Given that you are new, I won't vote this down. The post feels a bit out of place for LessWrong. As far as I read your post you make a lot of claims by assuming them to be an obvious development of what you say.

The problem with that is that the claims aren't very clear and you don't engage with arguments against the claims you are making. Maybe because you are unaware of the relevant literature and arguments contained within it.

As far as meaning goes, it's commonly said that the terms morning star and evening star refer to the same object. And that's true even if a person just looks at the sky and doesn't know that both are venus and thus would define them very differently.

The position of realism considering that both terms refers to the same real object and that it's not everything just in the mind of person watching the stars is quite useful for many applications.

Stylistically many of the pargraphes are also too long.
