I seriously doubt that anyone will successfully respond to that

That is like asking for a single axiom that relates a verb to
its object.  The approach many linguists recommend is to treat
the relation between verb and object as a syntactic mechanism
that can express a variety of "thematic roles", such as
Theme, Patient, or Result -- any of which may be subdivided
further for various special cases.    (04)

That approach makes it possible to specify different axioms for
each type of relation.  As I said before, my proposal for handling
contexts is to do something similar:  separate the syntax from
the semantics.  Then specify different axioms for each relation
type that links a proposition to a statement that says something
about that proposition.    (05)
