Title: Invalid Inductive Argument
Post by: LogicIsBetter on September 01, 2008, 08:27:20 PM
I've seen this argument many times now:

Everyone can look out their windows and observe a flat earth.

It's basically an inductive argument, if you give credit for repeated observations over time, or repeated observations from many windows.

  The earth looks flat to me from point a.
  The earth looks flat to me from point b.
  etc.
  Therefore, since the earth always looks flat to me, the entire earth must be flat.

While it is possible to prove some things using induction (mostly mathematical proofs) beyond any doubt, applying inductive logic to anything in real life is very difficult.

In this particular case, why should you conclude that the earth is flat across approximately 25,000 miles, when you can never see more than a few miles at a time?

Worse yet, as in planar earth, why should you conclude that the earth extends as a perfect plane in all directions, when not only have you not seen it all, you cannot see it all (if it's truly infinite)?

I say this argument by itself is completely invalid since there is no logical reason to jump from seeing a few miles to concluding the rest of the earth is the same. 
Yet it is usually presented just as the above quote.  Short and concise with no additional support, so I don't think I'm presenting a straw man.

Does anyone have an argument for why this induction should be considered valid?

Title: Re: Invalid Inductive Argument
Post by: LogicIsBetter on September 01, 2008, 08:56:57 PM
did you read the FAQ?

Of course I did.  But this argument is presented by itself in many topics as if it were the end to all arguments, usually by Tom Bishop or narcberry, sometimes by others.

My observation is that FE'rs believe this to really settle something and it's flawed logic.  It shouldn't even be part of the equation.

What are you talking about?  I'm not asking for someone to explain how the earth could appear flat.  I'm pointing out flawed logic in the form of one of their most common arguments.  The post is about the form of the argument, not the content.  (and i've read about the content of the argument plenty, including the bendy light EA stuff).

I wanted to start a debate about the form of logic FE'rs use.  Unsubstantiated assertions (like yours above) are not logic at all.
Do you care to debate my topic or not?  Did you even read it?

so when I look out my window if looks flat so the earth must be flat but then light gets bent up so when I look out my window and it looks round but that is only because light gets bent up to make it appear look like that because the earth is flat?

No it is not a valid logic to use but it is a necessity for their arguments when you look at the substance of their evidence.

Proof
1. A small piece of ground can be perfectly flat.
2. The earth consists of billions of these flat surfaces.
3. The sum of billions of flat surfaces is a giant flat surface.
4. The earth is flat.

Circular logic.

So to confirm you are saying that your statement does not apply to cubes or any other shape with faces equidistant from the centre?

Nice one.

You said the Earth was flat because of this reason.
I want to know if this reasoning applied to other shapes. Can you answer it or not?
It's a simple yes or no.
Title: Re: Invalid Inductive Argument
Post by: FETftw on September 02, 2008, 12:09:07 AM
why wouldnt it apply to other shapes. as long as they are flat, like the earth is, you can look across them. with the exception of the light bending what you can see, what does the diameter matter?
Title: Re: Invalid Inductive Argument
Post by: dyno on September 02, 2008, 12:16:17 AM
Ok, since you are having difficulty grasping your own logic, I'll break it down for you.

A cube is composed of flat surfaces. If you are small enough for the cube is large enough it will appear flat.
There are 6 of these surfaces. All appear flat.
The cube is flat according to you.

Therein lies the problem.

I'm saying your argument was flawed and local observations of the surface can not provide sufficient information to describe the body as a whole.

Respond at your leisure.

we are only talking about the top part - the part where the land and water is.
that part - the visible part - is flat. like the earth. what part of that are you having trouble with?
why oh why would i be worried about all those other surfaces? we dont live on those surfaces, silly.
Title: Re: Invalid Inductive Argument
Post by: dyno on September 02, 2008, 12:35:28 AM
Oh... so the Earth isn't actually flat, just locally flat?

It could be a cube?

What is the shape of the entire Earth?

The logic you used to backup your statement of a FE remains as flawed as it was when you first posted it.
Title: Re: Invalid Inductive Argument
Post by: LogicIsBetter on September 02, 2008, 03:39:59 AM
Proof
1. A small piece of ground can be perfectly flat.
2. The earth consists of billions of these flat surfaces.
3. The sum of billions of flat surfaces is a giant flat surface.
4. The earth is flat.

At least we're getting somewhere.

This is not the argument as it is usually given, as in my original post, but let's just take your form of it then.

1.  Can you please define "small" and "perfectly flat"?
How much variation is allowed for it to be perfectly flat?
How many square miles must it be less than to be considered "small"?

2.  Since you have not observed "billions" of these "small" pieces, this proposition suffers the same faulty inductive leap that I'm questioning.
The whole of this argument is a faulty assumption about the sum of the parts, in fact.

3.  Only if you know they join at 0 degree joints, but to know that you would need a larger view than the "small" flat piece you are considering at any given time.

4.  There is insufficient justification for the conclustion.

I think the point is that a flat Earth may not be the most easily explained conclusion, but it is one possible conclusion that you could draw.  Trying to defeat FET by simply saying that RET is simpler and more widespread will not work here - if you've read around this site you will know this by now.  The way you have to approach it, in my view, is to present evidence and an argument accompanying that evidence and see what the FE guys come up with. You then examine their counter-arguments, again using evidence, and so on and so on.  Eventually either the thread is derailed and serious FE theorists stop posting, which you can claim as a personal victory, or the argument ends up based on untestable ground (conspiracy or conspiracy-based evidence), in which case stalemate ensues.

Anything else will be claimed as a win for FE - just keep your wits about you and debate, and you will be fine.

No. If you add to the proof that any piece of ground is perfectly flat, then the piece of ground consisting of adjacent halves of two other pieces of ground is also perfectly flat, and therefore they must be parallel as well as flat.

How about this. I look out the window at the lighthouse at Byron Bay the Easterly most point of Australia. I have a full 180 degree field of vision that is all ocean. Now if I can see directly east to the horizon, where ships apparently disappear due to the curvature of the earth, then I should be able to see the earth curve away to the north and the south.

But I do not.

Look at this picture. Does this look flat (theoretically)? Of course not! Does it look round? Yes, but it isn't. This 3d model consists of several flat surfaces all angled to make it look round. Don't believe me? Ask any 3d modeler!

Now, I'm seeing people here saying "The Earth is round! Look: RET = Real Earth Theory, FET = Fake Earth Theory", and even more of "Look outside your window, the ground is flat! see?!"

Look, just because you can take any one small part of Earth and call it flat, does not mean the rest of the Earth is flat. Infact, when I look outside my window, there are various hills and stuff. They're not flat, unless you were to cut out the side of one of those hills. My point being, is that the Earth is too big to come up with any conclusions on its shape just by looking out your window. It's like saying that air doesn't exists because you don't see it.

Things aren't exactly as you precieve. FE'ers merely looked out their window, saw a flat patch of ground, and suddenly assumed earth was flat, and made up a bunch of crap to make it seem a little more true.

The only reason the thread is dead is because it went way off topic.  I asked for an analysis of the inductive reasoning in the argument.  It is the same argument as this:

I see one black crow.

That's an invalid argument.  Faulty use of induction.  Failure at universal instantiation.

So then it could look like this?

http://en.wikipedia.org/wiki/Image:Uniform_polyhedron-43-h01.png (http://en.wikipedia.org/wiki/Image:Uniform_polyhedron-43-h01.png)

No. If you add to the proof that any piece of ground is perfectly flat, then the piece of ground consisting of adjacent halves of two other pieces of ground is also perfectly flat, and therefore they must be parallel as well as flat.

So you agree then that the argument as it is usually given is inadequate?

Typical responses from FEs are to state their beliefs and ignore the presented evidence. This thread is dead

The only reason the thread is dead is because it went way off topic.  I asked for an analysis of the inductive reasoning in the argument.  It is the same argument as this:

I see one black crow.
I see two black crows.
I see three black crows.

Therefore all crows are black.

if it looks like a duck, quacks like a duck and waddles like a duck - is it a goose? no silly, its a duck. if its flat when i look out my window, and if i drop a ball and it doesnt roll, guess what - earth is flat.

OK people, here's how it works (once again, this time with feeling):

1) This site is for debate
2) One of the axioms of this debate is that there is a conspiracy preventing use of space-agency evidence as valid
3) The FE model is one of many conceivable geometries for the Earth - to say that any one is more valid than another requires logical debate supported by evidence
4) Lurk moar
5) Don't trust Tom Bishop, he's part of the conspiracy

Saying FE is an invalid theory based on a hole in inductive reasoning is completely pointless - it proves nothing other than you may need another reason for thinking the Earth may be flat, of which there are an infinite number. Stop trying to circumvent the debate and if you're a really dedicated RE'er then grow a spine, get your logic cap on and bloody well prove it.

Well said Matrix.

So explain this.
I say this argument by itself is completely invalid since there is no logical reason to jump from seeing a few miles to concluding the rest of the earth is the same. 
I look out the window at the lighthouse at Byron Bay the Easterly most point of Australia. I have a full 180 degree field of vision that is all ocean. Now if I can see directly east to the horizon, where ships apparently disappear due to the curvature of the earth, then I should be able to see the earth curve away to the north and the south.

But I do not. Does this not demonstrate that the earth is flat?

An appeal to an authority is also a logical fallacy.

http://www.nizkor.org/features/fallacies/appeal-to-authority.html


I quote from your source:

Quote
Description of Appeal to Authority

An Appeal to Authority is a fallacy with the following form:

   1. Person A is (claimed to be) an authority on subject S.
   2. Person A makes claim C about subject S.
   3. Therefore, C is true.

This fallacy is committed when the person in question is not a legitimate authority on the subject. More formally, if person A is not qualified to make reliable claims in subject S, then the argument will be fallacious.

This sort of reasoning is fallacious when the person in question is not an expert. In such cases the reasoning is flawed because the fact that an unqualified person makes a claim does not provide any justification for the claim. The claim could be true, but the fact that an unqualified person made the claim does not provide any rational reason to accept the claim as true.


An appeal to authority is only fallacious when the authority is not legitimate. Appealing to the authority of astronomers when making arguments about astronomy is not a fallacy. Appealing to the authority of a space agency when making arguments about space flight is also not a fallacy - unless you can prove that they have never been to space. Which you can't.

Refer to point 2) above re: space agencies.



Since the conspiracy was always presented as fact, it's no wonder most non-FE'ers - including myself - were unwilling to accept it. I'm fine with axioms as long as they are based on logical and comprehensive assumptions. The problem with the conspiracy theory as presented by FET is that it is neither logical nor comprehensive. It's not even consistent. So far FE'ers have been adapting the conspiracy theory as they see fit in order to support their particular argument - sometimes the governments of the world are involved, sometimes they are not, etc. depending on what the FE'er in question is trying to prove.

Before I accept the conspiracy as an axiom for this debate, I would like to see the Flat Earth Society agree on an outline for it, especially concerning the involved governments, corporations and societies, and above all: the motivation behind the conspiracy.

If the FES can provide a consistent and comprehensive reference for this conspiracy theory, I have no problem accepting it as an axiom.

I didn't say the theory was invalid; I said that particular argument was invalid.  I'm perfectly aware that there are other arguments.  You seem to think debate doesn't require the use of logic.  If you can't use logic correctly, then there is no way to debate.  Period.  And if we can't debate the use of logic by FE and RE, then how can you ever determine who wins the arguments?

And if we knock down one FET argument after another because it is not a valid argument, then FET becomes a weaker theory.

And don't tell me to put on my logic cap.  That's what this thread is about.  I understand logic.  Very few of the FE defenders seem to, however.  I also understand debate.  Debates can be won by supporting your own position, undermining your opponents position, or a combination of both.

If you can't defend an argument, then abandon it or improve it.  That's the point of this thread, which I think is in line with the point of this site.

A logical debate is not one that should be conducted with the aim of one side 'winning' so much as all those debating get a little closer to the truth by agreeing on the best solution to the given arguments. True, if someone holds very entrenched beliefs it may be impossible to move them from their position, in which case you have to hope that everyone else who joins in/reads the debate will form their own opinion and not be drawn into school playground-style 'picking sides'. You have to go in with an open mind, and being dead set on 'winning' is certainly not going to help your objectivity.

And if we knock down one FET argument after another because it is not a valid argument, then FET becomes a weaker theory.

So as I said, go and debate in the other threads - make your arguments and present the evidence. Debate. Enjoy. That's the whole point.

I would say the point of this site is to debate the idea of a flat Earth.  Given that space agencies have provided convincing evidence that the Earth is flat (via orbital photography etc), the one assumption you have to make to discuss a flat Earth is that such evidence is fake. If you are not willing to work within that assumption then there is no point in discussing the FET.

I understand your position, but do you think people should form their opinions on, or be swayed by, faulty logical arguments? 

Maybe you have a different idea of what logic is.  Logic is not the same as debate.  A debate may only sway opinions, and some tactics in debate may be considered fair or unfair, but logic, at least as I've studied it, is rather formal and requires proper use of logical rules.  A logical argument can be valid or invalid, sound or unsound.  It has to be both sound and valid to be useful.  Otherwise it's nothing but a deception. 

Are you saying this site is only for arguing and the logic used can't be called into question?  If so, then that's not very interesting.

I have a BS degree in Math and Philosophy with an emphasis in logical theory.  I'll be glad to debate the evidence and find new ways to defend either theory, but if I can't call you on a bad argument, then all that remains is unsubstantiated assertions and finger pointing.  And there's no shortage of that here already.

I also appreciate what you're trying to say, and I have a fair understanding of logic (not in terms of having studied logic in itself, but it comes in handy in a PhD in Experimental Quantum Optics as a tool for problem solving).  The key point I am making is this: let's say you take issue with the idea of the conspiracy (which has to exist in order to make the FET compatible with NASA photography/photoshopography).  Fair enough, it's not exactly the result of following Occam's razor to it's logical conclusion after all. Logic and reason must then be applied to any debate to ensure that it remains soluble, although some of the issues with the conspiracy are by their very nature unprovable (unless some NASA employee went nuts and started posting 'the truth' on here, at any rate), which limits how far logic can be applied.

When you are faced, in the end, with trying to logically disprove a conspiracy then logic can begin to work against you.  Surely whoever the architect of the conspiracy is will have sewn misinformation throughout the history of the deception in order to cover their tracks... the odds of avoiding at least some of that during the course of a logical debate of the available evidence is vanishingly small, rendering any conclusions drawn to be suspect.

I guess what I'm trying to say is that you need to treat FET as a scientific theory that makes predictions on the observable Universe.  If you take my approach you then examine those predictions and show them either to be compatible with RET and/or evidence, or not. FET will often then be modified to encompass the new data, which is fine - the Standard Model of Particle Physics has dozens of free parameters that can be squeezed this way and that to fit new data as it emerges, but that doesn't stop it being our best description of quantum mechanics and all of nature's forces (other than gravitation). Ultimately, FET has to be judged based on its scientific merits, which excludes the conspiracy.  I came to that conclusion a long time ago, and if you want to stay sane around here then you may well have to do the same.

Good luck to you otherwise! I will follow your debates with interest!

Thanks for the response.  The clever thing about conspiracy theories (which I love to explore) is that any supposed disproof of them is only further fuel for the fire, since it may just be further obfuscation from the conspirators.  Sort of like a dog chasing its own tail.

I certainly find the scientific aspects of this interesting.  It just goes to show that you can have different interpretations of the same data and carry if quite far if you're willing.  It reminds me very much of Immanuel Kant.  How can you really know anything based on your senses anyway?  If they are untrustworthy, you will never know it via the senses themselves.

BTW, you can see the whole duck.

Can you see the whole earth?

When I look out my window I see everything which suggests a Flat Earth and nothing which suggests a round one.

Saying that the earth looks flat from where youre standing doesnt make the entire thing flat. using the same logic:
Where I am, birds fly south for the winter because its warmer there. I used to live in Britain, and the birds there would also fly south for the winter, because its warmer there. Therefore, its always warmer in the south.

That is obviously poor logic because to come to the conclusion you cant just use the example of a few places, you have to go everywhere on earth and survey it all, then make a model for it all, showing that no matter where you are, its warmer in the south, or the earth is flat or whatever.

I bet some stupid FE'r who doesn't understand logic and reasoning will respond to this "but Nobody has the resources to do all that, so your argument has no evidence. another victory for FE!"

so what you just deduced makes you smarter than "some stupid FE'r"?
when you make your trip - report back to us and let us know how it went, since you obviously have no proof  of your theory.
another win for FE!

LOL... yes a minor typo on my part.  I also would like to know what orbital space flight being impossible has to do with either my post or maddog's reply...
Well since orbital space flight is not possible with my impossible Flat Earth Theory, it is not possible to have orbital photography, therefore this must prove the earth to be flat.

No, and I've banned that person. Their only other post was pointless spam, too.

Good good, thought I was going mad for a minute there...

As an aside, I wonder how many more posts on gravity there are going to be... my guess would be they'll keep coming until every last electron in the Universe is being used to store threads on it.

Alright let me take a stab at this
Proof:
1. The earth is perceived round from outside of its atmosphere
2.  The earth is perceived flat from inside of its atmosphere
3. Proof 1 and 2 are inevitably true, and rejected by only those that are delusional
4. We cannot reject what we perceive, but what is reality can differ from what we perceive
5. If we perceived, from outside of the atmosphere, a single entity scaling the earth then his pattern of movement would be circular
6. if we perceived, from within the earths atmosphere, a single entity scaling the earth, then his pattern of movement would be straight
7. our perception in this way is relative because it varies from different vantage points
8. Its impossible to walk straight and return where you started
9. If you walk straight and return where you started it it only because it was unobvious through your current perception that your pattern of movement was that of along of a very vast "spherical"
10. Moving "forward" is more accurate dealing with perception
11. Thus, we have 2 perspectives of the earth, however there is one reality, The earth is round; the word "straight" is a fallacy in this perception; and moving "forward" is more appropiate

'1. The earth is perceived round from outside of its atmosphere'

There is absolutely no proof of this, none. Lens distortion proves nothing. You are trying to use a false positive in our logic which negates the whole thing.
