Wait are you talking about his novel "of Mice and Men"?
Edgar Allan Poe uses unique diction to create a melancholic mood in his story. By using words like “fearing” and “dark,” he creates an aesthetic that’s fitting to the Romantic era. The use of imagery plays an important role in all of poe’s tales. His vivid descriptions creates an image of the story in the reader’s head.
Sherburn describes humanity as being cowardly because of the bob-mentality he has.
