Most of the people who are most likely to think that EY's positions on things are plainly false probably don't bother registering here to say so.
True, but I still wouldn't expect sharp disagreement with Eliezer to be so rare. One contributing factor may be that Eliezer at least appears to be so confident in so many of his positions, and does not put many words of uncertainty into his writing about theoretical issues.
When I first found this site, I read through all the OB posts chronologically, rather than reading the Sequences as sequences. So I got to see the history of several commenters, many of whom disagreed sharply with EY, with their disagreement evolving over several posts.
They tend to wander off after a while. Which is not surprising, as there is very little reward for it.
So I guess I'd ask this a different way: if you were an ethical philosopher whose positions disagreed with EY, what in this community would encourage you to post (or comment) about your disagreements?
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.
