quote:quote: How is that not an object? How is the relationship between two objects not also something that exists?
quote:quote: Not even the fact that there are five of them?
quote: So? What does the fact that you need the group of them have to do with anything? Plurality is a property of multiple objects. Each finger by itself is only one.
quote:quote: Your body is going to decompose that quickly? You planning on diving into a vat of acid as your means of demise?
quote: So? You don't have five fingers on your hand?
quote: No, the null set is a set, too, but you're talking about the original set. That said, so? Are you saying you don't have five fingers on your hand?

quote: -------------------------------------------------------------------------------- Yes, I do see 5 fingers when I look at my hand, but I don't accept this as evidence that 'fiveness' exists anywhere except in people's minds... -------------------------------------------------------------------------------- Would the number of fingers on your hand change if nobody was around to count them? Well, if nobody were around to count, there would be no concept of number, and therefore - it seems to me - impossible to know whether there were such thing as number.I am quite happy with the idea that sets exist as objects in people's heads, but when you say that numbers or sets exist as objects, I get the impression that you mean that they have an existence independent of people. How? Where? Of course, I'm in no position to prove that there isn't, for example, an empty set of five elephants on my computer table, and I am well aware that the view that there can be is a widely held and impeccably respectable philosophical position, but it puzzles me. It seems to be a view that is useful for mathematical purposes but unsupported by any (any possible?) empirical proof. I regard that as a serious objection. What do you think?

It can be argued that you are just a set of objects. The you of your youth is gone in more ways than one.
Most if not all of the atoms of your body that were there when you were 10 have all been changed. There is no physical you left. Then what are "you"? Just the organization of something. Just a set defined by some boundaries.

How is the relationship between two objects not also something that exists? Here's two apples. Point to their relationship. Better yet - here's two apples, only one of them is here and the other is in Sweden. Now point to their relationship.
Not even the fact that there are five of them? The set of fingers has five. The fingers themselves don't. How many times do I have to say it?
So you don't have five fingers on your hand? No, I'm saying that when I count them, there's five. When I'm not counting them it's meaningless to say how many fingers there are. You're really putting words in my mouth, here, and it's starting to seem like you're playing games instead of supporting the assumptions that allow you to assume that numbers have an existence beyond our conception of them. I want to know what's so special about numbers that doesn't apply to Monopoly.

You are perfectly welcome to think of me as a set of objects, NosyNed . Perhaps perceptions of people can only exist in each other's minds in that format. But can you find any way to demonstrate which, if either, of these 2 views is correct -
-The thing we can call the "set of me" really is inherent in me, whatever my opinion. -The things that are me just exist. The idea that they are a set is a useful construct that has no necessary existence in its own right. Plainly both views exist. Discussions of this sort usually seem to end in deadlock - "You're a set" "No I'm not". But if you think I am a set, what grounds do you have for treating that as a fact rather than a belief? If it is an undecidable question, in the sense that it is not publically verifiable, it looks more like a belief to me. [This message has been edited by Chavalon, 05-24-2003]

The point is that we can't be considered to be something specifically physical. Whatever "we" are it isn't the precise atoms that make us up. It is the arrangement of some atoms. So it is the arragnement that is important not the exact physical things which are arranged.

OK, replace the words 'object' and 'thing' in my previous post with 'pattern' or 'arrangement'.
Can you show that there are sets inhering in those patterns, rather than just in your view of them? [This message has been edited by Chavalon, 05-24-2003]

quote: A positive times a positive is a positive. A negative times a negative is a negative. i requires that a negative times a negative is a negative or that a positive times a positive is a negative.
quote: I didn't say that mathematical operators within the complex number system would be the same as within the real number system. What I said is that [/i]i[/i] itself is a problematic number, as exlained above. You've got one system with a contradictory number, or two systems incompatible with one another. The 'bridge' between the two is a number that can't exist in one system. Either way, the point is the same, there are holes in mathematics. It isn't complete. It isn't absolute.
quote: Yeah, I know that. And, as you say...
quote: Fine. Why are you avoiding the question? When you refer to geometry and mathematics and logic, are you not talking about systems sophisticated enough that the incompleteness theorems apply? In other words, the logic and mathematics which you have made out to be absolute and infallible are the very things which get screwed by Godel's proof.
quote: More whining... Sorry. I assumed you knew what you were talking about.
quote: The argument itself is true, else it would be a silly argument. You are talking about the right side of the if/then statement-- the conclusion. I am talking about the truth value of the whole statement, or the whole argument.
quote: Why are you changing the rules to suit yourself?
quote: You need to dig yourself out of math and into the real world.
quote: Because we made up the rules. The universe is not bound by our rules.
quote: Yes, in an absolute sense. You can always assume a starting point and go from there, which is exactly what we do. There is no other choice. But it is dishonest to make absolute statements when there are assumptions at the foundation.
quote: You just don't listen do you? I give you definition I used and you still don't get it? This is getting to be ridiculous. Half your argument has come to special pleading for your preferred definition.
quote: Jesus Christ!!! I rephrased the damn question for you!!!
So you agree that if there is a largest prime then our system of mathematics is contradictory? That was the question. How could you miss that? BTW, there is a little button right at the botom of the message that will take you back to all the context you could want.
quote: Do I have proof that this statement is true? Yes, and you know what that proof would be, or you wouldn't have agreed that the statement is true. Do I have proof that there is a largest prime and thus mathematics is contradictory? Do I have proof that any number exists? Nope. Kind-of a silly question really. We made them up to record quantities. They are mnemonics. But what does it matter? The point is that your 'absolutes' are conditional upon our understanding of mathematics.
quote: And? That still leaves the parts that cannot be decided. And you've already equated 'incomplete' and 'inconsistent.' Looks like you've cut your own throat.
quote: Can we stop playing games here? When I say 'math' do you think I mean some minimal system like Presburger arithmatic which only models addition? Or do you think I mean the mathematics kids are taught in grade school, high school and college? Why are you trying to wiggle around this by continually referencings some interesting but virtually non-functional mathmatical system?
quote: Until you leave the abstract you haven't really proven anything. Why do you think physicists look for observational evidence to support what has been proven in theory?
quote: Read you statement carefully and think 'generalization from the specific to the universal.' I could't have said it more plainly. Thanks.
quote: I am aware that many mathematicians share your belief. For the vast majority of people on Earth, God-- of some variety-- is real. Is that adequate reason for the belief?
quote: Don't know. If I have no sensory input of, or from, my fingers, I can't really say what they are doing or how many they are. I assume they stay the same, but I know that is assumption.
quote: Precisely where did I say I believe that by thinking really really hard I can change the number of fingers on my hand? This is pitiful, Rhhain.
quote: This little mantra is becoming very tiresome. You seem to pull it out when you don't have an response. Sad... Now....
quote: ( Copy your part ) Just because observation is consistent with prediction doesn't mean ( add my part ) contrary or variant theories are false. Why is that so hard to put together? And why is it so hard to answer?
quote: BS. You are back-pedaling. Look at the context. My post # 53:
[qs]Same with circles, same with triangles. And we end up with something we call geometry. It is the generalization from specific cases to the universal and as such will always be questionable.[/b][/quote] To which you respond in post # 64:
I hate to break it to you, but there was this guy named Euclid and he collected the works of other mathematicians, as well as coming up with some work on his own, and came up with an axiomatic system of geometry by which circles, triangles, and squares were not a "generalization from the specific to the universal" but rather were definitions. You respond to my analysis of the creation of geometry by saying that Euclid made up definitions. What does this tell me? Hint: You consider Euclid's work to be analogous with but contrary to my analysis. You consider Euclid's systematizing geometry to somehow negate the source of those axioms-- the experience of countless forgotten engineers stretching deep into the past. Despite the rant, you don't actually touch the issue. The point has been quoted above, but perhaps I should restate? The axioms did not come from nowhere. Euclid, and whomever he drew from, simplified known geometric figures into axioms-- into abstractions. This is why he constructed Euclidian geometry, instead of some other geometry. And this is why no one questioned these axioms for centuries. Plane geometry is blatantly obvious to someone living on a 'flat' surface, building square houses, etc.
quote: Don't be a child.
quote: Mathematically, but we were talking about a singularity in the real world. The universe appears to be jump-y. This is the essense of quantum theory. The world doesn't follow this mathematical law. Care to try again?
quote: Now you just being stubborn. Did you miss the part where I explained that...
[qs]If you gave some and I missed them, sorry. I certainly didn't do it on purpose. More likely, you made some statement or statements which you feel qualify as the examples I am looking for, but which don't look that way to me to the point that I don't even know which ones it is to which you refer.[/b][/quote] Grow up.
quote: Equivocation. This is absurd. Two grids of squares with numbers in them. Compare them. If the numbers match up, the two squares are the same. Don't pretend this proves the principle of identity. It is an application of that principle.
quote: So much for a straight answer. Lets see if we can't construct what you won't state plainly. "The various geometries taken individually are internally consistent." Fine. Taken individually, they are also inadequate. Each is very limited in scope, applying as each does to a particular type of surface. They are also mutually incompatible and there is no bridge between them, which there must be if we are to get a complete description of the real world, or even a complete ( colloquial ) abstract geometry for that matter.
quote: How do you know that everything must behave logically? This is nothing but 'I can't imagine it to be different.' Incredulity at its finest.
quote: Certainly. And it is horribly ill-named. I found the following definition:
Chaos is the study of deterministic systems that are so sensitive to measurement that their output appears random.
No webpage found at provided URL: http://www.gweep.net/~rocko/sufficiency/node10.html In other words, chaos theory deals with systems so complex they appear random. It is the search for pattern in apparent chaos. It doesn't follow that what appears chaotic actually has a pattern. We won't know that until a pattern is found.
quote: In the dream world of mathematics where you get to make up all the rules, you might be able to do this. The real world doesn't have to cooperate. Why can you not see this?
quote: I didn't say it was an axiom. Pay attention. It is a conclusion-- more of an observation really-- based on experience. Axioms are/were generalized from this experience. Think science. You make a bunch of observations and generalize to a rule or a mechanism-- an 'axiom.' The same process underlies the origin of mathematics.
quote: Because I don't see 'five.' I see five fingers. I see four books. I don't see 'four.'
quote: Your color analogy is ridiculous. 'Red' can be analyzed in several different ways. It has measurable properties-- like wavelength, energy, etc. 'Five' has none of those measurable properties. Build a pure 'raw number' detector then get back to me. Pass 'five' through a detector and give me a mass, frequency, particle size-- something. ------------------

quote:quote: Well, if nobody were around to see, there would be no concept of color, and therefore - it seems to you - imposssible to know whether there were such a thing as color. That's the question: If everybody were blind, would there still be color? Suppose everybody were to die right now, would your car no longer be the color that it is?
quote: Um, you do realize you just contradicted yourself. If it is an empty set, then it has no members and cannot have five of anything.
quote: I think that it is amazing that you can look at the five fingers on your hand and not recognize that there are five of them. ------------------Rrhain WWJD? JWRTFM!

crashfrog responds to me:
quote:quote: There's two of them, aren't there?
quote:quote: Until you can remember that I understand that each individual finger is only one. But the five of them together are five. Are you saying you don't have five fingers on your hand?
quote:quote: So when you're not paying attention, there is some other number of fingers? If everyone were to die right now leaving nobody to count them, the number of fingers on your hand might change? If there were no people to see, would there be no such thing as color?
quote: So when you're not looking at something, it is meaningless to say what color it is? Things only have meaning when you're paying attention to them? You seem to be heading toward solipsism. Are you saying it's meaningless to talk about whether a tree falling in the forest with nobody around to hear it since the forest is meaningless with nobody around to recognize it let alone the tree and whether or not it makes a sound.
quote: But it isn't an assumption on my part. It's an observation. I look down at my hand and I see five. I am of the opinion that it doesn't matter if I'm looking at my hand or not...it contains the same number of fingers. The forest exists and if a tree falls with nobody around to notice it, it still makes a sound.
quote: How does one play Monopoly with no players? You cannot get the rules of Monopoly simply from the set. You have to impose the rules on the set. Your hand has five fingers no matter if somebody looks at them or not. They behave as five no matter what you do. Nobody makes them five, they simply are that way. Or do you not have five fingers on your hand? ------------------Rrhain WWJD? JWRTFM!

Are you saying you don't have five fingers on your hand? No, I'm not saying that. It really looks like you aren't paying attention to what I'm saying because you keep asking that. Is this your argument style? Ask the same inane question over and over again? Just curious.
But it isn't an assumption on my part. It's an observation. How could you possibly make an observation that would support the statement "numbers exist beyond our conception of them?" Any such observation you make only supports the proposition "numbers exist when I count things."
I am of the opinion that it doesn't matter if I'm looking at my hand or not...it contains the same number of fingers. Sure, your opinion. That's fine. My opinion is that your opinion is wrong. See where that gets us?
How does one play Monopoly with no players? You cannot get the rules of Monopoly simply from the set. How does one do math with no mathematicians? Anyway, the rules of Monopoly come with the box. I don't understand your objection.
They behave as five no matter what you do. Nobody makes them five, they simply are that way. They're that way because we invented a number five to come between number four and number six, which we also invented. I'm not really impressed.

John responds to me:
quote:quote: Ahem. What makes you think i is positive or negative? I asked you this once before. You don't understand the rules of multiplication. Indeed, a positive Natural number times a positive Natural number is another positive Natural number and a negative Natural number times a negative Natural number is a positive Natural number while a positive Natural number times a negative Natural number is a negative Natural number. But what about 0? 0 is not a Natural number. Ah...that's right...0 is neither positive nor negative. It isn't a Natural number but rather a Whole number. That's why we refer to "non-positive" numbers when we want to include the negative numbers and 0. So what makes you think i is positive? What makes you think i is negative? It is neither. In the Complex number system, there isn't such a clear concept of "positive" and "negative" as there is in the Reals. Is -3 + 4i positive or negative? How about 3 - 4i? All Complex numbers are written in the form of a + bi where a and b are Reals. It isn't "-i" so much as it is "0 - 1i." Real numbers are a line. Complex numbers are a plane. There are even numbers systems that go one further, creating four roots of -1.
quote: Only in axiomatic number systems sophisticated enough to model arithmetic. Not all mathematical systems fit that description. And evan among those that do, that doesn't mean everything is nebulous. The true statements that are generated in incomplete systems are still true.
quote:quote: Because the question is nonsense. You are asking me to describe the color of a smell.
quote: Um, you do realize that you just tried to equate a field of study within mathematics with all of mathematics, yes? Once again, Pressburger arithmetic is complete and consistent.
quote: Incorrect. Godel's proofs only apply to axiomatic number systems powerful enough to model arithmetic. Not everything in mathematics is that powerful. How many times do I have to remind you of this? Pressburger arithmetic is complete and consistent.

You are asking me to describe the color of a smell. For no other reason than off-topic pique I thought I'd point out the condition "synthenesia" where people do experience the smells of colors, the sounds of numbers, and all kinds of sensory input that appears nonsensical to us. There's some thought that such a condition could be technologically induced in a brain so that sensory data like smell or touch could be transmitted through conventional means (ala television), encoded into auditory or visual data. I find it fascinating, personally.

crashfrog responds to me:
quote:quote: Then why do you keep denying that the group of fingers on your hand don't have the quality of "five"?
quote: That's because as we agreed at the very beginning of this conversation, we have very different ways of looking at the world. I literally cannot understand how it is you can look at your hand and not see five fingers just as you see them as a mottled shade of various intensities of brown. You recognize the color, but you don't recognize the number...even though you're looking right at it and can count it and everything. I don't understand how you can do that. It seems, as I said to John, as if you're saying, "Yes, I'm seeing 'red,' but I'm not sensing 'red.'" How can you look at something and see it and still claim it isn't there? I don't understand how that works. If the number of fingers isn't really there but is simply a figment of your imagination, then that must mean that you don't really have five fingers on your hand.
quote: When a question doesn't get answered, yes.
quote:quote: Because the universe exists. Unless we're going to devolve into Cartesian Doubt and Solipsism....
quote: But they also exist when I don't count them. Or are you saying the universe doesn't exist if we're not paying attention?
quote:quote: Exactly where we are. I can't explain it to you and you can't explain it to me.
quote:quote: By existence. Mathematics happens despite mathematicians, not because of them. Or are you saying that things don't exist?
quote: You have to read the rules before you can actually play the game. There is nothing saying you have to play the game described in the rules with the Monopoly set simply because you have a Monopoly set. In fact, there is a game company called something like "Really Cheap Games" or some such that is of the opinion that if you're the typical person who has bought board games over the years, you've bought the same thing over and over and over...some tokens, some dice, some money. So rather than make you buy all this stuff yet again, they're just going to give you the rules and you can grab everything from that other board game. The mere existence of the Monopoly set does not tell you how to play Monopoly. But the mere existence of objects brings along with them their mathematical properties.
quote:quote: So you're saying you have something other than five fingers on your hand? See, we keep coming back to this question because I literally cannot understand how you can separate the fiveness of five fingers from the five fingers. I don't understand how you can look at five fingers and say that there are five fingers but that it is merely a convention that there are five. That makes me think that it is possible that there is some other number there. If "five" isn't a real thing, then a group of "five" things isn't actually "five" but could be something else if we were to just think about it differently...that you could really hit the barn, the tree, the barrel, the window, the car, and the well with five apples because "five" is just a convention and the "six" targets are just a convention, too, and if you just think about it hard enough, you can turn that "five" into "six." ------------------Rrhain WWJD?

Then why do you keep denying that the group of fingers on your hand don't have the quality of "five"? Because there's a difference between counting something and arriving at the number five, and those objects themselves posessing any kind of self-sufficient "five-ness" that exists beyond socially agreed-upon models of mathematics.
How can you look at something and see it and still claim it isn't there? Because I'm not "seeing" five, I'm assigning five, based upon rules that I agreed to when I decided to use numbers. The rules themselves are simply convention, not some inherent property of the universe.
Because the universe exists. Granted, but that's something that must be assumed, not proven. Any statements about inherent properties of the universe or objects are assumptions inferred by generalizing from specific cases. As of yet, you have not demonstrated why it is fruitful or logical to assume that objects have an inherent property of "number". At least, you haven't done so with any rationale that couldn't also be applied to Monopoly.
But they also exist when I don't count them. See, that's your assumption again. The universe exists. We both assume that. But why assume the same is true for numbers but not for Monopoly?
By existence. Mathematics happens despite mathematicians, not because of them. I don't even begin to see how that answers my questions, much less makes any kind of sense.
You have to read the rules before you can actually play the game. You have to know math before you can do math. So what? You have to know the numbers before you can count with them. Or your society has to invent them. Not every society invents numbers.
In fact, there is a game company called something like "Really Cheap Games" or some such that is of the opinion that if you're the typical person who has bought board games over the years, you've bought the same thing over and over and over...some tokens, some dice, some money. So rather than make you buy all this stuff yet again, they're just going to give you the rules and you can grab everything from that other board game. Cheapass Games. I'm a fan. But that doesn't have anything to do with Monopoly. When you play Monopoly, you're using the Monopoly rules. It doesn't matter what physical objects you use to keep track of the game state. (That's the point of the Cheapass Games concept.) But the fact that the game state may be independant of the physical objects you use to keep track of it doesn't mean that the game Monopoly has some existence beyond the rules we agree on as a society. It's still just a made-up conceptual frame, like mathematics. Nowhere near as useful (personally I hate playing Monopoly), I'll grant you that. But no more made-up, either.
But the mere existence of objects brings along with them their mathematical properties. This is again your basic assumption.
See, we keep coming back to this question because I literally cannot understand how you can separate the fiveness of five fingers from the five fingers. I'm not trying to do that. I'm trying to separate numberness from fingers (or any objects) in general. There's just no reason to assume that numberness is an inherent property of objects. It is a property of sets or groups of objects, but there's no real reason to grant that set or group independant existence either. At the end of the day, objects are objects. They have inherent properties, but numberness isn't one of them. That's a property of relationships between objects, but relationships aren't really real.
