- I hope I don't have to ask for the longer reply!
-
- But, I don't understand how using unreified predicates instead of
- objects helps avoid set theoretic paradoxes. Grelling's paradox
- uses only a predicate, and (unless I'm very confused) does not
- require reification.
-
- You said earlier that the REAL trick is denying Separation.
- That seemed promising. Can I follow up a bit?
-
- I can talk about everything all at once. But everything all at
- once is not a completed totality. Check.
-
- I can restrict my quantifiers, too. I suppose that denying Separation
- means that there are some ways I cannot restrict them. For example,
- I CAN say something like, "Everything blue is also square." May
- I also say, meaningfully, "Every quantifier that has another
- quantifier in its range commits its employer to abstract objects"?
-
- (I am not at all interested, right now, in whether I can say that
- TRULY, only MEANINGFULLY.)
-
- Can I meaningfully say, "Some quantifiers have themselves in their range."?
-
- I won't insult you by leading you down such an obvious path. You can
- see better than I can where this is going.
-
- Where do you get off? (Is the problem inherent in speaking of a "range"?
- I will be surprised if it is.)
