 To every single property and to every set of properties, there is a corresponding object, either an existent or a nonexistent one. Thus, there is, for instance, an object that has the property of being round as its sole property; one might call it “the object round”, or simply “round”. There is also an object that has the property of being blue as its sole property (the object blue, or blue, for short). Furthermore, there is an object that has the property of being round and the property of being blue, and no other properties (the object round and blue); and so forth.
