@Vamp898@social.tchncs.de Actually thats exactly what they did. It was a **fact** in 2000 that pluto was a planet.. then in 2003 I think it was a bunch of people got together and decided to change around some historically accepted vocabulary to something new. So now in 2019 according to any linguistic system which accepts the new modified definition, it is **now** a fact that it is not a planet.

But since it was little more than a linguistic revision, and has nothing to do with any fact intrinsic to the material world, it is only true within the linguistic model they created.

So thats a very weak argument for pluto being a planet in my eyes.As you said facts cant be voted on, yet that is exactly what happened with pluto, you contradicted yourself.
