The fringe of indetermination which surrounds individuals and the relative, floating and fluid character of individuality itself has often been commented upon…The error, however, is to believe that this indetermination or this relativity indicates something incomplete in individuality or something interrupted in individuation. On the contrary, they express the full, positive power of the individual as such, and the manner in which it is distinguished in nature from both an I and a self. …Indeterminate, floating, fluid, communicative and enveloping-enveloped are so many positive characteristics affirmed by the individual. It is therefore insufficient to multiply selves or to ‘attenuate’ the I in order to discover the true status of individuation. We have seen to what extent selves must be presupposed as a condition of passive organic syntheses, already playing the role of mute witnesses. However, the synthesis of time which is carried out in them refers precisely to other syntheses as though to other witnesses, thereby leading us into the domain of another nature in which there is no longer either self or I, and in which, by contrast, we encounter the chaotic realm of individuation.
