"What do you mean that in the RE theory we can't trust our eyes?"
I mean the following:
(1) I look outside (or around if I am already outside) and see the flat Earth. It is not round. It is flat. I see it flat, therefore it is flat.
(2) the RE guys explain that it is but an illusion and the Earth is actually round. I see it flat, but the Earth is round. What I see is some kind of illusion, because of ... blah blah blah. So, my eyes are deceiving me. I should not trust my eyes when I see that the Earth is flat.
(3) This is the first and very fundamental step for accepting the RE theory. Either you trust your eyes - and the Earth is flat, or you do not - and the Earth is not flat. Thus, without admitting that your senses are deceiving you (and, therefore, giving away your right and freedom of making your own conclusions), you can not accept the RE theory.
(4) What's truly funny is that AFTER you admitted that your you should not trust your EYES, the RE guys are showing you PICTURES, PHOTOS, MOVIES etc. supporting their theory. But you are already not supposed to believe your eyes. You know that your eyes deceive you and you accepted it as an axiom, otherwise you would not become a RE-er. What if all those pictures are also some kind of illusion? Why you should believe them?
"that makes objects look as if they "disappear" over the horizon,"
If I am not mistaken, they call it "refraction" and, in RE theory, use for explanation why we see the Sun rising earlier and setting later than it should do according to the calculations of the RE theory, for explanations of distortions of the Sun, the Moon etc. If the RE theory is using that, why it is forbidden for the FET?
Let's be positive and do not use double standards. Either you believe your senses or not. If RET can use the refraction and atmospheric distortions to explain something, then the FET can do that, too. That seems fair.
However, for me that seems a bit too far away. I am not a specialist in atmospheric optics. Besides, I am not going to give away my freedom and right of making my own conclusion. I believe my eyes. I see that the Earth is flat. Therefore, it is flat.
It is actually very easy to prove that one can not trust their senses at face value. Just take any optical illusion (there are now illusions for other senses too, not just vision).
So it is absolutely proven that we can not just trust our senses.
This also means that if we look out our window and see that the Earth looks flat, we can not trust that wither.
The only conclusion is, is that we can not just do a simple examination and trust that the results are what we think they look like.
But as you tried to say, what can we do about it? How can we resolve this dilemma?
It is easy. It is only superficial examinations that lead us to mistake illusion for reality. When we examin these situations more carefully, we can show that what we think we are seeing is really an illusion.
take for example this illusion:
http://en.wikipedia.org/wiki/File:Caf%C3%A9_wall.svg (if you don't want to just click on a link, you can search for the Cafe wall illusion on wikipeida).
At first glance, you would say that the lines are slopped (narrower at one end and thicker at the other).
But, if you go beyond just superficial examination, you can actually determine that the lines are actually straight. It is a simple matter of holding a ruler up to the screen and checking the lines. And you can check that the rule is really straight by using simple geometry: A straight line is the shortest path between two points (so two pins and a piece of string stretched between them would enable you to check the ruler's straightness).
Actually, this is why, in science, that the method used to acquire the data is so important (actually more important then the data itself). Because in science, it is always assumed that the data could be wrong, but if the procedure is given, then this can be checked without encountering illusionary data. If the procedure can be show to be valid, then the results of that procedure can be trusted.
As it has been shown, superficial examination, as a procedure, is flawed. Therefore we can not rely on a flawed method to supply us with the data we need. So just looking out your window and not seeing obvious curvature to the Earth is just superficial examination and therefore is flawed and not admissible as evidence (for either side).
Dear Edtharan,
Thanks for your interesting reply.
"Just take any optical illusion (there are now illusions for other senses too, not just vision).
So it is absolutely proven that we can not just trust our senses."
Do you mean that the existence of illusions constitutes an absolute proof that we can not trust our senses? by the way, what is the difference between "trust our senses" and "just trust our senses" or "trust senses
at face value"?
My opinion is that either you trust your senses (understanding, of course, that illusions may happen) or you do not trust your senses.
"This also means that if we look out our window and see that the Earth looks flat, we can not trust that wither."
It does not, unless you presume that the world around you is a huge optical illusion. This is actually a very good point. So, it seems we both can agree that, according to RET, what one sees is an illusion, not a reality and we can not trust our senses. According to FET, as far as I understand, what one sees is a reality, though illusions may happen.
"As it has been shown, superficial examination, as a procedure, is flawed."
You have not shown that, just declared: "It is only superficial examinations that lead us to mistake illusion for reality."
You can not start from the point you are going to prove.
"So just looking out your window"...
It is called "observation", a very important procedure in science, by the way.
... "and not seeing obvious curvature to the Earth"
If it is
obvious, why we can not see it?
"is just superficial examination"
What is the difference between observation and "superficial examination"?
"and therefore is flawed"
If "superficial examination" is flawed by your definition and
"looking out your window... is just superficial examination and therefore is flawed and not admissible as evidence"how can you trust PICTURES of the sky that you can see through a telescope or a camera lens? How can you trust the photo we are discussing? Do you presume that "looking out your window" produces an illusion, but looking through a telescope gives you a real picture? If not - you have just proved my point. If yes - please explain why.
In other words, if "looking out your window... is flawed and not admissible as evidence (for either side)", then looking through a telescope should not be "admissible as evidence (for either side)". Agreed?
