The article refers to the interpretation of Edmund Husserl's genetic phenomenology by Ludwig Landgrebe. Although there is no appearing that is not an appearing for an I for Husserl, the event of appearing always has a subjective character in which embodiment participates to a significant extent.
So for Landgrebe embodiment is not the origin of the subjective character of the event of appearing, but it is certainly a specific condition for this event, which accordingly allows him to say that transcendental subjectivity has a bodily character.
