Video of the Geivett/Craig vs. Dawkins/Shermer debate from Mexico

8 Comments

Here is the full debate in English if you missed it.

Doug Geivett wrote a blog post about the recent 3-on-3 debate in Mexico on “Does the universe have a purpose?”.

Usually, a debate question features one side taking the affirmative and the other side taking the negative. Here, the question for debate was “Does the universe have a purpose?”It was obvious from the correspondence I received from the debate organizers that I was to team with two individuals who agreed in taking the affirmative, and that the other three would take the negative—that is, they would deny that the universe has a purpose.

Speakers:

The three of us on the affirmative side—William Lane Craig, David Wolpe, and Doug Geivett—all believe that whether the universe has a purpose depends on whether or not God exists. So we could argue that the universe does have a purpose if God exists, even if time did not allow for detailed arguments that God in fact exists. It would be up to the others—Matt Ridley, Michael Shermer, and Richard Dawkins—to argue that the universe does not have a purpose. Presumably, they would have to include arguments that God does not exist, since that would be crucial to their claim that the universe does not have a purpose. Or, they might argue that even if God exists, the universe does not have a purpose.

Format:

Each of the six of us was allotted exactly six minutes for initial arguments. We were timed and stopped at six minutes. Strict enforcement of time limits is characteristic of debates, but not always understood by observers. I’ve noticed that some who’ve commented on the debate at various blogs have remarked that the moderator should not have interrupted debaters when they were about to make an important point. (The debate was part of a larger conference program.)

And here is a quote to make you click through and read all of Doug’s post:

Richard Dawkins is hero to many atheists today. So his participation and relation to the other two atheists deserves special notice. You’ll find that Dawkins made numerous assertions and almost no arguments. If you disagree, you should be able to reconstruct his arguments by identifying individual premises and specific conclusions. So far, those who have praised Dawkins’s performance in the debate, all of whom have been atheists themselves, have not attempted this reconstruction. I urge them to try. I will gladly address carefully reconstructed arguments in the comments section of this post. Dawkins called religious belief “pathetic” and accused Bill Craig of making an emotional argument. As I stated in my brief closing statement, it was Dawkins, more than anyone else, who made an “emotional argument.” First, he gave no arguments against the existence of God. Second, he offered no rebuttals of the arguments we presented, and third, he dismissed religious belief as pathetic without argument. If I’m wrong about any of this, I would be happy to see evidence of my error and respond to whatever arguments he did present.

I actually am not really paying much attention to this debate since I watched a little and it looked like a music video with a crazy moderator. The speakers made opening speeches of ONLY SIX MINUTES! I can’t watch a debate with speeches that short. You can’t say anything good in six minutes! But I have to post the video in case you guys are interested in it. I think what is worth your time is Doug Geivett’s summary of the debate. Doug is one of my three favorite philosophers, the others being Paul Copan and William Lane Craig.

What’s more complex? Your brain or the Internet?

2 Comments

Check it out… a new peer-reviewed paper discussed at CNET News. (H/T Darwin’s God via ECM)

Excerpt:

The human brain is truly awesome.

A typical, healthy one houses some 200 billion nerve cells, which are connected to one another via hundreds of trillions of synapses. Each synapse functions like a microprocessor, and tens of thousands of them can connect a single neuron to other nerve cells. In the cerebral cortex alone, there are roughly 125 trillion synapses, which is about how many stars fill 1,500 Milky Way galaxies.

These synapses are, of course, so tiny (less than a thousandth of a millimeter in diameter) that humans haven’t been able to see with great clarity what exactly they do and how, beyond knowing that their numbers vary over time. That is until now.

Researchers at the Stanford University School of Medicine have spent the past few years engineering a new imaging model, which they call array tomography, in conjunction with novel computational software, to stitch together image slices into a three-dimensional image that can be rotated, penetrated and navigated. Their work appears in the journal Neuron this week.

To test their model, the team took tissue samples from a mouse whose brain had been bioengineered to make larger neurons in the cerebral cortex express a fluorescent protein (found in jellyfish), making them glow yellow-green. Because of this glow, the researchers were able to see synapses against the background of neurons.

They found that the brain’s complexity is beyond anything they’d imagined, almost to the point of being beyond belief, says Stephen Smith, a professor of molecular and cellular physiology and senior author of the paper describing the study:

One synapse, by itself, is more like a microprocessor–with both memory-storage and information-processing elements–than a mere on/off switch. In fact, one synapse may contain on the order of 1,000 molecular-scale switches. A single human brain has more switches than all the computers and routers and Internet connections on Earth.

Smith adds that this gives us a glimpse into brain tissue at a level of detail never before attained: “The entire anatomical context of the synapses is preserved. You know right where each one is, and what kind it is.”

I wonder why we consider evolution to be a “done deal” when we don’t have testable Darwinian accounts for how things like this can evolve. They are making the claim that it evolved. I am asking for some evidence.

Philip E. Johnson lectures on science, evolution and religion

1 Comment

I found this fun lecture by the grandfather of the big-tent intelligent design movement, Berkeley law professor Philip E. Johnson.

I’ll bet you guys have all heard of him, but you’ve never heard him speak, right? Well, I was a young man, I used to listen to Phil’s lectures and his debates with Eugenie Scott quite a bit. This is one of my favorite lectures. Very easy to understand, and boilerplate for anything else in the origins debate. This is a great lecture – funny, engaging and useful. You will definitely listen to this lecture several times if you listen to it once.

The MP3 is here. (91 minutes, 41 megabytes)

The Inherit the Wind stereotype

  • Many people get their understanding of origins by watching movies like “Inherit the Wind” (or reading science fiction)
  • The actual events of the Scopes trial are nothing like what the movie portrays
  • The law forbidding the teaching of evolution was symbolic, not meant to be enforced
  • The actual Scopes trial was a publicity stunt to attract attention to Dayton, TN to bring business to the town
  • The ACLU advertised for a teacher who would be willing to be sued
  • They found a substitute physical education teacher who would be willing to “break” the law
  • The movie is nothing like the actual events the movie is a morality play
  • The religious people are evil and stupid and ignorant and bigoted
  • The scientists and lawyers are all intelligent, romantic, and honest seekers of the truth
  • The religious people think that the Bible trumps science and science is not as reliable as the Bible
  • The movie argues that the reason why there is ANY dissent to evolution is because of Biblical fundamentalism
  • The movie presents the idea that there are no scientific problems with evolution
  • The movie says that ONLY Biblical fundamentalists who believe in 6 day, 24-hour creation doubt evolution
  • The movie says that Biblical fundamentalism are close-minded, and not open to scientific truth
  • The movie says that people who read the Bible as making factual claims are misinterpreting the Bible
  • The movie says that smart people read the Bible for comfort and feelings and arbitrary values, not for truth

Guided evolution and methodological naturalism

  • What scientists mean by evolution is that fully naturalistic, unguided, materialistic mechanisms caused the diversity of life
  • Scientists do not allow that God had any real objective effect on how life was created
  • Scientists think that nature did all the creating, and any mention of God is unnecessary opinion – God didn’t DO ANYTHING
  • Scientists operate with one overriding rule – you can only explain the physical world with physical and material causes
  • Scientists DO NOT allow that God could have done anything detectable by the sciences
  • Scientists WILL NOT consider the idea that natural, material processes might be INSUFFICIENT for explaining everything in nature
  • You cannot even ask the question about whether natural laws, matter and chance can explain something in nature
  • Intelligent causes can NEVER be the explanation for anything in nature, and you can’t even test experimentally to check that
  • Scientists ASSUME that everything can be explained with natural laws, matter and chance – no questioning of natural causes is allowed
  • Where no natural explanation of a natural phenomenon is available, scientists SPECULATE about undiscovered natural explanations
  • The assumption of naturalistic sufficiency is called “methodological naturalism”
  • To question the assumptions that natural is all there is, and that nature has to do its own creating, makes you an “enemy of science”
  • But Johnson says that naturalists are the enemies of science, because they are like the Biblical fundamentalists
  • Naturalists have a presumption that prevents them from being willing to follow the evidence where it is leading
  • Experiments are not even needed, because the presumption of naturalism overrides any experimental finding that falsifies the sufficiency of natural causes to explain some natural phenomenon

What can natural selection and mutation actually do?

  • what evolution has actually been observed to do is explain changing populations of moths and finches
  • finches with smaller or larger beaks are observed to have differential survival rates when there are droughts or floods
  • no new body plan or new organ type has been observed to emerge from these environmental pressures
  • the only kind of evolution that has been observed is evolution within types – no new genetic instructions are created
  • in textbooks, only confirming examples are presented – but what is required is a broad pattern of gradual development of species
  • if you look at the fossil record, what you see in most cases is variation within types based on changing environments
  • the real question is: can natural law and chance be observed to be doing any creating of body plans and organ types?

What kind of effect requires an intelligent cause?

  • the thing to be explained in the history of life is the functional information sequences
  • you need to have a sequence of symbols or characters that is sufficiently long
  • your long sequence of characters has to be sequenced in the right order to have biological function
  • the only thing that can create long sequences of functional information is an intelligent cause
  • intelligent design people accept micro-evolution – changes within types – because that’s been observed
  • the real thing to be explained is the first living cell’s functional information, and the creation of new function information

Critical response

The next 15 minutes of the lecture contain a critical response from a philosophy professor who thinks that there have been no developments in design arguments since Aquinas and Paley. He basically confirms the stereotypes that Johnson outlined in the first part of the lecture. I recommend listening to this, because it shows how weak the counter arguments are, and how these pseudo-intellectuals mislead unprepared students to question their Christian faith – especially dangerous since they have the power of the grading pen. Notice especially how he never mentions any arguments that Christians actually use, nor does he mention any actual science. Everything is “words, words, words” as Hamlet might say – no talking about experiments.

Here’s what he says:

1) Don’t take the Bible literally, even if the genre is propositional.

  • all opposition to evolution is based on an ignorant, fundamentalist, literal reading of the Bible
  • Christians need to reinterpret the Bible so that it is basically relaying personal preferences, and not factual information, regardless of the genre intended
  • the Bible really doesn’t communicate anything about the way the world really is
  • the Bible is just meant to suggest certain opinions and experiences which you may find fetching, or not, depending on your feelings and community
  • if Christians would just interpret the Bible as myths and opinions on par with other personal preferences, then evolution is no threat to religious belief

2) As long as you treat the design argument as divorced from evidence, it’s not very effective

  • the latest and best version of the design argument is Paley’s argument which involves no experimental data, so I’ll critique that
  • this 200-year old argument which doesn’t rely on science has serious problems, and unnamed Christians agree with me!
  • Christians should NOT try to prove God’s existence using evidence from the natural world (as Romans 1 says), and in fact it’s “Pelagianism” to even try
  • Christians should divorce their faith from logic and evidence even though the Bible says that Jesus performed miracles to supply evidence for his claims
  • Christians should not tie their faith to the best science available today, because science is always changing – what happens if we discover that the universe is eternal tomorrow?
  • What if! What if! Just because you guys have the facts on your side today, tomorrow science might prove that the universe is eternal! What would you do then?
  • It’s a good idea for me to critique the arguments of 1000-year old people who did not know anything about the cosmic fine-tuning argument – that’s fair!
  • I find it very useful to tell people that the argument from design is false without mentioning any scientific evidence of design from things like DNA and fine-tuning
  • We need to assume that the natural world is explainable using only natural causes
  • We should assume that natural causes create all life, and then rule out all experimental evidence for intelligent causes that we have today
  • As long as you accept that God is a personal opinion that has nothing to do with reality, then you can do science
  • The non-Christian process theologian Teilhard de Chardin is actually a Christian, and he accepts evolution, so quit complaining you ignorant fundies!
  • Remember when theists said God caused thunder because he was bowling in the clouds and then we found out he didn’t? Yeah well – maybe tomorrow we’ll find out that functional sequences of amino acids and proteins have natural causes! What would you do then?

3) What the Bible really says is that you should vote Democrat and allow government to redistribute wealth to the poor

  • Stop thinking about creation and start thinking about social justice! But not for stinky unborn babies

Q&A time

The lecture concludes with 13 minutes of questions.
