Is this the Popper quote, from 1976, that you're searching for, sntjohnny:
Quote
"Darwinism is not a testable scientific theory but a metaphysical research program."


Or is it this 1978 one:
Quote
"The Mendelian underpinning of modern Darwinism has been well tested, and so has the theory of evolution which says that all terrestrial life has evolved from a few primitive unicellular organisms, possibly even from one single organism."


Or maybe this one from the same 1978 paper:
Quote
"I have changed my mind about the testability and logical status of the theory of natural selection, and I am glad to have the opportunity to make a recantation."

Quote from: Copernicus
Quote from: TheDoctor
Not necessarily, Cop.  If evolution were to be disproven, say, tomorrow, most of biology would continue on uninterrupted.  DNA would still be DNA and still function the same way, for example.


How could evolution be "disproven", Doc?  A better way of looking at science is that competing theories encompass earlier theories in that they account for all (or most) of the data accounted for in the earlier theory PLUS data that could not be accounted for earlier.  Theories don't just get "disproven" out of the blue.  They get superseded.


Again, Cog, you are assuming that I know nothing about science.  It's actually starting to make me somewhat upset.  Maybe you should try showing some respect.

One of Popper's characteristics of a scientific theory is "Every genuine test of a theory is an attempt to falsify it, or to refute it. Testability is falsifiability; but there are degrees of testability: some theories are more testable, more exposed to refutation, than others; they take, as it were, greater risks."  The definition of "refute" is "to disprove."

"I never said that it was 'unfalsifiable'."

No, of course you didn't.  :)

"In principle, it could be called into question by contrary data--e.g. rock strata that mixed fossils known to be from very different eons."

I fail to see why this would change anything.  It would only call for a re-thinking of the current chronology.  A neo-neo Darwinian synthesis, if you will.

Your other examples follow similarly.  They don't refute anything.

"Sntjohnny, forgive me if I don't trust your methodology for conducting surveys. Maybe you should have your study of doctors, biologists, biochemists and others published so that we could examine the details."

Well, that's fine.  Why don't you start asking the people you come in casual contact with?  I'm not talking about your college buddies.  So far, anyone that actually has to use the stuff doesn't need evolution.  Next time you're at the doctor's ask, "How did the theory of evolution inform your diagnosis?"  The looks are priceless!  But don't set it up.  That wouldn't be honest.  I just realized I should have asked the X-Ray technician who showed my my pneumonia back last November.  Dang it.  A missed opportunity.

"That is extremely poor practical advice."

Maybe you just haven't found a way to do it.

"Instead, I would suggest two things: First, learn how to think critically, and second, think critically."

In contrast to this, for the first one I would say 'learn how to examine your assumptions.'

This is a skill very few people have.  They start with what feels right and go from there.

"Once you learn how to think critically, then you'll be in a position to evaluate the scientific enterprise."

Once you've learned to examine your assumptions, you'll recognize that thinking that everything can be understood through the lens of science is not only silly, but highly impractical.  Science will not help you find a spouse.  Science can not help you recognize beauty.   Science won't help you write a love poem.  Science cannot answer the most important questions.  Science cannot rise above brute facts.  At least, not real science.

"Is this the Popper quote, from 1976, that you're searching for
"Darwinism is not a testable scientific theory but a metaphysical research program.""

Yea, that's it!  Good job!

"Or is it this 1978 one:Quote:
"The Mendelian underpinning of modern Darwinism has been well tested, and so has the theory of evolution which says that all terrestrial life has evolved from a few primitive unicellular organisms, possibly even from one single organism.""

Of course, as Popper well knows, Mendel is not the the disputable part.

"Or maybe this one from the same 1978 paper:Quote:
"I have changed my mind about the testability and logical status of the theory of natural selection, and I am glad to have the opportunity to make a recantation.""

Let's see.  *rummaging around my bag of atheistic tricks*  AH, here it is:  You're taking the quote out of context.

Do you have the rest of the context?

And it makes me a bit upset when someone accuses me of writing something that I did not write -- even though I might agree with it (which in this case, I do).

The post that has you "somewhat upset" is from Copernicus, not from me.

Contrast??? That is not contrast. To examine one's assumptions is a part of thinking critically.

Here, you've illegitimately conflated 'critical thinking' and 'science.' Critical thinking, while a part of science, is not science. Critical thinking CAN help one find a spouse, recognize beauty, write a love poem, and much, much more. Critical thinking is absolutely essential to the discovery of reliable answers to life's most important questions.

Did you not see the last part of Popper's sentence? Here it is just in case you missed it:
Quote
". . . has been well tested, and so has the theory of evolution which says that all terrestrial life has evolved from a few primitive unicellular organisms, possibly even from one single organism."
The philosopher of science Sir Karl Popper, like virtually all scientists, seems to think the theory of evolution has been well tested and you're telling us that evolution cannot be tested.

Hmm. Who should I believe? Tough decision. . . not.



Quote
Do you have the rest of the context?
You really are lazy, aren't you?  :wink:  Well, I'll see if I can find it. . . Yeah, here it is:
Quote
When speaking here of Darwinism, I shall speak always of today's theory--that is Darwin's own theory of natural selection supported by the Mendelian theory of heredity, by the theory of the mutation and recombination of genes in a gene pool, and the decoded genetic code. This is an immensely impressive and powerful theory. The claim that it completely explains evolution is of course a bold claim, and very far from being established. All scientific theories are conjectures, even those that have successfully passed many and varied tests. The Mendelian underpinning of modern Darwinism has been well tested, and so has the theory of evolution which says that all terrestrial life has evolved from a few primitive unicellular organisms, possibly even from one single organism.

However, Darwin's own most important contribution to the theory of evolution, his theory of natural selection, is difficult to test. There are some tests, even some experimental tests; and in some cases, such as the famous phenomenom known as "industrial melanism", we can observe natural selection happening under our very eyes, as it were. Nevertheless, really severe tests of the theory of natural selection are hard to come by, much more so than tests of otherwise comparable theories in physics or chemistry.

The fact that the theory of natural selection is difficult to test has led some people, anti-Darwinists and even some great Darwinists, to claim that it is a tautology. A tautology like "All tables are tables" is not, of course, testable; nor has it any explanatory power. It is therefore most surprising to hear that some of the greatest contemporary Darwinists themselves formulate the theory in such a way that it amounts to the tautology that those organisms that leave the most offspring leave the most offspring. And C.H. Waddington even says somewhere (and he defends this view in other places) that "Natural selection ... turns out ... to be a tautology". However, he attributes at the same place to the theory an "enormous power ... of explanation". Since the explanatory power of a tautology is obviously zero, something must be wrong here.

Yet similar passages can be found in the works of such great Darwinists as Ronald Fisher, J.B.S. Haldane, and George Gaylord Simpson; and others.

I mention this problem because I too belong among the culprits. Influenced by what these authorities say, I have in the past described the theory as "almost tautological", and I have tried to explain how the theory of natural selection could be untestable (as is a tautology) and yet of great scientific interest. My solution was that the doctrine of natural selection is a most successful metaphysical research programme. It raises detailed problems in many fields, and it tells us what we would expect of an acceptable solution of these problems.

I still believe that natural selection works this way as a research programme. Nevertheless, I have changed my mind about the testability and logical status of the theory of natural selection; and I am glad to have an opportunity to make a recantation. My recantation may, I hope, contribute a little to the understanding of the status of natural selection.
--------------------------------------------------------------------------------

From "Natural Selection and the Emergence of Mind", Dialectica, vol. 32, no. 3-4, 1978, pp. 339-355

Popper says that because natural selection is difficult to test, in the past he was among the culprits who described natural selection as "almost tautological." As a result he believed that natural selection amounted to no more than a very successful metaphysical research program.

However, although he still believes that natural selection can function in that manner as a research program, he's since changed his mind about the testability and logical status of the theory of natural selection.

As I have said before, it isn't easy to refute a theory that explains so many things, only one of which is the fossil record.  However, discovery of a "mixed layer" of fossils from several different eras would throw a huge monkey wrench into our scientific understanding of both evolution and geology.  Science depends crucially on the consistency of observations, and such a discovery would be taken as incompatible with know science.  Perhaps you "fail to see why this would change anything" because you really don't understand science.  You see it as some kind of alternative faith-based reasoning rather than skepticism overcome by recurring observation.

Given your misunderstanding of science, I think that they are still very much on the table.

First of all, I said that your methodology was screwed up.  Your reply was to invite me to make the same mistake.  Secondly, you seem to misunderstand the difference between applied and theoretical science.  A doctor would not have any reason to apply evolution theory directly in anything he does.  On the other hand, the science that underlies his methodology was based on biology, which depends crucially on evolution theory for its understanding of how biology works.  For example, doctors have been asked to stop prescribing antibiotics so freely because new strains of bacteria are evolving to survive known antibiotics.  It is evolution that allows us to understand why, and doctors accept the advice because of their acceptance of the explanation.

"Contrast??? That is not contrast. To examine one's assumptions is a part of thinking critically."

Yes it is.  But even more so it is indicative of intellectual integrity, which is an attitude.  Its a matter of having the willingness to go there in the first place.  You're only talking about the process by which the assumptions are evaluated.  I'm getting at bothering to do it in the first place.

"Here, you've illegitimately conflated 'critical thinking' and 'science.'"

You should re-examine your post.  You conflated 'critical thinking' and 'science,' and I reacted to it.  Thus, my remarks that science- true science- has limits on what it can say.

"Of course, as Popper well knows, Mendel is not the the disputable part.
Did you not see the last part of Popper's sentence?"

Absolutely I saw it.  What you quoted is consistent with 'Mendel is not the disputable part.'  

"you're telling us that evolution cannot be tested."

No, that is not what I'm saying.   These conversations would proceed so much more efficiently if people would stick to the words on the screen.

"I mention this problem because I too belong among the culprits. Influenced by what these authorities say,"

I just thought that was funny given the nature of your arguments.

"Nevertheless, I have changed my mind about the testability and logical status of the theory of natural selection; and I am glad to have an opportunity to make a recantation."

Why?  On what grounds?  What changed?

"However, although he still believes that natural selection can function in that manner as a research program, he's since changed his mind about the testability"

Was his original argument phrased as being against testability or falsifiability?  You do see that there is a difference?

You still have not provided the full context.   You are halfway there.

"Science depends crucially on the consistency of observations,"

That much is true.  Oh, how I pine for the day when it was a dependence on the consistency of EXPERIMENTAL observations.  Alas.

"Perhaps you "fail to see why this would change anything" because you really don't understand science."

No.  I fail to see why this would change anything because in this last century there have been plenty of examples of material that should have been d--ning to Darwinian evolution but was merely 'synthesized.'

People are creative.  They can find ways to synthesize anything.

"Given your misunderstanding of science, I think that they are still very much on the table."

Since you are not a scientist, you are not qualified to comment on my understanding of science.

"First of all, I said that your methodology was screwed up."

lol, well, by the time I'm 100 maybe I'll have seen the doctor enough to have dealt with a reasonable sample.

"Secondly, you seem to misunderstand the difference between applied and theoretical science."

Nope.  In fact, that's my point.  Especially in regards to evolution, it is 99% theoretical.

"A doctor would not have any reason to apply evolution theory directly in anything he does."

Exactly.

"On the other hand, the science that underlies his methodology was based on biology, which depends crucially on evolution theory for its understanding of how biology works."

Let's put this to the test.  How does evolution factor into our understanding of the Golgi Apparatus and how it works etc, in such a way that without the TOE it would be impossible to understand?

"For example, doctors have been asked to stop prescribing antibiotics so freely because new strains of bacteria are evolving to survive known antibiotics."

Priceless.

Do you have anything else?

Alas.  A day when science depended EXCLUSIVELY on  experimental observations never existed, except in your imagination.

Your vague handwaving reference does not affect my point, which was that a mixed rock stratum of the sort I described would be considered a shocking disconfirmation of evolution theory, since it would undermine one of the cornerstones of evidence for that theory.

First of all, linguistics is a cognitive science, and we do employ empirical techniques in the study of language.  However, I'm not making the comment as a scientist, but as someone who understands scientific methodology.  If you can find a bona fide scientist to back up your methodology, I will concede your point.

Again, your methodology is flawed.  The problem is not in the sample size but in the skewed method of collection.  You need to eliminate the sampling bias, among other things.  In the end, you might succeed in constructing an argument from popularity fallacy, although I fail to see how that would help your case.

Straw man.  I'm not saying that biology would be IMPOSSIBLE to understand without evolution theory.  In principle, some other explanation might work better.  We just have none.  Since you are interested in how evolution might explain the Golgi complex, I can only recommend that you google "golgi" and "evolution".  You'll come up with plenty of links.

"Alas. A day when science depended EXCLUSIVELY on experimental observations never existed, except in your imagination."

Exclusivity wasn't exactly what I was arguing for, either.

"Your vague handwaving reference does not affect my point, which was that a mixed rock stratum of the sort I described would be considered a shocking disconfirmation of evolution theory, since it would undermine one of the cornerstones of evidence for that theory."

No, it really wouldn't.  Take punctuated equilbrium, for example.  From top to bottom, PE is a challenge to the neo-darwinian synthesis.  The idea is that the fossil record ill-records a slow gradualistic evolution, suggesting that in fact species evolved very quickly.  That's what the fossil record shows.  Dawkins and Gould himself are quick to rescue the theory by insisting that fast or slow, the changes are still step-wise.   The net result from a falsifiability POV:  Whether you have 500 million years or 5 million years, evolutionists can retain their theory.  The very thing which at one time was what allowed them to think their view was plausible is now irrelevant.  Except, of course, as it suits them.  I'm thinking of all your mumbo jumbo about how long 500 million years is.  PE 'shows' that evolution does not need '500 million years.'

So, even though the record does not show slow, gradualistic changes, it means nothing.

In this context, it is easy to see why your falsification example fails.  Such a thing would just call for a revision in the cladogram.  No more.  Oh, of course there would be much weeping and gnashing of teeth.  Then the evolutionists would get their heads again and form another synthesis at the most.  More likely, just a new view on how exactly things evolved, not on whether or not they actually did.

There are lots of examples of this.

"First of all, linguistics is a cognitive science, and we do employ empirical techniques in the study of language."

Excellent.  Then you won't have any trouble allowing that the techniques used in paleography, textual criticism and analysis, and translation, are also often 'empirical techniques.'  It so happens that I have training in these, too.  But I guess only you get to be the scientist, right?  Not me?

"However, I'm not making the comment as a scientist, but as someone who understands scientific methodology. If you can find a bona fide scientist to back up your methodology, I will concede your point."

And what constitutes a 'bona fide scientist' ?  In my conversations with InCognito of late, I pointed out that my statements are often paralleled by the likes of Michael Denton.  Cog's response was to dismiss Denton based on Denton's existence within a small representatitve body.  To Broken I pointed out that William Purves said one thing about transposable elements in a college level biology text book, and this meant nothing- he punted it to a graduate level text book on TEs.  How do I interpret this behavior?

'Bona fide'='people who agree with me.'

I present something you don't agree with, they ain't bona fide.  Right?

"although I fail to see how that would help your case."

You've already conceded my point:

"A doctor would not have any reason to apply evolution theory directly in anything he does."

""Let's put this to the test. How does evolution factor into our understanding of the Golgi Apparatus and how it works etc, in such a way that without the TOE it would be impossible to understand?""

"Straw man. I'm not saying that biology would be IMPOSSIBLE to understand without evolution theory. In principle, some other explanation might work better. We just have none. Since you are interested in how evolution might explain the Golgi complex, I can only recommend that you google "golgi" and "evolution". You'll come up with plenty of links."

But 'evolution of the golgi apparatus' only gives you three click here

Fine, strike the word impossible.  Tell me how the theory of evolution informs us dramatically and powerfully about the GA in any way that Doctors would struggle without it.  Or even biologists, for that matter.

"Why would I need anything else, Sir Black Knight?"

The difference is that you've only cut off a hair, and it was a hair I was willing to part with.

Come on, Cop.  Let's go.  Let's rumble.  Let's explore the practical implications of evolution in the places where it matters- where lives are on the line, or... money.

We can start with the GA.  I'm not asking you to tell me how it evolved, a question that is interesting in its own right.  I'm only asking you to tell me how evolution informs our understanding of the GA in any practical way.

Should be easy. Google:  "Evolution of the Golgi Apparatus"  or
"Evolutionary implications of the Golgi Apparatus"  or "evolution informs our understanding of golgi apparatus"

Remember.  The goal is not to show theoretical implications, but PRACTICAL implications.  Ready, set, GO!

Oh yea, and one of the biochemists I chatted with worked for a major pharmacuetical company designing drugs.

I guess your 'antibiotic' example isn't as powerful as you think.  If anyone would have known, it would have been him.

Also:

"which was that a mixed rock stratum of the sort I described would be considered a shocking disconfirmation of evolution theory, since it would undermine one of the cornerstones of evidence for that theory."

Shows that the theory of evolution cannot stand on its own as a biological theory.  It requires an appeal to geology.

How would it be falsified on purely biological grounds?

"You conflated 'critical thinking' and 'science,' and I reacted to it. Thus, my remarks that science- true science- has limits on what it can say."

No, I didn't. What I wrote was "Once you learn how to think critically, then you'll be in a position to evaluate the scientific enterprise."

In what way does that conflate critical thinking and science?

Critical thinking is an element of the methodologies of science, that is all. Critical thinking is not science. Thus, when you attack science for its inability to write a love poem, you attack a strawman of your own construction.

My point is that it is much more important to learn to think critically than it is to know every jot and tittle about the modern synthesis (unless perhaps one plans to pursue a career in the life sciences).

It is more important to understand the methodologies of science and to determine whether those methodologies are likely to result in reliable conclusions that it is to understand in painstaking depth every scientific nuance in the argument itself that led to those conclusions.

Again, make no mistake about this: As part of our general education, we should all learn the basic science and argument that undergird the major theories of science. But to try to understand each of those theories at the same level of proficiency that those theories are understood by extremely bright people who have devoted their entire lives to those projects is a colossal waste of time and energy.

To reiterate: One should first determine whether the conclusions reached by the methodologies of science are reliable. If those methodologies are determined to result in conclusions that are reliable, then all else being equal, those conclusions should be believed to be reliable.

Do this and there is no need to waste valuable time in investigating every "possibly" true countercharge that some religious nut makes in opposition to some theory of science that, oh BTW, just so happens to run contrary to his faith.

"No, I didn't. What I wrote was "Once you learn how to think critically, then you'll be in a position to evaluate the scientific enterprise."

Right.  And I only reacted to a similar grouping.  If you didn't conflate, I didn't conflate.

"Thus, when you attack science for its inability to write a love poem, you attack a strawman of your own construction."

That's silly.  First of all, it wasn't an attack on science.  It was a simple statement of fact.  Secondly, it wasn't at all related to 'critical thinking.'  The point was clear and straight-forward:  science does not have the capacity to answer every question, leastwise some questions of great importance.

When you finally get around to posting the full context of Popper's essay we might get a glimpse into some of the same material.

"is a colossal waste of time and energy."

Float your own boat.  I guess the Renaissance Man is dead, eh?  

"Do this and there is no need to waste valuable time in investigating every "possibly" true"

Right.  Of course, there is a big question about what what is worth delving into deeper, and we are being left just with your opinion on what things we should dig deeper into.  Incidentally, you seem to think we should be convinced that YOUR perspective is completely reasonable.  DT is not allowed to have his own opinion.  Plus, you frame the whole enterprise in a way that begs the question to, assuming in advance that 'scientific methodologies' are superior.  However, you are on the record as saying that by 'scientific methodology' you specifically mean naturalistic, reductionist, methodologies.  That's all fine and dandy unless the question itself is "Should we restrict ourselves to views about the world that are derived strictly from reductionist, naturalistic methodologies?"

How do you answer that question without assuming in advance that it is true?  Answer:  You don't.  For all your jazz about critical thinking and your quick backpedal to include assumption evaluation, you seem to think that this extremely important assumption requires no evaluation at all.  Its not even worth examining.  We... or, I should say, DT, should just take it.

Don't worry, DT.  Cogito is going to do all the thinking for you.  He's got a metaphysical programme laid out for you.  He'll wipe your butt for you, too, if you want.   :roll:

Quote from: sntjohnny
"Your vague handwaving reference does not affect my point, which was that a mixed rock stratum of the sort I described would be considered a shocking disconfirmation of evolution theory, since it would undermine one of the cornerstones of evidence for that theory."

No, it really wouldn't.  Take punctuated equilbrium, for example...


Oh, let's not go over that many-times-refuted argument again.  You know from previous exchanges that such periods are easily explained as post-extinction periods when biological diversity explodes to fill ecological niches.  Such periods were not inconsistent with Darwin, and he even anticipated them.  Argumentum ad nauseam.  

Quote
"First of all, linguistics is a cognitive science, and we do employ empirical techniques in the study of language."

Excellent.  Then you won't have any trouble allowing that the techniques used in paleography, textual criticism and analysis, and translation, are also often 'empirical techniques.'  It so happens that I have training in these, too.  But I guess only you get to be the scientist, right?  Not me?


I doubt that you would qualify as a cognitive scientist, but that is of little matter.  One can study writing, text, and translation empirically.  As I've said before, this is about what science is, not who has credentials as a scientist.

Quote
"However, I'm not making the comment as a scientist, but as someone who understands scientific methodology. If you can find a bona fide scientist to back up your methodology, I will concede your point."

And what constitutes a 'bona fide scientist' ?  In my conversations with InCognito of late, I pointed out that my statements are often paralleled by the likes of Michael Denton.  Cog's response was to dismiss Denton based on Denton's existence within a small representatitve body.  To Broken I pointed out that William Purves said one thing about transposable elements in a college level biology text book, and this meant nothing- he punted it to a graduate level text book on TEs.  How do I interpret this behavior?


What is your point in going on about this?  Are you trying to say that your anecdotal survey was scientific?  Is that what all of this defensive posturing is about?

Quote
Fine, strike the word impossible.  Tell me how the theory of evolution informs us dramatically and powerfully about the GA in any way that Doctors would struggle without it.  Or even biologists, for that matter.


I don't see the point of this line of argument.  Doctors don't deal with evolution theory, because they are applied scientists, not research scientists.  Evolution informs scientists about every aspect of biological organisms, not just the Golgi complex.  Why are you fixated on that?  Is this something that is a theme in creationist attacks on evolution theory?  I'm not sure why you are pursuing this issue.

Quote
Come on, Cop.  Let's go.  Let's rumble.  Let's explore the practical implications of evolution in the places where it matters- where lives are on the line, or... money.

We can start with the GA.  I'm not asking you to tell me how it evolved, a question that is interesting in its own right.  I'm only asking you to tell me how evolution informs our understanding of the GA in any practical way.


Again, this seems to fly off on a tangent that means nothing to me.  The theory of evolution does not hang on whether a layman can explain the Golgi complex to you.  If you think that there is some relevant issue here, then explain the relevance.

Quote
Remember.  The goal is not to show theoretical implications, but PRACTICAL implications.  Ready, set, GO!


Apparently, you have forgotten that there is a big difference between theoretical and applied science.  Engineers use scientific knowledge to build bridges.  They do not need to appeal directly to Einstein's theory of relativity, even though Einstein's theory ultimately explains why physical forces hold that bridge up.  You are barking up the wrong tree with this line of argument.

Thanks for making my point.  ;)  Everything is consistent with Darwinism.  
That's the point.

"I doubt that you would qualify as a cognitive scientist,"

Well, I personally wouldn't assert it for myself, but don't you think its a little funny how the credentials of others 'don't matter' to you only when they agree with you?   For example, as applied to yourself?   You are not a geologist, a biologist, a physicist, but you still think you are perfectly competent to hold forth on all sorts of topics.

You can continue to try to frame the argument in terms of ridiculing the position because of the credentials or lack thereof of the person, suggesting that they 'don't understand,' but the more objective reader will detect that what's really going on is not a lack of understanding, but a simple matter of disagreement.   The objective reader will be able to learn this, because it is not impossible to find highly credentialed people who say many of the same things that I do. Simple inference shows that the full weight of your argument reduces only to people you agree with, and the rest 'don't understand.'

"As I've said before, this is about what science is, not who has credentials as a scientist."

But that is not in fact your real position.  Your idea is that you are able to say what science is but the rest of us can't.  Unless we agreed with you.  Then we can.

Now, the funny thing is, I've said repeatedly that I don't give a pile of dung about what anyone thinks about 'science.'  Unlike atheists, I understand that groups are allowed to define themselves.  Atheists, of course, presume to define Christians and all their terms, and know more about their positions, etc, etc.  That's not the way I operate.  I think Christians should have latitude to define the things they are most familiar with for themselves, and then you can react to that.  Since that is true, I naturally should extend the same courtesy to the scientists. If scientists wish to define science in a certain way, I hardly care.  I distinguish my own view from theirs in order to make plain my point.  

I call myself an experimentalist for a reason.  That reason is that there are clearly differences in epistemological value for different sorts of methods for inquiry.  My aim is to make it clear which sorts of methods I consider of value in what contexts.  I don't really care if others don't want to engage in that manner of critical thinking.

But I do care that you sweep my distinction aside altogether so as to make it sound like I'm attacking 'science.'

"What is your point in going on about this? Are you trying to say that your anecdotal survey was scientific?"

Uh, no.  But your objections were that it was flawed.  Flawed how?  Flawed from a scientific POV.  How can it be flawed from an anecdotal POV?  Did I ever offer it as anything more?  You have conceded the point that that anecdotal survey was meant to convey, so its not worth dwelling on.

"I don't see the point of this line of argument."

Of course you don't.  I wouldn't expect you to.

"Evolution informs scientists about every aspect of biological organisms, not just the Golgi complex. Why are you fixated on that?"

I'm not fixated on it at all.  I have 100 more examples ready to go.  You want to have your cake and eat it, too.  You want to insist that evolution informs scientists- I believe we were talking about doctors, though, right?  people who really depend on the stuff- about biology.  Well, the GA was just one example.  I'm giving you an opportunity to show how evolution informs the biological understanding of GA.   You seem to be unable to do this, or unwilling.  My google search showed only 3 hits (and they weren't very good) suggesting any kind of way that evolutionary theory adds to our understanding of the GA.

What if I go through 100 aspects from biology without you being able to provide a single instance where evolution informs it in real life application in any meaningful way?  For that matter, in most cases, it doesn't even inform the theoretical.  It certainly did not for the GA.  How many examples do I need to produce before you concede that perhaps evolution isn't really as necessary to understand biology as you think?  1,000?

I am confident that I could very easily produce 10,000 examples.  Easily, but it would take some time, but easy.

"Is this something that is a theme in creationist attacks on evolution theory?"

I wouldn't know.  I don't read creationist literature.

"I'm not sure why you are pursuing this issue."

Hopefully you understand a bit better now.

"Apparently, you have forgotten that there is a big difference between theoretical and applied science."

Not at all.  There certainly is a direct connection between many aspects of research science and applied science.  Just not evolutionary research.

Every piece of biological data that I've come across can EASILY be understood outside the context of evolutionary theory.  So easily, in fact, that people who really spend time applying biological facts in real life and death contexts can completely ignore it.  A 'metaphysical research programme' if you will.  ;)

The only place where I've seen applied scientists actually appeal to evolutionary theory in any respect is ecology.  And even that is usually of the 'be sure to take your full course of anti-biotics' stuff.

Or, to put it back into the context of the thread, even the medical community is asked to take evolution on faith.  It informs practically nothing that they do.  Oh yea, except for the antibiotics.  Don't forget the antibiotics.

For my next example, I submit Downs Syndrome.

I submit that evolutionary theory does not inform the matter at all, but that instead it can be only be understand by the REAL underlying basis for making biology understandable:  Genetics.

You will recall that Mendel did not need evolution to understand his pea pods.

Anyway, here is a link that firmly establishes the genetic basis for understanding Downs Syndrome:

http://www.ndss.org/content.cfm?fuseaction=InfoRes.Generalarticle&article=20

I suppose if you were going to show how evolution informs this matter, and not primarily genetics, you'd want to speak specifically to the evolutionary development of the 21 chromosome.

862 hits for 'evolutionary theory"+"down's syndrome."

HERE

192,000 for "genetics"+"down's syndrome."  

HERE

I'm doing some mad googling for you to save you some time.  If you see something that would indicate that evolutionary theory informs our research into Down's Syndrome in any significant way, do let me know.

I'm just a layman, but it seems like in this example, genetics is the real framework for understanding this biological phenemona.

Wow, saint. That is amazing! That is exactly how real scientists get their information; i.e., by making silly unrelated google searches of the web.

But how did you know that?

Hmm, I wonder. . . could it be that you really are the brilliant scientist that you claim to be?

Care to deal with the content?  The contention being focused on in these examples is that biology can only be understood, fundamentally, in the light of TOE.  So far, two examples that do not have any need at all to refer to the TOE to understand the dynamics.  No evidence that even the scientists feel the need.

So, against this, all you can say is that certain evolutionary biologists say you cannot understand biology apart from evolution.  

Why do they say that?  There should be a mountain of evidence of how your average working doctors, etc, make use of evolutionary theory in any meaningful way.  Where is this evidence?

Evidence not necessary:  Evolution by faith.

Heh. William Purves book is an intro-level biology text written for High School students. Arguing that you understand biology from reading such a book is about as reasonable as arguing you understand the Bible from reading a few pages of the Gospel of John.

SJ, I have given you pages of biological phenomena which don't make sense except in terms of evolution. In fact, I have repeated many examples over and over again. You never have an answer for them except to wipe them from your mind, as if forgetting them will somehow make them go away.  

Apparently, all such examples contradicting your "faith" simply bounce off your cranium. I will repeat just a few examples so you can forget them yet again:

Does the mitochondria example ring a bell? The fact that the mitochondria in our cells reproduce like bacteria, have bacterial genomes, bacterial ribosomes, and have gene sequences closely related to certain invasive bacteria which they physically resemble is difficult to explain except by evolution. You certainly have never provided a Creationist explanation.

Or how about the broken vitamin C gene in apes and humans? The exact same gene broken in exactly the same way in exactly the same spot. How do you explain it except by common ancestors?

Also in ape and human genomes, virus genomes inserted in exactly the same spots in our DNA. Also, the amalyse gene with a retrotransposon inserted in the very same spot in the genomes of all old world monkeys, including us. How do you explain these phenomena except by common ancestry?

There are endless other genetic examples, not to mention the entire fossil record, which have no Creationist explanation except to claim such data are not real.

I look forward to your usual dodging, followed by your usual mental deletion or denial of all information contradicting your view of reality.
