Nope, YOU are simply wrong, because you don't understand how big logic
actualy is, because, it seems, your mind is to small.

But logic systems don't necessaily deal with "expressions of language"
in the sense you seem to be thinking of it.

Unless it just is true because it is a truthmaker by definition.
