Summary of Hitchens’ opening speech, snarkified and with spin removed

Contentions:

  1. God has to make the universe the way I would, but he didn’t.
  2. I don’t like some things that people who claim to be religious do.

Arguments from science:

The fact that our current universe is running out of usable energy (entropy) means that there is no God, because God, if he existed, would agree with me that the universe should go on forever.

The fact that the universe is a very big place means that there is no God, because God, if he existed, would agree with me that the universe should be very small.

The fact that the universe is a very old place means that there is no God, because God, if he existed, would agree with me that the universe should be very young.

The fact that the universe contains exploding stars means that there is no God, because God, if he existed, would agree with me that the universe should not contain exploding stars.

The fact that the universe is expanding means that there is no God, because God, if he existed, would agree with me that the universe should not be expanding.

The fact that the Earth is a small rock means that there is no God, because God, if he existed, would agree with me that the Earth should not be a small rock.

Arguments from history:

Although I don’t believe that there is any objective standard of right and wrong, I personally feel that Islamic terrorism is yucky yuck yuck. It’s just my opinion though, since there is no objective standard of morality on atheism, but only arbitrary personal preferences and arbitrary customs that vary by time and place. Since these Muslim terrorists claim to be acting on behalf of God, and I don’t like what they do, therefore God doesn’t exist.

Although I don’t believe that there is any objective standard of right and wrong, I personally feel that Israeli military expansion is yucky yuck yuck. It’s just my opinion though, since there is no objective standard of morality on atheism, but only arbitrary personal preferences and arbitrary customs that vary by time and place. Since these Israeli military expansionists claim to be acting on behalf of God, and I don’t like what they do, therefore God doesn’t exist.

Arguments from the human condition:

Although I said a minute ago that we should be cautious about the good experimental science that supports theism by showing that the universe came into being from nothing, fine-tuned for complex life, based on multiple lines of experimental evidence, I actually think that Darwinian evolution is true beyond a shadow of a doubt, based on ZERO lines of experimental evidence for macro-evolution (the evolution of new body plans and organ types). But since Darwinism is definitely true – as true as man-made global warming! – then God couldn’t exist. Why? Because God would not use a gradual process to create life, because I wouldn’t use a gradual process to create life. God, if he existed, would always do what I would do if I were God. Also, we are similar to chimpanzees which proves that molecules to man evolution is true. Certainly there is no peer-reviewed evidence that human and chimpanzee DNA are actually very different. (Note that the link goes to Nature, the #1 peer-reviewed science journal).

When you were in your mother’s womb, you grew some hair and then it fell off, proving there is no God, because God, if he existed, would agree with me that babies should not grow hair in their mother’s womb, only to have it fall off.

Humans have appendices that have no purpose that is apparent to me, based on my vast experience with biology gleaned from writing snarky columns. Since I don’t see a purpose to your appendix – certainly there is no peer-reviewed evidence that the appendix has any useful biological purpose – therefore God does not exist.

When you were a child, you grew some teeth and then they fell off, proving there is no God, because God, if he existed, would agree with me that children should not grow teeth, only to have them fall off.

There are a lot of species that go extinct in the history of life and this proves that there is no God, because God, if he existed, would not have wanted lots of species to go extinct.

The smart theistic evolutionist Francis Collins believes in Darwinian evolution and he’s smart. I can’t give you any reasons why he believes in Darwinian evolution right now, but you should definitely believe in evolution because of his authority and his skill at avoiding debates on evolution with his critics in the intelligent design movement.

You need to be more humble like me, you ignorant fools. If you simply read more cosmology, physics, chemistry and biology, like we clever journalists have, then you would be a smart atheist like me! And humble, too, you ignorant, illiterate fundamentalists!

Summary of Dembski’s opening speech

Contentions:

  1. Evolution is false, Hitchens’ proofs from his book don’t work.
  2. Hitchens makes historical claims that are falsified by the evidence.
  3. The progress of science falsifies atheism
  4. Theism explains the big question of life better than atheism

Darwinian evolution vs. the evidence:

Junk DNA is not junk because the latest peer-reviewed scientific evidence shows that the so-called Junk-DNA actually has important functions in the cell. (Note that the link goes to Nature, the #1 peer-reviewed science journal).

The fossil record does not show a gradual pattern of emerging body plans because the latest evidence on the Cambrian explosion shows that new body plans emerged fully-formed without gradual developmental pathways.

The inverted retina is not a bad design, the counter-intuitive design actually is superior when the latest published research is considered.

Hitchens’ argument about the evolution of the eye rely on mathematical simulations, not on experimental evidence.

Hitchens is committed to Darwinism whether there is any evidence or not, because he pre-supposes materialism, so some form of evolution MUST be true, regardless of how lousy the observable evidence is for it.

Historical arguments:

Hitchens dismisses Israel’s time in Egypt and at Mount Sinai, but the evidence is written up in books like those of James K. Hoffmeier, published by Oxford University Press.

Hitchens dismisses the historical records about Jesus, but these are again made clear in publications of top academic presses. (E.g. – N.T. Wright, Richard Bauckham, etc.)

The progress of science falsifies atheism:

Atheism requires that chemical evolution be true. Darwin thought that cells were simple because he needed them to be simple for this theory, and he didn’t know anything about what cells were really like. But the progress of science has shown that the complexity of cells is enormous.

You can actually use rigorous methods developed by Bill in his book “The Design Inference”, published by Cambridge University Press, and apply them to effects in nature, like archaeological artifacts, radio signals from space, and… cells and molecular machines.

When you apply the mathematical methods for inferring design to biology in books like “Signature in the Cell” or “The Design of Life”, components of living systems are found to be designed for a purpose.

The big questions are answered better by theism than atheism:

Other arguments: the cosmological argument, the fine-tuning argument, the moral argument, the argument from rationality/reason, the argument from mathematical foundations of reality, the argument from the the historicity of the resurrection of Jesus, etc.

Target acquisition and interception in dragonflies

Leave a comment

Here is a fascinating post about some of the capabilities of dragonflies from Evolution News.

Selective attention

First, dragonflies have “selective attention” – the ability to focus on a single prey and ignore other distractions:

Dragonflies are among the best flyers in the insect world. Their twin pairs of paper-thin wings allow them to hover and move in all directions, even in mating. When the time comes to dart after prey at high speed, they rarely miss.

What’s their secret? One is “selective attention” — a trait previously known only in primates, according to new research from the University of Adelaide, Australia. Selective attention is the ability to focus on one object and exclude others. Just as a tennis player must focus on the ball and ignore the cheers of the crowd, a dragonfly must pick out one target from a swarm of insects and avoid being distracted by all the others.

Here’s a snip from the research paper:

Our data make a compelling case that CSTMD1 reflects competitive selection of one target. We emphasize “competitive,” because the attended target is not always the same between trials or even within a trial, as seen in strikingly perfect switches from one to the other…. Competition is further suggested by rare examples where the activity observed under Pair stimulation initially lags both T1and T2 responses… suggesting initial conflict in the underlying neural network before resolution of competition by a “winning” target.

We previously showed that CSTMD1 still responds robustly to a target even when it is embedded within a high-contrast natural scene containing numerous potential distracters. Taken together with recent evidence that the behavioral state of insects strongly modulates responses of neurons involved in visuomotor control, our new data thus suggest a hitherto unexpected sophistication in higher-order control of insect visual processing, akin to selective attention in primates.Perhaps the most remarkable feature of our data is that once the response “locks” onto a target (or following a switch), the second target exerts no influence on the neuron’s response: the distracter is ignored completely.

In order to succeed at the task of catching its prey, the dragonfly has to tune out all other distractions.

Target selection

In addition, dragonflies have the ability to intercept a target in mid-air – similar missile defense systems on AEGIS cruisers and destroyers.

The Evolution News article explains:

Another paper on dragonflies shows that these marvels of the insect world are equipped with navigational equipment that can do vector calculus. In the Proceedings of the National Academy of Sciences, Gonzalez-Bellido and a team at the Howard Hughes Medical Institute discerned “Eight pairs of descending visual neurons in the dragonfly [that] give wing motor centers accurate population vector of prey direction.”

Intercepting a moving object requires prediction of its future location. This complex task has been solved by dragonflies, who intercept their prey in midair with a 95% success rate. In this study, we show that a group of 16 neurons, called target-selective descending neurons (TSDNs), code a population vector that reflects the direction of the target with high accuracy and reliability across 360°. The TSDN spatial (receptive field) and temporal (latency) properties matched the area of the retina where the prey is focused and the reaction time, respectively, during predatory flights. The directional tuning curves and morphological traits (3D tracings) for each TSDN type were consistent among animals, but spike rates were not. Our results emphasize that a successful neural circuit for target tracking and interception can be achieved with few neurons and that in dragonflies this information is relayed from the brain to the wing motor centers in population vector form.

What did I make of this? Well, evidence like this always causes me to think aboutthe reality of God, and the disturbing thought that we do not live in an accidental universe where I can do whatever I want and be accountable to no one. It’s easier to believe that – it requires less work and it frees us to be our own boss and make our happiness the first priority. As individuals, it’s very tempting for us to think that we are number one, and to resent our obligations to anyone else. The problem is that the scientific data doesn’t support that worldview. The facts are what they are and it is up to us, now, to try to find out who the designer is and what he wants from us.

William Lane Craig debates Victor Stenger: Does God Exist?

Leave a comment

Here are the details of the debate that I got from Cloud of Witnesses:

The OSU [Oregon State University] Socratic Club will sponsor a public dialogue entitled, “Two Philosophers Debate the Existence of God,” on Monday, March 1, at 7 p.m. in the LaSells Stewart Center on the OSU campus.  William Lane Craig will argue for the Christian view that a personal God exists and Victor J. Stenger the atheist position that there is no God.

In this debate, Victor Stenger does affirm his belief that the universe could be eternal in his second rebuttal (1:02:30), thus denying the standard Big Bang cosmology. He also denies the law of conservation of energy and asserts that something can come from nothing in his concluding speech (1:33:50). He also caused the audience to start laughing when he said that Jesus was not moral and supported slavery. There is almost no snark in this summary. Instead, I quoted Dr. Stenger verbatim in many places. I still think that it is very entertaining even without the snarky paraphrasing.

The debate includes 30 minutes of Q&A with the students.

Here is the MP3 file for the audio.

Here’s the video of the debate:

Dr. Craig’s opening speech:

  • The ontological argument
  • The contingency argument
  • The cosmological argument
  • The moral argument
  • The resurrection of Jesus (3-fact version)
  • Religious experience

Dr. Stenger’s opening speech:

  • There is no scientific evidence for God’s existence in the textbooks
  • There is no scientific evidence for God acting in the universe
  • God doesn’t talk to people and tell them things they couldn’t possibly know
  • The Bible says that the Earth is flat, etc.
  • There is no scientific evidence that God answers prayers
  • God doesn’t exist because people who believe in him are ignorant
  • Human life is not optimally designed and appears to be the result of a blind, ad hoc evolutionary process
  • The beginning of the universe is not ordered (low entropy) but random and chaotic
  • It’s theoretically possible that quantum tunneling explains the origin of the universe
  • The laws of physics are not objectively real, they are “our inventions”
  • Regarding the beginning of the universe, the explanation is that something came from nothing*
  • Nothing* isn’t really nothing, it is “the total chaos that we project existed just before the big bang”
  • If something has no structure, then “it is as much nothing as nothing can be”
  • Consciousness is explainable solely on the basis of material processes
  • There are well-informed, rational non-believers in the world and God would not allow that

Dr. Craig’s first rebuttal:

Stenger’s argument that there is no objective evidence for God’s existence:

  • First, it is not required that God rely only on objective evidence in order to draw people to himself (Alvin Plantinga)
  • Second, God is not required to provide evidence to everyone, only to the people who he knows would respond to him
  • Third, Craig gave lots of objective evidence, from science, history and philosophy
  • Stenger asks for certain evidence (answered prayers, prophecy, etc.), but Craig presented the evidence we have

Stenger’s argument that the balance of energy is zero so “nothing” exists:

  • if you have the same amount of assets and liabilities, it doesn’t mean that nothing exists – your assets and liabilities exist
  • Christopher Isham says that there needs to be a cause to create the positive and negative energy even if they balance
  • the quantum gravity model contradicts observations
  • the vacuum is not the same as nothing, it contains energy and matter
  • the BVG theorem proves that any universe that is expanding must have a beginning

Stenger’s argument that mental operations can be reduced to physical operations:

  • mental properties are not reducible to physical properties
  • epiphenomenalism: is incompatible with self-identity over time
  • epiphenomenalism: is incompatible with thoughts about other things
  • epiphenomenalism: is incompatible with free will
  • substance dualism (mind/body dualism) is a better explanation for our mental experience
  • God is a soul without a body
Dr. Stenger’s first rebuttal:

Craig’s cosmological argument:

  • Craig’s premise is “everything has a cause”, but quantum mechanics has causeless events
  • There are speculative theories about how something could have come into being uncaused out of nothing
  • “I don’t know of a single working cosmologist today who believes there was a singularity prior to the Big Bang”
  • “If there wasn’t a singularity then there’s no basis for arguing that time began at that point”
  • “There’s no reason from cosmology that we know of that the universe can’t be eternal”
  • “When I talk about an eternal universe, I mean a universe that has no beginning or end”
  • The Hartle-Hawking model doesn’t have a beginning
  • “There was no violation of energy conservation by having a universe coming from nothing”
  • “The universe could have come from a previous universe for example or even just from a region of chaos”
  • The paper by Vilenkin is counteracted by other papers (he doesn’t specify which ones)

Craig’s moral argument:

  • Dr. Craig is arguing from ignorance
  • But morality can be decided by humanity just like governments pass laws, and that’s objective
  • Dr. Craig has too little respect for the human intellect
  • I don’t need to tell me that slavery is wrong
  • The Bible supports slavery
  • Atheists can behave as good as theists
  • Morality just evolved naturally as an aid to survival

Craig’s resurrection argument:

  • No Roman historians wrote about the execution of Jesus but none of them did
  • The empty tomb is doubtful because it is only mentioned in the gospels, not by Paul
  • John Dominic Crossan says there was no empty tomb
  • Christianity only survived because the Roman empire thought that they were useful

Dr. Craig’s second rebuttal:

Craig’s cosmological argument:

  • There is no reason to prefer an indeterministic interpretation of quantum mechanics
  • Dr. Stenger himself wrote that deterministic interpretations of quantum mechanics are possible
  • The vacuum in quantum mechanics is not nothing
  • The quantum vacuum he proposes cannot be eternal
  • The cosmological argument does not require a singularity
  • The Hartle-Hawking model is from 1983
  • Hawking says that there is a beginning of space and time after that model
  • The Hartle-Hawking model does still have a beginning of time – the model is not eternal
  • The BVG theorem that requires a beginning for expanding universes is widely accepted among cosmologists

Craig’s moral argument:

  • Stenger redefined objective to mean that most people agree with it – but that’s not what objective means
  • Objective means right and wrong whether anyone accepts it or not
  • Richard Dawkins himself says that on atheism there is “no evil and no good” – why is he wrong?
  • Even Dr. Stenger says that morality is the same as passing laws – it’s arbitrary and varies by time and place
  • But on his view, right and wrong are the same as deciding which side of the road to drive on
  • But somethings really are right and some things are really wrong

Craig’s resurrection argument:

  • Josephus is a Roman historian and he wrote about Jesus, for example
  • There were four biographies of Jesus are the best sources for his life
  • The scholars that Stenger mentioned are on the radical fringe

Dr. Stenger’s second rebuttal:

Knowledge and the burden of proof:

  • Dr. Craig has to bear the burden of proof, not me – because his claim is more “extravagant”
  • “I don’t have to prove that a God was not necessary to create the universe”
  • “I don’t have to prove that a God did not design the universe and life”
  • “I don’t have to prove that the universe did not have a beginning”
  • “I don’t have to prove that God did not provide us with our moral sense”
  • There are a lot of books written about how morality evolved naturally
  • “I don’t have to prove that the events surrounding the supposed resurrection of Jesus did not take place”
  • Bart Ehrman says that the gospels are generally unreliable (Note: Ehrman accepts all 3 of Craig’s minimal facts)
  • Just because people are willing to die for a cause, does not make their leader God, e.g. – the Emperor of Japan

Aesthetic concerns about the universe:

  • I don’t like dark matter and I wouldn’t have made the universe with dark matter
  • I don’t like the doctrine of penal substitution
  • I don’t like the doctrine of original sin
  • I don’t like the heat death of the universe

Dr. Craig’s conclusion:

The case for atheism:

  • Dr. Stenger had two arguments and he has to support his premises
  • Dr. Craig addressed his two arguments and each premise and Dr. Stenger never came back on it

The contingency argument:

  • Dr. Stenger has dropped the refutation of this argument

The cosmological argument:

  • The theoretical vacuum he proposes cannot be eternal

The moral argument:

  • He asserts that things are wrong, but there is no grounding for that to be objective on atheism

The resurrection of Jesus:

  • There are surveys of scholars on the empty tomb and 75% of them agree with it
  • Bart Ehrman agrees with all 3 of the minimal facts that Dr. Craig presented
  • Ehrman’s objection to the resurrection is not historical: he’s an atheist – he thinks miracles are impossible

Religious experience:

  • No response from Dr. Stenger

Dr. Stenger’s conclusion

The cosmological argument:

  • “I argued that we have very good physical reasons to understand how something can come from nothing”
  • “There is a natural tendency in the universe… to go from.. simpler thing to the more complicated thing”
  • The transition from a vapor to a liquid to ice shows how something could come from nothing
  • “It cannot be proven that the universe had a beginning”

The moral argument:

  • Objective morality, which is independent of what people think, could be developed based on what people think
  • “Jesus himself was not a tremendously moral person… he had no particular regard for the poor… he certainly supported slavery… he was for the subjugation of women” (audience laughter)

The resurrection argument:

  • Bart Ehrman says that the majority of the gospels are unreliable

Religious experience:

  • I don’t see any evidence that there is anything more to religious experience than just stuff in their heads

God’s purpose of the world should be to make people feel happy:

  • God could have made people feel happier
  • God could have made people not die
  • God could could have made the universe smaller: it’s too big
  • God could have made it possible for humans to live anywhere “even in space”
