Has anyone been exposed to verbal judo? It's an interesting approach to communicating with hostile people. It's like communication psychology.
Psychologists have their own versions, but he knows martial arts, and is not a linguist. Martial artists have a wide variety of philosophies, and often call themselves schools of philosophy, with Judo being popular in Japan, and his body language suggesting he's actually been to Japan. Aikido is the most popular in Asia, and stresses how to use arm locks and wrestling moves, but only when necessary. I've never taken martial arts myself, but I know people. Oneness Poetry is mathematical, in the public domain, and is widely written and improved upon by people around the world. If you wish to learn verbal Judo or Aikido, I recommend Oneness Poetry, which actually performs mental Judo and Aikido on whoever attempts to read or write it.
Martial artists make great police and emergency service personal, in part, because their entire philosophy tends to revolve around avoiding conflict whenever possible. What this example of verbal Judo illustrates is the extensive use of classic logic in their training. They are not linguists, and both have been taught that English only has one grammar, when it has two and, very likely, neither one knows the dictionary merely contains popular definitions. The military has its own jargon, that the business world often adopts, because its the same Three Stooges logic and cutthroat poker. These guys use the same military style approach, of avoiding conflict, by developing a rudimentary lexicon that is specific to the job. Rather than having to be linguists, they have to attempt to agree upon the specific definitions of words for the jobs they do. After mulling it over for a little while, I realized martial arts would be an excellent place to begin developing my analog linguistics. Analog logic can be 10,000x to a million times more efficient, and is what martial arts are all about, but classic logic has dominated natural languages for over two millennium. I'm developing a rudimentary analog logic that can be used to express any language, and verbal Judo can adapt it however they want for their use. Think of ordinary language as being a steam engine, it gets you from point A to B, but the trick is to make it more self-organizing and organic, which requires developing a recursive logic that supercomputers struggle with, but not me.
