Tragedy, called a more exalted kind of consciousness, is so called because it makes us aware of what the character might have been. But to say or strongly imply what a man might have been requires of the author a soundly based, completely believed vision of man's great possibilities. As Aristotle said, the poet is greater than the historian because he presents not only things as they were, but foreshadows what they might have been. We forsake literature when we are content to chronicle disaster.
