Abstract
Philosophical accounts of moral responsibility are standardly framed by two platitudes. According to them, blame requires the presence of a moral defect in the agent and the absence of excuses. In this chapter, this kind of approach is challenged. It is argued that (a) people sometimes violate moral norms due to performance mistakes, (b) it often appears reasonable to hold them responsible for it, and (c) their mistakes cannot be traced to their moral qualities or to the presence of excuses. In the end, the
implications for discussions of moral responsibility are discussed.
