Atheist Luke Muehlhauser interviews well-respect cosmologist Luke Barnes about the fine-tuning argument, and the naturalistic response to it.
Luke M. did a good job explaining the outline of the podcast.
Details:
In one of my funniest and most useful episodes yet, I interview astronomer Luke Barnes about the plausibility of 11 responses to the fine-tuning of the universe. Frankly, once you listen to this episode you will be better equipped to discuss fine-tuning than 90% of the people who discuss it on the internet. This episode will help clarify the thinking of anyone – including and perhaps especially professional philosophers – about the fine-tuning of the universe.
The 11 responses to fine-tuning we discuss are:
“It’s just a coincidence.”
“We’ve only observed one universe, and it’s got life. So as far as we know, the probability that a universe will support life is one out of one!”
“However the universe was configured, evolution would have eventually found a way.”
“There could be other forms of life.”
“It’s impossible for life to observe a universe not fine-tuned for life.”
“Maybe there are deeper laws; the universe must be this way, even though it looks like it could be other ways.”
“Maybe there are bajillions of universes, and we happen to be in one of the few that supports life.”
“Maybe a physics student in another universe created our universe in an attempt to design a universe that would evolve intelligent life.”
“This universe with intelligent life is just as unlikely as any other universe, so what’s the big deal?”
“The universe doesn’t look like it was designed for life, but rather for empty space or maybe black holes.”
“Fine-tuning shows there must be an intelligent designer beyond physical reality that tuned the universe so it would produce intelligent life.”

There is a very good explanation of some of the cases of fine-tuning that I talk about most on this blog – the force of gravity, the strong force, etc. as well as many other examples. Dr. Barnes is an expert, but he is also very very easy to listen to even when talking about difficult issues. Luke M. is very likeable as the interviewer.
Two bears fight it out, and may the best bear win!
This is one of the top 4 best debates that William Lane Craig has done in my opinion. (The other three are Craig-Millican debate and the first and second Craig-Dacey debates).
Sinnott-Armstrong is very courteous, respectful and intelligent scholar and he is very good at defending his side. This is a very cordial and engaging debate, and because it was held in front of a church audience, it was targeted to laymen and not academics. So if you are looking for a good first debate to watch, this is it! Normally, Dr. Craig debates at major universities in front of students and faculty.
There is also a book based on this debate, published by Oxford University Press. I was actually able to find a PDF of it online. I should also remind people that you can get the wonderful Craig-Hitchens debate DVD from Amazon.com if you are looking for a debate to watch, or show in your church, this is the one to start with.
Evil is incompatible with the concept of God (three features all-powerful, all-god, all-knowing)
God’s additional attributes: eternal, effective and personal (a person)
He will be debating against the Christian God in this debate, specifically
Contention: no being has all of the three features of the concept of God
His argument: is not a deductive argument, but an inductive/probabilistic argument
Examples of pointless, unjustified suffering: a sick child who dies, earthquakes, famines
The inductive argument from evil:
If there were an all-powerful and all-good God, then there would not be any evil in the world unless that evil is logically necessary for some adequately compensating good.
There is evil in the world.
Some of that evil is not logically necessary for some adequately compensating good.
Therefore, there can’t be a God who is all-powerful and all-good.
Defining terms:
Evil: anything that all rational people avoid for themselves, unless they have some adequate reason to want that evil for themselves (e.g. – pain, disability, death)
Adequate reason: some evils do have an adequate reason, like going to the dentist – you avoid a worse evil by having a filling
God could prevent tooth decay with no pain
God can even change the laws of physics in order to make people not suffer
Responses by Christians:
Evil as a punishment for sin: but evil is not distributed in accordance with sin, like babies
Children who suffer will go straight to Heaven: but it would be better to go to Heaven and not suffer
Free will: this response doesn’t account for natural evil, like disease, earthquakes, lightning
Character formation theodicy: there are other ways for God to form character, by showing movies
Character formation theodicy: it’s not fair to let X suffer so that Y will know God
God allows evil to turn people towards him: God would be an egomaniac to do that
We are not in a position to know that any particular evil is pointless: if we don’t see a reason then there is no reason
Inductive evil is minor compared to the evidences for God: arguments for a Creator do not prove that God is good
WLC opening speech:
Summarizing Walter’s argument
If God exists, gratuitous evil does not exist.
Gratuitous evil exists.
Therefore, God does not exist.
Gratuitous evil means evil that God has no morally sufficient reason to permit. WSA doesn’t think that all evil is incompatible with God’s existence, just gratuitous evil.
Everyone admits that there are instances of evil and suffering such that we cannot see the morally sufficient reason why God would allow it to occur.
The claim of the atheist is that if they cannot see that there is a moral justification for allowing some instance evil, then there is no moral justification for that instance of evil.
Here are three reasons why we should not expect to know the morally sufficient reasons why God permits apparently pointless evil.
the ripple effect: the morally sufficient reason for allowing some instance of evil may only be seen in another place or another time
Three Christian doctrines undermine the claim that specific evils really are gratuitous
Walter’s own premise 1 allows us to argue for God’s existence, which means that evil is not gratuitous
Christian doctrines from 2.:
The purpose of life is not happiness, and it is not God’s job to make us happy – we are here to know God. Many evils are gratuitous if we are concerned about being happy, but they are not gratuitous for producing the knowledge of God. What WSA has to show is that God could reduce the amount of suffering in the world while still retaining the same amount of knowledge of God’s existence and character.
Man is in rebellion, and many of the evils we see are caused by humans misusing their free will to harm others and cause suffering
For those who accept Christ, suffering is redeemed by eternal life with God, which is a benefit that far outweighs any sufferings and evils we experience in our earthly lives
Arguing for God in 3.
If God exists, gratuitous evil does not exist.
God exists
Therefore, gratuitous evil does not exist.
Four reasons to think that God exists (premise 2 from above):
Two tough rams butt heads, and may the best ram win!
Michael Behe and Keith Fox debate evolution and intelligent design. (See below for link to video)
Details:
Michael Behe is professor of biochemistry at Lehigh University, Pennsylvania and the founder of the modern Intelligent Design movement. His book “Darwin’s Black Box” ignited the controversy 14 years ago when it claimed that certain molecular machines and biological processes are “irreducibly complex” and cannot be explained by Darwinian evolution.
Keith Fox is Professor of biochemistry at the University of Southampton and chairman of Christians in Science. As a theistic evolutionist he believes that Evolution is the best explanation going for the complexity we see and that ID is a blind scientific alley and theologically unappealing to boot.
They debate whether micromachines in the cell such as the “bacterial flagellum” could have evolved by a Darwinian process of evolution. When inference to design is and isn’t acceptable in science. Whether random mutation can mathematically stack up to complex life, and whether God is reduced to a divine “tinkerer” by ID.
Here’s the debate:
Summary
Note: the following debate summary is rated “S” for Snarky. Reader discretion is advised.
Michael Behe:
ID is not Biblical creationism
ID is not religion
ID is a scientific research program
People refuse to discuss ID because of personal philosophical assumptions
ID is like the Big Bang – it is based on evidence, but it has broad religious implications
Keith Fox:
ID is not Biblical creationism, but it isn’t science
Michael Behe:
ID is compatible with common descent
ID is only opposed to unplanned, unguided evolution (Darwinism)
ID is not necessarily opposed to long periods of time
Behe’s first book – the bacterial flagellum
Keith Fox:
Here are a couple of papers that show how parts of the flagellum evolved
They are possible pathways
Michael Behe
No, those are studies that show that there are similarities between bacterial flagella in multiple organisms
Similarities of proteins between different organisms do not necessarily imply a developmental pathway
The problem of having the instructions to BUILD the flagellum still remains
Keith Fox:
Maybe parts of the flagellum had other functions before they were used in the flagellum
Maybe you can use the parts of the flagellum for other purposes
Maybe, one can imagine, it’s possible that!
Michael Behe:
No, parts have to be modified and re-purposed in order to be used for other functions
Keith Fox:
But maybe the proteins can be used in other systems for other things
I re-purpose parts from of designed things to other purposes in my house when I do maintenance
Michael Behe
Uh, yeah – but aren’t you an intelligent designer? What does your home maintenance have to do with Darwinian evolution?
Is ID another God-of-the-gaps argument?
Michael Behe:
Well consider the Big Bang… there was a build-up of scientific evidence for that theory
Just because a theory has religious implications, doesn’t mean that it isn’t true
You really have to look at the specific evidence for a theory, and not decide in advance
Keith Fox: (I’m paraphrasing/inventing/mocking from now on)
But the Big Bang is based on discoveries, and intelligent design is based on gaps in our scientific knowledge
What if I did have evidence of a step by step pathway (which I don’t right now)? Then I would win the argument – what would you do then?
Michael Behe:
Well, if tomorrow you do manage to find expiremental evidence of a pathway, which you don’t have today, then I would be wrong
ID is falsifiable by experimental evidence
But what about your your view? Is that falsifiable by experimental evidence?
What if someone goes into a lab (someone like Scott Minnich?) and performs gene knockout experiments, and publishes the results
You knock out a gene from the bacterial flagellum, you wait for a large number of generations, and it never develops the missing gene
You repeat this with every one of the 50 genes in the bacterial flagellum and it never recovers for any of the 50 genes
There is no pathway to build up even one of the 50 genes – according to actual experiments
What do Darwinists do with experimental evidence that falsifies Darwinism?
Keith Fox:
No, I would not accept that experimental evidence could falsify Darwinism
Just because known published experimental evidence that we have today falsifies Darwinism, it doesn’t mean Darwinism is false because it’s not falsifiable
We don’t know how Darwinism even works – it happened so long ago, and it’s not repeatable or testable, so how could lab ,experiments falsify it?
Darwinism is science and intelligent design is faith, though
Lenski has presided over 50,000 generations, (millions of years of evolution)
The bacterium did evolve and they did get better but not by evolving features, but by disabling features
Keith Fox:
But those are just LAB EXPERIMENTS! What do lab experiments prove?
What if? What if? What if? You don’t know, it happened so long ago, and you weren’t there! You weren’t there!
(clutches Flying Spaghetti Monster idol tighter and sobs pitifully)
Michael Behe:
See, the thing is that I have actual experiements, and here’s some more evidence that just got published last week
So I’ve got evidence and then some more evidence and them some other evidence – experimental evidence
And all the evidence shows that adaptation is done losing traits not by gaining traits
And the published observations are what we see in nature as well
Keith Fox:
But doesn’t Darwinism explain some things that we observe?
Michael Behe:
Well, I am not saying that micro-evolution doesn’t explain some things – it explains bacterial resistance, and other micro-evolution
it just doesn’t explain macro-evolution, and that’s what the experiments show
Keith Fox:
But ID is a science stopper! It stops science! You can’t produce experimental evidence to falsify Darwinism – that would stop science!
Michael Behe:
Well, you have to understand that the Big Bang postulated a non-material cause to the entire physical universe and yet the experimental evidence was allowed to stand because it was testable and verifiable evidence, even if the theory does have religious implications
All explanations in science are design to settle a question and it stops rival explanations that are not as good at explaining the observations
Finding the best explanation stops further study because it is better than rival explanations
Keith Fox:
Well you have to come up with a materialist explanation because that’s the only kind that a functional atheist like me will allow
Michael Behe:
Well, what if the best explanation for an observed effect in nature is non-material, as with the Big Bang?
Keith Fox:
But I have to have a material explanation because I am a functional atheist! (i.e. – a theistic evolutionist = functional atheist)
Michael Behe:
Well what about the cosmic fine-tuning argument? Do you accept that?
That’s an inference to design based on the latest scientific discoveries
Keith Fox:
Well I do accept that argument, but I don’t accept design in biology
When you apply it to biology, somehow it’s bad and you can’t do that or you losing research money and get fired
Anyway, your argument is based on a gap in our current knowledge
Michael Behe:
No, back in Darwin’s time we had a gap in our knowledge – we didn’t know what the cell was – we thought it was jello
Now, we know what the cell is really like, it’s irreducibly complex, and you can’t build up those molecular machines in a step-wise manner
The inference to design is based on the progress of science revealing the increasing levels of complexity
In experiments, Darwinian mechanisms cannot build anything useful, instead genes are disabled or dropped
You guys don’t have the evidence to prove your view that naturalistic mechanisms can do the creating
You keep issuing promissory notes
Keith Fox:
Well, you’re just seeing design subjectively, because you are a non-scientist
I’m being objective when I tell you that we will discover a materialist explanation later on – really really soon now, maybe even tomorrow, yeah
You won’t accept my speculations and you insist on these published experiments
You’re subjective and I’m objective
Just give me more research money so I can hide the decline better
Michael Behe:
Uh, you’re the one who is subjective – I cited evidence, and you are the one who is speculating
You have arguments from credulity, and I’ve got the lab experiments
You refuse to be skeptical, I am the one who is being skeptical
Keith Fox:
Maybe, maybe, maybe! Maybe tomorrow! Maybe in a parallel universe! Maybe aliens from Planet 9 from Outer Space!
Who knows! I certainly don’t know! And that somehow means you don’t know either! See?
Michael Behe:
Well, to prove me wrong, go into the lab, and run experiments and evolve some new genes (using Darwinian mechanisms) that have new useful functionality
Are there limits to what evolution can do?
Michael Behe:
You need multiple changes in the genome to get a new helpful feature (let’s say two specific mutations)
One specific change is possible
the odds are against getting multiple beneficial changes are really really small – you need two SPECIFIC changes to occur in order
Keith Fox:
Well, lots of things are really unlikely – any permutation of dice rolls is as unlikely as any other
Michael Behe:
Well, we are talking about TWO SPECIFIC mutations that are needed to get a beneficial function – lots of other mutations are possible, but we are looking for a specific outcome that requires two SPECIFIC mutations out of the whole genome
You aren’t going to get useful outcomes unless you direct the mutations
