Nabokov on poshlost'. (I won't link to the dim undergrad paper on him still lurking around these parts.) How about this instead for exhibit A, proof that Nabokov was right about some things: Ken Starr busy praising Dostoevsky's "character" and "worldview" in the infinitely tired drones of the Christian commencement speaker.
Addendum: Exhibit B would have to come from here, that Nabokov's lyricism is itself murderous, i.e. is not there just for show...is in fact a crucial part of the show.
