MIT physicist Alan Lightman on fine-tuning and the multiverse

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 fine-­tuning 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, 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.

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. I don’t think it’s like that the last 100 years of scientific progress on the origins question are going to be overturned so that science once again affirms what atheists believe about the universe. Things are going the wrong way for atheists – at least with respect to science.

See it in action

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 maintain their current pre-scientific view. That’s not what rational people ought to do when confronted with evidence.

How the presence and quality of fathers affects belief in God

Does government provide incentives for people to get married?
A father in the home helps children to reconcile love and moral boundaries

Here’s an article by Paul Copan which points out how father presence/absence and father quality affects belief and disbelief in God.

Excerpt:

Seventh, the attempt to psychologize believers applies more readily to the hardened atheist.It is interesting that while atheists and skeptics often psychoanalyze the religious believer, they regularly fail to psychoanalyze their ownrejection of God. Why are believers subject to such scrutiny and not atheists? Remember another feature of Freud’s psychoanalysis — namely, an underlying resentment that desires to kill the father figure.

Why presume atheism is the rational, psychologically sound, and default position while theism is somehow psychologically deficient? New York University psychology professor Paul Vitz turns the tables on such thinking. He essentially says, “Let’s look into the lives of leading atheists and skeptics in the past. What do they have in common?” The result is interesting: virtually all of these leading figures lacked a positive fatherly role model — or had no father at all.11

Let’s look at some of them.

  • Voltaire(1694–1778): This biting critic of religion, though not an atheist, strongly rejected his father and rejected his birth name of François-Marie Arouet.
  • David Hume(1711–76): The father of this Scottish skeptic died when Hume was only 2 years old. Hume’s biographers mention no relatives or family friends who could have served as father figures.
  • Baron d’Holbach(1723–89): This French atheist became an orphan at age 13 and lived with his uncle.
  • Ludwig Feuerbach (1804–72): At age 13, his father left his family and took up living with another woman in a different town.
  • Karl Marx(1818–83): Marx’s father, a Jew, converted to being a Lutheran under pressure — not out of any religious conviction. Marx, therefore, did not respect his father.
  • Friedrich Nietzsche(1844–1900): He was 4 when he lost his father.
  • Sigmund Freud(1856–1939): His father, Jacob, was a great disappointment to him; his father was passive and weak. Freud also mentioned that his father was a sexual pervert and that his children suffered for it.
  • Bertrand Russell(1872–1970): His father died when he was 4.
  • Albert Camus(1913–60): His father died when he was 1 year old, and in his autobiographical novel The First Man, his father is the central figure preoccupation of his work.
  • Jean-Paul Sartre(1905–80): The famous existentialist’s father died before he was born.12
  • Madeleine Murray-O’Hair (1919–95): She hated her father and even tried to kill him with a butcher knife.
  • We could throw in a few more prominent contemporary atheists not mentioned by Vitz with similar childhood challenges:
  • Daniel Dennett (1942–): His father died when he was 5 years of age and had little influence on Dennett.13
  • Christopher Hitchens (1949–): His father (“the Commander”) was a good man, according to Hitchens, but he and Hitchens “didn’t hold much converse.” Once having “a respectful distance,” their relationship took on a “definite coolness” with an “occasional thaw.” Hitchens adds: “I am rather barren of paternal recollections.”14
  • Richard Dawkins (1941–): Though encouraged by his parents to study science, he mentions being molested as a child — no insignificant event, though Dawkins dismisses it as merely embarrassing.15

Moreover, Vitz’s study notes how many prominent theists in the past — such as Blaise Pascal, G.K. Chesterton, Karl Barth, and Dietrich Bonhoeffer — have had in common a loving, caring father in their lives.16

Not only is there that anecdotal evidence, but there is also statistical evidence.

Excerpt:

In 1994 the Swiss carried out an extra survey that the researchers for our masters in Europe (I write from England) were happy to record. The question was asked to determine whether a person’s religion carried through to the next generation, and if so, why, or if not, why not. The result is dynamite. There is one critical factor. It is overwhelming, and it is this: It is the religious practice of the father of the family that, above all, determines the future attendance at or absence from church of the children.

If both father and mother attend regularly, 33 percent of their children will end up as regular churchgoers, and 41 percent will end up attending irregularly. Only a quarter of their children will end up not practicing at all. If the father is irregular and mother regular, only 3 percent of the children will subsequently become regulars themselves, while a further 59 percent will become irregulars. Thirty-eight percent will be lost.

If the father is non-practicing and mother regular, only 2 percent of children will become regular worshippers, and 37 percent will attend irregularly. Over 60 percent of their children will be lost completely to the church.

Let us look at the figures the other way round. What happens if the father is regular but the mother irregular or non-practicing? Extraordinarily, the percentage of children becoming regular goesupfrom 33 percent to 38 percent with the irregular mother and to 44 percent with the non-practicing, as if loyalty to father’s commitment grows in proportion to mother’s laxity, indifference, or hostility.

[…]In short, if a father does not go to church, no matter how faithful his wife’s devotions, only one child in 50 will become a regular worshipper. If a father does go regularly, regardless of the practice of the mother, between two-thirds and three-quarters of their children will become churchgoers (regular and irregular). If a father goes but irregularly to church, regardless of his wife’s devotion, between a half and two-thirds of their offspring will find themselves coming to church regularly or occasionally.

A non-practicing mother with a regular father will see a minimum of two-thirds of her children ending up at church. In contrast, a non-practicing father with a regular mother will see two-thirds of his children never darken the church door. If his wife is similarly negligent that figure rises to 80 percent!

The results are shocking, but they should not be surprising. They are about as politically incorrect as it is possible to be; but they simply confirm what psychologists, criminologists, educationalists, and traditional Christians know. You cannot buck the biology of the created order. Father’s influence, from the determination of a child’s sex by the implantation of his seed to the funerary rites surrounding his passing, is out of all proportion to his allotted, and severely diminished role, in Western liberal society.

Basically, anyone who doesn’t have a benevolent, involved father is going to have an more difficult time believing that moral boundaries set by an authority are for the benefit of the person who is being bounded. The best way to make moral boundaries stick is to see that they apply to the person making the boundaries as well – and that these moral boundaries are rational, evidentially-grounded and not arbitrary. It is therefore very important to children to be shepherded by a man who studied moral issues (including evidence from outside the Bible) in order to know how to be persuasive to others. If you want your child to be religious and moral, you have to pick a man who is religious and moral. And it can’t just be a faith commitment that he makes, he can just lie about that. Women ought to check whether men are bound to what they believe by checking what they’ve read. A man usually acts consistently with what he believes, and beliefs only get formed when a man informs himself through things like reading.

My advice to Christian women is this. When you are picking a man, be sure and choose one who is already invested in Christian things and producing results. It’s very unlikely that he’s going to start from nothing after you marry him. If you value your kids, make a man’s interest in developing and acting on a Christian worldview the main thing you are looking for.

Is the presuppositionalist approach to apologetics Biblical?

Bible study that hits the spot
Bible study that hits the spot

Here’s J.W. Wartick’s take from Always Have a Reason blog.

Excerpt:

Cornelius Van Til pioneered the field of “presuppositional apologetics” primarily through his works Christian Apologetics and The Defense of the Faith. His arguments are easily misunderstood as question begging or viciously circular. Herein, I have presented a brief outline and analysis which reveals that while the presuppositional approach may indeed have some logical faults, the overall system has a certain power to it and can be integrated into a total-apologetic system.

[…]The key to understand here is that Van Til does not accept that there is a neutral reason “out there” by which Christians and non-Christians can arbitrate the truth of Christianity; his point is that there is no neutral ground and that one’s presuppositions will determine one’s end point. Again, he writes, “this [apologetic method] implies a refusal to grant that any area or aspect of reality, any fact or any law of nature or of history, can be correctly interpreted except it be seen in the light of the main doctrines of Christianity” (Christian Apologetics, 124).

However, Van Til takes it even further and argues that one must presuppose the truth of Christianity in order to make sense of reality: ” What is the content of this presupposition, then? It is this: “I take what the Bible says about God and his relation to the universe as unquestionably true on its own authority” (The Defense of the Faith, 253); again, “The Bible is thought of as authoritative on everything of which it speaks. Moreover, it speaks of everything” (Christian Apologetics, 19). Thus, Van Til’s apologetic does not make Christianity the conclusion of an argument; rather, Christianity is the starting presupposition.

The presuppositional approach here cannot be stressed enough. For Van Til, one simply cannot grant to the non-Christian any epistemic point. “We cannot avoid coming to a clear-cut decision with respect to the question as to whose knowledge, man’s or God’s, shall be made the standard of the other. …[O]ne must be determinative and the other subordinate” (The Defense of the Faith 62-63).

What place is had for evidences in Van Til? At some points, he seems to be very skeptical of the use of Christian evidences. In particular, the fact that he argues there is no neutral evaluation grounds between the Christian and non-Christian seems to imply that  there can be no real evaluation of such arguments apart from Christianity. One of Van Til’s most famous illustrations of the use of evidences can be found in The Defense of the Faith pages 332 and following. He uses three persons, Mr. Black (non-Christian), Mr. Grey (Christian non-presuppositionalist), and Mr. White (presuppositional/reformed apologist):

Mr. Grey… says that, of course, the “rational man” has a perfect right to test the credibility of Scripture by logic… by experience… [Mr. Grey then takes Mr. Black a number of places to show him various theistic evidences. Mr. Black responds:] “you first use intellectual argument upon principles that presuppose the justice of my unbelieving position. Then when it it is pointed out to you that such is the case, you turn to witnessing [subjectively].

…At last it dawned upon Mr. White that first to admit that the principles of Mr. Black, the unbeliever, are right and then to seek to win him to the acceptance of the existence of God the Creator… is like first admitting that the United States had historically been a province of the Soviet Union but ought at the same time to be recognized as an independent and all-controlling power… If one reasons for the existence of God and for the truth of Christianity on the assumptions that Mr. Black’s principles of explanation are valid, then one must witness on the same assumption [which makes witnessing wholly subjective.] (p. 332-339)

It can be seen here that even evidences for Van Til must be based within a presupposition. There is no way to look at evidences in the abstract. One can either offer them within the presuppositions of Christianity or outside of Christianity. For Van Til, once one has agreed to offer evidences outside of Christianity, one has granted the presuppositions of the non-believer, and therefore is doomed to fail.

This would include using arguments like the cosmological argument, the fine-tuning argument, arguments from miracles, etc. – including the resurrection. That seems to be Van Til’s view. No evidence allowed – you have to presuppose Christianity is true in order to make sense of the world.

Now, I think we need to make a distinction between using questioning the pre-suppositions of our opponents, as with William Lane’s Craig’s moral argument, Plantinga’s epistemological argument for reason and Menuge’s ontological argument for reason. There are arguments for theism that question the pre-suppositions of an atheist. Certainly, non-theists cannot ground things like morality, free will, consciousness and rationality on atheism. But that’s not what Van Til is saying. He says that an atheist cannot be swayed by evidence unless he first becomes a Christian. I.e. – he is saying that atheist Anthony Flew is lying when he says that evidence caused him to turn to believe in God. On Van Til’s view, that’s impossible.

My view of presuppositional apologetics is that is as a system, it is circular reasoning. It assumes Christianity in order to prove Christianity. But there is an even worse problem with it. It’s not a Biblical way of doing apologetics. It’s man’s way of doing apologetics, not God’s. I think that the best way to understand Van Til’s apologetics is by saying that it really just a sermon disguised as apologetics. The problem is that Van Til’s sermon has no basis in the Bible. Wherever he is getting his view from, it’s not from the Bible. When I look the Bible, I don’t see any Biblical support for the view that pre-suppositional apologetics is the only approved way of defending the faith. Instead, the standard method seems to be evidentialism.

In Romans 1, Paul writes that people can learn about God’s existence from the natural world.

Romans 1:18-23:

18The wrath of God is being revealed from heaven against all the godlessness and wickedness of men who suppress the truth by their wickedness,

19since what may be known about God is plain to them, because God has made it plain to them.

20For since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that men are without excuse.

21For although they knew God, they neither glorified him as God nor gave thanks to him, but their thinking became futile and their foolish hearts were darkened.

22Although they claimed to be wise, they became fools

23and exchanged the glory of the immortal God for images made to look like mortal man and birds and animals and reptiles.

And in Acts, Peter appeals to eyewitness testimony for the resurrection, and Jesus’ miracles.

Acts 2:22-24, and 36:

22“Men of Israel, listen to this: Jesus of Nazareth was a man accredited by God to you by miracles, wonders and signs, which God did among you through him, as you yourselves know.

23This man was handed over to you by God’s set purpose and foreknowledge; and you, with the help of wicked men, put him to death by nailing him to the cross.

24But God raised him from the dead, freeing him from the agony of death, because it was impossible for death to keep its hold on him.

And finally from the same chapter:

36“Therefore let all Israel be assured of this: God has made this Jesus, whom you crucified, both Lord and Christ.”

Professor Clay Jones of Biola University makes the case that the use of evidence when preaching the gospel was standard operating procedure in the early church. (H/T Apologetics 315)

Intro:

In 1993 I started working for Simon Greenleaf University (now Trinity Law School) which offered an M.A. in Christian apologetics (Craig Hazen was the director). Much of my job was to promote the school and although I had studied Christian apologetics since my sophomore year in high school, I decided I needed to see whether an apologetic witness had strong Biblical precedence.

It does.

As I poured through the Scripture I found that Jesus and the apostles preached the resurrection of Christ as the sign of the truth of Christianity.

What follows are some of the passages which support the resurrection witness.

Here is my favorite verse from his massive list list of verses in favor of the evidential approach to Christian apologetics:

Mat. 12:39-40: A wicked and adulterous generation asks for a miraculous sign! But none will be given it except the sign of the prophet Jonah. For as Jonah was three days and three nights in the belly of a huge fish, so the Son of Man will be three days and three nights in the heart of the earth.

Jesus is saying that the resurrection was deliberately given as a sign to unbelievers to convince them. (“The Sign of Jonah” = the resurrection)

So, I see that God uses nature and miracles to persuade, which can be assessed using scientific and historical methods. Can anyone find me a clear statement in the Bible that states that only pre-suppositional arguments should be used? I could be wrong, and I am willing to be proven wrong. I think we should use the Biblical method of apologetics, not the fallen man’s method of apologetics.
