Okay… whatever. The temporal ‘spin’ is less important than the issue itself. Irrespective of whether or not the issue was ever properly laid to
rest or if it’s revived the issue DOES exist and we’re here discussing it.
I see, the idea on its own informs one some characteristics of the designer, ie that it was intelligent, but not much else.
Hmmm… I don’t see why this is so difficult for people. It’s an origins hypothesis. It assumes only one thing at it’s essence:
some aspects
of the existing universe are best explained by an intelligent cause. With respect to biological origins: It is an attempt to address some of the
major issues surrounding origins biology from an alternative perspective. Science is about hypothesis formation and test, not about one’s
metaphysical presuppositions.
Tho I think a logical conclusion of the whole thing is that the ultimate designer must be supernatural no?
Yes, you and I have had this discussion, and I did concede this to you. Irrespective of whether or not ET’s are even capable of designing complex
systems is irrelevant. At some point ET’s would have had to have been created by some seemingly supernatural ‘force’ for lack of a better
explanation. Now, I don’t care to turn this into a theological discussion, but that ‘force’ wouldn’t necessarily have to be a ‘personal’
God, as would be assumed by most monotheists. There certainly exists the Brahmain (sp?) perspective and probably other similar perspectives. But I
digress…
Yes, I concede this: IMO, ID DOES in fact rely on the presence of some ‘supernatural’ force.
But this doesn’t change the fundamental issue of
not being able to comment on the nature of the designer. I don’t see why this is an
issue. IDT still functions within the realm of
methodological naturalism irrespective of its
metaphysical presuppositions.
Does this not affect the scientific 'status' of the theory, because ultimately it appeals to the supernatural?
Absolutely not. Please see my above rebuttal involving the distinction between methodological and metaphysical naturalism.
Considering that 'natural selection' might similarly be taken to 'logically conclude' that there is no metaphysical involvment?
Actually, I disagree with statement… I think. If what you’re saying is ID and NDT (NDT, not Natural Selection, IDT has NO issue with NS) are more
or less similar because the metaphysical presupposition doesn’t affect the outcome, then I disagree. NDT assumes that there in fact
IS a
naturalistic explanation for origins. Orgel has stated something along the line of it’s not a question of if there is a naturalistic explanation,
it’s a matter of which explanation is correct. That’s a pretty frickin’ big assumption, especially coming from a leader in a field that in the
opinion of many, hasn’t produced anything approaching a reasonable hypothesis re: origins.
As I mentioned in an earlier reply in this same thread, I personally think of IDT as a lack of a metaphysical presupposition: Maybe there is a
naturalistic explanation, and maybe there isn’t. Many people doubt it. But, NO ONE, including the Creation Scientists think origins biology, or
origins science in general should cease… Everyone from the evolutionists to the YEC’s are interested in performing science that might help clarify
the answer.
Why is this inherently bad ?
If an origins hypothesis is capable of operating within the realm of methodological naturalism, it shouldn’t be excluded and misrepresented simply
because people find it distasteful.

Ahhh yes… now we get into the essence of the argument. Please note the bolded text in your quote from above. IDTist’s have not in fact,
“appealed to non-naturalistic methods.” I grant you the non-naturalistic metaphysical presupposition, but definitely not the non-naturalistic
methodology. This is an incredibly important distinction.
But these theories do no ultimately appeal to supernatural involvement. Irreducible Complexity is non-naturalistic because of that, and on the
other hand is also un-scientific in that it states that because no previous components can be thought of that therefore they must possibly exist.
Untrue. IC doesn’t state that “no previous components can be thought of that therefore they must [not] exist.” Obviously, IC systems can be
cobbled together slipshod any old way as
www.talkdesign.org..." target="_blank" class="postlink" rel="nofollow"> Matzke’s horrifically cobbled together piece of
garbage indicates. The point is not that they can’t be thought of, it’s that there is no evidence for them.
Perhaps, you can provide a reasonable explanation involving an NDT-like mechanism that might explain the origins of even one component of
photosynthetic apparatus of cyanobacteria. Go ahead and search TO and even PubMed till your heart’s content.
IMO, and I got my Ph.D. at pretty much the most prestigious photosynthesis research center in the entire world, there isn’t one. Perhaps it is time
we approached the problem from with a different hypothesis. What’s so horrible about this? And more importantly, how does this some how negatively
affect science as some would have us believe?

Why is Dembski’s rubric unscientific but SETI’s isn’t?

Intelligent Design and Evolution Awareness (IDEA) Club
[dembski] presented a new revised version of irreducible complexity:
• 1. Removal of one part destroys original function.
• 2. Removal of multiple parts kills system's original function
• 3. System has numerous complex interacting parts
• 4. System is minimally complex in relation to its minimal function for selective advantage. [...]
Darwin's unpayable debt was thus the fact that natural selection is incapable of producing irreducibly complex structures, as defined above.
Okay… what does Dembski’s definition of IC have to with his Rubric for detecting design… Oh yeah… I see. You’re confused. Dembski does not
detect design “by stating that he cannot see how a thing could've arisen via natural selection or reducible stages…” as you suggest.
Sigh… Of course, you’d know that if you’d actually read any of his stuff.
So… one more time: WHY is Dembski’s rubric unscientific, but SETI’s isn’t? My suggestion would be to spend $5 on amazon and actually analyze
some of his stuff for yourself. Hell, you can even sell the book back, then you’ll have invested what… $3 and several hours of your time.
Then we won’t have to spend 4 or 5 posts within a thread clarifying definitions and misconceptions.
Where is the demonstration the natural selection can't produce a thing that, when it has multiple parts removed, looses its function?
There isn’t one. In fact, I proposed just such a set of experiments that you’ve been trying to shoot down for a few posts now. In fact, I proposed
such demonstrations, and even proposed mechanisms to ensure success. I further pointed out that a test for a naturalistic definition is often a test
for IC.
So what gives? I propose more-or-less the exact set of experiments you described, and you describe them as being unrealistic or unscientific. Now a
couple of posts later you’re asking ‘Where are these experiments?’ what’s up with that?
I don't understand how it can be see as Dembski is ignoring that natural selection can make obejects that are complex,
Is Dembski ignoring this? I don’t think he is. I am less familiar with his stuff, as it’s a lot more math oriented than I care to regularly
indulge in. But Behe certainly isn’t ignoring this. Behe concedes that NS can involve complex things. Behe probably believes that the hemoglobin
system is derived from the myoglobin system. Behe and probably Dembski, don’t have a problem with NS creating complex things. The point is IC is not
complexity in general.
Let’s turn the tables for a moment: What IC system can be described as absolutely having evolved via NS? What IC system specifically are you
referring to that NS has ‘evolved?’ Could we please try to stick to concrete things, not retrodictions involving presuppositions of common
ancestry. Behe’s perspective, my perspective and your own personal perspective aside: Which IC (systems involving many cooperative, interacting, and
necessary pieces) can be said to have
been observed to have come about via natural selection?
how can we demonstrate that they aren't possessing specified complexity and irreducible complexity? Merely because of the probability of the
components forming?
Not sure if I understand your point. But I don’t see why basing inferences in part, on probability is a bad thing. Statistics obviously has its
place in science, why are Dembski’s probabilistic assumptions somehow inferior to the rest of the mathematics community?
The definitions of intelligent design theory, as those above, are meaningless, they aren't testable, they aren't refutable. An object with
specified complexity can't be said to be scientifically said to have formed from the exclusive action of an intelligent agent, that 'ontogeny'
isn't testable.
Well, we have discussed the fact that there STILL exists a fair amount of confusion in this thread re: IDT.

Man… Nygdan, I thought you were some kind of scientist. What scientist believes their experiments will work every time? I know a lot
of lab techs that expect this, and they should. Their stuff is worked out, and is not basic research. The norm for experimental science and basic
research – especially that involving new theories and ideas, is notoriously filled with failure. A buddy of mine took more than 10 years to get his
Ph.D. because it took him more than 6 to crystallize the protein… mind you this was the FIRST membrane protein to be crystallized… he toughed it
out because he had faith in his hypothesis. Science would make no real progress if it weren’t for people such as this.
Your experiments don’t work? Welcome to the world of basic research.
This is a definitional immpossibility tho, since IC structures by definition can't have been formed by anything like natural selection. The
question is whether or not the proposed structures are Irreducibly Complex, and you can only show that by showing that its immpossible for natural
selection to have made them in the first place, not that no one knows if they have been formed by natural selection.
However, again you’ve missed the point. If you can show that components of an allegedly IC system can in fact be replaced by components ‘put in
place’ by natural selection, the system is not necessarily IC. People assume the flagella was gradually improved upon over time to its optimal
state. Why not push it back to a suboptimal state and see if it can re-evolve
analogous components… not necessarily the same protein, which
you wouldn’t expect, but a new protein to replace the old. You could carry out thousands of generations in a couple of months using bacteria.
Furthermore your sample size would be… well pretty big, so it doesn’t “have to happen each time.” As you suggest.
If natural selection isn't operating by advancing fitness and adaptation then organisms like flowers would have parts that provide them with
no benefit but give a benefit to another organism.
Yeah… ummmm, I was not really interested in a specific example. I can visualize what you’re saying. The point is you can’t prove this idea. You
can’t say that something has no benefit for an organism. That’s the appeal of Darwinism isn’t it? You can in fact account for pretty much
anything… Furthermore, the notion of something providing an organism no benefit is hubris, a huge presupposition, and pretty much what many allege
ID to be, specifically, an argument from ignorance. Its like the incredibly unfortunate term 'junk DNA.' Simply because we don't understand the
purpose of something doesn't make it functionless.
A phylogeny is a hypothesis about relationships, it can be refuted by having evidence that changes the realtionship no?
No. Why is one phylogeny more appropriate than another. Why is a molecular phylogeny based on the gamma subunit of the ATP synthase more correct than
one based on cytochrome c? Why are they inferior to those based on Ribosomal proteins or RNA’s? Phylogenies either support one another, or they
don’t, but they’re not falsifiable.

If genetic change is intentionally induced in cells as a result of environmental cues, it’s time for significant modification of Darwinian
theories.
Originally posted by Nygdan
Why? An environmental condition can result in, say, the alteration of the proteins responsible for suppression and correction of mutations, and thus
result in more mutation and more chance of hitting upon a 'correct' adaptation. There is no 'intent' here tho. Its not as if the environment is
informing, in one way or another, that nylon in particular is present and then the genome computes a way to permit sections of the genome that could
be mutated to produce nylonase to now mutate.
Okay… in the case of this specific example that you’ve pulled completely out your imagination, yes you are correct.
However, I disagree with about ‘intent.’ No one implied that the environment is ‘informing that nylon is there.’ In REALITY, the environment
does however send messages of stress, ie: feast or famine, chemotaxic signals, etc., to the nucleus. The nucleus responds by altering expression
patterns. There is considerable evidence besides this example to suggest that in times of starvation and other stress, bacteria and other organisms
engage in a highly directed hypermutation of certain regions of the genome. The cell is intending to adapt the population to circumstances. I would
like to address this specific statement now:
, its not like allbugs do this
I agree, and this is an incredibly important point. The bug that this happened to in particular has a penchant for this type of activity.
P.
aeruginosa has demonstrated the ability to degrade a wide variety of xenobiotic compounds. This coupled with the fact that it can evolve its
ability from complete naivety to nylon oligomers in as little as nine days, and the fact the organism maintains plasmids that seem to be speicifically
associated with this ability suggest that this organism is ‘designed’ if you will, for just such a purpose. Could be a great model organism to
test IC hypotheses!!!
But if its just a frameshift, causing already existant material to be 'read' differently, then how could the environment be informing the
genome about anything? The environment would have to know that there are regions in the genome that could potentially produce a nylonase, and then
alter the genome to permit a frame shift in that region.
That’s absurd; the environment doesn’t have ‘know’ something. Do you have any idea how your immune system functions? Cells engage in
hypermutation of particular regions of the genome; they just keep ‘trying’ until they get to a combination that works or you die. The cell
doesn’t ‘know’ what its target is. It’s getting signals from the nucleus to engage in hypermutation of specific regions on the genome. Yes,
the cell, not the environment, ‘knows’ that there are particular regions that will produce effective antibodies when mutated. This is completely
analogous to the situation in the nylonase bug. Furthermore the bug even protects the integrity of its genome by maintaining the genes for adaptation
on plasmids. Finally, both instances are examples of environmentally induced mutation events to specific regions of an organisms genome –
extrachromosomal or not… hardly the random mutation events described by NDT.
And these particular bugs wouldn't necessarily produce some other digestive enzyme given some other substrate.
Not necessarily, but they’ve done it a bunch of times… it can breakdown numerous alkane species… naptha, of one variety or another, toluene…
probably a bunch of others, but I’m not too up on my nylonase stuff now…. that was soooo 2002
