Is the argument for intelligent design based on ignorance?

1 Comment

From Uncommon Descent. (IC = irreducible complexity, FSCI = functional specific complex information)

Excerpt:

First, ID is not, as its opponents suggest, a purely negative argument that material forces are insufficient to account for IC and FSCI.  At its root ID is an abductive conclusion (i.e., inference to best explanation) concerning the data.  This conclusion may be stated in summary as follows:

1.  Living things display IC and FSCI.

2.  Material forces have never been shown to produce IC and FSCI.

3.  Intelligent agents routinely produce IC and FSCI.

4.  Therefore, based on the evidence that we have in front of us, the best explanation for the presence of IC and FSCI in living things is that they are the result of acts of an intelligent agent.

The second reason the “argument from ignorance” objection fails is that the naysayers’ assertion that ID depends on an “absence of evidence” is simply false.  In fact, ID rests on evidence of absence.  In his Introduction to Logic Irving Marmer Copi writes of evidence of absence as follows:

In some circumstances it can be safely assumed that if a certain event had occurred, evidence of it could be discovered by qualified investigators. In such circumstances it is perfectly reasonable to take the absence of proof of its occurrence as positive proof of its non-occurrence.

How does this apply to the Neo-Darwinian claim that undirected material forces can produce IC and FSCI?  Charles Darwin published Origin of Species in 1859.  In the 152 years since that time literally tens of thousands of highly qualified investigators have worked feverishly attempting to demonstrate that undirected material forces can produce IC and FSCI.  They have failed utterly.

Has there been a reasonable investigation by qualified investigators?  By any fair measure there has been.  Has that 152 year-long investigation shown how undirected material forces can account for IC or FSCI?  It has not.

Therefore, simple logic dictates that “it is perfectly reasonable to take the absence of proof” that undirected material forces can account for IC and FSCI as “positive proof of its non-occurrence.”

The argument from intelligent design is based on what we know. The hope that biological information has a naturalistic cause is based on what we don’t know. As science progresses, the evidence for intelligent causes in biology becomes more clear.

Biologist expresses doubts about the sufficiency of Darwinian mechanisms

From pro-naturalism Discover Magazine. (H/T Uncommon Descent)

Excerpt:

All scientists agree that evolution has occurred… The question is, is natural selection enough to explain evolution? … This is the problem I have with neo-Darwinists: They teach that what is generating novelty is the accumulation of random mutations in DNA, in a direction set by natural selection… Natural selection eliminates and maybe maintains, but it doesn’t create. …

I was taught over and over again that the accumulation of random mutations led to evolutionary change — led to new species. I believed it until I looked for evidence. …
There is no gradualism in the fossil record… ‘Punctuated equilibrium’ was invented to describe the discontinuity. …
The critics, including the creationist critics, are right about their criticism. It’s just that they’ve got nothing to offer but intelligent design or ‘God did it.’ They have no alternatives that are scientific. …

The evolutionary biologists believe the evolutionary pattern is a tree. It’s not. The evolutionary pattern is a web… [emphasis added].

(I took this extract verbatim from Jonathan’s post in Uncommon Descent, with his emphasis)

Margulis is a naturalist who believes in a naturalistic chain of causation from particles to people. But she is honest about the sufficiency of Darwinian mechanisms to explain ALL of the history of life. Maybe Darwinism isn’t the whole story. It’s part of the story for sure (micro-evolution), and there may even be common descent to some degree. But is it the whole story? Why aren’t we allowed to ask that question?

If all naturalists did was teach the evidence for and against evolution, instead of presenting as fact and brooking no scientific dissent, then I would not be so hostile to the public schools. So long as the public schools promote indoctrination instead of investigation, I will urge everyone I know to avoid them and to defund them as much as possible. The classroom is not the place for secular leftists to indoctrinate children in the religion of naturalism. They should teach what science and show, and allow discussion of alternative explanations, including the explanation of intelligent causation.

Is common descent supported by evidence from biogeography?

Just FYI, I am delaying my mean anti-feminist post until 6 PM at least to check it over.

Mysterious Jonathan writing at Uncommon Descent.

Here’s his thesis:

Recently on this blog, I have been exploring and examining some of the genomic arguments for common descent. As I have been documenting in recent weeks, while the case for common ancestry — on the face of it — looks mightily strong, closer inspection reveals that the arguments don’t, in fact, stand up under more rigorous scrutiny. In the vast majority of instances, the corroborative data is very carefully cherry picked from the pertinent data set, and the non-congruent evidence is discarded or ignored.

And here’s a snippet:

One popular argument for common descent is the case from the discipline of biogeography — that is, the study of the geographical and historical distribution of species in relation to one another. The argument is based largely around the observation that species are related in accordance with their geographical proximity with respect to one another.

And here is the problem – this is dynamite:

So, when the biogeographical data does not accord with the predictions and expectations made by common descent, one always has ‘oceanic dispersal’ as an ad hoc fudge factor — including the rather remarkable claim that Monkeys made it across the Atlantic from Africa to South America! As Casey Luskin notes here, molecular studies claim that the South American monkeys diverged from the African monkeys around 35 million years ago. But Africa became an isolated island continent around 80 million years ago!

Apparently, monkeys rode on the back of the Flying Spaghetti Monster from Africa to South America.

I actually thought that the evidence for common descent was fairly good, because Behe accepts it and he is not a Darwinist. I didn’t like it, but facts are facts. But I’m glad that Jonathan is shedding some light on this issue. I would like to be able to argue against it, if the evidence is there.
