But as Van casually directed the searchlight of backthought into that maze of the past where the mirror-lined narrow paths not only took different turns, but used different levels (as a mule-drawn cart passes under the arch of a viaduct along which a motor skims by), he found himself tackling, in still vague and idle fashion, the science that was to obsess his mature years - problems of space and time, space versus time, time-twisted space, space as time, time as space - and space breaking away from time, in the final tragic triumph of human cogitation: I am because I die.
Vladimir NabokovYou have to be an artist and a madman, a creature of infinite melancholy, with a bubble of hot poison in your loins and a super-voluptuous flame permanently aglow in your subtle spine (oh, how you have to cringe and hide!), in order to discern at once, by ineffable signsโthe slightly feline outline of a cheekbone, the slenderness of a downy limbs, and other indices which despair and shame and tears of tenderness forbid me to tabulateโthe little deadly demon among the wholesome children; she stands unrecognized by them and unconscious herself of her fantastic power.
