However, it remains a question of drawing together a maximum of disparate series (ultimately, all the divergent series constitutive of the cosmos) by bringing into operation linguistic dark precursors (here, esoteric words, portmanteau words) which rely upon no prior identity, which are above all not 'identifiable' in principle, but which induce a maximum of resemblance and identity into the system as a whole, as though this were the result of the process of differenciation of difference in itself (see the cosmic letter in Finnegans Wake).
