Describing pinker's thoughts on linguistic descriptivism:
Steven Pinker's 1994 "The Language Instinct" is a good and fairly literate example of this second kind of Descriptivist argument, which, like the Gove-et-al. version, tends to deploy a Jr.-high-filmstrip SCIENCE: POINTING THE WAY TO A BRIGHTER TOMORROW-type tone...
I think it's a lot closer to the truth to say that humans tend to be human throughout history, for both good and ill, and that this alone is why neither anyone's idea of utopia nor dystopia will ever really happen. We're always somewhere in the middle.
