Either the Chinese Room uses an integrated, syntactic-semantic component to produce fluent Chinese speaking behaviour.
In which case, the room is not purely syntactic, as Searle claims it is.
Or the room works purely on the syntactic rules.
In which case, it won't produce fluent Chinese speaking behaviour, because fluency requires the ability to extrapolate beyond specified syntactic rules (like those contained in the rulebook).
In either case, the room is not as Searle describes it.
Patricia Hannah, 1985
