William Lane Craig lectures on naturalism at the University of St. Andrews

Lets take a closer look at a puzzle

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.

Dr. Craig was in Scotland to lecture at a physics conference, but a local church organized this public lecture at the University of St. Andrews.

Here is the full lecture with Q&A: (2 hours)


  • 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

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.

Questions and Answers

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.

Is Christianity false or is it just mean and judgmental?

Have you noticed lately that there is a decided lack of atheists who argue against Christianity on factual grounds? Instead of constructing arguments against Christian theism, what I am seeing more and more of is that people try to say that Christianity makes some group feel bad, and therefore Christianity is not worthy of pursuit and engagement.

Here’s how it works. You have a person who has some sinful habit or other that they don’t want to give up, and they notice that people are judging them and saying that what they are doing is wrong. And they feel bad. And they decide to attack Christianity to make the Christians stop judging them. So how do they do it? Do they argue that the concept of God is logically incoherent? No… Do they argue that some instances of evil and suffering are gratuitous? No… Do they argue that the universe is eternal so that it had no Creator? No…

What do they do?

What they do is pick on some statement by a conservative Christian that makes them feel bad, and then claim that they are victims of meanness. And apparently, making someone feel bad is some sort of disproof of Christian theism. Why is that? It’s because we have decided as a culture that the purpose of religion is to make people feel good about themselves and to be “nice” to other people. And by “nice”, we mean not making other people feel bad about the sinfulness of their behavior. So people are making Christianity irrelevant just by assuming that the purpose of life is happiness, and that any religion that makes people unhappy can be dismissed.

Before, people thought about Christianity as something that you investigated, and that was either true or false. People understood that Christianity made claims about the external world that were either true or false. For example, Christianity claims that the universe had a beginning in the finite past. And the people who disagreed with Christianity would try to produce arguments and evidence that the universe was eternal, as with the steady-state theory or the oscillating model of the universe. And people were willing to change their behavior to match what was true, even when it made them feel less happy. But not any more.

Religion today is not about truth

I think somehow, as a society, we have internalized the following beliefs:

  • God wants me to have happy feelings
  • the purpose of religion is to give me happy feelings
  • God’s moral will for me is that I be “nice” to others
  • being nice to others means accepting whatever they want to do as “good”
  • accepting whatever anyone does makes them like me
  • when people like me, I feel happy, which is what God wants
  • there is no need for me to study God’s existence
  • God exists when I want to be comforted, and doesn’t exist when I want to sin
  • there is no need for me to study God’s character
  • God’s character is pretty much like my character, whatever I want is fine with God
  • there are no moral rules or obligations from God that apply to me
  • religions are all the same, I choose the one that makes me feel happy

So you can see that someone who believes things like this can claim to be a Christian, but would actually attack real Christians who hold to the old view of exclusive factual claims and moral judgments. The real Christians are people who have studied these questions, who know that God exists, and what he is like, and accept the Bible’s moral teachings as authoritative. So you could have a famous pastor who defends the Bible’s prohibition on sex before marriage, and have someone feel bad about being judged, and then a bunch of these “the purpose of life is happiness” people will appear and chastise that pastor for making people feel bad. And many of them will claim to be Christians, and attend church, too.

Now notice that this mob of happy-feelings people are not going argue against the pastor using the Bible, because the Bible is pretty clearly against fornication. What they’ll do instead is they’ll pick out some piece of the Bible that seems unfair, like the slaughter of some group of child-sacrificing pagans, and they’ll rail against that Bible passage in order to discredit the Bible’s authority on moral questions. And then the good conservative pastor is made to feel bad because he has broken those unwritten laws – he made someone feel bad using this evil book.

No factual claims about God’s existence were made. No historical arguments were made. No evidence was presented. The mere fact that the Bible is mean to talk about killing the poor Canaanites is used to prove that the Bible has no moral authority at all, on any issue. “It’s mean” entails that it’s false. And you can have people who read the Bible for devotions, who sing in church, and who lead worship, who think that the Bible is false because it’s mean, and it’s mean because it can be used to judge people and make them feel bad.

An example

Now consider single motherhood, as in this case.


She tells her children to do as she says and not as she does.

But the words of mother of 14 Joanne Watson – who receives more than £2,000 a month in state handouts – have fallen on deaf ears.

Her 15-year-old daughter Mariah is pregnant, the father has ‘left the scene’, and the youngster is about to start living off benefits.

Mrs Watson, 40, is raising her giant brood alone after parting from her husband John, 46, three years ago, and breaking up with subsequent partner Craig le Sauvage, 35, last year.

Despite this, she has still managed to squirrel away enough cash for a £1,600 breast enhancement and a sunbed. She claims she has always encouraged her daughters to use contraception – but, inevitably, it seems they would rather follow the family tradition.

Mariah’s pregnancy comes after Mrs Watson’s oldest daughter Natasha, 22, got pregnant with her son Branford, now six, when she was 16. Her second eldest daughter Shanice, 19, also got pregnant at 16 with her 22-month-old son Marley.

Mariah says she has no concerns about becoming a teenage mother, as it seems the most natural thing in the world. Initially, she and her child will be supported by the taxpayer.

She is expected to move into a housing complex for single mothers and will receive supplementary benefit and child allowance for her baby.

The youngster, who is due to have a boy, said: ‘I’m not nervous. I’ve been around babies my whole life so I know what to expect and that I can handle it. The father isn’t involved and I don’t want him to be either. I’m really excited and think I will be a great mum.’

Now there are two responses to this from people who profess to be Christians. The first response, my response, is to make a general argument against having sex before marriage, using the latest statistics to show the harm that fatherlessness causes to children, and more evidence besides. My response is not to pick on any one person, but to set moral boundaries, to make moral judgments against the selfishness of parents, and to not celebrate and subsidize anything that will harm innocent children. I don’t want to make anyone person feel bad, I just want to say what the evidence is. However, even a general argument using evidence does make some people feel bad, so I am judged as “mean” for giving my opinion and backing it up with evidence.

But there is another response. This response comes from someone who professes to be a Christian, but they are actually a “God wants me to be happy and to be nice to people so they will like me and then we’ll all be happy” person. They would never dream of judging anyone for anything they do. And they are very angry with me for getting my moral rules out of that horrible Bible, and for using facts and evidence to make people feel bad. They believe in compassion, which is the idea that says that the moral boundaries of the Bible are false, and that we have to celebrate and subsidize any and every variation on the traditional family, regardless of the harm caused, so that the selfish adults don’t feel bad about their destructive choices.

And what do we make of a person who feels that saying “it’s wrong” is mean, because it makes a guilty person feel bad? Well, here is the truth. A person who argues against the Bible based on the happy-feelings model is no friend of God, and no friend of the victims of selfish actions. They may think that they are being a good person by affirming people who make bad decisions, but really it just encourages people to get into trouble.

The kalam cosmological argument defended in a peer-reviewed science journal

Christianity and the progress of science
Christianity and the progress of science

Here’s the peer-reviewed article. It appears in a scientific journal focused on astrophysics.

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.

The whole text of the article is posted online here.

Here’s an excerpt in which the author, Dr. William Lane Craig, explains the Big Bang cosmology:

The monumental significance of the Friedman-Lemaitre model lay in its historization of the universe. As one commentator has remarked, up to this time the idea of the expansion of the universe “was absolutely beyond comprehension. Throughout all of human history the universe was regarded as fixed and immutable and the idea that it might actually be changing was inconceivable.”{8} But if the Friedman-Lemaitre model were correct, the universe could no longer be adequately treated as a static entity existing, in effect, timelessly. Rather the universe has a history, and time will not be matter of indifference for our investigation of the cosmos. In 1929 Edwin Hubble’s measurements of the red-shift in the optical spectra of light from distant galaxies,{9} which was taken to indicate a universal recessional motion of the light sources in the line of sight, provided a dramatic verification of the Friedman-Lemaitre model. Incredibly, what Hubble had discovered was the isotropic expansion of the universe predicted by Friedman and Lemaitre. It marked a veritable turning point in the history of science. “Of all the great predictions that science has ever made over the centuries,” exclaims John Wheeler, “was there ever one greater than this, to predict, and predict correctly, and predict against all expectation a phenomenon so fantastic as the expansion of the universe?”{10}

As a GTR-based theory, the Friedman-Lemaitre model does not describe the expansion of the material content of the universe into a pre-existing, empty, Newtonian space, but rather the expansion of space itself. This has the astonishing implication that as one reverses the expansion and extrapolates back in time, space-time curvature becomes progressively greater until one finally arrives at a singular state at which space-time curvature becomes infinite. This state therefore constitutes an edge or boundary to space-time itself. P. C. W. Davies comments,

An initial cosmological singularity . . . forms a past temporal extremity to the universe. We cannot continue physical reasoning, or even the concept of spacetime, through such an extremity. . . . On this view the big bang represents the creation event; the creation not only of all the matter and energy in the universe, but also of spacetime itself.{11}

The popular expression “Big Bang,” originally a derisive term coined by Fred Hoyle to characterize the beginning of the universe predicted by the Friedman-Lemaitre model, is thus potentially misleading, since the expansion cannot be visualized from the outside (there being no “outside,” just as there is no “before” with respect to the Big Bang).{12}

The standard Big Bang model thus describes a universe which is not eternal in the past, but which came into being a finite time ago. Moreover,–and this deserves underscoring–the origin it posits is an absolute origin ex nihilo. For not only all matter and energy, but space and time themselves come into being at the initial cosmological singularity. As Barrow and Tipler emphasize, “At this singularity, space and time came into existence; literally nothing existed before the singularity, so, if the Universe originated at such a singularity, we would truly have a creation ex nihilo.“{13}

[…]On such a model the universe originates ex nihilo in the sense that at the initial singularity it is true that There is no earlier space-time point or it is false that Something existed prior to the singularity.

Every theist should be able to understand and defend this argument. It is a scientific refutation of materialism, and it is supported by six lines of scientific evidence – all of which emerged as science has progressed.

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

Those are the scientific discoveries that have led us to the beginning of the universe, which support’s Dr. Craig’s argument.

This is the kind of evidence I expect all Christian theists to be using when discussing the question of whether God exists. Scientific evidence. When talking to non-Christians, we first need to show that we understand science, because science is a reliable and respected way of getting knowledge about the universe. Non-Christians do not accept the Bible, but they do accept science, so we begin evangelism with science. Science (experimental, testable, repeatable science) should set limits on what anyone can believe – including non-Christians, who might otherwise not be inclined to listen to Bible verses and theology. Important: it’s not a good idea to discuss the resurrection of Jesus with a person who does not accept the scientific evidence for a Creator of the universe.

The Big Bang is not compatible with atheism

According to the Secular Humanist Manifesto, atheism is committed to an eternally existing universe, (See the first item: “Religious humanists regard the universe as self-existing and not created.”). If something non-material brought all existing matter into being, that would be a supernatural cause, and atheists deny that anything supernatural exists. The standard Big Bang theory requires that all the matter in the universe come into being out of nothing. This falsifies eternal models of the universe, which are required by the atheistic worldview.
