From Individual To Collective Intentionality

Acting together requires collective intentions. The contributions to this volume seek to critically assess or to enrich theories of collective intentionality by exploring topics such as collective belief, mutual coordination, and the explanation of group behavior.

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

Social ontology, in its broadest sense, is the study of the nature of social reality, including collective intentions and agency. The starting point of Tuomela's account of collective intentionality is the distinction between thinking and acting as a private person ("I-mode") versus as a "we-thinking" group member ("we-mode"). The we-mode approach is based on social groups consisting of persons, which may range from simple task groups consisting of a few persons to corporations and even to political states. Tuomela extends the we-mode notion to cover groups controlled by external authority. Thus, for instance, cooperation and attitude formation are studied in cases where the participants are governed "from above" as in many corporations. The volume goes on to present a systematic philosophical theory related to the collectivism-versus-individualism debate in the social sciences. A weak version of collectivism (the "we-mode" approach) depends on group-based collective intentionality. We-mode collective intentionality is not individualistically reducible and is needed to complement individualistic accounts in social scientific theorizing. The we-mode approach is used in the book to account for collective intention and action, cooperation, group attitudes, and social practices and institutions, as well as group solidarity. Tuomela establishes the first complete theory of group reasons (in the sense of members' reasons for participation in group activities). The book argues in terms of game-theoretical group-reasoning that the kind of weak collectivism that the we-mode approach involves is both conceptually and rational-functionally different from what an individualistic approach ("pro-group I-mode" approach) entails.

The present volume contains a selection of papers presented at the Fifth Conference on Collective Intentionality held at the University of Helsinki August 31 to September 2, 2006 and two additional contributions. The common aim of the papers is to explore the structure of shared intentional attitudes, and to explain how they underlie the social, cultural and institutional world. The contributions to this volume explore the phenomenology of sharedness, the concept of sharedness, and also various aspects of the structure of collective intentionality in general, and of the intricate relations between sharedness and normativity in particular. Concepts of Sharedness shows how rich and lively the philosophical research focused on the analysis of collective intentionality has become, and will provide further inspiration for future work in this rapidly evolving field.

This volume features a critical evaluation of the recent work of the philosopher, Prof. Raimo Tuomela and it also offers it offers new approaches to the collectivism-versus-individualism debate. It specifically looks at Tuomela's book Social Ontology and its accounts of collective intentionality and related topics. The book contains eight essays written by expert contributors that present different perspectives on Tuomela’s investigation into the philosophy of sociality, social ontology, theory of action, and (philosophical) decision and game theory. In addition, Tuomela himself gives a comprehensive response to each essay and defends his theory in terms of the new arguments presented here. Overall, readers will gain a deeper insight into group reasoning and the "we-mode" approach, which is used to account for collective intention and action, cooperation, group attitudes, social practices, and institutions as well as group solidarity. This book will be of interest to a wide range of readers and graduate students and researchers interested in contemporary philosophy of sociality, sociological theory, social ontology as well as the philosophy of mind, decision and game theory, and cognitive science. Tuomela’s book stands as a model of excellence in social ontology, an especially intractable field of philosophical inquiry that benefits conspicuously from the devotion of Tuomela’s keen philosophical mind. His book is must reading in social ontology. J. Angelo Corlett, Julia Lyons Strobel

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.

The Routledge Handbook of Collective Intentionality provides a wide-ranging survey of topics in a rapidly expanding area of interdisciplinary research. It consists of 36 chapters, written exclusively for this volume, by an international team of experts. What is distinctive about the study of collective intentionality within the broader study of social interactions and structures is its focus on the conceptual and psychological features of joint or shared actions and attitudes, and their implications for the nature of social groups and their functioning. This Handbook fully captures this distinctive nature of the field and how it subsumes the study of collective action, responsibility, reasoning, thought, intention, emotion, phenomenology, decision-making, knowledge, trust, rationality, cooperation, competition, and related issues, as well as how these underpin social practices, organizations, conventions, institutions and social ontology. Like the field, the Handbook is interdisciplinary, drawing on research in philosophy, cognitive science, linguistics, legal theory, anthropology, sociology, computer science, psychology, economics, and political science. Finally, the Handbook promotes several specific goals: (1) it provides an important resource for students and researchers interested in collective intentionality; (2) it integrates work across disciplines and areas of research as it helps to define the shape and scope of an emerging area of research; (3) it advances the study of collective intentionality.
