For those who cannot watch the video, you can grab the MP3 file of the lecture, or read this essay by Dr. Craig which covers exactly the same ground as the video.
Which debate would I consider to be the best to show an intelligent skeptic?
This one, between William Lane Craig and Peter Millican.
The debate was held at the University of Birmingham, England in 2011. I would put this debate in the top 3 Craig debates ever, along with his debates against Austin Dacey and Walter Sinnott-Armstrong.
My summary of the Craig-Millican is below. This debate is really meant for advanced students, but if you read my post “What you need to know about the BVG Theorem” before watching the debate, it should help you to follow along.
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
The universe began to exist
If the universe began to exist, then the universe has a transcendent cause.
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
The fine-tuning of the universe is either due to law, chance or design.
It is not due to law or chance.
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
If God does not exist, then objective moral values do not exist.
Objective morality does exist.
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.
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.
Naturalistic attempts to explain these minimal facts fail.
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:
An omnipotent, omniscient, omnibenevolent God created the universe.
This God cares about humans.
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.
William Lane Craig made 5 arguments for the existence of God:
the contingency argument
theargument from the origin of the universe (kalam)
the argument from cosmic fine-tuning
the moral argument
the argument from the miracle of the resurrection
These arguments went unrefuted during the debate.
Lawrence Krauss’s case
Lawrence Krauss made the following arguments in his first speech:
Dr. Craig is a professional debater
Dr. Craig is not a scientist
Dr. Craig is a philosopher
Disproving God’s is a waste of my valuable time
Dr. Craig has the burden of proof to show evidence
My job is not to present any evidence
I think that “extraordinary claims require extraordinary evidence” is a nice slogan, but I have no evidence for it
I don’t like that God doesn’t appear on Youtube, therefore he doesn’t exist
I don’t like that God didn’t appear to humans until recently, therefore he doesn’t exist
I don’t like that the stars didn’t come together to spell “I am here”, therefore God doesn’t exist
Dr. Craig has to supply extraordinary evidence, because my favorite slogan says he has to
Dr. Craig talks about logic, but the universe is not logical
Dr. Craig doesn’t have any arguments, just things he doesn’t like
Dr. Craig doesn’t like infinity, and that’s why he believes in the Big Bang cosmology
Dr. Craig doesn’t like chance, and that’s why he believes in cosmic fine-tuning
Dr. Craig doesn’t like rape, and that’s why he believes in the ontological foundations of morality
If people believe in logic, then they can’t do science
The things that science discovers contradict the laws of logic
For example, Dr. Craig doesn’t like infinity, so he believes in the experimental measurements of the cosmic microwave background radiation
For example, Dr. Craig doesn’t like chance, so he believes in the fine-tuning of the gravitational constant for the formation of stable stars
Quantum mechanics shows that the universe is stranger than you think, therefore all of Craig’s arguments are false
My t-shirt says 2 + 2 = 5, therefore all of Craig’s arguments are false
Atheism may look ridiculous, but it’s true, and if you don’t like it, too bad – because the universe is very strange
Accidents happen all the time, so that explains the cosmic fine-tuning
We all have to convince ourselves of 10 impossible things before breakfast, and atheism is impossible, so you need to convince yourself of it
I don’t know about the Big Bang, so Dr. Craig cannot use the Big Bang to to prove the universe began to exist
I don’t know about the cosmic fine-tuning, so Dr. Craig cannot use the fine-tuning of cosmological constants to prove the fine-tuning
I don’t know anything about science, so Dr. Craig cannot use science in his arguments
Dr. Craig says that the universe is contingent because it began to exist 13.7 billion years ago based on the state-of-the-art scientific evidence for the Big Bang creation out of nothing from 1) red-shift of light from distant galaxies, 2) cosmic microwave background radiation, 3) helium-hydrogen abundances, 4) experimental confirmation of general relativity, 5) the second law of thermodynamics, 6) radioactive element abundances, etc., but how does he know that? I don’t know that
It’s fine not to know the answer to scientific questions like whether the universe began to exist, it’s more exciting
Thinking that the universe began to exist based on 6 pieces of scientific evidence is the “God-of-the-Gaps” fallacy, it’s intellectual laziness
But all kidding aside, the universe actually did begin to exist 13.72 billion years ago, exactly like Craig says in his argument
I could argue that God created the universe 4.5 seconds ago with all of us sitting believing that we heard Dr. Craig, and how could you prove me wrong? It’s not falsifiable
Universes can spontaneously appear out of nothing, and in fact they have to appear out of nothing
Nothing is unstable, and space and time can come into existence out of nothing, so that’s not a problem
Our universe could have appeared out of a multiverse, an unobservable, untestable multiverse that I have no way of observing or testing
The universe is not fine-tuned for life, and no scientist says so, especially not Martin Rees, the atheist Astronomer Royal, and every other scientist
What if God decided that rape was OK, would it be OK? God can change his moral nature arbitrarily, can’t he?
Here are the arguments in Krauss’ second speech:
We don’t understand the beginning of the universe
We don’t understand whether the universe had a cause
Steven Weinberg says that science makes it possible to be an atheist, so therefore the universe didn’t begin and didn’t have a cause
It’s just intellectual laziness to say that the universe came into being 13.7 billion years ago, and that things that come into being of nothing have a cause
Dr. Craig is an expert on nothing, ha ha ha!
There are multiple versions of nothing, there’s nothing, and then there is something, which is also nothing if I want it to be
There was no space, there was no time, and then the space create the empty space
I’m going to give Dr. Craig a break
At least in the nothing there were laws like F=ma, and those laws created the empty space, because descriptions of matter that does not even exist yet can create space out of nothing
Alan Guth and Alexander Vilenkin are good friends of mine and I talk to them all the time, unlike Dr. Craig
Alan Guth and Alexander Vilenkin don’t mention God in their scientific papers, therefore the universe didn’t begin and didn’t have a cause
Maybe there is a multiverse that cannot be observed or tested? And my unscientific speculations are a refutation of Craig’s scientific evidence for the fine-tuning
Dr. Craig just doesn’t like my speculations about the unobservable, untestable multiverse, and that’s why he believes in the Big Bang cosmology
And if you let me speculate about an unobservable, untestable multiverse, then maybe the inanimate invisible universes reproduce and compete for food and mutate like animals and then there is natural selection so that the finely-tuned universes survive and now we’re in one!
My cool animation of blue goo mutating proves that the multiverse is real! Empty space is not empty!
Darwinism, which is a theory about the origin of species, explains the cosmic fine-tuning that occurred at the moment of creation
The unobservable, untestable multiverse universes all have different laws, I believe
We don’t know what the right answer is, but we are willing to look at any possibility, as long as the possibilities we look at are not supernatural possibilities
The discovery of the origin of the universe could be an accident, I don’t know if the universe began to exist or not, maybe all the six scientific evidences are wrong because if I don’t like the evidence we have, so I’ll just wait for new evidence to overturn the evidence we have which I don’t like
Maybe there are other forms of life that are unobservable and untestable that are compatible with a universe that has no stable stars, no planets, no elements heavier than hydrogen, no hydrogen, no carbon, etc.
Here are the arguments in Krauss’ third speech:
Dr. Craig is stupid
Why should we even care about Dr. Craig’s arguments and evidence, we can just count the number of scientists who are atheists and decide whether God exists that way – I decided everything based on what my teachers told me to believe
What quantum mechanics shows is that virtual particles come into being in a quantum vacuum, and then go out of existence almost immediately – and that is exactly like how a 13.7 billion year old universe came into being in a quantum vacuum, and we’re going to disappear very soon
Space and the laws of physics can be created, possibly, if you accept my speculations about an unobservable, untestable multiverse
I don’t like the God of the Old Testament, therefore he doesn’t exist
Groups of people can decide what they think is good and evil, like the Nazis and slave-owners did, and then that becomes good for them in that time and place, and that’s what I mean by morality
Not knowing things is really exciting! Dr. Craig is not really exciting because he knows things – phooey!
Here are the arguments in Krauss’ fourth speech:
If you will just grant me an observable, untestable multiverse, then there must be some universe where intelligent life exists
Infinite numbers of things exist everywhere in nature, you can see lots of infinite collections of things, like jelly beans and bumblebees and invisible pink unicorns
I don’t like the fine-tuning, but if my speculations about the multiverse are proven true, then I won’t have to learn to live with the fine-tuning
Inflation, the rapid expansion of the universe which occurs at some time after the the origin of the universe (t = 0), explains the absolute origin of time, space, matter and energy out of nothing that occurred at t = 0
Physical processes that develop subsequent to the creation of the universe at t > 0 can explain the fine-tuning of quantities that are set at t = 0
Morality is just a bunch of arbitrary conventions decided by groups of people in different times and places by an accidental process of biological and social evolution, but that practice over there by those people is objectively wrong!
1 Cor 15:3-7, which most scholars, even atheists like James Crossley, admit is dated to within 3 years of the death of Jesus, is actually dated to 50 years after the death of Jesus
The historical case for the resurrection made by people like N.T. Wright in their multi-volume academic works is on par with the story of Mohammed ascending to Heaven on a horse
WINTERY KNIGHT
