Note: there is a period of 19 minutes of Q&A at the end of the lecture.

About the speaker:

His full biography is here.

Summary:

  • It used to be true that most of the great scientists were believers in God
  • But now science has advanced and we have better instruments – is it still true?
  • Today, many people believe that science has shows that the universe and Earth are not special
  • We used to believe that the Earth was the center of the universe, and Darwin showed we are not designed
  • The problem with this view is that it is based on old science, not modern science
  • Three topics: origin of the universe, fine-tuning of the universe, the Rare Earth hypothesis

Experimental evidence for the origin of the universe:

  • #1: Hubble discovered that the universe expands because of redshifting of light from distant galaxies
  • #2: Measurements of the cosmic microwave background radiation show the universe had a beginnning
  • #3: Measurements of the light element (hydrogen and helium) abundances confirm an origin of the universe
  • The best explanation for an absolute origin of space, time, matter and energy is a supernatural cause

Experimental evidence for the design of the universe:

  • #1: The amount of matter: a bit less = no stars and galaxies, a bit more = universe recollapses
  • #2: The strong force: a bit more = only hydrogen, a bit more = little or no hydrogen
  • #3: Carbon resonance level: a bit higher = no carbon, a bit lower = no carbon

Experimental evidence for galactic, stellar and planetary habitability:

  • #1: Galaxy: produces high number of heavy elements and low radiation
  • #2: Star: long stable lifetime, burns bright, bachelor star, third generation star (10 billion years must elapsed),
  • #3: Planet: mass of planet, stable orbit, liquid water, tectonic activity, tilt, moon

Naturalistic explanations:

  • Humans evolve to the point where they reach back in time and create finely-tuned universe
  • Eternally existing multiverse

Hawking and Mlodinow response to Rare Earth:

  • There are lots of planets so one must support life
  • Odds of a planet that supports life are low even with 10^22 planets

Hawking and Mlodinow proposal of M-theory multiverse:

  • There is no experimental evidence for M-theory being true
  • M-theory is not testable now and is not likely to be testable in the future
  • But science is about making testable predictions, not about blind speculation

Hawking and Mlodinow no-boundary proposal:

  • This theory requires the laws of physics to exist prior to the universe
  • But where do you get laws of physics before there is any physical world?
  • There is no experimental evidence for no-boundary proposal
  • All the evidence we have now (redshift, CMBR, H-He abundances) is for Big Bang

What science has revealed provide abundant evidence for a transcendent Creator and Designer

Cosmologist Luke Barnes answers 11 objections to the fine-tuning argument

Apologetics and the progress of science
Apologetics and the progress of science

This is from the blog Common Sense Atheism. (H/T Allen Hainline)

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 what was in the podcast. (I wish more people who put out podcasts would do that).

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:

  1. “It’s just a coincidence.”
  2. “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!”
  3. “However the universe was configured, evolution would have eventually found a way.”
  4. “There could be other forms of life.”
  5. “It’s impossible for life to observe a universe not fine-tuned for life.”
  6. “Maybe there are deeper laws; the universe must be this way, even though it looks like it could be other ways.”
  7. “Maybe there are bajillions of universes, and we happen to be in one of the few that supports life.”
  8. “Maybe a physics student in another universe created our universe in an attempt to design a universe that would evolve intelligent life.”
  9. “This universe with intelligent life is just as unlikely as any other universe, so what’s the big deal?”
  10. “The universe doesn’t look like it was designed for life, but rather for empty space or maybe black holes.”
  11. “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.

New study: belief in free will linked to ability to behave morally and to help others

J. Warner Wallace: God's Crime Scene
J. Warner Wallace: God’s Crime Scene

So, Monday night I finally finished “reading” God’s Crime Scene, the new book by J. Warner Wallace. I was listening to the audio book, because it is hard to speed along with the top down and read at the same time. For now, here’s my one line review: this is a book for people who like evidence – he has collected a ton of evidence on everything people should be puzzling about, and sometimes on surprising topics. Anyway, I wanted to post something about some studies he mentioned in Chapter 6, on free will. This is one of the places where he found evidence in a surprising area.

Wallace says that free will makes more sense if theism is true, because we have non-material souls that interact with our bodies, but are not causally determined by them. On atheism, only matter exists, and you can’t get free will (or consciousness) from matter. So atheists like Sam Harris and Alex Rosenberg, for example, deny free will, because they are materialists and atheists.

Anyway, here’s what he writes on p. 256:

In 2008, researchers from the University of Minnesota and the University of British Columbia conducted experiments highlighting the relationship between a belief in determinism and immoral behavior. They found students who were exposed to deterministic literature prior to taking a test were more likely to cheat on the test than students who were not exposed to literature advocating determinism. The researchers concluded those who deny free will are more inclined to believe their efforts to act morally are futile and are, therefore, less likely to do so.

In addition, a study conducted by researchers from Florida State University and the University of Kentucky found participants who were exposed to deterministic literature were more likely to act aggressively and less likely to be helpful toward others.” Even determinist Michael Gazzaniga conceded: “It seems that not only do we believe we control our actions, but it is good for everyone to believe it.”” The existence of free will is a common characteristic of our experience, and when we deny we have this sort of free agency, there are detrimental consequences.

I decided to look up these studies.

Here’s the abstract for first study: (2008)

Does moral behavior draw on a belief in free will? Two experiments examined whether inducing participants to believe that human behavior is predetermined would encourage cheating. In Experiment 1, participants read either text that encouraged a belief in determinism (i.e., that portrayed behavior as the consequence of environmental and genetic factors) or neutral text. Exposure to the deterministic message increased cheating on a task in which participants could passively allow a flawed computer program to reveal answers to mathematical problems that they had been instructed to solve themselves. Moreover, increased cheating behavior was mediated by decreased belief in free will. In Experiment 2, participants who read deterministic statements cheated by overpaying themselves for performance on a cognitive task; participants who read statements endorsing free will did not. These findings suggest that the debate over free will has societal, as well as scientific and theoretical, implications.

And the abstract for the second study: (2009)

Laypersons’ belief in free will may foster a sense of thoughtful reflection and willingness to exert energy, thereby promoting helpfulness and reducing aggression, and so disbelief in free will may make behavior more reliant on selfish, automatic impulses and therefore less socially desirable. Three studies tested the hypothesis that disbelief in free will would be linked with decreased helping and increased aggression. In Experiment 1, induced disbelief in free will reduced willingness to help others. Experiment 2 showed that chronic disbelief in free will was associated with reduced helping behavior. In Experiment 3, participants induced disbelief in free will caused participants to act more aggressively than others. Although the findings do not speak to the existence of free will, the current results suggest that disbelief in free will reduces helping and increases aggression.

So what to make of this?

If you’re an atheist, then your worldview is telling you that what you are doing now is the result of genetic programming and sensory inputs. You’re not conscious. You can’t reason. You make no free choices, including moral choices. Naturally, someone who believes this is going to struggle with prescriptive morality, including self-sacrificial care and concern for others. Their worldview undermines the rationality of the moral point of view. You might find atheists acting morally for their own purposes, but their worldview doesn’t rationally ground it. This is a big problem for people who can see objective morality woven into the universe – and themselves – because they have the awareness of objective right and wrong.

I think what atheists like to say is “I can be moral, too”. That’s not interesting. What is interesting is whether it is rational for you to be moral when things start to get a bit uncomfortable. When I look at the adultery of Dawkins, the polyamory of Carrier, the divorces of Shermer and Atkins, etc. I am not seeing anything that really wows me. They all deny free will of course, and think that trying to resist temptation is a waste of time. What difference would it make if they did, anyway – there’s no afterlife on atheism.

Wallace explains how the awareness of free will and moral choices caused him to turn away from atheism, in this blog post.

He writes:

As an atheist, I chose to cling to naturalism, in spite of the fact that I lived each day as though I was capable of using my mind to make moral choices based on more than my own opinion. In addition, I sought meaning and purpose beyond my own hedonistic preferences, as though meaning was to be discovered, rather than created. I called myself a naturalist while embracing three characteristics of reality that simply cannot be explained by naturalism. As a Christian, I’m now able to acknowledge the “grounding” for these features of reality. My philosophical worldview is consistent with my practical experience of the world.

I think atheists who want to be honest about their own experience of first-person consciousness, free will, moral realism, etc. will do well to just accept that theism rationally grounds all of these things, and so you should accept theism. Theism is real. If you like morality, and want to be a virtuous person, then you should accept theism.
