I was one of the ones disputing in those comments, but I have to admit that g's "The absolute is an uncle" example stopped me short. I developed the "logs of the universe" theory in response to that, but I'm not sure how good a response it was - hence footnote 2, about how it was easy in practice but kind of hard in theory.

Emotivism is very relevant here and I was thinking of making a followup post on it. Good catch.
