This paper studies the New Novel's rhetoric (Nouveau Roman) in order to requalify, thanks to a dialectical approach, its positive definition in a negative way. Through a philosophical critique of the novelistic discourse, the aim is to highlight the theoretical power of novels which pay attention, in a rhetorical perspective, to the body thematic, the body considered as a fundamental and full component of a subjectivity determined by material and external structures. The New Novel, analyzed first as an expression of a "sensible objectivity," gives rise to a materialist and negative dialectic and has to be understood as an immanent critique of social, political, and historical structures.
