 We turn now to relational ontologies. Constituent ontologies, recall, have it that objects have properties as parts or constituents. Relational ontologies accept that the extension of both object and property is not  empty[30]—but  for them, no object has any property as a part or constituent. Objects are, one might say with Armstrong, blobs (1989: 76–77). Most relational ontologists will be perfectly happy to say that objects have parts—it’s just that none of those parts are properties; they’re other objects.
