Put it in the freezer?

One important element of Saussure’s conception of language is its social aspect (9). Language, as opposed to speech, “is not a function of the speaker. It is the product passively registered by the individual. It never requires premeditation, and reflexion enters into it only for the activity of classifying it” (14). He instills language with its own agency, in the sense that it changes and evolves, seemingly of its own accord, since it is under the control of a group rather than the individual. However, he also makes the point that “A language has connections with institutions of every sort.” This seems to tie into Benedict Anderson’s ideas about imagined communities, particularly in when Saussure discusses literary language. However, how does Saussure reconcile this idea of literary language developing through “artifical forms” and not being spoken in a way that allows “organic development” with his idea that a social aspect and evolution are unavoidable in language? He certainly poses the question, but does he decide that these efforts result in the death of the language? I think this is suggested by his writing, “Eventually every literary language, as a product of culture, becomes cut off from the spoken word, which is a language’s natural sphere of existence” (22). I guess my questions is this: is there some other (unnatural? isolated?) sphere in which language can exist?
