Abstraction is not cooperative, Stokhof and Lambalgen

In a study, online, on idealisations, we read:

"A last example concerns semantics and pragmatics as branches of
linguistic theory, and the central role played by the concept of `propositional
content'. The dominant paradigm here relies on a principled
distinction between propositional content as semantic meaning, and
the use of expressions with such contents that results in pragmatic
meaning. With the distinction comes a hierarchical relation: propositional
content is independent from pragmatic meaning, whereas the
latter needs the former as the base from which it is derived. This
is the Gricean model and certainly within linguistics it is still the
most used one.

Of course there are di erent views on what exactly the propositional content
of an expression is, on how it is to be determined, and, consequently, where
exactly the dividing line between semantics and pragmatics is to be drawn. But
those discussions still operate within the assumption that the distinction, and
the hierarchical relation between the two concepts of meaning, make sense.

In the philosophical literature the distinction as
such has been subject of some debate.

However, what is relevant
to note here is that `radical contextualism', the view that rejects
the distinction, does not seem compatible with the goals of modern
linguistics. And that indicates that the concept of propositional
meaning as such is yet another example of a construction that is not
so much an abstraction as an idealisation."
