I'm not sure if I like this paper (it seems to be trying to do too much), but it did contain something new to me - Yablo's non-self-referential version of the Liar Paradox: for every natural number n, let S(n) be the statement that for all m>n S(m) is false. Also there is a funny non-self-referential formulation by Quine: “Yields falsehood when preceded by its quotation” yields falsehood when preceded by its quotation.
Yablo's version looks like unrolled infinite loop of function
Not to me it doesn't. Yablo's version has a "forall" that your translation misses. So in Yablo's version there's no consistent way to assign truth values to S(n), but in your version we could make S(n) = "n is odd" or something.
Not exactly. My version is incorrect, yes. But there is, uhm, controversial way of consistent assignment of truth values to Yablo's statements.
In my version n-th step of loop unrolling is
or
Yablo's version
or
If we extend set of natural numbers by element omega such that
Than we can assign S(n)=false for all n in N, and S(omega)=true.
Edit: Oops, second version of Yablo's statement, which I included to demonstrate why I had an idea of loop unrolling, is not consistent when n equals omega. Original Yablo's statement is consistent although.
Edit: Meta. The thing I always hated about my mind is that it completely refuses to form intuitions about statements which aren't directly connected to object level (but then what is object level?).
Edit: Meta Meta. On introspection I don't feel anything about previous statement. Pretty damn consistent...
