How to defend the kalam cosmological argument just like William Lane Craig

UPDATE: Welcome readers from The Way the Ball Bounces! Thanks for the link!

UPDATE: Welcome visitors from Colliding Universes! Thanks for the link Denyse!

This post is the first in a two part series. In case you missed it, here is Craig’s second argument about fine-tuning.

I’ve been watching Bill Craig debates for a long time now, ever since I did my first degree in computer science a dozen years ago. Today I thought we could all learn how to argue Craig’s first argument for God, which he used in his debate with Christopher Hitchens.

Let’s go over Craig’s kalam argument in brief.

The kalam cosmological argument

The argument goes like this:

  1. Whatever begins to exist requires a cause
  2. The universe began to exist
  3. Therefore, the universe requires a cause (M.P. 1,2)

The most important thing for you to realize is that nothing can be sustained in a debate unless it can be phrased as a valid argument according the rules of inference. All of Craig’s arguments can be broken down into logical propositions that use the standard laws of logical reasoning in order to force their conclusions deductively, so long as the premises are true.

Understanding the logical form of the kalam argument

The form of the kalam argument is valid because it allows for a modus ponens inference. (Here’s a primer on logical reasoning)

  • if p is true, then q is true
  • p is true
  • therefore, q is true

That means that so long as premise 1 and 2 are true, the conclusion follows necessarily. This is the same form of argument (deductive) used by Sherlock Holmes in his cases.

Proving the premises

Can the atheist deny that either or both of these premises are true?

  1. “Whatever begins to exist requires a cause”
    If the atheist denies this premise, then they are denying a fundamental law of natural science, namely, that matter can neither be created or destroyed. That is natural law.
  2. “The universe began to exist”
    The universe came into being. If the atheist denies this they are denying the state of the art in modern cosmology.

First, quantum mechanics is not going to save the atheist here. In QM, virtual particles come into being in a vacuum. The vacuum is sparked by a scientist. The particles exist for a period of time inversely proportional to their mass. But in the case of the big bang, there is no vacuum – there’s nothing. There is no scientist – there’s nothing. And the universe is far too massive to last 14 billion years as a virtual particle.

Secondly, atheists will say that the big bang is speculative physics that could change at any moment. But the trend is in favor of an absolute beginning out of nothing. We have had a string of solid, recent scientific discoveries that point in a definite direction, as follows:

  • Einstein’s theory of general relativity, and the scientific confirmation of its accuracy
  • the cosmic microwave background radiation
  • red-shifting of light from galaxies moving away from us
  • radioactive element abundance predictions
  • helium/hydrogen abundance predictions
  • star formation and stellar lifecycle theories
  • the second law of thermodynamics applied to nuclear fusion inside stars

So, insofar as atheists question these discoveries and the origin of the entire physical universe out of nothing, they are opposing the progress of science.

What came into being at the moment of creation?

You need to understand that the big bang theory states that space, time and matter were all created at the moment of creation.

  1. There was no space causally prior to the universe beginning to exist
  2. There was no time causally prior to the universe beginning to exist
  3. There was no matter causally prior to the universe beginning to exist

All of these things began to exist at the first moment.

What can we infer about the cause?

So, space, time, and matter began to exist. What could have caused them to begin to exist?

  1. Whatever causes the universe to appear is not inside of space, because there was no space causally prior to the creation event. The cause must therefore be non-physical, because physical things exist in space.
  2. Whatever causes the universe to appear is not bound by time (temporal). It never began to exist. There was no passage of time causally prior to the big bang, so the cause of the universe did not come into being. The cause existed eternally.
  3. And the cause is not material. All the matter in the universe came into being at the first moment. Whatever caused the universe to begin to exist cannot have been matter, because there was no matter causally prior to the big bang.

So what could the cause be? Craig notes that we are only familiar with two kinds of non-material realities:

  1. Abstract objects, like numbers, sets and mathematical relations
  2. Minds, like your own mind

Now, abstract objects don’t cause of any effects in nature. But we are very familiar with the causal capabilities of our own minds – just raise your own arm and see! So, by process of elimination, we are left with a mind as the cause of the universe. As Sherlock Holmes says, “When you have eliminated the impossible, whatever remains, however improbable, must be the truth.

This cause created the entire physical universe. The cause of this event is therefore supernatural, because it brings nature into being and is not inside of nature itself. The cause of the universe violates the law of conservation of matter is therefore performing a miracle.

Responding to alternative naturalistic cosmologies

In this published research paper from the journal Astrophysics and Space Science, William Lane Craig responds to the several naturalistic attempts to evade the implications of the kalam argument. I will list each one by name and explain the main problem with each. I highly recommend you read the paper and become conversant with the arguments and evidences.

  1. The steady-state model: disproved by recent empirical observations of radio galaxy distributions, as well as red-shifting of light from distant galaxies moving away from us at increasing speeds
  2. The oscillating model: disproved in 1998 by more empirical measurements of mass density which showed that the universe would expand forever, and never collapse (was named Discovery of the Year)
  3. The vacuum fluctuation model: the theory allows for universes to spawn at every point in space and coalesce into one extremely old universe, which contradictions observations of our much younger universe
  4. The chaotic inflationary model: does not avoid the need for an absolute beginning in the finite past
  5. The quantum gravity model: makes use of imaginary time which cannot be mapped into a physical reality, it’s purely theoretical

Why the kalam cosmological argument matters

We need to make a decision today about how we are going to live. The evidence available today supports the creation of the entire physical universe from nothing, caused by a supernatural mind with immense power. The progress of science has strengthened this theory against determined opposition from rival naturalistic theories.

Those are the facts, and we must all choose what to do with them.

Further study

A good on this topic is the debate between William Lane Craig and atheist physicist Victor Stenger, (audio here). Also, a lecture titled “Beyond the Big Bang”, was delivered at the University of Colorado at Boulder, in front of Victor Stenger and other physicists (audio here). There is a period of Q&A in which Bill must face challengers. These are both available on DVD. More Bill Craig debates are here.

Are all religions basically the same?

UPDATE: Welcome visitors from The Western Experience! Thanks for the link, Jason!

I’m sure that all my readers will have noticed that there a huge number of different religions in the world. This is called religious pluralism. Religions all make claims about the way the universe is, and the way that we ought to act in order to solve the problems that we all face as human beings.

The law of non-contradiction

To start with, we all need to be familiar with the law of non-contradiction. This is the stuff that software engineers all learned in undergraduate computer science courses. Computer science is a lot like analytical philosophy because both study symbolic logic. Analytical philosophy is as rigorous as mathematics.

The law says that for any proposition P, P cannot be true and not true at the same time, and in the same context. For example, let P be the statement “it is raining outside my window right now”. It is impossible that the reality of the world be that it is raining outside my window right now, and not raining outside my window right now.

The external world is shared by all of us, and it is objective (it is not affected by what we think about it). When we make propositional claims, it is the external, mind-independent world that makes claims true or false. And by “world” I mean all of reality, past, present and future.

Similarities between religions

On a superficial level, religions are similar because they all try to answer the same kinds of questions:

  • what is the nature of the ultimate reality in the universe?
  • what is the fundamental problem faced by human beings?
  • what should human beings do to solve this problem?

These questions are shared by all religions, but on a more fundamental level, religions are all completely different because they give mutually exclusive answers to these questions. Therefore, according to the law of non-contradiction, they cannot all be true at the same time and in the same context.

Differences between religions

In this post, blogger Neil explains how the Christian Bible claims that Jesus died on a cross, but the Koran claims he did not die on a cross. How do we understand these two contradictory claims? Are they propositional truth claims about the external world, or something else? There are two answers.

Postmodernism: Treating religious claims as subjective nonsense

We could say that all religious claims are just nonsense, and are not intended to apply to the external world, but are just personal preference claims about each believer – they are neither true nor false. The problem is that the postmodernist is then being condescending to the religious adherent by redefining their own words.

Rationality: Treating religions claims as genuine claims about reality

We could instead avoid insulting believers by being condescending about their claims. We could say that all religious claims are exactly what the believers claim they are: real claims about the external world. We could then resolve the conflicts using the same tools we use in our everyday lives: the laws of logic and empirical evidence.

How do postmodernists reinterpret religious claims as non-propositional?

Here are a few ways that postmodernists reinterpret the conflicting claims of different religions:

  1. relativism: you reinterpret truth claims of the different religions so that they are claims of personal preference, which express the deluded myths that each individual religious person finds “fetching”
  2. pragmatism: you reinterpret truth claims of the different religions so that they are claims of personal selfishness, so that each religious believer chooses the delusion that is personally satisfying to them
  3. syncretism: you re-interpret truth claims of the different religions so that claims that are absolutely central, such as “was Jesus God?” are reinterpreted as being peripheral issues, and then the religions can all agree on the core of religious belief, such as advocacy of socialism, global warming and abortion

Why would postmodernists want to treat religious claims as nonsense?

In addition to the desperate desire to keep God from having authority over our moral decision-making (i.e. – sin, rebellion, etc.), there are 3 reasons why people try to treat religious claims as non-propositional nonsense.

  1. Ignorance: people do not know the conflicting truth claims that different religions make
  2. Laziness: people do not want to have to spend time evaluating the competing truth claims
  3. Cowardice: people do not want to investigate and debate truth claims: it makes them unpopular

Postmodernists have decided that the purpose of life is to be hedonistic, and not to worry about the world really is. They think that trying to find out the truth about our origins, our purpose, and our ultimate fate is hard work, and talking about it makes them unpopular. So they don’t want to do it.

But that is not what they say when you ask them. Instead, they say that disagreements about religion has caused a lot of wars, and so it’s better if we just reduce the question of truth in religion to personal preference. That way, everyone can choose the delusion that makes them happy, (although religions are all actually false).

But postmodernists are arrogant to redefine the claims of all religions as nonsense. And it is self-refuting because they are substituting their own view of religion as objectively true, which is just what they deny everyone else. And if disagreeing about religion causes wars, then why are they disagreeing with us about religion?

So then how do we deal with the plurality of religions?

The answer is to treat religion the exact same way as any other area of knowledge. We can tolerate people’s right to disagree, disagree while still being polite, and resolving disputes using logic, and evidence supplied from disciplines such as analytical philosophy, scientific investigation, and historical analysis.

People who want to involve emotion and intuition in the process of testing the conflicting religious claims can just butt out of the conversation. The search for truth should proceed irrespective of what you think about the truth claims of religion. Yes, the doctrine of Hell offends people, but that doesn’t make it false.

Further study

Portions of this article were borrowed from this lecture by philosopher Douglas Groothuis, in which he explains the how to think carefully, using the laws of logic, about religious claims and the fact of religious pluralism. Note that Doug is a lot less snarky than I am in the lecture.

Also, I noticed that Unbelievable has posted a debate between Muslim Shabir Ally and Christian Tony Costa on whether Jesus dried on a cross and whether he rose from the dead.

Here are some related posts on the question of postmodernism and testing religious claims. All of them are far, far, far less snarky than my post today.

Gary Habermas explains the earliest source of resurrection facts

UPDATE: Welcome, visitors from Free Canuckistan! Did you know that Binks is a web elf? It’s true!

UPDATE: Western Experience has video of Gary Habermas in action here.

UPDATE: Welcome, visitors from Stand to Reason! Thanks for the link, Melinda!

Do you just skim right over 1 Corinthians 15:3-7 when you read your Bible? Did you know that this passage is the best passage in the entire Bible when it comes to defending the resurrection? Let’s take a look at a lecture where historian Gary Habermas explains the importance of 1 Corinthians 15:3-7 for defending the bodily resurrection of Jesus as a historical event.

Recall that there are certain criteria for deciding what passages of the New Testament writings are historically reliable. Here is a great article from Gary Habermas that explains all of the criteria. Below, I’ll list some of the criteria from that article.

Early attestation

Early sources include: 1) 7 of the 13 Pauline books that are unanimously accepted as being authored by Paul, 2) the “Q” passages which are shared by Matthew and Luke, but that are not in Mark, and 3) certain short creedal passages from the book of Acts. The 7 reliable Pauline epistles are Romans, 1 Corinthians, 2 Corinthians, Philipians, 1 Thessalonians, Galatians and Philemon.

Habermas writes:

With regard to the historical Jesus, any material between 30 and 50 AD would be exemplary, a time period highly preferred by scholars like those in the Jesus Seminar.

Reports from such an early date would actually predate the written Gospels. A famous example is the list of Jesus’ resurrection appearances supplied by Paul in 1 Corinthians 15:3-8. Most critical scholars think that Paul’s reception of at least the material on which this early creedal statement is based is dated to the 30s AD. Other examples are supplied by the brief creedal statements that many scholars find embedded within the Book of Acts, which Gerald O’Collins dates to the 30s AD. From the so-called “Q” material in the first and third Gospels, another instance is the statement of high Christology found in Matthew 11:27/Luke 10:22. Further, Paul’s earliest epistles date from the 50s AD.

Eyewitness testimony

Habermas writes:

Whenever these early sources are also derived from eyewitnesses who actually participated in some of the events, this provides one of the strongest evidences possible. Historian David Hackett Fischer dubs this “the rule of immediacy” and terms it “the best relevant evidence.” When scholars have ancient sources that are both very early and based on eyewitness testimony, they have a combination that is very difficult to dismiss.

In our previous example, one reason critical scholars take Paul’s testimony so seriously is that his writings provide both a very early date as well as eyewitness testimony to what Paul believed was a resurrection appearance of Jesus. This is even conceded by atheist scholar Michael Martin. Other crucial instances would concern any eyewitness testimony that can be located in the Gospel accounts.

Multiple attestation

Habermas writes:

Independent attestation of a report by more than one source is another chief indication that that a particular claim may be factual. Ancient historian Paul Maier asserts that: “Many facts from antiquity rest on just one ancient source, while two or three sources in agreement generally render the fact unimpeachable.” The Jesus Seminar emphasizes items “attested in two or more independent sources.”

Several important examples might be provided. Of the five sources often recognized in the Gospel accounts, Jesus’ miracles are reported in all five, with some specific occurrences reported in more than one. Jesus’ crucial “Son of Man” sayings are also attested in all five Gospel sources. And the empty tomb is reported in at least three, if not four, of these Gospel sources. This helps to understand why these items are taken so seriously by contemporary critical scholars.

Timeline of New Testament sources

You can only use the data that pass these criteria when you are constructing historical hypotheses in a debate setting. But the passage of 1 Corinthians 15:3-7 is special, because it has the markings on an ancient creed. As Habermas explains, Paul received this creed within five years of the crucifixion. Paul verified this creed twice with eyewitnesses, Peter, John and James, in Galatians 1:11-24 and Galatians 2:1-10.

So, let’s set the date of Jesus’ death as being 30 AD. Then ask the question: what sources are closest to the event? We need to have multiple early sources in order to be able to surface minimal facts that can be used when debating skeptics and atheists. Here’s the timeline, using the absolute latest possible dates for the sources:

  • 30 A.D.: Jesus is crucified. (+0)
  • 31 A.D.: The early creed originates around this time
  • 35 A.D.: Paul receives the early creed from Peter, John and James in Jerusalem
  • 55 A.D.: 1 Corinthians (+25)
  • 70 A.D. Mark (+40)
  • 80 A.D. Matthew (+50)
  • 85 A.D. Luke (+55)
  • 95 A.D. John (+65)

My preferred dates on the gospels are at least 5 years ealier than the skeptical dates. So, your earliest source for minimal facts about the resurrection is 1 Corinthians 15:3-7. I explained before how to leverage the facts in 1 Cor 15, and other minimal facts, into a case for the resurrection.

Personal application

You really need to be able to talk to your friends and co-workers about the resurrection. That is our obligation as Christians. When you talk to non-Christians, you cannot use the entire Bible on faith. Your opponent is not going to allow you to use the entire text as a source because they don’t assume that it is inerrant. You need to argue from minimal facts that pass the standard historical criteria.

So, you need to learn how to explain how scholars extract the minimal facts from the Biblical sources. You need to list the criteria, explain why they are generally accepted, and then apply them. You need to know the dates and authors of the New Testament writings. You need to know which passages are considered to be minimal facts. And then you can make you case on those facts.

I think the most promising strategy is to argue from a supernatural creator and designer, using some recent scientific discoveries, and then go on from there to historical concerns once the existence of a deistic God has been firmly established.

Further study

First, listen to the 30-minute lecture delivered at California Polytechnic State University in 2008 by Gary Habermas, on 1 Corinthians 15:3-7. Then, check out N.T. Wright’s case for the resurrection. Then listen to this lecture delivered at California State University in 2005 by William Lane Craig, on arguing from the minimal facts.

And finally, you can check out some debates on the resurrection. I recommend the debate between William Lane Craig and Roy Hoover. But it is important to read the N.T. Wright’s case for the resurrection first! There is a cross-examination section in the debate, so if you’re into that, as I am, then get your fix here.
