# Do Numbers exist?

 Posts: 5,987 Add as FriendChallenge to a DebateSend a Message 4/21/2016 5:27:52 AMPosted: 6 months agoPlato conjectured that Numbers existed. That they were abstract objects. Archetype like. That they were the paint brush and ruler of the creator.As an Abstract entity, one may say that Numbers exist in the mind only. And therefore are "subjective": dependent on a mind. If this is the case that would make such equations like 2+2 =4 a subjective statement.And yet even if the Numbers are indeed subjective, I don't know anyone who would argue that the equation is false, or untrue.I haven't met anyone who would claim because the Numbers and the equations are mind dependent then they are "relative", practically meaningless.((Side note Plato was 430 BC and so much ahead of his time. When I re read his ideas on numbers I could not help but imagine the universe as a computer program, and the forms he spoke of were like Classes in Object Oriented Programming. And all we see are instantiations of these forms as objects (ha pun objects in OOP and objects in real life))

The first is nnailing down what 'number' means'- the other is nailing down what 'exists' means!With the natural numbers 1,2,3....etc we can say that 3 is what a collection of 3 dogs, 3 wide men and the sides of triangle have in common. But does something that is the common feature of such sets 'exist' in the same way a table or chair exists? I am not sure '3' exists in way a paticular table or chair does, so do we stretch the meaning of 'exists' so it includes 'table and chair' sort of existence and the '3' sort of existence, or exclude 3 from the 'things that exist' club?And if its not bad enough with the natural numbers, others worse when we consider zero, negative numbers, real numbers, complex numbers, transfinite numbers..

Does 'round' exist?It doesn't make sense to sat the objects are round but round doesn't exist. Natural numbers as descriptors must exist becuase how can we discern a characteristic if it doesn't exist.But numbers include entities that don't describe concrete objects we can hold in space. Yet they have properties. Properties that dictate how they interact with other numbers and the result of these interaction reliably predict functions of concrete objects. Such as equations in chaos theory or pertubations that utilize imagionary numbers. Or pi an irrational number that reliably describe spheres (that are concrete holdable objects).If something is non-existent it has no properties. Numbers have properties therefore it follows they exist.

And there is something to what we go by like 10"s so to speak and there has been societies that go by a different system. In a case like that maybe it"s abstract.But if you look at it in something like physics amounts of something effect something else whereas a different amount of something would not, or at least not the same effect. that would be reality and not an abstract.It seems amounts are what they are but the unit of measure of that amount is on us.

Every shape has a cofg, but you can't buy a pound of cofgs - not even on e-bay.If you are doing something with a shape-such as balancing it on the point if a pencil - it's much easier to deal with a single cofg than with gravity acting on each individual atom separately, but does a cofg exist or is it a convenient fiction for calculation purposes?Numbers could be like cofgs, of dubious actual existence but too useful to do without.

However modulo 2 is essentially binary and would only have the symbols 0 and 1 - the symbol 2 would have no meaning.Not that it affects the gist of what you said- I'm just being pedantic.

 Posts: 1,579 Add as FriendChallenge to a DebateSend a Message 4/22/2016 7:16:42 PMPosted: 6 months agoMathematical truths are relative to the system...That is not surprising if the different systems are defined to have different truths. Mod 2 arithmetic is defined so 1+1 is 0, which is not true in regular arithmetic but that was the point of inventing mod 2 arithmetic...The non relative mathematical truth is 1+1 mod 2 is 0.A similar example is working in bases. 17(decimal) labels a point on the number line that has the same properties whether it is labeled 17 or 11(hex) or 21(octal). That number or poimt on the number line) is prime regardless of the base used to represent it.So i would say that mathematical truths are not ',relative' if they are properly specified, such by including which 'mod' or base it refers to.

But 1/3 of a finite thing, the food "a pie", isn't the same thing as the fraction 1/3 is in math. 1/ 3 in math is merely a way of expressing an equation where as 1/3 of a pie is addressing how a finite thing has been equally divided and 1 represents the 1 out of the 3 equal pieces made. It wasn't a mathematical equation being applied to a pie. If it were the exact same expression there would have to still be some pie left because 1/3 expressed mathematically has no "end" solution, therefore leaving food on the plate....lol if that's what you are saying then disregard of course.It would be an equivocation fallacy to say that 1/3 of a "food product (pie)" is defined the same way as the fraction 1/3, because they aren't the exact same thing.

I wonder...What is it that has the properties of being like a horse but with a single long horn on its forehead? Unicorns do not exist yet we can say what properties apply to them and which don't. Sherlock Holmes has the property of living at 221b baker street. He does not have property of lining at 10 downing Street.... I think I need convincing that having properties is a,sufficient guarantee of existence.

And it repeats. But in another base, say base 3.. 1/3 is .1Pi doesn't repeat. It's decimal is a never ending random distribution. No matter what base. It's also a transcendental number. The sum of infinite series also result in pi.Because it repeats with no discernible pattern ((out to I think 10,000 so far I think)) it can't be measured out. You can't mark it off with a ruler. Or cut a piece of wire to that length.And pi is not the only transcendental irrational number sqrt(2) is also one.

In base 10, pi is 3.14... it is a different irrational number in other basesBut how can we say that pi exists in the real world? We cannot find anything in the physical world that is a perfect, ideal, Euclidean circle.What about a perfect right angle triangle, in which the hypotenuse is square root of 2.

In base 10, pi is 3.14... it is a different irrational number in other basesyea but isn't it just an abstract expression of an true amount? that if written, though no one known has exhausted it, it's still a measured amount. the decimal representation of 1/3 goes pretty far or 2/3 for that matter. but a third of a pie is a physical third of a pie.I'm not sure I understand what you mean here dp. But 1/3 of a finite thing, the food "a pie", isn't the same thing as the fraction 1/3 is in math. 1/ 3 in math is merely a way of expressing an equation where as 1/3 of a pie is addressing how a finite thing has been equally divided and 1 represents the 1 out of the 3 equal pieces made. It wasn't a mathematical equation being applied to a pie. If it were the exact same expression there would have to still be some pie left because 1/3 expressed mathematically has no "end" solution, therefore leaving food on the plate....lol if that's what you are saying then disregard of course.It would be an equivocation fallacy to say that 1/3 of a "food product (pie)" is defined the same way as the fraction 1/3, because they aren't the exact same thing.I disagree.1/3 is the amount of a finite objects. For a long time people thought that numbers were a 1 to 1 analog to real objects. And they held a conjecture that Every number or entity could be expressed by a ratio. that is to say a fraction.As mathematical techniques increased, especially after the 1800's it was confirmed that there were some numbers that could never be expressed as a ratio.1/3 is a real and finite amount. The .3 repetition of it is because the base 10 system. 3 does not evenly multiply to 10.But the fraction is not infinite. And in bases that 3 does evenly multiply to, they have non repeating decimals of 1/3

Considering the realm of forms as real is what defines platonism.

Or 1/2 base 2*pi, and so on.

Name a system where there are 2 numbers that have no comparison that can be made between them. I'm lost.....1/3 is a real and finite amount. The .3 repetition of it is because the base 10 system. 3 does not evenly multiply to 10.So what base does it not repeat and in that base does 1/3 represent an equation reduced to simple expression or does it merely explain the dividing of separate numbers that aren't compared to each other?But the fraction is not infinite. And in bases that 3 does evenly multiply to, they have non repeating decimals of 1/3....3 evenly multiply into what? What's the relationship in this base between 1 and 3?
