 A distinct but related case against the folk ontology is that the delineation of a population as speakers of a single language is invariably driven by geo-political considerations. Serbo-Croatian and the Czechoslovak languages endured only as long as nationalist politics required them to, and ceased to be almost overnight, without any major change in how people spoke. Some dialects of the Netherlands are closer in their characteristics to dialects in neighboring Germany than they are to dialects spoken on the Netherlands coast, despite being grouped with the latter but not the former as variants of the same language, Dutch. The concern here is not well captured in the observation that languages in the folk sense are fuzzy. The special sciences are replete with fuzziness. Rather, the individuation conditions seem arbitrary from a linguistic perspective. The same arguments against languages in the folk sense apply at the level of dialects in the folk sense. Cockneys, and hence speakers of the cockney dialect, are traditionally required to have been born within earshot of the bells of Bow Church in east London, but noise pollution and demographic change have rendered that definition absurd. No matter how fine-grained a version of the folk ontology one seeks out, similar problems will recur.
