 Another problem arguably shared by all three approaches is (e), that of being self-effacing. An ethical theory is self-effacing if, roughly, whatever it claims justifies a particular action, or makes it right, had better not be the agent’s motive for doing it. Michael Stocker (1976) originally introduced it as a problem for deontology and consequentialism. He pointed out that the agent who, rightly, visits a friend in hospital will rather lessen the impact of his visit on her if he tells her either that he is doing it because it is his duty or because he thought it would maximize the general happiness. But as Simon Keller observes, she won’t be any better pleased if he tells her that he is visiting her because it is what a virtuous agent would do, so virtue ethics would appear to have the problem too (Keller 2007). However, virtue ethics’ defenders have argued that not all forms of virtue ethics are subject to this objection (Pettigrove 2011) and those that are are not seriously undermined by the problem (Martinez 2011).
