Scholars have additionally debated the nature of the character Beloved, arguing whether she is actually a ghost or a real person. Numerous reviews, assuming Beloved to be a supernatural incarnation of Sethe's daughter, have subsequently faulted "Beloved" as an unconvincing and confusing ghost story. Elizabeth B. House, however, has argued that Beloved is not a ghost, and the novel is actually a story of two probable instances of mistaken identity. Beloved is haunted by the loss of her African parents and thus comes to believe that Sethe is her mother. Sethe longs for her dead daughter and is rather easily convinced that Beloved is the child she has lost. Such an interpretation, House contends, clears up many puzzling aspects of the novel and emphasizes Morrison's concern with familial ties.
