Yes, I know Don DeLillo and Thomas Pynchon are writers, but as we've been talking about the visual arts on this thread, I wasn't clear about why you mentioned them within the context of what I was asking. I wondered if they might have written about the subject, though I'm only familiar with them as novelists.
I mentioned Dada is because you mentioned it in your post. What do you mean by: "Dada sort of symbolizes postmodernism in art" ?
That doesn't make sense.
The reason I mentioned feeling confused by the term
postmodernism is because I've come across a number of different definitions of it in my reading, like the one I mentioned earlier.
Another I came across just recently: "A late 20th Century style & conceptual theory in the arts and architecture characterized by a general distrust of ideology as well a rather difficult relationship with what constitutes art".
I don't particularly want to go on and on about this, I just asked if anyone could explain it in simpler terms, that's all.
