text: Additionally, Poe acknowledged that the idea of a story about the irritation one feels by meeting someone with the same name, thereby ruining a feeling of uniqueness, was inspired by Washington Irving's "An Unwritten Drama of Lord Byron". At the end of Irving's tale, the main character kills his double with his sword, only to see his own face behind the mask.
  Analysis
  "William Wilson" clearly explores the theme of the double. This second self haunts the protagonist and leads him to insanity and also represents his own insanity. According to Poe biographer Arthur Hobson Quinn, the second self represents the conscience. This division of the self is reinforced by the narrator's admission that "William Wilson" is actually a pseudonym. The name itself is an interesting choice: "son" of "will". In other words, William Wilson has willed himself into being along with the double which shares that name.
  Poe wrote the story very carefully and with subtlety. Sentences are balanced, with very few adjectives, and there is little concrete imagery beyond the description of Wilson's school. Pacing is purposely set as leisurely and measured using a formal style and longer sentences. Rather than creating a poetic effect or mood, as Poe recommends in "The Philosophy of Composition", Poe is creating a tale based on rationality and logic.
