Tim Parks, Writing for the New York Review of Books, thinking through the fate of complexity and how writing will adjust over time to readers’ dwindling spans of attention:
What I’m talking about is the state of constant distraction we live in and how that affects the very special energies required for tackling a substantial work of fiction—for immersing oneself in it and then coming back and back to it on numerous occasions over what could be days, weeks, or months, each time picking up the threads of the story or stories, the patterning of internal reference, the positioning of the work within the context of other novels and indeed the larger world.
From the conclusion:
I will go out on a limb with a prediction: the novel of elegant, highly distinct prose, of conceptual delicacy and syntactical complexity, will tend to divide itself up into shorter and shorter sections, offering more frequent pauses where we can take time out.
Similar ideas being thought about here, on reading and “the attention war.”
