In addition to asking what attitudes toward death are appropriate, we might ask what attitude we ought to have. Some might think that we ought to have those (and only those) attitudes that are appropriate. However, it is possible for an attitude toward death to be appropriate and yet be an attitude that one ought not to have. [emboldening mine] For example, it might be entirely appropriate to be deeply depressed about the appalling fact that one is going to die, and yet there might be strong, prudential reasons not to become this morose. One might simply make one’s life worse by adopting an appropriate attitude.
I still can't distinguish between the 'appropriate' vs. unwelcome saddening attitude. Even if I judge appropriateness as variable (and not binary), mustn't adopting a more Panglossian attitude be less appropriate, as it self-deceives?
