What makes anyone thing the universe "began to exist?" For all we know it's like the negative integers ..., -3, -2, -1. Every element has a predecesso...

The uncaused cause is God. That would be Craig's point. If you find it sensible I guess we'll agree to disagree.

I'm stating William Lane Craig's argument in order to characterize it as disingenuous and silly. Was that unclear in my post? "Premise one: "Whatever ...
August 09, 2017 at 03:38
Disclaimer, I haven't read the rest of the thread and I don't know where it's gotten to by now. I did happen to look at William Lane Craig's cosmologi...

I think it might be helpful to distinguish the issue of whether existence is a predicate, with the issue of how philosophers handle fiction. That latt...

?x?S (x ? S) That would be the formal way, since x ? S is a predicate. Technically that is a convenient abuse of notation. Everyone writes it that way...

I do not believe the existential (or universal) quantifiers may stand alone. Rather there must be a unary predicate P so that you can write ?xP(x). If...
July 23, 2017 at 23:15
Ok. But now that I've explained it to you, your understanding should be excellent :-) It's true that there are logics where time is modeled, for examp...
July 23, 2017 at 15:50
Yes I think I see your point. If we think of it as a process, as in the execution of a computer program, then we are just flipping states back and for...

Logical implication is not causation. They're two completely different things. Have you ever seen the truth table for implication? I am wondering, do ...

A contradiction in sentential (aka propositional) logic, a contradiction is the statement "P ^ not-P" for some proposition P. There is no requirement ...
July 23, 2017 at 03:25
No. The assumption that we can form such a set leads to a contradiction, showing that unrestricted comprehension can not be allowed. Please read the W...

That's not Russell's paradox.
July 22, 2017 at 22:47
Yes exactly. Our intuition is that a tiny change in the input conditions will smooth out over time and make no difference to the future evolution of t...

If you quote you should quote literally. If you are paraphrasing someone, you should not make it look like you're quoting them. A stylistic nitpick, t...
July 20, 2017 at 04:15
Why are you quoting words I didn't say in my post?
July 19, 2017 at 14:40
A more precise statement can be made. It is that under a deterministic iterated system, points (or states) that start out very close together may end ...
July 19, 2017 at 05:40
Your erudition seems to have overtaken your common sense and your manners. You are incapable of explaining, only insulting. I'm using individual quote...

In the Zalamea paper on Peirce's continuum, Zalamea says on page 8: "As we shall later see, this synthetical view of the continuum will be fully recov...
February 23, 2017 at 22:07
Your full quote earlier was: There is only one way to read this. * For any value of N whatsoever, 2^N > N. * Therefore, a power set always has more me...
February 23, 2017 at 20:20
It's a bad argument. Suppose I like to juggle, and the local government forbids juggling. I say, "I have a right to juggle, especially in the privacy ...
February 23, 2017 at 20:04
That does not follow. It must be proved. That's Cantor's theorem. Well worth looking at since it's a beautiful little proof that gives us an endless h...
February 23, 2017 at 20:02
Well when you put it THAT way it's totally CLEAR. LOL. I see that Peirce has some jargon associated with him. From Googling around I think being triad...
February 23, 2017 at 06:14
Biology, that's interesting. I thought sign relations were some kind of postmodern talk I don't know anything about other than that Searle thinks Derr...
February 23, 2017 at 01:53
This is actually a great mathematical question. If you assume the Axiom of Choice (AC), then all sets have a well-defined cardinality that is the smal...
February 23, 2017 at 01:29
I started reading the Zalamea paper, Googled around, and found a pdf of his awesome book Synthetic Philosophy of Contemporary Mathematics. I'm enthral...
February 23, 2017 at 00:31
You can take my word for it that .999... = 1 is a theorem of nonstandard analysis. But actually you don't need to take my word, I provided a proof abo...
February 22, 2017 at 23:52
As it happens, .999... = 1 is a theorem even in nonstandard analysis. This is easily shown. The hyperreals are a model of the first-order theory of th...
February 22, 2017 at 22:39
My problem! LOL. I haven't read anything after this morning. No harm no foul. For what it's worth, I've often wondered about the relation between the ...
February 22, 2017 at 05:18
Your characterization of me is quite unfair. One, to lump me in with Tom, whose erroneious and confused mathematical misunderstandings I've refuted an...
February 21, 2017 at 21:44
I agree with that. Calling real numbers locations seems to avoid a lot of the philosophical issues about the nature of points. I've started reading th...
February 21, 2017 at 21:23
Good point. No pun intended. The answer is in the concept of "occupies a place." If we view the real numbers as specifying locations on a line, and we...
February 21, 2017 at 21:08
A point is that which has no part. Euclid was right about that. You can't subdivide a point and a point has no sides. It's sophistry to claim otherwis...
February 21, 2017 at 20:47
Can you explain (so that a philosophical simpleton like me could understand it) how mathematics has failed to successfully deal with continuity? Moder...
February 21, 2017 at 20:24
What do you mean by "bigger?" Bearing in mind that there are countable models of the reals? https://en.wikipedia.org/wiki/L%C3%B6wenheim%E2%80%93Skole...
February 21, 2017 at 19:34
You are each using different definitions. This is the fallacy of ambiguity. Surely we need not argue about this any more. I have humbly offered the wo...
February 21, 2017 at 04:12
I'll certainly take that to heart :-) Can you (or anyone) supply some of relevant Bergson and Pierce links that would shed light on the relation betwe...
February 21, 2017 at 02:23
Please locate that quote of mine, I can't find it and don't remember saying it. I probably said reordered and definitely well-ordered, but not disorde...
February 21, 2017 at 00:13
We can well-order the reals. https://en.wikipedia.org/wiki/Well-order#Reals I mention this because it's a counterexample to the intuition that a set c...
February 20, 2017 at 23:39
I don't know if it's a "substantial" difference. It's certainly a difference. The rationals are foozlable and the reals aren't. Even in countable mode...
February 20, 2017 at 20:22
You do agree they're foozlable, right? I just want to make sure I'm understanding you. I really miss your bug-eyed avatar from the old forum :-)
February 20, 2017 at 20:13
The reals in their usual order are a continuum. They can be reordered to be discrete. Counterintuitive but set-theoretically true. Order is important ...
February 20, 2017 at 20:06
Which has absolutely nothing to do with the question of whether a given set is foozlable -- able to be bijected to the natural numbers. I don't want t...
February 20, 2017 at 20:00
I went back through this thread from the beginning. Finally on page 11, this quote is the first mention of mathematical countability. The above quote ...
February 20, 2017 at 19:28
You can certainly well-order an uncountable set. You need the Axiom of Choice to well-order the real numbers, but you do not need Choice to show the e...
February 20, 2017 at 16:55
This is not true. A set is defined as countable if it can be put into bijection with the natural numbers. By this definition we can then show that the...
