Life is motion, and motion is concerned with what makes man move—which is ambition, power, pleasure. What time a man can devote to morality, he must take by force from the motion of which he is a part. He is compelled to make choices between good and evil sooner or later, because moral conscience demands that from him in order that he can live with himself tomorrow. His moral conscience is the curse he had to accept from the gods in order to gain from them the right to dream.
— William Faulkner, "The Art of Fiction No. 12"
