Sure, agreed: if I tell the PM that thus-and-such is labeled "right," or "moral," or "fleabag," then it will know these things, and it won't care.
I have entirely lost track of why this is important.
Eliezer believes that you desire to do what is right. It is important to remember that what is right has nothing to do with whether you desire it. Moral facts are interesting because they describe our desires, but they would be true even if our desires were different.
In general, these things are useful for programming FAI and evaluating moral arguments. We should not allow our values to drift too far over time. The fact that wireheads want to be wireheaded is not a a valid argument in favour of wireheading. A FAI should try to make reality match what is ri...
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.
