I was intrigued to hear that Chomsky was explicitly straying into
sociolinguistic territory.  I scanned "Deterring Democracy" for similar
explicit linguistic (as opposed to political) analysis for a (only
half-sarcastic) quote for a review of an anthropological linguistics
conference. Chomsky in that book from my cursory reading only analyzed
language in a very general way. Can anyone suggest similar quotes from any
other of his books where he might comment on language in the way that
Celso's quote suggests?
