The possibility of victory must be there in tragedy. Where pathos rules, where pathos is finally derived, a character has fought a battle he could not possibly have won. The pathetic is achieved when the protagonist is, by virtue of his witlessness, his insensitivity, or the very air he gives off, incapable of grappling with a much superior force. Pathos truly is the mode for the pessimist. But tragedy requires a nicer balance between what is possible and what is impossible. And it is curious, although edifying, that the plays we revere, century after century, are the tragedies. In them, and in them alone, lies the belief — optimistic, if you will, in the perfectibility of man.
