 Another problem for virtue ethics, which is shared by both utilitarianism and deontology, is (f)  “the justification problem.”  Abstractly conceived, this is the problem of how we justify or ground our ethical beliefs, an issue that is hotly debated at the level of metaethics. In its particular versions, for deontology there is the question of how to justify its claims that certain moral rules are the correct ones, and for utilitarianism of how to justify its claim that all that really matters morally are consequences for happiness or well-being. For virtue ethics, the problem concerns the question of which character traits are the virtues.
