Abstract
This chapter explores the imperceptible foundation of the play of signs that takes place on the medial surface. It begins by discussing submedial space as the space of suspicion as well as the space of subjectivity, suggesting that something invisible must be hidden behind the visible in the space beneath the medial surface. It then considers the poststructuralist philosophy of flux in relation to the problem of signification and how signification determines the relationship of the archive to the “reality” outside the archive, a reality “signified” by means of archival signs. It argues that the philosophy of flux deconstructs the border between archive and profane space by emphasizing the materiality of signs, on the one hand, and by defining all ordinary things as signs, on the other. The philosophy of flux thus considers ordinary things and archival things to be interconnected via a play of differences. The media-ontological question does not concern if and how the signs on the medial surface are able to signify the submedial, hidden space.
