gimel Posted January 1, 2008 Posted January 1, 2008 The Australian philosopher colin leslie dean points out Godels theorem is invalid because it uses invalid axioms ie axiom of reducibility it is the biggest fraud in mathematical history everything dean has shown was known at the time godel did his proof but no one meantioned any of it http://gamahucherpress.yellowgum.com/books/philosophy/GODEL5.pdf look godel used the 2nd ed of PM he says “A. Whitehead and B. Russell, Principia Mathematica, 2nd edition, Cambridge 1925. In particular, we also reckon among the axioms of PM the axiom of infinity (in the form: there exist denumerably many individuals), and the axioms of reducibility and of choice (for all types)” note he says he is going to use AR but Russell following wittgenstien took it out of the 2nd ed due to it being invalid godel would have know that russell and wittgenstien new godel used it but said nothing ramsey points out AR is invalid before godel did his proof godel would have know ramseys arguments ramsey would have known godel used AR but said nothing Ramsey says Such an axiom has no place in mathematics, and anything which cannot be proved without using it cannot be regarded as proved at all. This axiom there is no reason to suppose true; and if it were true, this would be a happy accident and not a logical necessity, for it is not a tautology. (THE FOUNDATIONS OF MATHEMATICS* (1925) by F. P. RAMSEY every one knew AR was invalid they all knew godel used it but nooooooooooooo one said -or has said anything for 76 years untill dean the theorem is a fraud the way godel presents it in his proof it is crap
Mr Skeptic Posted January 2, 2008 Posted January 2, 2008 What are you on about? Axioms are always valid by definition, unless they contradict themselves.

Could you say an example? What do you mean by contradicting themselves? What would/could a contradiction be?
Strange Posted April 28, 2018 Posted April 28, 2018 2 minutes ago, Lasse said: Could you say an example? What do you mean by contradicting themselves? What would/could a contradiction be? As Mr Skeptic hasn't visited for 7 years, let me have a go... Axiom 1: The natural numbers are defined to start at 1 Axiom 2: 0 is defined to be the first natural number. There you go. Two reasonable axioms that contradict one another and so can't be used at the same time.
Lasse Posted April 28, 2018 Posted April 28, 2018 Thank you Strange. Kind of expexted you You are a special kind of angel Strange I wonder where from the energy!?
taeto Posted June 20, 2018 Posted June 20, 2018 Is the Ramsey quote really correct, did Ramsey write anything that stupid? A "tautology" is usually a statement that is always true. If you build a theory axiomatically, then the axioms are always true, by construction, in that theory. And anyway, supposing you throw out a number of axioms, it of course would make arithmetic statements even more undecidable than they are already. Eventually you might no longer be able to prove that this is so. But if that is your intention, then you could instead also close your eyes, put your fingers in your ears and go LALALALALA and avoid being disturbed by facts that way.
