Kirk Ludwig develops a novel reductive account of plural discourse about collective action and shared intention. Part I develops the event analysis of action sentences, provides an account of the content of individual intentions, and on that basis an analysis of individual intentional action. Part II shows how to extend the account to collective action, intentional and unintentional, and shared intention, expressed in sentences with plural subjects. On the account developed, collective action is a matter of there being multiple agents of an event and it requires no group agents per se. Shared intention is a matter of agents in a group each intending that they bring about some end in accordance with a shared plan. Thus their participatory intentions (their we-intentions) differ from individual intentions not in their mode but in their content. Joint intentional action then is a matter of a group of individuals successfully executing a shared intention. The account does not reduce shared intention to aggregates of individual intentions. However, it argues that the content of we-intentions can be analyzed wholly in terms of concepts already at play in our understanding of individual intentional action. The account thus vindicates methodological individualism for plural agency. The account is contrasted with other major positions on shared intention and joint action, and defended against objections. This forms the foundation for a reductive account of the agency of mobs and institutions, expressed in grammatically singular action sentences about groups and their intentions, in a second volume.

Kirk Ludwig develops a novel reductive account of plural discourse about collective action and shared intention. He argues that collective action is a matter of there being multiple agents of an event and requires no group agents, while shared intentions are distributions of intentions across members of the group.

Kirk Ludwig presents a philosophical account of institutional action, such as action by corporations and nation states. He argues that it can be fully understood in terms of the agency of individuals, and concepts derived from our understanding of individual action. He thus argues for a strong form of methodological individualism.

Collective Intentionality is a relatively new label for a basic social fact: the sharing of attitudes such as intentions, beliefs and emotions. This volume contributes to current research on collective intentionality by pursuing three aims. First, some of the main conceptual problems in the received literature are introduced, and a number of new insights into basic questions in the philosophy of collective intentionality are developed (part 1). Second, examples are given for the use of the analysis of collective intentionality in the theory and philosophy of the social sciences (part 2). Third, it is shown that this line of research opens up new perspectives on classical topics in the history of social philosophy and social science, and that, conversely, an inquiry into the history of ideas can lead to further refinement of our conceptual tools in the analysis of collective intentionality (part 3).

"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 (namely, Michael Bratman, Margaret Gilbert, Philip Pettit, John R. Searle and Raimo Tuomela) 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 (MLA) are theories of shared agency based on individuals’ attitudes and actions, group-level accounts (GLA) 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.

Together we can often achieve things that are impossible to do on our own. We can prevent something bad from happening, or we can produce something good, even if none of us could do it by ourselves. But when are we morally required to do something of moral importance together with others? This book develops an original theory of collective moral obligations. These are obligations that individual moral agents hold jointly but not as unified collective agents. The theory does not stipulate a new type of moral obligation but rather suggests that to think of some of our obligations as joint or collective is the best way of making sense of our intuitions regarding collective moral action problems. Where we have reason to believe that our efforts are most efficient as part of a collective endeavor, we may incur collective obligations together with others who are similarly placed as long as we are able to establish compossible individual contributory strategies towards that goal. The book concludes with a discussion of 'massively shared obligations' to major-scale moral problems such as global poverty. Getting Out Act Together: A Theory of Collective Moral Obligations will appeal to researchers and advanced students working in moral, political and social philosophy, philosophy of action, social epistemology and philosophy of social science.

The Routledge Handbook of Collective Responsibility comprehensively addresses questions about who is responsible and how blame or praise should be attributed when human agents act together. Such questions include: Do individuals share responsibility for the outcome or are individuals responsible only for their contribution to the act? Are individuals responsible for actions done by their group even when they don’t contribute to the outcome? Can a corporation or institution be held morally responsible apart from the responsibility of its members? The Handbook’s 35 chapters—all appearing here for the first time and written by an international team of experts—are organized into four parts: Part I: Foundations of Collective Responsibility Part II: Theoretical Issues in Collective Responsibility Part III: Domains of Collective Responsibility Part IV: Applied Issues in Collective Responsibility Each part begins with a short introduction that provides an overview of issues and debates within that area and a brief summary of its chapters. In addition, a comprehensive index allows readers to better navigate the entirety of the volume’s contents. The result is the first major work in the field that serves as an instructional aid for those in advanced undergraduate courses and graduate seminars, as well as a reference for scholars interested in learning more about collective responsibility.
