Brian Auten interviews philosopher Robin Collins on the fine-tuning argument

1 Comment

Here’s a must-listen interview from Apologetics 315.

Details:

Today’s interview is with Robin Collins, professor of philosophy at Messiah College. His training is in physics and in philosophy and he is a leading advocate for using the fine-tuning of the universe as a design argument for theism. He talks about his background and training, the fine-tuning argument, the different types of fine-tuning with examples and illustrations (laws, constants and initial conditions), two different ways of presenting the fine-tuning argument, answering common objections to the argument, the uniqueness of life, variations of the multiverse hypothesis, the failure of multiverse theory to explain away fine-tuning, objections to Victor Stenger, upcoming books, simplifying the fine-tuning argument for practical use, common mistakes when presenting the argument, the most common objection (who designed God?), and more.

Dr. Collins is extremely cautious and circumspect in his assessment of the fine-tuning argument. He takes the objections to the argument, like the multiverse, seriously and that comes across in the interview. He is familiar with criticisms of the argument and he has engaged with skeptics like Victor Stenger in his published work. I highly recommend it. It is a little more suited to intermediate-level Christians, but not so advanced that it’s impossible for non-math beginners to follow the broad thrust of what’s being said.

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.

The fine-tuning argument

Here’s a short article where Collins gives TWO examples of the fine-tuning. He is very modest in his argument, merely asserting that the fine-tuning is more compatible with theism than it is with atheism.

Excerpt:

Science is commonly thought to have undercut belief in God. As Nobel Prize winning physicist Steven Weinberg famously remarked, “the more we find out about the universe, the more meaningless it all seems.” Yet, the discoveries of modern physics and cosmology in the last 50 years have shown that the structure of the universe is set in an extraordinarily precise way for the existence of life; if its structure were slightly different, even by an extraordinarily small degree, life would not be possible. In many people’s minds, the most straightforward explanation of this remarkable fine-tuning is some sort of divine purpose behind our universe.

This fine-tuning falls into three categories: the fine-tuning of the laws of nature, the fine-tuning of the constants of physics, and the fine-tuning of the initial conditions of the universe. “Fine-tuning of the laws of nature” refers to the fact that if the universe did not have precisely the right combination of laws, complex intelligent life would be impossible. If there were no universal attractive force (law of gravity), for example, matter would be dispersed throughout the universe and the energy sources (such as stars) needed for life would not exist. Without the strong nuclear force that binds protons and neutrons together in the nucleus, there would not be any atoms with an atomic number greater than hydrogen, and hence no complex molecules needed for life. And without the Pauli-exclusion principle, all electrons would fall to the lowest orbital of an atom, undercutting the kind of complex chemistry that life requires.

Some fundamental physical numbers governing the structure of the universe—called the constants of physics—also must fall into an exceedingly narrow range for life to exist. For example, many have estimated that the cosmological constant—a fundamental number that governs the expansion rate of empty space—must be precisely set to one part in 10120 in order for life to occur; if it were too large, the universe would have expanded too rapidly for galaxies and stars to form, and if it were too small, the universe would have collapsed back on itself. As Stephen Hawking wrote in his book A Brief History of Time, “The remarkable fact is that the values of these numbers [i.e. the constants of physics] seem to have been very finely adjusted to make possible the development of life.” Finally, the initial distribution of mass energy at the time of the big bang must have an enormously special configuration for life to occur, which Cambridge University mathematical physicist Roger Penrose has calculated to be on the order of one part in 1010123. This is an unimaginably small number.

I know what you’re thinking: How do we know that non-Christian scientists acknowledge the fine-tuning of gravity in the way that Collins describes?

Well, the New Scientist actually talks about the fine-tuning of the force of gravity. And they’re not Christians.

Excerpt:

The feebleness of gravity is something we should be grateful for. If it were a tiny bit stronger, none of us would be here to scoff at its puny nature.

The moment of the universe‘s birth created both matter and an expanding space-time in which this matter could exist. While gravity pulled the matter together, the expansion of space drew particles of matter apart – and the further apart they drifted, the weaker their mutual attraction became.

It turns out that the struggle between these two was balanced on a knife-edge. If the expansion of space had overwhelmed the pull of gravity in the newborn universe, stars, galaxies and humans would never have been able to form. If, on the other hand, gravity had been much stronger, stars and galaxies might have formed, but they would have quickly collapsed in on themselves and each other. What’s more, the gravitational distortion of space-time would have folded up the universe in a big crunch. Our cosmic history could have been over by now.

Only the middle ground, where the expansion and the gravitational strength balance to within 1 part in 1015at 1 second after the big bang, allows life to form.

Here’s a very long paper by Collins on the fine-tuning argument, where he answers several objections to the argument, including the multiverse/many-universe hypothesis.

If you want a longer response to the multiverse argument, but you don’t want to shell out big bucks for Collins’ chapter in the “Blackwell Companion to Natural Theology“, then you can just get James Sinclair’s essay in “Contending With Christianity’s Critics“.

Advice for Christians who discuss their faith with atheists… from an atheist

15 Comments

I spotted this post by Jeffery Jay Lowder on The Secular Outpost, and I think it’s good advice.

There are times where two people speak the same language, use the same words, and mean very different things by the same words. In conversations between Christians and atheists, “faith” is one such word. For many atheists, the word “faith” means, by default, belief without evidence or even belief against the evidence. In contrast, I doubt many Christians would accept that definition. For example, according to the NIV translation, Hebrews 11:1 states, “Now faith is confidence in what we hope for and assurance about what we do not see.”

Victor Reppert, at Dangerous Idea, writes this about the word “faith.”

Every time you use the word “faith” in a discussion with an atheist, they are going to declare victory. They will presume that you are believing for no reason, and that you are are admitting that the evidence is against you.

I think he is probably right. If Christians want to dialogue with atheists, I think Christians would be well served to speak the ‘language’ of atheists. The word “faith” simply has too much baggage associated with it; inserting that word into the conversation is likely to become a distraction from whatever point the Christian was probably trying to make. So if you’re a Christian talking with atheists, my advice is to temporarily delete the word “faith” from your vocabulary. Find some other way to make your point.

A better word to use is “trust”, and here’s Christian apologist Greg Koukl of Stand to Reason to make the same point:

Christian apologist Jonathan Morrow had a similar post on Think Christianly. (Mark well the part he put in bold)

Excerpt:

In today’s post I want to share a conversation I had with some of the sharp young men during lunch. It had to do with how we talk about Christianity with our friends, family, and coworkers. Most of the time, well meaning Christians talk about Christianity in the context of religion…not reality. Is that a problem? Yes, and here’s why. Religion is understood as a personal and private feeling that is not accessible by everyone else. You can’t question, challenge, or investigate it; you must simply be tolerant of it (and by tolerant, I am using the modern misunderstanding of tolerance which believes that all religious views are equally valid simply because a person sincerely believes them). That’s why having a conversation about Christianity as a religion is a dead end. It’s a non-starter.

That’s why I encouraged these students to talk about Christianity in the context of reality where terms like truth, knowledge, reason, and evidence apply. Any claim about reality is either true or false (it can’t be both). If Christianity is not the kind of thing that can be true or false…the battle has already been lost and the Gospel cannot be seriously considered. We need to talk about Christianity in the same way we talk about having a prescription filled at the pharmacy or receiving instruction from a Doctor.

In today’s society, religion is a fuzzy (i.e., socially constructed or psychologically projected) category that makes little difference in everyday life. But if Christianity is true, then it speaks to ALL of life. It makes a comprehensive claim on reality. Jesus didn’t intend to merely address two hours of our week. As Christians we need to have more conversations about reality and less about religion.

I’ve even written a post about the concept of faith that is presented in the Bible and the word faith has nothing to do with blind belief in the Bible – it’s always based on evidence, so that people can know for certain what the truth is. I highly recommend it for anyone who disagrees with Jeffery,Greg or Jonathan. When you’re talking about Christianity, you’re talking about what you know. You’re talking about the way the world is, for everyone. When you talk about your belief in God, you should say “trust”. You should not say “faith”.

Positive arguments for Christian theism

Polemics

Does atheism mean “a lack of belief in God”?

27 Comments

First, let’s see check with the Stanford University Encyclopedia of Philosophy.

Excerpt:

‘Atheism’ means the negation of theism, the denial of the existence of God.

Stanford University is one of the top 5 universities in the United States, so that’s a solid definition. To be an atheist is to be a person who makes the claim that, as a matter of FACT, there is no intelligent agent who created the universe. Atheists think that there is no God, and theists think that there is a God. Both claims are objective claims about the way the world is out there, and so both sides must furnish forth arguments and evidence as to how they are able to know what they are each claiming.

Philosopher William Lane Craig has some thoughts on atheism, atheists and lacking belief in God in this reply to a questioner.

Question:

In my discussions with atheists, they  are using the term that they “lack belief in God”. They claim that this is different from not believing in God or from saying that God does not exist. I’m not sure how to respond to this. It seems to me that its a silly word-play and is logically the same as saying that you do not believe in God.
What would be a good response to this?
Thank you for your time,

Steven

And here is Dr. Craig’s full response:

Your atheist friends are right that there is an important logical difference between believing that there is no God and not believing that there is a God.  Compare my saying, “I believe that there is no gold on Mars” with my saying “I do not believe that there is gold on Mars.”   If I have no opinion on the matter, then I do not believe that there is gold on Mars, and I do not believe that there is no gold on Mars.  There’s a difference between saying, “I do not believe (p)” and “I believe (not-p).”   Logically where you place the negation makes a world of difference.

But where your atheist friends err is in claiming that atheism involves only not believing that there is a God rather than believing that there is no God.

There’s a history behind this.  Certain atheists in the mid-twentieth century were promoting the so-called “presumption of atheism.” At face value, this would appear to be the claim that in the absence of evidence for the existence of God, we should presume that God does not exist.  Atheism is a sort of default position, and the theist bears a special burden of proof with regard to his belief that God exists.

So understood, such an alleged presumption is clearly mistaken.  For the assertion that “There is no God” is just as much a claim to knowledge as is the assertion that “There is a God.”  Therefore, the former assertion requires justification just as the latter does.  It is the agnostic who makes no knowledge claim at all with respect to God’s existence.  He confesses that he doesn’t know whether there is a God or whether there is no God.

But when you look more closely at how protagonists of the presumption of atheism used the term “atheist,” you discover that they were defining the word in a non-standard way, synonymous with “non-theist.”  So understood the term would encompass agnostics and traditional atheists, along with those who think the question meaningless (verificationists).  As Antony Flew confesses,

the word ‘atheist’ has in the present context to be construed in an unusual way.  Nowadays it is normally taken to mean someone who explicitly denies the existence . . . of God . . . But here it has to be understood not positively but negatively, with the originally Greek prefix ‘a-’ being read in this same way in ‘atheist’ as it customarily is in . . . words as ‘amoral’ . . . . In this interpretation an atheist becomes not someone who positively asserts the non-existence of God, but someone who is simply not a theist. (A Companion to Philosophy of Religion, ed. Philip Quinn and Charles Taliaferro [Oxford:  Blackwell, 1997], s.v. “The Presumption of Atheism,” by Antony Flew)

Such a re-definition of the word “atheist” trivializes the claim of the presumption of atheism, for on this definition, atheism ceases to be a view.  It is merely a psychological state which is shared by people who hold various views or no view at all.  On this re-definition, even babies, who hold no opinion at all on the matter, count as atheists!  In fact, our cat Muff counts as an atheist on this definition, since she has (to my knowledge) no belief in God.

One would still require justification in order to know either that God exists or that He does not exist, which is the question we’re really interested in.

So why, you might wonder, would atheists be anxious to so trivialize their position?  Here I agree with you that a deceptive game is being played by many atheists.  If atheism is taken to be a view, namely the view that there is no God, then atheists must shoulder their share of the burden of proof to support this view.  But many atheists admit freely that they cannot sustain such a burden of proof.  So they try to shirk their epistemic responsibility by re-defining atheism so that it is no longer a view but just a psychological condition which as such makes no assertions.  They are really closet agnostics who want to claim the mantle of atheism without shouldering its responsibilities.

This is disingenuous and still leaves us asking, “So is there a God or not?”

So there you have it. We are interested in what both sides know and what reasons and evidence they have to justify their claim to know. We are interested in talking to people who make claims about objective reality, not about themselves, and who then go on to give reasons and evidence to support their claims about objective reality. There are atheists out there that do make an objective claim that God does not exist, and then support that claim with arguments and evidence. Those are good atheists, and we should engage in rational conversations with them. But clearly there are some atheists who are not like that. How should we deal with these “subjective atheists”?

Dealing with subjective atheists

How should theists respond to people who just want to talk about their psychological state? Well, my advice is to avoid them. They are approaching religion irrationally and non-cognitively – like the person who enters a physics class and says “I lack a belief in the gravitational force!”.  When you engage in serious discussions with people about God’s existence, you only care about what people know and what they can show to be true. We don’t care about a person’s psychology.

Dealing with persistent subjective atheists

What happens when you explain all of that to a subjective atheist who continues to insist that you listen to them repeat over and over “I lack a belief in God, I lack a belief in God”? What if you tell them to make the claim that God does not exist, and then support it with arguments and evidence, but instead they keep leaving comments on your blog telling you again and again about their subjective state of mind: “I lack a belief in cupcakes! I lack a belief in icebergs!” What if they keep e-mailing you and threatening to expose you on Twitter for refusing to listen to them, or denounce you via skywriting: “Wintery Knight won’t listen to me! I lack a belief in crickets!”. I think at this point you have to give up and stop talking to such a person.

And that’s why I moderate and filter comments on this blog. There are uneducated people out there with access to the Internet who want attention, but I am not obligated to give it to them. And neither are you. We are not obligated to listen to abusive people who don’t know what they are talking about. I do post comments from objective atheists who make factual claims about the objective world, and who support those claims with arguments and evidence. I am not obligated to post comments from people who refuse to make objective claims or who refuse to support objective claims with arguments and evidence. And I’m not obligated to engage in discussions with them, either.

UPDATE: I noticed that Reasons for God has a post up about this.
