I'm actually not convinced that Olcott understands what a definition is. I've frequently asked him for definitions and he invariably responds with an example or an analogy (assuming he responds at all). He doesn't get that examples don't take the place of definitions. Examples can be useful for clarifying definitions, but they aren't particularly useful on their own.

That claims what it means to have the truth value 'true' (or at least it would if you defined AtomicFacts in a coherent way). It doesn't in any way clarify what you think it means for something to not have a truth value.

Good.  So when you say "The truth value of (∀ x, S(x) ≠ x) does not exist in Q", you mean "(∀ x, S(x) ≠ x) is unprovable in Q", which is commonly known.

Not really. It is normally thought of as undecidable

False.  It means that there are statements in the language of Q that have *only* an infinite connection to the axioms of the system.

I really don't see how everyone did not immediately see
that the requirement for H to correctly report the halt
status of input D that does the opposite of whatever H
reports is a moronically stupid requirement within the
first five minutes that this requirement was made.
 In other words, you don't understand that if this was algorithm H:
 
I spent 10,000 hours on it over 22 years.
It has always been fucking nuts to require a machine
to report on the behavior of another machine that
does the opposite of whatever it reports.
Are you too fucking stupid to see this?

My 28 year goal has been to make
"true on the basis of meaning expressed in language"
reliably computable for the entire body of knowledge.
The complete structure of this system is now defined.
The entire body of knowledge expressed in language is
comprised of two types of relations between finite strings:
(a) *Axioms* Expressions of language that are stipulated to be true.
My system bridges the analytic/synthetic distinction by
expressly encoding all empirical "atomic facts" in a formal
language such as CycL of the Cyc project.
(b) *Inference Rules* Expressions of language that are semantically
entailed syntactically from (a) and/or (b).
