The central topic of this paper is to study joint intention to perform a joint action or to bring about a certain state. Here are some examples of such joint action: You and I share the plan to carry a heavy table jointly upstairs and realize this plan, we sing a duet together, we clean up our backyard together, and I cash a check by acting jointly with you, a bank teller, and finally we together elect a new president for (...) our country. In these cases the participants can be said to have a joint intention jointly or as a group to carry the table upstairs: the content of the intention involves our performing something together and the pronoun “we” refers to us, viz. you and me and the possible other participants considered together. When we jointly intend to carry the table, each of us can be said to.. (shrink)

This paper gives an up-to-date account of we-intentions and responds to some critics of the author’s earlier work on the topic in question. While the main lines of the new account are basically the same as before, the present account considerably adds to the earlier work. For one thing, it shows how we-intentions and joint intentions can arise in terms of the so-called Bulletin Board View of joint intention acquisition, which relies heavily on some underlying mutually accepted conceptual and situational (...) presuppositions but does not require agreement making or joint intention to form a joint intention. The model yields categorical, unconditional intentions to participate in the content of the we-intention and joint intention (viz. shared we-intention upon analysis). The content of a we-intention can be, but need not be a joint action. Thus a participant alone cannot settle and control the content of the intention. Instead the participants jointly settle the content and control the satisfaction of the intention. These and some other features distinguish we-intentions from “action intentions”, viz. intentions that an agent can alone settle and satisfy. The paper discusses weintentions (and other “aim-intentions”) from this perspective and it also defends the author’s earlier account against a charge of vicious circularity that has been directed against it.

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)

University of Cologne, Germany Joint action and group agency have emerged as focuses of attention in recent social theory and philosophy but they have rarely been connected with one another. The argument of this article is that whereas joint action involves people acting together to achieve any sort of result, group agency requires them to act together for the achievement of one result in particular: the construction of a centre of attitude and agency that satisfies the usual constraints of consistency (...) and rationality in adequate measure. The main discovery in the recent theory of group agency is that this result is not easily achieved; no regular voting procedure will ensure, for example, that a group of individually consistent agents will display consistency in group judgments. Key Words: groups • group agents • collective agents • joint action • joint intention. (shrink)

In this paper my concern is with the collective moral responsibility of criminal investigators for the outcomes of their investigations, bearing in mind that it is important to distinguish collective moral responsibility from, and relate it to, individual moral responsibility. In what sense, if any, are police detectives individually and collectively morally responsible for their success (or, for that matter, their failure) in gathering sufficient evidence to identify, arrest, and charge an offender who has committed a serious crime? Alternatively, in (...) what sense are they morally responsible in cases where they identify, arrest, and charge an innocent person? And in what sense, if any, are police detectives individually and collectively morally responsible for the ultimate outcome of the trial, the finding by the courts of someone they have investigated and charged with a serious crime to be guilty or innocent?

In this paper, I explore the relationship between joint epistemic action and collective moral responsibility. Here, we need to distinguish between the genus, joint action, and an important species of joint action which I introduced in some earlier work, namely, joint epistemic action. In the case of the latter, but not necessarily the former, participating agents have epistemic goals, e.g. the acquisition of knowledge. The notion of joint action per se is a familiar one in the philosophical literature, albeit I (...) have provided, and defended, a particular analysis of it. However, the notion of joint epistemic action is a novel one. Nevertheless, I argue that it can be given the same kind of analysis as joint action which is not epistemic in character. The other key notion in play in this paper is that of collective moral responsibility. Over the last decade or two this notion has been receiving a good deal of attention in the philosophical literature. Two influential kinds of theory are non-individualist cor.. (shrink)

In this paper I provide a theory of the speech act of assertion according to which assertion is a species of joint action. In doing so I rely on a theory of joint action developed in more detail elsewhere. Here we need to distinguish between the genus, joint action, and an important species of joint action, namely, what I call joint epistemic action. In the case of the latter, but not necessarily the former, participating agents have epistemic goals, e.g., the (...) acquisition of knowledge. It is joint epistemic action that assertion is a species of. (shrink)

Margaret Gilbert has long defended the view that, roughly speaking, agents share the intention to perform an action if and only if they jointly commit to performing that action. This view has proven both influential and controversial. While some authors have raised concerns over the joint commitment view of shared intention, including at times offering purported counterexamples to certain aspects of the view, straightforward counterexamples to the view as a whole have yet to appear in the literature. Here we provide (...) such counterexamples to show that joint commitment is neither necessary nor sufficient for shared intention. (shrink)

The conventional view of Just War thinking holds that militaries operate under “special” moral rules in war. Conventional Just War thinking establishes a principled approach to such moral exceptionalism in order to prevent arbitrary or capricious uses of military force. It relies on the notion that soldiers are instruments of the state, which is a view that has been critiqued by the Revisionist movement. The Revisionist critique rightly puts greater emphasis on the moral agency of individual soldiers: they are not (...) mere instruments of the state. Although Revisionism has something particularly important to contribute when applied to cases that are short-of-war, where an individual agent’s moral culpability plays a greater role, soldiers fighting wars are not wholly autonomous moral agents. An Institutionalist approach that responds to Revisionist criticisms is a plausible alternative to the conventional Just War account for grounding the moral exceptionalism of war. For the Institutionalist, soldiers are moral agents with state-imposed obligations whose fundamental responsibility is the performance of the proper moral ends of the military institution they serve. If this is true, then soldiers have a moral obligation to be attentive to the moral corruption of the military institution of which they are a part. (shrink)

We all pursue epistemic goals as individuals. But we also pursue collective epistemic goals. In the case of many groups to which we belong, we want each member of the group - and sometimes even the group itself - to have as many true beliefs as possible and as few false beliefs as possible. In this paper, I respond to the main objections to the very idea of such collective epistemic goals. Furthermore, I describe the various ways that our collective (...) epistemic goals can come into conflict with each other. And I argue that we must appeal to pragmatic considerations in order to resolve such conflicts. (shrink)

Neste artigo iremos sistematizar os conceitos-chave da chamada epistemologia coletiva, apontando as diferentes teorias que explicam nossa prática de atribuição de estados cognitivos a grupos. Na introdução levantaremos o problema central que motiva a área, a saber: a atribuição de estados cognitivos a grupos tem como referente o grupo enquanto grupo ou os indivíduos que o compõe? Na primeira seção apresentaremos os melhores argumentos em favor do individualismo, aqueles que defendem que as atribuições se reduzem aos indivíduos. Na segunda, terceira (...) e quarta seções apresentaremos modelos coletivistas, que defendem uma certa autonomia do grupo frente aos indivíduos, o conjunto de membros que o compõe. Na quinta e sexta seções apresentaremos como modelos coletivistas explicam a atribuição de justificação e conhecimento a grupos. Nós concluímos notando que os ataques coletivistas ao individualismo são bastante efetivos, fazendo com que essa abordagem seja difícil de sustentar, e apontando outros elementos que são necessários para a construção de um modelo coletivista completo.

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 essay, I will sketch my view of the connections between some methodological assumptions in social philosophy, namely those of individualism, holism, and collectivism. My interest in doing so is to outline a rough conceptual landscape, into which an approach of collective actions and intentions can be placed.
