 List and Pettit devote a great deal of their own attention to how we might use our recognition of these obligations, entitlements, and power relations to re-work various institutions in contemporary society. But they do not neglect the question of collective moral blameworthiness. Nor do they simply assume that such blameworthiness follows automatically from group moral agency. Instead they make clear that in order for a group to be morally blameworthy, its actions must be associated with a “grave matter”; the group must have “full knowledge of guilt”; and there must have been “full consent of the will” (List and Pettit 2011, 155). List and Pettit think that these conditions can be met by at least some groups. Are they right?
