Faces of IntentionSelected Essays on Intention and Agency

This collection of essays by one of the most prominent and internationally respected philosophers of action is concerned with deepening our understanding of intention and agency. 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 Castaiieda, J. David Velleman, Christine Korsgaard, Harry Frankfurt, and P. F. Strawson. This collection will be a valuable resource for a wide range of philosophers and their students and will also be of interest to social and developmental psychologists, AI researchers, and game and decision theorists.

Michael E. Bratman is Howard H. and Jessie T. Watkins University Professor of Philosophy at Stanford University.

Acknowledgments

I have tried to acknowledge my many, many intellectual debts in each of the essays. I would like also to express my gratitude to a number of institutions for their support of my research. Some of my work has been generously supported by the Center for the Study of Language and Information. Several essays were written while I was a Fellow at the Stanford University Humanities Center. I learned much from discussions with participants in the National Endowment for the Humanities Summer Seminar for College Teachers that I directed in 1993. I made some progress while I was Olmsted Visiting Professor in the Yale University Program on Ethics, Politics and Economics. Most recently, a fellowship at the Center for Advanced Study in Behavioral Sciences has provided the occasion for calm reflection needed to bring this project to completion. I am grateful for financial support provided by the Andrew W. Mellon Foundation. Throughout I have benefited greatly from the stimulation and support of colleagues and students in the Stanford University Philosophy Department. My deepest thanks go to my family - Susan, Gregory, and Scott. Without their support this book simply would not have been written. All essays other than essay 1 have been previously published. I have updated references, corrected an occasional stylistic infelicity, and have also made minor changes in essays 2, 6, and 10. Essay 7 has been substantially shortened and somewhat revised. Some of these changes have been made to decrease repetition. A good deal of repetition

remains, however. This is in part because I wanted to ensure that each essay continues to stand on its own, and in part because (with the exception of essay 7) I did not want to make large changes to essays that had already appeared and been the target of discussion. The notes in essay 10 have been renumbered to conform with the style of the other papers. In each case I am very grateful for permission to reprint the essays.

1Introduction: Planning Agents in a Social World

We are planning agents. Our purposive activity is typically embedded in multiple, interwoven quilts of partial, future-directed plans of action. We settle in advance on such plans of action, fill them in, adjust them, and follow through with them as time goes by.
