+> Appeal to arbitrariness - again, the notion that [word definitions are arbitrary](https://www.lesswrong.com/lw/od/37_ways_that_words_can_be_wrong/) serves as a good example (in fact I was harvesting some of these appeals from that sequence). It's not just that this is wrong, but that it serves to cut off further discourse. Generally, anything that people are motivated to argue about is not _arbitrary_. It is being controlled by invisible criteria of evaluation, it has connotations with consequences, and if _that_ isn't true either, the topic of discourse is probably not "arbitrary" but just "meaningless". No map that corresponds to an external territory can be arbitrary.

+> _Appeal to inner privacy_ - "you can't possibly know how I feel!" It's true that modern technology still encounters some slight difficulties in reading thoughts out of the brain, though work is underway as we speak. But it is rare that the exact details of how you feel are the key subject matter being disputed. Here the bony borders of the skull are being redeployed as a hard barrier to keep out further arguments.
