Here’s the article from Harper’s magazine. The MIT physicist says that the fine-tuning is real, and is best explained by positing the existence of an infinite number of universes that are not fine-tuned – the so-called multiverse.
Excerpt:
While challenging the Platonic dream of theoretical physicists, the multiverse idea does explain one aspect of our universe that has unsettled some scientists for years: according to various calculations, if the values of some of the fundamental parameters of our universe were a little larger or a little smaller, life could not have arisen. For example, if the nuclear force were a few percentage points stronger than it actually is, then all the hydrogen atoms in the infant universe would have fused with other hydrogen atoms to make helium, and there would be no hydrogen left. No hydrogen means no water. Although we are far from certain about what conditions are necessary for life, most biologists believe that water is necessary. On the other hand, if the nuclear force were substantially weaker than what it actually is, then the complex atoms needed for biology could not hold together. As another example, if the relationship between the strengths of the gravitational force and the electromagnetic force were not close to what it is, then the cosmos would not harbor any stars that explode and spew out life-supporting chemical elements into space or any other stars that form planets. Both kinds of stars are required for the emergence of life. The strengths of the basic forces and certain other fundamental parameters in our universe appear to be “fine-tuned” to allow the existence of life. The recognition of this finetuning led British physicist Brandon Carter to articulate what he called the anthropic principle, which states that the universe must have the parameters it does because we are here to observe it. Actually, the word anthropic, from the Greek for “man,” is a misnomer: if these fundamental parameters were much different from what they are, it is not only human beings who would not exist. No life of any kind would exist.
If such conclusions are correct, the great question, of course, is why these fundamental parameters happen to lie within the range needed for life. Does the universe care about life? Intelligent design is one answer. Indeed, a fair number of theologians, philosophers, and even some scientists have used fine-tuning and the anthropic principle as evidence of the existence of God. For example, at the 2011 Christian Scholars’ Conference at Pepperdine University, Francis Collins, a leading geneticist and director of the National Institutes of Health, said, “To get our universe, with all of its potential for complexities or any kind of potential for any kind of life-form, everything has to be precisely defined on this knife edge of improbability…. [Y]ou have to see the hands of a creator who set the parameters to be just so because the creator was interested in something a little more complicated than random particles.”
Intelligent design, however, is an answer to fine-tuning that does not appeal to most scientists. The multiverse offers another explanation. If there are countless different universes with different properties—for example, some with nuclear forces much stronger than in our universe and some with nuclear forces much weaker—then some of those universes will allow the emergence of life and some will not. Some of those universes will be dead, lifeless hulks of matter and energy, and others will permit the emergence of cells, plants and animals, minds. From the huge range of possible universes predicted by the theories, the fraction of universes with life is undoubtedly small. But that doesn’t matter. We live in one of the universes that permits life because otherwise we wouldn’t be here to ask the question.
I thought I was going to have to go outside this article to refute the multiverse, but Lightman is honest enough to refute it himself:
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. The problem is that the multiverse generator itself would require fine-tuning, and, as Lightman indicates, we have no independent experimental evidence for the existence of the multiverse. 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 from the cosmological argument, the moral argument, and so on.
We need to be frank about atheists and their objections to the progress of science. Within the last 100 years, we have discovered that the physical universe came into being out of nothing 15 billion years ago, and we have discovered that this one universe is fine-tuned for intelligent life. Atheists are 100 years out of date, and they are hoping that all of this 100 years of progress will be overturned, so that they can go back to their comfortable belief that the universe is eternal and that the parameters of this universe are undesigned.
While I was listening the Dennis Prager show, an atheist caller called Prager and asserted that atheism was true because he has a happy life as an atheist. And I think that’s what atheism is. They believe that God, if he exists, should have the goal of making them happy. And if they are already happy, then why would they care about whether there is a God out there who might ask them to do things (like not kill babies) which might make them unhappy?
Atheists don’t care about science as something that determines what they should or should not believe. If science proves that they are accountable to God, then they invent speculations and hope in those speculations against the science – as with the multiverse or the aliens seeding the Earth with life or the unobservable, untestable hyper-universe that spawned this universe.
To see these arguments examined in a debate with a famous atheist, simply watch the debate between William Lane Craig and Christopher Hitchens, and judge which debater is willing to form his beliefs on scientific progress, and which debater is forming his beliefs against the science we have today, and hoping that the good science we have today based on experiments will be overturned by speculative theories at some point in the future. When you watch that debate, it becomes very clear that Christian theists are interested in conforming their beliefs to science, and atheists are very interested in speculating against what science has shown in order to promote their own happiness. Whatever standard of morality they invent for themselves has to be self-made, so that they can satisfy it merely by doing whatever they feel like doing. And if science shows that the universe doesn’t conform to invented morality, because it is designed, then atheists just say “so much the worse for science”.
Just to re-cap, we’ve had peer-reviewed scientific publications in the last month that have made the illusion of naturalism even less likely, in the areas of the fossil record and the origin of life. And we now have the Borde-Vilenkin-Guth theorem, showing that any cosmology that features an expanding universe will have a beginning. The progress of science marches on against atheism, in virtually every area, and all we see from the likes of Richard Dawkins is the complete refusal to engage in debates with theists about the evidence. So who is anti-science now?
From Justin Brierley and the Reasonable Faith UK Tour:
The debate was held at the University of Birmingham, England in 2011. I would put this debate in the top 3 Craig debates ever, along with his debates against Austin Dacey and Walter Sinnott-Armstrong.
My summary of the Craig-Millican is below. This debate is really meant for advanced students, but if you read my post “What you need to know about the BVG Theorem” before watching the debate, it should help you to follow along.
Dr. Craig’s opening speech:
There are good reasons to believe that God exists.
There are no good reasons to believe that God does not exist.
A1) The origin of the universe
The universe began to exist
If the universe began to exist, then the universe has a transcendent cause.
The universe has a transcendent cause.
The origin of the universe is confirmed by philosophical arguments and scientific evidence.
There cannot be an actual infinite number of past events, because mathematical operations like subtraction and division cannot be applied to actual infinities.
The Borde-Guth-Vilenkin (BGV) proof shows that every universe that expands must have a space-time boundary in the past. That means that no expanding universe, no matter what the model, cannot be eternal into the past.
Even speculative alternative cosmologies do not escape the need for a beginning.
The cause of the universe must be transcendent and supernatural. It must be uncaused, because there cannot be an infinite regress of causes. It must be eternal, because it created time. It must be non-physical, because it created space. There are only two possibilities for such a cause. It could be an abstract object or an agent. Abstract objects cannot cause effects. Therefore, the cause is an agent.
A2) The fine-tuning of the universe
The fine-tuning of the universe is either due to law, chance or design.
It is not due to law or chance.
Therefore, it is due to design.
The progress of science has revealed that the Big Bang was fine-tuned to allow for the existence of intelligent life.
Type 1: Constants like the gravitational constant are finely-tuned, and are not dependent on the laws of physics.
Type 2: Quantities like the amount of entropy in the universe, are not dependent on the laws of physics.
The range of life-permitting values is incredibly small compared to the possible values of the constants and quantities. (Like having a lottery with a million black balls and one white ball, and you pick the white ball. Even though each individual ball has the same tiny chance of being picked, but the odds are overwhelming that the whichever ball you pick will be black, and not white).
Not only are the numbers not due to laws, but they are not due to chance either. It’s not just that the settings are unlikely, it’s that they are unlikely and they conform to an independent pattern – namely, the ability to support complex life.
A3) The moral argument
If God does not exist, then objective moral values do not exist.
Objective morality does exist.
Therefore, God exists.
Objective moral values are values that exist independently of whether any humans believe them or not.
Michael Ruse, an atheist philosopher agrees that if God does not exist, then there is only a “herd morality” that is determined by biological evolution and social evolution. There no objective moral standard, just different customs and conventions that vary by time and place. Anyone who acts against the herd morality is merely being unfashionable and unconventional. On the atheistic view, there is nothing objective and binding about this evolved “herd morality”. However, people do experience objective moral values, and these cannot be grounded on atheism.
Furthermore, God must exist in order to argue that there is evil in the world. In order to be able to make a distinction between good and evil that is objective, there has to be a God to determine a standard of good and evil that is binding regardless of the varying customs and conventions of different people groups. Even when a person argues against God’s existence by pointing to the “evil” in the world, they must assume objective moral values, and a God who grounds those objective moral values.
A4) The resurrection of Jesus.
There are certain minimal facts that are admitted by the majority of historians, across the ideological spectrum: the empty tomb, the appearances and the early belief in the resurrection.
Naturalistic attempts to explain these minimal facts fail.
The best explanation of these facts is that Jesus rose from the dead.
A5) Religious experience
People can know that God exists through experience. In the absence of defeaters for these experiences, these experiences constitute evidence for God’s existence.
Dr. Millican’s opening speech:
Dr. Craig has the burden of proof because he claims that God exists.
The Christian God hypothesis:
An omnipotent, omniscient, omnibenevolent God created the universe.
This God cares about humans.
This God has acted in history though the life of Jesus of Nazareth.
This is a factual claim, and we are discussing the evidence for whether these claims are true or false. We are not interested in religious practice, or the consolation of religious belief, nor any other religions.
A1) Religious pluralism and epistemology
Human beings are purpose-finding creatures – we are prone to prefer explanations that involve purpose.
Human beings are pattern-finding animals – we tend to find designs in states of affairs.
Human beings have an interest in maintaining religious hierarchies because of the power it gives them.
Religious beliefs are not determined by rational considerations, but are determined by geographic location.
The same non-scientific method of generating religious beliefs (purpose-finding, pattern-finding, geographic location, parental teaching, charismatic speakers, praise songs and worship, religious education, ancient holy books) is being used in several religions, and it leads to different, contradictory truth claims. So at least some of those conflicting claims are false. And if the method is generating some false claims, then it’s not a good method, and it undermines all the religions that use those methods.
A2) Absence of evidence is evidence of absence
There is no scientific evidence for God.
A3) Mental processes depend on physical systems
There is no scientific evidence for a disembodied intelligence.
Our universal human experience is that intelligence and mental operations require a physical brain.
The quality of our thinking depends on physical conditions, like being tired or on drugs.
But Christian theists believe that mental processes can exist independently of an underlying physical reality, unimpaired by the death of the physical body and the brain.
R.A1) The origin of the universe
1. There is no evidence that whatever begins to exist requires a cause. All the evidence we have of things beginning to exist are when something is created from rearrangements of other things that already existed.
The closest analog we have to something coming into being from nothing is quantum particles coming into being from nothing, and that causation is random.
There is no evidence that thoughts can bring about physical effects, and Bill is arguing for a mental cause to the origin of the universe.
Even if things that begin to exist IN the universe have causes, it doesn’t hold for the universe as a whole. Bill is committing the fallacy of composition.
Time begins with the universe, but our experience of causation is that it is a temporal process. So if there is no time “prior to” the universe’s beginning, then how can there be a cause to the universe?
It’s possible that there could be something outside our universe that is eternal.
It’s also possible that the Big Bang could be wrong, and this universe could oscillate eternally and not require a beginning.
2. There are cosmological theories that avoid the beginning of the universe by positing a prior period of contraction prior to the Big Bang.
The beginning of this universe depends on general relativity, and that theory breaks down at the level of quantum mechanics.
3. There is no evidence that minds can exist without an underlying physical system. So even if there is a cause of the universe, then it is neither an abstract object nor a mind. It would have to be something else, and not something we are familiar with – we are just not in a position to speculate of what it could be.
R.A3) The moral argument
Atheists do believe in a standard of morality that is not based on what groups of humans believe.
Utilitarians think there is a standard of moral values that is objective, because the measure of human happiness (for the greatest number) is objective, even if people are mistaken about what promotes that happiness.
Kantians have a rational process for determining which moral imperatives should be universalized.
Humeans have a system that is rooted in natural human sentiment.
Dr. Craig’s first rebuttal:
I do not have the only burden of proof. The topic is “Does God Exist?”. If Dr. Millican answers “no” then he has a burden of proof, otherwise we are left with agnosticism.
R.A1) Religious pluralism and epistemology
First, there is no single common method of adopting a religion.
Second, MY method this evening is logic and evidence and personal experience – which is the same as his method. So his comments about how people in different religions adopt their religion through parents, church, singing, etc. have no bearing on the arguments I will be making.
R.A2) Absence of evidence is evidence of absence
Absence of evidence is only evidence of absence if we can reasonably expect that there should be some evidence that is not present. He would have to show that there should be more evidence for God’s existence that the 5 arguments that I already presented – something that we should expect to see that we don’t see.
R.A3) Mental processes depend on physical systems
No response by Dr. Craig. (but see below)
A1) The origin of the universe
1. He says that there are speculative cosmologies like the multiverse that escape the need for a beginning, but that’s false, the BGV proof applies to them, and they do need a beginning.
He says that you can escape BGV by positing a contraction prior to the expansion. However Vilenkin says that any contraction phase is unstable and would introduce additional singularities that would hamper any later expansion phase.
He says that we need a theory of quantum gravity in order to describe the early universe. But Vilenkin says that the BGV proof is independent of gravity as defined by general relativity.
He did not respond to the philosophical arguments for a beginning of the universe.
2. He says that we don’t have experience of things coming into being except from material causes. However, it would be even more difficult to explain the universe coming into being on atheism since you can’t appeal to a material cause nor to an efficient cause. Even Hume recognizes that things can’t pop into being without causes.
He talks about how in quantum physics virtual particles appear out of nothing. But that’s false, because the quantum vacuum in which virtual particles appear is not nothing, it is a sea of subatomic particles and energy. Quantum physics is not an exception to the idea that things that come into being require a cause.
He mentions the fallacy of composition. But I am not saying that everything in the universe has a cause, therefore the universe as a whole has a cause. I am saying that non-being has no capacity to bring something into being. Non-Being doesn’t even have the potential to bring something into being.
3. He says that there are no unembodied minds, so the cause of the universe can’t be an unembodied mind. But the argument concludes that there is a non-material cause, and it can’t be an abstract object, so it would have to be a mind.
In addition, we ourselves are unembodied minds. This is because physical objects cannot have the properties that minds have, like the property of having feelings.
Material conceptions of mind don’t explain identity over time.
Material conceptions of mind don’t explain free will.
Material conceptions of mind don’t explain intentional states (thinking about something).
Material conceptions of mind don’t explain mental causation.
The best explanation for our own first person experience of the mental realm is a substance dualism. We are non-material minds, and we can cause effects in the physical world. And God does the same thing. He is a mind, and he causes physical effects.
A2) He gave no response.
A3) He says that there are atheistic theories of morality that don’t depend on the opinions of groups. But these theories all depend on the idea that human beings have instrinsic value – that they are the sorts of things to which moral considerations apply. Naturalism cannot ground this moral value – human beings are no more valuable any other animal.
Also, there are no objective moral obligations in naturalist systems of morality, because there is no one in authority to command them. Moral prescriptions require moral prescribers.
A4) He gave no response.
A5) He gave no response.
Dr. Millican’s first rebuttal:
R.A2) The fine-tuning argument
We have to be careful not to judge what counts as finely-tuned through our intuitions.
We have to be careful about reasoning for a sample size of this one observable universe.
We don’t really know about the full range of possibilities for these constants and quantities.
There might be other universes that we can’t observe that aren’t fine-tuned, and we just happen to be in the one that is fine-tuned.
The fine-tuning might be solved by future discoveries, like the inflationary cosmology removed some of the fine-tuning.
There might be a multiverse that we don’t have evidence for right now.
We need to be careful about using science to prove God because science might change in the future.
The universe is very big and mysterious.
This argument doesn’t prove that God is good. He could be evil = anti-God.
God created the universe inefficiently if his goal was to produce life.
God created the universe too big.
God created the universe too old.
God created too many galaxies and stars that are not hospitable to life.
If the universe were fine-tuned for life, then there should be more aliens.
If the universe were fine-tuned for life, then there are probably lots of alien civilizations. But then Jesus would have to appear to all of the aliens too.
R.A1) The origin of the universe
2. It’s not a big deal that you can get multiple solutions to equations involving subtraction of actual infinities. For example, the equation 0 x y = 0 has many solutions for y, but that doesn’t mean that multiplication doesn’t work in the real world.
A2) Absence of evidence is evidence of absence
I would expect that there would be more evidence than there is.
R.A1) The origin of the universe
2. The BVG proof might be overturned by future scientific discoveries. We have no reason to be confident in current physics.
I agree that the quantum vacuum is something and not nothing, but it’s similar to nothing.
We don’t have any reason to believe that things that come into being require causes – except for our universal experience that this is always the case.
3. As to the cause of the universe coming into being, you said that it could only be an abstract object or a mind, and it can’t be an abstract object because they don’t cause effects, so it must be a mind. But there are all sorts of things we’ve never thought of that it could be other than a mind.
I agree that mental properties are not physical properties and that epiphenomenalism is incorrect. Physical objects can have “algorithmic properties” as well as physical properties, it doesn’t mean that computers have minds.
Dr. Craig’s second rebuttal:
R.A2) Absence of evidence is evidence of absence
He expressed his personal opinion that there should be more evidence, but that’s not an argument.
God knows how people will respond to getting more evidence or less evidence and he has to be careful not to take away their free will to disbelieve by piling them up with coercive evidence. God’s goal is not just to convince people that he exists. God’s goal is to have people respond to him and pursue him.
A1) The origin of the universe
2. He said that multiple answers to equations are no problem. But the problem is that you can’t translate multiple answers into a real world context.
The problem is that you are subtracting an identical number from an identical number and getting contradictory results, and that cannot be translated into the real world, where subtraction always gives a definite single result.
He talks about how you can get multiple answers with multiplication by 0. But 0 is not a real quantity, it is just the absence of something, and that cannot translate into the real world, because it has no being.
He says that I am only using evidence from current physics. But that is the point – the evidence of current physics and cosmology supports the beginning of the universe.
3. He said that an umembodied mind can’t be the cause, but we are minds and we cause effects on our physical bodies.
In addition, the design argument supports the idea that the cause of the universe is intelligent.
A2) The fine-tuning of the universe
He says we should be cautious. Of course.
He says the probabilities can’t be assessed. But you can just take the current value and perturb it and see that the resulting universe loses its ability to support life, and you can test an entire range around the current value to see that that vast majority of values in the range don’t permit life.
He says that the current physics is not well-established, but there are so many examples of fine-tuning across so many different areas of science that it is not likely that all of them will be overturned, and the number of finely-tuned constants and quantities has been growing, not shrinking.
He says it doesn’t prove that God is good, and he’s right – that’s what the moral argument is for.
He says that God isn’t efficient enough, but efficiency is only important for those who have limited time and/or limited resources. But God has unlimited time and resources.
He says that the universe is too old, but the large age of the universe is a requirement to support intelligent life – (i.e. – you need third generation stars to provide a stable source of energy to planets, and those stars require that two generations of stars are born and die).
He said what about aliens, and theists are open to that, and God can certainly provide for the salvation of those beings, if they have fallen into sin.
Dr. Millican’s second rebuttal:
R.A1) The origin of the universe
3. Just because epiphenominalism is false, it doesn’t mean that substance dualism is true.
The majority of philosophers of mind do not accept substance dualism.
R.A3) The moral argument
The majority of philosophers are moral realists, but a minority of philosophers are theists. So that means that there must be some way of justifying morality on atheism, which I will not describe right now.
Atheists can express their opinion that humans have intrinsic moral value.
He grants that atheists can perceive moral values. But if atheists can perceive moral values, then why is God needed to enable that?
Atheists can express their opinion that humans are special. We can be rational, and that makes us special.
Atheists can express their opinion that it is good to care about other humans because they are of the same species.
R.A4) The resurrection of Jesus
We don’t have any reasons to believe i the supernatural.
The gospels are written late for the purposes of evangelism.
The gospels are not independent, e.g. Matthew and Luke depend on Q.
John is the latest gospel, and the Christology of John is the highest of all.
The four gospels agree because the early church rejected other (unnamed) gospels that didn’t agree.
Matthew 27 – the earthquake and the raised saints – is not recorded in any other contemporary non-Christian source.
Dr. Craig’s final rebuttal:
A3) The moral argument
He says that human beings are rational, and that gives them value. But atheists like Sam Harris prefer the flourishing of sentient life. He includes non-rational animals as having moral value. So without God, we see that the choice of who or what has moral value is arbitrary. And where would objective moral duties come from if there is no moral lawgiver?
The fact that most atheists accept objective moral values doesn’t mean that they can rationally ground those values on their atheistic worldview. You can’t provide a basis for moral values on atheism by counting the number of atheists who accept objective morality. It’s not surprising that atheists can perceive objective moral values IF they are living in auniverse created by God who grounds these objective moral values and duties that atheists perceive.
A4) The resurrection of Jesus
He cites Geza Vermes and Bart Ehrman as authorities on the historical Jesus, but both of them accept all three of the facts that I presented as minimal facts. Ehrman doesn’t accept the resurrection of Jesus because he presupposes naturalism. He rejects the resurrection on philosophical grounds, not historical grounds.
Dr. Millican’s final rebuttal:
R.A5) Religious experience
Religious experience is an unreliable way to test the claims of a religion, because lots of religions have them and they make contradictory truth claims. In the future, we may discover naturalistic ways of explaining religious experience.
R.A4) The resurrection of Jesus
Even if you can make a case for the resurrection based on these3 minimal facts, there are other stories in the New Testament like Matthew 27 that are quite weird and they undermine the 3 minimal facts that even Geza Vermes and Bart Ehrman accept.
R.A1) The origin of the universe
Bill hasn’t shown that there is any reason for thinking that things don’t come into being, uncaused, out of nothing.
A4) The problem of evil
Theists can’t explain what God’s specific morally sufficient reasons are for permitting the apparently gratuitous evil that we see.
Here’s the full debate on video. Hugh Hewitt is the moderator.
Now I think most people are familiar with Christopher Hitchens and his arguments – he is widely regarded as the top atheist debater in the world, and has written bestselling books on atheism. So below is a little more about the Christian debater William Lane Craig. Craig is regarded as the top defender of Christianity in the world, although many people are unfamiliar with his arguments. Here is a written explanation of the five arguments he uses in the debate with Hitchens, if you want to follow along. This is a good debate for any of you who have never seen a debate on God’s existence before.
William Lane Craig is Research Professor of Philosophy at Talbot School of Theology in La Mirada, California.
Dr. Craig pursued his undergraduate studies at Wheaton College (B.A. 1971) and graduate studies at Trinity Evangelical Divinity School (M.A. 1974; M.A. 1975), the University of Birmingham (England) (Ph.D. 1977), and the University of Munich (Germany) (D.Theol. 1984). From 1980-86 he taught Philosophy of Religion at Trinity… In 1987 they moved to Brussels, Belgium, where Dr. Craig pursued research at the University of Louvain until assuming his position at Talbot in 1994.
He has authored or edited over thirty books, including The Kalam Cosmological Argument; Assessing the New Testament Evidence for the Historicity of the Resurrection of Jesus; Divine Foreknowledge and Human Freedom; Theism, Atheism and Big Bang Cosmology; and God, Time and Eternity, as well as over a hundred articles in professional journals of philosophy and theology, including The Journal of Philosophy, New Testament Studies, Journal for the Study of the New Testament, American Philosophical Quarterly, Philosophical Studies, Philosophy, and British Journal for Philosophy of Science.
