- Well, if I was confused before, I am more confused now.
-
- First of all, if a view (Quinean or otherwise) requires stratification
- to deal with a purely syntactical predicate, then the issue of
- reification is not the salient one. Stratification is a strategy
- for eliminating the paradoxes whether the predicates are reified or not.
-
- Second, I have no idea whether "is heterological" expresses a bona
- fide property. I care only that whether it is a meaningful predicate.
- (What would it express if not a bona fide property? A trope?)
-
- My point was that the Grelling paradox doesn't depend on any
- quantification over properties, nor on a semantics that
- assigns objects to predicates. It's solution is (must be)
- independent of the question of reification.
