Here is my summary of the Craig-Rosenberg debate, which occurred on February 1st, 2013 at Purdue University.

The debaters

Below is the summary.

Dr. Craig’s opening speech:

The topic: What are the arguments that make belief in God reasonable or unreasonable?
First speech: arguments for reasonableness of belief in God
Second speech: respond to arguments against reasonableness of belief in God

Eight arguments:

  1. Contingency argument: God – a transcendent, personal being – is the explanation of why a contingent universe exists.
  2. Cosmological argument: God is the cause of the beginning of the universe, which is attested by physics and cosmology.
  3. Applicability of mathematics to nature: God is the best explanation for the applicability of mathematics to nature.
  4. Fine-tuning argument: God is the best explanation of the fine-tuning of the universe to permit life.
  5. Intentionality of conscious states: God is the best explanation of the intentionality of our mental states.
  6. The moral argument: God is the best explanation for the existence of objective moral values and duties.
  7. The resurrection of Jesus: God is the best explanation for the core of historical facts accepted by most ancient historians across the ideological spectrum.
  8. Religious experience: God is the best explanation of our immediate experience and knowledge of his existence.

Dr. Rosenberg’s opening speech

First argument: The fallacy of ad hominem

  • I don’t know whether to laugh or to cry
  • Dr. Craig has said all of that before in other debates
  • You didn’t need to come out on this cold night
  • Craig’s arguments have all been refuted
  • Dr. Craig just doesn’t listen
  • Dr. Craig is not interested in getting at the truth
  • Dr. Craig is just interested in scoring debate points
  • The adversarial system is the wrong approach to decide truth
  • Dr. Craig is very confident about his take of physics

Second argument: The fallacy of arguing from authority

  • 95% of members of the NAS are atheists
  • Therefore Dr. Craig cannot use science

Third argument: Effects don’t require causes

  • I am going to pretend that Craig said that “every effect requires a cause”
  • Quantum mechanics shows that some effects occur without causes
  • A particle of uranium (which is not nothing, it is something) decays without a cause
  • This uncaused effect is the same as the universe coming into being out of nothing uncaused
  • Therefore the principle of sufficient reason is false

Fourth argument: Silicon-based life and the multiverse

  • If these constants had been different, maybe we would have other kinds of intelligent life, like silicon-based life
  • Carbon-based life is not the only kind of life, maybe you can have other kinds of life, none of which have been observed
  • There could be different kinds of life in other areas of the universe that we can’t see
  • There are things we can’t see that disprove the current physics that we can see
  • Quantum foam is evidence that a multiverse exists
  • The multiverse would solve the problem of fine-tuning

Fifth argument: The Euthyphro dilemma

  • The moral argument is refuted by Euthyphro dilemma
  • Dr. Craig is such a moron that he has never heard of the Euthyphro dilemma ever before
  • This is found in the first and simplest of Plato’s dialogs
  • Why is Dr. Craig so stupid that he has not read this simple dialog ever before?
  • Evolution explains why humans evolve arbitrary customs and conventions that vary by time and place
  • Alternative moral theories: utilitarianism, social contract, etc. that don’t require God

Sixth argument: Mormonism undermines Dr. Craig’s three minimal facts about Jesus

  • Why is Dr. Craig so stupid and ignorant to persist in pushing such an ignorant, stupid argument?
  • Mormonism is a silly religion that is not historically well founded
  • Therefore, Jesus was not buried
  • Islam is a silly religion that is not historically grounded
  • Therefore, the tomb was not found empty
  • Scientology is a silly religion that is not historically grounded
  • Therefore, the eyewitnesses didn’t have post-mortem appearances
  • Eyewitness testimony is unreliable in some cases
  • Therefore, eyewitness testimony was unreliable in this case
  • Apparitions of Mary are bizarre
  • Therefore, the majority of historians are wrong to think that the disciples saw post-mortem appearances

Seventh argument: Deductive problem of evil

  • Evil and suffering are logically incompatible with an all good, all powerful God

Eight argument: God is not just to allow evil and suffering

  • God cannot make the evils of this life right in the afterlife

Dr. Craig’s first rebuttal

Dr. Rosenberg sketched the deductive argument from evil.

Dr. Rosenberg presupposes naturalism. Naturalism is a false theory of knowledge:

1. It’s too restrictive: There are truths that cannot be proved by natural science.
2. It’s self-refuting: no scientific proof for naturalism exists.

That’s why epistemological naturalism is considered false by most philosophers of science.

But more importantly than that: Epistemological naturalism does not imply metaphysical naturalism. (E.g. – W. Quine)

Dr. Rosenberg has to present arguments in favor of (metaphysical) naturalism, not just assume that (metaphysical) naturalism is true.

Dr. Craig presented eight arguments against metaphysical naturalism taken from Rosenberg’s own book:

1. The argument from the intentionality (aboutness) of mental states implies non-physical minds (dualism), which is incompatible with naturalism
2. The existence of meaning in language is incompatible with naturalism, Rosenberg even says that all the sentences in his own book are meaningless
3. The existence of truth is incompatible with naturalism
4. The argument from moral praise and blame is incompatible with naturalism
5. Libertarian freedom (free will) is incompatible with naturalism
6. Purpose is incompatible with naturalism
7. The enduring concept of self is incompatible with naturalism
8. The experience of first-person subjectivity (“I”) is incompatible with naturalism

Metaphysical naturalism is false: it is irrational and it contradicts our experience of ourselves.

And epistemological naturalism is compatible with theism.

Rebutting Dr. Rosenberg’s responses:

1. Contingency: no response

2. Cosmological: he mis-states the first premise to say every effect… when it is whatever begins to exist…, the origin of the universe was not from a vacuum, virtual particles come from a vacuum not nothing, there are interpretations of QM that are compatible with determinism. Rosenberg has to believe that the entire universe popped into being from non-being.

3. Mathematics: no response

4. Fine-tuning: the multiverse is refuted by empirical observations of the universe. Without fine-tuning, it’s not that we still have silicon to make life out of. It’s that we lose basic minimal things like chemical diversity, matter, stars, planets, etc. No life of any kind, not just no carbon-based life.

5. Intentionality: no response.

6. Moral argument: the answer to the dilemma is that you split the dilemma: God is the standard of good, and the commands flow from his unchanging moral nature. The commands are not arbitrary, and the standard is not external to God. Dr. Rosenberg is a nihilist and he cannot ground good and evil on his nihilistic view.

7. Resurrection: The Gospels are early eyewitness testimony. Mormonism and Islam have nothing to do with the minimal set of historical facts about Jesus agreed to by the majority of ancient historians across the ideological spectrum, general statements against eyewitnesses do not refute the specific eyewitness testimony in this case.

8. Religious experience: No response.

Dr. Rosenberg’s first rebuttal

I wrote a book and you should buy it, because it got me invited to this debate. Let me repeat the title a few times for you. Please buy it.

Dr. Craig is right, there are multiple interpretations of QM, not just the one I presented, including deterministic ones.

All the disturbing implications of naturalism that Dr. Craig stated follow from metaphysical naturalism, and metaphysical naturalism is true. (Note: he equates science with metaphysical naturalism)

Science proves that metaphysical naturalism is true, but I won’t say what specific scientific tests prove my philosophical assumption of metaphysical naturalism.

I’ll pretend that the Big Bang (science) doesn’t disprove naturalism, like Dr. Craig said. Again. (covers ears) La la la, there is no Big Bang.

We didn’t come here to debate epistemological naturalism and metaphysical naturalism.

Let me explain the problem of intentionality since I’m so smart and no one knows what it means.

There are many answers to this problem of intentionality.

My answer is that most scientists are naturalists, therefore naturalism is true, regardless of the argument from intentionality of mental states.

That’s how I would respond to one of the eight problems with naturalism that Dr. Craig raised. I won’t answer the other seven problems.

It is an argument from ignorance to argue that the applicability of mathematics to the universe requires a designer, because there are non-Euclidean geometries. Craig’s argument, which he gets from people like respected physicists like Eugene Wigner, is bizarre. It is bizarre, therefore I refute Eugene Wigner and all the other scholars who make that argument. It is bizarre! Bizarre!

Deductive problem of evil: there is no response to this argument, certainly not Alvin Plantinga’s free will defense. The deductive argument from evil has not been entirely abandoned at all! It’s not like arch-atheist J.L. Mackie himself admits that the deductive problem of evil doesn’t lead to a logical inconsistency between evil and God.

Dr. Craig has to tell me why God allows evil or God doesn’t exist.

It is offensive that Dr. Craig cannot tell me why God allows every evil and suffering that occurs.

He literally said this: “I will become a Christian if Dr. Craig can tell me why God allowed EVERY EVIL THAT OCCURRED IN THE LAST 3.5 BILLION YEARS”

Dr. Craig’s second rebuttal

We are not in a position to know why God allows specific instances of evil and suffering.

God cannot force people to freely do anything – freedom is not compatible with determinism. Freedom is a good, but freedom opens up the possibility of moral evil. You cannot have the good of free will without allowing people to choose to do morally evil things.

God can permit evil and suffering in order to bring more people into a relationship with him.

The atheist has to show that God could allow less evil and achieve more knowledge of God in order to say there is too much evil.

The purpose of life is not happiness, but knowledge of God.

Dr. Craig quotes agnostic Paul Draper (Purdue) and Peter Van Inwagen (Notre Dame) to state that the deductive problem of evil is dead because of free will and morally sufficient reasons for permitting evil.

1. Contingency: no response.

2. Cosmological: QM does not apply, because the universe came from nothing, not a vacuum, and QM only works in a vacuum.

3. Mathematics: He mentions alternatives like non-Euclidean geometry, but we have to explain the structure of THIS universe.

4. Fine-tuning: ???

5. Intentional states: intentional mental states proves that minds exist, which fits with theism better than it fits with atheism.

6. Moral argument: You need God to ground morality, and Dr. Rosenberg believes in morality. He needs God to ground objective moral values and duties.

7. Historical argument: He has to respond to the minimal facts supported by the consensus of ancient historians across the ideological spectrum.

8. The problems of naturalism: He says that you can’t have science without naturalism, but you can have science with EPISTEMOLOGICAL NATURALISM, and theists accept science and methodological naturalism. We don’t accept METAPHYSCIAL NATURALISM because of the eight problems Craig presented, like intentionality, first-person, persistence of self, etc. You can believe in both science and theism, by embracing epistemological naturalism, while rejecting methaphysical naturalism.

Dr. Rosenberg’s second rebuttal

Dr. Craig hasn’t answered many of my points, I won’t say which ones though.

Debates don’t work as a way of deciding what’s true, so we should overturn the entire criminal justice system.

The principle of sufficient reason is false because it is disconfirmed by quantum mechanics. And quantum mechanics (vacuum and virtual particles that exist for a short time) is similar to the origin of the universe (nothing and entire universe and 14 billion years).

We know that alpha particles come into being without cause all the time from a quantum vacuum for a tiny sub-second duration before going out of existence, so we can say that the entire physical universe came into being for 14 billion years from absolute nothing which is not a quantum vacuum.

Peter Van Inwagen is the best metaphysician working today, and he says that my deductive argument from evil is not decisive, it’s not a successful argument. (Why is he undermining his own problem of evil argument????!)

Dr. Craig invoked Plantinga’s free will defense to the deductive POE. Freedom allows us to do evil. God could have given us free will without evil and suffering. I won’t show how, but I’ll just assert it, because debates are such a bad forum for supplying evidence for my speculative assertions.

If you answer the question 3 + 5 as being 8, then you don’t have free will – you are biologically determined if you answer 8, because everyone answers 8, and that means everyone is biologically determined with no free will.

Why can’t God give us free will and then prevent us from making a free choice?

No scholars date the gospels earlier than 60-70 AD, especially not atheists like James Crossley who dates Mark to 40 AD. Therefore Jesus’ burial isn’t historical, like the majority of scholars across the broad spectrum of scholarship agree it is.

The original New Testament documents were written in Aramaic.

All New Testament scholars are orthodox Christians, like atheist Robert Funk for example.

Dr. Craig’s concluding speech

In order to sustain the deductive argument from evil, Dr. Rosenberg must show that God could create a world of free creatures with less evil.

Principle of Sufficient Reason: not using the general principle of sufficient reason, but a more modest version of this states that contingent things should have an explanation for their existence. And we know that the universe is a contingent.

The New Testament was not written in Aramaic, they were written in Greek. Dr. Rosenberg is wrong there too.

(Dr. Craig spends the rest of his concluding speech giving his testimony and urging people to investigate the New testament).

Dr. Rosenberg’s concluding speech

Some long-dead French guy named Laplace said that he has no need of that (God) hypothesis. He did not know about any of Dr. Craig’s arguments made in this debate tonight when he said that, though.

There is no need to explain how the universe began or how the universe is finely-tuned if you just assume metaphysical naturalism on faith.

The Easter Bunny, therefore atheism.

Most scientists are atheists, therefore atheism.

You can do a lot of science without God, just don’t look at the origin of the universe, the fine-tuning of the universe, or the other parts of science that Craig mentioned, as well as the origin of life, the Cambrian explosion, the habitability argument, and so on.

You can be a Christian, but good Christians should not use arguments and evidence.

Good Christians should be irrational and ignorant. Bad Christians look for arguments and evidence from science and history.

Good Christians should embrace the absurd. Bad Christians want to search for truth and use logic and evidence.

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

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

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 NOT 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.

By the way, if you are looking for a good book on the cosmic fine-tuning, especially for evangelism and debating with atheists, you really need to get a copy of “A Fortunate Universe“. Although it is from one of the most prestigious academic presses, it is pretty funny to read, and the main points are made clearly, even if you don’t understand the science. Two astrophysicists wrote it – one who believes that God is the best explanation of the fine-tuning, and one who doesn’t. I really think that Christians need to get used to the idea that evangelism can be pretty easy, so long as you are arguing from peer-reviewed facts. When you get a good book on evidence for God that is not in dispute, then you are invincible. Everybody ought to believe in God in a universe with this much overt scientific evidence spilling out everywhere. Whether this Creator and Designer is the God of the Bible, who visited us as Jesus of Nazareth, takes more work to establish. Working through the emotional objections people have to God, and coaching them to take on the difficulties of living out a authentic Christian life (very unpopular!), is even harder.

Why do some Christians say “all sins are equally bad” and “everyone is equally guilty”?

Young women very supportive of premarital sex
Young women very supportive of premarital sex

We were having a discussion about whether the Bible teaches that sex before marriage is morally wrong, and someone said “impure thoughts counts as adultery… there isn’t a virgin among us”.

Regarding her point that lust is equal to adultery, and so no one is really a virgin, here’s Ligonier Ministries:

In demonstrating that the seventh commandment was given also to prohibit lust, Jesus is not somehow saying that an unconsummated lustful intent is sinful to the same degree as an actual extramarital affair (though both sins merit punishment). The latter is a more blatant violation of the statute against adultery, and it has greater consequences in the form of divorce and the loss of one’s reputation as a trustworthy person.

Any serious student of the Bible is aware of Jesus’ tendency to exaggerate / use hyperbole.

Also, 1 Corinthians 7 says that wives are not supposed to make a habit of denying their husbands sex. Sex withholding is more of an epidemic today than pornography, and it should also be on the adultery spectrum. It isn’t as bad as adultery, but it definitely breaks the marital covenant.

So why would someone say that lust is the same as adultery, and that there is no such thing as a virgin?

Dr. Michael Krueger recently blogged about this “all sins are equal” view.

Krueger says this:

First, to say all sins are the same is to confuse the effect of sin with the heinousness of sin. While all sins are equal in their effect (they separate us from God), they are not all equally heinous.

Second, the Bible differentiates between sins. Some sins are more severe in terms of impact (1 Cor 6:18), in terms of culpability (Rom 1:21-32), and in terms of the judgment warranted (2 Pet 2:17; Mark 9:42; James 3:1).

Krueger explains the motivation behind the slogans:

[S]ome Christians… use this phrase as way to “flatten out” all sins so that they are not distinguishable from each other. Or, to put it another way, this phrase is used to portray all human beings as precisely the same. If all sins are equal, and all people sin, then no one is more holy than anyone else.

In a world fascinated with “equality,” this usage of the phrase is particularly attractive to folks. It allows everyone to be lumped together into a single undifferentiated mass.

Such a move is also useful as a way to prevent particular behaviors from being condemned. If all sins are equal, and everyone is a sinner, then you are not allowed to highlight any particular sin (or sinner).

Needless to say, this usage of the phrase has featured largely in the recent cultural debates over issues like homosexuality. Yes, homosexuality is a sin, some Christians reluctantly concede. But, they argue, all sins are equal in God’s sight and therefore it is no different than anything else. Therefore, Christians ought to stop talking about homosexuality unless they are also willing to talk about impatience, anger, gluttony, and so on.

Krueger also posted this fascinating follow up post, where he looks at how the phrase is being used by people on Twitter.

Look at these tweets:

  • All sins are equal. People tend to forget that. There is no bigger or smaller sin. Being gay and lying, very equal.

  • all sins are equal in God’s eyes. whatever you’re doing, is no better than what someone else is doing.

  • If you have sex before marriage please don’t come on social media preaching about the wrongs of homosexuality. All sins are equal

  • Need people to realize that all sins are equal… don’t try to look down on me or question my faith just cuz you sin differently than I do.

  • Don’t understand why you’re so quick to judge me, when all sins are equal. So much for family..

  • if you think being gay is a sin, let me ask you something, have you not done anything wrong in your life? all sins are equal. we’re sinners

  • Nope no difference at all. All sins are equal no matter what you’re running for. The bible says do not judge lest ye be judged

  • A huge problem I have with religion is the notion that all sins are equal. Like pre-martial sex and murder are the same amount t of bad.

  • people do bad things because they believe that all sins are equal and ~god~ loves y’all equally so he’s going to forgive you naman ha ha ha

  • It a sin to condemn another sinner and their actions. All sins are equal. So what makes you better than the person you’re condemning?

  • I think so b/c having sex before marriage doesn’t make you less of a women then if you waited until marriage.. all sins are equal soo

  • friendly reminder, all sins are equal in gods eyes so you’re not better than I am in any way. please worry about your own sins before mine.

  • People don’t like when I suggest abortion as an option. This is a free country and all sins are equal so mind your business!!!

  • What I do is no worse than wat you do… all sins are equal no matter what it is… a sin is a sin

  • to god all sins are equal so you have no right to compare your sins to someone else’s bc in the end it doesn’t matter

The first thing that I noticed is that premarital sex and homosexuality are the most popular sins. I would think that divorce and abortion would be up there in the rankings, as well.

People want to be free to follow their hearts when seeking pleasure, then quote the Bible (badly) afterwards, to attack anyone who says that anything they’ve done is morally wrong. They would rather escape the judgment of their peers than admit fault and try to fix the mistake, and do better next time. And they would rather tell people who are hurting themselves by breaking the rules that there are no rules. It makes them feel good to “not judge” – they feel as if they are being kind. Their compassion looks good to non-Christians. And they’re promoting moral relativism which, when it becomes widespread, prevents anyone from judging them.

It’s so bad now, that the people who have morals and who make moral judgments are seen as the real bad people. The immoral people are on the offense, and even trying to ban people from being able to disagree with them.
