It is this configuration that, from the nineteenth century onward, changes entirely; the theory of representation disappears as the universal foundation of all possible orders; language as the spontaneous tabula, the primary grid of things, as an indispensable link between representation and things, is eclipsed in its turn; a profound historicity penetrates into the heart of things, isolates and defines them in their own coherence, imposes upon them the forms of order implied by the continuity of time; the analysis of exchange and money gives way to the study of production, that of the organism takes precedence over the search for taxonomic characteristics, and, above all, language loses its privileged position and becomes, in its turn, a historical form coherent with the density of its own past.
