-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).

-_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, yes, but the thing you have to realize is—
-
-_Everyone else shot first_. 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 Facebook posts of [September 2020](https://www.facebook.com/yudkowsky/posts/10158853851009228) and [February 2021](https://www.facebook.com/yudkowsky/posts/10159421750419228). So, that's nice.
-
-[TODO: although I think even with the note, in practice, people are going to keep citing "... Not Man for the Categories" in a way that doesn't understand how the note undermines the main point]
-
-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.
