"To speak of there being something/nothing out there is meaningless to me unless I can see why to care."

Do you cross the road with your eyes shut? If not, you are assuming, like everyone else, that there are things out there which are terminally disutiilitous.

Note the bold.

Whose language ? What language?

English, and all the rest that I know of.

If you think all language is a problem, what do you intend to replace it with?

Something better would be nice, but what of it? I am simply saying that language obscures what is going on. You may or may not find that insight useful.

It refers to the stuff that doesn't go away when you stop believing in it.

If so, I suggest "permanent" as a clearer word choice.
