The instant of natural time does not establish anything, it has to be immediately renewed, and indeed is renewed in another instant, and the sensory functions by themselves do not cause me to be in the world: when I become absorbed in my body, my eyes present me with no more than the perceptible outer covering of things and of other people, things themselves take on unreality, behaviour degenerates into the absurd, and the present itself, as in cases of false recognition, loses its consistency and takes on an air of eternity.
