William Lane Craig debates Lawrence Krauss in North Carolina: Does God Exist?

Would you like to hear a debate featuring the least intelligent atheist ever? Well, this is a good candidate.

The full transcript of the debate is here at the Reasonable Faith web site.

Audio of the William Lane Craig vs. Lawrence Krauss debate at North Carolina State University has now been posted at Apologetics 315. The people who recorded it did not do a good job, though.

And I also posted some background information on Craig’s arguments.

And now for one of my snarkiest summaries, which is fitting for Lawrence Krauss. A less snarky summary is at J.W. Wartick’s blog. And if you want to see a summary of a debate with a smart atheist, then here is the Craig-Millican debate summary.

William Lane Craig’s case

William Lane Craig made 5 arguments for the existence of God:

  • the contingency argument
  • theargument from the origin of the universe (kalam)
  • the argument from cosmic fine-tuning
  • the moral argument
  • the argument from the miracle of the resurrection

These arguments went unrefuted during the debate.

Lawrence Krauss’s case

Lawrence Krauss made the following arguments in his first speech:

  • Dr. Craig is a professional debater
  • Dr. Craig is not a scientist
  • Dr. Craig is a philosopher
  • Disproving God’s is a waste of my valuable time
  • Dr. Craig has the burden of proof to show evidence
  • My job is not to present any evidence
  • I think that “extraordinary claims require extraordinary evidence” is a nice slogan, but I have no evidence for it
  • I don’t like that God doesn’t appear on Youtube, therefore he doesn’t exist
  • I don’t like that God didn’t appear to humans until recently, therefore he doesn’t exist
  • I don’t like that the stars didn’t come together to spell “I am here”, therefore God doesn’t exist
  • Dr. Craig has to supply extraordinary evidence, because my favorite slogan says he has to
  • Dr. Craig talks about logic, but the universe is not logical
  • Dr. Craig doesn’t have any arguments, just things he doesn’t like
  • Dr. Craig doesn’t like infinity, and that’s why he believes in the Big Bang cosmology
  • Dr. Craig doesn’t like chance, and that’s why he believes in cosmic fine-tuning
  • Dr. Craig doesn’t like rape, and that’s why he believes in the ontological foundations of morality
  • If people believe in logic, then they can’t do science
  • The things that science discovers contradict the laws of logic
  • For example, Dr. Craig doesn’t like infinity, so he believes in the experimental measurements of the cosmic microwave background radiation
  • For example, Dr. Craig doesn’t like chance, so he believes in the fine-tuning of the gravitational constant for the formation of stable stars
  • Quantum mechanics shows that the universe is stranger than you think, therefore all of Craig’s arguments are false
  • My t-shirt says 2 + 2 = 5, therefore all of Craig’s arguments are false
  • Atheism may look ridiculous, but it’s true, and if you don’t like it, too bad – because the universe is very strange
  • Accidents happen all the time, so that explains the cosmic fine-tuning
  • We all have to convince ourselves of 10 impossible things before breakfast, and atheism is impossible, so you need to convince yourself of it
  • I don’t know about the Big Bang, so Dr. Craig cannot use the Big Bang to to prove the universe began to exist
  • I don’t know about the cosmic fine-tuning, so Dr. Craig cannot use the fine-tuning of cosmological constants to prove the fine-tuning
  • I don’t know anything about science, so Dr. Craig cannot use science in his arguments
  • Dr. Craig says that the universe is contingent because it began to exist 13.7 billion years ago based on the state-of-the-art scientific evidence for the Big Bang creation out of nothing from 1) red-shift of light from distant galaxies, 2) cosmic microwave background radiation, 3) helium-hydrogen abundances, 4) experimental confirmation of general relativity, 5) the second law of thermodynamics, 6) radioactive element abundances, etc., but how does he know that? I don’t know that
  • It’s fine not to know the answer to scientific questions like whether the universe began to exist, it’s more exciting
  • Thinking that the universe began to exist based on 6 pieces of scientific evidence is the “God-of-the-Gaps” fallacy, it’s intellectual laziness
  • But all kidding aside, the universe actually did begin to exist 13.72 billion years ago, exactly like Craig says in his argument
  • I could argue that God created the universe 4.5 seconds ago with all of us sitting believing that we heard Dr. Craig, and how could you prove me wrong? It’s not falsifiable
  • Universes can spontaneously appear out of nothing, and in fact they have to appear out of nothing
  • Nothing is unstable, and space and time can come into existence out of nothing, so that’s not a problem
  • Our universe could have appeared out of a multiverse, an unobservable, untestable multiverse that I have no way of observing or testing
  • The universe is not fine-tuned for life, and no scientist says so, especially not Martin Rees, the atheist Astronomer Royal, and every other scientist
  • What if God decided that rape was OK, would it be OK? God can change his moral nature arbitrarily, can’t he?

Here are the arguments in Krauss’ second speech:

  • We don’t understand the beginning of the universe
  • We don’t understand whether the universe had a cause
  • Steven Weinberg says that science makes it possible to be an atheist, so therefore the universe didn’t begin and didn’t have a cause
  • It’s just intellectual laziness to say that the universe came into being 13.7 billion years ago, and that things that come into being of nothing have a cause
  • Dr. Craig is an expert on nothing, ha ha ha!
  • There are multiple versions of nothing, there’s nothing, and then there is something, which is also nothing if I want it to be
  • There was no space, there was no time, and then the space create the empty space
  • I’m going to give Dr. Craig a break
  • At least in the nothing there were laws like F=ma, and those laws created the empty space, because descriptions of matter that does not even exist yet can create space out of nothing
  • Alan Guth and Alexander Vilenkin are good friends of mine and I talk to them all the time, unlike Dr. Craig
  • Alan Guth and Alexander Vilenkin don’t mention God in their scientific papers, therefore the universe didn’t begin and didn’t have a cause
  • Maybe there is a multiverse that cannot be observed or tested? And my unscientific speculations are a refutation of Craig’s scientific evidence for the fine-tuning
  • Dr. Craig just doesn’t like my speculations about the unobservable, untestable multiverse, and that’s why he believes in the Big Bang cosmology
  • And if you let me speculate about an unobservable, untestable multiverse, then maybe the inanimate invisible universes reproduce and compete for food and mutate like animals and then there is natural selection so that the finely-tuned universes survive and now we’re in one!
  • My cool animation of blue goo mutating proves that the multiverse is real! Empty space is not empty!
  • Darwinism, which is a theory about the origin of species, explains the cosmic fine-tuning that occurred at the moment of creation
  • The unobservable, untestable multiverse universes all have different laws, I believe
  • We don’t know what the right answer is, but we are willing to look at any possibility, as long as the possibilities we look at are not supernatural possibilities
  • The discovery of the origin of the universe could be an accident, I don’t know if the universe began to exist or not, maybe all the six scientific evidences are wrong because if I don’t like the evidence we have, so I’ll just wait for new evidence to overturn the evidence we have which I don’t like
  • Maybe there are other forms of life that are unobservable and untestable that are compatible with a universe that has no stable stars, no planets, no elements heavier than hydrogen, no hydrogen, no carbon, etc.

Here are the arguments in Krauss’ third speech:

  • Dr. Craig is stupid
  • Why should we even care about Dr. Craig’s arguments and evidence, we can just count the number of scientists who are atheists and decide whether God exists that way – I decided everything based on what my teachers told me to believe
  • I actually know general relativity, not like Dr. Craig who co-wrote a book on general relativity published by Oxford University Press
  • What quantum mechanics shows is that virtual particles come into being in a quantum vacuum, and then go out of existence almost immediately – and that is exactly like how a 13.7 billion year old universe came into being in a quantum vacuum, and we’re going to disappear very soon
  • Space and the laws of physics can be created, possibly, if you accept my speculations about an unobservable, untestable multiverse
  • I don’t like the God of the Old Testament, therefore he doesn’t exist
  • Groups of people can decide what they think is good and evil, like the Nazis and slave-owners did, and then that becomes good for them in that time and place, and that’s what I mean by morality
  • Here’s something I studied that wasn’t fine-tuned, therefore there is no fine-tuning of the universe
  • Not knowing things is really exciting! Dr. Craig is not really exciting because he knows things – phooey!

Here are the arguments in Krauss’ fourth speech:

  • If you will just grant me an observable, untestable multiverse, then there must be some universe where intelligent life exists
  • Infinite numbers of things exist everywhere in nature, you can see lots of infinite collections of things, like jelly beans and bumblebees and invisible pink unicorns
  • I don’t like the fine-tuning, but if my speculations about the multiverse are proven true, then I won’t have to learn to live with the fine-tuning
  • Inflation, the rapid expansion of the universe which occurs at some time after the the origin of the universe (t = 0), explains the absolute origin of time, space, matter and energy out of nothing that occurred at t = 0
  • Physical processes that develop subsequent to the creation of the universe at t > 0 can explain the fine-tuning of quantities that are set at t = 0
  • Morality is just a bunch of arbitrary conventions decided by groups of people in different times and places by an accidental process of biological and social evolution, but that practice over there by those people is objectively wrong!
  • 1 Cor 15:3-7, which most scholars, even atheists like James Crossley, admit is dated to within 3 years of the death of Jesus, is actually dated to 50 years after the death of Jesus
  • The historical case for the resurrection made by people like N.T. Wright in their multi-volume academic works is on par with the story of Mohammed ascending to Heaven on a horse

Does God’s omniscience conflict with human free will?

Here’s the setup for the question, from Come Reason ministries.

Excerpt:

Hello,

Christian doctrine holds that God is all knowing (1 John 3:20), and humans have free will (Deuteronomy 30:19 is my favorite example). however, at my favorite apologetics debate board, I have seen skeptics raise an objection to these points several times. the basic logic behind their arguments is this:

  1. A being with free will, given two options A and B, can freely choose between A and B.
  2. God is omniscient (all-knowing).
  3. God knows I will choose A.
  4. God cannot be wrong, since an omniscient being cannot have false knowledge.
  5. From 3 and 4, I will choose A and cannot choose B.
  6. From 1 and 5, omniscience and free will cannot co-exist.

I have read many counter-arguments from apologetics sites, but they were either too technical (I couldn’t understand them), or not satisfying. so, I was wondering what would your input be on this issue?

Thank you,

Justin

Ever heard that one? Here’s Lenny Eposito’s answer:

Hi Justin,

Thanks for writing. This is a great question as it shows how even those who appeal to logic can have biases that blind them. Let’s examine this argument and see if it follows logically.

Premises 1 and 2 in your outline above are the main premises to the argument and are not disputed. The Christian worldview argues that every human being is a free moral agent and is capable of making choices simply by exercising their will, not under compulsion or because of instinct. Also, it is a long held doctrine of Christianity that God is all-knowing. The Bible says that God knows “the end from the beginning (Isaiah 46:10).” For omniscience to be truly knowledgeable it must be correct knowledge, so premise number 4 is also granted.

However, point number 5 is where the logic falters. Those who argue in this manner make the mistake of thinking that because God possesses knowledge about a specific matter, then he has influenced it. That does not follow at all. Just because God can foresee which choice you will make, it does not mean you couldn’t still freely choose the other option.

Let me give you an example. I have a five year old son. If I were to leave a chocolate chip cookie on the table about a hour before dinner time and my son was to walk by and see it, I know that he would pick up the cookie and eat it. I did not force him to make that decision. In fact, I don’t even have to be in the room at all. I think I know my son well enough, though, to tell you that if I come back into the kitchen the cookie will be gone. His act was made completely free of my influence, but I knew what his actions would be.

In examining the argument, the assumption is made in premise 3 that because God knows I will choose A somehow denies me the choice of B. That is the premise that Christianity rejects. Omniscience and free will are not incompatible and it is a non-sequitor to claim otherwise.

Thank you Justin for this interesting question. I pray that you will continue to defend the gospel of our Lord and may He continue to bless you as you seek to grow in Him.

That’s a great answer and should work in ordinary conversations.

More technical

J.W. Wartick maps out the arguments more fully with symbolic logic here on his Always Have A Reason blog. But I’ll just excerpt the gist of it.

Excerpt:

It is necessarily true that if God knows x will happen, then x will happen. But then if one takes these terms, God knowing x will happen only means that x will happen, not that x will happen necessarily. Certainly, God’s foreknowledge of an event means that that event will happen, but it does not mean that the event could not have happened otherwise. If an event happens necessarily, that means the event could not have happened otherwise, but God’s foreknowledge of an event doesn’t somehow transfer necessity to the event, it only means that the event will happen. It could have been otherwise, in which case, God’s knowledge would have been different.

[…]Perhaps I could take an example. Let’s say that I’m going to go to classes tomorrow (and I do hope I will, I don’t like missing classes!). God knows in advance that I’m going to go to classes tomorrow. His knowledge of this event means that it will happen, but it doesn’t mean that I couldn’t choose to stay in and sleep for a while, or play my new copy of Final Fantasy XIII, or do something more useless with my time. If I chose to, say, play Final Fantasy XIII (a strong temptation!), then God simply would have known that I would play FFXIII. His knowledge does not determine the outcome, His knowledge is simply of the outcome.

If we choose A, God would foreknow A. If we choose B, God would foreknow B. His foreknowledge of our choices is contingent on our making free choices.

I had to learn symbolic logic and Bayes’ theorem in college for my computers science degrees, and it’s pretty useful for understanding these philosophers. Philosophy is a lot like computer science, at least for analytical philosophy.

UPDATE: Here’s another one from Sam Harper. I would click through just to read his funny author profile.

William Lane Craig lectures on the postmodern challenge to theism

In a lecture entitled “Are there Objective Truths About God?”, philosopher William Lane Craig responds to postmodern challenges to the idea of truth, and specifically to the idea that religion is about objective truth.

Here’s the link to a page containing the lecture audio. (H/T Be Thinking)

The MP3 file is here.

So what questions does Bill answer in the lecture?

What is a self-refuting statement?

The main concept in the lecture is self-refutation. A self-refuting sentence is a sentence that, if true, makes itself false or meaningless. For example, suppose someone said to you: “there are no sentences longer than 5 words” then that would be self-refuting since it falsifies itself. Bill argues that objections to the idea that there are objective truths about God are all self-refuting.

What is truth?

Craig holds that “truth” is a property of a proposition such that a proposition is true if it corresponds to the external world. For example, if I claim that there is a crocodile in your closet and we find a crocodile in your closet, then my statement was true. If there is no crocodile in your closet then my statement was false. The real objective world out there is what makes propositional claims true or false – these are not claims about an individual’s preferences, they are claims about the world. Bill is concerned with truth claims about God that are objective – whether there are propositions about God that are true regardless of what anyone thinks.

Are there objective truths about God?

Bill discusses 3 objections to the idea that there are objective truths about God. Each objection seeks to make religion subjective, (true for each person, like food preferences or clothing fashion).

Objection #1:The Challenge of Verificationism

The first challenge is that religious claims cannot be verified using the 5 senses, and therefore religious statements are objectively meaningless.

Consider the statement “Only propositions that can be verified with the 5 senses are meaningful”. That statement cannot be verified with the 5 senses. If the statement is true, it makes itself meaningless. It’s self-refuting.

Objection #2: The Challenge of Mystical Anti-Realism

The second challenge is that religious claims, and claims about God, are neither true nor false.

Consider the statement “Propositions about God cannot be true or false”. Craig asks – why should we accept that? Any reason given would have to assert something about God that is true or false, and those reasons would contradict the original statement. For example, “God is too great to be grasped by human categories of thought” is a proposition about God that the speaker thinks is true, which contradicts the original assertion.

Objection #3: The Challenge of Radical Pluralism

The third challenge is that each person invents an entire reality of their own, and that there is no mind-independent objective world shared by individuals.

Consider the statement “There is no objective reality shared by all individuals”. That statement is a statement that applies to all individuals, regardless of what they think.  It’s self-refuting.

Conclusion

Craig ends the lecture by arguing that it is OK for Christians to think that other people’s views are false. It does not follow that just because someone thinks other people’s views are wrong that they am going to mistreat other people. In fact, in Christianity it is objectively true that it is good for Christians to love their enemies. It is objectively true that all human beings have value, because human beings are made by God. So even if Christians disagree with others, they still treat them well, because they think that there are moral truths that they have to conform to.

My thoughts

Sometimes, non-Christians think that it is dangerous to hold beliefs too strongly. But I think what really matters is the content of the belief – some beliefs are false and some are true – you want to believe the true beliefs as strongly as you can, as long as the evidence warrants it. In Christianity, I am absolutely obligated to treat people with whom I disagree with respect and gentleness (1 Pet 3:15-16). The more convinced I am about that belief, the better my opponents will be treated. A stronger belief in Christianity means more tolerance for those who disagree.

Why do non-Christians get so offended when Christians claim to be right about there being only one way to be rightly related to God? Well, for many it’s because their worldview is a personal preference, and they feel uncomfortable having to defend it rationally and evidentially. Christianity is different – we are used to having to defend our truth claims using evidence, because that is the core of the religion, and the example of the founder and his closest followers.

For most people, religion is just their cultural preference – like cooking style, or favorite sport, or clothing style. That’s why they respond to your truth claims with name-calling like “you’re intolerant” and “you’re judgemental” and “you’re arrogant”. These are just shorthand ways of saying, “I’m offended that you think that what you believe is true and you think that what I believe is false”. They would never say that in a math classroom or a chemistry lab, where truth matters. But because they are coming to the discussion with the presupposition that religion is like clothing and diet preferences, they take everything personally instead of treating religion as something objective, just like any other area of knowledge.

This problem of being offended by truth claims is especially common with people who are raised to think that their religion is a racial, national or cultural identity. They haven’t thought anything through, or considered any alternatives, and they think that if you tell them they are wrong  on matters of fact that somehow this amounts to some sort of racism, intolerance or prejudice. You make factual claims, and they hear discrimination. But that’s not how Christians think of religion – we only care if it’s true or not – just like we care whether the claims of history or science are true or not. For many non-Christians, religion is not about truth at all but about personal preferences – and they cannot understand why Christians say that they have to go to Hell for having the wrong personal preferences. You have to tell them that religion is about truth, and that people displease God because they don’t know what is true, and they don’t want to know what is true. Then they understand why you are disagreeing with them and you can have a conversation about what is true.
