The doppelganger, German for “double-goer,” is a literal or symbolic double set in opposition to one of the characters of the story. This theme has appeared in literature for centuries, but is especially popular in works of Gothic fiction. Though, in the most literal sense, a doppelganger is a fellow human being who bears a striking physical resemblance to another character, in these stories, supernatural or imagined doubles with symbolic significance, or sometimes even different aspects of the same person, can be considered doppelgangers. The idea of a doppelganger or alter ego allows for an exploration of human duality. The doppelganger is both duplicate and opposite, showing how opposing forces can exist in one being and forcing us to confront our divided selves.
