This article contends how Toni Morrison has used her black fiction to reject the dominant conceptions of reality and truth constructed by the white pahllogocentric discourses that tended to perpetuate white power interests. The poststructuralist assumption that knowledge and reality are socially constructed phenomenon provides useful insight into Morrison's narrative strategies and helps understand how, on one hand, she represents the ways the history of the black Africans had been badly disfigured in the white discourse resulting in the construction of the negative stereotypes of the black people as barbarians, savages, and uncivilized people whose mythical history and social values were invalidated as inauthentic and savage that needed the enlightening intervention of the white Europeans and, on the other hand, apart from revealing the discursive facts that control reality formation, she disrupts and displaces dominant and oppressive white knowledges.
