Is belief in God explained by chemicals in the brain?

Greg Koukl of Stand to Reason explains. (H/T Melissa)

As Greg often says, before you can show WHY a belief is false, you know to show THAT a belief is false.

For those of us who are stuck behind a firewall, you can read this article by Paul Copan instead.

Here’s the problem:

Evolutionary biologist Richard Dawkins suggests that our “extraordinary predisposition” to “insist on believing in God” is that we, like computers, tend to do what we’re told. Young minds are susceptible to “infection” and mental “viruses” especially when they latch on to the bad or worthless religious ideas of charismatic preachers and other adults.1 Anthropologist Pascal Boyer believes that the latest “scientific” developments reveal that our “central metaphysical urge”—an “irredeemable human propensity toward superstition, myth and faith, or a special emotion that only religion provides”2 stands at the root of all religion. Author Matthew Alper considers humans to be religious animals whose brains are hard-wired for “God,” though no God exists, and maintains that the “spiritual” is really the “scientific.”3

And here’s the solution:

To say God doesn’t exist because people believe for inferior reasons or motivations is to commit the genetic fallacy—to say that a view is true/false based on its origin. God’s existence, however, is logically independent of how people come to believe in Him.

Consider the strong reasons for God’s existence distinct from human hard-wiring and psychology. The existence of valuable, morally responsible, self-aware, reasoning, living human beings who inhabit a finely tuned universe that came to exist a finite time ago is not plausibly explained naturalistically—namely, as the result of disparate valueless, mindless, lifeless physical processes in a universe that came into existence uncaused out of nothing. The better unifying explanation is a supremely valuable, supremely aware, reasoning, truthful, powerful, intelligent, beautiful Being. Such a context robustly explains—and unifies—a wide range of factors where naturalism fails. If God exists and leaves clues of his existence, then CSR’s reductionistic claims about theistic belief lose their force.

There is a LOT more in the Paul Copan essay on cognitive science of religion (CSR).

And Michael Murray published a book with Oxford University Press on his solution to this problem.

Excerpt:

Critics argue that belief in God is unwarranted because it arises from evolved, hard-wired cognitive mechanism. But, if these psychologists are right, so are many (if not all) of our other beliefs.

“Surely the critic doesn’t want to say that any belief that is the output of our mental tools—our cognitive tools—is unwarranted,” Murray notes, because “we can’t reasonably think that all of our beliefs are unreliable.” Further,

most of these critics think that our cognitive tools usually get things just right. To see this, just substitute the following words (or phrases) into the argument [above] and see if the critic would still find the underlying reasoning acceptable: human minds, rocks, rainbow, or science’s ability to discover the truth.

In other words, “Why do they think it’s fair to single out belief in the existence of God as the one thing that turns out to be unreliable or unwarranted?”

Hence, Murray notes, this sweeping argument is self-defeating. For if all brain-dependent beliefs are unwarranted, then the idea that “belief in God is unwarranted” is itself unwarranted.

Dawkins and many of his peers think this argument shows belief in God to be “merely” a “by-product” of human evolutionary development. Theistic intellectuals like Murray conclude that “God instead, designed us so that belief in him is easy and natural. The human mind is naturally constructed in such a way that we have a tendency to form beliefs in God concepts, and even of a somewhat specific sort.”

So if you believe Koukl, the argument commits the genetic fallacy. But even if you allow it to go through, like Michael Murray does, it’s self-refuting. (You can read more about Murray’s views in “Contending With Christianity’s Critics” and “Passionate Conviction” – and don’t worry about chastising him about his moderate views of intelligent design, I already wrote to him and beat him up about that, and he said it was just a bias / preference he had against intervening acts of fine-tuning subsequent to the moment of creation).

MUST-HEAR: John Lennox and Paul Davies debate about aliens and the origin of life

An amazing debate about the origin of life and the cosmic fine-tuning between a Christian and a materialist agnostic. John Lennox is AWESOME in this debate, and he only talks for a tiny part of the debate. He’s very gracious, and focused the discussion on the areas that we care about. Paul Davies is an EXCELLENT scientist and well aware of what Christians believe. This is a great debate, very easy to listen to. Justin, the moderator, does a great job controlling a fantastic discussion.

The MP3 file is here.

Details

What does it take for life to get going in our universe? Is there intelligence in the stars or right under our nose? Renowned astrophysicist Paul Davies chats to Oxford Professor of Mathematics John Lennox.

A popular science author, Davies is also the Chair of the SETI post detection task force. His latest book “The Eerie Silence” which marks SETI’s 50th anniversary examines the likelihood of the universe producing life elsewhere.

John Lennox is a Christian Mathematician and philosopher. He is the author of “God’s Undertaker: has science buried God?” and has debated Richard Dawkins on several occasions.

Davies’ work on the fine tuning of the universe for life has been sympathetic to theism. In this programme Lennox challenges Davies to look to design not just in cosmology but in the cell. They also chat about what the discovery of ET would mean for Christian theology.

Summary

Justin:

  • Is there meaning in the universe?

Paul:

  • We have no evidence for or against intelligent life elsewhere in the universe
  • The vastness of the universe makes me think there is life elsewhere
  • Humans are capable of observing and understanding the universe
  • It seems the universe has the ability to create observers to understand it
  • If one species has this ability, then we should expect others to do it

John:

  • The fact that we can observe the universe and do science has cosmic significance
  • Our rare habitable planet and our ability to do science is suggestive of purpose
  • So science itself points to an extra-terrestrial intelligence: GOD
  • The complexity of life and consciousness itself points away from atheism
  • Monotheism gave birth to science
  • Human minds capable of doing science are not compatible with atheistic materialism

Justin:

  • Why do you say that either we are the only life or there are many different kinds of life?

Paul:

  • There are lots of factors that have to be met to have a site for simple life
  • These are related to the fine-tuning of cosmic constants, e.g. gravitational force
  • But there are also factors that have to be met for originating intelligent life
  • Things like convergence, self-organization, etc.
  • So the cosmic requirements and evolutionary requirements are different
  • Darwinian evolution doesn’t solve the problem of the origin of life
  • 50 years ago, skepticism about alien life existing anywhere was excessive
  • Today, credulity about alien life exiting everywhere is excessive
  • The naturalist is searching for a process that creates life easily

John:

  • Paul agrees that there is no theory for a naturalistic origin of life
  • This is fatal for the idea that life can emerge elsewhere in the universe
  • We have not discovered any law that produces life without an intelligence
  • Consider the method used by SETI used to detect an alien intelligence
  • Why can’t this method be applied to the origin of life on Earth?
  • Why can’t an intelligence created specified complexity (functional information)?
  • Why can’t an intelligence created epigenetics and protein folding?

Paul:

  • Darwinian evolution can add new biological information after life begins

John:

  • Darwinian evolution assumes a mutating replicating life form to act on

Paul:

  • You can’t generate specified complexity by using physical laws
  • You can’t generate specified complexity by chance
  • At this point we are guessing as to how life might have formed

John:

  • Why do we have to rule out an intelligent cause a priori
  • If you can recognize an intelligence in outer space, why not in living systems?

Paul:

  • I don’t mind the word “intelligence”, it’s the word “signal”
  • I oppose the idea that God or aliens manipulated physical stuff to create life
  • It’s an “ugly explanation and very unappealing both theologically and scientifically”
  • I prefer the idea that the universe has processes to self-organize and create complexity
  • When it comes to supernatural meddling by God, “I don’t want that”
  • If I were God, I would create the universe so that I would not have to intervene
  • I think God would be more clever if he did not have to intervene
  • My preferences about what is “clever” determines what scientific conclusions are allowed

John:

  • Humans already have experience with their non-material minds to move atoms (matter)
  • If God is a mind, then there is no reason why he cannot move atoms (matter)

Paul:

  • My mind is physical, so are you saying that God is physical?
  • If God intervenes in the universe, then what is he doing now?

John:

  • There is a distinction between acts of creation and providential upholding the universe
  • God is also speaking to people and drawing humans toward him
  • God is spirit, not material

Paul:

  • How can a non-physical entity cause effects on the physical world?

John:

  • What science reveals that there is information needed for the origin of life
  • Information requires an intelligence to create it, just as with human who write books
  • That’s not God of the gaps – it’s an inference based on what we know today

Paul:

  • We may be able to explain the origin of life later, using matter, law and chance
  • What you’re saying is that God tinkers with the genome
  • If you say that God intervened once, then he intervenes all the time, everywhere!
  • I don’t want a God who tinkers in the genome
  • if God could intervene in the universe that would remove its intelligibility

John:

  • Look at the cover of this book – when I read words, I infer an intelligence
  • There are bad gaps that the progress of science closes
  • There are good gaps that science opens, showing the need for intelligence
  • On the one hand, you say we have no theory of the origin of life
  • On the other hand, you know that an intelligent designer wasn’t involved
  • If we don’t know how life began, why do you rule God out a priori?

Paul:

  • What scientists want to do is to explain the universe without involving God
  • naturalists want to use science to discover only materialist explanations
  • The purpose of SETI is to prove that there is other life in the universe
  • This would then show that there is a naturalistic way of making life
  • I agree that information in living systems is real hard to explain materialistically
  • I believe in the power of emergence
  • We might discover laws that prove that complexity can emerge without intelligence
  • The discovery of alien life would help to show that no intelligence is needed to make life

Justin:

  • What sort of cosmic fine-tuning is needed at the Big Bang for life to occur?

Paul:

  • It’s true that the universe appears extremely fine-tuned for life to exist
  • The typical answer from naturalists is that there is a multiverse
  • But the multiverse “falls far short” of providing a good answer to the fine-tuning
  • It’s irrational to appeal to massive numbers of unseen universes to explain fine-tuning
  • The design and purpose seen in the universe may be due to God or it may be emergent

John:

  • The fine-tuning is real and the multiverse is a desperate attempt to evade the creator
  • Sir Martin Rees (an atheist) says he “prefers” the multiverse to a designer
  • Scientists are not supposed to prefer anything except what is true

Justin:

  • Would the discovery of aliens hurt Christianity, because of the belief in the uniqueness of humans?

Paul:

  • Christians believe that Jesus came to save HUMANS specifically, not animals or aliens
  • If we were to discover intelligent aliens, it would challenge traditional religions
  • What will God do with alien races? Multiple incarnations? Or just preach the gospel to them?

John:

  • We don’t know if the aliens exist, first of all – it’s speculative
  • The Bible teaches that humans bear the image of God
  • We just don’t know whether alien species are also made in God’s image

MUST-READ: J.P. Moreland’s argument for theism from consciousness

Here’s a post from Thinking Matters New Zealand.

Excerpt:

Last year, the release of J. P. Moreland and William Lane Craig’s Blackwell Companion to Natural Theology saw a lot of attention. And quite rightly. The Companion marshalled some of most cutting-edge work in the field of the philosophy of religion and showed why natural theology is fast becoming an exciting scholarly domain again. But in the shadow of the Companion’s release, another of Moreland’s works was published: The Recalcitrant Imago Dei: Human Persons and the Failure of Naturalism. Although it might not have got the same amount of attention, The Recalcitrant Imago Dei also represented an important entry in the contest of ideas and a powerful defense of theism. In it, Moreland argues for the theistic position by way of a stinging attack on naturalism and its failure to answer the problem of consciousness and account for the basic facts of human experience, such as free will, rationality, and intrinsic value.

And here’s the formal argument:

1. Genuinely non-physical mental states exist.

2. There is an explanation for the existence of mental states.

3. Personal explanation is different from natural scientific explanation.

4. The explanation for the existence of mental states is either a personal or natural scientific explanation.

5. The explanation is not a natural scientific one.

Therefore

6. The explanation is a personal one.

7. If the explanation is personal, then it is theistic.

Therefore

8. The explanation [for the existence of mental states] is theistic.

That’s the argument. Each of the premises needs to be more likely than not for the argument to go through. And you can read about how each premise is supported in this helpful post from Bill Vallicella at Prosblogion. This is good little argument to ad to your quiver of scientific arguments. I think this argument and moral argument are two nice little philosophical arguments that show that theism is the necessary starting point for morality and rationality. Particles in motion will not do the job.

I actually learned about this argument by reading chapter 3 of “Scaling the Secular City”, and listening to J.P. Moreland lectures. If you want to learn about this argument in a lecture, try this one. This is one of my favorite lectures. It was delivered at the University of Georgia. That’s the one I use when I’m training this argument, along with his lecture on “The Invisible Man” for Stand to Reason’s Masters Series, which is also good. Moreland also does public debates.

I notice that the new book mentioned above is quite expensive, and you’d be better off buying “Body and Soul” and “Philosophical Foundations for a  Christian Worldview”. SPCK is an academic press and so their books are very expensive, compared to IVP.
