 It is interesting to notice that a separate-realm theory of universals permits of a blob as opposed to a layer-cake view of particulars. For on this view, what is it for a thing to have a property? It is not the thing’s having some internal feature, but rather its having a relationship, the instantiation relationship, to certain universals or Forms in another realm. The thing itself could be bloblike. (Armstrong 1989: 76–77)
