--from Lectures on Literature
It's somehow fitting that with this endless eyesore of a sentence, Nabokov exactly imitates the unreadable style of James Joyce.
Perhaps he's being deliberately ironic and making some kind of lit-crit joke. Maybe this is the kind of prose that makes literature grad students nod knowingly and LOL to each other.
Then again, maybe it's just terrible writing. Arrogant, terrible writing.
Have mercy on your readers. Don't choke them to death. Break your sentences down into chewable pieces and help your readers understand what the hell you're saying.
