Re: Why you shouldn't trust Philip Johnson
Well that's a very long post that manages to say almost nothing of relevance. None of it manages to dispute the fact that the pepperred moth case is evidence for natural selection and therefore for evolution.
The point under discussion is Johnson's assertion (as paraphrased by you)
Because "evolution" means so many different things, almost any example will do. The trick is always to prove one of the modest meanings of the term, and treat it as a proof of the complete evolutionary system.
So your claim that Johnson was

Obviously does not apply to the material under discussion which includes no questions at all.

Re: Why you shouldn't trust Philip Johnson
quote:
It manages to distinguish between the fact that the observed pepperred moth case being considered evidence for natural selection is not also considered a fact for evidence for the grander claims of evolution, such as common ancestry from primordial organmisms.
i.e. having established that my claim is correct YOU introduce what might be considered a "different definition" of evolution in Johnson's sense. In other words YOU are using Johnson's trick.
quote:
ok. He was making some honest statements.
Where's the honesty in misrepresentation and false accusations ?
quote:
As Raymond G. Bohlin, Ph.D. notes, primarily through his study of evolution, Johnson learned that the academic community's primary intellectual commitment is to the philosophy of naturalism. If the "facts" contradict materialistic conclusions, then the "facts" are either explained away, ignored, or just plain wrong.
Well Bohlin WOULD agree with Johnson - but that wouldn't make it true. There are plenty of Christians who support evolution against Creationism and Intelligent Design. Kenneth Miller, for instance is one of the biggest critics of ID.
quote:
Therefore, evolutionists like Richard Dawkins can say things like "Biology is the study of complicated things that give the appearance of having been designed for a purpose," and actually say it with a straight face. The appearance of design is an illusion, you see, because we "know" that organisms evolved and the primary reason we "know" this is because naturalistic philosophy demands it.
And how would you know that it is based on "the philosophy of materialism" rather than the FACT that evolutionary theory offers a better explanation of what we actually observe ?
quote:
Johnson's primary task seems to be continually provoking the scientific community into facing the reality of its naturalistic presuppositions. In earlier years, the scientific establishment was able to dismiss creationists and not officially respond. But when a tenured law professor from Berkeley starts messing with your head, people start answering back.
No, Johnson's primary task is to create that false impression ot muster polticial support for the ID movement
quote:
Incidently, what Johnson seems to have noticed was that both the rules of debate about the issue as well as the word evolution itself were defined in such a way as to rule out objections from the start.
Science is only about discovering naturalistic causes of phenomena, therefore arguing against the sufficiency of natural causes is not science.
Clearly false - it is easy to argue against the adequacy of known mechanisms IF YOU HAVE A CASE. Johnson doesn't. The ID movement have utterly failed to build any such case.
quote:
Also the "fact of evolution" is determined not by the usual definition of fact such as collected data or something like space travel which has been done, but as something arrived by majority vote.
Except that evolution IS based on collected data. Huge mountains of data. And ALL non-obvious theories are decided by the consensus of the scientists working in the field
quote:
Steven J. Gould said, "In science, fact can only mean 'confirmed to such a degree that it would be perverse to withhold provisional assent.'"
And Gould was describing evolution as a fact when he said that. What do you know that he didn't ? Or is it that he knew a lot more about the data supporting evolution than you do ?

If you do, then I don't think Johnson is wrong in making this
distinction.
Of course it is not direct evidence of common ancestry. And I am not aware of anyone who has suggested that it is. So where is the evidence that Johnson's accusation has any merit at all ?
quote:
Where's the honesty when someone simply avoids answering the following questions?
There's no dishonesty in pointing out that irrelevant questions are irrelevant and refusing to deal with them in this context. The honesty of asking them in this subthread is what you should be questioning.

There are also plenty of Christians who support young-earth creationism -- and that certainly wouldn't make it true either.
However the fact that there are knowledgable people who are definitely NOT materialists and yet accept evolution IS evidence against Bohlin and Johnson's assertion.
quote:
Why are you lumping my references to Bohlin and Miller into one theory when I quoted them for two distinct reasons -- or is this how proponents of evolutionary theories usually perceive data?
I didn't lump together YOUR references. I simply mentioned Miller as a Christian who accepts evolution and is prominent in opposing creationism and ID - and therefore as evidence against Bohlin.
I won't bother to ask whether the tactic of grabbing any excuse to make false attacks on opponents is typical of anti-evolutionits. I already know that it is.
quote:
I "know" this because whenever people like Dawkin's or Gould make the claims that appearance of design is an"illusion", they are revealing a naturalistic bias. This naturalstic bias is even more true whenever someone basically says that they "know" this is so because thier naturalistic philosophy demands it.
i.e. your claim of bias is based on a dislike for their conclusions. In other words it is your bias that is showing.
quote:
And maybe your perception is simply an illusion based on your own mental constructs.
See what I'm saying?
I don't really care what your "impressions" are.
Except the part you were replying to did not deal with MY impressions but the impression Johnson is trying to create.
So what you are really saying is that you don't care if what Johnson says is true or not. You're going to support it anyway.
quote:
Then why do researchers who engage in the scientific method sometimes conclude that God doesn't exist or wasn't involved via their own scientific observations?
Do they publiush such claims in the formal scientific literature ? If not your claim is irrelevant since that omission concedes that the conclusion is beyond science.
quote:
Notwithstanding this, Gould still claimed that Darwinism is "science" because of the methodology Darwin used in arriving at his conclusions. And I've never said that Gould said that Darwinism is not science for that matter. What are you getting at?
Since you didn't get it the first time the point is that Gould said that evolution was a fact, as he defined it. In the very essay you took the definition from. And yet here you are taking a position that Gould identified as "perverse". If he knew more than you on the subject how can you be so certain that Gould was wrong ?

Re: Why you shouldn't trust Philip Johnson
've not read Asimov's Guide to Science but based on Asimov's reputatin I doubt that he would make such a careless mistake as you suggest. Especially when you don't provide a reference beyond the title, suggesting that you don't have the book in front of you.
A little searching and if found a page from the ICR which indicates that Asimov specifically referred to the peperred moth as an example of evolution in action - as proof against the claim that such had not been observed.
Thr Ridley quote is shorn of context and given no reference at all. In the textbook Evolution (2nd Edition) Chapter 3 he gives several examples of variation, none of whicb is the peppered moth. One of these is the ring species of the Ensatina salamander in California, which provides strong evidence that microevolution can lead to speciation. Ultimately his argument is that there is no place in the taxonomic hierarchy where we can call a break and say that evolution cannot account for that level. So it would certainly be false to say that Ridley's argument relied on a single example or that he regarded the relatively simple colour change in the peperred moth to be adequate evidence for the extrapolation of microevolution to macroevolution.
You are right to point out that my objection to Johnson's claim was the unfounded accusation against evolutionists. And I say that he is equally to be distrusted in his claims about materialist philosophy.
Your response is that Johnson did not claim that there was a conspiracy. Well I suppose you thnk that it is all right to lie and make false accusations against people who disagree with you so long as you don't invent a conspiracy
Gould's distinction between fact and theory is fine. Your objection seems to be that he does not draw it in a place which is rhetorically convenient for you. Johnson's argument is that common descent is infereed from data rather than directly observed. However that is not sufficient to state that common descent is not a fact under Gould's definition, which you yourself quoted earlier in the thread. The argument you quote from Johnson simply dismisses the evidence without justification.
I note that you are finally trying to get specific about your mathematical points. Unfortunately we should not expect there to be detailed mathematical treatments to be inferred from fossil evidence. Whie we can measure rates of morphological change and see that they are consistent with evolution there is litttle more available. Analyses of the evidence is in better shape and we can infer relationships through the construction of cladograms. Genetic evidence taken from modern life is in even better shape - genetic "clock" evidence can be used to identify branch points in ancestry.
However we should not expect to produce long range predictions of future evolution - because evolution is dependent on the variations that become available through mutation and on a species interaction with its environment neither of which cna usefully be predicted. The best we can do is make short-range predictions about the spread of genes.
On to one more subject"

quote:

But what about the "knowledgable people" who think that Christians are basically crazy for thinking that they can reconcile evolution with any kind of benevolent God-like creative force?
What about them ? Many of their arguments work even better against creationism than they do against the forms of theistic evolution espoused by people like Miller.
Provine's argument is against Deism, not Christianity.
Simpson's quote is not relevant to Miller's position
Pearcey is an ID supporter (and, not so far as I know especially knowledgable in the relevant science) and therefore directly oppsoed to acceptance of evolution
Even if the materialists are right (and IMHO the God-concept is too slippery to be so easily caught) it is not even evidence that evolution is based on materialist philosophy - it is more loikely to be the case that it is beause materialim is true. Whereas the existence of non-materialists who accept evolution is strong evidence that any such basis is at least inobvious, even to people with a good understanding of the theory and the evidence..
(If you really want to investigate the matter I would strongly suggest reading Miller's book FInding Darwin\s God where he sets out his view.)
I also strognly suggest that you not rely on creationist and ID sources as you seem to be doing. THe Ruse quote is well-known nd he does not deny that evolution is valid science. That it is a religion to some people is not adequate to support Johnson's claim. Lewontin speaks of science's commitment to methodological, not philosphical materialism (Johnson is known for conflating the two).
Indeed it is significant that you rely entirely on quotes and opinions - not once do you actually try to make a direct case for Johnson and Bohlin's claim. Is it because there IS no case ?
quote:
Except the part you were replying to did not deal with MY impressions but the impression Johnson is trying to create.So what you are really saying is that you don't care if what Johnson says is true or not. You're going to support it anyway.
But PaulK, I've already given my own "impressions" and noted that they were worthless too. [/quote]
And there you confirm what I said. Rather than actually addressing the point I made you come out with another irrelevance. Obviously you don't care that Johnson is a dishonest propagandist and will invoke any excuse to avoid dealing with that fact.
As for your claim that everyone is "gung-ho" to ignore the theoretical issues I remind you that this sub-thread started with a message on a single point. What you actually seem to be complaining about is the failure of your attempt to bury that point under a mountain of diversion.
