Amy Brand at The MIT Press Reader:
Amy Brand: You have tended to separate your work on language from your political persona and writings. But is there a tension between arguing for the uniqueness of Homo sapiens when it comes to language, on the one hand, and decrying the human role in climate change and environmental degradation, on the other? That is, might our distance from other species be tied up in how we’ve engaged (or failed to engage) with the natural environment?
Noam Chomsky: The technical work itself is in principle quite separate from personal engagements in other areas. There are no logical connections, though there are some more subtle and historical ones that I’ve occasionally discussed (as have others) and that might be of some significance.
Homo sapiens is radically different from other species in numerous ways, too obvious to review. Possession of language is one crucial element, with many consequences. With some justice, it has often in the past been considered to be the core defining feature of modern humans, the source of human creativity, cultural enrichment, and complex social structure.
As for the “tension” you refer to, I don’t quite see it.
