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.

I really don't see how everyone did not immediately see

And algorithm H is wrong about algorithm D because algorithm D contains a copy of algorithm H and does the opposite.

The confusing part is how an intelligent person can

 Every average third grader knows that a contradiction
States that both a statement and its negation are true.  And if a formal system can reach a contradiction through a series of truth preserving operations from its axioms, that means both statements are proven true.
 From *there*, the principle of explosion is applied, demonstrating that the system that proved the contradiction is useless.
