What unit of measurement is required for counting the natural numbers? Metres? Litres? Hours? Bananas? Obviously, no unit of measurement is required. You can count to ten without having to determine any unit of measurement. Therefore, counting is independent of measuring. Counting is not a "form of" measuring. — Luke
Perhaps you're right that meaning isn't the correct word. If I said we remove a concept from its worldly or physical referent, would that be better? We care about first, second, third, and not first base, second base, third base. So how would you describe that? I'm focusing on ordinality itself and not the things ordered. So you're right, meaning was an imprecise word. — fishfry
There is no temporal reference. — fishfry
Ok. I agree that I'm having trouble precisely defining abstraction and I sort of see your point. But ordinal numbers are purely about order, but they're not about any particular things being ordered. How would you describe that? It's not meaningless, yet it refers to nothing in the world at all other than the pure concept of order. Which you don't seem to believe in. — fishfry
But order is not essential to numbers, it's imposed afterward. — fishfry
. I get that you are drawing a distinction between the mathematical formalism, in which order is secondary to the existence of numbers; and philosophy, in which order is an essential aspect of numbers. — fishfry
A schoolkid must have a height, but it could be any height. — fishfry
You see it that way. I see it as providing beautifully logical clarity. We have the set of natural numbers, and we have the standard order and we have a lot of other orders, and we can even consider the entire collection of all possible orders, which itself turns out to be a very interesting mathematical object. It's quite a lovely intellectual structure. I'm sorry it gives you such distress. — fishfry
But I have not asserted that a set must have any order at all. The set NN has no inherent order at all. Just like a classroom full of kids has no inherent order till the teacher tells them to line up by height or by alpha firstname or reverse alpha lastname or age or test score or age. Why can't you see that? — fishfry
A contradiction is a proposition P such that both P and not-P may be proven from the axioms. Perhaps you would CLEALY state some proposition whose assertion and negation are provable from the concept of order as I've presented it. I don't think you can. — fishfry
Absolutely agreed. Yes. The essence of a set of numbers is NOT in their order, since we can easily impose many different orders on the same underlying set. Just as the ordering by height is not essential to the classroom of kids, since we can impose a different order; or by letting them loose in the playground at recess, we can remove all semblance of order! Surely you must take this point. — fishfry
Ok. But that's not good enough. I asked how do you call mathematical objects like topological spaces. But justice and property are concepts and abstractions, yet they are not mathematical objects.
If you don't like the phrase, "mathematical object," what do you call them? Sure they're an abstraction, but that's way too general. You see that I'm sure. — fishfry
An object is not a goal. An (American) football is an object, and the goal is to get it across the goal line. You would not say the football is a goal. I think you're way off the mark with your claim that an object is a goal or objective. 5 has no object or purpose. It's just the number 5. A mathematical object. An abstract object, as all mathematical objects are. — fishfry
No, not in the least. How can you say that? That's not even the meaning of the words in everyday speech in the real world. The winner takes first place and the runner up takes second place sometimes (as in a foot race) but not always (as in a weight lifting contest) by being temporally first. You must know this, why are you using such a weak argument? First place in golf goes to the player with the lowest score, not to the player who finishes the course first. This is a TERRIBLE argument you're making here. — fishfry
Math just has the number 5. — fishfry
The problem obviously, is that you, and mathematicians in general, according to what you said above, haven't got a clue as to what a number is. — Metaphysician Undercover
The winner takes first place and the runner up takes second place — fishfry
while we flitter about, inconsequential moths circling your flame. — jgill
To count, in the sense of determining a quantity, is an act of measuring. To "count" in the sense of counting up to ten, is a case of expressing an order, two comes after one, three comes after two, etc.. To call this "counting the natural numbers" is a misnomer because this is nothing being counted, no quantity being determined. — Metaphysician Undercover
Everyone else considers "counting up to ten" to be counting (you also called it "counting", by the way). — Luke
Why should we care about your unjustified stipulation that counting the natural numbers is not real counting or that real counting must involve "determining a quantity"? — Luke
If a flame be a dumpster fire. — TonesInDeepFreeze
Yes, i call it "counting" — Metaphysician Undercover
but the point is that there's two very distinct senses of "counting" and to avoid ambiguity and equivocation we ought to have two distinct names for the activity, — Metaphysician Undercover
If it is the case, that when a person expresses the order of numerals, one to ten, and the person calls this "counting", it is interpreted that the person has counted a quantity of objects, a bunch of numbers, rather than having expressed an ordering of numerals, then the interpretation is fallacious due to equivocation between the distinct meanings of "counting". — Metaphysician Undercover
But what is the justification for your stipulation that counting natural numbers is not real counting or that real counting must involve "determining a quantity"? — Luke
The point is to avoid equivocation which is a logical fallacy. — Metaphysician Undercover
numbers are not even countable objects in the first place, they are imaginary, so such a count, counting imaginary things, is a false count. Therefore natural numbers ought not be thought of as countable. — Metaphysician Undercover
And we described counting as requiring objects to be counted. I distinguished a true count from a false count on this basis, as requiring objects to be counted. Clearly, if the objects counted are not actual objects, but imaginary objects, it is not a true count. — Metaphysician Undercover
Look, I think it's very important for a rigorous mathematics to distinguish between counting real things, and counting imaginary things. This is because we have no empirical criteria by which we can determine what qualifies as a thing or not, when the things are imaginary. Therefore we can only count representations of the imaginary things, which exist as symbols. So we are not really counting the imaginary things, but symbols or representations of them, and we have empirical criteria by which we judge the symbols and pretend to count the imaginary things represented by the symbols. But this is not really counting because there are no things being counted. — Metaphysician Undercover
Since one sense of "counting" involves counting real things, then why not call this "real counting"? — Metaphysician Undercover
Or, as Jerry Seinfeld reminds us, taking Silver in the Olympics just means you're the best of all the losers. — TonesInDeepFreeze
The original paper is in Jean van Heijenoorts's 'From Frege To Godel'. — TonesInDeepFreeze
You have attempted to argue that counting natural numbers, or counting imaginary things, is not true counting, and that to call this "counting" is a misnomer. — Luke
Let's get this straight. I am not talking physical referents here. I am talking space and time, which are conceptual. — Metaphysician Undercover
The issue is that when we remove the physical referents (required for "counting" in the sense of determining a quantity, as the things counted), for the sake of what you might call purely abstract numbers, the meaning of the numbers is grounded in the abstract concepts of space and time. — Metaphysician Undercover
Numbers no longer refer to physical objects being counted, they refer to these abstract concepts of space and time. — Metaphysician Undercover
Now, we have only deferred the need to refer to physical existence, because if our conceptions of space and time are inaccurate, and the ordering of our numbers is based in these conception of space and time, then our ordering of the numbers will be faulty as well. You seem to think that in pure mathematics, a logician is free to establish whatever one wants as "an order", but this is not true, because the logician is bound by the precepts of "logic" in order that the order be logical. — Metaphysician Undercover
For example, a self-contradicting premise is not allowed. — Metaphysician Undercover
As long as my order is reflexive, antisymmetric, and transitive, it's allowed. And for the umpteenth time (umpteenth is an ordinal!!), a contraction is a statement P such that both P and not-P can be proved from a given set of axioms. A contradiction is NOT merely something that offends your intuition. In math we get quite accustomed to having our intuitions challenged and corrected.
So there are fundamental rules as to the criteria for "order" which cannot be broken. — Metaphysician Undercover
And even if you argue that the order could be a completely random ordering of numbers, the rule here is that each thing in the order must be a number. — Metaphysician Undercover
And every time a logician tries to escape the rule, by establishing a principle allowing oneself to go outside that rule, there must be a new rule created, or else the logician goes outside the field of logic. — Metaphysician Undercover
And the point, is that if the rule is not grounded in empirical fact (physical existence) the logic produced is faulty, and the proposed rule ought to be rejected as a false premise. — Metaphysician Undercover
Surely, "first" does not mean "highest quality", or "best", in mathematics, so if it's not a temporal reference, what is it? — Metaphysician Undercover
Yes that is my point as to how counting order is different from counting a quantity. — Metaphysician Undercover
To count a quantity requires particular things, but to count an order requires only time. — Metaphysician Undercover
However, time is something in the world, and that's why I don't believe in what you call "the pure concept of order". — Metaphysician Undercover
If order is not essential to numbers, then something else must be, because to be a concept is to be definable according to essential properties. I propose, then that quantity is essential to numbers. Do you agree? — Metaphysician Undercover
If for example you make an order, or a category, of odd numbers, or even numbers, or prime numbers, it is something about the quantity represented by the number which makes it belong in one or more of these categories.[/quote}
What makes 6 an even number is that it's divisible by two; or equivalently, that it's residue class mod 2 is zero. That's how we recognize 6 as an even number.
Here's a more striking example that even you will have to concede. I can recognize 45385793759385938534 as an even number without knowing ANYTHING about its quantity or order. I merely have to note that the low-order digit is even, and appeal to the theorem that a number is even if and only if its low-order digit is.
— Metaphysician Undercover
If it's not quantity which is essential to numbers, as the defining feature of "number" then what do you think is? You've already ruled out order. — Metaphysician Undercover
No, I am saying that if order is secondary to the existence of numbers, then quantity must be primary — Metaphysician Undercover
That's not true at all, it's the fallacy I referred to. The schoolkid must have height, and that height must be the height that the schoolkid has. Therefore it is impossible that the schoolkid has a height other than the height that the schoolkid has, and very obviously impossible that "it could be any height". To make such a claim is clearly fallacious, in violation of the law of identity, because you are implying that a thing could have properties other than those that it has, saying it could have any property. Obviously this is not true because a thing can only have the properties that it has, otherwise it is not the thing that it is. — Metaphysician Undercover
It gives me distress to see you describe something so obviously fallacious as "providing beautiful logical clarity". If you consider circumventing the law of identity as beautiful logical clarity, I have pity. — Metaphysician Undercover
Again, you're continuing with your fallacy. A classroom full of kids must have an order, or else the kids have no spatial positions in the classroom. — Metaphysician Undercover
Clearly though, they are within the classroom, and whatever position they are in is the order which they have. To deny that they have an order is to deny that they have spatial existence within the room, but that contradicts your premise "a classroom full of kids". — Metaphysician Undercover
Above, is your CLEAR example of contradiction "a classroom full of kids has no inherent order". By saying "there is a classroom full of kids", you are saying that there is an order to these kids, they exist with determinate positions, in a defined space. You contradict this by saying they have no inherent order. — Metaphysician Undercover
So, if "a set" is like the kids in the classroom, then it must have an order to exist as a set. — Metaphysician Undercover
We can say that the order is accidental, it is not an essential feature, so that the same set could change from one order to another, just like the kids in the class, and still maintain its status as the same set. — Metaphysician Undercover
However, we cannot say that a set could have any order by reason of the fallacy described above, because this is to say that it has no actual order which implies that it does not exist. — Metaphysician Undercover
No, I don't see that at all. They are all concepts, ideas. By what principle do you say that mathematical concepts are "objects", but concepts like "justice" are not objects. I mean where is your criteria as to what constitutes a conceptual "object". I know it's not the law of identity. — Metaphysician Undercover
You've never heard "the object of the game"? — Metaphysician Undercover
So in this context, "first" means best. Clearly this is not how "first" is used in mathematics. In mathematics, "first" has a temporal reference of prior to, as I said, not a qualitative reference as "best". — Metaphysician Undercover
Your attempt at equivocation is not very good, I'm happy to say, for your sake. Ask Luke who is the master of equivocation for guidance, if you want to learn. I think you ought to stay away from that though. — Metaphysician Undercover
.The problem obviously, is that you, and mathematicians in general, according to what you said above, haven't got a clue as to what a number is. — Metaphysician Undercover
It's just an imaginary thing which you claim is an object. It appears like you can't even tell me how to distinguish the number 4 from the number 5, because you refuse to recognize the importance of quantity. — Metaphysician Undercover
And if you would recognize that it is by means of quantity that we distinguish 4 from 5, then you would see that "4", and "5" cannot each represent an object, because one represents four objects, and the other five objects. Why do you take numbers for granted?
. — Metaphysician Undercover
Right, and the reason why I argued this is that we ought not have two distinct activities going by the same name in a rigorous logical system, because equivocation is inevitable. So, one ought to be called "counting" and the other something else. I propose the obvious, for the other, expressing an order. — Metaphysician Undercover
The original paper is in Jean van Heijenoorts's 'From Frege To Godel'.
— TonesInDeepFreeze
[,,,] I'm wondering if you could summarize. — fishfry
Did von Neumann anticipate the categorical approach — fishfry
But now you are saying that space and time have "conceptual" meaning; at the same time you deny that 5 or other numbers can have conceptual meaning. — fishfry
How about "inspired by" rather than grounded? As in Moby Dick being a work of fiction nevertheless inspired by a real historical event. Of course we get our concept of number from real, physical things. Nobody's denying that. — fishfry
Well the "first" element of a total order is an element that is less than any other element. Some orders have a first element, such as 1 in the positive integers. Some orders don't. There's no first positive rational number.
That's what first means. — fishfry
Now that's funny, as we got off onto this conversation by pointing out to you that numbers can indicate order as well as quantity. But of course ordinals are different than cardinals. Two distinct ordinals can have the same cardinal. — fishfry
red, blue, green. Three words ordered by length. There is no time involved. You are stuck on this point through stubborness, not rational discourse. The player who finishes first in a golf tournament is the one with the lowest score, NOT the one who races around the course first. — fishfry
I have already given many counterexamples such as rationals, reals, complex numbers, p-adics, hyperreals, and various other exotic classes of numbers studied by mathematicians. What quantity or order does 3+5i3+5i represent?
There is no general definition of number in math. That's kind of a curiosity, and it's kind of an interesting philosophical point, and it's also factually true. — fishfry
I've made my point and all you have is mathematical ignorance. — fishfry
You haven't seen them in the playground at recess. Of course that's only when I was a kid. These days I gather they don't let the kids run around randomly at recess. — fishfry
If you don't know that sets have no inherent order, there is no point in my arguing with your willful mathematical ignorance. — fishfry
No that is not true. It's entirely contrary to the concept of set. A set has no inherent order. An order is a binary relation that's imposed on a given set. If I have a set and don't bother to supply an order relation, then the set has no order. Sets inherently have no order. That's what a set is. You can sit here all day long and make up your own definitions, but that's of no use or interest to anyone. — fishfry
I'm asking you, if you don't accept the phrase mathematical object, what phrase do you use to name or label conceptual entities that are mathematical, as opposed to conceptual entities like justice that are not mathematical? — fishfry
I propose instead that we reserve the term "counting" for counting the natural numbers and counting imaginary things, and that we should use the term "measuring" (instead of "counting") for "determining a quantity". — Luke
I surely have not denied that "5" has conceptual meaning. — Metaphysician Undercover
It doesn't seem to me to be a precursor to category theory, but I don't opine. — TonesInDeepFreeze
If you give the number 2 meaning, a definition, to validate its existence as a conceptual object, you might say that it means a quantity of two, but then you justify my argument, that counting is counting a quantity of objects, — Metaphysician Undercover
If you give the number 2 meaning by saying that it is the number which comes after 1, then you justify my argument that what you are doing is expressing an order, rather than counting. — Metaphysician Undercover
I surely have not denied that "5" has conceptual meaning. To say that the numeral "5", when it is properly used, must refer to five distinct particular things, is to give it conceptual meaning. It is a universal statement, therefore conceptual. I am not saying that it must refer to one specific group of five, as a name of that group, I am saying that it could refer to any group of five, therefore it is a universal, and this indicates that the "5" in my usage refers to a concept, what you've called an abstraction, rather than any particular group of five. — Metaphysician Undercover
For example, if I said that to properly use "square", it must refer to an equilateral rectangle, or "circle" must refer to a plane round figure with a circumference which has each point equidistant from its center point, I give these terms conceptual meaning, because I do not say that the words must refer to a particular figure, I allow them to refer to a class or category of figures. — Metaphysician Undercover
Even if I said that "5" must refer only to one particular group of five, or that "square" must refer only to one particular figure, it could still be argued that this is "conceptual meaning", because to understand this phrase "must refer only to one particular", is to understand something conceptual. In reality any meaning assigned to word usage is conceptual, so this position you've thrust at me, that I deny the conceptual meaning of 5, is nonsense. What I say is that the conceptual meaning given to "5", in some situations, namely that it refers to a type of object called a number (as described by platonic realism), ought to be considered as wrong. Do you accept the fact that concepts can be wrong? For instance, your example of "justice". A group of people could have a wrong idea about what "justice" means. Likewise, a group of people could have a wrong idea about what "5" means. — Metaphysician Undercover
Why would you want to make this change to "inspired" rather than "grounded"? Logic is grounded in true premises, and this is an important aspect of soundness. If your desire is to remove that requirement, and insist that the axioms of mathematics need not be true, they need only to be "inspired", like a work of fiction, the result would be unsound mathematics. Sure this unsound mathematics might be fun to play with for these people whom you call "pure mathematicians", and I call "mathemagicians", but unsound mathematics can't be said to provide acceptable principles for a discipline like physics. — Metaphysician Undercover
OK, I assume that "less than" refers to quantity. — Metaphysician Undercover
So we're right back to my original argument then. Numerals like "1", "2", "3", "4", refer to a quantity of objects, "3' indicating a quantity which is less than that indicated by "4", and "first" indicates a lower quantity. How do you propose to remove the quantitative reference to produce a pure order, not grounded in a physical quantity? — Metaphysician Undercover
If you are grounding your definition of "order" in "less than", as you have, then numbers simply indicate quantity, and your "order" is just implied. It is not the case that "2" indicates "first" in relation to "3" and "4", it is the case that "2" indicates a quantity which is less than the quantity indicated by "3" and by "4". And by your premise, that the "first "is the one which is less than the others, you conclude that "2" is first. — Metaphysician Undercover
Therefore "order" as you have presented it is not indicated by the numbers, only quantity is indicated by the numbers. Order is indicated by something other than the numbers, it's indicated by your premise that the numeral signifying a quantity less than the others, is first. — Metaphysician Undercover
You clearly haven't followed what I've been saying, — Metaphysician Undercover
and I realize that I did not make myself clear at all. — Metaphysician Undercover
The point is that if we remove the reference to a quantity of individual objects, from numerals, then the ordering of numbers requires a spatial or temporal reference. You seemed to believe that we could remove the quantitative reference, and have numbers with their meanings understood in reference to order only. Clearly, "less than" does not provide this for us. And your example of the length of the word here, is a spatial reference. — Metaphysician Undercover
Your other example, of the best score being first is only made relevant through a quantitative interpretation. How is 3 better than 4? Because it's less than. So you have not removed the reference to quantity as the necessary aspect of numerals, to provide a purely ordinal definition. Therefore I am still waiting for you to prove your claims. — Metaphysician Undercover
You have shown me absolutely nothing in the sense of a number not dependent on quantity for its meaning. — Metaphysician Undercover
If your point is that "order" is defined by " less than", and this is supposed to be an order which is independent from quantity, then you've failed miserably at making your point. — Metaphysician Undercover
Obviously, "in the playground" is not "in the classroom", and you're clutching at straws in defense of a lost cause. — Metaphysician Undercover
Instead of addressing my argument you portray me as mathematically ignorant. It's not a matter of ignorance on my part, it's a refusal to accept a mathematical axiom which is clearly false. So I'd correct this to say that this is an instance of your denial, and willful ignorance of the truth, for the sake of supporting a false mathematical axiom. — Metaphysician Undercover
Show me that set which has no order then. — Metaphysician Undercover
And remember, there is a difference between a thing itself, and the description of a thing. Therefore to describe a set which has no order is not to show me a set which has no order. — Metaphysician Undercover
I think you need to make clear what "set" means. — Metaphysician Undercover
Does it refer to a group of things, or does it refer to the category which those things are classed into? — Metaphysician Undercover
The two are completely different. Take your example of "schoolkids" for instance. Does "set" refer to the actual kids, in which case there is necessarily an order which they are in, even if they are running around and changing their order? Or, does "set" refer to the concept, the category "schoolkids", in which case there are no particular individuals being referred to, and no necessary order? Which is it that "set" refers to, the particulars or the universal? Or is "set" just a clusterfuck, a massive category mistake? — Metaphysician Undercover
You just named it for me. "Mathematical" is the word I use to refer to mathematical concepts. In ethics there are ethical concepts like justice, in biology there are biological concepts like evolution, and in physics there are physical concepts like mass. Why do you think mathematics ought to be afforded the luxury of treating their concepts as if they are objects? — Metaphysician Undercover
But the set of natural number may nonetheless be ordered in many alternative ways. — fishfry
But no set has order. That's the axiom of extensionality. Will you kindly engage with this point? — fishfry
So I can use the phrase mathematical, but not mathematical objects? But mathematical is an adjective and mathematical object is a noun. You've still not answered the question.
But are you saying that if I call 5 a "mathematical concept" you're ok with that, but NOT with my calling it a mathematical object? Ok, I can almost live with that. Although to me, it's a mathematical object. — fishfry
I think you need to reread my post. I have no desire to respond to your misinterpretation. — Metaphysician Undercover
If you give the number 2 meaning, a definition, to validate its existence as a conceptual object, you might say that it means a quantity of two, but then you justify my argument, that counting is counting a quantity of objects, and "2" refers to two objects, not one object, the number 2. — Metaphysician Undercover
If you give the number 2 meaning by saying that it is the number which comes after 1, then you justify my argument that what you are doing is expressing an order, rather than counting. — Metaphysician Undercover
You might argue that “counting” in the sense of reciting the natural numbers in ascending order is not the proper meaning of the word, but why is it not? Why is “counting” in the sense of determining a quantity the only proper meaning of the word? These are both counting. — Luke
In a logical proceeding, it is imperative that the symbol employed maintains the same meaning, to avoid the fallacy of equivocation. If "beating" means something different when used to describe beating eggs, from what it means when used to describe beating drums, and we proceed with a logic process, there could be a fallacious conclusion. For example, after the eggs are beaten, the internal parts are all mixed up into a new order, therefore if I beat the drums the internal parts will become all mixed up into a new order. — Metaphysician Undercover
It is my opinion that there is no such thing as numbers which serve as a medium between the numeral (symbol) and its meaning, or what it represents. — Metaphysician Undercover
To say that a particular order is "ascending order", is simply to make a reference to quantity. — Metaphysician Undercover
I welcome you to provide a non-circular reason for why "determining a quantity" is (true) counting and why "reciting the natural numbers in ascending order" is not (true) counting. — Luke
To determine a quantity is equally to make reference to an ascending order. — Luke
I explained this already. Your "ascending order" is based on quantity, therefore your supposed "count" of ascending order means nothing unless it is determining a quantity. — Metaphysician Undercover
This is why "numbers" as objects are assumed, so that when you count up to ten you have counted ten objects, (numbers). — Metaphysician Undercover
And, if numbers are not true objects, as I argue is the case, then this is not a true act of counting at all. — Metaphysician Undercover
