I don't find the emergentist position, as I understand it, incompatible with
generativism, it just reverses the power relationship: category vs. example.
Generativist insights about categories are still there, in the main. They are
for me, anyway.
In particular I believe that while emergence (or generalization, actually, as
opposed to generalization_s_) is the fundamental driving force of language I
also believe that driving force must be channeled and parameterized in ways
only glimpsed through some of the insights of generativism.
And Chomsky was only ever going for principles and parameters, wasn't he,
competence rather than performance?
But I seem to have stepped in on an argument which has been going on for some
time. Excuse my ignorance of the established positions, because while I
identify strongly with what I hear of emergence I really don't know yet in
depth how the perspective has developed (over the last 15 years!)
Perhaps I can ask some questions to get to the center of it. Take your
analysis of the empirical nub, for instance. Can you tell me why you want us
to undertake `text-distributional studies of variability ("emergence") vs.
Isn't that a bit like saying let's test experimentally how much of language
is performance and how much competence?
Isn't emergence (or really I feel it's better to get down to the driving
force and say generalization) a performance model?
