 Ideal Dispositionalist views also avoid the Missing Rigidity Problem. Depending on the details, it may suffice to idealize the subject of the sentiments: maybe no impartial spectator would approve of slavery, even if the majority of people were to have a pro-slavery sensibility. In case the idealization process is path-dependent (so that the outcome depends on the unidealized initial sentiments of the subject), Ideal Dispositionalists may make a rigidification move (Wiggins 1987: 206). They can say that the starting point for idealization is constituted by actually normal sentiments, which include a strong desire not to be at the mercy of the good will of others, among others. Thus, rigidified ideal observers would disapprove of slavery, even if it became statistically normal to approve of it. Peter Railton (2003) objects to rigidification, because for him what is intrinsically good or bad for someone is relational, dependent on the match between their responses and their objects, much as sweetness and bitterness are. Changes in people’s sensibilities would change what’s good (or sweet) for them. Still, something like cruelty wouldn’t become right even if it were generally approved of, since for Railton, its wrongness hangs on badness of its consequences rather than our disapproval of it, and pain that people are averse to would still be bad for them.
