There seems to be a widespread impression that the metaethics sequence was not very successful as an explanation of Eliezer Yudkowsky's views. It even says so on the wiki. And frankly, I'm puzzled by this... hence the "apparently" in this post's title. When I read the metaethics sequence, it seemed to make perfect sense to me. I can think of a couple things that may have made me different from the average OB/LW reader in this regard:
- I read Three Worlds Collide before doing my systematic read-through of the sequences.
- I have a background in academic philosophy, so I had a similar thought to Richard Chapell's linking of Eliezer's metaethics to rigid designators independently of Richard.
No Universally Compelling Arguments has been put to me as a decisive refutation of Moral Realism, by somebody who thought the LW line was anti-realist. It isn't a decisive refutation because no (non strawman) realist thinks there are arguments that could compel an irrational person, an insane person, an very unintelligent person, and so on. Moral realists only need to argue that moral truths are independently discoverable by suitably motivated and equipped people, like mathematical truths (etc).
