Edgar Allan Poe's stories often reflect some of his own personal problems. William Wilson and The Cask of Amontillado are usually classified with the label tales of the double (or evil) personality. They reflect one of the strangest aspects of Poe's life. He actually had a blurred identity, and his quest to find who he was is visible in the different names he assumed during his early life: born Edgar Poe, he was an orphan at the age of three and was adopted by the Allans. This is whence his middle name came: he took it when he was fifteen years old. Three years later his adoptive father pushed him to enlist in the army, where he wanted to be called Edgar Perry. Poe is also known to have been a heavy drinker and a drug addict, but at the same time he was aware of these vices and tied to fight against them; this is another aspect of his blurred personality.

[...] The facts that the ‘Other' looked exactly like Wilson and behaved in the exact same way as he does, that he only whispered, that no one else seemed to notice him and that he appeared only in moments when Wilson's imagination was stimulated in some way, prove that he had no other existence than in Wilson's very mind. He admits that is] the descendant of a race whose imaginative and easily excitable temperament has at all times rendered them remarkable' (par. [...]
[...] Yet Wilson refused to see himself in this image, he kept thinking it was the ‘Other', while noticing the perfect resemblance between the two of them, and between their voices, when finally the ‘Other' told him that they were both parts of the same person, and that Wilson killed himself: henceforward art thou also dead–dead to the World, to Heaven and to Hope! In me didst thou exist–and, in my death, see by this image, which is thine own, how utterly thou hast murdered thyself.' This scene confronts the reader to a problem: if Wilson killed himself, how can he write his own story? [...]
