Individuation

"The individuating factors or the implicated factors of individuation therefore have neither the form of the I nor the matter of the Self. This is because the I is inseperable form a form of identity, while the Self is indistinguishable from a matter constituted by a continuity of resemblances. ... By contrast, every individuating factor is already difference and difference of difference. It is constructed upon a fundemental disparity, and functions on the edges of that disparity as such. That is why these factors endlessly communicate with one another across fields of individuation, becoming enveloped in one another in a demesne which disrupts the matter of the Self as well as the form of the I. Individuation is mobile, strangely supple, fortitious and endowed with fringes and margins; all because the intensities which contribute to it communicate with each other, envelop other intensities and are in turn enveloped. The individual is far from indivisible, never ceasing to divide and change its nature. It is not a Self with regard to what it expresses, for it expresses Ideas in the form of internal multiplicities, made up of differential relations and distinctive points or pre-individual singularities."
