Our aim in this paper is to put the concept of moral responsibility under a microscope. At the lowest level of magnification, it appears unified. But Gary Watson has taught us that if we zoom in, we will find that moral responsibility has two faces: attributability and accountability. Or, to describe the two faces in different terms, there is a difference between being responsible and holding responsible. It is one thing to talk about the connection the agent has with her (...) action; it is quite another to talk about the potential interaction the agent might have with her moral community. It turns out, though, that the faces of moral responsibility can themselves be viewed under an even higher level of magnification. If moral responsibility has two faces, then our aim in this paper is to examine their features. To do so reveals subtle distinctions in our concept of moral responsibility and its interaction with surrounding issues that, we argue, can help illuminate various debates in the literature. (shrink)
