William Lane Craig debates Austin Dacey: Does God Exist?

2 Comments

Here is the video and summary of a debate between Christian theist William Lane Craig and Austin Dacey at Purdue University in 2004 about the existence of God.

The debaters:

The video: (2 hours)

The video shows the speakers and powerpoint slides of their arguments. Austin Dacey is one of the top atheist debaters, and I would put him second to Peter Millican alone, with Walter Sinnott-Armstrong in third place. This is the debate to show people who are new to apologetics. The debate with Peter Millican is better for advanced students, and that’s no surprise since he teaches at Oxford University and is familiar with all of Dr. Craig’s work. The Craig-Dacey debate is the one that I give to my co-workers.

By the way, you can get the DVDs and CDs for the first Craig-Dacey debate and the second Craig-Dacey debate and the second Craig-Sinnott-Armstrong debate. The Peter Millican debate is not available on DVD, but the link above (Peter Millican) has the video and my summary.

Dr. Dacey’s 5 arguments below are all good arguments that you find in the academic literature. He is also an effective and engaging speaker, This is a great debate to watch!

SUMMARY of the opening speeches:

Dr. Craig’s opening statement:

Dr. Craig will present six reasons why God exists:

  1. (Contingency argument) God is the best explanation of why something exists rather than nothing
  2. (Cosmological argument)  God’s existence is implied by the origin of the universe
  3. (Fine-tuning argument) The fine-tuning of the universe for intelligent life points to a designer of the cosmos
  4. (Moral argument) God is the best explanation for the existence of objective moral values and objective moral duties
  5. (Miracles argument) The historical facts surrounding the life, death and resurrection of Jesus
  6. (Religious experience) God’s existence is directly knowable even apart from arguments

Dr. Dacey’s opening argument:

There are two ways to disprove God’s existence, by showing that the concept of God is self-contradictory, or by showing that certain facts about ourselves and the world are incompatible with what we would expect to be true if God did exist. Dr. Dacey will focus on the second kind of argument.

  1. The hiddenness of God
  2. The success of science in explaining nature without needing a supernatural agency
  3. The dependence of mind on physical processes in the brain
  4. Naturalistic evolution
  5. The existence of gratuitous / pointless evil and suffering

One final point:

One thing that I have to point out is that Dr. Dacey quotes Brian Greene during the debate to counter Dr. Craig’s cosmological argument. Dr. Craig could not respond because he can’t see the context of the quote. However, Dr. Craig had a rematch with Dr. Dacey where was able to read the context of the quote and defuse Dr. Dacey’s objection. This is what he wrote in his August 2005 newsletter after the re-match:

The following week, I was off an another three-day trip, this time to California State University at Fresno. As part of a week of campus outreach the Veritas Forum scheduled a debate on the existence of God between me and Austin Dacey, whom I had debated last spring at Purdue University. In preparation for the rematch I adopted two strategies: (1) Since Dacey had come to the Purdue debate with prepared speeches, I decided to throw him for a loop by offering a different set of arguments for God, so that his canned objections wouldn’t apply. I chose to focus on the cosmological argument, giving four separate arguments for the beginning of the universe, and on the evidence for Jesus’ resurrection. (2) I reviewed our previous debate carefully, preparing critiques of his five atheistic arguments. In the process I found that he had seriously misunderstood or misrepresented a statement by a scientist on the Big Bang; so I brought along the book itself in case Dacey quoted this source again. I figured he might change his arguments just as I was doing; but I wanted to be ready in case he used his old arguments again.

[…]The auditorium was packed that night for the debate, and I later learned that there were overflow rooms, too. To my surprise Dr. Dacey gave the very same case he had presented at Purdue; so he really got clobbered on those arguments. Because he wasn’t prepared for my new arguments, he didn’t even respond to two of my arguments for the beginning of the universe, though he did a credible job responding to the others. I was pleased when he attacked the Big Bang by quoting the same scientist as before, because I then held up the book, specified the page number, and proceeded to quote the context to show what the scientist really meant.

Dr. Craig is always prepared!

Polemics

What should Christians bring up when discussing truth with Muslims?

8 Comments

I have some experience dicussing Islam because my mother’s side of the family is all Muslim. My go-to argument has always been to confront them about the Qur’an’s claim that Jesus did not die of crucifixion. But I noticed a different argument from Laura Powell, who knows far more about this topic than I do. Do you think her approach is the best one?

She writes about it over at her blog, An Affair with Reason:

The crux of the argument is this: The Qur’an affirms the inspiration, authority, and preservation of the New Testament Gospels;[2] yet the Qur’an also contradicts the Gospels on major theological and historical points. Therefore, the Qur’an cannot be reliable.

According to the Qur’an, the Gospel is the trustworthy, reliable revelation of God given as a guidance for mankind (Qur’an 3:3-4). These Scriptures from God were available and trustworthy when the Qur’an was revealed in the 7th century A.D., and those who had access to them were repeatedly told to obey them, judge by them, submit to their teaching, and stand fast upon them. In other words, according to the Qur’an, the Gospels are the inspired and authoritative words of God.

Qur’an 5:47 says, “And let the People of the Gospel judge by what Allah has revealed therein. And whoever does not judge by what Allah has revealed—then it is those who are the defiantly disobedient.”

Furthermore, Qur’an 5:68 states, “Say, ‘O People of the Scripture, you are [standing] on nothing until you uphold [the law of] the Torah, the Gospel, and what has been revealed to you from your Lord’” (see also 6:114; 3:3-4).

What I like about her argument is that she’s just taking the words of the Qur’an seriously, and asking the Muslims who claim to believe it what’s going on here. Why say that the gospels are unreliable today, when the Qur’an said that the gospels were reliable, yesterday.

My argument about the death of Jesus requires us to ask Muslims “where is the non-Muslim historian who thinks that Jesus did not die?” There isn’t one.

But my argument requires that the Muslim know something about historical scholarship, to know what non-Muslim historians think.Laura’s argument has wider appeal, because it doesn’t require that the Muslim have any knowledge about history – only knowledge about what their own holy book says.

She concludes with this:

What we see here is that the Qur’an teaches the inspiration, authority, and preservation of the Gospels. The Qur’an was intended as an Arabic version of the message of truth found in the Jewish and Christian Scriptures, but this presents a huge problem for Muslims because the Qur’an contradicts the Christian Scriptures on essential doctrines. Most notably, the Qur’an teaches that Jesus was not God incarnate, he did not die on a cross, and he was not raised from the dead (Qur’an 4:157; 5:116).

Here’s the dilemma for Muslims: If the Gospels are not trustworthy, then the Qur’an is false because it teaches that the Gospels are the inspired, perfectly preserved, authoritative words of God. But if the Gospels are trustworthy, then the Qur’an is false because it teaches contradictory, mutually exclusive facts about key issues. Either way, the Qur’an is false.

This, of course, is a huge problem for Muslims. The validity of Islam rests upon the reliability of the Qur’an, just as Christianity rests upon the truth of the divinity, death, and resurrection of Jesus. If the Qur’an is unreliable, then Islam is a false religion.

I like that she’s comfortable having disagreements with people. That’s not very common in the church today, in my experience.

By the way, this is the same Laura who wrote that really good article about how she found a better way to discuss her Christian worldview when she moved on from sharing her testimony. I blogged about it here.

William Lane Craig lectures on naturalistic alternatives to the Big Bang

3 Comments

Here’s the lecture, which was given in 2004 at the University of Colorado, Boulder.

This lecture might be a little advanced for beginners, but if you stretch your mind first, you shouldn’t tear anything. (Note: standard disclaimers apply if you do tear something!)

The description of the video states:

This is quite simply one of the best lectures William Lane Craig (a philosopher of science) has given. Craig explores the origins of the universe. He argues for a beginning of the universe, while refuting scientific models like the Steady State Theory, the Oscillating Theory, Quantum Vacuum Fluctuation Model, Chaotic Inflationary Theory, Quantum Gravity Theory, String Theory, M-Theory and Cyclic Ekpyrotic Theory.

And here is the description of the lecture from Reasonable Faith:

A Templeton Foundation lecture at the University of Colorado, Boulder, laying out the case from contemporary cosmology for the beginning of the universe and its theological implications. Includes a lengthy Q & A period which features previous critics and debate opponents of Dr. Craig who were in attendance, including Michael Tooley, Victor Stenger, and Arnold Guminski.

Craig has previously debated famous atheists Stenger and Tooley previously. And they both asked him questions in the Q&A time of this lecture. Imagine – having laid out your entire case to two people who have debated you before and who know your arguments well. What did they ask Craig, and how did he respond?

The scientific evidence

The Big Bang cosmology that Dr. Craig presents is the standard model for how the universe came into being. It is a theory based on six lines of experimental evidence.

Scientific evidence:

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

It’s probably a good idea to be familiar with these if you are presenting this argument, because experimental science is a reliable way of knowing about reality.

Published research paper

This lecture by Dr. Craig is based on a research paper published in an astrophysics journal, and was delivered to an audience of students and faculty, including atheist physicist Victor Stenger and prominent atheist philosopher Michael Tooley, at the University of Colorado at Boulder.

Here’s the peer-reviewed article that the lecture is based on.

Here’s the abstract:

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