Man is a mode of being which accommodates that dimension always open, never finally delimited, yet constantly traversed which extends from a part of himself not reﬂected in a cogito to the act of thought by which he apprehends that part; and which, in the inverse direction, extends from that pure apprehension to the empirical clutter, the chaotic accumulation of contents, the weight of experiences constantly eluding themselves, the whole silent horizon of what is posited in the sandy stretches of non thought.
