Abstract : Literature is a stream from which gush forth the inexhausting flows of paradoxes; we have immersed ourselves in this entertwining of dichotomies to perceive the underlying unity behind the oxymoron constituting the title of our thesis: "a poetics of the abjection in American postmodern gothic literature." If we have chosen Stephen King, Peter Straub and Chuck Palahniuk and have focused on three specific novels, our demonstration intends to be transposed to the whole range of their works. We wondered about the nature of abjection and its pre-eminence in an American society bearing the seal of Puritanism. Marked by Romanticism and the English gothic, our authors have been able to convey to the themes characterizing those movements a new direction. Setting our novels in the wake of postmodern gothic is a way for us to oscillate on the paradigm of excess and incompleteness, deconstruction and unity. The theme of fragmentation appears as one of Ariadne's clues allowing the authors to weave their gossamery web around the readers. This dismantling which both affects the narrative and thematic dimension of the novels contributes to the patchwork and subversive effect engendered, linking us to our postmodern problematic. The paradoxes engendered by our novels give them their strength and account for their fascination on the audience. Our peregrinations leading to the opening of the various interpretative doors reveal that abjection becomes the source of a new aesthetics. Ugliness can convey beauty and sublime. The harmony which exists in the world of discrepancy depicted to us explains the hypnotic ascendancy of the literature of abjection on the reader. Source of poetry, it brings about a pleasure of reading verging on climax for those who let themselves be carried away by the creative magic of our authors.
