Admitting defeat I bow out, parting with a helpful parting comment, that should you for some reason care about the actual mathematical content of the incompleteness theorems it might be a good idea to read a text on the subject, such as Torkel Franz�n's _G�del's Theorem_. -- Aatu Koskensilta (aatu.koskensilta(a)uta.fi) "Wovon man nicht sprechan kann, dar�ber muss man schweigen" - Ludwig Wittgenstein, Tractatus Logico-Philosophicus

MoeBlee's confusion is very understandable. Although Erik Freitnautzer's morally suspect half-brother of the same name was non-standard the two were nevertheless elementarily equivalent. -- Aatu Koskensilta (aatu.koskensilta(a)uta.fi) "Wovon man nicht sprechan kann, dar�ber muss man schweigen" - Ludwig Wittgenstein, Tractatus Logico-Philosophicus

That is not mentioned in MacTruffleboygen's 'Encyclopedia Of Standard and Nonstandard Saints and Sinners'. In fact, as I recall, it is mentioned that not only did Freitnautzer lack siblings but he lacked parents. A curious case, to say the least. Sure, many people have claimed to be parent to Freitnautzer, but all have been discredited by the fact that parentage would violate the para-congruent anti-well founded symmetry of his non-finitary existence. [Note: I spelled 'MacTruffleboygen' with a 'b' rather than with an umlaut over an 'x' as is actually correct but overly pedantic.] MoeBlee

Well, given the non-existence of his half-brother, that follows vacuously. Though it is still an open question whether the non- existence of his elementary equivalent half-brother implies the non- existence of Freitnautzer himself. MoeBlee |
