When that slow-motion, silent explosion of love takes place in me, unfolding its melting fringes and overwhelming me with the sense of something much vaster, much more enduring and powerful than the accumulation of matter or energy in any imaginable cosmos, then my mind cannot but pinch itself to see if it is really awake. I have to make a rapid inventory of the universe, just as a man in a dream tries to condone the absurdity of his position by making sure he is dreaming. I have to have all space and all time participate in my emotion, in my mortal love, so that the edge of its mortality is taken off, thus helping me to fight the utter degradation, ridicule, and horror of having developed an infinity of sensation and thought within a finite existence.
Vladimir Nabokov in Speak, Memory, quoted by my heroine Abby, who rebuts a classroom critic of the author:
in class some twit complained that nabokov was uselessly pretentious and pedantic, that he used latin terms and untranslated french and russian to intentionally muddle the reader. i can agree that his writing is extravagant at times, that he creates puzzles he knows we will never master, and that occasionally he hints that our intelligence is inferior to his (which, in most cases, is undeniably true). but i argued that in his memoir the inclusion of multiple languages, the movement between the sensory and the scientific, the distortions and expansions of time are all methods of grasping onto his own mortality, a desperate attempt to hold onto ephemeral memory, and to express the self —ever bifurcated between the past and the present, that which we feel and that which we can articulate.
I consider criticism of Nabokov’s “pretentiousness” to be specious until it can be demonstrated that his artistic aims might have been achieved with plainer prose. I doubt many of his detractors even bother to consider his aims, however; they’re too busy reacting, as most readers do, to the phantom author whose personality they imagine and judge on the basis of individual, largely aesthetic and demographic preferences. Pretentiousness is a matter of purpose and intent, not merely of diction or style (although they can be clues to intent, of course); there are pretentious epigones of Hemingway and Carver, for example, whose simple sentences constitute a self-regarding affectation, a false, contrived humbleness; there are surely even pretentious illiterates.
