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!

What is the fine-tuning argument for God’s existence, and does the multiverse counter it?

One of the best arguments for the existence of a Creator and Designer of the universe is the cosmic fine-tuning argument. The argument argues that individual constants and quantities in nature cannot be much smaller or larger than they are, because it would remove the ability of the universe to support life of any kind. Dr. Michael Strauss, an experimental physicist, explains some examples of the fine-tuning in a recent post on his blog.

He writes:

I liken the finely-tuned universe to a panel that controls the parameters of the universe with about 100 knobs that can be set to certain values. If you turn any knob just a little to the right or to the left the result is either a universe that is inhospitable to life or no universe at all.

Consider the knob that controls the strength of the strong nuclear force that holds quarks inside the neutrons and protons and binds the nucleus of the atom together. If the strength were increased by 2%, the element hydrogen would be either non-existent or very rare. Without hydrogen there would be no water (H2O) or stars that burn hydrogen as their nuclear fuel like our sun.  Without hydrogen there would be no life. If the strength of the strong nuclear force were decreased by about 5%, then hydrogen would be the only element in the universe. That would simplify the periodic table and make Chemistry class very easy, but it would render life impossible.

All known life in this universe is based on the element carbon, which is formed in the final stages of a star’s life. The carbon you and I are made of is the result of the nuclear processes that occurred as previous stars ended their lives. One nice recent study showed that if the mass of the quarks that make up neutrons and protons were changed by just a few percent, then the process that makes carbon as stars die would be altered in such a way that there would not be sufficient carbon in the universe for life. The masses of the lightest sub-atomic quarks are the precise value that is required for carbon to form and for life to exist.

Regarding the multiverse, let me just quote from MIT physicist Alan Lightman, writing in Harper’s magazine about the multiverse:

The… conjecture that there are many other worlds… [T]here is no way they can prove this conjecture. That same uncertainty disturbs many physicists who are adjusting to the idea of the multiverse. Not only must we accept that basic properties of our universe are accidental and uncalculable. In addition, we must believe in the existence of many other universes. But we have no conceivable way of observing these other universes and cannot prove their existence. Thus, to explain what we see in the world and in our mental deductions, we must believe in what we cannot prove.

Sound familiar? Theologians are accustomed to taking some beliefs on faith. Scientists are not. All we can do is hope that the same theories that predict the multiverse also produce many other predictions that we can test here in our own universe. But the other universes themselves will almost certainly remain a conjecture.

The multiverse is not pure nonsense, it is theoretically possible.But even if there were a multiverse, the generator that makes the universes itself would require fine-tuning, so the multiverse doesn’t get rid of the problem. And, as Lightman indicates, we have no independent experimental evidence for the existence of the multiverse in any case. Atheists just have to take it on faith, and hope that their speculations will be proved right. Meanwhile, the fine-tuning is just as easily explained by postulating God, and we have independent evidence for God’s existence, like the the origin of biological information, the sudden appearance of animal body plans, the argument from consciousness, and so on. Even if the naturalists could explain the fine-tuning, they would still have a lot of explaining to do. Theism (intelligent causation) is the simplest explanation for all of the things we learn from the progress of science.

It’s very important to understand that if these values were any different, then it’s not like we would bridges on our foreheads, or have green skin, or have pointy ears, etc. That’s what science fiction teaches you. And many atheists form their view of science by watching science fiction entertainment. But the truth is that the consequences of changing these values are much more consequential: no stars, no planets, no hydrogen, no heavy elements, the universe re-collapses into a hot fireball. You’re not going to have complex, embodied intelligent agents running around making moral decisions and relating to God in a world like that.

Questions like the existence of God should be decided by feelings and faith and superstitious nonsense. They ought to be decided by evidence. Specifically, scientific evidence. Everyone has to account for this scientific evidence for fine-tuning within their worldview, and they have to account for it in a way that is responsible and rational. Punting to the multiverse, without any evidence for it, is neither rational nor responsible. Holding out hope that the evidence we have now will all go away is neither rational nor responsible.

Bible study: why would a loving God make a terrible place like Hell?

Bible study that hits the spot
Bible study that hits the spot

It’s time for us to take a look in the Bible and make some sense of it, again. Today’s question is really “what does God expect us to be doing with our lives?” but I wanted the title of this post to be more eye-catching for non-Christians.

Why do people go to Hell?

Let’s start with finding out what we are supposed to be doing, and then we’ll know why there is a place like Hell for people who don’t do that to be separated from God.

Everyone has a moral obligation to choose how to use their time wisely during their life time. People everywhere, in all times and places, have had the choice of whether to spend more time thinking about the “big questions” or more time having fun and being selfish. Thinking about the big questions logically leads a person to making discoveries about God’s existence and character. Once the people who think about the “big questions” discover the answers to those big questions, they are morally obligated to use their free will to love God using all their capabilities.

Bible verse break:

Deuteronomy 4:27-30:

27 The Lord will scatter you among the peoples, and only a few of you will survive among the nations to which the Lord will drive you.

28 There you will worship man-made gods of wood and stone, which cannot see or hear or eat or smell.

29 But if from there you seek the Lord your God, you will find him if you seek him with all your heart and with all your soul.

30 When you are in distress and all these things have happened to you, then in later days you will return to the Lord your God and obey him.

At a bare minimum, loving God also means obeying the moral law. But I think there is a lot more to loving God than just obeying rules. Each person is also obligated to engage in and support enterprises that help others to know God as he really is. If a person fails to use their free will to love God, then that person is sinning. Notice that on my view, being nice to your neighbor is relatively unimportant compared to being nice to God. Jesus’ first commandment is to love God, and that vertical dimension is much more important than horizontal dimension of loving your neighbor.

Bible verse break, again – this time Paul is explaining what he does to love God:

Philippians 1:3-19:

3 I thank my God every time I remember you.

4 In all my prayers for all of you, I always pray with joy

5 because of your partnership in the gospel from the first day until now,

6 being confident of this, that he who began a good work in you will carry it on to completion until the day of Christ Jesus.

7 It is right for me to feel this way about all of you, since I have you in my heart and, whether I am in chains or defending and confirming the gospel, all of you share in God’s grace with me.

8 God can testify how I long for all of you with the affection of Christ Jesus.

9 And this is my prayer: that your love may abound more and more in knowledge and depth of insight,

10 so that you may be able to discern what is best and may be pure and blameless for the day of Christ,

11 filled with the fruit of righteousness that comes through Jesus Christ—to the glory and praise of God.

12 Now I want you to know, brothers and sisters, that what has happened to me has actually served to advance the gospel.

13 As a result, it has become clear throughout the whole palace guard and to everyone else that I am in chains for Christ.

14 And because of my chains, most of the brothers and sisters have become confident in the Lord and dare all the more to proclaim the gospel without fear.

15 It is true that some preach Christ out of envy and rivalry, but others out of goodwill.

16 The latter do so out of love, knowing that I am put here for the defense of the gospel.

17 The former preach Christ out of selfish ambition,not sincerely, supposing that they can stir up trouble for me while I am in chains.

18 But what does it matter? The important thing is that in every way, whether from false motives or true, Christ is preached. And because of this I rejoice.

Yes, and I will continue to rejoice,

19 for I know that through your prayers and God’s provision of the Spirit of Jesus Christ what has happened to me will turn out for my deliverance.

So we are supposed to be telling people the gospel, which is the good news about who God is, and what he has done for us to bring us into a right relationship with him, despite our lack of curiosity about him, and our focus on ourselves instead of him. The pre-condition to loving God and sharing the gospel is knowing what his character is really like. Most people are born into a certain religion or learn it from their parents or their culture and they either adopt it without thinking or they reject it without thinking. They are not interested in investigating who God is using reason and evidence, including scientific and historical evidence.

On the Christian view, the best thing you can possibly do with your time is to investigate whether God is real, and what he is like. It’s wrong to say that investigating doesn’t matter or that all religions are the same. In fact, when you actually look into these things like you do any other area of knowledge, with logic and evidence, you do arrive at knowledge of who God is. And that’s because God has left clues of who he is in the natural world and in history – he expects us to be looking for him. He is as real as any other person you know, and his character is as defined as any other person you know.

Bible verse break:

Acts 17:26-27:

26 From one man he made all the nations, that they should inhabit the whole earth; and he marked out their appointed times in history and the boundaries of their lands.

27 God did this so that they would seek him and perhaps reach out for him and find him, though he is not far from any one of us.

I think that the result of any honest investigation is going to be that the Christian religion is going to be found to be more true in its major claims than any other religion. I.e. – people who conduct an honest investigation are going to find that the Christian claims about the universe coming into being out of nothing, and of Jesus rising from the dead, etc. will be validated by the progress of science and historical inquiry.

But since people have a natural tendency to focus on making themselves happy, not many investigations occur. They know that if Christianity is true, they would have to engage in radical self-denial and self-sacrificial love. They know they would have to sober, be chaste, be different, and not be liked because of their exclusive view. And people don’t want to do that, so an honest investigation never even gets started.

Instead, what you find non-Christians doing is hoping in speculations to justify their flight from the demands of the God who is there. We want to be free to make ourselves happy, and that means that we have to keep the real God who is there and who is not silent at arms length. That’s what non-Christians do – they use their time on Earth to push God away so they can focus on themselves and their own happiness. In fact, even Christians do it, which is why we rely on Jesus as a sacrifice for our sin. We could come near to God and work on the things that he would like us to work on without some way to get past our own rebellion. For those who grasp the sacrifice of Jesus as an atonement for our rebellion, cooperation with God becomes possible.

One of the problems that Christians have today is that we do not really understand what sin is. We think that sin is about hurting other people or making other people feel bad. But actually, the sinfulness of a person has little to do with that, and much more to do with how we respond to God. We have a moral obligation to know God and to include God in all of our decision making. Hell is the place that God has made for people who turn away from him. A person chooses Hell when she refuses to investigate whether God is there and who God is, so that she does not have to adjust her choices to respect God.
