The suffering and calamity are, moreover, exceptional. They befall a conspicuous person. They are themselves of some striking kind. They are also, as a rule, unexpected, and contrasted with previous happiness or glory. A tale, for example, of a man slowly worn to death by disease, poverty, little cares, sordid vices, petty persecutions, however piteous or dreadful it might be, would not be tragic in the Shakespearean sense.
It is the suffering of ambivalence: the murderous alternation between bitter resentment and raw-edged nerves, and blissful gratification and tenderness
The story depicts also the troubled part of the hero's life which precedes and leads up to his death; and an instantaneous death occurring by 'accident' in the midst of prosperity would not suffice for it. It is, in fact, essentially a tale of suffering and calamity conducting to death.
