The skin is a variety of contingency: in it, through it, with it, the world and my body touch each other, the feeling and the felt, it defines their common edge. Contingency means common tangency: in it the world and the body intersect and caress each other. I do not wish to call the place in which I live a medium, I prefer to say that things mingle with each other and that I am no exception to that. I mix with the world which mixes with me. Skin intervenes between several things in the world and makes them mingle.
