There is a very famous thought experiment from UC Berkeley philosopher John Searle that all Christian apologists should know about. And now everyone who reads the Wall Street Journal knows about it, because of this article.
In that article, Searle is writing about the IBM computer that was programmed to play Jeopardy. Can a robot who wins on Jeopardy be “human”? Searle says no. And his famous Chinese room example (discussed in the article) explains why.
Imagine that a person—me, for example—knows no Chinese and is locked in a room with boxes full of Chinese symbols and an instruction book written in English for manipulating the symbols. Unknown to me, the boxes are called “the database” and the instruction book is called “the program.” I am called “the computer.”
People outside the room pass in bunches of Chinese symbols that, unknown to me, are questions. I look up in the instruction book what I am supposed to do and I give back answers in Chinese symbols.
Suppose I get so good at shuffling the symbols and passing out the answers that my answers are indistinguishable from a native Chinese speaker’s. I give every indication of understanding the language despite the fact that I actually don’t understand a word of Chinese.
And if I do not, neither does any digital computer, because no computer, qua computer, has anything I do not have. It has stocks of symbols, rules for manipulating symbols, a system that allows it to rapidly transition from zeros to ones, and the ability to process inputs and outputs. That is it. There is nothing else.
Here is a link to the full article by John Searle on the Chinese room illustration.
By the way, Searle is a naturalist – not a theist, not a Christian. Now, let’s hear from a Christian scholar who can make more sense of this for us.
Popular discussions of AI often suggest that if you keep increasing weak AI, at some point, you’ll get strong AI. That is, if you get enough computation, you’ll eventually get consciousness.
The reasoning goes something like this: There will be a moment at which a computer will be indistinguishable from a human intelligent agent in a blind test. At that point, we will have intelligent, conscious machines.
This does not follow. A computer may pass the Turing test, but that doesn’t mean that it will actually be a self-conscious, free agent.
The point seems obvious, but we can easily be beguiled by the way we speak of computers: We talk about computers learning, making mistakes, becoming more intelligent, and so forth. We need to remember that we are speaking metaphorically.
We can also be led astray by unexamined metaphysical assumptions. If we’re just computers made of meat, and we happened to become conscious at some point, what’s to stop computers from doing the same? That makes sense if you accept the premise—as many AI researchers do. If you don’t accept the premise, though, you don’t have to accept the conclusion.
In fact, there’s no good reason to assume that consciousness and agency emerge by accident at some threshold of speed and computational power in computers. We know by introspection that we are conscious, free beings—though we really don’t know how this works. So we naturally attribute consciousness to other humans. We also know generally what’s going on inside a computer, since we build them, and it has nothing to do with consciousness. It’s quite likely that consciousness is qualitatively different from the type of computation that we have developed in computers (as the “Chinese Room” argument, by philosopher John Searle, seems to show). Remember that, and you’ll suffer less anxiety as computers become more powerful.
Even if computer technology provides accelerating returns for the foreseeable future, it doesn’t follow that we’ll be replacing ourselves anytime soon. AI enthusiasts often make highly simplistic assumptions about human nature and biology. Rather than marveling at the ways in which computation illuminates our understanding of the microscopic biological world, many treat biological systems as nothing but clunky, soon-to-be-obsolete conglomerations of hardware and software. Fanciful speculations about uploading ourselves onto the Internet and transcending our biology rest on these simplistic assumptions. This is a common philosophical blind spot in the AI community, but it’s not a danger of AI research itself, which primarily involves programming and computers.
AI researchers often mix topics from different disciplines—biology, physics, computer science, robotics—and this causes critics to do the same. For instance, many critics worry that AI research leads inevitably to tampering with human nature. But different types of research raise different concerns. There are serious ethical questions when we’re dealing with human cloning and research that destroys human embryos. But AI research in itself does not raise these concerns. It normally involves computers, machines, and programming. While all technology raises ethical issues, we should be less worried about AI research—which has many benign applications—than research that treats human life as a means rather than an end.
When I am playing a game on the computer, I know exactly why what I am doing is fun – I am conscious of it. But the computer has no idea what I am doing. It is just matter in motion, acting on it’s programming and the inputs I supply to it. And that’s all computers will ever do. Trust me, this is my field. I have the BS and MS in computer science, and I have studied this area. AI has applications for machine learning and search problems, but consciousness is not on the radar. You can’t get there from here.
Bart Ehrman is well known as a US New Testament Scholar who lost his Christian faith and now questions many core precepts of Christianity, including the Resurrection of Jesus. When Mike Licona had doubts he devoted himself to investigating the evidence and became convinced that Jesus resurrection is the only rational explanation for the facts.
They debate key historical facts about the resurrection – are the letters of Paul that report the resurrection and the Gospel accounts trustworthy or theologised and changed with time? What about apparent contradictions between the Gospels? Does the consensus of scholars count as evidence, or is there a Christian bias? Can a miracle count as an explanation for historical data?
Snarky summary of the radio debate: (items with * are my made-up paraphrases/clarifications)
This has got to be one of my silliest summaries, but Ehrman makes me so annoyed.
– my new book is about forgeries in the ancient world
– some books were falsely attributed to prominent Christian figures
– there are mistakes in the Bible
– there are mistakes in the resurrection narratives
– the defeat of inerrancy led to his conversion to liberal Christianity
– the problem of evil and suffering caused him to become a non-Christian
– there are minimal facts that are agreed to by a broad spectrum of scholars
– the minimal facts are accepted because they pass standard historical criteria
– Fact 1: Jesus died by crucifixion
– Fact 2: Individuals and groups had visions of Jesus after his death
– Fact 3: Paul, a skeptic and an enemy, had an appearance of Jesus that converted him
– these facts are agreed to atheist scholars, liberal scholars, etc.
– virtually 100% of scholars agree with these three facts
– there is no naturalistic explanation of these three facts
– therefore, the best explanation of these three facts is that God raised Jesus from the dead
– all historians would accept these three facts, except for maybe the group appearances
– the death of Jesus is irrelevant to the resurrection
– the second and third point can be collapsed together
– so really there is only one fact
– the crucifixion is relevant because Muslims don’t admit that fact
– the crucifixion important because it establishes a resurrection, not a resuscitation
– well, if the point is that he died, then yes, this does require a resurrection
– the crucifixion refutes Muslims who deny that Jesus died
– the crucifixion refutes the apparent death theory (swoon theory)
– the death is required for a bodily resurrection
– it’s important to know what facts most scholars, regardless of worldview, agree on
– it’s important to emphasize that Licona is working from historical bedrock facts
– the resurrection is the best explanation for the historical bedrock facts
– you are trying to list 3 things, but really it is just one thing – the appearances
– and not ALL scholars agree that the group visions occurred
– name one prominent scholar who denies the group appearances
– the radically leftist atheist nutcase John Dominic Crossan denies the group appearances
* Crossan is so far on the left that I look like a nutcase for even citing him
* Crossan believes in the Secret Gospel of Mark, which is a hoax – but I still cite Crossan
* Crossan believes that the synoptics are LATER than gnostic forged gospels – but I still cite Crossan
* Crossan presupposes atheism, so he cannot admit to miracle stories as a pre-supposition – but I still cite Crossan
* Crossan pre-supposes religious pluralism, so he cannot allow any exclusive claims Christians make – but I still cite Crossan
* Crossan is a good historian, it’s just that he is so far to the left that no one – NO ONE – agrees with his all of crazy theories
* I think it is a good idea to cite historians who pre-suppose atheism and political correctness before they sit down to do history
– let me explain why most scholars accept the individual and group post-mortem appearances
– the best source for the appearances is the early creed recorded by Paul in 1 Cor 15:3-8
– Paul himself had an appearance of Jesus after Jesus’ death
– Paul received this material from a source very soon after the appearances – within 1-3 years
– we know that Paul met with Jesus disciples multiple times prior to writing
– Paul probably received it from Peter and James, who were themselves eyewitnesses
– this early dating presumably rules out legend
– well legends CAN start quickly
– it does show that Paul was an eyewitness
– it does show that Paul was in contact with reliable eyewitnesses
– 1 Corinthians is written around 55 AD, twenty-five years after Jesus died
– it is not implausible that Paul got the creed from the disciples, who were eyewitnesses
– but you don’t need a long time for legends to emerge, so that is a possibility
– only about 3% of people could read and write back them
– instead, people had enormous capacity for memorization
– the Pharisees were particularly good at memorization
– Jews were very serious about passing along traditions accurately
– Paul, a prominent Pharisee, would have been capable of passing on early creeds accurately
– Paul, in 1 Cor 7, shows that he is willing to separate his opinions from authentic tradition
– Paul had an opportunity in 1 Cor 7 to put words into Jesus’ mouth, but he wouldn’t do it
– cultural anthropologists show that things do get changed in some oral cultures
– in these oral cultures, it is assumed that the story teller will change the story
– only in written cultures are they careful to avoid changing the story
– in the New Testament, you can compare the same story in two different gospels, there are differences
– Ehrman is right that the gospel writers pick and choose things from the oral tradition that they want to include in their gospels
– different oral tradition transmission schemes have more or less embellishment
– african tribes embellish more, rabbinic teaching embellishes less
* Jesus’ followers would have viewed him as a rabbi, and been careful about adding to his teachings
– Paul, an eyewitness, probably received the creed in 1 Cor 15 from other eyewitnesses
– Paul speaks about going twice to Jerusalem in Galatians
– he is meeting with Peter and James to check his facts
– when you look at Mark and John, there are lots of differences in the narrative
– I agree that the gospels have differences, but the oral tradition is likely fixed
– but Mark and John have different sayings
– why doesn’t Mark have the same explicit high Christology that John has?
– the “apocalyptic Son of Man” isn’t in John
– what about in John 9 with the man who was born blind
– where is the apocalyptic part?
– the healed man worships Jesus because he is the Son of Man
– that links to the apocalypic passages in the Old Testament
– what about the differences between the gospels?
* well, now is the time for me to set up an inerrantist straw man and then knock it down!
* who was at the empty tomb: one angel or two angels? we don’t know, so the whole Bible is false!
* I used to be an inerrantist, so one minor difference is enough for me to dump the whole Bible
* I’ll kill you, you stupid straw man! I hate you, Moody Bible Institute! You lied to me!
– many of these problems can be solved by realizing that the gospel writers compress time
– the stories don’t have to list ALL the characters in every scene
– you don’t have to force the Bible to meet some sort of wooden chronology
– the main thing is that the events happened, not that the descriptions match word for word across sources
– you can’t infer a miracle from history, David Hume says so
* extraordinary claims require extraordinary evidence, David Hume says so
* no I don’t know what begging the question is, I’m not a philosopher
* no I don’t remember when Bill Craig kicked my ass on this Hume objection in our debate
– the New Testament gospels contradict each other at every point, they are not reliable at all!
* they cannot even agree what Jesus’ name is! There are 1 trillion variants of Jesus’ name!
* “one angel vs two angels” proves that the gospels contradict each other at every point
* my expansive list of FOUR theologically insignificant variants proves that the gospels contradict each other at every point
– um, the gospels agree on the central narrative and disagree on the peripherals
– and they agree on the minimal facts I presented, even if they disagree about the number of angels
* they have to agree on everything and be inerrant! The Moody Straw Man Bible Institute says so!
* I really really really need to have the number of angels be the same, or Jesus didn’t die on the cross
– but you don’t deny any of the three minimal facts I presented (crucifixion, appearances, Paul)
– well, I don’t know if the group appearances occurred – maybe they did
– i think Jesus died on the cross, and I think that people said they saw him alive afterward
– if you deny the minimal facts, then you are outside the majority of scholars
– the majority of scholars who agree to the minimal facts you presented are Christians
* Gerd Ludemann is an atheist Christian
* James Crossley is an atheist Christian
* Hector Avalos is an atheist Christian
* the majority of the atheist scholars are all Christians!
– VIRTUALLY EVERYBODY IN THE SOCIETY OF BIBLICAL LITERATURE IS A CHRISTIAN!!! (Yes, he said that)
– but he CLAIMS TO BE A CHRISTIAN so that means HE IS A CHRISTIAN
* all you have to do to be a Christian is claim to be one
* you can even deny the existence of God and the divinity of Christ and still be one, you bigot!
– would Jesus or the apostles recognize a Christian as being someone who doubts God’s existence
– my view is that Jesus and the apostles would not recognize evangelical Christians as Christians
* a non-theist can be a Christian just by claiming to be one, but evangelical Christians are not Christians even if they claim to be Christians
– Christians can’t record accurate history about the resurrection because they are biased
– on your view, if a person is a Christian then he can’t write about the evidence for the resurrection
– so then similarly, you would not allow Jews to write about the historicity of the Holocaust
– because you think that if people have an interest in what they are recording then they can’t be objective
– but you have to consider the evidence we have, taking the biases of the sources into account
– but the only people who believe in the resurrection are Christians!
– well, people can consider the evidence for the resurrection as non-Christians
– and then if they accept it they can become Christians
– what about your bias? you don’t believe in God – doesn’t that pre-supposition affect how you do history?
– well, I presuppose naturalism, so I can’t admit to anything in history that implicates supernatural causes
* no I have never heard of the arguments for the Big Bang, fine-tuning, origin of life, Cambrian explosion, irreducible complexity, limits on mutations creating information, habitability and so on – I never heard about that stuff from my atheist university professors and even if I had I would have been expelled for talking about it because that would make people feel bad about their sinning
– so it’s not bias you are concerned about, it’s that you don’t want history to contradict your untested religion of naturalism?
– why not just do the history without pre-suppositions to gather the minimal facts and then see what the best explanation is?
* well God is out of bounds as an explanation because I could not have got my PhD if I mentioned God
* I really needed my smart atheist professors to like me and give me good grades so God is RIGHT OUT
* ideas like a real God and moral laws and Hell makes my atheist professors uncomfortable and that means low grades for me
* I’m not really interested in butting heads with professors – it’s easier to just agree with them and move on to selling books to the gullible
* My books are much more sensational than Dan Brown books, so please buy lots of them!
– what if the historical evidence is good enough to show that Jesus rose from the dead?
– well I would not call someone rising from the dead a miracle – I would call it weird
* I also think that the Big Bang is “weird” but that doesn’t prove that God created the universe out of nothing
* if it’s a miracle then I’m going to have to not sin, and maybe even go to Hell, and we can’t have that
– well, you accept the three minimal facts
– what if we try all the naturalistic explanations for those three facts and there are problems with all of them?
– what if the resurrection is the best explanation for the three minimal facts?
– but I want to arbitrarily rule God put because I want to pre-suppose naturalism
– there is not historical reason I have to rule put supernatural explanations a priori
– I think you are struggling with the theological implications of a historical conclusion
– well when you do theology, you have to avoid grounding your theology on science or history
– theology has to be completely made up or it’s not good theology
– I think you are letting your dislike of the implications of the resurrection determine your historical conclusions
– you have to use historical methods to gather the minimal facts that every scholar accepts, regardless of worldview
– then you weigh ALL the hypotheses, natural and supernatural, that could account for these minimal facts
– then you choose the hypothesis that best explains the minimal facts
1. Prior to Christ’s ascension, all who died descended to Sheol/Hades, which was divided into two parts, one for the wicked and one for the righteous.
2. At Christ’s ascension, he went into heaven and took with him all of the saints in the paradisal part of Sheol/Hades, while the wicked remain in Sheol/Hades, waiting for judgment.
3. Upon death new covenant believers go to be with Christ in heaven ahead of the general resurrection, while the wicked descend to Sheol/Hades waiting for judgment.
4. Eventually Sheol/Hades will be thrown into hell and all believers will share in the new heavens and new earth.
See Evangelical Theology p. 323.
I’ve featured some debates with Michael Bird before, he is a famous evangelical historian.
It’s important to understand that the Christian view of humans is that we have a material part and a non-material part. When you die, the material part goes into a tomb. The non-material part goes on to be with God, until the day when you get a new resurrection body.
Here’s a lecture from N.T. Wright, whose multi-volume case for the historicity of the bodily resurrection of Jesus seems to be getting a lot of respect from the other side, (although I strongly disagree with his economic and political views, which are naive at best). Wright has taught at Cambridge University, Oxford University, Duke University, McGill University, and lectured on dozens of prestigious campuses around the world. He’s published 40 books.
Here’s a video of his case for the resurrection:
N.T. Wright’s historical case for the bodily resurrection of Jesus
Wright basically argues that the resurrection cannot have been a myth invented by the early Christian community, because the idea of the Messiah dying and being bodily resurrected to eternal life was completely unexpected in Jewish theology, and therefore would not have been fabricated.
In Judaism, when people die, they stay dead. At the most, they might re-appear as apparitions, or be resuscitated to life for a while, but then die again later. There was no concept of the bodily resurrection to eternal life of a single person, especially of the Messiah, prior to the general resurrection of all the righteous dead on judgment day.
Wright’s case for the resurrection has 3 parts:
The Jewish theological beliefs of the early Christian community underwent 7 mutations that are inexplicable apart from the bodily resurrection of Jesus
The empty tomb
The post-mortem appearances of Jesus to individuals and groups, friends and foes
Here’s the outline of Wright’s case:
…the foundation of my argument for what happened at Easter is the reflection that this Jewish hope has undergone remarkable modifications or mutations within early Christianity, which can be plotted consistently right across the first two centuries. And these mutations are so striking, in an area of human experience where societies tend to be very conservative, that they force the historian… to ask, Why did they occur?
The mutations occur within a strictly Jewish context. The early Christians held firmly, like most of their Jewish contemporaries, to a two-step belief about the future: first, death and whatever lies immediately beyond; second, a new bodily existence in a newly remade world. ‘Resurrection’ is not a fancy word for ‘life after death’; it denotes life after ‘life after death’.
And here are the 7 mutations:
Christian theology of the afterlife mutates from multiples views (Judaism) to a single view: resurrection (Christianity). When you die, your soul goes off to wait in Sheol. On judgment day, the righteous dead get new resurrection bodies, identical to Jesus’ resurrection body.
The relative importance of the doctrine of resurrection changes from being peripheral (Judaism) to central (Christianity).
The idea of what the resurrection would be like goes from multiple views (Judaism) to a single view: an incorruptible, spiritually-oriented body composed of the material of the previous corruptible body (Christianity).
The timing of the resurrection changes from judgment day (Judaism) to a split between the resurrection of the Messiah right now and the resurrection of the rest of the righteous on judgment day (Christianity).
There is a new view of eschatology as collaboration with God to transform the world.
There is a new metaphorical concept of resurrection, referred to as being “born-again”.
There is a new association of the concept of resurrection to the Messiah. (The Messiah was not even supposed to die, and he certainly wasn’t supposed to rise again from the dead in a resurrected body!)
There are also other historical puzzles that are solved by postulating a bodily resurrection of Jesus.
Jewish people thought that the Messiah was not supposed to die. Although there were lots of (warrior) Messiahs running around at the time, whenever they got killed, their followers would abandon them. Why didn’t Jesus’ followers abandon him when he died?
If the early Christian church wanted to communicate that Jesus was special, despite his shameful death on the cross, they would have made up a story using the existing Jewish concept of exaltation. Applying the concept of bodily resurrection to a dead Messiah would be a radical departure from Jewish theology, when an invented exaltation was already available to do the job.
The early church became extremely reckless about sickness and death, taking care of people with communicable diseases and testifying about their faith in the face of torture and execution. Why did they scorn sickness and death?
The gospels, especially Mark, do not contain any embellishments and “theology historicized”. If they were made-up, there would have been events that had some connection to theological concepts. But the narratives are instead bare-bones: “Guy dies public death. People encounter same guy alive later.” Plain vanilla narrative.
The story of the women who were the first witnesses to the empty tomb cannot have been invented, because the testimony of women was inadmissible under almost all circumstances at that time. If the story were invented, they would have invented male discoverers of the tomb. Female discovers would have hampered conversion efforts.
There are almost no legendary embellishments in the gospels, while there are plenty in the later gnostic forgeries. No crowds of singing angels, no talking crosses, and no booming voices from the clouds.
There is no mention of the future hope of the general resurrection, which I guess they thought was imminent anyway.
To conclude, Wright makes the argument that the best explanation of all of these changes in theology and practice is that God raised Jesus (bodily) from the dead. There is simply no way that this community would have made up the single resurrection of the Messiah – who wasn’t even supposed to die – and then put themselves on the line for that belief.
And remember, the belief in a resurrected Jesus was something that the earliest witnesses could really assess, because they were the ones who saw him killed and then walking around again after his death. They were able to confirm or deny their belief in the resurrection of Jesus based on their own personal experiences with the object of those beliefs.
This podcast is a must-listen. Please take the time to download this podcast and listen to it. I guarantee that you will love this podcast. I even recommended it to my Dad and I almost never do that.
In this podcast, J. Warner examines the evidence for the existence of the mind (and inferentially, the soul) as he looks at six classic philosophical arguments. Jim also briefly discusses Thomas Nagel’s book, Mind and Cosmos and discusses the limitations of physicalism.
Even though the theistic outlook, in some versions, is consistent with the available scientific evidence, I don’t believe it, and am drawn instead to a naturalistic, though non-materialist, alternative. Mind, I suspect, is not an inexplicable accident or a divine and anomalous gift but a basic aspect of nature that we will not understand until we transcend the built-in limits of contemporary scientific orthodoxy.
When looking at this question, it’s important to not have our conclusions pre-determined by presupposing materialism or atheism
If your mind/soul doesn’t exist and you are a purely physical being then that is a defeater for Christianity, so we need to respond
Traditionally, Christians have been committed to a view of human nature called “dualism” – human beings are souls who have bodies
The best way* to argue for the existence of the soul is using philosophical arguments
The law of identity says that if A = B’ if A and B have the exact same properties
If A = the mind and B = the brain, then is A identical to B?
Wallace will present 6 arguments to show that A is not identical to B because they have different properties
Not everyone of the arguments below might make sense to you, but you will probably find one or two that strike you as correct. Some of the points are more illustrative than persuasive, like #2. However, I do find #3, #5 and #6 persuasive.
1) First-person access to mental properties
Thought experiment: Imagine your dream car, and picture it clearly in your mind
If we invited an artist to come and sketch out your dream car, then we could see your dream car’s shape on paper
This concept of your dream car is not something that people can see by looking at your brain structure
Physical properties can be physically accessed, but the properties of your dream care and privately accessed
2) Our experience of consciousness implies that we are not our bodies
Common sense notion of personhood is that we own our bodies, but we are not our bodies
3) Persistent self-identity through time
Thought experiment: replacing a new car with an old car one piece at a time
When you change even the smallest part of a physical object, it changes the identity of that object
Similarly, your body is undergoing changes constantly over time
Every cell in your body is different from the body you had 10 years ago
Even your brain cells undergo changes (see this from New Scientist – WK)
If you are the same person you were 10 years ago, then you are not your physical body
4) Mental properties cannot be measured like physical objects
Physical objects can be measured (e.g. – use physical measurements to measure weight, size, etc.)
Mental properties cannot be measured
5) Intentionality or About-ness
Mental entities can refer to realities that are physical, something outside of themselves
A tree is not about anything, it just is a physical object
But you can have thoughts about the tree out there in the garden that needs water
6) Free will and personal responsibility
If humans are purely physical, then all our actions are determined by sensory inputs and genetic programming
Biological determinism is not compatible with free will, and free will is required for personal responsibility
Our experience of moral choices and moral responsibility requires free will, and free will requires minds/souls
He spends the last 10 minutes of the podcast responding to naturalistic objections to the mind/soul hypothesis.
*Now in the podcast, Wallace does say that scientific evidence is not the best kind of evidence to use when discussing this issue of body/soul and mind/brain. But I did blog before about two pieces of evidence that I think are relevant to this discussion: corroborated near-death experiences and mental effort.
You might remember that Dr. Craig brought up the issue of substance dualism, and the argument from intentionality (“aboutness”), in his debate with the naturalist philosopher Alex Rosenberg, so this argument about dualism is battle-ready. You can add it to your list of arguments for Christian theism along with all the other arguments like the Big Bang, the fine-tuning, the origin of life, stellar habitability, galactic habitability, irreducible complexity, molecular machines, the Cambrian explosion, the moral argument, the resurrection, biological convergence, and so on.
