Creole Exceptionalism" is defined as a set of beliefs, widespread among both linguists and nonlinguists, that Creole languages form an exceptional class on phylogenetic and0or typological grounds. It also has nonlinguistic (e.g., sociological) implications, such as the claim that Creole languages are a "handicap" for their speakers, which has undermined the role that Creoles should play in the education and socioeconomic development of monolingual Creolophones. Focusing on Caribbean Creoles, and on Haitian Creole in particular, it is argued that Creole Exceptionalism, as a sociohistorically rooted "régime of truth" (in Foucault's sense), obstructs scientific and social progress in and about Creole communities. Various types of Creole Exceptionalist beliefs are deconstructed and historicized, and their empirical, theoretical, and sociological flaws surveyed. These flaws have antecedents in early creolists' theories of Creole genesis, often explicitly couched in Eurocentric and (pre-0quasi-)Darwinian doctrines of human evolution. Despite its historical basis in colonialism and slavery and its scientific and sociological flaws, Creole Exceptionalism is still enshrined in the modern linguistics establishment and its classic literature, a not unexpected state given the social structure of scientific communities and the interaction between ideology and "paradigm-making." The present Foucauldian approach to Creole Exceptionalism is an instantiation of a well-defined area of the linguistics0ideology interface. The conclusion proposes alternatives more consistent with Creole structures and their development, and more likely to help linguists address some practical problems faced by Creole speakers.
