William Lane Craig debates Arif Ahmed: Does God Exist?

3 Comments

I thought that I would summarize a debate that occurred at Cambridge University between Dr. William Lane Craig and Dr. Arif Ahmed. Everyone knows Dr. Craig, but I should say that Arif Ahmed is a Senior Lecturer in the Faculty of Philosophy at Cambridge University.

The full MP3 is available here.

Below, I’ve summarized the two opening speeches from each debater. I put snarky clarifications in italics.

Here is Dr. Craig’s opening speech: (1:24)

Craig’s case for God.

1) The origin of the universe (3:10)
– an eternal universe is not compatible with mathematics
– the impossibility of an actual infinite in nature (cites David Hilbert)
– an eternal universe is not compatible with science
– the big bang theory requires space and time to come into being out of nothing (cites PCW Davies)
– even radical alternative theories require an absolute beginning (cites Stephen Hawking)
– atheists must believe that the origin of space and time came from nothing and by nothing (cites Anthony Kenny)

Argument:
P1.1) Whatever begins to exist requires a cause
P1.2) The universe begin to exist
C1.3) Therefore, the universe requires a cause

What can the cause be:
– it must be eternal, because it caused time to exist
– it must be non-physical, because it caused space to begin to exist

Why must the cause of the universe be a person instead of a force?
Only minds can exist non-physically
– the only non-physical entities we know of are abstract objects and minds
– but abstract objects can’t cause physical effects
– therefore, the cause universe is a personal mind

Only minds can cause effects in time without antecedent conditions
– causally prior to the universe’s beginning, there were no antecedent conditions
– the only entity capable of acting freely, not based on antecedent conditions, are free agents
– therefore, the cause of the universe is a free agent

2) The fine-tuning of the initial conditions of the universe (9:15)
– the fine-tuning of the universe is supported by science
– the constants and quantities given in the big bang can take any of a range of values
– the actual values are within a extremely narrow range that supports the requirements of life
– he gives the example of the fine-tuning of the gravitational constant
– he gives the example of the fine-tuning of the weak force

Argument:
P2.1) The fine-tuning is either due to law, chance or design
P2.2) It is not due to law, because the numbers are independent of the law
P2.3) It cannot be due to chance, the life-permitting band is tiny compared to the possible values
C2.4) Therefore, the fine-tuning is due to design

3) Objective moral values are plausibly grounded in God (12:41)
– objective moral values are values that exist and are binding regardless of what individuals think
– objective moral values cannot be rationally grounded on an atheistic worldview (cites Michael Ruse)
– atheists can recognize moral values and act on them, but they cannot explain their origin and existence
– atheists can only appeal to personal or cultural preferences to say what is right and wrong
– the existence of objective moral is undeniable

Argument:
P3.1) If God does not exist, then objective moral values do not exist
P3.2) Objective moral values do exist
C3.3) Therefore, God exists

4) The resurrection of Jesus implies that God exists (16:04)
– if the resurrection of Jesus happened, then it would be a miracle, implying that God exists
– three facts are recognized by the majority of scholars
– the tomb was found empty after his death (cites Jacob Kramer)
– individuals and groups saw Jesus after his death (cites Gerd Ludemann)
– the belief in the resurrection of Jesus was totally unexpected (cites N.T. Wright)
– naturalistic explanations of these facts have been rejected by the consensus of scholars

Argument:
P4.1) The 3 minimal facts are established
P4.2) The hypothesis that God raised Jesus from the dead is the best explanation for these facts
P4.3) The hypothesis that God raised Jesus from the dead entails that God exists
C4.4) Therefore, God exists

5) God can be known directly by personal experience (20:02)
– God can be experienced just like you experience a relationship with human persons

Dr. Ahmed’s first opening speech: (22:10)

Rebuttal to Craig’s case for God.

0) Craig is wrong about faith and reason (25:20)
– Craig’s book Reasonable Faith, he makes a number of statements about faith and reason
– He writes that Christianity is not accountable to reason if reason goes against Christianity
– He writes that the truth of Christianity is knowable without rational arguments
– He writes that even if there are no reasons to believe, and many reasons to disbelieve, humans are still obligated to believe
– Question for Craig: is Christianity reasonable or isn’t it? Do reasons matter or don’t they?

1) Response to Craig’s first argument: the origin of the universe (28:27)
– what mathematicians say about the contradictory nature of subtraction and division for actual infinities is wrong
– what cosmologists and physicists say about the beginning of time is wrong, every event follows another one, there is no first event
– even if the universe is 15 billion years old, the act of Creation requires time and there was no time prior to the supposed beginning of the universe for God to act in
– the cause of the universe need not be a personal agent
– all minds are made of matter so a mind cannot be the cause of the universe, 
– it is impossible for a person to act outside of time
– why did God wait 15 billion years before creating humans and relating to them? 

2) Response to Craig’s second argument: the fine-tuning of the creation (32:38)
– where do these probabilities that Craig is using come from?

3) Response to Craig’s third argument: the moral argument (34:07)
– I have personal preferences about what counts as right and wrong, and they are superior to God’s preferences
– moral intuitions are not a good way of discovering objective moral values, so therefore objective moral values don’t exist

4) Response to Craig’s fourth argument: the resurrection (36:00)
– the number of eyewitnesses is not enough, because groups number of eyewitnesses can be fooled by illusions, as in David Copperfield illusions
– the Gospels contradict themselves, e.g. – the story of Matthew’s earthquake and walking dead isn’t in Mark – so that’s a contradiction, so the Gospels are not reliable sources for Craig’s 3 minimal facts

5) Response to Craig’s fourth argument: personal experience (37:30)
– there are many different religious experiences because there are many different religions, which means that no one religion can be right

Ahmed’s case against God.

1) Absence of evidence is evidence of absence (39:00)
– if there is are no reasons to believe in God, then this is evidence that he doesn’t exist

2) The inductive argument from evil (40:04)
– some evil is gratuitous – events cause people to suffer, and has no benefit that I can see, which argues against the existence of a good God
– God would not have allowed people to suffer, because he has no overriding purpose that would justify his permission of human suffering

3) Belief in God makes people evil (41:52)
– all genuinely religious people are very immoral, when measured against my subjective standard of morality

Further study

In case you are wondering about his inductive argument from evil, please read this summary on the problems of evil and suffering, which is taken from my list of arguments for and against Christian theism.  Keep in my mind that I am a software engineer with two degrees in computer science… not philosophy!

Craig mentions a paper by the late William P. Alston of Syracuse University in his rebuttal to the inductive problem of evil. The paper lists six limitations on human cognitive capacities that make it difficult for humans to know that some instance of  apparently gratuitous evil really is gratuitious – that God has no morally sufficient reason for permitting this specific instance of evil.  Since Ahmed is making the claim that some evil is gratuitous, he bears the burden of proof.

Polemics

Did the divinity of Jesus emerge slowly after many years of embellishments?

7 Comments

How early is the doctrine of the divinity of Jesus?

When I answer this question, I only want to use the earliest, most reliable sources – so I can defend them on historical grounds using the standard rules of historiography.

The 4 sources that I would use are as follows:

  • The early creed in 1 Corinthians 15:3-8, and 1 Corinthians 1
  • A passage in Philippians 2
  • Two passages from Mark, the earliest gospel
  • A passage from Q, which is an early source of Matthew and Luke

So let’s see the passages.

1 Corinthians

I’ve written before about the early creed in 1 Corinthians 15:3-8, which skeptical scholars date to 1-3 years after the death of Jesus, for a variety of reasons I covered in the previous post. Here’s the creed which definitely makes Jesus out to be more than an ordinary man. Ordinary men don’t get resurrection bodies after they die.

Here’s the passage: (1 Cor 15:3-8)

3For what I received I passed on to you as of first importance: that Christ died for our sins according to the Scriptures,

4that he was buried, that he was raised on the third day according to the Scriptures,

5and that he appeared to Peter, and then to the Twelve.

6After that, he appeared to more than five hundred of the brothers at the same time, most of whom are still living, though some have fallen asleep.

7Then he appeared to James, then to all the apostles,

8and last of all he appeared to me also, as to one abnormally born.

Additionally, 1 Corinthians 1:21-25 talks about Jesus being “the power of God and the wisdom of God”. Paul is identifying Jesus with the divine.

21For since in the wisdom of God the world through its wisdom did not know him, God was pleased through the foolishness of what was preached to save those who believe.

22Jews demand miraculous signs and Greeks look for wisdom,

23but we preach Christ crucified: a stumbling block to Jews and foolishness to Gentiles,

24but to those whom God has called, both Jews and Greeks, Christ the power of God and the wisdom of God.

25For the foolishness of God is wiser than man’s wisdom, and the weakness of God is stronger than man’s strength.

But it gets even stronger! You all probably already know that the most important passages in the Old Testament for Jews is the famous “Shema“, which is found in Deuteronomy 6:4-9. The Shema is a strong statement of Jewish monotheism.

Here’s the passage:

4 Hear, O Israel: The LORD our God, the LORD is one.

5 Love the LORD your God with all your heart and with all your soul and with all your strength.

6 These commandments that I give you today are to be upon your hearts.

7 Impress them on your children. Talk about them when you sit at home and when you walk along the road, when you lie down and when you get up.

8 Tie them as symbols on your hands and bind them on your foreheads.

9 Write them on the doorframes of your houses and on your gates.

So how does Paul fit Jesus in with this strong statement of Jewish monotheism?

Paul alludes to the Shema in 1 Corinthians 8:4-6.

4So then, about eating food sacrificed to idols: We know that an idol is nothing at all in the world and that there is no God but one.

5For even if there are so-called gods, whether in heaven or on earth (as indeed there are many “gods” and many “lords”),

6yet for us there is but one God, the Father, from whom all things came and for whom we live; and there is but one Lord, Jesus Christ, through whom all things came and through whom we live.

Holy mackerel! How did that get in there? Paul is splitting the roles of God in the the Shema and identifying Jesus in one of the divine roles! Jesus is not an ordinary man. That passage “through whom all things came” foreshadows John identifying Jesus as “the Word of God”, which “became flesh and dwelt among us”. Holy snark – did you guys know that was all in here so early?

The date for 1 Corinthians is 55 AD. It should be noted that skeptical scholars like James Crossley accept these passages, and you can check it out in the debate audio yourself.

Philippians

Check out Philippians 2:5-11.

5Your attitude should be the same as that of Christ Jesus:

6Who, being in very nature God, did not consider equality with God something to be grasped,

7but made himself nothing, taking the very nature of a servant, being made in human likeness.

8And being found in appearance as a man, he humbled himself and became obedient to death— even death on a cross!

9Therefore God exalted him to the highest place and gave him the name that is above every name,

10that at the name of Jesus every knee should bow, in heaven and on earth and under the earth,

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

The date for Philippians is 60-61 AD. Still within the lifetime of the eyewitnesses, and written by an eyewitness who was in contact with the other eyewitnesses, like Peter and James, whom Paul spoke with numerous times on his journeys to Jerusalem.

Mark’s gospel

Mark’s gospel is the earliest and atheists like James Crossley date it to less than 40 AD, which is 10 years after the death of Jesus at most. When you read the gospel of Mark, you are getting the earliest and best information available about the historical Jesus, along with Paul’s epistles. So what does Mark say about Jesus? Is Jesus just a man, or is he something more?

Check out Mark 12:1-9:

1He then began to speak to them in parables: “A man planted a vineyard. He put a wall around it, dug a pit for the winepress and built a watchtower. Then he rented the vineyard to some farmers and went away on a journey.

2At harvest time he sent a servant to the tenants to collect from them some of the fruit of the vineyard.

3But they seized him, beat him and sent him away empty-handed.

4Then he sent another servant to them; they struck this man on the head and treated him shamefully.

5He sent still another, and that one they killed. He sent many others; some of them they beat, others they killed.

6“He had one left to send, a son, whom he loved. He sent him last of all, saying, ‘They will respect my son.’

7“But the tenants said to one another, ‘This is the heir. Come, let’s kill him, and the inheritance will be ours.’

8So they took him and killed him, and threw him out of the vineyard.

9“What then will the owner of the vineyard do? He will come and kill those tenants and give the vineyard to others.

And Mark 13:32, talking about the date of the final judgment.

32“No one knows about that day or hour, not even the angels in heaven, nor the Son, but only the Father.

And again, this passage is establishing a hierarchy such that Jesus is being exalted above all men and the angels, too. And the passage is embarrassing to the early church, because it makes Jesus look ignorant of something, so they would not have made this passage up. Jesus is not an ordinary man, he is above the angels – God’s unique Son.

The “Q” source for Matthew and Luke

Here’s Matthew 11:27, which is echoed in Luke 10:22:

27“All things have been committed to me by my Father. No one knows the Son except the Father, and no one knows the Father except the Son and those to whom the Son chooses to reveal him.

22“All things have been committed to me by my Father. No one knows who the Son is except the Father, and no one knows who the Father is except the Son and those to whom the Son chooses to reveal him.”

Since this passage is in both of Matthew and Luke, but not in Mark, scholars believe that it is in the earlier “Q” source used by both Matthew and Luke. Q predates both Matthew and Luke, and so it is also fairly early (maybe 67-68), although not as early as Mark and Paul. Bill Craig writes that this passage is also embarrassing because it says that no one knows Jesus.

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

Leave a comment

If you missed last night’s lecture that was live-streamed from the University of Calgary, you can watch this one, which was on the same topic.

Note: even if you have heard Dr. Craig’s arguments before, I recommend jumping to the 48 minutes of 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.
