Without commenting on whether this presentation matches the original metaethics sequence (with which I disagree), this summary argument seems both unsupported and unfalsifiable.
Would this be an accurate summary of what you think is the meta-ethics sequence? I feel that you captured the important bits but I also feel that we disagree on some aspects:
V(Elves, ) = Christmas spirity
V(Pebblesorters, ) = primality
V(Humans, _ ) = morality
If V(Humans, Alice) =/= V(Humans, ) that doesn't make morality subjective, it is rather i...
Unpacking "should" as " morally obligated to" is potentially helpful, so inasmuch as you can give separate accounts of "moral" and "obligatory".
The elves are not moral. Not just because I, and humans like me happen to disagree with them, no, certainly not. The elves aren’t even trying to be moral. They don’t even claim to be moral. They don’t care about morality. They care about “The Christmas Spirit,” which is about eggnog and stuff
That doesn't generalise to the point that non humans have no morality. You have m...
Morality binds and blinds. People derive moral claims from emotional and intuitive notions. It can feel good and moral to do amoral things. Objective morality has to be tied to evidence what really is human wellbeing; not to moral intuitions that are adaptions to the benefit of ones ingroup; or post hoc thought experiments about knowledge.
I don't know. I wonder if some extra visualization would help.
Would you help catch the children so that their parents could eat them? If they pleaded with you, would you really think "if you were to live, you would one day agree this was good, therefore it is good, even though you don't currently believe it to be?"
Why say the important desire is the one the child will one day have, instead of the one that the adult used to have?
I would certainly be less interested in aliens obtaining what is good for them, than in humans obtaining what is good for them. However, that said, the basic response (given Eliezer's stipulations), is yes, I would, and yes I would really think that.
The adult has not only changed his desire, he has changed his mind as well, and he has done that through a normal process of growing up. So (again given Eliezer's stipulations), it is just as reasonable to believe the adults here as it is to believe human adults. It is not a question of talking about whose desire is important, but whose opinion is correct.
