In Armstrong's view, nominalisms can also be criticised for producing a blob theory of reality. Objects have structure: they have parts, those parts are made of molecules, which are in turn made up of atoms standing in relation to one another, which are in turn made up of subatomic particles and so on. Blobbiness also threatens Platonic universals: a particular instantiating a universal in a world of Platonic universals becomes a matter of the blob-particular having a relation to a universal "elsewhere" (in the Platonic heaven, say), rather than having an internal relation in the way that a chemical element does to a constituent atom.
