How does pathetic fallacy affect the reader?
Pathetic fallacy can make it easier for the reader to find characters' emotions because they are shown also by the environment.
" Emily Bronte’s novel “Wuthering Heights” is full of pathetic fallacies. The title itself shows the use of this device as “Wuthering Heights” means uproarious and aggressive weather that represents the nature of its residents. There are lots of instances in the novel in which the mood of nature portrays the nature of events in the narrative. For example, “Lockwood” is trapped in a “snow storm” before the nightmare scene, the “wild and windy” night at the time of Mr. Earnshaw’s death, the “violent thunderstorm” on the night Heathcliff leaves Wuthering Heights, and the stormy weather outside when “Cathy” makes a choice between “Heathcliff” and “Edgar” indicates her inner turmoil."
