 A naturalist may want to challenge premise (2) by finding some other strategy to explain human dignity. Michael Martin (2002), for example, has tried to suggest that moral judgments can be analyzed as the feelings of approval or disapproval of a perfectly impartial and informed observer. Linville (2009) objects that it is not clear how the feelings of such an observer could constitute the intrinsic worth of a person, since one would think that intrinsic properties would be non-relational and mind-independent. In any case, Linville notes that a “Euthyphro” problem lurks for such an ideal observer theory, since one would think that such an observer would judge a person to be intrinsically valuable because the person has intrinsic value.
