Do you feel a duty to read and acknowledge your literary, theoretical, and musical foremothers?
I’d argue that most people have no idea who their artistic forebears are. For example: students tell me all the time that David Foster Wallace is their favorite novelist. And when I see their work, they’re indeed writing very DFW-influenced stuff. But they rarely know anything about DFW’s own inspirations, or the lineage(s) he inhabits.
This is only natural; we all of us live artistic lineages backward. (I’m no exception; my initial influences were G.I. Joe and X-Men comics.) And this is why I’ve been saying for a little while now (polemically, mind you) that Ulysses is no longer all that influential a novel: not many people sit down and actually read it, let alone get direct inspiration from it. (“I discovered stream of consciousness by reading Molly Bloom’s soliloquy, and now I use it in my work.”)
Rather, people read more contemporary authors, like DFW and DeLillo and Franzen and Pynchon (to name authors of a particular type), and they imitate them. And so they get a lot of Joycean influences, but only indirectly, and mainly through those authors. (E.g., they see DFW or Pynchon shifting narrative registers, but they don’t see how Joyce did a lot to pioneer that trope in Ulysses.)
This is always happening. People imitate Lydia Davis without reading the Symbolists. People (used to?) imitate Vonnegut without reading Céline. And so on.
