Instead of saying that Russell debunks all the myths, why not cite a myth or two and show how Russell debunks 'em? --Ed Poor
Has anyone else noticed that this article contradicts itself? Also, which Greek philosophers thought that? Also, from the way this is written, oone could infer that Russell is writing outside his field. Russell is a medievalist who specializes in History of Christianity and the problems of evil and the Devil -- however, he *has* been teaching the first third of the western Civ sequence for about 25 years...and is well-respected by his peers. I am removing the links to Amazon and Pricescan, since I see no valid reason for thier existenceunless they are sponsoring the wikipedia. JHK
Thales and his friends thought so. Or at the very least, some of them did. And even without them, it would still be quite definitely the general impression the early Greeks had of geography. Noone suspects the world is round until you've journeyed far enough to have a reason to suppose otherwise. I suspect what Russell was really saying is that no educated people during late Antiquity and the Middle Ages thought the world was flat, but I'm not going to change the page since I have no way to be sure. It's a mess as it stands, though.
I read that pythagoras wrote the earth was round, and some other greek guy a few hundred years later calculated (fairly accurately!) the circumference of the earth somehow by measuring sun angles between two cities. I've also heard that sailors were pretty sure the earth was round since they could see boats go ever the horizon of water

Yup. But these were later Greeks, and besides, not everyone decided the world was round at the same time.
Hmmm. No one suspects the world is round until you've been somewhere? Even besides the tremendous geographical condescension to ancient people, who travelled rather a lot, there's the old disappearing mast example. You yourself don't have to sail to see the masts gradually disappear. --MichaelTinkler
You do have to be by the ocean, which a lot of people aren't. besides, it might not occur to people even by the water, as much as people who traverse it because it is a more frequent and relevant occurance.
Well that sure wouldn't apply to the Greeks, all of whom lived reasonably close to the sea. --MichaelTinkler
The thing is that the connection between the masts and a curved Earth will not come up unless you start thinking about one or the other. Why do you suppose an ancient mariner would find it the least bit unusual that ships disappear, when he does not understand geometry or light and so much else in the world? Also, before the Greeks, it would be hard to say that people habitually tried to sort such problems out. This is not condescension, it's simply the way things were, and besides I doubt most modern people would make the connection. Things hide in plain sight all the time - that the universe is non-static is an obvious conclusion of Newtonian physics, but it took until relativity for it to be noticed.
Now various ancient peoples made various voyages of various lengths. The Greeks had begun sailing all over the Mediterranean by this time, the Phoenicians a while earlier and farther, and before that there were various commercial contacts all over the place. And there's no doubt the Mesopotamians kept records of the stars of far higher caliber than is needed to notice the differences between latitudes. But that doesn't mean they actually concluded the world is round, and far more to the point that doesn't mean they told everyone. If the Egyptians had figured it out (something I don't know about), it would say nothing about whether the Greeks knew. In their early descriptions, they have the world as a disc ringed by the river Oceanus, between the heavens and the underworld. That comes from their mythology, and then from the early philosophers like Anaxaminder, and is unquestionably flat.
If you are keeping a lookout for other ships, or landmasses you are approaching, then the curvature of the earth could very well become something you notice, since it interferes with your job. additionally, you don't need to know geometry to notice that if something goes over a curved hill, it disappears because of the curvature. I also suspect that some sailors knew at least basic geometry, considering it was used for navigation even back then. As to wether they told everyone, I agree that thats important. I also suspect that they would see no reason to write it down or casually tell anybody on land about it. I also happen to believe that the theory is almost completely unprovable, but I brought it up because its mentioned all the time, and its not as implausible as all you seem to think. its just as easy for me to validly argue its plausible as it is for anyone else to argue its not. that doesn't mean its true, but don't tell me its not true because its not plausible.
I'm not arguing that its not plausible, just that it's equally plausible that people would miss this despite it being easily available. And Ed, I am not just speculating. Here, a quick search pulls up http://library.scar.utoronto.ca/Classicsc42/Halkidis/carto-geo.htm, which confirms a decent list of names: Anaxaminder, Hecataeus, Herodotus and so forth. Plus it says that Pythagoras is questionable on the issue. Actually, it would be good info for the article, which I might work in some time if noone beats me to it.
And actually, looking at the reviews of Russell's book, noone says anything about him claiming anything about the times beyond the Middle Ages. So I've assumed that he is following the conventional wisdom and just changed the article to what is actually the case. Plus, Russell it would seem is not beyond criticism (http://www.sfu.ca/philosophy/swartz/flat_earth.htm), and I've mentioned that to.
It's flat, dammit! Flat! Flat! Flat!
Good, good. I've nothing against Russell, note, so long as he isn't claiming things that are obviously untrue, and the idea that the flat Earth dominated the Middle Ages is an important falsehood to debunk. I added the criticisms mainly because I ran across them while searching for details. In Greek Mythology, the world is definitely flat-flat, but it would be fair to say that in most Classical thought it was a curved disc on a sphere. I don't think anyone had much faith that there was stuff on the other side of the ocean.
OK, I have provided a more comprehensive discussion, I'm not up to date regarding the naming convention esp. for "Saints" etc., so I would appreciate it if someone could go over the link titles. --Eloquence 23:55 Feb 12, 2003 (UTC)
