No. I'm beginning to get bad feelings about this. This is another proof (well, pretty much the same one, actually) of the undisputed fact that the width is infinite isn't it? Anyway, next.... Sylvia.

Can you parse 'start with the assumption' paragraph yet? If you can compute all permutations infinitely wide then isn't that all reals? That's all from me I'm homeless in a few hours so I'll need my iPhone battery to check my bank account. Herc

This is one of several posts by several different posters who point out that if one accepts several axioms and accepts the underlying logic, then one automatically accepts any statement that is derived from such, whether one likes it or not. Another poster pointed out that Cantor's Theorem is a finitistic statement that has a finite proof in ZFC. I don't dispute that "ZFC proves Cantor's Theorem" is uncontroversial and not open to debate, but there's a big difference between "ZFC proves Cantor's Theorem" and "Cantor's theorem is true." One can accept the former yet reject the latter. I will consider a poster who makes a claim of the form "I accept A, and I accept A->B, (and I accept Modus Ponens), yet I don't accept B," to have crossed the line beyond which they deserve five-letter insults. But so far, I have yet to see Herc cross that line. If one accepts all the axioms of ZFC and all of FOL, then one must accept Cantor's Theorem whether they like it or not, but Herc apparently _doesn't_ accept all of the axioms of ZFC (at least not enough axioms to prove Cantor). On the contrary, Herc considers ZFC to be a "religion." So I agree with Nguyen that we shouldn't support inconsistency in reasoning, but until Herc claims that he accepts enough axioms and logic from which to derive Cantor, he hasn't posted any inconsistency in reasoning yet.
