 Another option is to hold that there are partial norms, but those partial norms are themselves justified on impartial grounds. This can be spelled out in a variety of different ways. Consider Marcia Baron’s defense of impartiality, where she notes that critics of impartiality are mistaken because they confuse levels of justification: “Critics suppose that impartialists insisting on impartiality at the level of rules or principles are committed to insisting on impartiality at the level of deciding what to do in one’s day-to-day activities” (Baron 1991). This is a mistake because impartialists can justify partial norms by appealing to impartial rules or principles. She is correct about this. Even Jeremy Bentham believed, for example, that the principle of utility ought not be applied in every case, though he mainly appealed to efficiency costs of using the principle all the time. But one can appeal to other considerations.  Frank Jackson uses an analogy with predators to argue that partial norms are strategies for maximizing the good, they offer the best chance of actually doing so given our limitations (Jackson 1991).  Similarly, a Kantian such as Tom Hill, jr., as Baron notes, can argue that impartiality is part of an ideal, and ought not govern our day-to-day lives (Hill 1987). Does this alienate people from others? The typical mother shows the right amount of preference for her child, let’s say, but doesn’t herself think that this is justified on the basis of promoting the good, for example. A friend visits another in the hospital and also does not view the partiality as justified by any further principles.  But this is no more alienating than someone being able to make good arguments and criticize bad ones without a knowledge of inference rules. Maybe it is better to have an awareness of the underlying justification, but for some theories even that is debatable. For an objective theorist (see below) it may be that knowing the underlying justification can interfere with doing the right thing, in which case it is better not to know. For some theorists, however, such as neo-Aristotelian virtue ethicists, a person is not truly virtuous without such knowledge and understanding, though Rosalind Hursthouse (1999) does not make this a requirement of right action.
