"There is a circle of the touched and the touching, the touched takes hold of the touching; there is a circle of the visible and the seeing, the seeing is not without visible existence, there is even an inscription of the touching in the visible, of the seeing in the tangible - and the converse; there is finally a propagation of these exchanges to all the bodies of the same type and of the same style which I see and touch - and this by virtue of the fundamental fission or segregation of the sentient and the sensible which, laterally, makes the organs of my body communicate and founds transitivity from one body to another." - Maurice Merleau-Ponty "The Intertwining: the Chiasm" in The Visible and the Invisible: Philosophical Interrogation (1968)
