Does a commitment to naturalism undermine rational thought and textual meaning?

1 Comment

Dr. William Lane Craig had a formal debate with an atheist philosopher named Alex Rosenberg a few months back that brought up an interesting idea. Rosenberg is a strong naturalist and he suggests all kinds of counterintuitive outworkings of naturalism in his book. Dr. Craig brought up a bunch of those strange views in his debate, and I listed them out in my summary of the debate as follows:

  1. The argument from the intentionality (aboutness) of mental states implies non-physical minds (dualism), which is incompatible with naturalism
  2. The existence of meaning in language is incompatible with naturalism, Rosenberg even says that all the sentences in his own book are meaningless
  3. The existence of truth is incompatible with naturalism
  4. The argument from moral praise and blame is incompatible with naturalism
  5. Libertarian freedom (free will) is incompatible with naturalism
  6. Purpose is incompatible with naturalism
  7. The enduring concept of self is incompatible with naturalism
  8. The experience of first-person subjectivity (“I”) is incompatible with naturalism

We are concerned with #1 and #2 in this post.

Now I was visiting my parents last week in my home town and Dad and I went to church on Sunday. He wanted to listen to some weird sing-song-voiced pastor on the drive there, but I plugged in my smartphone and we listened to these three podcasts by William Lane Craig instead.

Dr. Craig was explaining in part 3 (I think) about how he went on the offensive with the 8 points, and Dad asked me why Dr. Rosenberg wrote that if naturalism is true, then nothing written down is meaningful. He also wanted to know why Dr. Rosenberg would write a book if his worldview entailed that nothing written down is meaningful.

The solution has to do with Rosenberg’s denial of “intentionality”, which is the idea that something can be about something else. For example, I can think about what I had for breakfast today on the way to church (two apples and coffee) or I can think about the sermon today in my home church and how good it was. A naturalist believes that the whole universe is made up of pure matter alone, and matter cannot be about anything. So Rosenberg denies this common sense view of “intentionality” or “aboutness” because there is no room for it on his naturalistic / materialistic / physicalist view of reality.

Here is a post by Bill Valicella on Maverick Philosopher blog that answers Dad’s questions.

First, Rosenberg’s own view from his book.

A single still photograph doesn’t convey movement the way a motion picture does. Watching a sequence of slightly different photos one photo per hour, or per minute, or even one every 6 seconds won’t do it either. But looking at the right sequence of still pictures succeeding each other every one-twentieth of a second produces the illusion that the images in each still photo are moving. Increasing the rate enhances the illusion, though beyond a certain rate the illusion gets no better for creatures like us. But it’s still an illusion. There is noting to it but the succession of still pictures. That’s how movies perpetrate their illusion. The large set of still pictures is organized together in a way that produces in creatures like us the illusion that the images are moving. In creatures with different brains and eyes, ones that work faster, the trick might not work. In ones that work slower, changing the still pictures at the rate of one every hour (as in time-lapse photography) could work. But there is no movement of any of the images in any of the pictures, nor does anything move from one photo onto the next. Of course, the projector is moving, and the photons are moving, and the actors were moving. But all the movement that the movie watcher detects is in the eye of the beholder. That is why the movement is illusory.

The notion that thoughts are about stuff is illusory in roughly the same way. Think of each input/output neural circuit as a single still photo. Now, put together a huge number of input/output circuits in the right way. None of them is about anything; each is just an input/output circuit firing or not. But when they act together, they “project” the illusion that there are thoughts about stuff. They do that through the behavior and the conscious experience (if any) that they produce. (Alex Rosenberg,The Atheists’ Guide to Reality: Enjoying Life Without Illusions.  The quotation was copied from here.)

And here is what Bill says about that:

Rosenberg is not saying, as an emergentist might, that the synergy of sufficiently many neural circuits gives rise to genuine object-directed thoughts.    He is saying something far worse, something literally nonsensical, namely, that the object-directed thought that thoughts are object-directed is an illusion.  The absurdity of Rosenberg’s position can be seen as follows.

  1. Either the words “The notion that thoughts are about stuff is illusory”  express a thought — the thought that there are no object-directed thoughts — or they do not.
  2. If the latter, then the words are meaningless.
  3. If the former, then the thought is either true or false.
  4. If the thought is true, then there there are no object-directed thoughts, including the one expressed by Rosenberg’s words, and so his words are once again meaningless.
  5. If the thought is false, then there are object-directed thoughts, and Rosenberg’s claim is false.

Therefore:

  • Rosenberg’s claim is either meaningless or false.  His position is self-refuting.

As for the analogy, it is perfectly hopeless, presupposing as it does genuine intrinsic intentionality.  If I am watching a movie of a man running, then I am under an illusion in that there is nothing moving on the movie screen: there is just a series of stills. But the experience I am undergoing is a perfectly good experience that exhibits genuine intrinsic intentionality: it is a visual experiencing of a man running, or to be perfectly punctilious about it: a visual experiencing AS OF a man running.  Whether or not the man depicted exists, as would be the case if the movie were a newsreel, the experience exists, and so cannot be illusory.

To understand the analogy one must understand that there are intentional experiences, experiences that take an accusative.  But if you understand that, then you ought to be able to understand that the analogy cannot be used to render intelligible how it might that it is illusory that there are intentional experiences.

What alone remains of interest here is how a seemingly intelligent fellow could adopt a position so manifestly absurd.  I suspect the answer is that he has stupefied himself  by  his blind adherence to scientistic/naturalistic ideology.

If you want to sort of double check the details, then go ahead and watch the debate or read my summary or listen to the debate audio, and then listen to Dr. Craig’s three podcasts that I linked above.

I know a lot of you are thinking right now “Hey! You cheater! That’s a presuppositional argument! You said they were bad!” Well, I didn’t say they were bad, I said that the epistemological view of presuppositionalism was bad. Presuppositional arguments are good. See below for a few posts about them. Use them all you can, but use the good scientific and historical evidence, too.

The long war: a history of the conflict between religion and science

6 Comments

Let’s start with an example of a famous battle in the long war between science and religion.

Canadian science writer Denyse O’Leary writes about the history of cosmology at Evolution News.

Excerpt:

What help has materialism been in understanding the universe’s beginnings?

Many in cosmology have never made any secret of their dislike of the Big Bang, the generally accepted start to our universe first suggested by Belgian priest Georges Lemaître (1894-1966).

On the face of it, that is odd. The theory accounts well enough for the evidence. Nothing ever completely accounts for all the evidence, of course, because evidence is always changing a bit. But the Big Bang has enabled accurate prediction.

In which case, its hostile reception might surprise you. British astronomer Fred Hoyle (1915-2001) gave the theory its name in one of his papers — as a joke. Another noted astronomer, Arthur Eddington (1882-1944), exclaimed in 1933, “I feel almost an indignation that anyone should believe in it — except myself.” Why? Because “The beginning seems to present insuperable difficulties unless we agree to look on it as frankly supernatural.”

One team of astrophysicists (1973) opined that it “involves a certain metaphysical aspect which may be either appealing or revolting.” Robert Jastrow (1925-2008), head of NASA’s Goddard Institute for Space Studies, initially remarked, “On both scientific and philosophical grounds, the concept of an eternal Universe seems more acceptable than the concept of a transient Universe that springs into being suddenly, and then fades slowly into darkness.” And Templeton Prize winner (2011) Martin Rees recalls his mentor Dennis Sciama’s dogged commitment to an eternal universe, no-Big Bang model:

For him, as for its inventors, it had a deep philosophical appeal — the universe existed, from everlasting to everlasting, in a uniquely self-consistent state. When conflicting evidence emerged, Sciama therefore sought a loophole (even an unlikely seeming one) rather as a defense lawyer clutches at any argument to rebut the prosecution case.

Evidence forced theorists to abandon their preferred eternal-universe model. From the mid 1940s, Hoyle attempted to disprove the theory he named. Until 1964, when his preferred theory, the Steady State, lost an evidence test.

Here is a a quick summary of some of the experimental evidence that emerged in the last few decades that caused naturalists to abandon the eternal universe that they loved so much when they were younger.

The importance of having a narrative

Now I want to make a very, very important point about Christianity and the progress of science. And that point is that it is very important that Christians present the evidence in exactly the way that Denyse presented it in that article – in its historical context, featuring the conflict between naturalists and the experimental evidence.

All Christians should be familiar with the following basic pieces of evidence which fit the war between science and naturalism narrative:

  1. The origin of the universe
  2. The cosmic fine-tuning
  3. The origin of life (biological information)
  4. The sudden origin of the Cambrian phyla
  5. The habitability/observability correlation

When you talk about these evidences as a Christian theist to non-Christians, you have to have cultivated a genuine interest in reconciling your beliefs with science. You have to accept that there are two books that reveal God’s character and attributes. The book of nature, and the book of Scripture. And you need to be flexible about getting these two books to fit together. The book of nature gives us natural theology (see Romans 1). It tells us that God is Creator and Designer. The book of Scripture tells us that God stepped into history as a man to save us by taking the punishment for our headlong rush away from God, which the Bible calls sin. Science is one way that humans can recover some of basic knowledge about God. Knowledge that is only possible because God created and designed the universe (and us) in such a way that we are capable of making discoveries, and that the universe is capable of being explored and understood.

It’s very important to present these five basic evidences to non-Christians in the historical context. And here is the story you must tell: “In the beginning, there was the naturalism, and the naturalism tried to argue from ignorance that God was not Creator and God was not Designer. And then came the science, and now people have to give up their naturalism in order to not be crazy and irrational”. That’s the narrative you use when talking to non-Christians about science.

In the beginning was the naturalism:

  1. In pre-scientific times, atheists maintained that the universe was eternal
  2. In pre-scientific times, atheists maintained that a life-permitting universe was as likely as a life-prohibiting universe
  3. In pre-scientific times, atheists maintained that the cell was a simple blob of jello that could spontaneously emerge in some warm pond
  4. In pre-scientific times, atheists maintained that the sudden origin of the Cambrian phyla would be explained by subsequent fossil discoveries
  5. In pre-scientific times, atheists maintained that there was nothing special about our galaxy, solar system, planet or moon

But then science progressed by doing experiments and making observations:

  1. Scientists discovered redshift and the cosmic microwave background radiation and more!
  2. Scientists discovered the fine-tuning of gravity and of the cosmological constant and more!
  3. Scientists discovered protein sequencing and exposed the myth of “junk DNA” and more!
  4. Scientists discovered an even shorter Cambrian explosion period and the absence of precursor fossils and more!
  5. Scientists discovered galactic habitable zones and circumstellar habitable zones and more!

And now rational people – people who want to have true beliefs about reality – need to abandon a false religion (naturalism).

Now naturally, science is in a state of flux and things change. But you have to look at the trend of discoveries, and those trends are clearly going against naturalism, and in favor of Christian theism. No one is arguing for a deductive proof here, we are simply looking at the evidence we have today and proportioning our belief to the concrete evidence we have today. People who are guided by reason should not seek to construct a worldview by leveraging speculations about future discoveries and mere possibilities. We should instead believe what is more probable than not. That’s what a rational seeker of truth ought to do. Proportion belief to probabilities based on current, concrete knowledge.

It is very important that Christians keep abreast of the progress of science, and give proper respect to science when forming our worldviews, and keep in mind what is really going on with atheism. There is a lot of loud worshiping of science by people like Dawkins and Atkins and Krauss, but if you dig into things a little, you’ll find that they are actually filled with rage and enmity against what science has revealed about nature. And not just in one area, but in many, many areas.

Atheism, as a worldview, is not rooted in an honest assessment about what science tells us about reality. Atheism is rooted in a religion: naturalism. And the troubling thing we learn from looking at the history of science is that this religion of naturalism is insulated from correction from the progress of science. Nothing that science reveals about nature seems to be able to put a dent in the religion of naturalism, at least for most atheists. Their belief in naturalism is so strong that it repels all scientific evidence that falsifies it. Atheists simply don’t let science inform and correct their worldview.

It falls to us Christian theists, then, to hold them accountable for their abuse and misrepresentation of science. And that means telling the story of the progress of science accurately, and accurately calling out the religion of naturalism for what it is – a religion rooted in blind faith and ignorance that has been repeatedly and convincingly falsified by the progress of science in the modern era.

William Lane Craig debates Victor Stenger: Does God Exist?

1 Comment

This debate took place on March 1, 2010 at Oregon State University.

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”
