Video: William Lane Craig and Peter Millican debate “Does God Exist?”

From Justin Brierley and the Reasonable Faith UK Tour:

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

  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.

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. The debate audio has 32 minutes of Q&A.

And if you like my summary, check out another summary by J.W. Wartick.

Dr. Craig’s opening speech:

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.

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.

Does the progress of science lead to theism or atheism?

You can read more about his recent research on how to use coconuts to make car parts in this article from Science Daily.

Below, I analyze a lecture I chose from the hundreds of public lectures he has given all over the world on the integration of Christian faith with other public, testable areas of knowledge. In this lecture, entitled “Is There Scientific Evidence for an Intelligent Designer?”, Dr. Bradley explains how the progress of science has made the idea of a Creator and Designer of the universe more acceptable than ever before.

The MP3 file is here.

Evidence #1: The design of the universe

1. The correspondence of natural phenomena to mathematical law

  • All observations of physical phenomena in the universe, such as throwing a ball up in the air, are described by a few simple, elegant mathematical equations.

2. The fine-tuning of physical constants and rations between constants in order to provide a life-permitting universe

  • Life has certain minimal requirements; long-term stable source of energy, a large number of different chemical elements, an element that can serve as a hub for joining together other elements into compounds, etc.
  • In order to meet these minimal requirements, the physical constants, (such as the gravitational constant), and the ratios between physical constants, need to be withing a narrow range of values in order to support the minimal requirements for life of any kind.
  • Slight changes to any of the physical constants, or to the rations between the constants, will result in a universe inhospitable to life.
  • The range of possible ranges over 70 orders of magnitude.
  • Although each individual selection of constants and ratios is as unlikely as any other selection, the vast majority of these possibilities do not support the minimal requirements of life of any kind. (In the same way as any hand of 5 cards that is dealt is as likely as any other, but you are overwhelmingly likely NOT to get a royal flush. In our case, a royal flush is a life-permitting universe).

Examples of finely-tuned constants and ratios: (there are more examples in the lecture)

a) The strong force: (the force that binds nucleons (= protons and neutrons) together in nucleus, by means of meson exchange)

  • if the strong force constant were 2% stronger, there would be no stable hydrogen, no long-lived stars, no hydrogen containing compounds. This is because the single proton in hydrogen would want to stick to something else so badly that there would be no hydrogen left!
  • if the strong force constant were 5% weaker, there would be no stable stars, few (if any) elements besides hydrogen. This is because you would be able to build up the nuclei of the heavier elements, which contain more than 1 proton.
  • So, whether you adjust the strong force up or down, you lose stars than can serve as long-term sources of stable energy, or you lose chemical diversity, which is necessary to make beings that can perform the minimal requirements of living beings. (see below)

b) The conversion of beryllium to carbon, and carbon to oxygen

  • Life requires carbon in order to serve as the hub for complex molecules, but it also requires oxygen in order to create water.
  • Carbon is like the hub wheel in a tinker toy set: you can bind other elements together to more complicated molecules (e.g. – “carbon-based life), but the bonds are not so tight that they can’t be broken down again later to make something else.
  • The carbon resonance level is determined by two constants: the strong force and electromagnetic force.
  • If you mess with these forces even slightly, you either lose the carbon or the oxygen.

3. Fine-tuning to allow a habitable planet

  • A number of factors must be fine-tuned in order to have a planet that supports life
  • Initial estimates predicted abundant life in the universe, but revised estimates now predict that life is almost certainly unique in the galaxy, and probably unique in the universe.
  • Even though there are lots of stars in the universe, the odds are against any of them supporting complex life.
  • Here are just a few of the minimal requirements for habitability: must be a single star solar system, in order to support stable planetary orbits, the planet must be the right distance from the sun in order to have liquid water at the surface, the planet must sufficient mass in order to retain an atmosphere, etc.

The best current atheist response to this is to speculate that there may be an infinite number of unobservable and untestable universes.

Evidence #2: The origin of the universe

1. The progress of science has shown that the entire physical universe came into being out of nothing (= “the big bang”). It also shows that the cause of this creation event is non-physical and non-temporal. The cause is supernatural.

  • Atheism prefers an eternal universe, to get around the problem of a Creator having to create the universe.
  • Discovery #1: Observations of galaxies moving away from one another confirms that the universe expanded from a single point.
  • Discovery #2: Measurements of the cosmic background radiation confirms that the universe exploding into being.
  • Discovery #3: Predictions of elemental abundances prove that the universe is not eternal.
  • Discovery #4:The atheism-friendly steady-state model and oscillating model were both falsified by the evidence.
  • And there were other discoveries as well, mentioned in the lecture.

The best atheistic response to this is to speculate that there is an unobservable and untestable hyper-universe outside our own.

Evidence #3: The origin of life

1. The progress of science has shown that the simplest living organism contains huge amounts of biological information, similar to the Java code I write all day at work. This is a problem for atheists, because the sequence of instructions in a living system has to come together all at once, it cannot have evolved by mutation and selection – because there was no replication in place prior to the formation of that first living system!

  • Living systems must support certain minimum life functions: processing energy, storing information, and replicating.
  • There needs to be a certain amount of complexity in the living system that can perform these minimum functions.
  • But on atheism, the living system needs to be simple enough to form by accident in a pre-biotic soup, and in a reasonable amount of time.
  • The minimal functionality in a living system is a achieved by DNA, RNA and enzymes. DNA and RNA are composed of sequences of proteins, which are in turn composed of sequences of amino acids.

Consider the problems of building a chain of 100 amino acids

  • The amino acids must be left-handed only, but left and right kinds are equally abundant in nature. How do you sort out the right-handed ones?
  • The amino acids must be bound together using peptide bonds. How do you prevent other types of bonds?
  • Each link of the amino acid chain needs to be carefully chosen such that the completed chain with fold up into a protein. How do you choose the correct amino acid for each link from the pool of 20 different kinds found in living systems?
  • In every case, a human or other intelligence could solve these problems by doing what intelligent agents do best: making choices.
  • But who is there to make the choices on atheism?

The best current atheistic response to this is to speculate that unobservable and untestable aliens seeded the earth with life.

The problem of the origin of life is not a problem of chemistry, it is a problem of engineering. Every part of car functionality can be understood and described using the laws of physics and chemistry. But an intelligence is still needed in order to assemble the components into a system that has the minimal requirements for a functioning vehicle.

Conclusion

In all three areas, scientists expected that the data would be consistent with atheism. First, scientists expected that life could exist even if the physical constants and ratios were altered. The progress of science said NO. Second, scientists expected that the universe would be eternal. The progress of science said NO. Third, scientists expected that the origin of life would be simple. The progress of science said NO. I think we all need to try to align our beliefs with the progress of science.
