I don't know anyone that says anything like that. Do you? Really?
But.. sol invictus... in a way... you are saying that yourself!
I strongly suspect that our ideas are basically sound and correct, and that the progress in the future will continue to take place in the incremental way it has over the last four centuries or so - major ideas won't be overturned outright, they will merely be modified into more exact and broadly applicable theories.
Now, please take in to the account that this doesn't mean that you are recalcitrant or boring, unless you are arrogant when you "correct" others.
I believe revolutions are to come, that will reshape basically everything we know and believe as "established knowledge". I believe that our approaches are naive but not because we are stupid, but because we have this "need to be certain about what we know". This is how we work.
Now, to depict a bit of the audacity some people demonstrate in the forums (regarding they are confident in that what they say is correct, accurate and true), I did a very simple search. The phrase "that's a fact" have been pronounced [SIZE=-1]
12,100 times.
My reading of this (fact) is that people in here is certain about what they are saying is undoubtedly true, in the purest and deeper sense of the word. In general, nor materialists nor idealists nor woos claim in here "I believe this" or "in my opinion that". [/SIZE]
Naive and obtuse? That seems very unlikely. If there's one thing I've learned from studying the history of ideas, it's that people in the past thought along very similar lines as we do now.
The four elements. The flat earth. The firmament. The geocentrical universe. Phlogiston. Ex-nihilo. Witchcraft. Gods and demons.... you name it. Think about this, most of this ideas were hold as "TRUE" for generations, they were believed by very intelligent individuals, people who was considered informed at the time. Heck, up to this days some of them prevail in some cultures/areas.
They were neither more intelligent nor more stupid. They merely knew less, were a little less organized and systematic, and they made some assumptions that turned out to be wrong, got stuck in some ruts that took centuries or even millenia to escape... but given what they knew, they came to the same kinds of conclusions and made the same kind of mistakes I or any other modern individual would in their situation.
I'm not sure about the "they knew less". They believed different, that's correct. I'm not saying anyone is particularly stupid, but naive, and in some cases obtuse. Besides, my point is that these ideas were once believed to be "a true depiction of the real world". Again, this does not render them stupid, but if they defended such beliefs with passion, claiming that they really had a TRUE depiction of the REAL WORLD, yes.. they were being obtuse and naive.
I'm sure some of our current scientific ideas are wrong. But I'm almost equally sure that future generations will look back and understand full well the valid reasoning that lead to those mistakes. And you will find that good scientists today freely acknowledge our ignorance of many aspects of the world, and the tentative nature of the conclusions we are able to draw.
Valid reasoning given the previous ideas and world views? Yes. And yes, many good scientists (and lots of forum members) are aware of our ignorance. But then again, not everyone.
The theory of gravity is an excellent example. Newton's theory has now been replaced by Einstein's general relativity. But Newtonian gravity isn't wrong - it's an approximation that isn't always valid, but very often is. Mathematically, general relativity reduces to Newtonian gravity when the gravitational fields involved are weak. It is inconceivable that Newton could have done any better, given what he knew. Einstein's theory required mathematics and physics concepts that weren't developed until more than a century after Newton's death. But when it came, the revolution was really fairly mild. NASA still uses Newton for most problems in orbital dynamics, and when relativity is necessary to take into account, it's as a small correction to Newton.
I'm not claiming theoretical accounts are wrong, the example is interesting because we are talking about to very different things here. First, equations that describe the relative movements of objects with different masses and trajectories. Another is the claim about that gravity IS a force. My take? it can be described as a force, it matters zero what it is, because science is not worried about what things "are" but about how we can describe its behaviour.
In this sense, when I talk to somebody who claims that "X is Y" I know I'm talking to a naive materialist. Statements like "the world is made of matter" are pretty convicing when talking to some woos... but utterly absurd when discussing at a different level.
