Experience is relational before it is intentional; it doesn't arise for a subject but into presence, as if the boundless screen on which it falls is itself aware but without  centre. For anything to appear there must be this complement which does not appear, but from which every feature of appearance is drawn. But to say it this way confuses the kind of being that belongs to the site of appearance with the kind of being that belongs to appearances. There is no way in thought to get to this.
