" Visible and mobile, my body is a thing among things; it is one of them. It is caught in the fabric of the world, and its cohesion is that of a thing. But because it sees and moves itself, it holds things in a circle around itself. Things are an annex or prolongation of my body; they are incrusted in its flesh, they are part of its full definition; the world is made of the very stuff of the body. These reversals, these antinomies, are different ways of saying that vision is caught or is made in the middle of things, where something visible undertakes to see, becomes visible for itself and through the vision of all things, where the indivision of the sensing and the sensed persists, like the original fluid within the crystal. "

― Maurice Merleau-Ponty , L'Œil et l'Esprit
