…integrating Christian faith and knowledge in the public square

Blake Giunta and Justin Schieber debate Christian theism vs naturalism

Here is the video of the debate:

And Blake’s summary of the debate from his TreeSearch.org web site.

In Justin’s opening statement, he made four arguments:

  1. The existence of rational unbelief is more consistent with naturalism
  2. Darwinian evolution is more consistent with naturalism
  3. The hostility to life in most of the universe is is more consistent with naturalism
  4. The existence of suffering among sentient beings is more consistent with naturalism

These are all good arguments for naturalism. That’s what atheists argue if they are willing to bear the burden of proof – those are quality arguments.

In Blake’s opening statement, he made three arguments:

  1. The existence of “the moral arena” is more consistent with theism
  2. The intelligibility and discoverability of the universe is more consistent with theism
  3. The historicity of the resurrection of Jesus is more consistent with theism

These arguments are also good arguments for theism and the last one is good for Christian theism. Again, quality arguments.

Here’s part of his summary of his first argument, which I think is different from anyone else:

The Moral Arena is very unexpected if Naturalism is true

By contrast, on naturalism, a Moral Arena could not be more unexpected.

Getting brains

(a) A Universe is entirely unexpected,
(b) and even if there were one, the naturalist has no reason to expect that the Universe would be life-permitting (because of our “fine-tuning of physics for life” discoveries),
(c) and even if it were life-permitting, the naturalist has no reason to expected that there would be an origin of life event in it.
(d) and even if one (or more happened), the naturalist has no reason to expect that it would culminate in the existence of brains or anything that functions like a brain.

The alleged problem with this is that, it means that the likelihood of brains existing, on naturalism, are unfathomably low. Blake noted that the improbabilities of (a)-(d) could be multiplied together, and the likelihood of this chain of events assuming the truth of naturalism was well below .0000000001, just for the fine-tuning problem alone.

From there, getting consciousness

But getting such brains is not enough to get a Moral Arena. The next improbability was the brains being conscious. Once again, this could not be more unexpected on naturalism. Blake argued that consciousness is not adaptive on naturalism, because the brain is basically the machine, and consciousness was like smoke–the machine would evolve and operate the same with or without the smoke. Moreover, as a naturalist looks at the object of a brain, nothing “in it” would lead him to expect it has conscious experience, any more than looking at a star or electron would. Finally, Blake noted that many of the most prestigious naturalists argue that consciousness is not only entirely unexpected, but actually incompatible with naturalism–it has to be an illusion.

From there, getting beliefs

Blake then said, “Ok, but lets say you do get conscious brains. What is the likelihood, on naturalism, that they would also have these very particular things called beliefs?” He made the same moves: it could not be more unexpected on naturalism, and moreover some of the most prominent naturalists argue that beliefs are incompatible with naturalism. The reason is because beliefs are “about” things, but material objects (like rocks and brains) can’t be “about” anything. So beliefs are non-physical, which naturalism cannot accommodate.

From there, getting moral beliefs (for a Moral Arena)

Finally, Blake noted one more requirement: “Ok, so lets say you evolve conscious brains with beliefs, what is the likelihood that they would have moral beliefs in particular.” There is no reason to think moral beliefs, beliefs about good and evil, or right and wrong, would ever evolve twice in the entire Universe. But then why anticipate that they would have evolved even once? Again, Naturalism has no such reason. In each of these cases, all I can do is helplessly look at what has occurred, and say “oh, interesting.”

All together now

Calculating the final improbability involves multiplying the unlikelihood of brains evolving (.0000000001) with the unlikelihood of evolved brains being conscious (e.g. .01), with the unlikelihood of evolved conscious brains having beliefs (e.g. 01) with the unlikelihood of such brains having moral beliefs in particular (e.g. .5). The final probability is extraordinarily low, and insofar as moral beliefs are required for a moral arena, the likelihood of a moral arena existing on naturalism is unfathomably low (e.g. it seems like on naturalism, the likelihood of a moral arena would be far less than  .000001%), while on theism it is not nearly so low (e.g. well over a 1% likelihood, and certainly no less). By definition then, the Moral Arena is evidence for theism, and it turns out to be phenomenally strong evidence given the difference in expectations. Originally, the plan was to give Justin a sheet of paper to fill these in, so we could talk specifically about any particularly unreasonable values he assigned to these probabilities.

If you are looking for a classy, civil debate, this is the debate you are looking for. Justin is a great speaker and presented four real arguments, but I think Blake had him beat on on substance, because Justin did not respond adequately to Blake’s arguments.

One point that came up in the debate was the distinction between coarse-tuning and fine-tuning, and whether the range of possible values for the numbers in question could be infinite. Allen Hainline saw the debate live, and he wrote this blog post on that topic.

Darwinists thought whale hips were accidents of evolution, then science happened

Another win for reason in the long war between science and naturalistic philosophy.

Science Daily reports.

Excerpt:

Both whales and dolphins have pelvic (hip) bones, evolutionary remnants from when their ancestors walked on land more than 40 million years ago. Common wisdom has long held that those bones are simply vestigial, slowly withering away like tailbones on humans.

New research from USC and the Natural History Museum of Los Angeles County (NHM) flies directly in the face of that assumption, finding that not only do those pelvic bones serve a purpose — but their size and possibly shape are influenced by the forces of sexual selection.

“Everyone’s always assumed that if you gave whales and dolphins a few more million years of evolution, the pelvic bones would disappear. But it appears that’s not the case,” said Matthew Dean, assistant professor at the USC Dornsife College of Letters, Arts and Sciences, and co-corresponding author of a paper on the research that was published online by Evolution on Sept. 3.

[...]“Our research really changes the way we think about the evolution of whale pelvic bones in particular, but more generally about structures we call ‘vestigial.’ As a parallel, we are now learning that our appendix is actually quite important in several immune processes, not a functionally useless structure,” Dean said.

This is not the first time this has happened – as they said, the appendix now has known functionality.

Stephen C. Meyer and Marcus Ross lecture on the Cambrian explosion

Access Research Network is a group that produces recordings  of lectures and debates related to intelligent design. I noticed that on their Youtube channel they are releasing some of their older lectures and debates for FREE. So I decided to write a summary of one that I really like on the Cambrian explosion. This lecture features Dr. Stephen C. Meyer and Dr. Marcus Ross.

The lecture is about two hours. There are really nice slides with lots of illustrations to help you understand what the speakers are saying, even if you are not a scientist.

Here is a summary of the lecture from ARN:

The Cambrian explosion is a term often heard in origins debates, but seldom completely understood by the non-specialist. This lecture by Meyer and Ross is one of the best overviews available on the topic and clearly presents in verbal and pictorial summary the latest fossil data (including the recent finds from Chengjiang China). This lecture is based on a paper recently published by Meyer, Ross, Nelson and Chien “The Cambrian Explosion: Biology’s Big Bang” in Darwinism, Design and Public Education(2003, Michigan State University Press). This 80-page article includes 127 references and the book includes two additional appendices with 63 references documenting the current state of knowledge on the Cambrian explosion data. 

The term Cambrian explosion describes the geologically sudden appearance of animals in the fossil record during the Cambrian period of geologic time. During this event, at least nineteen, and perhaps as many as thirty-five (of forty total) phyla made their first appearance on earth. Phyla constitute the highest biological categories in the animal kingdom, with each phylum exhibiting a unique architecture, blueprint, or structural body plan. The word explosion is used to communicate that fact that these life forms appear in an exceedingly narrow window of geologic time (no more than 5 million years). If the standard earth’s history is represented as a 100 yard football field, the Cambrian explosion would represent a four inch section of that field.

For a majority of earth’s life forms to appear so abruptly is completely contrary to the predictions of Neo-Darwinian and Punctuated Equilibrium evolutionary theory, including:

  • the gradual emergence of biological complexity and the existence of numerous transitional forms leading to new phylum-level body plans;
  • small-scale morphological diversity preceding the emergence of large-scale morphological disparity; and
  • a steady increase in the morphological distance between organic forms over time and, consequently, an overall steady increase in the number of phyla over time (taking into account factors such as extinction).

After reviewing how the evidence is completely contrary to evolutionary predictions, Meyer and Ross address three common objections: 1) the artifact hypothesis: Is the Cambrian explosion real?; 2) The Vendian Radiation (a late pre-Cambrian multicellular organism); and 3) the deep divergence hypothesis.

Finally Meyer and Ross argue why design is a better scientific explanation for the Cambrian explosion. They argue that this is not an argument from ignorance, but rather the best explanation of the evidence from our knowledge base of the world. We find in the fossil record distinctive features or hallmarks of designed systems, including:

  • a quantum or discontinuous increase in specified complexity or information
  • a top-down pattern of scale diversity
  • the persistence of structural (or “morphological”) disparities between separate organizational systems; and
  • the discrete or novel organizational body plans

When we encounter objects that manifest any of these several features and we know how they arose, we invariably find that a purposeful agent or intelligent designer played a causal role in their origin.

Recorded April 24, 2004. Approximately 2 hours including audience Q&A.

You can get a DVD of the lecture and other great lectures from Access Research Network. I recommend their origin of life lectures – I have watched the ones with Dean Kenyon and Charles Thaxton probably a dozen times each. Speaking as an engineer, you never get tired of seeing engineering principles applied to questions like the origin of life.

The Cambrian explosion lecture above is a great intermediate-level lecture and will prepare you to be able to understand Dr. Meyer’s new book “Darwin’s Doubt: The Explosive Origin of Animal Life and the Case for Intelligent Design“. The Michigan State University book that Dr. Meyer mentions is called “Darwin, Design and Public Education“. That book is one of the two good collections on intelligent design published by academic university presses, the other one being from Cambridge University Press, and titled “Debating Design: From Darwin to DNA“. If you think this lecture is above your level of understanding, then be sure and check out the shorter and more up-to-date DVD “Darwin’s Dilemma“.

Shorebird’s beak inspires researchers to design new water collection strategy

The shorebird's beak is more interesting than you might think

The shorebird’s beak is more interesting than you might think

Dr. Fazale Rana of Reasons to Believe tweeted this cool example of biomimetics from Science Daily.

Excerpt:

A UT Arlington engineering professor and his doctoral student have designed a device based on a shorebird’s beak that can accumulate water collected from fog and dew.

The device could provide water in drought-stricken areas of the world or deserts around the globe.

Xin Heng… a doctoral student in Mechanical and Aerospace Engineering, and Cheng Luo, MAE professor, have made a device that can use fog and dew to collect water.

Cheng Luo, professor in the Mechanical & Aerospace Engineering Department, and Xin Heng, PhD candidate in the same College of Engineering department, published “Bioinspired Plate-Based Fog Collectors” in the Aug. 25 edition of ACS’ (American Chemical Society) Applied Materials & Interfaces journal.

The idea began when Heng saw an article that explained the physical mechanism shorebirds use to collect their food — driving food sources into their throats by opening and closing their beaks. Luo said that inspired the team to try to replicate the natural beak in the lab.

“We wanted to see if we could do that first,” Luo said. “When we made the artificial beaks, we saw that multiple water drops were transported by narrow, beak-like glass plates. That made us think of whether we could harvest the water from fog and dew.”

Their experiments were successful. They found out they could harvest about four tablespoons of water in a couple of hours from glass plates that were about 26 centimeters long by 10 centimeters wide.

Now, if we are lifting designs out of nature, then shouldn’t we give honor to God for putting the designs in there in the first place? I really think it’s important to give God credit where due for his clever designs, even if you’re not a big fan of the shorebird. I also think it’s interesting that it’s engineers who made this application of something in nature, not biologists.  Also, I feel I have to mention that the birdy is also cute, which is not insignificant, if you like birds as much as I do.

How brief was the period in which the Cambrian phyla suddenly appeared?

The Cambrian explosion refers to the sudden appearance of new body plans in the fossil record. ID proponents think that the period is between 5-10 million years at the most. Naturalists want to stretch out the period in which the body plans appear to tens of millions of years. The two sides can’t both be right. What’s the truth?

Evolution News has the answer.

Excerpt:

To establish the length of the most explosive period of innovation within the Cambrian explosion itself, Meyer cites the work of MIT geochronologist Samuel Bowring and his colleagues as well the work of another group led by Smithsonian paleontologist Douglas Erwin. The Bowring-led study showed that (in their words) “the main period of exponential diversification” within the Cambrian lasted “only 5-6 million years” (emphasis added). Meyer explains:

An analysis by MIT geochronologist Samuel Bowring has shown that the main pulse of Cambrian morphological innovation occurred in a sedimentary sequence spanning no more than 6 million years. Yet during this time representatives of at least sixteen completely novel phyla and about thirty classes first appeared in the rock record. In a more recent paper using a slightly different dating scheme, Douglas Erwin and colleagues similarly show that thirteen new phyla appear in a roughly 6-million-year window. (p. 73)

[...][T]ake a look first at the following figure that Bowring and his colleagues included in their definitive 1993 article, published in the journal Science. They use radiometric methods to date the different stages of the Cambrian period, including the crucial Tommotian and Atdabanian stages in which the greatest number of new animal phyla and classes arise. Note that the so-called Manykaian stage of the Cambrian period lasts about 10-14 million years. Note also that the main pulse of morphological innovation didn’t begin during this stage but rather during the Tommotian and Atdabanian — a period that they describe as taking between “5 to 10 million years,” and in a more detailed passage as taking about 5-6 million years.

[...]In the figure above, the Tommotian and Atdabanian stages of the Cambrian period together span only about 5 million years, starting at about 530 and ending about 525 million years ago. Bowring’s figure also depicts the total number of classes and orders present at any given time during the Cambrian period. The biggest increases in morphological innovation occur during the Tommotian and Atdabanian stages. Indeed, during this period the number of known orders nearly quadruples. Moreover, Bowring and his colleagues also make clear that this period corresponds to the main pulse of Cambrian morphological innovation as measured by the number of new phyla and classes that first appear. They note that, while a few groups of animals do arise in the earliest Manykaian stage of the Cambrian, the most rapid period of “exponential increase of diversification,” corresponding to the Tommotian and Atdabanian stages, “lasted only 5 to 6 m.y.”

You can see the figure they are reference in the Evolution News article.

Also, check out these clips that explain the Cambrian explosion:

Part 1:

Part 2:

The first clip features James Valentine, a professor of biology at the University of California who just co-authored a new book on the Cambrian explosion and is not a proponent of intelligent design.

The consensus among scientists regarding the period of time in which the new body plans appear is 5-6 million years. Biologically speaking, that’s a blink of an eye. You aren’t going that kind of complexity and innovation in such a short period of time any more than you can expect to win the lottery by buying 5-6 million tickets when the odds of winning are 1 in a googol (10 to the 100th power – 1, followed by 100 zeroes). You don’t have enough lottery tickets to make winning the lottery likely. Similarly, 5-6 million years is not enough time for naturalistic mechanisms to code brand new body plans from scratch. It would be like trying to research and write a Ph.D thesis during a single lunch hour. It’s just not enough time to produce the amount of information that’s required.
