Osiatynski: As I understand, language has an innate biological basis. Its use, however, is social. What do you think of the social functions of language? Is it primarily an instrument of communication?
Chomsky: I think a very important aspect of language has to do with the establishment of social relations and interactions. Often, this is described as communication. But that is very misleading, I think. There is a narrow class of uses of language where you intend to communicate. Communication refers to an effort to get people to understand what one means. And that, certainly, is one use of language and a social use of it. But I don’t think it is the only social use of language. Nor are social uses the only uses of language. For example, language can be used to express or clarify one’s thoughts with little regard for the social context, if any.
I think the use of language is a very important means by which this species, because of its biological nature, creates a kind of social space, to place itself in interactions with other people. It doesn’t have much to do with communication in a narrow sense; that is, it doesn’t involve transmission of information. There is much information transmitted but it is not the content of what is said that is transmitted. There is undoubtedly much to learn about the social uses of language, for communication or for other purposes. But at present there is not much in the way of a theory of sociolinguistics, of social uses of languages, as far as I am aware.
