Abstract
Sartre’s Critique of Dialectical Reason depends upon an ideal of subjectivity that operates linguistically. The subject of the Critique progresses through three transformations: first, the organic subject; second, the serial subject; third, the common subject. Each stage reveals different configurations of the expressive possibilities inherent in Sartre’s late conception of subjectivity and his materialistic view of language. The organic subject emerges in the initial contradiction between the human organism and its material environment. This contradiction results in the primordial movement of signification that projects a future structured in response to the material system. The serial subject then emerges within the system of language and a social structure of antagonistic struggle. Finally, the common subject emerges out of the dissolution of the serial subject by means of a repetition of the original expressive gesture. This common subjectivity is the site of a complete communication occurring within the group-in-fusion.
