I'll do some reading and see if I can figure out what your last paragraph means; thanks for the link.
Ah, have you not actually read through the whole sequence yet? I don't recommend reading it out of order, and I do recommend reading the whole thing. Mainly because some people in this thread (and elsewhere) are giving completely wrong summaries of it, so you would probably get a much clearer picture of it from the original source.
I've read the series all the way through, twice, but large parts of it didn't make sense to me. By reading the linked post again, I'm hoping to combine what you've said with what it says and come to some understanding.
In You Provably Can't Trust Yourself, Eliezer tried to figured out why his audience didn't understand his meta-ethics sequence even after they had followed him through philosophy of language and quantum physics. Meta-ethics is my specialty, and I can't figure out what Eliezer's meta-ethical position is. And at least at this point, professionals like Robin Hanson and Toby Ord couldn't figure it out, either.
Part of the problem is that because Eliezer has gotten little value from professional philosophy, he writes about morality in a highly idiosyncratic way, using terms that would require reading hundreds of posts to understand. I might understand Eliezer's meta-ethics better if he would just cough up his positions on standard meta-ethical debates like cognitivism, motivation, the sources of normativity, moral epistemology, and so on. Nick Beckstead recently told me he thinks Eliezer's meta-ethical views are similar to those of Michael Smith, but I'm not seeing it.
If you think you can help me (and others) understand Eliezer's meta-ethical theory, please leave a comment!
Update: This comment by Richard Chappell made sense of Eliezer's meta-ethics for me.
