So, I’m still behind on chores (some laundry on the floor, some more in the dryer, that pile of boxes in the living room, &c.), but allow me to quickly clarify one thing before I get to sleep. (I might have a separate reply for the great-grandparent later.)
the meaning of a word is determined by how it is actually used
Right, and the same word can have different meanings depending on context if it gets used differently in different contexts. Specifically, I perceive the word rationalist as commonly being used with two different meanings:
(1) anyone who seeks methods of systematically correct reasoning, general ways of thinking that produce maps that reflect the territory and use those maps to formulate plans that achieve goals
(2) a member of the particular social grouping of people who read Less Wrong. (And are also likely to read Slate Star Codex, be worried about existential risk from artificial intelligence, be polyamorous and live in Berkeley, CA, &c.)
I intended my “as an aspiring epistemic rationalist” to refer to the meaning rationalist(1), whereas I read your “other rationalists disagreeing with you” to refer to rationalist(2).
An analogy: someone who says, “As a Christian, I cannot condone homosexual ‘marriage’” is unlikely to be moved by the reply, “But lots of Christians at my liberal church disagree with you”. The first person is trying to be a Christian(1) as they understand it—one who accepts Jesus Christ as their lord and savior and adheres to the teachings of the Bible. The consensus of people who are merely Christian(2)—those who belong to a church—is irrelevant if that church is corrupt and has departed from God’s will.
Hope this helps.
one function of “as an aspiring epistemic rationalist” in what you wrote is to encourage readers who also think of themselves that way to feel bad about disagreeing
I mean, they should feel bad if and only if feeling bad helps them be less wrong.
Yup, all understood. (I think in practice any given use of the word is likely to have a bit of both meanings in it, with or without concomitant equivocation.)
[EDITED to add:] Maybe it’s worth saying a little about your analogy. To whatever extent the analogy does more than merely illustrate your distinction between rationalist-1 and rationalist-2 (and I take it it is intended to do a little more, since the distinction was perfectly clear without it), it seems that you see yourself as being in something like the position of the Hypothetical Evangelical, asking us all “do ye not therefore err, because ye know not the Sequences, neither the power of rationality?”. That of course is why I dedicated most of my comment to arguing against your actual claim, that those who seek truth through clear thinking must choose their concept-boundaries without any considerations other than minimizing average description length. And my position is a bit like one I remember holding not infrequently in the past, when I was (alas) a moderately-evangelical Christian: I can see how you see the Sequences as supporting your position, but I don’t think that’s the only or the best way to interpret the relevant bits of the Sequences, and to whatever extent Eliezer was saying the same thing as you I’m afraid I think that Eliezer was wrong. (Yes, I am suggesting, tongue somewhat but not wholly in cheek, a parallel between some Christians’ equivocation between “God’s will” and “what is written in the bible” and your appeal to the authority of Eliezer’s posts about word and concepts when arguing for what seem to me inadvisably-extreme positions on how rationalists should use words.)
Incidentally, I’m aware that that’s now twice in a row that I’ve responded very briefly and then edited in more substantive comments. I promise I’m not doing it out of any wish to deceive or anything like that. It’s just that sometimes I’m right on the fence about how much it’s worth saying.
