Another Logician [TM] jumps in. I have no idea what the fuck anyone is talking about anymore--there was something about near-death and pre-birth experiences--so I'll just limit myself to technical matters. I'll just mention as an aside that Samuel Beckett has always claimed to have clear memories of life before birth. It was, apparently, horrible. It's hard to disagree with him after reading his complete works, espe- cially, in this particular case, _The Unnameable_. >-As a Logician (yes, I am also that), I can tell you that this is not true. >-No Mathematical theory can be employed to prove its own consistency ... >-unless it is inconsistent. No Mathematical theory strong >enough to encompass Peano arithmetic< can prove its own consistency. There are specially designed toy systems that can prove their own consistency. Raymond Smullyan once designed a special language SELF (Smullyan's Easy Language For) that made self-reference extremely easy. > I must disagree.

It all goes back to Mathematical intuition in the end. > >WTF are you talking about? The integers don't exist? Huh? He's talking about, that FALFTWK, it is mathematically Conceivable that the notion of infinite sets Are Self-Contradictory. Perhaps Mr ">" isn't really aware that he's a closet Platonist. > And what's >this "Axiom of Infinity"?

This is now followed by an irrelevancy, as Mr ">->" hasn't revealed what tenets of "Quantam Theory [sic]" have been PROVEN true. >-The Aspect experiments (which you refer to) did not prove the Copenhagen >-version of Quantum Theory. Please, it is the Copenhagen ``interpretation''. As such it is not really subject to proof; CI is an agreement to continue to use certain good old fashioned terminology to describe quantum stuff, but then to give up cer- tain good old fashioned causality notions. The set of classical notions cannot all be simultaneously applied to quantum stuff. MW reverses the above, keeping classical causality but freaking on the ontology. >Do you know the difference between a formal system (like quantum theory) >and a theorem of that system (existence of local hidden variables)? Let's see: ``quantum theory'' is not a formal system. I'm not even sure that ``quantum theory'' is. Are we speaking in Tongues [TM] today? The existence of LHV is not a theorem. Their non-existence usually is, in most quantum theories. Note the plural. >Maybe they don't get to that until Graduate Logician School. I wouldn't know. I learned my Logic on sleazy streetcorners. >Look, calling yourself a Physicist or a Logician [TM] isn't going to impress >very many people on this net. You're right. My calling you a Loudmouth [TM] isn't going to impress very many people either on alt.flame, although I'm sure Peed [TM] will try to find a way; things must be pretty boring in Illinois at this time of year. ucbvax!garnet!weemba Matthew P Wiener/Brahms Gang/Berkeley CA 94720 I give up. Maybe Wiener was right: they ARE gibbering morons.--P Torek
