Dr. Craig’s opening speech summary slide

The video of the debate was posted by ReasonableFaith.org – Dr. Craig’s organization. This debate occurred in March 2017 at the University of Dublin, in Ireland.

The video: (91 minutes)

My non-snarky summary is below.

Dr. Craig’s opening speech

Two claims:

1. There are good reasons to think that theism is true.
2. There are not comparably good reasons to think that atheism is true.

Five reasons for God’s existence:

1. The beginning of the universe
– actual infinite past is mathematically impossible
– BGV theorem: any universe that is on balance expanding in its history (like ours) cannot be past eternal

2. Fine-tuning of cosmic quantities and constants
– slight changes to quantities and constants prevent a universe from supporting complex embodied life
– the multiverse response of atheists conflicts with observations, e.g. the Boltzmann Brains problem

3. Objective moral values
– God’s existence is required to ground objective moral values and duties

4. Minimal facts case for the resurrection of Jesus
– there are good reasons to accept the most widely accepted facts about the historical Jesus (empty tomb, appearances, early widespread belief in the resurrection)
– the best explanation of these minimal facts is that God raised Jesus from the dead

5. Experience God directly
– in the absence of any defeaters to belief in God, a person can experience God directly

Dr. Daniel Came’s opening speech

1. The hiddenness of God
– if God wants a personal relationship with us, and a relationship with God would be the greatest good for us
– God ought to reveal himself to us, but he does not  reveal himself to many people, the “non-resistant non-believers”

2. The inductive problem of evil
– many evil events occur that are pointless – there is no morally sufficient reason why God would allow them to occur
– examples: animal suffering, children born with disease, tsunamis
– the theistic response to this is that humans are not in a position to know whether there are morally sufficient reasons, due to our limitations of knowing the consequences
– but this ripple effect defense has 4 possible outcomes, 3 of which don’t do the job of justifying

Dr. Craig’s first rebuttal

1. The hiddenness of God
– God’s goal is not to make his existence known, but to draw them into a love relationship
– it’s speculative that overt displays of God’s existence would draw people to him in a love relationship, they might resent his bullying
– atheist would have to prove that God could draw more people into a love relationship with him by revealing himself more overtly

2. The inductive problem of evil
– as humans, we are not in a position to know for certain that any apparently pointless evil really is pointless
– William Alston article: 6 limitations of human knowing make it impossible to judge that an evil is actually “pointless”
– Dr. Came says that there are 4 possibilities for the ripple effects, and since 3 are bad, it’s likely that there are not morally sufficient reasons for a apparently pointless evil
– it is logically fallacious to assert probability conclusions without knowing the probabilities of those 4 options
– there is actually an argument from evil: since the problem of evil requires an objective standard of good and evil by which to measure, and God is the only possible ground of objective morality, then pressing the problem of evil actually requires the atheist to assume God, in order to ground this objective moral standard

Dr. Came’s first rebuttal

3. Objective moral values
– there are naturalistic theories of moral realism where objective moral duties and objective moral values exist in a naturalistic universe
– I’m not saying that any of them are correct, but there are many theories about object morality in a naturalistic universe

There are naturalistic theories for all of the 5 arguments that Dr. Craig presented. It is Dr. Craig’s responsibility to present those naturalistic theories and prove that they are not as good as his explanations. I’m not going to defend (or even name!) a single naturalistic theory for any of these 5 arguments by Dr. Craig.

Dr. Craig’s explanations for the 5 evidences he gave can’t be admitted, because we have to know how God did something in naturalistic terms before we can know that God did it supernaturally. Explanations are only valid if they are naturalistic.

1. The beginning of the universe
– naturalism explains how the universe expands after it came into being, so that explains how it came into being
– the God explanation, that God created the universe out of nothing, is not admissible, because it is not naturalistic
– how does God, as an unembodied mind interact with the physical world?
– the only agency that we know about is human agents, and we have bodies, so how could God perform actions without having a body?

The theistic hypothesis does not make any predictions, but naturalism makes lots of testable predictions. God could do anything, so he is not constrained and is therefore untestable. We can’t infer God as an explanation in principle because we can’t predict what is more probable if God exists than if he does not.

2. Fine-tuning of cosmic quantities and constants
– the university was not set up to make embodied intelligence plausible, because the vast majority of the universe is hostile to life
– there are models of the multiverse that escape the Boltzmann Brains problem that Dr. Craig raised

Dr. Craig’s second rebuttal

Some of Dr. Craig’s arguments are deductive (e.g. – the beginning of the universe, objective moral values), so that the conclusion follows from the premises if the premises are true. The resurrection passes the standard tests for historical explanations.

1. The beginning of the universe
– the whole point of the argument is that there is no naturalistic explanation for an ultimate beginning of the universe

2. Fine-tuning of cosmic quantities and constants
– the whole point of the argument is that there is no naturalistic explanation for a design of the universe to support life
– he has to prove that intelligences has to be attached to bodies
– human beings are non-physical minds united to physical bodies
– naturalistic attempts to explain mental operations fail
– the arguments prove that unembodied minds exist
– the vast expanse of the universe is required in order to form the galaxies, stars and heavy elements needed for complex life
– why expect that the entire universe should be small, or that life would be everywhere?
– a non-fine-tuned world is more likely in the multiverse, and in a multiverse, we are more likely to have a Boltzmann brain world than a world with complex, embodied life
– Dr. Came has not advanced any naturalistic explanation for the fine-tuning

3. Objective moral values
– non-theistic ethical theories cannot account for the ontological foundations of objective moral values and duties
– atheistic theories of moral realism simply assume objective moral values out of thin air
– it is especially hard to find any basis for objective moral duties in the absence of God

Dr. Came’s second rebuttal

5. Religious experience
– Dr. Craig should not bring up religious experience in a debate where arguments and evidence are central
– people who have dreams, hallucinations and psychotic delusions could appeal to religious experience
– religious experience is by no means universal, and it is possible to doubt it

3. Objective moral values
– there are lots of atheists who hold to objective moral values
– Dr. Craig has to explain how God grounds objective moral values and duties
– Dr. Craig has to explain why atheist moral realist theories don’t work to ground objective moral values and duties

1. The beginning of the universe
– Dr. Craig claims that something can’t come from nothing, that’s not an argument
– there are numerous models that don’t require an absolute beginning of the universe
– Dr. Craig cites the BGV theorem, but Guth (one of the authors) says that only the inflation has a beginning, not the whole universe

Dr. Craig’s conclusion

1. The beginning of the universe
– on theism, there is an efficient cause, but no material cause, for the origin of the universe
– on atheism, there is neither an efficient cause nor a material cause, for the origin of the universe: that’s worse!
– if he thinks that there are models of the universe that don’t require a beginning, then let him name a viable eternal model of the universe
– he never refuted the mathematical argues against an infinite past

2. Fine-tuning of cosmic quantities and constants
– nothing to refute

3. Objective moral values
– God is a better ground for morality than humans, because he is ultimate, and not contingent and arbitrary
– God is a being who is worthy of worship, and therefore command his creatures with moral duties

4. Minimal facts case for the resurrection of Jesus
– nothing to refute

5. Religious experience
– only justified because there are no defeaters to it

1. The hiddenness of God
– atheist has to show that if God’s existence were more obvious, that it would result in more people being drawn to him

2. The inductive problem of evil
– Dr. Came’s argument was logically fallacious, and makes errors in probability theory

Dr. Came’s conclusion

Sometimes, people can’t prove something, but lack of evidence is a justification for doubting it, e.g. – werewolves.

If none of Craig’s arguments work, then it follows that it is not rational to believe that God exists, and it is rational to believe that God does not exist.

Atheists shouldn’t have a burden of proof for what they know, only theists have a burden of proof for what they know.

My thoughts

One quick point. If life were common everywhere then atheists would infer that God wasn’t involved in it. Period. “Life is everywhere, so it’s common, why do we need a designer?” they’d say. I agree with Dr. Came about denouncing religious experience in a formal debate. I don’t like when Dr. Craig brings this up, but I see why he does it – he’s an evangelist, and that’s a good thing, too. I just worry about how it looks to atheists, although it’s good for sincere seekers. I’m not the one on the stage, though, Dr. Craig is.

I think the point about more overt revealing by God would annoy people and make them turn away. Think of how gay people respond to the suggestion that there is anything wrong with them, with rage, vandalism, threats, coercion, attempts to get you to lose your job and business, and using government as a weapon to fine and imprison you. It’s really obvious to me that more God does not mean more love of God. For those who don’t want God, the hiddenness is respect for their choice to put pleasure above the search for truth. (I mean the gay activists – I have great sympathy for people who struggle with same-sex unwanted attractions because they were impacted by a failed bond with their parent of the same sex as they are).

Whenever I meet people like Dr. Came, I always urge them to keep investigating and pursuing truth, because they will find it if they are sincerely seeking after God. Some atheists do sincerely seek God, but I don’t know any who haven’t found him. I’m not sure if that’s because those atheists who claim to be non-resistant and rational are in fact resistant and non-rational, or what the real reason is. If you believe the Bible, all unbelief is non-rational and resistant (see Romans 1). Regarding the werewolves, we don’t have any good arguments for werewolves, we do have good arguments for God. Dr. Came didn’t refute the arguments that Craig raised, nor did his own arguments for atheism work. And there are many, many more arguments (origin of life, Cambrian explosion, habitability-discoverability, molecular machines) that Craig did not raise, too.

Alexander Vilenkin: “All the evidence we have says that the universe had a beginning”

2 Comments

I’ve decided to explain why physicists believe that there was a creation event in this post. That is to say, I’ve decided to let famous cosmologist Alexander Vilenkin do it.

From Uncommon Descent.

Excerpt:

Did the cosmos have a beginning? The Big Bang theory seems to suggest it did, but in recent decades, cosmologists have concocted elaborate theories – for example, an eternally inflating universe or a cyclic universe – which claim to avoid the need for a beginning of the cosmos. Now it appears that the universe really had a beginning after all, even if it wasn’t necessarily the Big Bang.

At a meeting of scientists – titled “State of the Universe” – convened last week at Cambridge University to honor Stephen Hawking’s 70th birthday, cosmologist Alexander Vilenkin of Tufts University in Boston presented evidence that the universe is not eternal after all, leaving scientists at a loss to explain how the cosmos got started without a supernatural creator. The meeting was reported in New Scientist magazine (Why physicists can’t avoid a creation event, 11 January 2012).

[…]In his presentation, Professor Vilenkin discussed three theories which claim to avoid the need for a beginning of the cosmos.

The three theories are chaotic inflationary model, the oscillating model and quantum gravity model. Regular readers will know that those have all been addressed in William Lane Craig’s peer-reviewed paper that evaluates alternatives to the standard Big Bang cosmology.

But let’s see what Vilenkin said.

More:

One popular theory is eternal inflation. Most readers will be familiar with the theory of inflation, which says that the universe increased in volume by a factor of at least 10^78 in its very early stages (from 10^−36 seconds after the Big Bang to sometime between 10^−33 and 10^−32 seconds), before settling into the slower rate of expansion that we see today. The theory of eternal inflation goes further, and holds that the universe is constantly giving birth to smaller “bubble” universes within an ever-expanding multiverse. Each bubble universe undergoes its own initial period of inflation. In some versions of the theory, the bubbles go both backwards and forwards in time, allowing the possibility of an infinite past. Trouble is, the value of one particular cosmic parameter rules out that possibility:

But in 2003, a team including Vilenkin and Guth considered what eternal inflation would mean for the Hubble constant, which describes mathematically the expansion of the universe. They found that the equations didn’t work (Physical Review Letters, DOI: 10.1103/physrevlett.90.151301). “You can’t construct a space-time with this property,” says Vilenkin. It turns out that the constant has a lower limit that prevents inflation in both time directions. “It can’t possibly be eternal in the past,” says Vilenkin. “There must be some kind of boundary.”

A second option explored by Vilenkin was that of a cyclic universe, where the universe goes through an infinite series of big bangs and crunches, with no specific beginning. It was even claimed that a cyclic universe could explain the low observed value of the cosmological constant. But as Vilenkin found, there’s a problem if you look at the disorder in the universe:

Disorder increases with time. So following each cycle, the universe must get more and more disordered. But if there has already been an infinite number of cycles, the universe we inhabit now should be in a state of maximum disorder. Such a universe would be uniformly lukewarm and featureless, and definitely lacking such complicated beings as stars, planets and physicists – nothing like the one we see around us.

One way around that is to propose that the universe just gets bigger with every cycle. Then the amount of disorder per volume doesn’t increase, so needn’t reach the maximum. But Vilenkin found that this scenario falls prey to the same mathematical argument as eternal inflation: if your universe keeps getting bigger, it must have started somewhere.

However, Vilenkin’s options were not exhausted yet. There was another possibility: that the universe had sprung from an eternal cosmic egg:

Vilenkin’s final strike is an attack on a third, lesser-known proposal that the cosmos existed eternally in a static state called the cosmic egg. This finally “cracked” to create the big bang, leading to the expanding universe we see today. Late last year Vilenkin and graduate student Audrey Mithani showed that the egg could not have existed forever after all, as quantum instabilities would force it to collapse after a finite amount of time (arxiv.org/abs/1110.4096). If it cracked instead, leading to the big bang, then this must have happened before it collapsed – and therefore also after a finite amount of time.

“This is also not a good candidate for a beginningless universe,” Vilenkin concludes.

So at the end of the day, what is Vilenkin’s verdict?

“All the evidence we have says that the universe had a beginning.”

This is consistent with the Borde-Guth-Vilenkin Theorem, which I blogged about before, and which William Lane Craig leveraged to his advantage in his debate with Peter Millican.

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, can be eternal into the past. No one denies the expansion of space in our universe, and so we are left with a cosmic beginning. Even speculative alternative cosmologies do not escape the need for a beginning.

Conclusion

If the universe came into being out of nothing, which seems to be the case from science, then the universe has a cause. Things do not pop into being, uncaused, out of nothing. 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.

Now, let’s have a discussion about this science in our churches, and see if we can’t train Christians to engage with non-Christians about the evidence so that everyone accepts what science tells us about the origin of the universe.

Kenosis and the doctrine of the Incarnation in Philippians 2:5-11

The Son of God became flesh and dwelt among us
The Son of God became flesh and dwelt among us

It’s Christmas, so it’s time to see what the Bible says about who Jesus was and what it tells us about the character of God.

Here are the relevant verses in Phil 2:5-11 [NASB]:

5 Have this attitude in yourselves which was also in Christ Jesus,

6 who, although He existed in the form of God, did not regard equality with God a thing to be grasped,

7 but emptied Himself, taking the form of a bond-servant, and being made in the likeness of men.

8 Being found in appearance as a man, He humbled Himself by becoming obedient to the point of death, even death on a cross.

9 For this reason also, God highly exalted Him, and bestowed on Him the name which is above every name,

10 so that at the name of Jesus every knee will bow, of those who are in heaven and on earth and under the earth,

11 and that every tongue will confess that Jesus Christ is Lord, to the glory of God the Father.

Here’s respected New Testament scholar Ben Witherington to help us make sense of it:

Incarnation refers to the choices and acts of a pre-existent divine being, namely the Son of God, that the Son took in order to become a human being. He took on flesh, and became fully, truly human without ceasing to be fully, truly divine. Divinity is not something Jesus acquired later in life, or even after his death and resurrection. According to the theology of Incarnation he had always been the divine Son of God, even before he became Jesus, a human being. Strictly speaking the name Jesus only applies to a human being. It is the name the Son of God acquired once he became a human being in the womb of Mary, a name which he maintains to this day as he continues to be a human being.

[…]When I try and explain the incarnation to my students I deliberately choose to use the phrase divine condescension. What do I mean by this? Put another way, if there is going to be a corporate merger between a divine being and a human nature, then the divine side of the equation must necessarily limit itself, take on certain limitations, in order to be truly and fully human. The next question is…. what does it mean to be fully human? It means to have limitations of time and space and knowledge and power, and of course being mortal. Jesus exhibited all these traits. He was even tempted like us in every respect, but he avoided sin. What we should deduce from this is sinning is not a necessary part of being truly human. Yes, it is a trait of all fallen humans, but no, it is not how God made us in the first place. It is not necessary to sin in order to be truly or fully human.

[…]While the hymn is clear that the Son was ‘in very nature God’ at the same time he chose before he became human not to take advantage of his divine prerogatives. What were those? I call them the omnis– omniscience, omnipotence, omnipresence.

[…]And here I think is what Paul is driving at when he says ‘have this mind in yourselves that was also in Christ Jesus’. It says that he ‘humbled himself’. Now contrary to what the world may think humility has nothing to do with feelings of low self-esteem. It has nothing to do with feelings of low self-worth. If Jesus is the model of true humility, it can’t have anything to do with those things, because Jesus surely was the one person who walked this earth who did not have such feelings, did not have an identity crisis, and so on. Humility is the posture of a strong person who steps down to serve others, as Jesus did.

This IVP commentary on Bible Gateway talks more about what this “divine condescension” means to us, using that passage from Philippians:

Christ’s selflessness for the sake of others expressed itself in his emptying himself by taking the “form” of a slave. Historically, far too much has been made of the verb “emptied himself,” as though in becoming incarnate he literally “emptied himself” of something. However, just asharpagmos requires no object for Christ to “seize” but rather points to what is the opposite of God’s character, so Christ did not empty himself of anything; he simply “emptied himself,” poured himself out, as it were. In keeping with Paul’s ordinary usage, this is metaphor, pure and simple. What modifies it is expressed in the phrase that follows; he “poured himself out by taking on the ‘form’ of a slave.”

Elsewhere this verb regularly means to become powerless or to be emptied of significance (hence the NIV’s made himself nothing; cf. KJV, “made himself of no reputation”). Here it stands in direct antithesis to the “empty glory” of verse 3 and functions in the same way as the metaphorical “he became poor” in 2 Corinthians 8:9. Thus, as in the “not” side of this clause (v. 6b), we are still dealing with the character of God as revealed in the mindset and resulting activity of the Son of God. The concern is with divine selflessness: God is not an acquisitive being, grasping and seizing, but self-giving for the sake of others.

I think it’s important to be clear that Jesus didn’t give up anything of his divine attributes by becoming a man. Rather, he added a human nature to his divine nature. The humility is because he came to serve  others.

You can see a nice quick video of this doctrine being defended by famous philosophical theologian William Lane Craig:

I think that it is important for us to emphasize the doctrine of the Incarnation at Christmas, in order to correct the grasping and seizing that is so widespread. The really interesting thing about Christmas is the Incarnation, and what it tells us about God and us. It tells us that we have value, because Jesus loved us. But it also says that following Jesus means being humble and being a servant to others. It means pouring yourself out to others in order to serve them. And these obligations are not metaphorical – they are rooted in the historical facts. This is the way the world is as a matter of fact, although certainly we have freedom to rebel against it.

For those looking for defenses to the doctrine of the Incarnation, you can find a chapter on it by Paul Copan in the book “Contending With Christianity’s Critics“. That’s for intermediate readers. For advanced readers you can look for a chapter in “The Cambridge Companion to Christian Philosophical Theology“, edited by Charles Taliaferro and Chad Meister, and published by Cambridge University Press.
