In "The Fall of the House of Usher," what evidence supports the quote below?When isolated from the real world, a person can be infected by another...

I really like this quote, especially as it is applied to
"The Fall of the House of Usher." It is clear that you could easily refer this quote to
the somewhat parasitic relationship that exists between Madeline and Roderick. From the
very beginning of the tale, the narrator establishes a link between them, and not just
concerning their status as twins. Both are described as half-dead human cadavers, with
their mysterious diseases having wasted their flesh away. If you look carefully at how
the narrator describes both of them, it is clear that he struggles to connect them with
any human form. Note what he says about Roderick:

I could not, even with effort, connect its
Arabesque expression with any idea of simple
humanity.

The sight of
Madeline strikes the narrator with a feeling of "utter astonishment not unmingled with
dread," which the narrator finds it impossible to account for. Clearly, the fact that
Roderick and Madeline live so far away from the real world in an isolated, gloomy house,
which again is linked to its owners by its description of rotting decay, has helped the
siblings to prey on each others fears and concerns with tragic
consequences.
