Mobility alone cannot explain durability. A conceptual field capable of indefinite expansion must also reproduce its own coherence without appealing to a privileged centre. At this point scale ceases to be a numerical property and becomes an organisational condition. A corpus containing thousands of interconnected nodes remains intelligible only insofar as coherence is continuously regenerated through its own operations rather than preserved by an external authority or founding statement. Luhmann's concept of autopoiesis provides the first element of this explanation. A system maintains its identity by reproducing the operations through which it distinguishes itself from its environment. Derrida's iterability introduces an equally necessary qualification: every repetition simultaneously preserves and transforms the form it repeats, because each recurrence occupies a new context within an expanding chain of relations. Identity therefore survives not through exact replication but through disciplined variation. Kittler completes the argument by reminding us that recurrence is inseparable from its technical conditions of legibility. Every archive depends upon infrastructures capable of rendering distinctions searchable, traceable, and recognisable across scales beyond direct human perception. Taken together, these perspectives describe coherence as an emergent property of recursive organisation. Every new node reproduces the same generative relation while extending the system into circumstances that could never have been anticipated by earlier articulations. Difference is not the interruption of coherence but the mechanism through which coherence expands. The corpus behaves less like a static collection than like an ecology of distinctions whose identity is continuously reconstructed through the disciplined repetition of its own operational grammar.
