Robin Collins lectures on fine-tuning for discoverability from particle physics

2 Comments

This lecture is 29 minutes long, the Q&A is 15 minutes. I highly recommend this lecture to all audiences of all levels of ability, for the simple reasons that apart from the content, this lecture is a how-to clinic in the tone, body language, slides and so on for you to use when trying to be persuasive when making your case. Science is king in this lecture. The scientific method is defined and applied in a winsome way. Making science understandable should be the bread and butter approach to Christian apologetics, and this lecture rivals the Mike Strauss lecture at Stanford University and the Mike Strauss lecture at the University of Texas – Dallas as the ideal lectures for showing that. It’s not just the scientific material that makes this lecture by Collins work, it’s the narrative and the style that make the lecture work.

About Robin Collins:

Robin Collins (PhD, University of Notre Dame, 1993), is professor of philosophy at Messiah College, Grantham, PA specializing in the area of science and religion.  He has written over twenty-five articles and book chapters on a wide range of topics, such as the fine-tuning of the cosmos as evidence for the existence of God, evolution and original sin, the Doctrine of Atonement, Asian religions and Christianity, and Bohm’s theory of quantum mechanics.  Some of his most recent articles/book chapters are “Philosophy of Science and Religion” in The Oxford Handbook of Science and Religion, “Divine Action and Evolution” in The Oxford Handbook of Philosophical Theology (2009)  “The Multiverse Hypothesis: A Theistic Perspective,” in Universe or Multiverse? (Cambridge University Press), and “God and the Laws of Nature,” in Theism or Naturalism: New Philosophical Perspectives (Oxford University Press, forthcoming).  He recently received a grant from the John Templeton Foundation to finish a book that presents the case for design based on physics and cosmology,  tentatively entitled The Well-Tempered Universe: God, Cosmic Fine-tuning, and the Laws of Nature.

His thesis in one slide:

Fine-tuning for discoverability
Fine-tuning for discoverability – the DLO thesis

Summary:

  • Thesis: the universe is more intelligible than we would expect it by chance
  • The regular fine-tuning argument says that complex embodied observers are very rare
  • But the number of highly-discoverable universes that have complex embodied observers is rarer still
  • Why do we exist in a highly-discoverable universe?
  • Can we quantify and test discoverability?
  • Yes: by varying fundamental parameters and seeing how it affects discoverability
  • Conclusion of his calculations: The Discoverability-Liveability Optimality range is an even smaller range within the Liveablity Optimality range of the standard fine-tuning argument
  • Fine-tuning #1: the fine structure constant, governs the strength of the electro-magnetic force
  • If larger, wood-burning fire becomes impossible because fires won’t stay lit, and therefore forging metals becomes unlikely
  • If smaller, wood-burning fires won’t go out, e.g. – from lightning strikes, so that wood would be less accessible
  • Other constraints: smaller value decreases effectiveness of light microscopes, drastically lowers efficiency of transformers and motors
  • Fine-tuning #2: the cosmic microwave background radiation (CMBR), radiation left over from the Big Bang
  • humans need to discover the CMBR in order to confirm the Big Bang creation out of nothing, and it depends on baryon/pothon ratio
  • his calculations show that the actual value of CMBR is exactly at the peak for detectability by humans
  • if baryon/photon ratio larger, CMBR is less discoverable
  • if baryon/photon ratio smaller, CMBR is less discoverable
  • Fine-tuning #3: parameters related to subatomic particles are fine-tuned for their discovery and usefulness, e.g. – the bottom quark, the charm quark, the tau lepton and the Higgs Boson
  • the lifetime of the particles affects their usefulness to scientists who want to investigate the Standard Model of physics
  • decay rates of these subatomic particles are related to several of the finely-tuned parameters
  • for example, the mass of the bottom quark is finely-tuned for its discoverability by scientists
  • the tau lepton and the charm quark are similarly fine-tuned for disoverability
  • the mass of the Higgs boson is finely-tuned for discoverability and for making further discoveries
  • Conclusion: the DLO thesis is strongly confirmed – this is an even greater degree of fine-tuning that the already astonishing probabilities of the fine-tuning for complex, embodied intelligent beings
  • The formalized version of the philosophical argument based on this evidence is impervious with some of the traditional objections to the standard fine-tuning argument
  • #1 multiverse/selection effect: it is not subject to multiverse / observer selection objections
  • #2 normalizeability: it is not subject to the McGrew-Vestrup objection because the range of possible values is finite not infinite
  • #3 falsifiability: it makes falsifiable predictions, and in fact Collins’ earlier calculations of the CMBR discoverability contained an error that falsified the thesis – until he found the error and corrected for it
  • #4 usefulness: it gives clues about the Creator’s purpose for us, namely that the universe was created for us to be able to do science and find evidence of the Creator’s existence – there is no expectation for us to exercise blind faith, trust in God is meant to be a plausible deduction from the progress of experimental science

Earlier, I blogged about a Robin Collins lecture on the fine-tuning that allows complex, embodied life to exist. Another must-see lecture. If you are looking for something to study in university, and you have funding, then physics, mathematics and philosophy are the best places to be for a Christian scholar.

What helps young men resist peer disapproval?

Tough enough to not care about peer pressure
Tough enough to not care whether you approve of what he’s doing

A post by Nick Peters about young people and apologetics, at the Christian Apologetics Alliance blog.

Excerpt:

Now picture a teenage youth who is a Christian. Is he on the outs with his peers in any way? Well if he’s a good and observant Christian, he’ll be a virgin (since most teenagers in high school aren’t married). Will that lead to any shame to his peers? Yep. Especially since they consider “getting laid” to be a rite of passage and a sign that you are a real man or woman.

So what happens with a boy who’s seventeen and can drive and who is with the guys who are talking about their sexual exploits and the guy has nothing to contribute? If he is asked why he’s not “getting some” he replies that he is a Christian. Is that going to win him any friends? Nope. His “friends” there will most likely mock him for believing in antiquated ideas that science has disproven and tell him he needs to get with the times. Result? The young man is shamed.

Now imagine instead if he’s told the latter part about how his ideas are antiquated and instead, he’s able to make a rational case for the resurrection of Jesus from the dead. Do you think he’ll be able to be shamed the same way? Sure, his friends can still mock him, but he can take the mockery as a sign that they cannot answer his arguments. The young boy has honor then, rather than shame. He might not be sleeping around, but he can hold his head high knowing he can stand up against his peers.

[…]No one wants to be embarrassed, and that includes youth, but if our young people think they can do something that none of their peers can do, it will help them to have that honor that they seek, and there is nothing wrong with seeking honor. Remember the parable where Christ told us to take a lowly position at a banquet so our host would say, “Move up to a better place” and we would be honored? He was saying that that is the proper way to receive honor. Don’t just go out and try to grab it. Let it be given to you.

There are many things that a young person can be ashamed of, but if they’re intellectually unprepared, being a Christian is something that they may be shamed for. In the face of temptation, they need a reason to be obedient rather than just, “The church says so” or “Mom and Dad say so.” Neither of those will be seen as honorable positions. They need to know for themselves why it is that they hold the stance that they do. If they are waiting until marriage, they need to know why. If they believe a man rose from the dead, they need to know why.

That youth are eating this stuff up should tell us something. Youth don’t want to be shamed in the eyes of their contemporaries. They won’t mind holding a different position as long as they can defend that position. If they cannot, then the tide of social pressure could be enough to get them to abandon that and if their emotions and wills start acting against Christianity, it is only a matter of time until the intellect follows.

That excerpt is basically a summary of my life – that’s how I started out as a teen – with apologetics. I’ve been a Christian the whole time in between then and now. I think many parents and churches are wondering how it is that you get a young man to stand up to the culture and peer pressure. The answer is apologetics, and I think integrating Christianity with every other area of knowledge helps as well. Winning arguments over and over is an excellent way to build a suit of armor against temptation and peer pressure.

And in speaking to young people who were raised as Christians then fell away, the common denominator is that they were uncomfortable claiming to be Christians in a secular environment. We have to have a plan to help our young people deal with pluralism and peer pressure. Apologetics is the best answer I can think of.

Polemics

If you find a discrepancy in the Bible, does that mean Jesus didn’t exist?

Let's think clearly about Christianity
Let’s think clearly about Christianity

Even if we don’t know whether there was one angel or two angels at Jesus’ tomb, we can still know things about whether God exists and whether Jesus rose from the dead.

First, we can know that the universe was created and designed because of reliable, experimental evidence that the universe came into being and is finely-tuned for life. And second, we can know that Jesus was buried, that his tomb was found empty, that a variety of people had experiences of him appearing to them after his death, and that the Christian movement had an early belief that he was resurrected from the dead. We know those core things like we know anything – because we have good evidence. Other things that are more peripheral may not be as supported by evidence. We can remain agnostic about those peripheral things, but that agnosticism about peripheral things doesn’t undermine the things that we know.

William Lane Craig answered a question related to this problem for a person who accepted the minimal facts case for the resurrection but then though that someone this case couldn’t work unless he accepted inerrancy as well.

Here’s the question:

After re-evaluating my Christian faith and pruning it for two years, I can’t shake what seem like two disparate conclusions. One is that the evidence for Jesus resurrection is impecable. But the other is that there seem to be some very awkward realities about the composition of scripture (like errors or authors claiming to write by another name). Yet, the authors of the New Testament, including Jesus, seem to use Scripture in a way that assumes it is word for word from God.

While inductive logic is used to arrive at a strong historical case for the resurrection of Jesus, inductive logic can also be used to arrive at a strong case for many of the peculiaraties about Scripture previously mentioned.

It seems that the approach which many apologists take at this point is that, having established the authority of Jesus by the resurrection, if the argument being raised against scripture contradicts an opinion expressed by Jesus in the Gospels, then the argument for a contradiction must have no possible harmonizations for it to really stick. But I don’t see how this is fair to say, since (1) it seems unfair to use inductive logic to evidence Jesus’ resurrection but then not use it for criticisms against the Bible and (2) an inductive argument can be strong despite what Jesus as recorded in the Gospels says, especially since we cannot assume the precision with which many of the saying were recorded. And (3), anybody can cook up a harmonization of some verse that is possible but not plausible, which I am sure you have seen first hand many times.

Yet, holding these two positions in tension tends to be corrosive to my faith and ultimately leads to a certain bitterness against God for allowing the biblical writers to play fast-and-loose with his words and for not providing a clarity that brings more certainty about what is from him and what isn’t. Any help you can give to relieve this tension would be greatly appreciated.

Now Dr. Craig has a long response on his Reasonable Faith web site, but I just want to quote you this:

But secondly, suppose you’ve done all that and are still convinced that Scripture is not inerrant.  Does that mean that the deity and resurrection of Christ go down the drain?  No, not all.  […]As you recognize, we have a very strong case for the resurrection of Jesus.  That case in no way depends on the Bible’s being inerrant.  This became very clear to me during my doctoral studies in Munich with Wolfhart Pannenberg.  Pannenberg had rocked German theology by maintaining that a sound historical case can be made for the resurrection of Jesus.  Yet he also believed that the Gospel resurrection appearances stories are so legendary that they have scarcely a historical kernel in them!  He did not even trust the Markan account of the discovery of the empty tomb.  Rather his argument was founded on the early pre-Pauline tradition about the appearances in I Corinthians 15.3-5 and on the consideration that a movement based on the resurrection of dead man would have been impossible in Jerusalem in the face of a tomb containing his corpse.

Evangelicals sometimes give lip service to the claim that the Gospels are historically reliable, even when examined by the canons of ordinary historical research; but I wonder if they really believe this.  It really is true that a solid, persuasive case for Jesus’ resurrection can be made without any assumption of the Gospels’ inerrancy.

By contrast, the case for Jesus’ belief that the Old Testament Scriptures are inerrant is much weaker.  I think there’s no doubt that (5) is the premiss that would have to go if biblical inerrancy were to be abandoned.  We should have to re-think our doctrine of inspiration in that case, but we needn’t give up belief in God or in Jesus, as Bart Ehrman did.  Ehrman had, it seems to me, a flawed theological system of beliefs as a Christian.  It seems that at the center of his web of theological beliefs was biblical inerrancy, and everything else, like the beliefs in the deity of Christ and in his resurrection, depended on that. Once the center was gone, the whole web soon collapsed.  But when you think about it, such a structure is deeply flawed.  At the center of our web of beliefs ought to be some core belief like the belief that God exists, with the deity and resurrection of Christ somewhere near the center.  The doctrine of inspiration of Scripture will be somewhere further out and inerrancy even farther toward the periphery as a corollary of inspiration.  If inerrancy goes, the web will feel the reverberations of that loss, as we adjust our doctrine of inspiration accordingly, but the web will not collapse because belief in God and Christ and his resurrection and so on don’t depend upon the doctrine of biblical inerrancy.

We have mainstream scientific evidence for God’s existence, and a mainstream historical evidence for a minimal facts case for the resurrection. None of that evidence depends on inerrancy being true.

So can we please just accept what can be known from experimental science and standard historical methods, and work our lives around that, and not nitpick about peripheral issues so much? I am inerrantist, and so is Dr. Craig. But you don’t have to be in order to accept that the mainstream evidence that shows that universe was created and fine-tuned, and that Jesus was raised bodily from the dead. Don’t let “one angel vs two angels “stop you from accepting things we can know. You can just stay agnostic about the things you think we don’t know.
