I consider in this article Heidegger’s late characterization of phenomenology as a “phenomenology of the inapparent.” Phenomenology is traditionally considered to be a thought of presence, assigned to a phenomenon that is identified with the present being, or with an object for consciousness. The phenomenon would be synonymous with presence itself, with what manifests itself in a presence. However, I will suggest in the following pages that phenomenology is haunted by the presence of a certain unappearing dimension, a claim that was made by Heidegger in his last seminar in 1973, when he characterized the most proper sense of phenomenology as a “phenomenology of the inapparent.” I attempt to show in what sense for Heidegger the “inapparent” plays in phenomenality and in phenomenology, and to then consider (drawing from Levinas and Derrida) its ethical import.
