Here is the video from the third debate from Dr. William Lane Craig’s speaking tour in Australia.

Format:

  • William Lane Craig (15 min)
  • Lawrence Krauss (15 min, but was actually 21:40)
  • Moderated discussion
  • Question and answer

Dr. Graham Oppy, the moderator, is a well-known atheist philosopher. He let Dr. Krauss speak for 21 minutes and 40 seconds, which is why my summary of Krauss is so long.

The video:

Summary

After careful consideration, I decided not to be snarky at all in this summary. What you read below is what happened. There may be some small mistakes, but I will fix those if people tell me about them. I also included some quotes and timestamps for the more striking things that Dr. Krauss said.

The debate itself starts at 4:50 with Dr. Craig’s opening speech. He does use slides to show the structure of his arguments.

Dr. Craig’s opening speech. (4:50)

  1. The kalam cosmological argument:
    • God is the best explanation of the origin of the universe
    • The Borde Guth Vilenkin theorem supports the absolute beginning of the universe
    • Even if our universe is part of a multiverse, the multiverse itself would have to have an absolute beginning
    • Speculative cosmologies try to challenge the Big Bang theory, but none of them – even if true – can establish that the past is eternal
    • Only two types of things could explain the origin of spece, time, matter and energy – either abstract objects or minds
    • Abstract objects do not cause effects, but minds do cause effects (we do it ourselves)
    • A mind is the best explanation for the origin of the universe
  2. The unreasonable effectiveness of mathematics:
    • The underlying structure of nature is mathematical – mathematics is applicable to nature
    • Mathematical objects can either be abstract objects or useful fiction
    • Either way, there is no reason to expect that nature should be linked to abstract objects or fictions
    • But a divine mind that wants humans to understand nature is a better explanation for what we see
  3. The cosmic fine-tuning for the existence of intelligent life
    • There are two kinds of finely-tuned initial conditions: 1) cosmological constants and 2) quantities
    • These constants and quantities have to be set within a narrow range in order to permit intelligent life
    • There are three explanations for this observation: law, chance or design
    • Law is rejected because they are put in at the beginning or matter – they don’t emerge from matter
    • Chance must be rejected, because they odds are just too long unless you appeal to a world-ensemble
    • We do not observe what the world ensemble hypothesis predicts that we should observe
    • Design is the best explanation for finely-tuned constants and quantities
  4. The existence of objective moral values and duties
    • Our experience of morality (values and duties) is that it is objectively real and incumbent on us
    • When someone goes into a classroom and shoots at innocent children, that is objectively wrong
    • On naturalism, moral values and moral duties do not exist – they are conventional and variable by time and place
    • The best explanation for the existence of objective moral values and duties is that God exists
  5. The historicity of the resurrection of Jesus
    • There are three widely-accepted facts that are best explained by the resurrection hypothesis
    • 1) the empty tomb, 2) the post-mortem appearances, 3) the early church’s belief in the resurrection
    • Naturalistic attempts to explain these 3 boilerplate facts fail
    • The best explanation of the 3 minimal facts is that God raised Jesus from the dead
  6. The immediate experience of God
    • Belief in God is a “properly basic” belief – rational even without arguments because of experience of God

Slides: (1234567891011121314)

  1. Religious pluralism I
    • There have been lots of different gods created by people through history
    • We’ve gotten rid of all of them by understanding how the universe works by doing science
    • Religion is just stories, and the stories are inconsistent with how the universe works
  2. Progress of naturalistic science I
    • Newtonian physics refutes the idea that angels push planets around
    • Darwinian evolution refutes design arguments, including the one that Dr. Craig presented (24:10)
    • Biochemistry hasn’t explained how life originated, but we will have the solution soon
    • Physics shows us that matter can be created and destroyed without need a God
    • Physics shows us that universes can be created and destroyed “no problem”
  3. Religious pluralism II
    • Since we have been able to disprove all the gods we’ve invented, why hang on to the last one
    • It’s unlikely that the God that Dr. Craig presented exists, because we disproved all the others he didn’t present
  4. Hiddenness of God
    • There is a complete lack of evidence for the other 999 gods, so how likely is it that the God Dr. Craig presented exists
  5. Religious pluralism III
    • There are inconsistencies between various religions, so therefore there can be no religion that is right
  6. Progress of naturalistic science II
    • Peasants had a very low level of knowledge about the world and they believed in God
    • But our level of knowledge has increased over time, so we shouldn’t believe in God now
    • Peasants thought that the Earth orbited the Sun, but this is now known to be false
    • The Scriptures said that the Earth orbited the Sun, but now we know that’s false from science
  7. Christianity plagiarizes from other religions I
    • There is nothing new or special about Jesus
    • He’s just as unpleasant as all the other gods
    • Everything particular to Jesus occurs in other religions
  8. Catholics are inconsistent about what they believe
    • I’ll bet most Catholics don’t really believe in transubstantiation
    • I’ll bet most Catholics don’t really believe in the virgin birth
  9. The resurrection is copied from many other religions
    • Dionysus, Osiris, etc.
  10. There is no evidence for the resurrection
    • The stories about Jesus were written “decades or hundreds of years after the fact”
    • The stories are inconsistent with each other
    • Dr. Craig tells me that historical Jesus scholars all accept that the resurrection happened
    • That’s like saying that all alien abductions experts agree that alien abductions happened
    • It’s unreasonable to think that the resurrection happened because no one saw it happen
    • I accept that people reported on appearances, but hallucination theory can explain that
  11. The timeline for the creation and incarnation are all wrong
    • The creation, planet formation, hominids, incarnation, etc. all take place in the wrong times
    • If God knew what he was doing, he would done everything at better times to be more efficient
  12. David Hume’s argument against miracles is sound
    • Extraordinary claims require extraordinary evidence – nothing wrong with this argument
    • Miracles are really just coincidences
    • Catholic apparitions at Lourdes disprove the historical argument that Dr. Craig made for the resurrection
  13. God is petty and jealous
    • God shouldn’t demand that we trust him, esteem him and consider his character when we make decisions
    • The atoning death of Jesus for the sins of the world also makes no sense
  14. Belief is based on geography
    • What you believe is clearly correlated with where you are born
    • There is even an Islamic clone of Dr. Craig who “uses the exact same arguments” that he does to prove Islam
    • Belief in God is decreasing in the Internet-accessible world
  15. Science can develop morals without God
    • Reason is able to guide our actions to be moral
    • Morality evolves over time, so there is no objective morality
    • Catholicism teaches things that are immoral
    • Some things are prohibited by biological revulsion, such as incest
    • But if a brother and sister have sex using condoms “is that morally wrong? I can’t say it is frankly” (37:24)
  16. Dr. Craig is irrational
    • “I came here convinced based on my past interactions and his writing that Dr. Craig was a dishonest Charlatan”
    • “Any argument that validates God is reasonable to him”
    • “And any argument against it is not only unreasonable but wrong and worth distorting”
    • “Because it must be wrong – he’s decided the answer in advance”
  17. Dr. Craig is immoral
    • Dr. Craig thinks it is OK for God to command that Canaanite children are killed
    • “So in fact if they were Canaanite children in that schoolroom that he talked about then it would be OK”
    • It’s not reasonable to justify genocide in that way, but Dr. Craig is willing to go to those lengths
  18. The cause of the origin of the space time universe need not be God
    • Dr. Craig says that if there is an explanation for the origin or space, time, matter and energy it must be God
    • But it could just as easily be turtles or Zeus
  19. Dr. Craig misrepresents the Borde Guth Vilenkin theorem
    • Alexander Vilenkin wrote me an e-mail that says that the theorem doesn’t work in all cases
    • “Dr. Craig is so convinced that these arguments must be true that he won’t listen to the fact that they’re not”
  20. Darwinian evolution explains the fine-tuning
    • “Life was fine tuned – we got rid of it with Darwin”
    • Mutation and natural selection explain the cosmic fine-tuning argument that Dr. Craig presented
  21. Suboptimal design disproves the fine-tuning argument
    • “We get back aches” therefore “This argument that [the universe] is fine-tuned for life is nonsense”
  22. William Lane Craig can be proven to exhibit homosexual behavior using logical arguments
    • Look, you can construct arguments that are clearly wrong
    • Premise 1: “All mammals exhibit homosexual behavior”
    • Premise 2: “William Lane Craig is a mammal”
    • Seems to be saying that logical arguments can prove false things “it’s nonsense”
  23. Dr. Craig distorted a podcast that some group made on pain receptors
    • Dr. Craig’s faith is so strong that it causes him to distort what this group said

Discussion: (44:35)

I will not be summarizing everything that was said, just a few main points.

The segment from 52:18 to 57:12 about the Vilenkin e-mail on the BVG theorem is a must-see. Krauss is standing up and gesticulating while Craig is calmly trying to quote a paper by Vilenkin that shows that Krauss is misrepresenting Vilenkin. Krauss constantly interrupts him. After a while, when Craig exposes him as having misrepresented Vilenkin and gets him to admit that all current eternal models of the universe are probably wrong, he quietens down and can’t even look at Craig in the face.

Cosmological argument:

  • Craig: The e-mail says any universe that is expanding, on average, requires a beginning
  • Craig: There are two models – Aguirre & Gratton and Carroll & Chen – where there is a period of contraction before the expansion
  • Craig: The two models are the ones cited in the e-mail that Dr. Krauss showed
  • Craig: In the very paper by Vilenkin that I cited, he says that both of those models don’t work
  • Krauss: (agitated and interrupting) Vilenkin said that they have to make an assumption about entropy that they have no rationale for
  • (as Craig starts to talk Krauss makes an exaggerated, disrespectful gesture and sits down in a huff)
  • Craig: Yes, an unwarranted assumption means that they don’t have EVIDENCE for their theories being correct
  • Krauss: (agitated and interrupting) “All the evidence suggests that the universe had a beginning but WE DON’T KNOW!!!!!!!” (raising his voice)
  • Craig: I’m not saying that we know that the universe had a beginning with certainty
  • Craig: I am saying that the beginning of the universe is more probably true than false based on the evidence we have
  • Craig: And you  agree with me about that – you think the universe had a beginning
  • Krauss: (agitated and interrupting) (Unintelligible)
  • Moderator: One at a time
  • Craig: In your Vilenkin e-mail slide, at the end of the paragraph where the two models are mentioned that Vilenkin specifically shows…
  • (I am guessing that Craig is going to ask why so much of what Vilenkin wrote has been cut out of the e-mail that Krauss showed)
  • Krauss: (agitated and interrupting) Because it was technical…
  • Moderator: Lawrence! Hang on a sec!
  • Craig: He specifically shows that these models are not past eternal, and that they require a beginning just like the others…
  • Krauss: (agitated and interrupting) We can do the math if you want
  • Craig: Now wait. I couldn’t help notice that there on your slide there was a series of ellipsis points indicating missing text…
  • Krauss: (agitated and interrupting) “Yeah, because it was technical!”
  • Craig: “I wonder what you deleted from the original letter”
  • Krauss: (agitated and interrupting) “I just told you!”
  • Craig: “Now wait. Could it have been something like this:  (reads a quote from Vilenkin) ‘You can evade the theorem by postulating that the universe was contracting prior to some time. This sounds as if there is nothing wrong with having contraction prior to expansion. But the problem is that a contracting universe is highly unstable. Small perturbations would cause it to develop all sorts of messy singularities, so it would never make it to the expanding phase.’
  • Craig: “That’s Vilenkin.”
  • Krauss: “In this paper, that’s absolutely right”
  • Krauss: But it’s ok for theories to assume things that we know are wrong – they are still good theories – it’s unknown
  • (Craig turns away and looks through his papers)
  • Craig: “Isn’t it true that the only viable quantum gravity models on order today involve a beginning – have a finite past?”
  • Krauss: “No”
  • Craig: “Well, can you give us one then”
  • Krauss: (talks about a variety of possible eternal models) “In my experience in science, all of them are probably wrong”
  • Krauss: “You know most theories are wrong, which is why, you know, it’s hard”
  • Craig: “Right”

I noticed that a huge number of atheist web sites are taking the Vilenkin quote that Krauss used out of context, like this one and this one. There are probably a lot more of them like that, which I think is interesting. That’s why we have these debates, I guess. To set the record straight about who accuses people of being dishonest, and who is actually dishonest.

Fine-tuning:

  • Krauss tried to argue that he had explained the fine-tuning with the Higgs particle, but Dr. Craig said that only applied to the cosmological constant, not all the other examples of fine-tuning. Krauss said that it wasn’t impressive that this universe permitted life and that “It would have been much more surprising if we evolved in a universe in which we couldn’t live”. Krauss argued the fine-tuning was only for “Life like us”. But Dr. Craig explained that the fine-tuning is what allows us to have the basics of any kind of life, like slow-burning stars, chemical diversity, etc. – things that are required for basic minimal life functions in any living system. Craig said that he was working with the current physical laws of this universe (F = ma, etc.) and that he was looking at what changed if we changed those even slightly. Krauss tried to say that if he changed things like the mass of particles then the strength of forces would change. (But the forces aren’t laws!) Krauss argued that the cosmological constant would be even better for life if it was zero, and Craig said that the life permitting range did include zero, but that the range of life-permitting values was narrow.

Jesus’ existence:

  • Craig reponded to the mystery religions charge, the charge that the evidence for the minimal facts is too late/too weak, the charge that grief visions explained the evidence better, and Hume’s argument against miracles. Craig brought up the early creed from 1 Cor 15:3-7 and explained to Krauss that it was 5 years after the events, and that Jewish standards of oral transmission were strong enough to ensure that the creed was reliable, and most of the eyewitnesses would still have been alive.

Audience Q and A: (1:21:09)

The first topic is the grounding of morality. Krauss agrees that there is no objective morality and no objective moral oughts. He also said that that standards of behavior are arbitrary, and that they change over time and they are adopted for promoting social order. Dr. Craig pressed the point that science itself would collapse without ethical values. It assumes them, but cannot ground them.

The next topic was free will. Krauss is a determinist. Craig asked him how he could reconcile moral responsibility with determinism.

The next topic was the effectiveness of mathematics. Krauss didn’t have an explanation for it and didn’t think it needed one. Then they got into whether the Genesis has been verified by science and whether it is meant to be taken literally.

The next topic was whether philosophy makes any progress. Craig gave the example of verificationism being rejected as too narrow, and self-refuting. Krauss: “I’m going to come to the defense of philosophy for the first time”. Craig: “That’s amazing!” Krauss said that science provides new knowledge. Craig said there were some things that could be known apart from science.

Is the Big Bang cosmology a theistic or atheistic theory of cosmic origins?

Christianity and the progress of science
Christianity and the progress of science

Dr. Michael Strauss is a practicing particle physics employed as a professor at University of Oklahoma. He does research in particle physics at CERN, a large hadron collider. It’s safe to assume that he knows something about experimental physics.

Here’s what he writes about Christians and the Big Bang at his new blog:

When my children were young, I would often drive to the home of the person babysitting my kids, usually a young teenage girl, pick her up, then drive her back to my house.  In the car I would ask questions about her interests or her school.  In addition, I would sometimes ask a question that intrigued me since I am a scientist and a Christian, “Do you think the Big Bang is a theistic theory or an atheistic theory?”  Now that question is not on most people’s list of babysitter interview questions, but I was interested to know their answer even though it would not affect their monetary tip. Every time I asked this question I always got the same answer, that the Big Bang is an atheistic theory.  This is just one example of the fact that many kids growing up in an evangelical church environment have the perception that the Big Bang is an idea which removes God as the creator.  It seems that many Christians may disdain the Big Bang.

Subsequent conversations with people of all ages have shown me that many individuals (1) don’t really understand what the Big Bang is, (2) don’t know the scientific evidence for the Big Bang, and (3) don’t comprehend the theistic significance of the Big Bang.   So let’s explore these ideas a little bit.

Here is his overview of the scientific evidence for the Big Bang:

There are three primary observations that are best explained by the Big Bang.  First, the universe is expanding so that it must have had a beginning of expansion in the past.  Second, because the universe was once very hot, we can still see the remnants of that heat in the Cosmic Microwave Background (CMB) radiation.  The latest measurements of the CMB spectrum made by the Planck satellite (shown above) agrees almost perfectly with theoretical calculations using the standard Big Bang cosmological model (see the plot at the end of this post).  Third, the theory predicts the amount of primordial light elements that should have been created in the first few minutes of the Big Bang, like hydrogen and helium.  Again the observations and the theoretical calculations align almost exactly.   A few other observations are supported by Big Bang predictions, like the distribution of galaxies and primordial gas.  The agreement between what we measure and what is expected from a Big Bang is so remarkable that just about all scientists accept the Big Bang as the origin of our universe, despite its implication that the universe had a beginning.

Does this scientific evidence support theism, or atheism?

Because we don’t have any observations that tell us exactly what happened “in the beginning” of our universe, we can only speculate.  But let me point out the obvious.  All of the observations we do have, and all the theoretical calculations, and even some projective calculations like the Borde-Guth-Vilenkin theorem (which I should probably blog about at some time) give credence to the conclusion that all of the space, time, matter, and energy of this universe had a beginning.  The Big Bang is a misnomer for it is not some kind of explosion since there was nothing that existed to explode.  It is the origin of the universe.  So if this universe had a beginning, then the cause of the universe can not be a part of the universe.  The cause must be transcendent, like the Christian idea of God.  Is the fact that all the evidence points to our universe having a transcendent cause proof for God?  No, but it is extremely powerful evidence.  If one hundred years ago you had predicted that scientists would obtain unambiguous evidence about the history of the universe for 13.8 billion years, all of its lifetime except the first fraction of a second, and that all of the evidence would point to an actual beginning consistent with a transcendent cause, I don’t think anyone would have taken you seriously.  But that is exactly what has happened.  Theists could not have outlined a better scenario to support theism.  The scientific facts are completely consistent with the statement, “In the beginning God created the heavens and the earth.”

Now I’ve had conversations with atheists about this scientific evidence during my lifetime. And the conversations always go like this: I lay out the experimental evidence and theoretical evidence for a cosmic beginning, and they start to talk about science fiction: Star Wars and Star Trek. But there are also famous atheists who have tried to account for the Big Bang cosmology in their atheistic worldview.

Here’s Oxford University professor of physical chemistry (and atheist) Peter Atkins explaining how he grounds the Big Bang cosmology:

Easy! Nothing actually exists, according to Peter Atkins.

What about a theoretical physicist, like Lawrence Krauss? Well, he just redefines the nothing that causally preceded the origin of the universe so that it is actually something. Pure speculation, and it goes against the experimental scientific evidence we have. Exactly what you’d expect from a man who wrote a book about the physics of “Star Trek”.

You don’t get to start with the laws of physics in the Big Bang cosmology. You don’t get to start with an electron. You don’t get to start with a quantum vacuum, nor even quantum foam. You start with nothing: no matter, no energy, no space, and no time. From that state, the universe begins to exist. Atheists hate the Big Bang cosmology. And they also hate the fine-tuning of the initial conditions of the Big Bang that allows the universe to support complex, embodied intelligent life. (Another miraculous evidence for God that is opposed by the anti-science fundamentalists).

I see resistance against the use of scientific evidence to support the existence of God from many pious pastors like Al Mohler, Russell Moore, etc. Some pastors think that you can just read the Bible out loud to someone and it will convert them to Christianity, as if the words of the Bible, in and of themselves, were some sort of incantation. It’s sort of like the “burning of the bosom” that Mormons are supposed to have when reading the Mormon Bible, which Mormons use in place of evidence, since they don’t have any. Many fideist pastors adopt this Mormon approach to trusting in God. Never mind that Jesus offered his resurrection as evidence of his claims to divinity to skeptics. Apparently, These pious pastors know better than Jesus how to evangelize non-Christians, and they’ve decided that the magic words fideist approach is better than use of scientific and historical evidence. It’s really annoying that the pious pastors have so much more influence in churches than the witness of experimental science, which is just God speaking to us through nature. I’d trust scientific evidence over an uneducated fundamentalist pastor any day of the week.

Luke Barnes discusses the fine-tuning of the fine structure constant

Fine-tuning of the strong nuclear force and the fine structure constant
Fine-tuning of the strong nuclear force and the fine structure constant

Here is an article from The New Atlantis written by cosmologist Luke Barnes about one specific example of cosmic fine-tuning. (H/T Uncommon Descent via J. Warner Wallace tweet)

Excerpt:

Today, our deepest understanding of the laws of nature is summarized in a set of equations. Using these equations, we can make very precise calculations of the most elementary physical phenomena, calculations that are confirmed by experimental evidence. But to make these predictions, we have to plug in some numbers that cannot themselves be calculated but are derived from measurements of some of the most basic features of the physical universe. These numbers specify such crucial quantities as the masses of fundamental particles and the strengths of their mutual interactions. After extensive experiments under all manner of conditions, physicists have found that these numbers appear not to change in different times and places, so they are called the fundamental constants of nature.

These constants represent the edge of our knowledge. Richard Feynman called one of them — the fine-structure constant, which characterizes the amount of electromagnetic force between charged elementary particles like electrons — “one of the greatest damn mysteries of physics: a magic number that comes to us with no understanding by man.”

[…]A universe that has just small tweaks in the fundamental constants might not have any of the chemical bonds that give us molecules, so say farewell to DNA, and also to rocks, water, and planets. Other tweaks could make the formation of stars or even atoms impossible. And with some values for the physical constants, the universe would have flickered out of existence in a fraction of a second. That the constants are all arranged in what is, mathematically speaking, the very improbable combination that makes our grand, complex, life-bearing universe possible is what physicists mean when they talk about the “fine-tuning” of the universe for life.

Atheists, both rank-and-file and expert, almost universally misunderstand the fine-tuning argument. They imagine that if the constants and quantities specified at the origin of the universe were different, then humans would just have green skin, or maybe forehead ridges, or pointy ears. Atheists tend to get their view of science from science fiction in novels or television or movies, and they base their worldview off of fantasies, since this is less thinking and feels better than letting the scientific evidence influence their worldview.

So what does the scientific evidence actually show?

Barnes explains:

The strong nuclear force, for example, is the glue that holds protons and neutrons together in the nuclei of atoms. If, in a hypothetical universe, it is too weak, then nuclei are not stable and the periodic table disappears again. If it is too strong, then the intense heat of the early universe could convert all hydrogen into helium — meaning that there could be no water, and that 99.97 percent of the 24 million carbon compounds we have discovered would be impossible, too. And, as the chart to the right shows, the forces, like the masses, must be in the right balance. If the electromagnetic force, which is responsible for the attraction and repulsion of charged particles, is too strong or too weak compared to the strong nuclear force, anything from stars to chemical compounds would be impossible.

Stars are particularly finicky when it comes to fundamental constants. If the masses of the fundamental particles are not extremely small, then stars burn out very quickly. Stars in our universe also have the remarkable ability to produce both carbon and oxygen, two of the most important elements to biology. But, a change of just a few percent in the up and down quarks’ masses, or in the forces that hold atoms together, is enough to upset this ability — stars would make either carbon or oxygen, but not both.

It’s very important that theists are well-equipped to explain how individual cases of fine-tuning work. We need to know what you lose if you alter these constants and quantities even slightly. You can read about some more examples in this previous post.

British Spitfire and German Messerschmitt Me 109 locked in a dogfight

Here’s a debate with a well-qualified atheist and Dr. Craig.

Video:

Audio:

Description from the Youtube upload:

This debate on “Does God Exist?” took place in front of a capacity audience at the Great Hall, University of Birmingham. It was recorded on Friday 21st October 2011 as part of the UK Reasonable Faith Tour with William Lane Craig.

William Lane Craig is Research Professor of Philosophy at Talbot School of Theology, La Mirada, California and a leading philosopher of religion. Peter Millican is Gilbert Ryle Professor of Philosophy at Hertford College, University of Oxford and a noted scholar in studies of Hume.

The debate was hosted by the University of Birmingham Student Philosophy Society, and the debate was moderated by Professor Carl Chinn.

Dr. Millican proved to be an amazing debater, and that allowed Dr. Craig to show the full range of his talents in a way that he has never done before. This was a great debate – right up there with Craig’s two debates against Austin Dacey and Paul Draper. Dr. Millican is excellent at analytical philosophy, had studied cosmology and physics, and he came prepared to answer Craig’s arguments. There is NO SNARK in my debate summary below, out of respect for Dr. Millican. However, I haven’t proof-read it, so please do point out any errors. There is about 30 minutes of Q&A time at the end.

Dr. Craig’s opening speech:

There are good reasons to believe that God exists.

There are no good reasons to believe that God does not exist.

A1) The origin of the universe

  1. The universe began to exist
  2. If the universe began to exist, then the universe has a transcendent cause.
  3. The universe has a transcendent cause.

The origin of the universe is confirmed by philosophical arguments and scientific evidence.

There cannot be an actual infinite number of past events, because mathematical operations like subtraction and division cannot be applied to actual infinities.

The Borde-Guth-Vilenkin (BGV) proof shows that every universe that expands must have a space-time boundary in the past. That means that no expanding universe, no matter what the model, cannot be eternal into the past.

Even speculative alternative cosmologies do not escape the need for a beginning.

The cause of the universe must be transcendent and supernatural. It must be uncaused, because there cannot be an infinite regress of causes. It must be eternal, because it created time. It must be non-physical, because it created space. There are only two possibilities for such a cause. It could be an abstract object or an agent. Abstract objects cannot cause effects. Therefore, the cause is an agent.

A2) The fine-tuning of the universe

  1. The fine-tuning of the universe is either due to law, chance or design.
  2. It is not due to law or chance.
  3. Therefore, it is due to design.

The progress of science has revealed that the Big Bang was fine-tuned to allow for the existence of intelligent life.

Type 1: Constants like the gravitational constant are finely-tuned, and are not dependent on the laws of physics.

Type 2: Quantities like the amount of entropy in the universe, are not dependent on the laws of physics.

The range of life-permitting values is incredibly small compared to the possible values of the constants and quantities. (Like having a lottery with a million black balls and one white ball, and you pick the white ball. Even though each individual ball has the same tiny chance of being picked, but the odds are overwhelming that the whichever ball you pick will be black, and not white).

Not only are the numbers not due to laws, but they are not due to chance either. It’s not just that the settings are unlikely, it’s that they are unlikely and they conform to an independent pattern – namely, the ability to support complex life.

A3) The moral argument

  1. If God does not exist, then objective moral values do not exist.
  2. Objective morality does exist.
  3. Therefore, God exists.

Objective moral values are values that exist independently of whether any humans believe them or not.

Michael Ruse, an atheist philosopher agrees that if God does not exist, then there is only a “herd morality” that is determined by biological evolution and social evolution. There no objective moral standard, just different customs and conventions that vary by time and place. Anyone who acts against the herd morality is merely being unfashionable and unconventional. On the atheistic view, there is nothing objective and binding about this evolved “herd morality”. However, people do experience objective moral values, and these cannot be grounded on atheism.

Furthermore, God must exist in order to argue that there is evil in the world. In order to be able to make a distinction between good and evil that is objective, there has to be a God to determine a standard of good and evil that is binding regardless of the varying customs and conventions of different people groups. Even when a person argues against God’s existence by pointing to the “evil” in the world, they must assume objective moral values, and a God who grounds those objective moral values.

A4) The resurrection of Jesus.

  1. There are certain minimal facts that are admitted by the majority of historians, across the ideological spectrum: the empty tomb, the appearances and the early belief in the resurrection.
  2. Naturalistic attempts to explain these minimal facts fail.
  3. The best explanation of these facts is that Jesus rose from the dead.

A5) Religious experience

People can know that God exists through experience. In the absence of defeaters for these experiences, these experiences constitute evidence for God’s existence.

Dr. Millican’s opening speech:

Dr. Craig has the burden of proof because he claims that God exists.

The Christian God hypothesis:

  1. An omnipotent, omniscient, omnibenevolent God created the universe.
  2. This God cares about humans.
  3. This God has acted in history though the life of Jesus of Nazareth.

This is a factual claim, and we are discussing the evidence for whether these claims are true or false. We are not interested in religious practice, or the consolation of religious belief, nor any other religions.

A1) Religious pluralism and epistemology

Human beings are purpose-finding creatures – we are prone to prefer explanations that involve purpose.

Human beings are pattern-finding animals – we tend to find designs in states of affairs.

Human beings have an interest in maintaining religious hierarchies because of the power it gives them.

Religious beliefs are not determined by rational considerations, but are determined by geographic location.

The same non-scientific method of generating religious beliefs (purpose-finding, pattern-finding, geographic location, parental teaching, charismatic speakers, praise songs and worship, religious education, ancient holy books) is being used in several religions, and it leads to different, contradictory truth claims. So at least some of those conflicting claims are false. And if the method is generating some false claims, then it’s not a good method, and it undermines all the religions that use those methods.

A2) Absence of evidence is evidence of absence

There is no scientific evidence for God.

A3) Mental processes depend on physical systems

There is no scientific evidence for a disembodied intelligence.

Our universal human experience is that intelligence and mental operations require a physical brain.

The quality of our thinking depends on physical conditions, like being tired or on drugs.

But Christian theists believe that mental processes can exist independently of an underlying physical reality, unimpaired by the death of the physical body and the brain.

R.A1) The origin of the universe

1. There is no evidence that whatever begins to exist requires a cause. All the evidence we have of things beginning to exist are when something is created from rearrangements of other things that already existed.

The closest analog we have to something coming into being from nothing is quantum particles coming into being from nothing, and that causation is random.

There is no evidence that thoughts can bring about physical effects, and Bill is arguing for a mental cause to the origin of the universe.

Even if things that begin to exist IN the universe have causes, it doesn’t hold for the universe as a whole. Bill is committing the fallacy of composition.

Time begins with the universe, but our experience of causation is that it is a temporal process. So if there is no time “prior to” the universe’s beginning, then how can there be a cause to the universe?

It’s possible that there could be something outside our universe that is eternal.

It’s also possible that the Big Bang could be wrong, and this universe could oscillate eternally and not require a beginning.

2. There are cosmological theories that avoid the beginning of the universe by positing a prior period of contraction prior to the Big Bang.

The beginning of this universe depends on general relativity, and that theory breaks down at the level of quantum mechanics.

3. There is no evidence that minds can exist without an underlying physical system. So even if there is a cause of the universe, then it is neither an abstract object nor a mind. It would have to be something else, and not something we are familiar with – we are just not in a position to speculate of what it could be.

R.A3) The moral argument

Atheists do believe in a standard of morality that is not based on what groups of humans believe.

Utilitarians think there is a standard of moral values that is objective, because the measure of human happiness (for the greatest number) is objective, even if people are mistaken about what promotes that happiness.

Kantians have a rational process for determining which moral imperatives should be universalized.

Humeans have a system that is rooted in natural human sentiment.

Dr. Craig’s first rebuttal:

I do not have the only burden of proof. The topic is “Does God Exist?”. If Dr. Millican answers “no” then he has a burden of proof, otherwise we are left with agnosticism.

R.A1) Religious pluralism and epistemology

First, there is no single common method of adopting a religion.

Second, MY method this evening is logic and evidence and personal experience – which is the same as his method. So his comments about how people in different religions adopt their religion through parents, church, singing, etc. have no bearing on the arguments I will be making.

R.A2) Absence of evidence is evidence of absence

Absence of evidence is only evidence of absence if we can reasonably expect that there should be some evidence that is not present. He would have to show that there should be more evidence for God’s existence that the 5 arguments that I already presented – something that we should expect to see that we don’t see.

R.A3) Mental processes depend on physical systems

No response by Dr. Craig. (but see below)

A1) The origin of the universe

1. He says that there are speculative cosmologies like the multiverse that escape the need for a beginning, but that’s false, the BGV proof applies to them, and they do need a beginning.

He says that you can escape BGV by positing a contraction prior to the expansion. However Vilenkin says that any contraction phase is unstable and would introduce additional singularities that would hamper any later expansion phase.

He  says that we need a theory of quantum gravity in order to describe the early universe. But Vilenkin says that the BGV proof is independent of gravity as defined by general relativity.

He did not respond to the philosophical arguments for a beginning of the universe.

2. He says that we don’t have experience of things coming into being except from material causes. However, it would be even more difficult to explain the universe coming into being on atheism since you can’t appeal to a material cause nor to an efficient cause. Even Hume recognizes that things can’t pop into being without causes.

He talks about how in quantum physics virtual particles appear out of nothing. But that’s false, because the quantum vacuum in which virtual particles appear is not nothing, it is a sea of subatomic particles and energy. Quantum physics is not an exception to the idea that things that come into being require a cause.

He mentions the fallacy of composition. But I am not saying that everything in the universe has a cause, therefore the universe as a whole has a cause. I am saying that non-being has no capacity to bring something into being. Non-Being doesn’t even have the potential to bring something into being.

3. He says that there are no unembodied minds, so the cause of the universe can’t be an unembodied mind. But the argument concludes that there is a non-material cause, and it can’t be an abstract object, so it would have to be a mind.

In addition, we ourselves are unembodied minds.  This is because physical objects cannot have the properties that minds have, like the property of having feelings.

Material conceptions of mind don’t explain identity over time.

Material conceptions of mind don’t explain free will.

Material conceptions of mind don’t explain intentional states (thinking about something).

Material conceptions of mind don’t explain mental causation.

The best explanation for our own first person experience of the mental realm is a substance dualism. We are non-material minds, and we can cause effects in the physical world. And God does the same thing. He is a mind, and he causes physical effects.

A2) He gave no response.

A3) He says that there are atheistic theories of morality that don’t depend on the opinions of groups. But these theories all depend on the idea that human beings have instrinsic value – that they are the sorts of things to which moral considerations apply. Naturalism cannot ground this moral value – human beings are no more valuable any other animal.

Also, there are no objective moral obligations in naturalist systems of morality, because there is no one in authority to command them. Moral prescriptions require moral prescribers.

A4) He gave no response.

A5) He gave no response.

Dr. Millican’s first rebuttal:

R.A2) The fine-tuning argument

We have to be careful not to judge what counts as finely-tuned through our intuitions.

We have to be careful about reasoning for a sample size of this one observable universe.

We don’t really know about the full range of possibilities for these constants and quantities.

There might be other universes that we can’t observe that aren’t fine-tuned, and we just happen to be in the one that is fine-tuned.

The fine-tuning might be solved by future discoveries, like the inflationary cosmology removed some of the fine-tuning.

There might be a multiverse that we don’t have evidence for right now.

We need to be careful about using science to prove God because science might change in the future.

The universe is very big and mysterious.

This argument doesn’t prove that God is good. He could be evil = anti-God.

God created the universe inefficiently if his goal was to produce life.

God created the universe too big.

God created the universe too old.

God created too many galaxies and stars that are not hospitable to life.

If the universe were fine-tuned for life, then there should be more aliens.

If the universe were fine-tuned for life, then there are probably lots of alien civilizations. But then Jesus would have to appear to all of the aliens too.

R.A1) The origin of the universe

2. It’s not a big deal that you can get multiple solutions to equations involving subtraction of actual infinities. For example, the equation 0 x y = 0 has many solutions for y, but that doesn’t mean that multiplication doesn’t work in the real world.

A2) Absence of evidence is evidence of absence

I would expect that there would be more evidence than there is.

R.A1) The origin of the universe

2. The BVG proof might be overturned by future scientific discoveries. We have no reason to be confident in current physics.

I agree that the quantum vacuum is something and not nothing, but it’s similar to nothing.

We don’t have any reason to believe that things that come into being require causes – except for our universal experience that this is always the case.

3. As to the cause of the universe coming into being, you said that it could only be an abstract object or a mind, and it can’t be an abstract object because they don’t cause effects, so it must be a mind. But there are all sorts of things we’ve never thought of that it could be other than a mind.

I agree that mental properties are not physical properties and that epiphenomenalism is incorrect. Physical objects can have “algorithmic properties” as well as physical properties, it doesn’t mean that computers have minds.

Dr. Craig’s second rebuttal:

R.A2) Absence of evidence is evidence of absence

He expressed his personal opinion that there should be more evidence, but that’s not an argument.

God knows how people will respond to getting more evidence or less evidence and he has to be careful not to take away their free will to disbelieve by piling them up with coercive evidence. God’s goal is not just to convince people that he exists. God’s goal is to have people respond to him and pursue him.

A1) The origin of the universe

2. He said that multiple answers to equations are no problem. But the problem is that you can’t translate multiple answers into a real world context.

The problem is that you are subtracting an identical number from an identical number and getting contradictory results, and that cannot be translated into the real world, where subtraction always gives a definite single result.

He talks about how you can get multiple answers with multiplication by 0. But 0 is not a real quantity, it is just the absence of something, and that cannot translate into the real world, because it has no being.

He says that I am only using evidence from current physics. But that is the point – the evidence of current physics and cosmology supports the beginning of the universe.

3. He said that an umembodied mind can’t be the cause, but we are minds and we cause effects on our physical bodies.

In addition, the design argument supports the idea that the cause of the universe is intelligent.

A2) The fine-tuning of the universe

He says we should be cautious. Of course.

He says the probabilities can’t be assessed. But you can just take the current value and perturb it and see that the resulting universe loses its ability to support life, and you can test an entire range around the current value to see that that vast majority of values in the range don’t permit life.

He says that the current physics is not well-established, but there are so many examples of fine-tuning across so many different areas of science that it is not likely that all of them will be overturned, and the number of finely-tuned constants and quantities has been growing, not shrinking.

He says it doesn’t prove that God is good, and he’s right – that’s what the moral argument is for.

He says that God isn’t efficient enough, but efficiency is only important for those who have limited time and/or limited resources. But God has unlimited time and resources.

He says that the universe is too old, but the large age of the universe is a requirement to support intelligent life – (i.e. – you need third generation stars to provide a stable source of energy to planets, and those stars require that two generations of stars are born and die).

He said what about aliens, and theists are open to that, and God can certainly provide for the salvation of those beings, if they have fallen into sin.

Dr. Millican’s second rebuttal:

R.A1) The origin of the universe

3. Just because epiphenominalism is false, it doesn’t mean that substance dualism is true.

The majority of philosophers of mind do not accept substance dualism.

R.A3) The moral argument

The majority of philosophers are moral realists, but a minority of philosophers are theists. So that means that there must be some way of justifying morality on atheism, which I will not describe right now.

Atheists can express their opinion that humans have intrinsic moral value.

He grants that atheists can perceive moral values. But if atheists can perceive moral values, then why is God needed to enable that?

Atheists can express their opinion that humans are special. We can be rational, and that makes us special.

Atheists can express their opinion that it is good to care about other humans because they are of the same species.

R.A4) The resurrection of Jesus

We don’t have any reasons to believe i the supernatural.

The gospels are written late for the purposes of evangelism.

The gospels are not independent, e.g. Matthew and Luke depend on Q.

John is the latest gospel, and the Christology of John is the highest of all.

The four gospels agree because the early church rejected other (unnamed) gospels that didn’t agree.

Matthew 27 – the earthquake and the raised saints – is not recorded in any other contemporary non-Christian source.

Dr. Craig’s final rebuttal:

A3) The moral argument

He says that human beings are rational, and that gives them value. But atheists like Sam Harris prefer the flourishing of sentient life. He includes non-rational animals as having moral value. So without God, we see that the choice of who or what has moral value is arbitrary. And where would objective moral duties come from if there is no moral lawgiver?

The fact that most atheists accept objective moral values doesn’t mean that they can rationally ground those values on their atheistic worldview. You can’t provide a basis for moral values on atheism by counting the number of atheists who accept objective morality. It’s not surprising that atheists can perceive objective moral values IF they are living in auniverse created by God who grounds these objective moral values and duties that atheists perceive.

A4) The resurrection of Jesus

He cites Geza Vermes and Bart Ehrman as authorities on the historical Jesus, but both of them accept all three of the facts that I presented as minimal facts. Ehrman doesn’t accept the resurrection of Jesus because he presupposes naturalism. He rejects the resurrection on philosophical grounds, not historical grounds.

Dr. Millican’s final rebuttal:

R.A5) Religious experience

Religious experience is an unreliable way to test the claims of a religion, because lots of religions have them and they make contradictory truth claims. In the future, we may discover naturalistic ways of explaining religious experience.

R.A4) The resurrection of Jesus

Even if you can make a case for the resurrection based on these3  minimal facts, there are other stories in the New Testament like Matthew 27 that are quite weird and they undermine the 3 minimal facts that even Geza Vermes and Bart Ehrman accept.

R.A1) The origin of the universe

Bill hasn’t shown that there is any reason for thinking that things don’t come into being, uncaused, out of nothing.

A4) The problem of evil

Theists can’t explain what God’s specific morally sufficient reasons are for permitting the apparently gratuitous evil that we see.

Robin Collins and atheist Peter Millican discuss the fine-tuning of the universe for life

British Spitfire and German Messerschmitt Me 109 locked in a dogfight
British Spitfire and German Messerschmitt Me 109 locked in a dogfight

You might remember Peter Millican from the debate he had with William Lane Craig. I ranked that debate as one of the 3 best I have ever seen, along with the first Craig  vs Dacey debate and the second Craig vs Sinnott-Armstrong debate.

Details:

Science has revealed that the fundamental constants and forces of the cosmos appear to be exquisitely fine-tuned to allow a universe in which life can develop. Is God the best explanation of the incredibly improbable odds of the universe we live in being a life-permitting one?

Robin Collins is a Christian philosopher and a leading advocate of the argument for God from cosmic design. Peter Millican is an atheist philosopher at Oxford University. They debate the issues.

From ‘Unbelievable?’ on ‘Premier Christian Radio’, Saturday 19th March 2016.

The debate:

As usual when the atheist is an expert, there is no snark or paraphrasing in the summary.

Summary

Brierley: What is the fine-tuning argument?

Collins: the fine-tuning is structure of the universe is extremely precisely set to allow the existing of conscious, embodied agents who are capable of moral behavior. There are 3 kinds of fine-tuning: 1) the laws of nature (mathematical formulas), 2) the constants of physics (numbers that are plugged into the equations), 3) the initial conditions of the universe. The fine-tuning exists not just because there are lots of possibilities, but there is something special about the actual state of affairs that we see. Every set of laws, parameters and initial conditions is equally improbable, but the vast majority of permutations do not permit life. The possible explanations: theism or the multiverse.

Brierley: How improbable are the numbers?

Collins: Once case is the cosmological constant (dark energy density), with is 1 part in (10 raised to 120th power). If larger, the universe expands too rapidly for galaxies and stars to form after the Big Bang. If smaller, the universe collapses in on itself before life could form. Another case is the initial distribution of mass energy to give us the low entropy we have that is necessary for life. The fine-tuning there is 1 part in (10 raised to the 10th power raised to the 123rd power).

Brierley: What do you think of the argument?

Millican: The argument is worth taking very seriously. I am a fan of the argument. The other arguments for God’s existence such as the ontological and cosmological arguments are very weak. But the fine-tuning argument has the right structure to deliver the conclusion that theists want. And it is different from the traditional design argument tended to focus on biological nature, which is not a strong argument. But the fine-tuning argument is strong because it precedes any sort of biological evolution. Although the design is present at the beginning of the universe, it is not visible until much later. The argument points to at least deism, and possibly theism. The argument is not based on ignorance, it is rooted in “the latest results from the frontiers of science” (his phrase).

Brierley: Is this the best argument from natural theology?

Collins: The cosmological argument makes theism viable intuitively, but there are some things that are puzzling, like the concept of the necessary being. But the fine-tuning argument is decisive.

Brierley: What’s are some objections to the fine-tuning argument?

Millican: The argument is based on recent physics, so we should be cautious because we maybe we will discover a natural explanation.

Brierley: Respond to that.

Collins: The cosmological constant has been around since 1980. But the direction that physics is moving in is that there are more constants and quantities being discovered that need to be fine-tuned, not less. Even if you had a grand unified theory, that would have to be have the fine-tuning pushed into it.

(BREAK)

Millican: Since we have no experience of other laws and values from other universes, we don’t know whether these values can be other than they are. Psychologically, humans are prone to seeing purpose and patterns where there is none, so maybe that’s happening here.

Brierley: Respond to that.

Collins: It is possible to determine probabilities on a single universe case, for example using multiple ways of calculating Avogadro’s number all converging on the same number makes it more probable.

Millican: Yes, I willing to accept that these constants can take on other values, (“principle of indifference”). But maybe this principle be applied if the improbability were pushed up into the theory?

Collins: Even if you had a grand theory, selecting the grand theory from others would retain the improbability.

Brierley: What about the multiverse?

Millican: What if there are many, many different universes, and we happen to be in the one that is finely-tuned, then we should not be surprised to observe fine-tuning. Maybe a multiverse theory will be discovered in the future that would allow us to have these many universes with randomized constants and quantities. “I do think that it is a little bit of a promissary note”. I don’t think physics is pointing to this right now.

Brierley: Respond to that.

Collins: I agree it’s a promissary note. This is the strongest objection to the fine-tuning argument. But there are objections to the multiverse: 1) the fine-tuning is kicked back up to the multiverse generator has to be set just right to produce universes with different constants, 2) the multiverse is more likely to produce a small universe with Boltzmann brains that pop into existence and then out again, rather than a universe that contains conscious, embodied intelligent agents. I am working on a third response now that would show that the same constants that allow complex, embodied life ALSO allow the universe to be discoverable. This would negate the observer-selection effect required by the multiverse objection.

Brierley: Respond to that.

Millican: I don’t see why the multiverse generator has to be fine-tuned, since we don’t know what the multiverse generator is. I’m not impressed by the Boltzmann brains, but won’t discuss. We should be cautious about inferring design because maybe this is a case where we are seeing purpose and design where there is none.

Brierley: Can you negate the discoverability of the universe by saying that it might be psychological?

Collins: These things are not psychological. The selected value for the cosmic microwave background radiation is fine-tuned for life and for discoverability. It’s not merely a discoverability selection effect, it’s optimal for discoverability. If baryon-photon value were much smaller, we would have known that it was not optimal. So that judgment cannot be explained by

Millican: That’s a very interesting new twist.

Brierley: Give us your best objection.

Millican: I have two. 1) Even if you admit to the fine-tuning, this doesn’t show a being who is omnipotent and omnisicient. What the fine-tuning shows is that the designer is doing the best it can given the constraints from nature. If I were God, I would not have made the universe so big, and I wouldn’t have made it last 14 billion years, just to make one small area that supports life. An all-powerful God would have made the universe much smaller, and much younger. 2) The fine-tuning allows life to exist in other solar systems in other galaxies. What does this alien life elsewhere mean for traditional Christian theology? The existence of other alien civilizations argues against the truth of any one religion.

Brierley: Respond to those.

Collins: First objection: with a finite Creator, you run into the problem of having to push the design of that creature up one level, so you don’t really solve the fine-tuning problem. An unlimited being (non-material, not composed of parts) does not require fine-tuning. The fine-tuning is more compatible with theism than atheism. Second objection: I actually do think that it is likely that are other universes, and life in other galaxies and stars, and the doctrine of the Incarnation is easily adaptable to that, because God can take on multiple natures to appear to different alien civilizations.
