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.
The standard debates ask wrong questions, there's little point answering them, you'd spend all the time explaining your preferred ways of disambiguating the hopelessly convoluted standard words. Unsurprisingly, Eliezer's metaethics doesn't actually solve all of decision theory, so it makes a lot of steps in the right direction, while still necessarily leaving you confused even if you understood every step. You'd need to ask more specific questions, clarification for specific claims. I agree that regurgitating a body of knowledge usually helps it compost, but a mere summary probably won't do the trick.
