 But for the linguist interested in the syntax-semantics interface, there needs to be some explanation of how (LF2a) and (LF2b) are associated with (EX2). It could be a way in which rules can derive (LF2a) and (LF2b) from the syntactic representation of (EX2), as some semantically-inclined Essentialists would propose, or a way to explain the syntactic properties of (EX2) from facts about the meanings represented by (LF2a) and (LF2b), as some Emergentists might want. But that they should be connected up in some way is something that linguists would typically count as non-negotiable.
