The theme

The theme of " the fall of the house of usher"

The fall of the house of usher is a  great story. The fall of usher can have so many themes. It can have a theme of madness ,fear, and isolation.  The madness drives character Rodrick to his illness and believes the family is hunted by this house in a supernatural way. The fear seems to play a key factor in this story. Rodrick seems to fear "fear" itself. Could fear be the responsible for  some deaths in this story?  As for isolation, the Usher family isolates themselves . They have excluded themselves from the outside world.  Their isolation  has made them develop their own reality that would be strange to an outsider.
