+On Discord in January, Kelsey Piper had told me that everyone else experienced their disagreement with me as being about where the joints are and which joints are important, where usability for humans was a legitimate criterion for importance, and it was annoying that I thought they didn't believe in carving reality at the joints at all and that categories should be whatever makes people happy.
+
+I [didn't want to bring it up at the time because](https://twitter.com/zackmdavis/status/1088459797962215429) I was so overjoyed that the discussion was actually making progress on the core philosophy-of-language issue, but ... Scott _did_ seem to be pretty explicit that his position was about happiness rather than usability? If Kelsey _thought_ she agreed with Scott, but actually didn't, that was kind of bad for our collective sanity, wasn't it?
+
+As for the parable about orcs, I thought it was significant that Scott chose to tell the story from the standpoint of non-orcs deciding what [verbal behaviors](https://www.lesswrong.com/posts/NMoLJuDJEms7Ku9XS/guessing-the-teacher-s-password) to perform while orcs are around, rather than the standpoint of the _orcs themselves_. For one thing, how do you _know_ that serving evil-Melkior is a life of constant torture? Is it at all possible, in the bowels of Christ, that someone has given you _misleading information_ about that? Moreover, you _can't_ just give an orc a clever misinterpretation of an oath and have them believe it. First you have to [cripple their _general_ ability](https://www.lesswrong.com/posts/XTWkjCJScy2GFAgDt/dark-side-epistemology) to correctly interpret oaths, for the same reason that you can't get someone to believe that 2+2=5 without crippling their general ability to do arithmetic. We weren't not talking about a little "white lie" that the listener will never get to see falsified (like telling someone their dead dog is in heaven); the orcs _already know_ the text of the oath, and you have to break their ability to _understand_ it. Are you willing to permanently damage an orc's ability to reason, in order to save them pain? For some sufficiently large amount of pain, surely. But this isn't a choice to make lightly—and the choices people make to satisfy their own consciences, don't always line up with the volition of their alleged beneficiaries. We think we can lie to save others from pain, without ourselves _wanting to be lied to_. But behind the veil of ignorance, it's the same choice!
+
+I _also_ had more to say about philosophy of categories: I thought I could be more rigorous about the difference between "caring about predicting different variables" and "caring about consequences", in a way that Yudkowsky would _have_ to understand even if Scott didn't. But after consultation with the posse, I concluded that further email prosecution was not useful at this time; the philosophy argument would work better as a public _Less Wrong_ post. So my revised Category War to-do list was:
