Abstract
Poised on the cusp between phenomenology and materiality, media institute a theoretical oscillation that promises to displace the empirical-transcendental divide that has structured western meditation on thinking, including the thinking of technics. Because media give the infrastructure conditioning thought without ceasing to be empirical, they form the basis for a complex hermeneutics that cannot avoid the task of accounting for its unthematizable infrastructural condition. Tracing the oscillation constitutive of such a hermeneutics as it serves variously to constitute media theory in the work of critics from McLuhan to Kittler, from Leroi-Gourhan to Stiegler, my interrogation ultimately conceptualizes the medium as an environment for life:by giving concrete form to ‘epiphylogenesis’, concrete media find their most ‘originary’ function not as artifacts but via their participation in human technogenesis.
