The discussion with eridu was probably worth ending, but I saw someone say it was the best discussion of those issues they'd ever seen, and I'd said so myself independently in a location that I've promised not to link to.

I am very impressed with LW that we managed to make that happen.

Did you learn something useful or interesting, or were you just impressed that the discussion remained relatively civil? If the former, can you summarize what you learned?

Comment author: NancyLebovitz 14 September 2012 03:45:57PM 3 points [-]

I learned something that might turn out to be useful.

I got a bit of perspective on the extent to which I amplify my rage and distrust at SJ-related material (I had a very rough time just reading a lot of racefail)-- I'm not sure what I want to do with this, but it's something new at my end.

The civility of the discussion is very likely to have made this possible.

I'm having trouble understanding this sentence. First, I guess SJ = "social justice" and racefail = "a famously controversial online discussion that was initially about writing fictional characters who are people of color"? But what does it mean to amplify your rage and distrust at some material? Do you mean some parts of the SJ-related materials made you angry and distrustful? Distrustful of who? Which parts made you feel that way? Why? And how did the eridu discussion help you realize the extent?

I'm curious myself. I honestly didn't see anything useful said. (Perhaps I just took all the valid points for granted as obvious?)

That discussion sucked. I was appalled at LW when I came back after a few hours and still "patriarchy" "abuse" etc hadn't been tabooed.

You could have asked for them to be tabooed.

Thanks.

That's interesting-- as I recall, requests for words to be tabooed are usually at least somewhat honored.

Comment author: shminux 14 September 2012 08:00:13PM 1 point [-]

Not in my experience.

Comment author: [deleted] 14 September 2012 08:13:57PM 4 points [-]

You ask for "exist" "true" etc to be tabooed, which is hard. Assuming they even try, it would take a while to wade thru all the philosophical muck and actually get to something, by which point the moment has passed.

My usual response to requests for "X exists" to be tabooed is to start talking about reliably predicting future experiences E2 in a range of contexts C (as C approaches infinity) consistent with the past experiences E1 which led me to to put X in my model in the first place. If someone wants to talk about E2 being reliably predictable even though X "doesn't really exist", it's not in the least bit clear to me what they're talking about.

Thanks! This is a very useful explanation / reduction / taboo.

It also sheds some light and helped me understand quite a bit more, I believe, on this whole "instrumentalism" business some people here seem to really want to protect.

(link is just in case someone misunderstands this as an accusation of "Politics!")

You're welcome. I vaguely remember being involved in an earlier discussion that covered this idea at greater length, wherein I described myself as a compatibilist when it comes to instrumentalism, but the obvious google search doesn't find it so perhaps I'm deluded.

Comment author: [deleted] 14 September 2012 08:49:27PM 2 points [-]

Yes. I recently described it as this:

the "right" probability distribution is the one that maximizes the expected utility of an expected utility maximizer using that probability distribution.

reliably predicting future experiences E2 in a range of contexts C (as C approaches infinity) consistent with the past experiences E1 which led me to to put X in my model in the first place.

I wholeheartedly approve of this approach. If more people used it, we would avoid the recurrent unproductive discussions of QM interpretations, qualia and such.

EDIT. Just to clarify, the part saying "put X in my model" is the essential bit to preempt the discussion of "but does it exist outside your model?", since the latter would violate this definition of "exist". such as this statement by our esteemed Kaj Sotala:

why those beings actually have qualia, and don't merely act like it.

Comment author: TheOtherDave 14 September 2012 08:56:36PM *  0 points [-]

Oh, I very much doubt that. But I'd like to think so.

EDIT: I wrote the above before your edit, and don't really understand your edit.

Instrumentalism is pretty unproductive when it comes to answering questions about what really exists.

You ask for "exist" "true" etc to be tabooed, which is hard.

Or at least unusual enough to be brushed aside as "wtf".

Comment author: Wei_Dai 23 September 2012 09:35:20AM *  4 points [-]

There are lots of words that I don't know how to taboo, because I only have a partial and largely intuitive understanding of the concepts I'm referring to by them, and can't fully explain those concepts. Examples: "exist", "truth", "correct", "right", "moral", "rational", "should", "mathematical". I don't think anyone has asked me directly to taboo any of these words, but if someone did, I might ignore the request because I think my time could be better spent trying to communicate with others who seem to already share my understandings of these words.

In the case of "exist", I think that something exists implies that I can care about it and not be irrational. ("care about": for example, have a term for it in my utility function) This seems to at least capture a large part of what I mean when I say something exists, but I'm not sure if "exists" just means (something like) the correct decision theory allows a utility function to have a term for something, or if existence is somehow more fundamental than that and our ability to rationally care about something derives from its existence in that more fundamental sense. Does this make sense?

Well, apparently TheOtherDave is bold enough to give a meaningful definition of "exist". Would you agree with it? If not, what would be a counterexample?

Comment author: Desrtopa 14 September 2012 08:23:22PM 3 points [-]

I'd say that asking people to taboo "true" is very common, in certain circles outside Less Wrong. That's why Eliezer wrote The Simple Truth.

Comment author: shminux 14 September 2012 08:31:33PM *  4 points [-]

Unfortunately, the last sensible (to me) exchange in it was around

“Mark, I don’t think you understand the art of bucketcraft,” I say. “It’s not about using pebbles to control sheep. It’s about making sheep control pebbles. In this art, it is not necessary to begin by believing the art will work. Rather, first the art works, then one comes to believe that it works.”

After that the instrumentalist argument got heavily strawmanned:

“Ah! Now we come to the root of the problem,” says Mark. “What’s this so-called ‘reality’ business? I understand what it means for a hypothesis to be elegant, or falsifiable, or compatible with the evidence. It sounds to me like calling a belief ‘true’ or ‘real’ or ‘actual’ is merely the difference between saying you believe something, and saying you really really believe something.”

It gets worse after that, until EY kills the offending in-strawman-talist with some gusto.

Would you be satisfied if I tabooed "Fs exist" as "The set of all Fs is non-empty"?

Comment author: shminux 14 September 2012 09:07:19PM 2 points [-]

I dislike fake formalizations. TheOtherDave's approach makes a lot more sense to me.
