" We must accustom ourselves to understand that 'thought' is not an invisible contact of self with self, that it lives outside of this intimacy with oneself, in front of us, not in us, always eccentric. Just as we rediscover the field of the sensible world as interior-exterior, so also it is necessary to rediscover as the reality of the inter-human world and of history a surface of separation between me and the other which is also the place of our union, the unique Erfullung of his life and my life. It is to this surface of separation and of union that the existentials of my personal history proceed, it is the geometrical locus of the projections and introjections, it is the invisible hinge upon which my life and the life of the others turn to rock into one another, the inner framework of intersubjectivity. "
― Maurice Merleau-Ponty , The Visible and the Invisible
