John Lennox and Paul Davies discuss 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.

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

Psychologist recommends Darwinian storytelling to suppress design intuitions

Amy Hall of Stand to Reason linked to this post by David Klinghoffer on Evolution News.

Excerpt:

The Wall Street Journal salutes the research of Boston University psychologist Deborah Kelemen. She has discovered that it’s possible with Darwinian storytelling to suppress common sense in children of the kind that leads them to recognize artifacts of intelligent design in nature.

The Journal notes that quite apart from religious instruction, kids are primed to see life as reflecting “intentional design.” It’s intuitive. The corrective is to catch them at an early age and train them to see things in a Darwinian light.

By elementary-school age, children start to invoke an ultimate God-like designer to explain the complexity of the world around them — even children brought up as atheists. Kids aged 6 to 10 have developed their own coherent “folk biological” theories. …

Dr. Kelemen and her colleagues thought that they might be able to get young children to understand the mechanism of natural selection before the alternative intentional-design theory had become too entrenched. They gave 5- to 8-year-olds 10-page picture books that illustrated an example of natural selection. The “pilosas,” for example, are fictional mammals who eat insects. Some of them had thick trunks, and some had thin ones. A sudden change in the climate drove the insects into narrow underground tunnels. The thin-trunked pilosas could still eat the insects, but the ones with thick trunks died. So the next generation all had thin trunks.

Before the children heard the story, the experimenters asked them to explain why a different group of fictional animals had a particular trait. Most of the children gave explanations based on intentional design. But after the children heard the story, they answered similar questions very differently: They had genuinely begun to understand evolution by natural selection. That understanding persisted when the experimenters went back three months later.

One picture book, of course, won’t solve all the problems of science education. But these results do suggest that simple story books like these could be powerful intellectual tools. The secret may be to reach children with the right theory before the wrong one is too firmly in place.

There are a number of interesting points here. First, that the example of natural selection is fictional. The mammalian order Pilosa (anteaters and sloths) is real, but “pilosas” are not. Second, it is decidedly in the micro-evolutionary realm — a kind of evolution that no one disputes, certainly not advocates of the theory of intelligent design. There’s no reason to think that the “pilosas” are on their way to true speciation, of the kind that evolutionary theory is really challenged to account for, any more than Darwin’s finches. The extrapolation from such a trivial thing into the origin of all species and all biological complexity by unguided natural processes is a cheat.

Most enlightening is that Dr. Kelemen and her colleagues would, to begin with, seek to talk children out of their intuitive response. Among ID researchers, the approach would be to test that intuition, objectively weighing the empirical evidence without preconceptions. Dr. Kelemen would “suppress” it: her own word!

The abstract of her research publication calls the Darwinian storytelling “interventions”. 

I do think it’s important for parents to counter what these educators are interested in doing to their children.

First, it’s important for parents to consider whether teachers are paid for their work (by parents who use privates schools) or whether their salary is coming from the government (parents are forced by law to pay taxes for government-run “public” schools), which has other purposes for children than parents have.  Second, it’s important for parents to decide how they intend to explain to their children the difference between macroevolution and microevolution, lest naturalistic educators use evidence for microevolution as a way of persuading children to accept macroevolution. Third, parents have to decide how to teach their children about the the standard cosmology, cosmic fine-tuning, the origin of life and the Cambrian explosion – each of which is lethal to naturalism, and each of which is more rooted in experimental science than clumsy storytelling. Unfortunately, the good evidence that modern science offers is largely unknown to most parents, who still trust teachers to teach children truth and practical skills.

I do think it’s important for parents to have some sort of plan for dealing with this, and money to fund their plan. The BU professor is obviously not capable of winning an argument about Darwinism with a grown-up with a good knowledge of the facts, but that’s not her purpose. She is a psychologist in Boston – it’s unlikely she is familiar with actual experimental science related to origins. She’s not interested in debating William Lane Craig or Stephen C. Meyer – she’s never even heard of them. She doesn’t want to talk about the details of experimental science with someone who has an awareness of it, she just wants to pass her own religion (naturalism) on to your children when they are too young to know how to resist her. And I’m sure that she’d like the assistance of a secular government to accomplish that. And believe me, there are powerful people who are very interested in helping her, and in making sure that no parent can stop her from indoctrinating their children.

Why are young evangelicals reluctant to defend Biblical Christianity in public?

Here’s an interesting post by Mark Tooley in the American Spectator.

Excerpt:

A new generation of evangelical elites is imploring evangelicals to step back from the culture wars. Mostly they want to escape polarizing strong stances on same-sex marriage and abortion, and perhaps also contentious church-state issues, like the Obamacare contraceptive mandate.

Purportedly the evangelical church is failing to reach young, upwardly mobile professionals because evangelicals, who now broadly comprise perhaps one third of all Americans, are seen as reactionary and hateful. On their college campuses, at their coffee shops, and in their yoga classes, among other venues, some outspoken hip young evangelicals want a new public image for their faith.

[…]A popular young evangelical blogger echoing Merritt’s theme is Rachel Evans, who conveniently grew up in the Tennessee small town famous for the Scopes Monkey Trial. Her 2010 book was Evolving in Monkey Town: How a Girl Who Knew All the Answers Learned to Ask the Questions. “We are tired of the culture wars,” she explained in a recent interview. “We are tired of politics.” Lamenting the church’s preoccupation with “shame and guilt,” she urged evangelicals to reconsider their opposition to same-sex unions.

The post has a nice history of how evangelicals have always been involved in moral and political issues, and it’s worth reading. But I want to make a different point below.

Compartmentalization of faith

What’s at the root of this movement to back away from moral issues? Here’s what I think is the problem. When you advocate for moral causes like protecting the unborn, or school choice, or freeing the slaves, a bunch of people are not going to like you. Christians in the time of Jesus knew that being bold about their Christian convictions would make a lot of people think bad things about them – they expected it. But young evangelicals have gotten the idea that being a Christian should not involve any sort of unhappiness and unpopularity. They wouldn’t have learned this from the Bible, because the Bible emphasizes suffering and unpopularity as part of the normal Christian life. It is their experience of church (and the hedonistic culture around them) that is likely to reinforce that view.

What young evangelicals learn in many churches is that religion is something that is centered on the Bible and the church building – it is not something that flows into real life. They learn that you can’t find out anything about God from the Big Bang, the DNA, the fossil record, or even from the peer-reviewed research on abortion, divorce, or gay marriage. They learn from the Bible that helping the poor is good, but then they never pick up an economic textbook to see which economic system really helps the poor. What you learn about in church is that religion is private and has no connection to reality whatsoever. This fits in with their view that Christianity should make them happy, because they’ve learned that it doesn’t involve any studying to connect the Bible to the real world.

What follows from having a view that Christianity only lives in the Bible and church, and not out there in the real world of telescopes and microscopes? Well, most young evangelicals interpret what their pastor is telling them as “our flavor of ice cream” or “our cultural preference”. They don’t link Christianity to the real world, they don’t think that it’s true for everyone. They think that you just accept what the Bible says on faith, and that’s all. No reasons can be given to non-Christians outside of just asking them to accept the Bible. Younger evangelicals believe that there are no facts that confirm or disprove Christianity – it’s just a blind belief. Young evangelicals think that their faith doesn’t have to be complemented with careful study of how things work in the real world.

What is the result of this anti-intellectual compartmentalization of faith? The result is that young evangelicals will balk at the idea of telling someone that they are going to Hell if they don’t believe in Jesus. They will balk at the idea that feminism is to blame for the destruction of the family. They will balk at the idea that the best way to help the poor is to push for free market capitalism. They will balk at the idea that it is wrong to kill unborn children. They will balk at the idea that disarmament and pacifism embolden terrorists and tyrants to attack peace-loving people. They will balk at the idea that traditional marriage is better for society and children. They will balk at the idea that man-made catastrophic global warming is not supported by science. They lack courage to take Biblical positions, because they first lack knowledge. They don’t know how to make the case using evidence that their opponents will accept – mainstream evidence from publicly accessible sources.

Christianity is a knowledge tradition

If the purpose of religion is to have happy feelings and be liked, then studying the real world to find out whether the Bible is true is bad religion. If religion is divorced from reality, then it’s just a personal preference influenced by how a person was raised. No young evangelical is going to lift a finger to take bold moral stands if they think their worldview is just one option among many – like the flavors of ice cream in the frozen section of the grocery store. They have to know that what they are saying is true – then they will be bold. An example: there was a time when people believed that God did not create the first living cell, because it was just a simple lump of protoplasm that could easily come about by accident. Now we know better, and we can boldly make the case for intelligent design based on hard evidence – if we put in the time to study the evidence.

And it is the same for everything – from theological claims, to moral claims, to social claims, to economic claims, to foreign policy claims. It doesn’t matter if people call you names when you have the facts to support unpopular claims, and that’s why public, authentic Christianity is built on knowledge of facts. Non-Christians being offended by your claims doesn’t change the way the world is.
