Intentionality in Husserl’s theory, refers to that of consciousness. When Husserl discusses the reduction to transcendental ego through phenomenological method, he considers, on the one hand, body or “I can” as a necessary intermediary; on the other hand, he holds that body is an object which needs to be reduced and to be bracketed. Heidegger transforms Husserl’s intentionality of consciousness into Dasein’s being-in-the-world. Although Heidegger’s Dasein is being-in-the-world, the authentic Dasein has no body and Being and Time has not yet completely gotten out of the realm of transcendental philosophy. By describing perception in phenomenological method, on the basis of Heidegger’s view of Dasein’s being-in-the-world, Merleau-Ponty transforms the phenomenological matter in question from intentionality of consciousness to intentionality of body, through which he realizes subject-object and ego-object integrity, and finds man’s (Dasein’s) genuine being-in-the-world.
