Accounts of moral responsibility can be divided into those that claim that attributability of an act, omission, or attitude to an agent is sufficient for responsibility for it, and those which hold that responsibility depends crucially on choice. I argue that accounts of the first, attributionist, kind fail to make room for the relatively stringent epistemic conditions upon moral responsibility, and that therefore an account of the second, volitionist, kind ought to be preferred. I examine the various arguments advanced on (...) behalf of attributionist accounts, and argue that for each of them volitionism has a reply that is in every case at least as, and often more, persuasive. Most significantly, only volitionism can accommodate the intuitively important distinction between the bad and the blameworthy. (shrink)
