Neil Shenvi lectures on the evidence for the resurrection of Jesus

The lecture was given to the Intervarsity group at Duke University.

Speaker bio:

As it says on the main page, my name is Neil Shenvi; I am currently a research scientist with Prof. Weitao Yang at Duke University in the Department of Chemistry. I was born in Santa Cruz, California, but grew up in Wilmington, Delaware. I attended Princeton University as an undergraduate where I worked on high-dimensional function approximation with Professor Herschel Rabitz. I became a Christian in Berkeley, CA where I did my PhD in Theoretical Chemistry at UC – Berkeley with Professor Birgitta Whaley. The subject of my PhD dissertation was quantum computation, including topics in quantum random walks, cavity quantum electrodynamics, spin physics, and the N-representability problem. From 2005-2010, I worked as a postdoctoral associate with Prof. John Tully at Yale where I did research into nonadiabatic dynamics, electron transfer, and surface science.

Here’s the lecture:

The MP3 file of the lecture is here for those who prefer audio.

For those who don’t have the bandwidth to watch or listen to the lecture, here’s a paper that has similar information that Neil wrote.

Excerpt:

The earliest followers of Jesus were emphatic about the centrality of the Resurrection to the gospel, the core message of Christianity.  To those in the city of Corinth who were questioning the necessity and perhaps even the factuality of the Resurrection, the apostle Paul wrote: ‘if Christ has not been raised, your faith is futile; you are still in your sins’ (1. Cor. 15:17).  The reason for this connection is clear if we understand the gospel itself.  The gospel of Jesus does not say: “Here are the rules; if you obey them, God will bless you.  Otherwise, God will curse you.”  Rather the gospel says: “You have broken God’s rules and deserve God’s curse.  But Jesus was crucified for your sins and raised to life as a declaration that payment was made in full.  You can now be accepted by God not on the basis of what you have done but on the basis of what Jesus has done for you.”  Without the Resurrection, says Paul, Christians would have no assurance that they are accepted by God or that Jesus has truly paid their debt in full.  Consequently, the factuality of the Resurrection is of utmost importance to Christians.

[…]Before we can examine the evidence, we must first assess the reliability of the New Testament documents since these provide us with the most accurate information we have about the life and ministry of Jesus.  One of the easiest ways to discount the historicity of the Resurrection and of Christianity in general is to claim that the records we have of Jesus’ life are legendary rather than historical.  The main problem with such claims is that they run counter to a massive amount of evidence that we have for the general historical reliability of the New Testament.

[…]Modern critical scholars –such as the participants of the widely known Jesus Seminar- assume that only a small fraction of the New Testament is historical and that the majority of the material is either fictional or only loosely based on historical facts.  To determine what material is historical, they use three major criteria 1) the criterion of multiple attestation 2) the criterion of embarrassment 3) the criterion of dissimilarity.  If a saying or action recorded in the New Testament gospels meets one or more of these criteria, it is considered more likely –though by no means certain- that this material is historical.  Obviously, as an evangelical Christian, I believe that there are serious flaws in the assumptions made by these scholars.  But as we will see below, the Resurrection accounts meet all three of these major criteria of historicity.

[…]Lastly, I think it is very important to consider what alternative, naturalistic explanations have been put forward to explain the Resurrection.  As I mentioned before, many skeptics assume that there must be some plausible, naturalistic explanation for the Resurrection without ever considering the evidence.

Previously, I’ve featured Neil’s defense of objective morality, his lecture on science and religion and his introduction to quantum mechanics, all of which were really popular. These are easy to understand, but substantive, too.

Physicist Victor Stenger debates William Lane Craig: Does God Exist?

This debate took place on March 1, 2010 at Oregon State University.

In this debate, Victor Stenger does affirm his belief that the universe could be eternal in his second rebuttal (1:02:30), thus denying the standard Big Bang cosmology. He also denies the law of conservation of energy and asserts that something can come from nothing in his concluding speech (1:33:50). He also caused the audience to start laughing when he said that Jesus was not moral and supported slavery. There is almost no snark in this summary. Instead, I quoted Dr. Stenger verbatim in many places. I still think that it is very entertaining even without the snarky paraphrasing.

The debate includes 30 minutes of Q&A with the students.

Here is the MP3 file for the audio.

Here’s the video of the debate:

Dr. Craig’s opening speech:

  • The ontological argument
  • The contingency argument
  • The cosmological argument
  • The moral argument
  • The resurrection of Jesus (3-fact version)
  • Religious experience

Dr. Stenger’s opening speech:

  • There is no scientific evidence for God’s existence in the textbooks
  • There is no scientific evidence for God acting in the universe
  • God doesn’t talk to people and tell them things they couldn’t possibly know
  • The Bible says that the Earth is flat, etc.
  • There is no scientific evidence that God answers prayers
  • God doesn’t exist because people who believe in him are ignorant
  • Human life is not optimally designed and appears to be the result of a blind, ad hoc evolutionary process
  • The beginning of the universe is not ordered (low entropy) but random and chaotic
  • It’s theoretically possible that quantum tunneling explains the origin of the universe
  • The laws of physics are not objectively real, they are “our inventions”
  • Regarding the beginning of the universe, the explanation is that something came from nothing*
  • Nothing* isn’t really nothing, it is “the total chaos that we project existed just before the big bang”
  • If something has no structure, then “it is as much nothing as nothing can be”
  • Consciousness is explainable solely on the basis of material processes
  • There are well-informed, rational non-believers in the world and God would not allow that

Dr. Craig’s first rebuttal:

Stenger’s argument that there is no objective evidence for God’s existence:

  • First, it is not required that God rely only on objective evidence in order to draw people to himself (Alvin Plantinga)
  • Second, God is not required to provide evidence to everyone, only to the people who he knows would respond to him
  • Third, Craig gave lots of objective evidence, from science, history and philosophy
  • Stenger asks for certain evidence (answered prayers, prophecy, etc.), but Craig presented the evidence we have

Stenger’s argument that the balance of energy is zero so “nothing” exists:

  • if you have the same amount of assets and liabilities, it doesn’t mean that nothing exists – your assets and liabilities exist
  • Christopher Isham says that there needs to be a cause to create the positive and negative energy even if they balance
  • the quantum gravity model contradicts observations
  • the vacuum is not the same as nothing, it contains energy and matter
  • the BVG theorem proves that any universe that is expanding must have a beginning

Stenger’s argument that mental operations can be reduced to physical operations:

  • mental properties are not reducible to physical properties
  • epiphenomenalism: is incompatible with self-identity over time
  • epiphenomenalism: is incompatible with thoughts about other things
  • epiphenomenalism: is incompatible with free will
  • substance dualism (mind/body dualism) is a better explanation for our mental experience
  • God is a soul without a body
Dr. Stenger’s first rebuttal:

Craig’s cosmological argument:

  • Craig’s premise is “everything has a cause”, but quantum mechanics has causeless events
  • There are speculative theories about how something could have come into being uncaused out of nothing
  • “I don’t know of a single working cosmologist today who believes there was a singularity prior to the Big Bang”
  • “If there wasn’t a singularity then there’s no basis for arguing that time began at that point”
  • “There’s no reason from cosmology that we know of that the universe can’t be eternal”
  • “When I talk about an eternal universe, I mean a universe that has no beginning or end”
  • The Hartle-Hawking model doesn’t have a beginning
  • “There was no violation of energy conservation by having a universe coming from nothing”
  • “The universe could have come from a previous universe for example or even just from a region of chaos”
  • The paper by Vilenkin is counteracted by other papers (he doesn’t specify which ones)

Craig’s moral argument:

  • Dr. Craig is arguing from ignorance
  • But morality can be decided by humanity just like governments pass laws, and that’s objective
  • Dr. Craig has too little respect for the human intellect
  • I don’t need to tell me that slavery is wrong
  • The Bible supports slavery
  • Atheists can behave as good as theists
  • Morality just evolved naturally as an aid to survival

Craig’s resurrection argument:

  • No Roman historians wrote about the execution of Jesus but none of them did
  • The empty tomb is doubtful because it is only mentioned in the gospels, not by Paul
  • John Dominic Crossan says there was no empty tomb
  • Christianity only survived because the Roman empire thought that they were useful

Dr. Craig’s second rebuttal:

Craig’s cosmological argument:

  • There is no reason to prefer an indeterministic interpretation of quantum mechanics
  • Dr. Stenger himself wrote that deterministic interpretations of quantum mechanics are possible
  • The vacuum in quantum mechanics is not nothing
  • The quantum vacuum he proposes cannot be eternal
  • The cosmological argument does not require a singularity
  • The Hartle-Hawking model is from 1983
  • Hawking says that there is a beginning of space and time after that model
  • The Hartle-Hawking model does still have a beginning of time – the model is not eternal
  • The BVG theorem that requires a beginning for expanding universes is widely accepted among cosmologists

Craig’s moral argument:

  • Stenger redefined objective to mean that most people agree with it – but that’s not what objective means
  • Objective means right and wrong whether anyone accepts it or not
  • Richard Dawkins himself says that on atheism there is “no evil and no good” – why is he wrong?
  • Even Dr. Stenger says that morality is the same as passing laws – it’s arbitrary and varies by time and place
  • But on his view, right and wrong are the same as deciding which side of the road to drive on
  • But somethings really are right and some things are really wrong

Craig’s resurrection argument:

  • Josephus is a Roman historian and he wrote about Jesus, for example
  • There were four biographies of Jesus are the best sources for his life
  • The scholars that Stenger mentioned are on the radical fringe

Dr. Stenger’s second rebuttal:

Knowledge and the burden of proof:

  • Dr. Craig has to bear the burden of proof, not me – because his claim is more “extravagant”
  • “I don’t have to prove that a God was not necessary to create the universe”
  • “I don’t have to prove that a God did not design the universe and life”
  • “I don’t have to prove that the universe did not have a beginning”
  • “I don’t have to prove that God did not provide us with our moral sense”
  • There are a lot of books written about how morality evolved naturally
  • “I don’t have to prove that the events surrounding the supposed resurrection of Jesus did not take place”
  • Bart Ehrman says that the gospels are generally unreliable (Note: Ehrman accepts all 3 of Craig’s minimal facts)
  • Just because people are willing to die for a cause, does not make their leader God, e.g. – the Emperor of Japan

Aesthetic concerns about the universe:

  • I don’t like dark matter and I wouldn’t have made the universe with dark matter
  • I don’t like the doctrine of penal substitution
  • I don’t like the doctrine of original sin
  • I don’t like the heat death of the universe

Dr. Craig’s conclusion:

The case for atheism:

  • Dr. Stenger had two arguments and he has to support his premises
  • Dr. Craig addressed his two arguments and each premise and Dr. Stenger never came back on it

The contingency argument:

  • Dr. Stenger has dropped the refutation of this argument

The cosmological argument:

  • The theoretical vacuum he proposes cannot be eternal

The moral argument:

  • He asserts that things are wrong, but there is no grounding for that to be objective on atheism

The resurrection of Jesus:

  • There are surveys of scholars on the empty tomb and 75% of them agree with it
  • Bart Ehrman agrees with all 3 of the minimal facts that Dr. Craig presented
  • Ehrman’s objection to the resurrection is not historical: he’s an atheist – he thinks miracles are impossible

Religious experience:

  • No response from Dr. Stenger

Dr. Stenger’s conclusion

The cosmological argument:

  • “I argued that we have very good physical reasons to understand how something can come from nothing”
  • “There is a natural tendency in the universe… to go from.. simpler thing to the more complicated thing”
  • The transition from a vapor to a liquid to ice shows how something could come from nothing
  • “It cannot be proven that the universe had a beginning”

The moral argument:

  • Objective morality, which is independent of what people think, could be developed based on what people think
  • “Jesus himself was not a tremendously moral person… he had no particular regard for the poor… he certainly supported slavery… he was for the subjugation of women” (audience laughter)

The resurrection argument:

  • Bart Ehrman says that the majority of the gospels are unreliable

Religious experience:

  • I don’t see any evidence that there is anything more to religious experience than just stuff in their heads

God’s purpose of the world should be to make people feel happy:

  • God could have made people feel happier
  • God could have made people not die
  • God could could have made the universe smaller: it’s too big
  • God could have made it possible for humans to live anywhere “even in space”

Are atheists paying attention to the weightiest demands of the moral law?

J. Warner Wallace looks at what Jesus says the most important commandment is, and then asks whether atheists can be justified morally if Jesus is right.

He writes:

I was an atheist for the first thirty-five years of my life. While I was a committed (and often aggressive) non-believer, most people who knew me would probably have described me as a “nice guy”. My behavior wasn’t all that different than many of my Christian friends. I worked with many other atheist police officers. We were often suspicious of the Christians in our midst and the people we arrested who claimed to be Christians. Even as atheists we were familiar with Jesus’ directive to “love your neighbor as yourself.” My partner, Tim, used to say, “If there is a good God and a good Heaven, I think I will be there when it’s all over. I’m a good person. I try to ‘do the right thing’. I’m not a bad guy; I put bad people in jail. So I’m not worried about it.” Tim held a “works based” moral worldview and he was sure his good deeds would earn him a spot in Heaven if he was wrong about the existence of God. But Tim (and I) were unfamiliar with Jesus’ teaching in its full context, and now, years later as a Christian, I’ve come to understand why the first part of the “Greatest Command” is even more important than the second.

When approached by a skeptic, Jesus affirmed the greatest commandments of God in the following way:

Matthew 22:35-40
One of them, a lawyer, asked Him a question, testing Him, “Teacher, which is the great commandment in the Law?” And He said to him, “‘You shall love the Lord your God with all your heart, and with all your soul, and with all your mind.’ This is the great and foremost commandment. The second is like it, ‘You shall love your neighbor as yourself.’ On these two commandments depend the whole Law and the Prophets.”

Most unbelievers recognize the value of the second half of this command (“You shall love your neighbor as yourself”) but deny the value of the first part (“‘You shall love the Lord your God with all your heart, and with all your soul, and with all your mind.”) There’s a reason, however, why Jesus listed these two commands in this specific order. The first command (loving God) is the “great and foremost commandment” because it is required to achieve the second command (loving others). You can’t truly do the right thing unless you understand the relationship between these two commands:

Read the rest at Cold Case Christianity.

I’ve made the same point here many times, but I have never been an atheist and I don’t make the point in the same winsome way that Wallace does.

I think his post is worth sending along to any atheists you may know who think themselves justified. I think it is a mistake for people to derive their own version of morality based on the time and place where they are, and then think that picking and choosing the parts they like will justify them with God. Remember, a recent survey of atheists found that 97% of them favor abortion rights. I think this is consistent with the atheist view that there are no human rights, including a right to life. Moreover, in my experience, I have found that most atheists have no problem with the government stomping all over the consciences of Christians when it comes to things like gay rights. It’s important to show them that there is a standard independent of their personal opinions, justifications and rationalizations.

William Lane Craig debates Peter Atkins: Does God Exist?

Apologetics 315 posted the video of a debate from the Reasonable Faith speaking tour in the UK:

This is a must-see debate. It was extremely fun to watch.

Details:

On Wednesday 26th October 2011 William Lane Craig debated Peter Atkins on the topic: Does God Exist? This debate took place at the University of Manchester  as part of the UK Reasonable Faith Tour with William Lane Craig. The debate was chaired by Christopher Whitehead, Head of Chemistry School at the University. Post-debate discussion was moderated by Peter S Williams, Philosopher in Residence at the Damaris Trust, UK.

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 in 1984.

Dr. Peter Atkins:

Peter William Atkins (born 10 August 1940) is a British chemist and former Professor of Chemistry at the University of Oxford and a Fellow of Lincoln College. He is a prolific writer of popular chemistry textbooks, including Physical ChemistryInorganic Chemistry, and Molecular Quantum Mechanics. Atkins is also the author of a number of science books for the general public, including Atkins’ Molecules and Galileo’s Finger: The Ten Great Ideas of Science.

Atkins studied chemistry at the University of Leicester, obtaining a bachelor’s degree in chemistry, and – in 1964 – a PhD for research into electron spin resonance spectroscopy, and other aspects of theoretical chemistry. Atkins then took a postdoctoral position at the UCLA as aHarkness Fellow of the Commonwealth fund. He returned to Oxford in 1965 as fellow and tutor of Lincoln College, and lecturer in physical chemistry (later, professor of physical chemistry).

You can get the audio of the debate here, along with links to their previous debate from 1998. This debate is accessible and understandable to novice-level Christians.

I am happy when debates like this come out. I have friends who are Christians who doubt the importance of apologetics in evangelism, because they don’t think that apologists can prove anything or win arguments. I have friends who are skeptical of using arguments that assume a 14-billion year old universe, because they think that the Big Bang is compatible with atheism (!). I have friends who think that philosophical arguments have no persuasive force. I have friends who think that nothing can be proven from history, beyond a reasonable doubt. I have co-workers who ask me whether anyone wins these debates. I think that this debate answers all of those questions.

This debate clearly shows why Christians should not shy away from studying science, philosophy and history. We will not discover anything that harms Christian theism by thinking logically and by looking at the evidence. To the contrary, it is the atheist who makes war on the progress of science, and who is forced to resist the clear experimental evidence, and to resort to baseless speculations and blind faith. If you want to see a good debate with an intelligent atheist, I recommend watching the debate between William Lane Craig and Peter Millican instead. But if you want to see a really, really overwhelming defeat for atheism, watch this debate. It is very clear at the end of this debate why Richard Dawkins refused to debate William Lane Craig at Oxford.

SUMMARY OF THE OPENING SPEECHES

I only had time to summarize the first two speeches. Keep in mind that Dr. Craig always shines in his rebuttals, and this debate is no different. So you’ll want to watch those rebuttals. Dr. Atkins literally says in this debate in his first rebuttal “There was nothing here originally. There is nothing here now. But it is an interesting form of nothing which seems to be something.” And the audience laughs nervously. This debate is like that. You will see a clear winner and clear loser in this debate. This fight is decided by knockout.

William Lane Craig opening speech:

1. the origin of the universe
2. the moral argument
3. the resurrection of Jesus

Peter Atkins opening speech:

1. Dr. Craig is stupid, lazy and evil:
– Dr. Craig’s arguments are old: from the 11th century! Old arguments can’t be true
– Dr. Craig is just asserting that “God did it” because he is lazy
– Dr. Craig feels pressured to agree with the theistic majority
– Dr. Craig needs a psychological crutch to comfort him
– Dr. Craig is fearful of death
– Dr. Craig is just wishing for an eternal life of bliss
– Dr. Craig is driven by his heart, and not by his head

2. Origin of the universe:
– Maybe the universe is eternal and has no beginning – we don’t know
– Maybe mommy universes can give birth to daughter universes
– It is naive to think that a cause is needed to cause the creation of the universe from nothing
– Science is just about to show how it is possible that something appears out of nothing without cause
– Some scientists have already begun to speculate about about how something can come into being out of nothing
– Maybe nothing is not really nothing, but it is actually something
– It would be admitting defeat to say that God created the universe out of nothing

3. Fine-Tuning:
– It could be the case that the fundamental constants are not variable
– It could be the case that the fine-tuning of the cosmic constants is a happy accident
– It could be the case that there are billions of billions of unobservable universes that are not fine tuned
– It could be the case that the cosmic constants in these billions and billions of unobservable universes are all random so that some are fine-tuned
– Anyone who infers that an intelligence is the best explanation of a finely-tuned set of life-permitting cosmic constants is lazy

4. Purpose:
– Philosophers and theologians are stupid
– I don’t think that there is purpose in the universe
– I think that the universe is more grand if there is no purpose, so there is no purpose

5. Miracles:
– I don’t think that miracles happen
– The resurrection is a fabrication
– It could be the case that Jesus didn’t exist
– It could be the case that Jesus wasn’t really crucified
– It could be the case that Jesus didn’t  really die after being crucified
– It could be the case that the disciples stole his body
– It could be the case that the women went to the wrong hole in the ground
– the gospels are political propaganda written long after the events they are reporting on

6. Theodicy:
– God has no morally sufficient reason for allowing humans to perform actions that result in suffering
– God has no morally sufficient reason for allowing nature to cause suffering

7. Morality:
–  customs and conventions emerges arbitrarily in different times and places based on an awareness of the consequences of actions, as well as various anecdotes and experiences
–  these customs and conventions are decided based on the goal for survival, in much the same way as politeness and manners emerge for decorum and to avoid offense
– it is childish to presume that there is an umpire God who decides moral values and duties

8. Religious believers are stupid, lazy and evil:
– the notion of God has arisen because people are stupid and want to be comforted
– there are no arguments or evidences for belief in God
– people who believe in God do not think, but instead take refuge in incomprehensible nonsense

Blake Giunta and Justin Schieber debate Christian theism vs naturalism

Here is the video of the debate:

And Blake’s summary of the debate from his TreeSearch.org web site.

In Justin’s opening statement, he made four arguments:

  1. The existence of rational unbelief is more consistent with naturalism
  2. Darwinian evolution is more consistent with naturalism
  3. The hostility to life in most of the universe is is more consistent with naturalism
  4. The existence of suffering among sentient beings is more consistent with naturalism

These are all good arguments for naturalism. That’s what atheists argue if they are willing to bear the burden of proof – those are quality arguments.

In Blake’s opening statement, he made three arguments:

  1. The existence of “the moral arena” is more consistent with theism
  2. The intelligibility and discoverability of the universe is more consistent with theism
  3. The historicity of the resurrection of Jesus is more consistent with theism

These arguments are also good arguments for theism and the last one is good for Christian theism. Again, quality arguments.

Here’s part of his summary of his first argument, which I think is different from anyone else:

The Moral Arena is very unexpected if Naturalism is true

By contrast, on naturalism, a Moral Arena could not be more unexpected.

Getting brains

(a) A Universe is entirely unexpected,
(b) and even if there were one, the naturalist has no reason to expect that the Universe would be life-permitting (because of our “fine-tuning of physics for life” discoveries),
(c) and even if it were life-permitting, the naturalist has no reason to expected that there would be an origin of life event in it.
(d) and even if one (or more happened), the naturalist has no reason to expect that it would culminate in the existence of brains or anything that functions like a brain.

The alleged problem with this is that, it means that the likelihood of brains existing, on naturalism, are unfathomably low. Blake noted that the improbabilities of (a)-(d) could be multiplied together, and the likelihood of this chain of events assuming the truth of naturalism was well below .0000000001, just for the fine-tuning problem alone.

From there, getting consciousness

But getting such brains is not enough to get a Moral Arena. The next improbability was the brains being conscious. Once again, this could not be more unexpected on naturalism. Blake argued that consciousness is not adaptive on naturalism, because the brain is basically the machine, and consciousness was like smoke–the machine would evolve and operate the same with or without the smoke. Moreover, as a naturalist looks at the object of a brain, nothing “in it” would lead him to expect it has conscious experience, any more than looking at a star or electron would. Finally, Blake noted that many of the most prestigious naturalists argue that consciousness is not only entirely unexpected, but actually incompatible with naturalism–it has to be an illusion.

From there, getting beliefs

Blake then said, “Ok, but lets say you do get conscious brains. What is the likelihood, on naturalism, that they would also have these very particular things called beliefs?” He made the same moves: it could not be more unexpected on naturalism, and moreover some of the most prominent naturalists argue that beliefs are incompatible with naturalism. The reason is because beliefs are “about” things, but material objects (like rocks and brains) can’t be “about” anything. So beliefs are non-physical, which naturalism cannot accommodate.

From there, getting moral beliefs (for a Moral Arena)

Finally, Blake noted one more requirement: “Ok, so lets say you evolve conscious brains with beliefs, what is the likelihood that they would have moral beliefs in particular.” There is no reason to think moral beliefs, beliefs about good and evil, or right and wrong, would ever evolve twice in the entire Universe. But then why anticipate that they would have evolved even once? Again, Naturalism has no such reason. In each of these cases, all I can do is helplessly look at what has occurred, and say “oh, interesting.”

All together now

Calculating the final improbability involves multiplying the unlikelihood of brains evolving (.0000000001) with the unlikelihood of evolved brains being conscious (e.g. .01), with the unlikelihood of evolved conscious brains having beliefs (e.g. 01) with the unlikelihood of such brains having moral beliefs in particular (e.g. .5). The final probability is extraordinarily low, and insofar as moral beliefs are required for a moral arena, the likelihood of a moral arena existing on naturalism is unfathomably low (e.g. it seems like on naturalism, the likelihood of a moral arena would be far less than  .000001%), while on theism it is not nearly so low (e.g. well over a 1% likelihood, and certainly no less). By definition then, the Moral Arena is evidence for theism, and it turns out to be phenomenally strong evidence given the difference in expectations. Originally, the plan was to give Justin a sheet of paper to fill these in, so we could talk specifically about any particularly unreasonable values he assigned to these probabilities.

If you are looking for a classy, civil debate, this is the debate you are looking for. Justin is a great speaker and presented four real arguments, but I think Blake had him beat on on substance, because Justin did not respond adequately to Blake’s arguments.

One point that came up in the debate was the distinction between coarse-tuning and fine-tuning, and whether the range of possible values for the numbers in question could be infinite. Allen Hainline saw the debate live, and he wrote this blog post on that topic.
