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.

Courts and commentators are notoriously puzzled about the mens rea standards for complicity. Accomplices intend to aid, but what attitude need they have towards the crimes that they aid? This paper both criticizes extant accounts of the mens rea of complicity and offers a new account. The paper argues that an intention can commit one to an event’s occurrence without committing one to promoting the event, or making it more likely to take place. Under the proposed account of the mens (...) rea of complicity, an accomplice must have an intention that commits him to the crime’s occurrence, but need not commit him to making it more likely that the crime occurs. The paper traces the implications of this view both for several difficult complicity cases, and for ongoing debates among philosophers of action about the necessary and sufficient conditions of joint agency.

Thomas Pogge has argued, famously, that ‘we’ are violating the rights of the global poor insofar as we uphold an unjust international order which provides a legal and economic framework within which individuals and groups can and do deprive such individuals of their lives, liberty and property. I argue here that Pogge’s claim that we are violating a negative duty can only be made good on the basis of a substantive theory of collective action; and that it can only provide (...) substantive ethical guidance when combined with an account of how collective action gives rise to forward-looking responsibility and/or accountability on an individual level. I consider accounts of these two topics given in work by Peter French and Christopher Kutz; and I argue that neither of them give Pogge what he needs. Although there is a sense in which 'we' can be said to be violating the rights of the worst off, the sense in which this is true does not generate any plausible action-guiding claims for individuals.

The Nash counterfactual considers the question: what would happen were I to change my behaviour assuming no one else does. By contrast, the Kantian counterfactual considers the question: what would happen were everyone to deviate from some behaviour. We present a model that endogenizes the decision to engage in this type of Kantian reasoning. Autonomous agents using this moral framework receive psychic payoffs equivalent to the cooperate-cooperate payoff in Prisoner’s Dilemma regardless of the other player’s action. Moreover, if both interacting (...) agents play Prisoner’s Dilemma using this moral framework, their material outcomes are a Pareto improvement over the Nash equilibrium. (shrink)

Intuitively, even very young children can act jointly. For instance, a child and her parent can build a simple tower together. According to developmental psychologists, young children develop theory of mind by, among other things, participating in joint actions like this. Yet many leading philosophical accounts of joint action presuppose that participants have a robust theory of mind. In this article, I examine two philosophical accounts of joint action designed to circumvent this presupposition, and then I proffer my own novel (...) account of what makes (at least some) interactions between very young children and others joint. I argue that children can take up without deliberation intentions with a joint content that have been transmitted to them by others. In doing so, children can come to share intentions with others, and by acting on these shared intentions they can come to act jointly, all without employing a robust theory of mind. (shrink)

The consensus in the philosophical literature on joint action is that, sometimes at least, when agents intentionally jointly φ, this is explicable by their intending that they φ, for a period of time prior to their φ-ing. If this be granted, it poses a dilemma. For agents who so intend either severally or jointly intend that they φ. The first option is ruled out by two stipulations that we may consistently make: (i) that at least one of the agents non-akratically (...) believes that, all things considered, the agents ought not to φ, and (ii) that an agent is akratic, if she intends a thing that she believes, all things considered, ought not to be done. But the second option seems to entail the existence of a mental state with multiple subjects, which, in turn, seems to commit us to the existence of a group mind modified by that state: an incautious posit to say the least. I resolve the dilemma by noting that ‘They jointly intend’ is indeterminate between ‘They intend, jointly’, which does indeed entail that some mental state is an intention with multiple subjects, and ‘Jointly, they intend’, which entails a weaker claim, viz. that some mental state or states is an intention with multiple subjects. I then sketch an account of how a plurality of mental states, distributed among subjects, might, collectively, do service as their intention that they φ. It makes novel use of notions of participation and of doing a thing jointly with others. A corollary is that either intentions are not attitudes towards propositions, or propositions are individuated more finely than is often assumed. (shrink)

I adapt an old example of Frank Jackson's, in order to show that it is not only possible that actions with different individual agents are sub-optimal when each is not, but that they are impermissible when each is not, and blameworthy when each is not.

People walk, build, paint and otherwise act together with a purpose in myriad ways. What is the relation between the actions people perform in acting together with a purpose and the outcome, or outcomes, to which their actions are directed? We argue that fully characterising this relation will require appeal not only to intention, knowledge and other familiar philosophical paraphernalia but also to another kind of representation involved in preparing and executing actions, namely motor representation. If we are right, motor (...) representation plays a central role in the story of acting together. (shrink)

The power to promise is morally fundamental and does not, at its foundation, derive from moral principles that govern our use of conventions. Of course, many features of promising have conventional components—including which words, gestures, or conditions of silence create commitments. What is really at issue between conventionalists and nonconventionalists is whether the basic moral relation of promissory commitment derives from the moral principles that govern our use of social conventions. Other nonconventionalist accounts make problematic concessions to the conventionalist's core (...) instincts, including embracing: the view that binding promises must involve the promisee's belief that performance will occur; the view that through the promise, the promisee and promisor create a shared end; and the tendency to take promises between strangers, rather than intimates, as the prototypes to which a satisfactory account must answer. I argue against these positions and then pursue an account that finds its motivation in their rejection. My main claim is: the power to make promises, and other related forms of commitment, is an integral part of the ability to engage in special relationships in a morally good way. The argument proceeds by examining what would be missing, morally, from intimate relationships if we lacked this power. (shrink)

Do participants in shared activity have mutual obligations to do their bit? This article shows this question has no one-size-fits-all answer and offers a pluralist account of the normativity of shared agency. The first part argues obligations to do one's bit have three degrees of involvement in shared activity. Such obligations might, obviously, bolster co-participants’ resolve to act as planned (degree 1). Less obviously, there also are higher and lower degrees of involvement. Obligations to do one's bit might provide our (...) agency-pooling mechanism. When they do, we act together by virtue of satisfying them (degree 2). Conversely, some shared activities involve no obligation (degree 0). In the second part, I argue shared agency theory is best served by a non-moralistic conception of obligation, one on which co-participants’ obligations need be neither strict-performance obligations, nor directed ones. Overall, my arguments suggest that we can choose how to coordinate normatively our shared activities. (shrink)

This article articulates our everyday notion of cooperation. First, I topple an orthodoxy of shared agency theory by arguing that shared intentions to J are neither necessary nor sufficient for J to be cooperative. I refute the necessity claim by providing examples of shared intention-free cooperation (in institutional contexts and beyond). I refute the sufficiency claim by observing that coercion and exploitation need not preclude shared intentions but do preclude cooperation. These arguments, in turn, lead to my positive proposal. People (...) cooperate, I argue, just in case their activities are coordinated in ways that do not undermine any participant’s agency. (shrink)

This entry addresses the question of group minds, by focusing specifically on empirical arguments for group cognition and group cognitive states. Two kinds of positive argument are presented and critically evaluated: the argument from individually unintended effects and the argument from functional similarity. A general argument against group cognition – which appeals to Occam’s razor – is also discussed. In the end, much turns on the identification of a mark of the cognitive; proposed marks are briefly surveyed in the final (...) section. (shrink)

One important thesis Ásta defends in Categories We Live By is that social properties and categories are somehow dependent on our thoughts, attitudes, or practices—that they are inventions of the mind, projected onto the world. Another important aspect of her view is that the social properties are related to certain base properties; an individual is placed in a category when the relevant base properties are thought to hold of them. I see the relationship between the social and the base as (...) connected to the problem of explaining how the social properties are sufficiently stable so as to be taken seriously, both in theoretical endeavors as well as in practical matters of how we relate to each other. In this light, I identify stability constraints for an adequate account of social categories. I argue that certain distinctive aspects of Ásta's conferralist view of social categories, such as the radical contextualism in her account of gender, undermine the stability of categories and are at odds with taking social categories seriously. I end with the suggestion that a distinctive “sheltered” form of normativity might help us do justice to Ásta's insights while avoiding some of the destabilizing elements of conferralism. (shrink)

Shared activity is often simply willed into existence by individuals. This poses a problem. Philosophical reflection suggests that shared activity involves a distinctive, interlocking structure of intentions. But it is not obvious how one can form the intention necessary for shared activity without settling what fellow participants will do and thereby compromising their agency and autonomy. One response to this problem suggests that an individual can have the requisite intention if she makes the appropriate predictions about fellow participants. I argue (...) that implementing this predictive strategy risks derailing practical reasoning and preventing one from forming the intention. My alternative proposal for reconciling shared activity with autonomy appeals to the idea of acting directly on another's intention. In particular, I appeal to the entitlement one sometimes has to another's practical judgment, and the corresponding authority the other sometimes has to settle what one is to do. (shrink)

Accepting a promise is normatively significant in that it helps to secure promissory obligation. But what is it for B to accept A’s promise to φ? It is in part for B to intend A’s φ-ing. Thinking of acceptance in this way allows us to appeal to the distinctive role of intentions in practical reasoning and action to better understand the agency exercised by the promisee. The proposal also accounts for rational constraints on acceptance, and the so-called directedness of promissory (...) obligation. Finally, the proposal, conjoined with Cognitivism about intentions, addresses recent criticism of Scanlon’s expectation-based view of promissory obligation. (shrink)

What do we owe each other when we act together? According to normativists about collective action, necessarily something and potentially quite a bit. They contend that collective action inherently involves a special normative status amongst participants, which may, for example, involve mutual obligations to receive the concurrence of the others before leaving. We build on recent empirical work whose results lend plausibility to a normativist account by further investigating the specific package of mutual obligations associated with collective action according to (...) our everyday understanding. However, our results cast doubt on a proposed obligation to seek the permission of co-actors before exiting a collective action, and suggest instead that this obligation is a function of explicit promising. We then discuss how our results pave the path for a new normativism, a theory that neither under- nor overshoots the target given by our common conception of the interpersonal obligations present in collective action.*.

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 do lots of things together in a shared manner. From the phenomenological point of view, does joint or shared agency need a conscious sense of shared agency? Yet there are many processes where we seem to just go along with the group without conscious intent. Building on the classic phenomenological accounts of Edmund Husserl, Alfred Schutz, Martin Heidegger (and the synthetic account of Berger & Luckmann), I want to emphasize the thick horizon of the life-world as a fundamental condition (...) for intentional shared agency. Joint agency has divergent forms with their own peculiar intentionality, attentivity, anticipations and expectations, and embeddedness in a pre-predicative tacit knowledge in the overall live-world. Phenomenology recognizes that even ego-centered activities that appear to be fully ‘agential’ can be carried out in an anonymous un-owned manner, in the manner which Heidegger calls ‘das Man’, or ‘the one’. This suggests that tacit belonging to the collective ‘we’ undergirds individual agency. Husserl, Heidegger, and Schutz all have accounts of this ‘anonymous’, pre-predicative kind of group participation. Phenomenology has rich accounts of anonymous, voluntary, shared, social participation that demand a new concept of agency, one neglected in the current literature in philosophy of action. (shrink)

ABSTRACT In what sense is commitment essential to joint action, and do the participants in a joint action themselves perceive commitment as essential? Attempts to answer this question have so far been hampered by clashes of intuition. Perhaps this is because the intuitions in question have mostly been investigated using informal methods only. To explore this possibility, we adopted a more formal approach to testing intuitions about joint action, sampling naïve participants’ intuitions about experimentally controlled scenarios. This approach did reveal (...) patterns in participants’ responses which may hint at potential conceptual links between commitment and joint action. It did not however provide evidence to support the view that commitment is essential to joint action, at least not from the agents’ own perspective. We conclude that intuitions alone, even when drawn systematically from a large sample, may be a poor basis for theorizing about joint action. (shrink)

Agency is the human capacity to freely choose one’s thoughts, motivations and actions without undue internal or external influences; it is distinguished from decisional capacity. Four well-known conditions that can deeply affect agency are depression, demoralization, existential distress, and family dysfunction. The study reviews how they may diminish agency in persons whose circumstances may lead them to consider or request euthanasia or assisted suicide. Since agency has been a relatively neglected dimension of autonomous choice at the end of life, it (...) is argued that to respect the autonomy of individuals, it is essential to establish their agency.

I discuss what I call practical Moore sentences: sentences like ‘You must close your door, but I don’t know whether you will’, which combine an order together with an avowal of agnosticism about whether the order will be obeyed. I show that practical Moore sentences are generally infelicitous. But this infelicity is surprising: it seems like there should be nothing wrong with giving someone an order while acknowledging that you do not know whether it will obeyed. I suggest that this (...) infelicity points to a striking psychological fact, with potentially broad ramifications concerning the structure of norms of speech acts: namely, when giving an order, we must act as if we believe we will be obeyed.

Olle Blomberg challenges three claims in my book From Individual to Plural Agency (Ludwig, Kirk (2016): From Individual to Plural Agency: Collective Action 1. Vols. 2. Oxford: Oxford University Press.). The first is that there are no collective actions in the sense in which there are individual actions. The second is that singular action sentences entail that there is no more than one agent of the event expressed by the action verb in the way required by that verb (the sole (...) agency requirement). The third, is that an individual intention, e.g. to build a boat, is not satisfied if you don’t do it yourself. On the first point, I grant that Blomberg identifies an important distinction between simple and composite actions the book did not take into account, but argue it doesn’t show that there are collective actions in the same sense there are individual actions. On the second point, I argue from examples that the collective reading of plural action sentences doesn’t entail the distributive reading, which requires the sole agency requirement on singular action sentences. This settles the third point, since it entails that if you intend to build a boat, you are successful only if you are the only agent of it in the sense required by the verb. (shrink)

This paper is about first‐person thoughts—thoughts about oneself that are expressible through uses of first‐person pronouns. It is widely held that first‐person thoughts cannot be shared. My aim is to postpone rejection of the more natural view that such thoughts about oneself can be shared. I sketch an account on which such thoughts can be shared and indicate some ways in which deciding the fate of the account will depend upon further work.

Abraham Roth argues that to accept a promise is to intend the performance of the promised action. I argue that this proposal runs into trouble because it makes it hard to explain how promises provide reasons for the performance of the promised action. Then, I ask whether we might fill the gap by saying that a promisor becomes entitled to the reasons for which her promise is accepted. I argue that this fix would implausibly shrink the class of binding promises (...) and suggest that similar difficulties may arise for any theory that casts promises as an exercise of shared agency.

There are two general views that social ontologists currently defend concerning the nature of joint intentional action. According to ‘non-normativists’, for a joint action to be established, we need to align certain psychological states in certain ways. ‘Normativists’ argue that joint action essentially involves normative relations that cannot be reduced to the intentional states of individuals. In two ground-breaking publications, Javier Gomez-Lavin and Matthew Rachar empirically investigate the relation between normativity and joint action in several survey studies. They argue that (...) people's intuitions support neither current normativists nor current non-normativists. They suggest that there is a need for a ‘new normativism of joint action’. I first explore what a new normativism could amount to and conclude that the authors’ findings cannot support a demand for such a view. Finally, I suggest some ideas about how to move the field forward. (shrink)

On the shared-­ends account of close friendship, proper care for a friend as an agent requires seeing yourself as having important reasons to accommodate and promote the friend’s valuable ends for her own sake. However, that friends share ends doesn't inoculate them against disagreements about how to pursue those ends. This paper defends the claim that, in certain circumstances of reasonable disagreement, proper care for a friend as a practical and moral agent sometimes requires allowing her judgment to decide what (...) you are to do, even when you disagree with her judgment (and even when her judgment is in fact mistaken). In these instances, your friendship can make it the case that you may not act on your own practical and even moral judgments because, at those times, you have a duty as her close friend to defer to her judgments. As a result, treating your friend properly as a responsible agent can require that you assist her in committing what may in fact be serious moral wrongs. (shrink)

As diachronic agents, we deliberate and decide in the present to perform future courses of action. Such future‐directed decisions normally enjoy a distinctive species of rational authority over subsequent thought and action. But what is the nature of this authority, and what underwrites its normative force? In this paper, I argue that our answer to this question must begin by situating future‐directed deciding within an intrapersonal model of cross‐temporal influence. The role of future‐directed deciding (and intending), then, is not to (...) generate a novel decision‐based reason for action, but instead to preserve a certain positive normative status over time. I develop an entitlement approach to decisional authority, according to which an agent who rationally decides to ϕ enjoys a practical entitlement, rather than a reason‐based practical justification, to ϕ at the appointed time. This entitlement is underwritten, I argue, by the warrant‐preserving nature of the sequence taking an agent from deliberation to subsequent action. (shrink)

There are modes of presentation of a person in thought corresponding to the first and third person pronouns. This paper proposes that there is also thought involving a second person mode of presentation of another, which might be expressed by an utterance involving ‘you’, but need not be expressed linguistically. It suggests that co-operative activity is the locus for such thought. First person thought is distinctive in how it supplies reasons for the subject to act. In co-operative action there is (...) first person plural intending and judging. So there is a way of thinking of another, when openly co-operating with him or her, which plays the distinctive role of giving reason for contribution to the co-operative activity. In slogan form, ‘you’ is ‘we minus I’. The way children learn to use second and third person pronouns is naturally explained on this view. Contrasting less sophisticated kinds of co-operative activity with more sophisticated forms, and considering some issues about common knowledge and commo.. (shrink)

The debate regarding the nature of joint action has come to a stalemate due to a dependence on intuitional methods. Normativists, such as Margaret Gilbert, argue that action-relative normative relations are inherent in joint action, while non-normativists, such as Michael Bratman, claim that there are minimal cases of joint action without normative relations. In this work, we describe the first experimental examinations of these intuitions, and report the results of six studies that weigh in favor of the normativist paradigm. Philosophical (...) ramifications and further extensions of this work are then discussed. (shrink)

This article explores the question: what is it for two or more people to intend to do something in the future? In a technical phrase, what is it for people to share an intention ? Extending and refining earlier work of the author’s, it argues for three criteria of adequacy for an account of shared intention (the disjunction, concurrence, and obligation criteria) and offers an account that satisfies them. According to this account, in technical terms explained in the paper, people (...) share an intention when and only when they are jointly committed to intend as a body to do such-and-such in the future. This account is compared and contrasted with the common approach that treats shared intention as a matter of personal intentions, with particular reference to the work of Michael Bratman. (shrink)

In this paper, we investigate the role of intention and joint attention in joint actions. Depending on the shared intentions the agents have, we distinguish between joint path-goal actions and joint final-goal actions. We propose an instrumental account of basic joint action analogous to a concept of basic action and argue that intentional joint attention is a basic joint action. Furthermore, we discuss the functional role of intentional joint attention for successful cooperation in complex joint actions.

In this paper, I will discuss the various ways in which intentions can be said to be conditional, with particular attention to the internal conditions on the intentions’ content. I will first consider what it takes to carry out a conditional intention. I will then discuss how the distinctive norms of intention apply to conditional intentions and whether conditional intentions are a weaker sort of commitments than the unconditional ones. This discussion will lead to the idea of what I call (...) the ‘deep structure’ of intentions. Roughly, this is the idea that the conditional nature of our intentions is only partially made explicit in the expressions we use to communicate our intentions and in the explicit form of our thinking about and reasoning with them. Most conditions that qualify our intentions are part of a deep functional structure that can be evinced by observing the actual psychological functioning of intentions and by considering the rational requirements that they engage. I will argue that the deep structure of intentions is characteristically conditional. Genuinely unconditional intentions are only limiting instances of conditional intentions and their contribution to agency can only be understood in light of this fact. I will conclude by showing that the characteristic conditional structure of intentions is intimately related to distinctive features of human agency, especially to its unity over time. (shrink)

This paper concerns the credibility problem for commitments. Commitments play an important role in cooperative human interactions and can dramatically improve the performance of joint actions by stabilizing expectations, reducing the uncertainty of the interaction, providing reasons to cooperate or improving action coordination. However, commitments can only serve these functions if they are credible in the first place. What is it then that insures the credibility of commitments? To answer this question, we need to provide an account of what motivates (...) us to abide by our commitments. We first discuss two conceptions of the nature of the commitments present in joint action and of the norms that govern them. We contend that while normative considerations may have some motivational force, there are reasons to doubt that they, by themselves, could provide a sufficient motivational basis to fully explain why agents abide by their commitments and thus why their commitments are credible. In the next two sections, we discuss two proposals regarding further sources of motivation, reputation management and social emotions. We argue that while reputation management and social emotions certainly play a role in motivating us to act as committed, there are both theoretical and empirical reasons to think that neither captures the most basic motivational force at work in sustaining commitments. We propose instead that the need to belong, i.e., the need to affiliate with others and form long-lasting bonds with them, is what primarily motivates us to interact and engage with those around us and act so as to preserve and reinforce the bonds we have forged with them. We argue that the need to belong is a more basic proximate motivation for conforming to commitments, in the sense both that affiliative behaviors are evidenced much earlier in human development than either reputation management or social emotions and that the need to belong is at least part of an explanation of why we care for our reputation and why we care about others’ assessments of our behavior.

Could interacting mindreaders be in a position to know things which they would be unable to know if they were manifestly passive observers? This paper argues that they could. Mindreading is sometimes reciprocal: the mindreader’s target reciprocates by taking the mindreader as a target for mindreading. The paper explains how such reciprocity can significantly narrow the range of possible interpretations of behaviour where mindreaders are, or appear to be, in a position to interact. A consequence is that revisions and extensions (...) are needed to standard theories of the evidential basis of mindreading. The view also has consequences for understanding how abilities to interact combined with comparatively simple forms of mindreading may explain the emergence, in evolution or development, of sophisticated forms of social cognition.

Cases of modest sociality are cases of small scale shared intentional agency in the absence of asymmetric authority relations. I seek a conceptual framework that adequately supports our theorizing about such modest sociality. I want to understand what in the world constitutes such modest sociality. I seek an understanding of the kinds of normativity that are central to modest sociality. And throughout we need to keep track of the relations—conceptual, metaphysical, normative—between individual agency and modest sociality. In pursuit of these (...) theoretical aims, I propose that a central phenomenon is shared intention. I argue that an adequate understanding of the distinctiveness of the intentions of individuals allows us to provide a construction of attitudes of the participants, and of relevant inter-relations and contexts that constitutes shared intention. I explain how shared intention, so understood, differs from a simple equilibrium within common knowledge. And I briefly contrast my views with aspects of views of John Searle and Margaret Gilbert.

What is required for several agents to intentionally φ together? I argue that each of them must believe or assume that their φ-ing is a single end that each intends to contribute to. Various analogies between intentional singular action and intentional joint action show that this doxastic single end condition captures a feature at the very heart of the phenomenon of intentional joint action. For instance, just as several simple actions are only unified into a complex intentional singular activity if (...) the agent believes or assumes that there is a single end that each action is directed to, so several agents’ actions are only unified into an intentional joint activity if each agent believes or assumes that there is a single end that each intends to contribute to. Influential accounts of intentional joint action, including Christopher Kutz’s and Michael Bratman’s, implicitly include this condition only if participants must intend to contribute to the end under the same conception. While such a requirement successfully rules out some counterexamples, it also makes the accounts unable to appropriately accommodate and explain clear cases of intentional joint action that they ought to be able to accommodate and explain.

In this paper, I distinguish three claims, which I label individual intentional autonomy, individual intentional autarky, and intentional individualism. The autonomy claim is that under normal circumstances, each individual's behavior has to be interpreted as his or her own action. The autarky claim is that the intentional interpretation of an individual's behavior has to bottom out in that individual's own volitions, or pro-attitudes. The individualism claim is weaker, arguing that any interpretation of an individual's behavior has to be given in (...) terms of individual intentional states. I argue that individual intentional autonomy implies neither individual intentional autarky, nor intentional individualism, with which it is usually lumped together. I further argue that this insight is the key to an adequate view of an important class of actions, i.e., plural actions. Key Words: joint action • shared intentions • methodological individualism • intentional interpretation • collective agents • influence • autonomy. (shrink)

This paper develops a new form of metaethical expressivism according to which the normative judgment that X should Φ consists in a decision that X Φ. When the judgment is first-personal—e.g., my judgment that I should Φ—the view is similar to Gibbard’s plan expressivism, though the state I call “decision” differs somewhat from a Gibbard-style plan. The deep difference between the views shows in the account of third-personal judgments. Gibbard construes the judgment that Mary should Φ as a de se (...) plan on the thinker’s part to Φ if she turns out to be Mary (the Subtle View). I construe the judgment as a decision for Mary that Mary Φ (the Simple View). The main argument for Simple Plan Expressivism is that it solves problems for Gibbard’s approach, resonates with a new and interesting moral psychology, and better makes sense of certain independently plausible constraints on normative judgment. In the end I argue that this account of normative judgment has implications for first-order ethics, implying in particular that rational egoism as standardly formulated is incoherent. (shrink)

In this article I propose an original view of the nature of shared intention. In contrast to psychological views (Bratman, Searle, Tuomela) and normative views (Gilbert), I argue that both functional roles played by attitudes of individual participants and interpersonal obligations are factors of central and independent significance for explaining what shared intention is. It is widely agreed that shared intention (I) normally motivates participants to act, and (II) normally creates obligations between them. I argue that the view I propose (...) can explain why it is not a mere accident that both (I) and (II) are true of shared intention, while psychological and normative views cannot. The basic idea is that shared intention involves a structure of attitudes of individuals –including, most importantly, attitudes of reliance – which normally plays the relevant motivating roles and creates the relevant obligations.

The main thesis of this paper is that, whereas an intention simpliciter is a commitment to a plan of action, a conditional intention is a commitment to a contingency plan, a commitment about what to do upon (learning of) a certain contingency relevant to one’s interests obtaining. In unconditional intending, our commitment to acting is not contingent on finding out that some condition obtains. In conditional intending, we intend to undertake an action on some condition, impinging on our interests, which (...) is as yet unsettled for us, but about which we can find out without undue cost.

Andrea Westlund's account of love involves lovers becoming a Plural Subject mirroring Margaret Gilbert's Plural Subject Theory. However, while for Gilbert the creation of a plural will involves individuals jointly committing to pool their wills and the plural will directly normatively constraining those individuals, Westlund, in contrast, sees the creation of a plural will as a continual process thus rejecting the possibility of such direct normative constraint. This rejection appears to be required to explain the flexibility that allows for a (...) central place for reciprocity in loving relationships. However, this paper argues against the existence of such flexibility and presents instead the case that variance in the normative pain of rebelling against the collective will can be accommodated by replacing Gilbert's notion of all-or-nothing pooling of wills with an account that see wills as becoming entangled through levels of identification with the plural subject.

This is a survey article on reductive views of shared intention.

Collective intentionality is one of the most fundamental notions in social ontology. However, it is often thought to refer to a capacity which does not presuppose the existence of any other social facts. This chapter critically examines this view from the perspective of one specific theory of collective intentionality, the theory of Margaret Gilbert. On the basis of Gilbert’s arguments, the chapter claims that collective intentionality is a highly contingent achievement of complex social practices and, thus, not a basic social (...) phenomenon. The argument proceeds in three steps. First, Gilbert’s thesis that certain kinds of collective intentionality presuppose joint normative commitments is introduced. Second, it is argued that, on this view, individual commitments can only constitute the relevant kinds of collective intentional states if there are socially shared “principles of membership” that connect the force of individual commitments to a shared content. Third, it is shown that strong collective intentionality depends on the practical acceptance of shared norms and on the establishment of authority relations through mutual recognition. (shrink)

The phenomenon of shared intention has received much attention in the philosophy of mind and action. Margaret Gilbert (1989, 2000c, 2014b) argues that a shared intention to do A consists in a joint commitment to intend to do A. But we need to know more about the nature of joint commitments to know what exactly this implies. While the persistence of joint commitments has received much attention in the literature, their impersistence has received very little attention. In this paper, we (...) shed light on the impersistence of joint commitments by showing how joint commitments can be dissolved by unexpected events. (shrink)

This contribution provides interdisciplinary analysis of expressions of austerity-policies. It is argued that expressions of austerity-policies are meaningful if and only if intended addressees’ psychological states are adequately attuned and conceptual preconditions for implementation met. Furthermore, it is argued that if addressees are suitably psychologically attuned and preconditions met, utility will, by definition, be maximised and successful economical recovery enjoyed in equal measure among austerity-implementors. The paper is divided into five sections. In the first section the political scene is set (...) in which austerity-policies are expressed and terminology introduced. In the second section expressions of austerity-policies are dissected and analysis of reference conditions of such expressions provided. The third section reviews conceptual analysis of intending and acting together and relates it to jointly implementing austerity-policies. In the fourth section economical rationale behind expressions of austerity-policies is evaluated with reference to what in economical theory is called team-reasoning theory. It is concluded, in section five, that given suitably psychologically attuned implementors of austerity-policies, expressions of austerity-policies are economically rational. But we should be sceptical about their economical motivation: if the people whose actions are meant to implement austerity-policies are distinct from the people whose intentions are meant to be carried out, then it might appear, in the long run, that the former bear a burden for the better of the latter.
