 But this criterion suggests that impure sets, object-dependent properties, abstract artifacts, and the rest are not abstract. For this criterion appears to draw a line between certain pure abstract entities and everything else. The truth of simple existence statements about \(\{\textrm{Bob Dylan}\}\) or Dickens’ A Christmas Carol, which usually are considered abstract entities, does not depend solely on linguistic rules. The same goes for simple and complex existential statements with general terms such as ‘novel’, ‘legal statute’, etc.
