with the theses that it is the very concept of action that is at stake in many debates between philosophers and historians. Whereas in philosophy actions are conceptualized by reference to their beginning, namely their motives or intentions, in historiography the consequences of actions are much more in the focus of interest. Especially the debate about the dualism of structure and agency is characterized by different concepts of action. In the article (...) it is argued that this dualism can be overcome by stressing the intentionality of collective actions. First, a concept of action is developed against the background of a theory of intentionality. Second, intentional collective action is distinguished from individual and social actions and an analysis of a collective we-intention is proposed. Third, it is argued that the development of social structures has to be understood by reference to intentional collective actions. (shrink)

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.

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

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 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.

Many of the things we do, we do together with other people. Think of carpooling and playing tennis. In the past two or three decades it has become increasingly popular to analyze such collective actions in terms of collective intentions. This volume brings together ten new philosophical essays that address issues such as how individuals succeed in maintaining coordination throughout the performance of a collective action, whether groups can actually believe propositions or whether they merely accept (...) them, and what kind of evidence, if any, disciplines such as cognitive science and semantics provide in support of irreducibly collective states.The theories of the Big Four of collective intentionality -- Michael Bratman, Raimo Tuomela, John Searle, and Margaret Gilbert -- and the Big Five of Social Ontology -- which in addition to the Big Four includes Philip Pettit -- play a central role in almost all of these essays. Drawing on insights from a wide range of disciplines including dynamical systems theory, economics, and psychology, the contributors develop existing theories, criticize them, or provide alternatives to them.Several essays challenge the idea that there is a straightforward dichotomy between individual and collective level rationality, and explore the interplay between these levels in order to shed new light on the alleged discontinuities between them. These contributions make abundantly clear that it is no longer an option simply to juxtapose analyses of individual and collective level phenomena and maintain that there is a discrepancy. Some go as far as arguing that on closer inspection the alleged discontinuities dissolve. (shrink)

Collective Action, Philosophy and Law brings together two important strands of philosophical analysis. It combines general philosophical inquiry into collective agency with analyses of specific questions about plural entities and activities in the legal domain. These are issues of growing interest in areas of philosophy like action theory and social ontology, as well as in philosophy of law. The book contains thirteen original chapters written by an international team of leading philosophers and legal theorists, and is divided into (...) four clear parts: The nature of law and of legislative intention Practical reasoning and duties Causality, blameworthiness, and responsibility Citizens, states, and institutions. These sections cut across, and build on, different accounts to advance the debate on classical and new issues in collective agency. Each part also features legal-philosophical analyses that draw on general accounts of collective agency to cast new light on the law, descriptive as well as normatively. Collective Action, Philosophy and Law is the first major interdisciplinary and multi-authored work bridging legal and philosophical approaches to collective agency. As such, it is essential reading for students and researchers of philosophy of law, ethics, political philosophy, jurisprudence, and legal theory. (shrink)

This article develops an ecological framework for understanding collective action. This is contrasted with approaches familiar from the collective intentionality debate, which treat individuals (with collective intentions) as fundamental units of collective action. Instead, we turn to social ecological psychology and dynamical systems theory and argue that they provide a promising framework for understanding collectives as the central unit in collective action. However, we submit that these approaches do not yet appreciate enough the relevance (...) of social identities for collective action. To analyze this aspect, we build on key insights from social identity theory and synthesize it with embodied and ecological accounts of perception and action. This results in the proposal of two new types of affordances. For an individual who enacts her "embodied social identity" of being a member of a particular collective, there can be what we call embodied social identity affordances. Moreover, when several individuals dynamically interact with each other against the background of their embodied social identities, this might lead to the emergence of a collective, which we understand as a dynamically constituted and ecologically situated perception-action system consisting of several individuals enacting relevant embodied social identity affordances. Building on previous work in social ecological psychology, we suggest that there can be genuine collective affordances, that is, affordances whose subject is not an individual, but a collective.

This volume of _Midwest Studies_ focuses on the currently hot topic in ethics and action theory of shared intentions and relates it to issues in collective responsibility. Each of the essays in the volume is by an internationally known scholar who has published seminal pieces on various aspects of the concepts of shared intention and collective responsibility. Features all new essays that expand the discussion and invite those interested in the topic to examine a variety of ways (...) for understanding the basic idea and the application of the notion of shared intention to a range of contemporary issues in the ethics of responsibility.

In this paper, we offer an analysis of ‘group intentions.’ On our proposal, group intentions should be understood as a state of equilibrium among the beliefs of the members of a group. Although the discussion in this paper is non-technical, the equilibrium concept is drawn from the formal theory of interactive epistemology due to Robert Aumann. The goal of this paper is to provide an analysis of group intentions that is informed by important work in economics and (...) formal epistemology. (shrink)

This book includes ten original essays that critically examine central themes of John Searle’s ontology of society, as well as a new essay by Searle that summarizes and further develops his work in that area. The critical essays are grouped into three parts. Part I (Aspects of Collective Intentionality) examines the account of collective intention and action underlying Searle’s analysis of social and institutional facts, with special emphasis on how that account relates to the dispute between individualism and (...) anti-individualism in the analysis of social behaviour, and to the opposition between internalism and externalism in the analysis of intentionality. Part II (From Intentions to Institutions: Development and Evolution) scrutinizes the ontogenetic and phylogenetic credentials of Searle’s view that, unlike other kinds of social facts, institutional facts are uniquely human, and develops original suggestions concerning their place in human evolution and development. Part III (Aspects of Institutional Reality) focuses on Searle’s claim that institutional facts owe their existence to the collective acceptance of constitutive rules whose effect is the creation of deontic powers, and examines central issues relevant to its assessment (among others, the status of the distinction between regulative and constitutive rules, the significance of the distinction between brute and deontic powers, the issue of the logical derivability of normative from descriptive propositions, and the import of the difference between moral and non-moral normative principles). Written by an international team of philosophers and social scientists, the essays aim to contribute to a deeper understanding of Searle’s work on the ontology of society, and to suggest new approaches to fundamental questions in that research area.
