Well there is this in The New Testament:

"Honour all men. Love the brotherhood. Fear God. Honour the king."
1 Peter 2:17, KJV

What do you think of the concept of "choosing to believe" however? Me. I believe something because I am "compelled too", having sifted through the evidence. The Idea of choosing to believe something because you get some goodies if you do, is just nonsense to me.

Well, I kind of did. It was framed as "choosing to accept Jesus into my life", but it was basically what you're talking about. My explanation? I was young, and was still working out how stuff worked, I guess. Hard to say.

Actually the idea is very very old and seems to go back to Marcion of Sinope c. 140s CE with him saying the OT god was a demiurge created by the true God. This view partly survives in our bible as 2 Corinthians 4:4. He is also credited with creating the first Bible - "Paul"'s writings and a different version of Luke

Considering that I've mentioned "unsound" several times in this thread alone -- which is the proper name for an argument when the premises are false -- I'm not sure why do you think you need to say that.

Other than, of course, AGAIN just posting random smart-sounding stuff as a dodge.

Honestly, at this point I'm wondering what your point even is in this thread. As in, at all. You just seem to pop up randomly to spew some irrelevant truisms that don't even seem to connect to the message you were answering to, or really to whatever was being discussed.

Except, of course, that

1. That still doesn't answer the question in the message you're answering to.

2. you're just equivocating again. "Everybody" ignored the evidence? Really? I mean, you just mentioned yourself several people who weren't ignoring the problems. And there were many many more.

For a start, the whole thing was presented at a GEOLOGY conference, not a palaeontology one. Most of the actual palaeontologists were actually in the camp of calling it a fraud. The ones defending it tended to be more from vaguely related fields like, yes, anthropologists. Though even those were a minority, compared to where the thing was REALLY a hit: namely sensationalist journalists.

3. also you don't seem to understand how science works. Which you probably should, before criticizing how it's applied.

The fact is that at the time there actually weren't any actual hominid fossils from between H Heidelbergensis and H Sapiens or Neanderthals. Expecting someone to know a priori that the model of brain evolving first is wrong, expects pretty much omniscience.

That's not how science works. We build models based on available data. Usually they're wrong in some way. (As the saying goes, every scientist who ever lived was wrong.) We revise them if and when new data contradicts them. Or not, if new data supports them.

Yes, there were OTHER signs that shouldn't have been ignored, but the basic idea of going with the current model if the latest finds seem to support it is not wrong.

The idea that ha ha, silly scientists accepted stuff because it fit the model, is just... showing a profound lack of understanding how that process works. You adjust your model based on new data, NOT expect to know that a model is wrong before you have the data to prove it wrong.

4. ... which is what seems to get you down the wrong rabbithole. In fact, if you look at who ran with it all the way, most had some other agenda, than just wanting to validate the model or not. In fact, THE most common denominator by far were nationalism and racism. Comparing it to the current model was not the wrong part, nor the real driving force. Wanting to have some justification for completely non-scientific bigotry was.

It's easy to satirize, when you're not constrained by having to be honest. But it proves... what?

In fact, it just seems to me like it just goes full circle to what you were saying at the beginning of this message: if you lie about the premises, and equivocate heavily for good measure too, sure, you can take a valid method and arrive at some bogus conclusions. But unlike what you seem to believe, that doesn't mean you did a kind of ad absurdum disproof of the method.

Could we perhaps describe it as you being convinced of the truth of the Jesus stuff, because of the evidence of the happy smiling faces of those that had done just that? I can accept this as having more credibility than just choosing to believe.

I stand by my position:

I think the idea of choosing to believe in a god so as to be rewarded by that god if he happens to exist is nonsense.

*shrug* Frame it however you will. I definitely feel like I made a decision at that time. Of course, it was a long long time ago, and you know what they say about memory.

Well, upon thinking about it some more, I think you SORTA can decide. Perhaps not as in directly "do I want to believe X is true", which probably almost everyone would spot the problem with, but as in "do I trust this guy?" Pretty much just moving the problem one step further.

And at least as a kid, trusting your parents comes very naturally. Well, at least as long as they haven't gone out of their way to sabotage that.

Yet not even people who had no vested interest in Piltdown accepted even when the most casual study would have shown it was a fake.

Another example is before Plate Tectonics there was this insane idea of land bridges between the various continents (like South America and Africa) which was built on the theory that the continents didn't move. The idea that such a huge land mass could simple disappear is silly beyond belief.

1. Actually fewer than you'd think, when you take out those with a racist or nationalist agenda. E.g., even just looking at the stark difference in acceptance between the UK (where some wanted it to show that the British evolved a big brain first; never mind that history said they're not the descendants of those hypothetical hominids anyway) and the rest of the world, kinda drives that point home. When you move out of the rah-rah-rah nationalistic chest-thumping circles, almost everyone (who was qualified to make that call, as opposed to geologists and whatnot chiming in with their uninformed opinion) had no problem saying that nope, those two aren't even fitting together.


2. Either way, that still doesn't say what you seem to want it to say.

Having the wrong model is NOT a problem for the scientific method. The existing model is what you're trying to falsify. All those existing theories and whatnot? Those are your model. And you're trying to prove that model wrong. That's how you get a better model. That's the whole POINT of science.

IF you're doing science, that is.

If you're stuck defending the model against new data, that's the polar opposite of doing science.

So basically all you're showing isn't some failure of the scientific method, but some failure to use the scientific method in the first place. As in, yeah, some people were not doing science. That's all there is to it. How the f-bomb does that illustrate any problem with the scientific method or its application, then?

So basically you're requiring omniscience? As in, to somehow have a fully correct model before the data or supporting theories for it?

Learn what science even means and how it works, silly, before presuming to criticize it. Your being too intellectually unequipped to understand it isn't a failure of science. It's just your failure.

Yes. It's the same "Science was wrong before (with wrong defined as not 100% perfectly correct and completed picture about everything immediately out of the gate) therefore Woo" argument.

Science has been wrong before it was corrected with more, better science.

Woo has always been wrong about everything.

Pretty much.

I'm only surprised it comes from Maximara this time, really. Could have sworn they were way smarter than that. But I guess I can be wrong too

I am smarter then that. I think what you have missed is the point I am actually making: to even begin getting data you have to have a concept about how things work and that concept determines on what data is "valid".

For example, take the Christ Myth theory a debate that has woo on both sides because the there is the hypothesis that Jesus existence is a yes or no question rather then going deeper and asking the key question 'why is meant by historical?'

Is it Jesus had to live in the time the Gospels claim or can he have lived nearly a century earlier or 30 years later? It is that the gospels describe the highly mythologized life of an actual 1st century preacher or can he be a preexisting celestial being that the actions of one or more would be messiahs were added to? Was there a pagan group called Chrestians, is that as is claimed just another name of Christians, or is it a mixture of the two?

Or how about the Aristotelian Cosmology woo that dominated Western thought for about 2000 years that the most basic use to the scientific method would have disproved large sections of?

On a side note did you know many of the various silly experiments in Balnibarbi (Gulliver's Travels) were taken nearly verbatim from actual experiments by the Royal Society?

A point Burke makes in the final episode of Day the Universe Changed (Worlds without End) and one Extra Credits reiterates (God Does Not Play Dice - The Danger of Unquestioned Belief) is you have to have a model (Burke calls it a structure and Extra Credits calls it postulates) to begin to determine what the supposedly "raw data" you are looking for even is.

"Without hypothesises, preconceptions of the world, how could you even begin research?" Burke uses some classic optical illusions to show this a basic level and later says this model "provides a rulebook for the kind of questions you ask about the world because it gives you the theory on how things are supposed to work." It is when a repeatable observation is made that doesn't fit the structure such as dropping two objects of different weight hitting the ground at different times (Aristotelian Cosmology) vs what really happens) that the structure has to change.

Extra Credit goes into how that structure can blind you by using Einstein's unwavering postulate that you could be certain about key aspects of the universe. This is why he rejected Quantum mechanics even after it had been deemed useful by the scientific community: "God does not play dice."

And if that happens at the hard science level then what about the soft sciences like history, psycology, psychiatry, or anthropology? Or sciences that are a blend of soft and hard like medicine, biology, and archeology?

Still not sure what the point even is.

Much less how it connects to the only point I was making when you started this detour: that yes, it's valid to apply a hypothesis on other values than what the original author did, and in fact we have the scientific method as an example of something that's BASED on that.

But ok, let's go through it point by point:

1. The data is what you need to explain. If it's reproducible or otherwise reliable, that's it. It's not "valid" or "invalid", it just is. That's what you need to explain.

The model is what explains it.

You don't decide what is "valid" or not, by how it fits a model. In fact, discarding data because it doesn't fit the existing model is exactly b-ass-ackwards if you're actually doing science. It's in fact the polar opposite of doing science.

The model may give you hints at where to look for more data that might or might not contradict the model, that you wouldn't have otherwise looked for. Like how having a GR frame dragging equation gave people the idea to do the Gravity Probe B experiment to see if it actually happens. But that's a completely different thing than deciding which data is "valid" and which isn't.


2. And it certainly doesn't prevent you from having data that you don't have a model for at all. In fact, for just about every single domain, historically we started at a point where we didn't have the foggiest idea of how or what happens, and we had to start making a model from scratch.

E.g., before Newton could figure out the law of gravity, we started at a point where we had NO idea why the planet orbits are what they are. We DIDN'T have "a concept about how things work." No, seriously, best we had was "because God moves them that way." (See, Aquinas.) It still was data that needed to be explained.

E.g., even the Aristotelian model that you mention, someone had to come up with that stuff in the first place. Why do some things fall faster than others? Why does the same horse pull an empty cart faster than a loaded cart? We had no idea. But it was data and someone had to come up with some explanation. Hell, they even had to come up with a system (not quite scientific yet, but still) that would provide an explanation.

Etc.

Sure, later some other people proved that model wrong by coming up with a better one, but that does NOT mean that "to even begin getting data you have to have a concept about how things work." If that were the case, no new domain would have ever gotten off the ground in the first place.


3. "Or how about the Aristotelian Cosmology woo that dominated Western thought for about 2000 years that the most basic use to the scientific method would have disproved large sections of?" is just about the most nonsense thing I've read recently, even topping most of the apologist stuff. It's really as stupid a question as asking why did Columbus sail to discover America, instead of looking on Google maps.

The scientific method didn't EXIST yet, silly. The whole struggle around the 17'th century or so was to replace the Aristotelian system with what would become the scientific method.


4. It also didn't help that the Aristotelian system had the church's backing. And not even the whole Aristotelian system. The Pope pretty much dictated what you can teach in a university, and what you can not. Even a whole chunk of the Aristotelian system was excluded.

And most of the personnel of those universities were clergy. And the Papal Inquisition cracked down the hardest on its own ranks. Things that you could maybe get away with as a layperson, were utterly not safe to say if you were a member of the church.

So, uh, yeah: gee, I wonder why didn't people use a yet non-existent method, during a time when you could be burned at the stake for deviating from the official method?


5. "It is when a repeatable observation is made that doesn't fit the structure such as dropping two objects of different weight hitting the ground at different times (Aristotelian Cosmology) vs what really happens) that the structure has to change." Uh, yes, so? Since the job of the model is to explain the data, OF COURSE it only changes when you actually have data that isn't explained by the existing one.

Basically you still seem to be demanding omniscience, as in, to have a complete and fully correct model before you even have any data to base it on. Which is stupid.

That's not how science works.


6. It's also historically incorrect, which is weird coming from someone with a history background. Galileo didn't actually need to drop two cannonballs like the myth goes. He actually could go jiujitsu style, as in, fully Aristotle thought experiment on it: what happens if you drop two cannonballs of different weights and tie them with a piece of chain. Cf Aristotle, on one hand the smaller one (which naturally falls slower) should pretty much be braking the larger one (which tends to fall faster), but on the other hand the whole body of the two tied together would fall faster than either of them.

He did an ad absurdum, really.

(And, honestly, going 2000 years without someone noticing THAT problem is the much more mind-boggling thing.)


7. You're including HJ discussions under science or the scientific method? REALLY? SERIOUSLY?


All in all, you seriously don't convince me that you even understand what science is at all.

You don't decide what is "valid" or not, by how it fits a model.
Actually you do in the soft sciences all the time. Dunnel and Binford debated the issue 'does style have function' in anthological and archeology for nearly a decade and after all that got to 'maybe'.

A perfect example of this taken straight from one of my classes is the American migration vs the Australian one. At that time scientists had found out even with low sea levels you couldn't get a full land bridge to Australia so they must have used primitive boats (even though we have no evidence of such boats). But this alternative isn't even considered with regards to American migration even though it would explain some of the hiccups in the archeological record seen in Americas

Points to the Christ myth theory and yes history is a science.

E.g., before Newton could figure out the law of gravity, we started at a point where we had NO idea why the planet orbits are what they are. We DIDN'T have "a concept about how things work." No, seriously, best we had was "because God moves them that way." (See, Aquinas.) It still was data that needed to be explained.
Actually they had several. There was Aristotle's model (still being held on by the Catholic Church down south), Johannes Kepler's perfect solid model (which he was forced to throw out as he got most measurements), whatever Aldus Manutius has found regarding Aristarchus of Samos and so on.

In the absence of air they don't. Something Aristotle himself could have checked with two rocks rather than a rock and a feather.

More over Burke gives some more insane examples of how off the wall of the Aristotelian model was. Straight lines only on Earth and curves only in heaven?! Did Aristotle never see a spear (something around since the freaking Stone Age) in flight?! I though it was Homer who was blind.

But people would know that heavier objects are harder to carry (more fatiguing) so it would follow the same for the horse.

It's really as stupid a question as asking why did Columbus sail to discover America, instead of looking on Google maps
That is so non sequitur that I am surprised you even made it. Columbus sailed west because his geography was messed up between Asia being seen longer than it really (Toscanelli map, 1474) and having a Earth far smaller in diameter then it really was (Day the Universe Changed - Point of View). And the only reason he tried that was the Europeans were tired of paying the Arabs for the spices out East. But one of Portugal's sailors finally got around the tip of Africa and so the idea was largely DOA. In fact, it is kind of miracle Columbus was able to sale the idea to Spain.

Which chunk? In fact the way the Anglican and Catholic Churches handled the vacuum is a perfect example of how the postulates shape the acceptance of data. The Catholic Church said the vacuum couldn't exist because Aristotle said there were no "holes" in the universe.

But according to Burke the Anglican Church took a different tack and said the vacuum was filled by something outside of our normal experience (basically angels and souls) and if they existed so did God and his authority on Earth through the King so it was "Long Live the Vacuum" .

In fact, the Catholic Church could have gotten around the whole mess Aristotle via the shadows on the cave wall example which also dated back to the ancient Greeks. The heaven people saw up there was a shadow of the real one and so of course it didn't behave like the "real" heaven. Ironically to fix the calendar the Catholic Church had effectively thrown Aristotle out on his ear and adopted Copernicus' model for the simple reason the Aristotle was, by that time, a Rude Goldberg on an acid trip mathematical nightmare with some 90 little "fiddly bits" to get things work. It was only when Galileo made a fuss that things got nasty as up to then Copernicus' model had been blown off as a "mathematical device".

Uh, yes, so? Since the job of the model is to explain the data, OF COURSE it only changes when you actually have data that isn't explained by the existing one.
Yet anyone in Aristotle's time or later could have shown he was talking nonsense. Then there was the whole straight lines on Earth circles only in heaven nonsense. As I said before did Aristotle never seen a spear thrown?

He actually could go jiujitsu style, as in, fully Aristotle thought experiment on it: what happens if you drop two cannonballs of different weights and tie them with a piece of chain. Cf Aristotle, on one hand the smaller one (which naturally falls slower) should pretty much be braking the larger one (which tends to fall faster), but on the other hand the whole body of the two tied together would fall faster than either of them.

He did an ad absurdum, really.
Which could have been performed with different materials in Aristotle's time

History is a soft science so yes.

I could write more, but basically none of what you write there has anything to do with the scientific method.

Criticizing the scientific method because of what its predecessor, the Aristotelian system did -- even after having it pointed out to you that they're different and the former didn't even exist until some 2000 years after Aristotle -- is... just stupid beyond belief. It's literally like criticizing Chemistry for the beliefs of Alchemy, or like those who criticized Obama for stuff actually done by Bush.

As for history, there's a reason why it's called the HISTORICAL METHOD, not the SCIENTIFIC METHOD. So again, you're criticizing the latter without apparently even having a clue what it is.

Edit: I mean, don't get me wrong, I'm even a fan of the modern historical method, but it's a different thing from the scientific method. You can't criticize the latter for the sins of the former, nor viceversa.

That said, if you want to discuss Aristotle -- again, especially for someone claiming to do history -- it would help if you discussed what he actually said, not what you misunderstood at the end of a game of Chinese whispers.

Aristotle's argument against a vacuum was more than just "there are no holes in nature." It was based upon such stuff as that in his system the speed at which something falls, all else being equal, was proportional to its weight (hence the two weights problem) and inversely proportional to the density of the medium (hence stuff falling slower in water than in air.) Basically he was kinda close to discovering drag, but basically instead of applying it as a force in the opposite direction, he just divided by density. So if there were a vacuum anywhere, you'd have nature dividing by zero.

It's not even the daftest thing he wrote, but there we go: it even had a formula. It wasn't as simple as imagining holes in the skies, and it wasn't really solvable by going Plato's cave on its ass. You needed a better formula first. Which also needed better instruments first.

And, honestly, even the existence of the moons of Jupiter was a bigger problem for the Aristotelian system. As I was saying, it had dafter things in it than the falling speed formula, and that was one of the places where it did. Which is why it starts really crashing down after Galileo.

But, again, this was not the scientific method, nor anything even vaguely resembling the scientific method.


As for which parts did the Catholics forbid teaching, well, pretty much anything contrary to the official dogma or contradicting the bible, really.

The biggest or arguably most important chunk was Aristotle's multiple worlds. It was explicitly forbidden by name, so to speak. And they cared enough about that, for it to actually be one of the charges in Giordano Bruno's trial. And they were quite adamant that he must give up ALL those ideas (including this one,) not just some of them. Quite literally, believing there may be more than one 'Earth', instead of Earth being a one-off that God personally lovingly created, was enough of a charge to warrant a good ol' burning at the stake even by itself.

But pretty much the whole Bible was a minefield, in addition to where they explicitly said that this chunk of Aristotle is out. One example I keep using was their problem with heliocentrism, namely that OT verse where God stops the sun in the sky. It really depended on what cardinal or pope you asked, whether you're allowed to contradict that or not. Hell even the same pope was more than ok with it and encouraged Galileo to write his book about it... right until Galileo flamed him brutally in that book. At which point he had Galileo tried for... contradicting the exact same verse. Basically the same pope, in the same year, made a 180 degree turn as to whether you're allowed to contradict the same verse, based on no more than really wanting to show someone who's the boss. THAT arbitrary.

And make no mistake, if Galileo had been clergy like Giordano Bruno, he would have very probably been burned. So, yeah, there you have it. If you wondered why the clergy staffing the universities at the time didn't just ditch what the pope said they should teach and do their own thing, yeah, the Papal Inquisition may well be why

Actually, screw it, let's talk about the Gregorian calendar too, since I don't know where the hell do you even get all these pseudo-historical ideas from.

It had exactly NOTHING to do with the Copernican system, which, no, wasn't adopted by the Church at the time. For anything.

Not the least because Copernicus wanted everything to be perfect, hence perfectly circular orbits, hence it actually had WORSE predictive power than the old epicycles. Literally, Copernicus did worse at predicting planet positions than even the old Antikythera mechanism, almost 2000 years before. It wasn't until Kepler's elliptical orbits that it actually was usable for anything.

The notion that the Church somehow secretly favoured Copernicus as MORE accurate, or that that's how they got a more accurate calendar is just nuts. It's 100% counter-factual.

Nor did the old calendar have ANYTHING to do with Aristotle, really. It was called the JULIAN calendar for a reason, you know?

Anyway, the problem was known long before Copernicus was even born. The first who mentions it (as far as we know) was Bede in the 8'th century, for crying out loud. It was also mentioned by such figures as Dante Alighieri, and you probably never thought of him as a copernican scientist, right? You know, what with living a long time before Copernicus was even born? I mean, right?

And the final tables that would eventually be used to setting the calendar straight were also there before Copernicus was even born. See, for example, Tabule illustrissimi principis regis alfonsii, published somewhere between 1401 and 1404.

It literally only had to do with the position of stuff in the sky at certain dates, and bringing Christmas back in sync (sky-wise) with how it was at the time of the Council of Nicaea. It had literally NOTHING to do with how Copernicus said that that stuff moved. In fact, you didn't need ANY model for that. You just needed to know that the observed motion of the skies has a period slightly different from the Julian year in use at the time. You didn't need to explain WHY, as in, how they moved or what moved them. You just needed to know that things are shifting a bit each year, and by how much, and work out how much that meant since the time of Nicaea. That was it.
