The Handbook on Collective Intentionality brings together experts across a wide range of subjects concerned with the study of intentionality in the social context. "This superb handbook provides a broad survey of the scope and direction of the rapidly developing field of collective intentionality. Itself a collective enterprise by a body of international experts, this work is a must read for every student, teacher and researcher working on this exciting new interdisciplinary domain." - John D. Greenwood, CUNY Graduate Center "This collection stands as an excellent record of the state of current research on the subject of collective intentionality. One welcomes the summary statements by some prominent figures in the field of their own seminal contributions, and one is instructed into the directions in which further inquiry is now proceeding. Each of the contributions is well informed, clear, and cogently argued. Taken together they reveal a wider significance of collective intentionality not only in human inquiry but in human affairs." -Carol Rovane, Columbia University
