"I was describing evolution. I did not say design could not be observed."
It sure sounded as though that's what you were saying, though. See my next comment.
"However, we observe no designers of the sort hypothesized by Intelligent design."
But that's irrelevant. Similarly, you might be able to say that we observe no mechanisms of the sort hypothesized by evolution. See for example this link:
http://www.talkorigins.org/faqs/comdesc/default.html#theorytobetestedNote this statement:
Therefore, the evidence for common descent discussed here is independent of specific gradualistic explanatory mechanisms. None of the dozens of predictions directly address how macroevolution has occurred, how fins were able to develop into limbs, how the leopard got its spots, or how the vertebrate eye evolved. None of the evidence recounted here assumes that natural selection is valid. None of the evidence assumes that natural selection is sufficient for generating adaptations or the differences between species and other taxa. Because of this evidentiary independence, the validity of the macroevolutionary conclusion does not depend on whether natural selection, or the inheritance of acquired characaters, or a force vitale, or something else is the true mechanism of adaptive evolutionary change. The scientific case for common descent stands, regardless.
So really, if your charge is valid, it sticks to evolution as much as it does to ID. One can infer design without caring one lick as to who anyone might think the correct identity of that designer is.
"True. Go visit the Discovery Institute website. They maintain that the origin of life is due to an intelligent designer."
But NOT a priori. as you admit:
"IDers such as Behe maintain that the bacterial flagellum is evidence of "irreducible complexity"."
That's starting with evidence and coming to a conclusion. You can't nail a person because they have come to a conclusion, say as much, and then go in to show why they have come to that conclusion.
"The data on the precursor organism is absent. So, as I said, the IDer's use the absence of evidence as evidence."
The 'precursor organism'? That's assuming evolution. What data? Perhaps the data is 'absent' because it does not exist.
Or, perhaps it is 'absent' because it can not even possibly exist.
If it cannot even possibly exist, then it is positive evidence, not negative evidence.
Your flaw is in importing evolutionary assumptions into the subject. In this example, the flagellum is not argued because of a lack of data, but because it is argued that no such data can ever be forthcoming, period. Note, this is falsifiable in that if one actually did observe the evolution of the flagellum.
"Err, the theory is even called "Intelligent Design". An intelligent agent is the central hypothesis. If you think this agent has ever been observed, perhaps you can point me to the evidence."
No, design is the central hypothesis. The agent is inferred, and has nothing to do with whether or not the evidence points to design or not.
Surely you don't oppose to inferences in science?
"Throwing spitwads already, are we?."
?
I really wanted to know.
"Broken was the name I used on various online military-simulation game websites. A common goal is to "break" the morale of your opponents forces. Broken also means to think outside the box, as in "break" the rules. I was too lazy to change my name when I came here."
Kewl. I played rainbow 6 for awhile. I also enjoyed world war 2 online.
"I agree. ID does not BEGIN with the assumption of an intelligent designer. It claims certain biological systems could not have evolved through natural selection and that life could not have arisen on it's own. THEREFORE, say the IDers, the only explanation is an intelligent designer."
First of all, you've here given up the argument. If it does not begin with the assumption of an intelligent designer you can't argue that as much, as you did only a few paragraphs ago (See the SS Fallacy) in saying "we observe no designers of the sort hypothesized by Intelligent design"
"This is like saying: we know of no mechanism which could account for gravity, therefore it must be caused by intelligent angels."
No, this is like saying we know we evolved from a common ancestor, but we don't know how.
"There is no phenomena to suggest the existence of an intelligent designer,"
That, of course, is only your opinion.
"Because intelligent agents, and presumably the Divine Agent, have causal powers that nature does not have, intelligent design may always be a possible explanation."
And people complain about creationists taking things out of context. And you are committing another contextual blunder, too, but I will take it in your next remark. First, here is the next sentence:
"Nevertheless, possible explanations are not necessarily the best explanations."
He's not supporting your point one bit by offering ID as always being a 'possible explanation' given the fact he follows with the point that a possible explanation is not the best explanation. You could also say that naturalistic (non-agency) explanations are possible for everthing as well. Its the flipside of the same coin, with the result that the same can hold for evolution: "Possible explanations are not necessarily the best explanations."
"So Meyer is directly contradicting you: the intelligent agent has causal powers nature does not have: it is supernatural."
I did a cursory search through that document and Meyer constantly goes out of his way, when saying either 'divine agency' or 'agency' to make it clear that what he is saying can apply to both. So, he is not even close to contradicting me. He is not saying that 'the' intelligent agent has causal powers that nature does not have, and referring to, by using the word 'the' the 'divince agent.' How'd you miss it.... See if you see the same equivocation about agency and divine agency in the following sentence...
"
Because intelligent agents, and presumably the Divine Agent, have causal powers that nature does not have"
So, unless you are arguing that you and I also are 'supernatural' or think that's what he is saying, you are taking him out of context completely. He is saying that WE have causal powers that nature does not have, as well. Similarly, Francis Crick's intelligent agents he posited for his directed panspermia are not posited to have been divine agents, right? Carl Sagan's intelligent agents in "Contact" were not presumed to have been divine agents, and yet, both would be consistent with Meyer's statement about them having 'causal powers that nature does not have."
I feel..... supernatural. :)
"Fine, but then ID is no longer science. And theoretical physics hypotheses such as string theory are accepted only as hypotheses yet to be experimentally verified."
How is this view here (I didn't read Meyer any further to see if you were put him in the proper context in this case, as well) consistent with:
"I did not say design could not be observed. We are surrounded by devices of human design. We even see many examples of animal design, such as beehives, beaver-dams, and bird's nests."
Do you feel as you wander this earth that you have troubles confidently detecting design around you?
Let me offer something to you that I'm not sure how you will respond to. Let's ignore the flaws in your argument and say that design is too awfully hard to detect in a scientific manner and so cannot be really be considered science. Or whatever. Let me retort to your 'Fine' by offering my own:
Fine, if science is so limited and castrated and incompetent so as to even be able to recognize design reliably- even though you and I both know that we can reliably detect design without the aid of the scientific method (so easy, a baby can do it)- then, ok, let's not have design qualify as 'science.' I can live with that. But don't be shocked if I don't feel compelled very much to consider science to be a very robust method of discovering truth in this world if it cannot even tell me the difference between a house and a pile of lumber.
I think that's a good way of putting it. Do you think that science can be appropriately used to reliably determine whether or not a system of lumber is the product of design or not?
"No, we do not observe design except that of human or animal origin."
This is begging the question in disguise. :) What do you make of Sagan's intelligent agents? The nature of the designer can be treated separately and distinct from the identity of the designer. What do you make of Crick's intelligent agents?
