Dear Bill,

Thanks for your further comments.

Yes, it's quite possible that some general properties of languages are due
to the "underlying mental structure/archirecture" (=cognitive constraints,
or what I've called the "cognitive code"), while others are due to
functional constraints.

The question is: How do we tell whether a general property is due to one or
the other factor? It seems to me that if we find a functional motivation for
a generalization (e.g. in terms of frequency of use; thus, since Croft
(1991) we have known that systematic noun-verb-adjective distinctions in
languages are due to different usage frequencies of thing, action and
property words in reference, predication and modification functions), then
we have no evidence that a mental/cognitive constraint is involved.

The problem with the generative approach is that it tends to jump to a
conclusion about the mental architecture without considering simpler
functional explanations. (It's as if one tried to infer the genetic code
from the phenotype of organisms, without taking adaptation into account.)

Maybe, but how do we know? Most proposals about the mental architecture
(=UG) are based on typology (i.e. existing languages), but if existing
languages are a tiny subset of cognitively possible languages (just as
existing organisms are a tiny subset of genetically possible organisms),
then this evidence is quite useless for that goal. ("Typology is irrelevant
to grammatical theory", as Newmeyer put it: cf. his 2005 book "Possible and
probable languages".)

I don't know whether there is a "specifically linguistic modality", and I
don't know about possible cognitive constraints on language structure. As I
said earlier, I think experiments with artificial languages are perhaps the
best way of finding out about them (just as biologists first learned about
genetics from "artificial organisms", i.e. breeding experiments). So far we
seem to know very little, and it's best to be agnostic, rather than take a
particular view from the outset.

Thus, typology should not try to be like genetics, but like comparative
zoology and botany: Go out to the field (documentation), collect specimens
for museums (description and creation of typological databases such as
WALS), and build a theory of adaptation that accounts for the general
patterns that are found.

Best,
Martin
