…integrating Christian faith and knowledge in the public square

The kalam cosmological argument defended in a peer-reviewed science journal

Here’s the peer-reviewed article. It appears in a scientific journal focused on astrophysics.

Here’s the abstract:

Both cosmology and philosophy trace their roots to the wonder felt by the ancient Greeks as they contemplated the universe. The ultimate question remains why the universe exists rather than nothing. This question led Leibniz to postulate the existence of a metaphysically necessary being, which he identified as God. Leibniz’s critics, however, disputed this identification, claiming that the space-time universe itself may be the metaphysically necessary being. The discovery during this century that the universe began to exist, however, calls into question the universe’s status as metaphysically necessary, since any necessary being must be eternal in its existence. Although various cosmogonic models claiming to avert the beginning of the universe predicted by the standard model have been and continue to be offered, no model involving an eternal universe has proved as plausible as the standard model. Unless we are to assert that the universe simply sprang into being uncaused out of nothing, we are thus led to Leibniz’s conclusion. Several objections to inferring a supernatural cause of the origin of the universe are considered and found to be unsound.

The whole text of the article is posted online here.

Here’s an excerpt in which the author, Dr. William Lane Craig, explains the Big Bang cosmology:

The monumental significance of the Friedman-Lemaitre model lay in its historization of the universe. As one commentator has remarked, up to this time the idea of the expansion of the universe “was absolutely beyond comprehension. Throughout all of human history the universe was regarded as fixed and immutable and the idea that it might actually be changing was inconceivable.”{8} But if the Friedman-Lemaitre model were correct, the universe could no longer be adequately treated as a static entity existing, in effect, timelessly. Rather the universe has a history, and time will not be matter of indifference for our investigation of the cosmos. In 1929 Edwin Hubble’s measurements of the red-shift in the optical spectra of light from distant galaxies,{9} which was taken to indicate a universal recessional motion of the light sources in the line of sight, provided a dramatic verification of the Friedman-Lemaitre model. Incredibly, what Hubble had discovered was the isotropic expansion of the universe predicted by Friedman and Lemaitre. It marked a veritable turning point in the history of science. “Of all the great predictions that science has ever made over the centuries,” exclaims John Wheeler, “was there ever one greater than this, to predict, and predict correctly, and predict against all expectation a phenomenon so fantastic as the expansion of the universe?”{10}

As a GTR-based theory, the Friedman-Lemaitre model does not describe the expansion of the material content of the universe into a pre-existing, empty, Newtonian space, but rather the expansion of space itself. This has the astonishing implication that as one reverses the expansion and extrapolates back in time, space-time curvature becomes progressively greater until one finally arrives at a singular state at which space-time curvature becomes infinite. This state therefore constitutes an edge or boundary to space-time itself. P. C. W. Davies comments,

An initial cosmological singularity . . . forms a past temporal extremity to the universe. We cannot continue physical reasoning, or even the concept of spacetime, through such an extremity. . . . On this view the big bang represents the creation event; the creation not only of all the matter and energy in the universe, but also of spacetime itself.{11}

The popular expression “Big Bang,” originally a derisive term coined by Fred Hoyle to characterize the beginning of the universe predicted by the Friedman-Lemaitre model, is thus potentially misleading, since the expansion cannot be visualized from the outside (there being no “outside,” just as there is no “before” with respect to the Big Bang).{12}

The standard Big Bang model thus describes a universe which is not eternal in the past, but which came into being a finite time ago. Moreover,–and this deserves underscoring–the origin it posits is an absolute origin ex nihilo. For not only all matter and energy, but space and time themselves come into being at the initial cosmological singularity. As Barrow and Tipler emphasize, “At this singularity, space and time came into existence; literally nothing existed before the singularity, so, if the Universe originated at such a singularity, we would truly have a creation ex nihilo.“{13}

[…]On such a model the universe originates ex nihilo in the sense that at the initial singularity it is true that There is no earlier space-time point or it is false that Something existed prior to the singularity.

Every theist should be able to understand and defend this argument. It is a scientific refutation of materialism, and it is supported by six lines of scientific evidence – all of which emerged as science has progressed.

Scientific evidence:

  1. Einstein’s theory of general relativity (GTR)
  2. the red-shifting of light from distant galaxies implies an expanding universe
  3. the cosmic background radiation (which also disproves the oscillating model of the universe)
  4. the second law of thermodynamics applied to star formation theory
  5. hydrogen-helium abundance predictions
  6. radioactive element abundance predictions

Those are the scientific discoveries that have led us to the beginning of the universe, which support’s Dr. Craig’s argument.

Here’s a re-cap of the three main evidences for the Big Bang cosmology from Caltech. (Numbers 2, 3 and 5 from the list above)

Excerpt:

Until the early 1900s, most people had assumed that the universe was fixed in size. New possibilities opened up in 1915, when Einstein formulated his famous general relativity theory that describes the nature of space, time, and gravity. This theory allows for expansion or contraction of the fabric of space. In 1917, astronomer Willem de Sitter applied this theory to the entire universe and boldly went on to show that the universe could be expanding. Aleksandr Friedmann, a mathematician, reached the same conclusion in a more general way in 1922, as did Georges Lemaître, a cosmologist and a Jesuit, in 1927. This step was revolutionary since the accepted view at the time was that the universe was static in size. Tracing back this expanding universe, Lemaître imagined all matter initially contained in a tiny universe and then exploding. These thoughts introduced amazing new possibilities for the universe, but were independent of observation at that time.

Why Do We Think the Big Bang Happened?

Three main observational results over the past century led astronomers to become certain that the universe began with the big bang. First, they found out that the universe is expanding—meaning that the separations between galaxies are becoming larger and larger. This led them to deduce that everything used to be extremely close together before some kind of explosion. Second, the big bang perfectly explains the abundance of helium and other nuclei like deuterium (an isotope of hydrogen) in the universe. A hot, dense, and expanding environment at the beginning could produce these nuclei in the abundance we observe today. Third, astronomers could actually observe the cosmic background radiation—the afterglow of the explosion—from every direction in the universe. This last evidence so conclusively confirmed the theory of the universe’s beginning that Stephen Hawking said, “It is the discovery of the century, if not of all time.”

The article goes into detail about each of these three evidences.

This is the kind of evidence I expect all Christian theists to be using when discussing the question of whether God exists. Scientific evidence. When talking to non-Christians, we first need to show that we understand science, because science is a reliable and respected way of getting knowledge about the universe. Non-Christians do not accept the Bible, but they do accept science, so we begin evangelism with science. Science (experimental, testable, repeatable science) should set limits on what anyone can believe – including non-Christians, who might otherwise not be inclined to listen to Bible verses and theology.

The Big Bang is not compatible with atheism

According to the Secular Humanist Manifesto, atheism is committed to an eternally existing universe, (See the first item: “Religious humanists regard the universe as self-existing and not created.”). If something non-material brought all existing matter into being, that would be a supernatural cause, and atheists deny that anything supernatural exists. The standard Big Bang theory requires that all the matter in the universe come into being out of nothing. This falsifies eternal models of the universe, which are required by the atheistic worldview.

You should definitely print out both articles and get familiar with the arguments and the evidence. I have tried this argument out on atheists, and the response I usually get is that scientific discoveries will soon emerge that falsifies all of these six scientific discoveries. That sounds more like faith than reason to me. And we have to make it clear to others who are still deciding that there is a conflict between science and religion. Just not the one they’re expecting. Let’s make our decisions about what to believe based on what science is telling us today. Let’s hold accountable people who want to have a worldview that is based on speculations.

New discovery confirms Big Bang, and is direct evidence for cosmic inflation

From the UK Telegraph.

Excerpt:

Space-time ripples left over from the Big Bang have been picked up for the first time by Harvard scientists.

Astrophysicists have been hunting for ‘primordial gravitational waves’ since they were predicted by Albert Einstein’s theory of general relativity in 1916.

Today, after days of rumour and speculation, scientists from the Harvard-Smithsonian Centre announced they had recorded the first direct evidence of gravitational waves rippling through the infant universe.

“The implications for this detection stagger the mind,” said project leader Jamie Bock. “We are measuring a signal that comes from the dawn of time.”

Our universe burst into existence 13.8 billion years ago. Fractions of a second later, space and time were created, expanding exponentially in an episode known as ‘inflation’.

It was theorized that inflation should also produce gravitational waves – ripples in space-time which spread throughout the universe.

“Think of the ripples you see when you throw a stone into a pond,” said Professor Martin Hendry of the department of Physics and Astronomy at the Univesity of Glasgow.

“But these aren’t ripples on the surface of the water, they are gravitational waves emitted billions of years ago, rippling through the fabric of space and time itself, in the universe’s earliest moments.

“We always suspected they were still washing about but we haven’t been able to detect them.

[…]The signal was found using a specialised telescope called Bicep (Background Imaging of Cosmic Extragalactic Polarization) at the South Pole.

It scans the sky at microwave frequencies, where it picks up light energy from slightly after the Big Bang – around 380,000 years later. Scientists have been searching for tiny ripples in this light which would show it is being slightly stretched by gravitational waves.

We have had a string of solid, recent scientific discoveries that support the idea that the universe came into existence at some point in the finite past, as follows:

  • Einstein’s theory of general relativity, and the scientific confirmation of its accuracy
  • measurements of the cosmic microwave background radiation
  • red-shifting of light from galaxies moving away from us
  • radioactive element abundance predictions (from supernovae)
  • helium/hydrogen abundance predictions (nuclear fusion)
  • star formation and stellar lifecycle theories
  • the second law of thermodynamics

This new discovery is building on #2 above – the cosmic microwave background radiation.

What came into being at the moment of creation?

As the article states, space was created and time began at the first moment.

  1. There was no space causally prior to the universe beginning to exist
  2. There was no time causally prior to the universe beginning to exist
  3. There was no matter causally prior to the universe beginning to exist

All of these things began to exist at the first moment.

What can we infer about the cause?

So, space, time, and matter began to exist. What could have caused them to begin to exist?

  1. Whatever causes the universe to appear is not inside of space, because there was no space causally prior to the creation event. The cause must therefore be non-physical, because physical things exist in space.
  2. Whatever causes the universe to appear is not bound by time (temporal). It never began to exist. There was no passage of time causally prior to the big bang, so the cause of the universe did not come into being. The cause existed eternally.
  3. And the cause is not material. All the matter in the universe came into being at the first moment. Whatever caused the universe to begin to exist cannot have been matter, because there was no matter causally prior to the big bang.

So what could the cause be? Dr. William Lane Craig notes that we are only familiar with two kinds of non-material realities:

  1. Abstract objects, like numbers, sets and mathematical relations
  2. Minds, like your own mind

Now, abstract objects don’t cause of any effects in nature. But we are very familiar with the causal capabilities of our own minds – just raise your own arm and see! So, by process of elimination, we are left with a mind as the cause of the universe. As Sherlock Holmes says, “When you have eliminated the impossible, whatever remains, however improbable, must be the truth.

This cause created the entire physical universe. The cause of this event is therefore supernatural, because it brings nature into being and is not inside of nature itself. The cause of the universe violates the law of conservation of matter is therefore a miracle. And when we do our science, we find evidence of it.

William Lane Craig lectures against naturalism at the University of St. Andrews, Scotland

Note: if you have heard Dr. Craig’s arguments against naturalism before, then I recommend jumping right to the Q&A time, which starts 72 minutes in.

About Dr. William Lane Craig:

William Lane Craig (born August 23, 1949) is an American analytic philosopher, philosophical theologian, and Christian apologist. He is known for his work on the philosophy of time and the philosophy of religion, specifically the existence of God and the defense of Christian theism. He has authored or edited over 30 books including The Kalam Cosmological Argument (1979), Theism, Atheism and Big Bang Cosmology(co-authored with Quentin Smith, 1993), Time and Eternity: Exploring God’s Relationship to Time (2001), and Einstein, Relativity and Absolute Simultaneity (co-edited with Quentin Smith, 2007).

Craig received a Bachelor of Arts degree in communications from Wheaton College, Illinois, in 1971 and two summa cum laudemaster’s degrees from Trinity Evangelical Divinity School in Deerfield, Illinois, in 1975, in philosophy of religion and ecclesiastical history. He earned a Ph.D. in philosophy under John Hick at the University of Birmingham, England in 1977 and a Th.D. underWolfhart Pannenberg at the University of Munich, Germany in 1984.

Here is the full lecture with Q&A: (2 hours)

Summary:

  • Naturalism defined: the physical world (matter, space and time) is all that exists
  • Dr. Craig will present 7 reasons why naturalism is false
  • 1) the contingency argument
  • 2) the kalam cosmological argument
  • 3) the fine-tuning of the universe for intelligent life
  • 4) the moral argument
  • 5) the ontological argument
  • 6) the resurrection of Jesus
  • 7) religious experience

The Q&A time starts around 1:12:00.

Dr. Craig does mention an 8th argument early in the Q&A – the argument from the non-physicality of mental states (substance dualism), which is an argument that I find convincing, because a materialist conception of mind is not compatible with rationality, consciousness and moral agency. He gets a couple of questions on the moral argument early on – one of them tries to put forward an evolutionary explanation for “moral” behaviors. There’s another question the definition of naturalism. There is a bonehead question about the non-existence of Jesus based on a Youtube movie he saw – which Craig responds to with agnostic historian Bart Ehrman’s book on that topic. There’s a question about God as the ground for morality – does morality come from his will or nature. Then there is a question about the multiverse, which came up at the physics conference Dr. Craig attended the day before. There is a good question about the Big Bang theory and the initial singularity at time t=0. Another good question about transfinite arithmetic, cardinality and set theory. One questioner asks about the resurrection argument. The questioner asks if we can use the origin of the disciples belief as an argument when other religions have people who are willing to die for their claims. One of the questioners asks about whether the laws of nature break down at 10^-43 after the beginning of the universe. There is a question about the religious experience argument, and Craig has the opportunity to give his testimony.

I thought that the questions from the Scottish students and faculty were a lot more thoughtful and respectful than at American colleges and universities. Highly recommended.

William Lane Craig debates Peter Millican: Does God Exist? Video, audio and summary

The audio of the debate can be downloaded from Apologetics 315.

Description:

Christian philosopher William Lane Craig debates atheist Peter Millican on the topic: Does God Exist?The debate was organised by the Philosophy Society at Birmingham University on October 21, 2011 for the Reasonable Faith tour. The Tour was co sponsored by UCCF, Damaris and Premier Christian Radio (audio via their Unbelievable podcast). Want to hear every audio debate by William Lane Craig? Check out the audio debate feed here.

Full Debate MP3 Audio here(2hr 23min)

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:

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.
