Siegert relocates media theory from identifiable media objects to operative chains that precede and generate distinctions such as human/nonhuman, inside/outside, signal/noise and nature/culture. Cultural techniques are therefore neither instruments added to an already constituted world nor symbolic representations of it; they are recursive practices through which ontological differences become materially executable. Writing, counting, drawing, measuring, filtering, opening and closing acquire theoretical force because they articulate the real before stable concepts retrospectively name their effects. Methodologically, Siegert replaces the search for hidden meaning with historical reconstruction of inconspicuous operations, technical supports and procedural sequences. His emphasis on grids, doors, registers, diagrams and inscription technologies turns media archaeology into an analysis of how realities are formatted. The wider bridge is especially precise toward posthumanism, Actor-Network Theory and the history of science: agency resides in heterogeneous networks of objects, gestures and procedures, while ontology itself is displaced into historically contingent operations that repeatedly produce and revise cultural distinctions.
