The method of phenomenology makes possible, as we have seen, an analysis of what is present to consciousness by revealing the structure of consciousness in its various spheres of operation. The work of the-matization presupposes existing entities, a world; it presupposes "consciousness of" the relation with an object, with what is posited. Levinas does not question the methodological adequacy of phenomenology, its power to uncover the structure of cognition, the relation of consciousness to all positing. But at the heart of Levinas' thought is the question: does thematizing consciousness exhaust the data of all experiencing?
