I shouldn’t have been quite so dismissive of the linguistic work that has gone on in the last 50 years; of course there are people out there doing work on new languages, particularly the ones that are dying out every week here in America. The problem is, they’re so few, and they’re fighting against the ruling paradigm in academic linguistics, so they get very little encouragement or academic reward for their good work.
Chomsky and his followers are extremely contemptuous of the previous school called “Structural Linguistics,” whose contribution was to stop trying to fit all the world’s extremely diverse languages into the Procrustean bed of Latin Grammar, and analyze each one in its own terms. Many languages, particularly American languages, seemed so bizzare in their structure compared with Indo-European that the feeling developed that languages could vary almost indefinitely.
This is the attitude that modern linguistics laughs to scorn. Their theory is that all languages are at root the same, controlled by the same “linguistic organ” in the human brain, and it is the business of linguistics to map that organ, not to study all the ephemeral “surface structure” displayed by real languages. Also, Chomsky himself is quite dismissive of mere “polyglots” who go out and learn different languages; a truly intelligent person such as…well…himself, “finds learning all those words much too boring.” And since all languages are really the same, you can learn all you need to by analyzing your own language ever more deeply.
The stultifying effect this has had on Comparative Linguistics is bad enough, but the tragedy is, there are languages whose last speakers are dying somewhere in the world every year without ever being described adequately, and so when interest revives again in studying the incredible diversity that human language displays, a lot of material for that study will be forever unavailable.
Also, those few who still try to discover the affiliations of languages, in the fear of being labeled “mere speculaters,” have become extremely conservative; requiring any suggestion of a relationship between families be accompanied by a thoroughly worked out grammar of the proto-language ancestral to both. If Sir William Jones had been held to such a standard in 1794, the Indo-European family would be regarded as nothing but a childish speculation, as Greenberg’s Amerindian or Shtaroshtin’s Nostratic Superfamilies are today. That’s not to say that every suggestion of larger groupings is correct, but the majority of academic Linguists these days won’t even look at the evidence.
Sorry to be so long-winded, but I feel very strongly on this subject! Have a nice day, all!
