[Another post I'm working on reminded me of this note from last September that I never got around to posting...]
Is philosophy itself alienating? Excessive concern to achieve the 'view from nowhere' seems like an occupational hazard. Especially if one embraces an 'ideal agent'-type metaethic, this may lead to constantly second-guessing oneself: "would others ideally endorse this?" (Would I?) Perfection is too high a standard to try to live up to. But it's kind of hard to ignore if you spend all day thinking about it!
One worry is that many of our actual sentiments might not be expected to survive the idealization process. Yet ignoring or suppressing them may not be such a good idea. Someone in class today mentioned the 'bad squash loser' case: ideally, the loser should walk over to graciously congratulate the other player. But suppose that, due to his anger, were he to try he would more likely lash out violently. So he really should just walk away and cool off. That at least shows why we can't just ignore our contingent flaws. Is there a similarly clear argument against suppressing unwelcome emotions (e.g. if the squash loser were capable of distancing himself from his anger)? It seems a non-obvious empirical question what the consequences of this are likely to be. [I made a similar point in my recent post on the question whether to attempt to reshape a non-conforming child's gender preferences.]
A second worry arises from the concern for universal convergence. Many of our tastes may be thought idiosyncratic or merely 'subjective', but it would be unfortunate to devalue them for that reason alone. Perhaps we can resolve this by taking tastes as 'given', exempt from rational criticism, and recognize as universalizable the general desire to derive enjoyment from one's tastes (whatever they may be). Or, if such subjectivism is too extreme, at least allow for a plurality of standards of good taste.
