Shared agency is of central importance in our lives in many ways. We enjoy engaging in certain joint activities with others. We also engage in joint activities to achieve complex goals. Current approaches propose that we understand shared agency in terms of the more basic phenomenon of shared intention. However, they have presented two antagonistic views about the nature of this phenomenon. Some have argued that shared intention should be understood as being primarily a structure of attitudes of individual participants (...) and their interrelations (Bratman, Searle, Tuomela and Miller). Others have claimed that shared intention should be regarded as being primarily a normative transaction which gives rise to interpersonal obligations (Gilbert). In contrast to these approaches, I propose a compromise view. I argue that shared intention involves a complex socio-psychological structure which ensures, in the absence of special circumstances, the existence of relevant moral obligations. My argument involves two main steps. First, I show that shared intention includes important relations of mutual reliance between the participants. Then, I argue that the existence of these relations of mutual reliance in shared intention helps us explain why, failing special circumstances, shared intention generates those obligations. This provides, in my view, a solution to the vexed question of the relation between shared intention and interpersonal obligations. (shrink)

This is a collection of published and unpublished essays by distinguished philosopher Michael E. Bratman of Stanford University. They revolve around his influential theory, know as the "planning theory of intention and agency." Bratman's primary concern is with what he calls "strong" forms of human agency--including forms of human agency that are the target of our talk about self-determination, self-government, and autonomy. These essays are unified and cohesive in theme, and will be of interest to philosophers in ethics and metaphysics.

What happens to our conception of mind and rational agency when we take seriously future-directed intentions and plans and their roles as inputs into further practical reasoning? The author's initial efforts in responding to this question resulted in a series of papers that he wrote during the early 1980s. In this book, Bratman develops further some of the main themes of these essays and also explores a variety of related ideas and issues. He develops a planning theory of intention. Intentions (...) are treated as elements of partial plans of action. These plans play basic roles in practical reasoning, roles that support the organization of our activities over time and socially. Bratman explores the impact of this approach on a wide range of issues, including the relation between intention and intentional action, and the distinction between intended and expected effects of what one intends.

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)

Human beings act together in characteristic ways. Forms of shared activity matter to us a great deal, both intrinsically – think of friendship and love, singing duets, and the joys of conversation -- and instrumentally – think of how we frequently manage to work together to achieve complex goals. My focus will be on activities of small, adult groups in the absence of asymmetric authority relations within those groups. My approach begins with an underlying model of individual planning agency, and (...) then seeks a conceptual and metaphysical bridge from such individual planning agency to modest forms of sociality.

The everyday concept of a social group is approached by examining the concept of going for a walk together, an example of doing something together, or "shared action". Two analyses requiring shared personal goals are rejected, since they fail to explain how people walking together have obligations and rights to appropriate behavior, and corresponding rights of rebuke. An alternative account is proposed: those who walk together must constitute the "plural subject" of a goal. The nature of plural subjecthood, the thesis (...) that social groups are plural subjects, and the relation of these ideas to Rousseau's and Hobbes 's, are briefly explored. (shrink)

My concern here is to motivate some theses in the philosophy of mind concerning the interpersonal character of intentions. I will do so by investigating aspects of shared agency. The main point will be that when acting together with others one must be able to act directly on the intention of another or others in a way that is relevantly similar to the manner in which an agent acts on his or her own intentions. What exactly this means will become (...) clearer once we understand what it is to act directly on one’s own intentions. But I take it to be a fundamental assumption of the prevailing individualism of the theory of action— one at the core of its conception of the separateness of individuals— that one person cannot act directly on another’s intention. I agree that there is an important way in which we are or can be separate and autonomous thinkers and agents. But the way the individualist tries to capture this separateness is misguided. (shrink)

The subject of personal identity is one of the most central and most contested and exciting in philosophy. Ever since Locke, psychological and bodily criteria have vied with one another in conflicting accounts of personal identity. Carol Rovane argues that, as things stand, the debate is unresolvable since both sides hold coherent positions that our common sense, she maintains, is conflicted; so any resolution to the debate is bound to be revisionary. She boldly offers such a revisionary theory of personal (...) identity by first inquiring into the nature of persons. Rovane begins with a premise about the distinctive ethical nature of persons to which all substantive ethical doctrines, ranging from Kantian to egoist, can subscribe. From this starting point, she derives two startling metaphysical possibilities: there could be group persons composed of many human beings and muliple persons within a single human being. Her conclusions supports Locke's distinction between persons and human beings, but on altogether new grounds. These grounds lie in her radically normative analysis of the condition of personal identity, as the condition in which a certain normative commitment arises, namely, the commitment to achieve overall rational unity within a rational point of view. It is by virtue of this normative commitment that individual agents can engage one another specifically as persons, and possess the distinctive ethical status of persons. Carol Rovan is Associate Professor of Philosophy at Yale University. Originally published in 1997. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

A new volume of philosophical essays by Bernard Williams. The book is a successor to Problems of the Self, but whereas that volume dealt mainly with questions of personal identity, Moral Luck centres on questions of moral philosophy and the theory of rational action. That whole area has of course been strikingly reinvigorated over the last deacde, and philosophers have both broadened and deepened their concerns in a way that now makes much earlier moral and political philosophy look sterile and (...) trivial. Moral Luck contains a number of essays that have contributed influentially to this development. Among the recurring themes are the moral and philosophical limitations of utilitarianism, the notion of integrity, relativism, and problems of moral conflict and rational choice. The work presented here is marked by a high degree of imagination and acuity, and also conveys a strong sense of psychological reality. The volume will be a stimulating source of ideas and arguments for all philosophers and a wide range of other readers. (shrink)

We live in a morally flawed world. Our lives are complicated by what other people do, and by the harms that flow from our social, economic and political institutions. Our relations as individuals to these collective harms constitute the domain of complicity. This book examines the relationship between collective responsibility and individual guilt. It presents a rigorous philosophical account of the nature of our relations to the social groups in which we participate, and uses that account in a discussion of (...) contemporary moral theory. Christopher Kutz shows that the two prevailing theories of moral philosophy, Kantianism and consequentialism, both have difficulties resolving problems of complicity. He then argues for a richer theory of accountability in which any real understanding of collective action not only allows but demands individual responsibility. (shrink)

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.

According to a common claim, a necessary condition for a collective action (as opposed to a mere set of intertwined or parallel actions) to take place is that the notion of collective action figures in the content of each participant’s attitudes. Insofar as this claim is part of a conceptual analysis, it gives rise to a circularity challenge that has been explicitly addressed by Michael Bratman and Christopher Kutz.1 I will briefly show how the problem arises within Bratman’s and Kutz’s (...) analyses, and then proceed to criticize some possible responses, including the ones proposed by Bratman and Kutz. My conclusion is that in order to avoid circularity and retain the features that are supposed to make this sort of account attractive, we need a notion of collectivity that does not presuppose intention. I suggest that we should make a distinction between collective and noncollective activity merely in terms of dispositions and causal agency. There are independent reasons to think that we actually possess such a distinct causal conception of collectivity. It is not necessary for the participants in a jointly intentional collective action to possess a stronger notion of their intended collective activity than this. In particular, they do not need to possess the concept of a jointly intentional collective action. (shrink)

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)

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)

One of the most distinguished living social philosophers, Margaret Gilbert develops and extends her application of plural subject theory of human sociality, first introduced in her earlier works On Social Facts and Living Together. Sociality and Responsibility presents an extended discussion of her proposal that joint commitments inherently involve obligations and rights, proposing, in effect, a new theory of obligations and rights. In addition, it demonstrates the extensive range and fruitfulness of plural subject theory by presenting accounts of social rules, (...) scientific change, political obligation, collective remorse, collective guilt, shared intention and an important class of rights and obligations.

Does one have special obligations to support the political institutions of one’s own country precisely because it is one’s own? In short, does one have political obligations? This book argues for an affirmative answer, construing one’s country as a political society of which one is a member, and a political society as a special type of social group. The obligations in question are not moral requirements derived from general moral principles. They come, rather, from one’s participation in a special kind (...) of commitment: a joint commitment. This theory is referred to as the plural subject theory of political obligation since, by the author’s definition, those who are party to any joint commitment constitute a plural subject of some action in a broad sense of the term. Several alternative theories are compared and contrasted with plural subject theory, with a particular focus on the most famous — actual contract theory — according to which membership in a political society is a matter of participation in an agreement. The book offers plural subject accounts of both social rules and everyday agreements, and includes discussion of political authority and punishment. (shrink)

Christopher Kutz has written an excellent book: part metaphysics, part ethical theory, and part legal philosophy. The aim of the book, as is clear from the title, is to examine and defend the idea of complicity, that is, the responsibility of individuals for their participation in collective harms. While there has not been a lot of philosophical work on this topic, there has been some good work, and Kutz is responsive to most of it. But basically, this book strikes out (...) on its own, building a conception of complicity from an analysis of collective action and individual intention. The cornerstone of the analysis is the idea that individuals should be responsible for what they participate in, regardless of whether the participation makes a causal difference for the outcome.
