Dependent or Countable Choice seem reasonable, but a blanket statement for all sets seems unjustified. Uncountable sets always lead to infinite regression, whether due to being divided into an uncountable number of partitions, or due to having an uncountable partition, when trying to explicitly define a well order. We explored that in Well Ordering the Reals. Maybe you missed that thread, but that's hard to believe... There's the matter of not considering proper subsets to be necessarily smaller, when the subset relation is always as transitive as quantitative inequality. The proper subset always has the same elements, minus some nonzero number. That's less. The proper superset's always more. Any theory that violates that basic principle is rather suspect. x+y=y+x x+0=x x>0->x+y>y x<0->x+y<y ....basic definitions, or parts thereof.

It would also be nice to have an alternative to cardinality, as a definition of infinite size, entertained without so much antagonism, but hey! Whaddya expect from sticklers, mathematikers and logikers? A lot of what Lester does, and remember that he started this thread, is stir the pot. Most are sheep and follow, some are shepherds, leading and chasing, and some really can't follow or lead, but stick around and make a presence anyway, and keep the dogs and rams a'boutin'. So, what's your opinion of infinite-case induction, IFR and N=S^L, and multilevel logics, again?

But, the size achieved per iteration, or the Big O value, if you will, can be expressed formulaically so that, if you know the size of one set, you can tell the size of the other, at any point in their mutual iterations. We don't get into trouble here, because we don't try to define the boundary between finite and infinite as a definite location, but only relate the size of two structures defined in bijection with N. >>> I find it hard to beleive you don't understand this.

That's a very basic concept, and not one easily relinquished by most that have thought about it before being "educated".

It predicts the nonzero possibility of reorganizing a solid finite sphere into two solid ones of the same size. In other words it magically makes space and matter by dictate. It says that, even though only half the integers are even, there are as many even integers as integers. Can we please not totally corrupt logic itself? Not all logic is deductive.

Well the problem is that you didn't claim my application of L'Hospital's rule was invalid. You claimed the rule itself was invalid. So perhaps you'd like to show how the rule itself is invalid or why my application of the rule is? ~v~~

I assume there are things which can be true or not whereas you assume you already understand which things are true or not and how to work with their truth in mechanical terms while I'm interesting in finding out how to demonstrate their truth in mechanical terms to begin with and how to work with that truth or lack of it in mechanical terms. > do please assess each of those >assumptions for certitude when assessing the statement's truth, but when >speaking of the "mechanics" of deduction or induction it doesn't help to >worry about "assuming". Of course, Tony. You just take assumptions for granted. I don't. That's the whole context of the discussion. Mathematikers and empirics can't be bothered to demonstrate their assumptions. > That's inherent to the process, if your process >has anything to do with science. You "assume" there is such a thing as >truth. Is there? What's the alternative? Well it's about time you started to ask questions, Tony, instead of making problematic proclamations of mathematical certitude. I don't assume there is any such thing as truth. I just posit a mechanism of universal tautological contradiction and show that one alternative is self contradictory so I assume the other alternative is universally characteristic of everything which is not self contradictory and that is what I call true just as I call self contradiction false. In other words it's the mechanics underlying the determination of true and false that I'm trying to get at and not just the proclamation of true and false and the binary mechanics of working with those results. You on the other hand seem hell bent on explaining the mechanics of working with the results of true and false without explaining the mechanics of determining those circumstances. Mathematikers can't bring themselves to call the results "true" and "false" with straight faces so they just call them "truth values" instead of true and false. Let me ask you something, Tony. When you send off for some truth value according to "true(x)" and it returns a 1 or 0 or whatever, how is the determination of that "truth value" made? And if it's just made in accordance with the manipulation of other "truth values" how are those "truth values" determined? Or is it all just a bunch of running "truth value" manipulations with no beginning or end? If that's all they are then you have no reason to call "truth values" "truth" values and you might just call them what they are 1's and 0's because that's all they really are. So what all this nonsense comes down to is that your "truth values" have no beginning in actual mechanical terms because they're given to you by assumption and not demonstrated in mechanical terms and all those conjunctions and conjunctive manipulations you describe are just so many arbitrary translation rules to work with otherwise meaningless 1's and 0's. ~v~~ |
