 Almost all of those now writing about collective responsibility agree that collective responsibility would make sense if it were merely an aggregative phenomenon. But they disagree markedly about whether collective responsibility makes sense as a non-distributive phenomenon, i.e., as a phenomenon that transcends the contributions of particular group members. In this context, as in many others, skeptics set the agenda. Two claims become crucial. The first is that groups, unlike individuals, cannot form intentions and hence cannot be understood to act or to cause harm qua groups. The second is that groups, as distinct from their individual members, cannot be understood as morally blameworthy in the sense required by moral responsibility.
