 Not surprisingly, these kinds of arguments run into trouble when questions of agency arise. For, while the existence of solidarity and identification may allow us to talk about a group over time and even label its actions morally wrong,they do not allow us to posit the kind of agency that is required of moral responsibility as traditionally understood. For, as Michael Bratman shows in his own work on collective responsibility, the latter requires, not only that individuals share intentions but that they interact. (See especially Bratman 2000).
