This question has always bothered me, but now after thinking about it a lot I finally have a clear answer: rationalism is the belief that Eliezer Yudkowsky is the rightful caliph.
This is a joke taken out of its context in the article. I think the line should be replaced with (...) if you want to leave the idea of [something was here in the original article].
I'm not motivated enough to fight over it. My arguments are :
- it lacks the context of a whole section of the article
- it could be taken out of context by those who consider us outgroup and
- even more so when it's there on the wiki on the site where the movement began tribening
- i'd prefer if scott hadn't formulated it this way because i find the idea of caliph eliezer fucking terrifying, and since the movement has that funny habit of engaging with its critics as if they were part of it, a more accurate, albeit less funny, formulation would have been "rationalism is the movement that discusses whether the rightful caliph is Eliezer Yudkowsky."
