Who knows why certain notes in music are capable of stirring the listener deeply, though the same notes slightly rearranged are impotent? … There is no satisfactory explanation of style, no infallible guide to good writing, no assurance that a person who thinks clearly will be able to write clearly, no key that unlocks the door, no inflexible rule by which the young writer may shape his course. He will often find himself steering by stars that are disturbingly in motion.
