Oh sorry I didn't realize that. Thanks for clarifying.

You raised a lot of really good points in this post and it's late so I only want to respond to this one point and I'll aspire to get back to the rest ...
June 01, 2018 at 07:33
I did acknowledge that people are doing this research and that they're serious people. And I simply stated that if I met one of them I'd offer up the ...
June 01, 2018 at 05:43
Ah ... a while back you objected that I misquoted you saying that incompleteness was on point here. But in fact I believe I was originally correct. Yo...
May 31, 2018 at 04:47
Ok herewith my response to the deferred post. But no, you're just restating your bias, not explaining it. "Q: Why is primes a simple proof by contradi...
May 31, 2018 at 03:56
I plead tragic ignorance of Aristotelian logic. Perhaps I over-identify the word logic with the standard predicate logic used in mathematics. The para...
May 31, 2018 at 03:55
Ahhhh, very interesting article. I learned something. I do feel a tiny bit sandbagged in the sense that you've had this somewhat obscure topic in mind...
May 30, 2018 at 21:25
Ah, you must be working from knowledge of paraconsistent logic that I lack. Reference for the above fascinating factoid?
May 30, 2018 at 03:12
Sorry, I overstepped my knowledge. I don't know anything about Aristotle. Poor Frege, such a brilliant and original thinker, forever remembered for hi...
May 30, 2018 at 03:10
Well that's the conventional wisdom, pretty much universally accepted. But I wouldn't say that we don't need unrestricted comprehension (I don't know ...
May 30, 2018 at 03:07
This is exactly how I got in trouble last time. Conversating back and forth while deferring responding to the important earlier post. But a few though...
May 30, 2018 at 02:46
Ok. Just wanted to make sure you accept law of excluded middle and proof by contradiction. Will do. I got in trouble once around here when I deferred ...
May 30, 2018 at 01:56
That didn't even make sense. I do remember reading it now. I don't follow your point at all. We assume there's a largest prime and derive a contradict...
May 29, 2018 at 23:34
Link please, I didn't see it. But it wasn't an argument, since I'm merely stating what every single mathematician agrees with. I'm asking you a questi...
May 29, 2018 at 23:01
Uh ... LOL. That made me chuckle. It's because the form of the two proofs is identical: * Assume there's a largest prime. * Derive a contradiction. * ...
May 29, 2018 at 22:32
Do you regard the proof by contradiction that there's no largest prime a conundrum or paradox? Why or why not? In other words: The assumption that the...
May 29, 2018 at 22:26
I addressed that point in my earlier response to @MindForged. Naming is generally a matter of historical accident. Is the Axiom of Choice an axiom, Zo...
May 29, 2018 at 17:59
You raised a number of interesting points. Before I respond in detail, it would help me to understand your point of view if you could tell me in clear...
May 29, 2018 at 17:46
MindForged, you are completely misunderstanding the difference between a veridical paradox and a plain old proof by contraction. Moreover, Russell's p...

The barber is shaved by Occam's razor.
May 29, 2018 at 00:41
Good God Almighty. Russell's paradox was resolved in 1922 by the axiom schema of specification.
May 28, 2018 at 22:34
Well I gave it the old college try. At least @apokrisis didn't show up to hurl gratuitous insults. I'm outta here again.
May 26, 2018 at 17:52
LOL. I ask again: Why is it that in one case, you invoke the standard mathematical formalism to explain or ignore the underlying philosophical issues;...
May 26, 2018 at 17:49
Even if that were true, it wouldn't answer my question.
May 26, 2018 at 17:45
Yes, that is the mathematical formalism. So in this case you fall back on the mathematical formalism to ignore the philosophical paradox; but in the c...
May 26, 2018 at 17:35
Which has what to do with anything I wrote? Let me tl;dr this for you. Why are you so focussed on a particular paradox of Riemann integration, when it...
May 26, 2018 at 16:22
I have a question for you. Gabriel's horn is a paradox of Riemann integration, accessible to students of freshman calculus. As others have noted it's ...

In the synagogue one day the Rabbi kneels and puts his forehead to the floor and says, "Before you oh Lord, I am nothing." The Cantor puts his forehea...
March 27, 2018 at 23:18
I don't know your background so I can't say. But here is a free pdf of Shoenfeld's classic text on Mathematical Logic. It's one of the standard grad-l...
March 27, 2018 at 01:55
That's right. I noted that there is no general definition of number in mathematics. A well-known and true observation. For whatever reason, this simpl...
January 19, 2018 at 22:14
No. It's not. That's the point. i is a number but it's not a quantity. That's a counterexample to your idea that a number is something that is a quant...
January 19, 2018 at 22:13
My remark was intended as lighthearted. What the meaning of "is" is was very big in American popular culture during that particular scandal. This is t...
January 19, 2018 at 06:02
Your complete misunderstanding and lack of comprehension of category theory and mathematical structuralism was evident to several other posters the la...
January 17, 2018 at 02:43
I did not write the quote you attributed to me. What is your attitude problem? I stated originally that there is no general definition of number in ma...
January 17, 2018 at 02:17
I don't want a definition. I merely pointed out that there isn't one in math. You agree with this by now, yes?
January 17, 2018 at 00:35
Hope nobody here mortgaged their house to go all in at $19k. It's a crypto bloodbath out there at the moment.
January 16, 2018 at 22:52
I certainly can't understand how you would have gotten that impression. Many specific types of numbers are defined within set theory. But there is no ...
January 16, 2018 at 22:39
The quaternions are numbers whose multiplication is not commutative. The transfinite ordinals are numbers whose addition is not commutative. How weird...
January 16, 2018 at 07:29
There's no definition of number in ZFC. In ZFC we have a definition of natural numbers, and we can make definitions of the integers, rationals, reals,...

Bill Clinton made that very same argument to try to wiggle out of a sex scandal. In the end he lost his license to practice law and was impeached (but...
January 16, 2018 at 07:16
Yes that's an interesting point. Philosophers and logicians have struggled to define what a number is. Mathematicians don't really care that they have...
January 16, 2018 at 03:26
The list of posts I need to respond to is growing faster than my available time to respond. I'm plugging along though. Like the guy writing his autobi...
January 16, 2018 at 00:04
Saying that a number is anything that's number-like is a circular definition. No better than the poster above who said that a quantity is anything tha...
January 14, 2018 at 22:37
Ok I'll play. Four questions. * What is quantity? * The imaginary unit i with i^2 = -1 ... what quantity does it represent? * Do you regard i as a num...
January 13, 2018 at 16:00
It's a philosophical curiosity that there is no definition of number in mathematics. In other words if you major in math, get a Ph.D. spend a career a...
January 12, 2018 at 18:21
The rightness or wrongness of Tegmark's idea doesn't matter so much as the fact that I can add, "and Tegmark agrees with me!" when I argue the same po...
January 12, 2018 at 05:55
That fits nicely with some thoughts I have. The risk isn't computers acting like people. The risk is people acting like computers. Every time you're t...

What a wonderful thought. In the old days people had phone numbers like MUrray Hill 5-9975. You'd dial the MU characters on your dial phone. In the 19...
January 12, 2018 at 02:17
It it intellectual rebuttal that's important here? Or the emotions stirred up by family dynamics? Perhaps this is more of a psychological problem than...

That was in the old days of sound monetary policy. As David Stockman notes, that was the time of President Dwight Eisenhower and Fed Chairman William ...
