I’ll give it a try. A human’s mind and preferences might be influenced by cultural things like books and TV, and they might be influenced by non-cultural things like parasites. (And of course a lot of people will be influenced by both.) I can’t think of a reason to include the former in CEV and exclude the latter that feels non-arbitrary to me, so I don’t feel as if parasitically modified brains warrant different treatment, such as altering CEV to cover the space of all possible humans. My gut evaluates the prospect of parasite-driven brains as just another kind of human brain. (I’m presuming as well that CEV as currently formulated is just meant to cover existing humans, not all possible humans.) That makes me content to apply CEV to existing humans only—I don’t feel I have to try to account for brain changes due to culture or parasites or what have you by expanding it to incorporate all of brain space.
I am not sure I follow your last sentence. Can you elaborate?
