“It [writing] has enormous meta-cognitive implications. The power is this: That you cannot only think in ways that you could not possibly think if you did not have the written word, but you can now think about the thinking that you do with the written word. There is danger in this, and the danger is that the enormous expressive and self-referential capacities of the written word, that is, the capacities to keep referring to referring to referring, will reach a point where you lose contact with the real world. And this, believe me, is very common in universities. There's a technical name for it, I don't know if we can use it on television, it's called "bullshit." But this is very common in academic life, where people just get a form of self-referentiality of the language, where the language is talking about the language, which is talking about the language, and in the end, it's hot air. That's another name for the same phenomenon.”
