An obvious thing

 A very obvious thing, but Cortázar in a long, long interview talks about the fact that literary writing is not "higher" than other forms of writing, in register, but more exact, stylistically fine-tuned, so that Roberto Arlt's tales of street life in Buenos Aires are written in the exact language they require, being colloquial in this particular instance, but different depending on each writer and the particular world vision. So Cortázar himself does not want to publish anything that isn't exactly right. 

I was thinking of this yesterday, in relation to a Bob Dylan song. It is exactly the language that we would have used in real life in the 1970s or 1960s, like "It's such a drag."
