But it is a little allegory all on its own of the logic of the parasite. The workings of communication are themselves no more than a sort of bridge-work, made for the spanning of a gap, or traversal of a distance. But the absent-mindedly misplaced spanner within the works is enough to make it grind, scrape, clank, eventually seize up altogether. Something alien, something stubborn and slow, has intervened in the angelic passage of messages. …
…Interference comes about not just because the apparatus of communication is too dull to convey the subtleties of our thought and voice, but also because it is too sensitive, too easily inflected by the medium through which it should travel indifferent.
