It says you are an academic physician, just out of curiosity, which university are you affiliated with in N.C.? UNC?
I'm on the faculty at Duke's medical school and at Duke University Hospital in the departments of internal medicine (hospital medicine program) and pediatrics (infectious diseases); I was a fellow at Harvard Med from 2004-2007, and they seem to have forgotten to cancel my ID card since I left, so I still have online access to all of their libraries.
Also, I'm sure that there are quite a few different methods by which the proof has been refuted over the hundreds of years since its insception, however, these may not turn out to be tautological and thus not valid by modern standards of logical analysis.
There are many modern refutations. I'm not a logic expert, but I'd think that a tautological refutation would be inherently flawed. After all, isn't that the main criticism of logic in general? A logical tautology, including in the form of a God proof, doesn't need to bear any resemblance to reality, because by definition a tautology is self-contained. Videcorspoon is the local logic expert, though.
Are there any writings from other religions that might qualify as philosophic proofs of the supernatural?
That's a great question. I know that there are proofs in both Judaism and Islam, with the most famous of all being Avicenna's proof. He was Muslim and very strongly influenced by Aristotle. His writings were probably the strongest influence on the philosophy of Aquinas. I'm trying to recall if Maimonides, who was the most famous Jewish philosopher in the middle ages, had a god proof in Guide for the Perplexed
, but I'm not sure.
As for other traditions, I doubt it -- I don't think logic and rationality ever became important areas of philosophy, so I don't know that supernatural beliefs were ever put to that kind of test -- simply because the whole idea of "supernatural" presupposes a certain kind of rationally discernible natural order, right?
