Social construct.

[paulpablo]

Human choice may be a social construct , even if our ability to make selections is a fact - though some people would probably call that a semantic rounding error. Language, the words we use to refer to things, are a social construct, yes. The word is not the thing, however. Everyone changing their minds about what word to use to refer to a mountain does not change the mountain, anymore than the different words for mountain in many languages change the mountain. Pluto, as you note, being called a planet or not a planet, doesn't change pluto. This is because pluto..like a mountain... is not a social construct.

But this is the same for anything you mentioned is a social construct.

Money exists as paper, its money because we agree to use it as money.

Mountains exist as mounds of earth/rocks/whatever it is a mountain is made of, they're mountains because we agreed that when the mounds of earth reach a certain height we call them mountains.

In theory if for some quirky reason there was a split decision between geologists about the difference between a hill and a mountain, there would be mounds of earth that exist which would be socially talked about as hills to one group of people and mountains to others. Yeh they would physically exist just as the paper we treat as money still exists if we all of sudden decide to not treat it as money.

Just to add a note that my description of mountains might be off but the principle remains.
