So what we are describing with these "facts" is not the world in itself but how we've chosen to construct it in communities of meaning. It could be otherwise.
The description of the world is not the world, like a picture of me is not me.
This is a funny semiotic game who made at this time the happyness of Magritte.
But where do we go concretely and pragmatically by saying that, yes, things are how they are, but with another scheme, in another paradigm, they would have been different ? It's stating the obvious!
But why not ? Anyway changing of paradigm to explain and understand the reality don't have any influence of the reality. The earth will still have the same form, independantly of the naming of this form!
