This is what PG states:
> It's too much to hope that writing could ever be pure ideas. You might not even want it to be. But for most writers, most of the time, that's the goal to aim for. The gap between most writing and pure ideas is not filled with poetry.
I think that's virtually meaningless unless you define what is meant by "an idea". The Bible, Qu'ran, the story of Gilgamesh, Homer's Illias,... are all ideas, just the same as famous essays by Hemingway or Benjamin Franklin. Even Proust's In Search of Lost Time with it's epic long sentences is a multitude of ideas regarding involuntary memory, separation anxiety and much more.
Everything PG writes after that hinges on a single imperative: That if you intend for your writing to be read, you must write simple.
The trouble is that his argument doesn't challenge that. There's no reflection on the fact that this is by far an universal principle, or that it, paradoxically, defines the relationship with the reader as if the latter always wants simple, digestible reading at every turn.
Hemingway is famous for his terse and simple writing, attributed to his schooling as a journalist. But he also had a critics who simply despised his literary writing for its terse and uncompromising style. And then there's William Faulkner who had this baroque style with long, endless sentences which dug their heels into Big Emotions, trying to convey them in the most sinuous way possible. Faulkner, just like Hemingway having won the Nobel Prize, found himself the butt of criticism on his writing as well.
Sure, these musings pertain to great literators. PG's point could be relegated to articles and essays instead. Or, unspoken yet more to the point, writing as this ephemeral, intangible idea that disolves and dissappear like vapor clouds the second it is published in the digital realm. Unlike words which are printed in respectable paper journals and glossy magazines.
No, the writing style of PG's essay was also part of this expose. Leveraged by the author to drive a point home. I'm still not sure what that point was exactly. PG being PG, chances are he just wanted nothing more then to make a so-called thought-provoking statement. In that regard, simple writing doesn't automatically make for good writing. The idea, the essence, you're trying to sell still needs to be solid and worth telling. That's where PG's essay, ironically, falls flat.
PG's essay doesn't spark a debate because he writes about an idea, it sparks discussion because of quite the opposite: writing about anything except about writing or why one writes. Now, one can fault PG for not providing context, but as with anything in this digital world, PG publishes on his own websites and assumes that the reader had written his other writings as well to understand what he's trying to get at. That's fine. It just doesn't make for compelling reading if one has to pieces together.
