2+3=5, that relationship between the pure numbers 2,3 and 5 doesn't change, manifestly or otherwise. *> I was not saying you would find an arithmetical relation in spacetime,* True, you were saying the exact opposite, you were saying you could find spacetime in the relationship between pure numbers and so everything comes from pure numbers, but I'll be damned if I can see how you reached that conclusion. *> I was saying there is a correspondence between arithmetical > computations, and the subjective time evolution of spacetime * Arithmetical computations don't change so there can't be a correspondence between them and the evolution of spacetime or with anything else that can change. >> OK, in platonic heaven all computations exist, and I mean all of them, >> the incorrect ones as well as the correct ones, and only a physical Turing >> Machine can seperate the correct from the incorrect computations.

Obviously, but in such an infinite set nearly all the computations in it would be self contradictory, I believe the technical term for that is "wrong", although some prefer the word "stupid". > * What is an incorrect computation? Incorrect with respect to what? * Incorrect with respect to the laws of logic and the Peano Postulates, the very thing used to give formal definitions to numbers, the very thing that you and Bruno claim sits at the foundation of reality. *> So long as the computation is the result of a functioning Turing machine > nothing it does can be called an "incorrect computation".* A functioning Turing Machine does not take its marching orders from the Peano Postulates or from the numbers they define, a functioning Turing Machine only does what its program orders it to do and even then only if that order does not violate physical law. Depending on the program you could have the functioning Turing Machine output that 2+3 is 4,5,6,-17, 6.02*10^23. or an infinity of other things, but only one of those programs treats numbers the way Peano said they should be treated, and thus out of an infinite of possible programs only one will produce an output consistent with arithmetic. >* Note the context is we're talking about arithmetical computations, not > physical machines * And speaking of self inconsistency, a non-physical Turing Machine can not be functional because, just like all machines, a Turing Machine must be able to change and nothing can change except matter/energy. There is a reason it's called a Turing Machine and not a Turing principle. > > *> I thought you "weren't religious".

You've saved me some time, now I won't have to go looking for my rubber stamp. John K Clark -- You received this message because you are subscribed to the Google Groups "Everything List" group.
