This article is based on Gibson’s “experimental phenomenology” and ecological perspec- tive. It aims to develop Merleau-Ponty’s concept of “incarnate” by relating it to the more general concept of “illusion” in order to apply it to digital environments and immersive virtual realities. First of all, we should clarify, from a phenomenological point of view, the notion of “world.” Although the concept of “world” is closely linked to that of “reality,” it cannot be superimposed on it. We will analyze this distinction by focusing on specific cases of optical-geometric illusions and their ontological and epistemological implications. We will then extend them from the natural to the digital world.
