David Graeber

It's worth thinking about language for a moment, because one thing it reveals, probably better than any other example, is that there is a basic paradox in our very idea of freedom. On the one hand, rules are by their nature constraining. Speech codes, rules of etiquette, and grammatical rules, all have the effect of limiting what we can and cannot say. It is not for nothing that we all have the pictures of the schoolmarm rapping a child across the knuckles for some grammatical error as one of our primordial images of oppression. But at the same time, if there were no shared conventions of any kind--no semantics, syntax, phonemics--we'd all just be babbling incoherently and wouldn't be able to communicate with each other at all. Obviously in such circumstances none of us would be free to do much of anything. So at some point along the way, rules-as-constraining pass over into rules-as-enabling, even if it's impossible to say exactly where. Freedom, then, really is the tension of the free play of human creativity against the rules it is constantly generating. And this is what linguists always observe. There is no language without grammar. But there is also no language in which everything, including grammar, is not constantly changing all the time. (p. 200)
