The Kingdom by the Sea

A normal man given a group photograph of school girls or Girl Scouts and asked to point out the comeliest one will not necessarily choose the nymphet among them. You 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 signs - the slightly feline outline of a cheekbone, the slenderness of a downy limb, and other indices which despair and shame and tears of tenderness forbid me to tabulate - the deadly little demon among the wholesome children; she stands
unrecognized by them and unconscious herself of her fantastic power.

Vladimir Nabokov, Lolita.
