: Actually, the story isn't quite that simple. The flat versus spherical debate (not to mention infinite variations) raged for a long time. It certainly IS true that most educated people knew a long time ago that the question had been settled, but it was by no means a dead issue as late as the mid-15th century......any more than evolution versus intelligent design is today. Washington Irving may have popularized the myth about Columbus, but many of the sailors aboard his vessels undoubtedly had serious concerns about this spherical Earth "theory." Incidentally, while Columbus was obviously right about the shape of the Earth, he was WAY wrong about its size (thus leading him to believe that he'd arrived at the East Indies).......which had been pretty accurately estimated by a number of folks centuries earlier. Wolfgang "Settled" might be an overstatement-- after all, we still have flat earthers today. There do seem to be some historians that hold that the flat earth theorists were influential at the later Middle Ages, but most historians seem to agree that based upon a relative scarcity of traceable reference to a flat earth after about 800AD, the influence was marginal. As for Columbus, if he did in fact use a flat vs spherical Earth hypothesis to bilk Spain out of funds, it certainly wouldn't be the last time a scientist set up to disprove a straw horse to secure funding (but it might have been the first!) Size was a different matter. I think that the Late Middle Age "natural philosophers" had a fair problem understanding scale, and the fact that people didn't understand that the distance of stars was so vast as to preclude parallax errors was responsible for geocentrism holding on as long as it did. This isn't what gave Columbus problems, though. Indeed, his estimation of how far he travelled is remarkably accurate given his dead reckoning preference (see http://www.columbusnavigation.com/v1a.shtml). The problem was that he used Ptolemy's huge underestimation of circumference. Almost 500 years before Ptolemy, Eratosthenes had an estimation of circumference to within 8%. While he preferred dead reckoning, Columbus also had a quadrant on board. I would think that a well developed technique for quadrant based navigation at Columbus' time would indicate a well developed sense of a spherical earth. -- Scott Reverse name to reply |

The enlightened do not. That's pretty bold, calling something "crap" when you don't know anything whatsoever about it. Decades of my scientific training, including federal grant review responsiblities, all teach me that an untestable hypothesis expounded as "truth"is shoddy science (aka, crap). Therefore, when we teach something like this, we don't make believe that it is good science. IOW, that's your "untestable hypothesis expounded as truth"... In fact, we try to make it clear that its not science at all. I don't think it is "science" and I don't suggest it be called "science." But I don't think that trying to hide the idea that it is the way life came about is conducive to education, and I certainly don't think that all information provided in a general "science" class must be universally agreed as "science." Theologans and religious instructors are perfectly free to discuss such matters all they want, with whoever I want. If its taught as science in a school system supported by my tax dollars, I'll be at the top of the class action suit. Now there's an open-minded attitude AND a great use of the court system! HTH, R |

I mean after typing the above, can you? Like your "clarification" made any difference to anything at all? Obviously not to you and a few others. And you're perfectly entitled to be as wrong as you decide to be. That said, I agree that people should be "taught" about both, as well as about religion. I don't think "intelligent design" is the way life came about and evolution is the more-reasonable explanation, but I'm certainly aware of both, and I'd make sure my children were as well. And I think you'll find that most voters would want their kids as well-educated as possible, and many of those would truly believe that intelligent design is the more-reasonable explanation. So let's say clearly what you mean: to be well educated you must be "informed about" ID. Is that what I mean? Well, thankfully, you're here to explain it... I bet McCain never says that, ever ... I mean they're kicking school boards out in that blue of blue states, Kansas for pushing ID. What's sad is that McCain is pandering, but God knows what you're doing. You may actually believe what you write. Let me be clear: I've seen the greatest minds of my generation and they don't know **** about Intelligent Design. Well, sure, but one really shouldn't hold that against a bunch of 10 year old kids, no matter how much smarter they are than you... |

And you arrived at this new untestable hypothesis expounded as truth how, exactly? and your absolute statement using the phrase "is" speaks well to your faith. Ah. No, it doesn't. The use of the _word_ "is" in the _phrase_ "it is" is completely accurate when describing the idea. The phrase nor its use speak to the writer's beliefs or faith. It would be the noun that would do that - i.e., if I had used the word "fact" rather than "idea," one might reasonably (but still possibly erroneously) guess that I personally believed it to be a fact. Others, in fact many others, don't believe this to be the case, and have a variety of hypothesis that all fall under the general class of "evolution". The hypotheses are close to, if not actually testable and demonstrable, are very consistent with current concepts of genetics, and none of them call for the precendent "and then a miracle occurred". For me, that last phrase really encompasses the difference between science and religion. All fair enough. And most of the former part of the above is why "evolution" cannot be "taught," only "taught about" without moving from hypothesizing to hypostatizing. And how do you reconcile the above, acknowledging the variety and the fact that the hypotheses are not absolutely "testable and demonstrable," with your pervious statement regarding "untestable hypothesis" being crap.

Now, now, Scott.....no need to resort to that sort of thing to beat up on a punching bag. dicklet may well believe that.....it would be thoroughly consistent with his perpetually demonstrated muddle-headeness.....if he had anything resembling beliefs at all.....but there is nothing in his sentence to support your contention. Best to just beat him up in the usual fashion. Others, in fact many others, don't believe this to be the case, and have a variety of hypothesis that all fall under the general class of "evolution". Here's a good place to use that much belabored word, "about." There are many theories "about" the mechanisms that drive evolution. Biological evolution itself is NOT theoretical. Biological evolution is a FACT! Moreover, it is just "about" the best documented and supported FACT in all of science. And what makes the whole continuing "debate" endlessly hilarious is that the first great proponent of the correct model got it right in all of its essential details on the very first try alomst a hundred-fifty years ago, and the vast majority on BOTH sides of the question STILL don't get it!! What could possibly be funnier?.......well, o.k., yeah, there's dicklet. ![]() The hypotheses are close to, if not actually testable and demonstrable, are very consistent with current concepts of genetics, Many hypothoses concerning evolutionary mechanisms are most assuredly testable.....and have been tested.....repeatedly.....and have passed brilliantly. and none of them call for the precendent "and then a miracle occurred". For me, that last phrase really encompasses the difference between science and religion. Oh, it's all miraculous enough. The trouble is that most folks don't understand what "miracle" means any more than they do "evolution." Wolfgang |
