+An important thing to appreciate is that the philosophical point I was trying to make has _absolutely nothing to do with gender_. In 2008, Yudkowsky had explained that _for all_ nouns N, you can't define _N_ any way you want, because _useful_ definitions need to "carve reality at the joints."
+
+It [_follows logically_](https://www.lesswrong.com/posts/WQFioaudEH8R7fyhm/local-validity-as-a-key-to-sanity-and-civilization) that, in particular, if _N_ := "woman", you can't define the word _woman_ any way you want. Maybe trans women _are_ women! But if so—that is, if you want people to agree to that word usage—you need to be able to _argue_ for why that usage makes sense on the empirical merits; you can't just _define_ it to be true. And this is a _general_ principle of how language works, not something I made up on the spot in order to attack trans people.
+
+In 2008, this very general philosophy of language lesson was _not politically controversial_. If, in 2018–present, it _is_ politically controversial (specifically because of the fear that someone will try to apply it with _N_ := "woman"), that's a _problem_ for our whole systematically-correct-reasoning project! What counts as good philosophy—or even good philosophy _pedagogy_—shouldn't depend on the current year!
+
+There is a _sense in which_ one might say that you "can" define a word any way you want. That is: words don't have intrinsic ontologically-basic meanings. We can imagine an alternative world where people spoke a language that was _like_ the English of our world, except that they use the word "tree" to refer to members of the empirical entity-cluster that we call "dogs" and _vice versa_, and it's hard to think of a meaningful sense in which one convention is "right" and the other is "wrong".
+
+But there's also an important _sense in which_ we want to say that you "can't" define a word any way you want. That is: some ways of using words work better for transmitting information from one place to another. It would be harder to explain your observations from a trip to the local park in a language that used the word "tree" to refer to members of _either_ of the empirical entity-clusters that the English of our world calls "dogs" and "trees", because grouping together things that aren't relevantly similar like that makes it harder to describe differences between the wagging-animal-trees and the leafy-plant-trees.
+
+If you want to teach people about the philosophy of language, you should want to convey _both_ of these lessons, against naïve essentialism, _and_ against naïve anti-essentialism. If the people who are widely respected and trusted [(almost worshipped)](https://www.lesswrong.com/posts/Ndtb22KYBxpBsagpj/eliezer-yudkowsky-facts) as the leaders of the systematically-correct-reasoning community, [_selectively_](https://www.lesswrong.com/posts/AdYdLP2sRqPMoe8fb/knowing-about-biases-can-hurt-people) teach _only_ the words-don't-have-intrinsic-ontologically-basic-meanings part when the topic at hand happens to be trans issues (because talking about the carve-reality-at-the-joints part would be [politically suicidal](https://www.lesswrong.com/posts/DoPo4PDjgSySquHX8/heads-i-win-tails-never-heard-of-her-or-selective-reporting)), then people who trust the leaders are likely to get the wrong idea about how the philosophy of language works—even if [the selective argumentation isn't _conscious_ or deliberative](https://www.lesswrong.com/posts/sXHQ9R5tahiaXEZhR/algorithmic-intent-a-hansonian-generalized-anti-zombie) and [even if every individual sentence they say permits a true interpretation](https://www.lesswrong.com/posts/MN4NRkMw7ggt9587K/firming-up-not-lying-around-its-edge-cases-is-less-broadly).
+
+(As it is written of the fourth virtue of evenness, ["If you are selective about which arguments you inspect for flaws, or how hard you inspect for flaws, then every flaw you learn how to detect makes you that much stupider."](https://www.yudkowsky.net/rational/virtues))
+
+_Was_ it a "political" act for me to write about the cognitive function of categorization on the robot-cult blog with non-gender examples, when gender was secretly ("secretly") my _motivating_ example? In some sense, I guess? But if so, the thing you have to realize is—
+
+_Everyone else shot first_. That's not just my subjective perspective; the timestamps back me up here: my ["... To Make Predictions"](/2018/Feb/the-categories-were-made-for-man-to-make-predictions/) (February 2018) was a _response to_ Alexander's ["... Not Man for the Categories"](https://slatestarcodex.com/2014/11/21/the-categories-were-made-for-man-not-man-for-the-categories/) (November 2014). My philosophy-of-language work on the robot-cult blog (April 2019–January 2021) was (stealthily) _in response to_ Yudkowsky's November 2018 Twitter thread. When I started trying to talk about autogynephilia with all my robot cult friends in 2016, I _did not expect_ to get dragged into a multi-year philosophy-of-language crusade! That was just _one branch_ of the argument-tree that, once begun, I thought should be easy to _definitively settle in public_ (within our robot cult, whatever the _general_ public thinks).
+
+I guess by now the branch is as close to settled as it's going to get? Alexander ended up [adding an edit note to the end of "... Not Man to the Categories" in December 2019](https://archive.is/1a4zV#selection-805.0-817.1), and Yudkowsky would [go on to clarify his position on the philosophy of language in September 2020](https://www.facebook.com/yudkowsky/posts/10158853851009228). So, that's nice. But I will confess to being quite disappointed that the public argument-tree evaluation didn't get much further, much faster? The thing you have understand about this whole debate is—
+
+_I need the correct answer in order to decide whether or not to cut my dick off_. As I've said, I _currently_ believe that cutting my dick off would be a _bad_ idea. But that's a cost–benefit judgement call based on many _contingent, empirical_ beliefs about the world. I'm obviously in the general _reference class_ of males who are getting their dicks cut off these days, and a lot of them seem to be pretty happy about it! I would be much more likely to go through with transitioning if I believed different things about the world—if I thought my beautiful pure sacred self-identity thing were a brain-intersex condition, or if I still believed in my teenage psychological-sex-differences denialism (such that there would be _axiomatically_ no worries about fitting with "other" women after transitioning), or if I were more optimistic about the degree to which HRT and surgeries approximate an actual sex change.
+
+In that November 2018 Twitter thread, [Yudkowsky wrote](https://archive.is/y5V9i):
+
+> _Even if_ somebody went around saying, "I demand you call me 'she' and furthermore I claim to have two X chromosomes!", which none of my trans colleagues have ever said to me by the way, it still isn't a question-of-empirical-fact whether she should be called "she". It's an act.
+
+This seems to suggest that gender pronouns in the English language as currently spoken don't have effective truth conditions. I think this is false _as a matter of cognitive science_. If someone told you, "Hey, you should come meet my friend at the mall, she is really cool and I think you'll like her," and then the friend turned out to look like me (as I am now), _you would be surprised_. (Even if people in Berkeley would socially punish you for _admitting_ that you were surprised.) The "she ... her" pronouns would prompt your brain to _predict_ that the friend would appear to be female, and that prediction would be _falsified_ by someone who looked like me (as I am now). Pretending that the social-norms dispute is about chromosomes was a _bullshit_ [weakmanning](https://slatestarcodex.com/2014/05/12/weak-men-are-superweapons/) move on the part of Yudkowsky, [who had once written that](https://www.lesswrong.com/posts/qNZM3EGoE5ZeMdCRt/reversed-stupidity-is-not-intelligence) "[t]o argue against an idea honestly, you should argue against the best arguments of the strongest advocates[;] [a]rguing against weaker advocates proves _nothing_, because even the strongest idea will attract weak advocates." Thanks to the skills I learned from Yudkowsky's _earlier_ writing, I wasn't dumb enough to fall for it, but we can imagine someone otherwise similar to me who was, who might have thereby been misled into making worse life decisions.
+
+[TODO: ↑ less aggressive about E.Y.'s motives, just focus on consequences for people like me who trust him]
+
+If this "rationality" stuff is useful for _anything at all_, you would _expect_ it to be useful for _practical life decisions_ like _whether or not I should cut my dick off_.
+
+In order to get the _right answer_ to that policy question (whatever the right answer turns out to be), you need to _at minimum_ be able to get the _right answer_ on related fact-questions like "Is late-onset gender dysphoria in males an intersex condition?" (answer: no) and related philosophy-questions like "Can we arbitrarily redefine words such as 'woman' without adverse effects on our cognition?" (answer: no).
+
+At the cost of _wasting three years of my life_, we _did_ manage to get the philosophy question right! Again, that's nice. But compared to the [Sequences-era dreams of changing the world](https://www.lesswrong.com/posts/YdcF6WbBmJhaaDqoD/the-craft-and-the-community), it's too little, too slow, too late. If our public discourse is going to be this aggressively optimized for _tricking me into cutting my dick off_ (independently of the empirical cost–benefit trade-off determining whether or not I should cut my dick off), that kills the whole project for me. I don't think I'm setting [my price for joining](https://www.lesswrong.com/posts/Q8evewZW5SeidLdbA/your-price-for-joining) particularly high here?
