What are the symbols of the conflict between good and evil in the novel?I have the houses already of course but what else is there?
Wuthering Heights is full of dualities in themes, settings, characters, and symbols. As the other editor has said, I would classify the symbols are "wild" vs. "civilized" rather than "good" vs. "evil":
- Man is civilized, the devil is wild. “Is Mr. Heathcliff a man? If so, is he mad? And if not, is he a devil?”
- Edgar's affection for Catherine is civilized, but Heathcliff's love for her is wild
- The ghost of Catherine in Part I is considered good, or at least harmless, while Heathcliff in Part II is considered evil: ("like the devil").
- The moors are considered wild, while the estates are considered civilized.
- The exposed Wuthering Heights high on the moors is considered "good" by Romantic sensibilities, while the sheltered calm of Thrushcross Grange is considered, be default, as "bad"
- There is much animal imagery that suggests wildness--which is usually bad: "rabid dog"
- Weather is usually wild: violent storms
- Doors and windows can be both: a closed door or window shows wildness, but an open one shows peace.
- Love is good, while revenge is evil.
- Death is considered wild, while life in the Linton house is considered civilized
I really don't think that Wuthering Heights is about the struggle between good and evil.
Although Heathcliff is pretty darn nasty, it's hard to see him as evil incarnate; he's more a case of a person overcome by obsessive love and jealousy.
Catherine (the elder) is certainly no saint with her two-timing of Heathcliff and Linton. Edgar Linton is a decent fellow, but a whiner, at least in his youth. Catherine (the daughter) is at times deliberately cruel to Hareton. Her cousin, Linton Heathcliff, is a pathetic crybaby who is an accomplice to Heathcliff's plot to kidnap Catherine and Nelly.
The only character whom I truly admire is Nelly. She is caring, loyal, and intelligent.
I suppose you can look at Wuthering Heights as a symbol of evil and Thrushcross Grange as a symbol of good. I, however, would prefer to see them as symbols of decay and civilization, respectively.
