Wallace introduces the meme of total noise:
I’m not really even all that confident or concerned about the differences between nonfiction and fiction, with ‘differences’ here meaning formal or definitive, and ‘I’ referring to me as a reader. There are, as it happens, intergenre differences that I know and care about as a writer, though these differences are hard to talk about in a way that someone who doesn’t try to write both fiction and nonfiction will understand. I’m worried that they’ll sound cheesy and melodramatic. Although maybe they won’t. Maybe, given the ambient volume of your own life’s noise, the main difference will make sense to you. Writing-wise, fiction is scarier, but nonfiction is harder — because nonfiction’s based in reality, and today’s felt reality is overwhelmingly, circuit-blowingly huge and complex. Whereas fiction comes out of nothing. Actually, so wait: the truth is that both genres are scary; both feel like they’re executed on tightropes, over abysses — it’s the abysses that are different. Fiction’s abyss is silence, nada. Whereas nonfiction’s abyss is Total Noise, the seething static of every particular thing and experience, and one’s total freedom of infinite choice about what to choose to attend to and represent and connect, and how, and why, etc.
