Polemics

Ed Feser takes on Lawrence Krauss and Victor Stenger

3 Comments

From Ed Feser’s blog. (H/T Chris R.)

Excerpt:

I recently linked to philosopher of physics David Albert’s take down of Lawrence Krauss’s bookA Universe From Nothing.  (My own review of Krauss will soon appear in First Things.)  A reader calls my attention to this blog post in which Victor Stenger — Adjunct Professor of Philosophy at the University of Colorado, Professor Emeritus of Physics and Astronomy at the University of Hawaii, and author of several atheist tomes — rides to the rescue of Krauss against Albert.  (If only the other philosophically incompetent New Atheists had such a knight in shining armor!  O Dawkins, where is your Stenger?  O Coyne, where is your Victor?)

Unfortunately for Krauss, the intrepid Stenger shoots only blanks.  And misses.  Krauss, as you may know, argues that the laws of quantum mechanics (QM) show how a universe can arise from nothing.  Albert demurs, and Stenger responds:

[Albert] asks, “Where, for starters, are the laws of quantum mechanics themselves supposed to have come from?”  Krauss admits he does not know, but suggests they may arise randomly, in which case some universe like ours would have arisen without a prescribed cause.  In my 2006 book The Comprehensible Cosmos, I attempt to show that the laws of physics arise naturally from the symmetries of the void.

Later Stenger tells us that the “void” or “nothing” in question “can be described mathematically,” “has an explicit wave function,” and “is the quantum gravity equivalent of the quantum vacuum in quantum field theory.”

Of course, the problem with all of this is the same as the problem with the original suggestion that the laws of QM show that a universe can come from nothing.  The laws of QM are not nothing, and neither are “the symmetries of the void” nor anything that “can be described mathematically,” “has an explicit wave function,” etc.  In general, if you can characterize it in terms of physical law — which Krauss, Stenger, and like-minded atheists all want to do vis-à-vis “nothing” — then it isn’t nothing.  It’s something physical, and thussomething rather than nothing.  Obviously.

Obviously, that is, unless you are a New Atheist dogmatically attached to the utterly groundless proposition that all genuine questions simply must be susceptible of a scientific answer.  At this juncture Stenger does what an increasing number of atheists do when it is pointed out to them that their “explanations” of how the universe arose from nothing merely change the subject — they feign ignorance of English.  Writes Stenger:

Clearly, no academic consensus exists on how to define “nothing.”  It may be impossible.  To define “nothing” you have to give it some defining property, but, then, if it has a property it is not nothing!

But this is the muddleheaded stuff of a freshman philosophy paper — treating “nothing” as if it were an especially unusual, ethereal kind of substance whose nature it would require tremendous intellectual effort to fathom.  Which, as everyone knows until he finds he has a motive for suggesting otherwise, it is not.  Nothing is nothing so fancy as that.  It is just the absence of anything, that’s all.  Consider all the true existential claims that there are: “Stones exist,” “”Trees exist,” “Quarks exist,” etc.  To ask why there is something rather than nothing is just to ask why it isn’t the case that all of these statements are false.  Pretty straightforward.

To admit the obvious, though, would be to admit that there are questions that physics cannot answer, such as where the laws of physics themselves came from — or more precisely, since “laws” are just abstractions from a concrete physical reality that behaves in accordance with the laws, where this concrete physical reality itself comes from.  That nothing in physics answers this question was Albert’s point, and Stenger says absolutely nothing to answer it.

Read the rest. It’s really good! and there’s a lot more goodness there. 176 comments at the time I am writing this.

UPDATE: Peter Sean Bradley note that Krauss is now walking back his rhetoric in response to criticisms from people like atheist John Horgan.

I have been writing about Stenger and Krauss a lot lately, so here are the links in case you missed anything:

William Lane Craig debates Lawrence Krauss: Does God Exist?

3 Comments

Audio of the William Lane Craig vs. Lawrence Krauss debate at North Carolina State University has now been posted at Apologetics 315.

And I also posted some background information on Craig’s arguments.

William Lane Craig’s case

William Lane Craig made 5 arguments for the existence of God:

  • the contingency argument
  • theargument from the origin of the universe (kalam)
  • the argument from cosmic fine-tuning
  • the moral argument
  • the argument from the miracle of the resurrection

These arguments went unrefuted during the debate.

Lawrence Krauss’s case

Lawrence Krauss made the following arguments in his first speech:

  • Dr. Craig is a professional debater
  • Dr. Craig is not a scientist
  • Dr. Craig is a philosopher
  • Disproving God’s is a waste of my valuable time
  • Dr. Craig has the burden of proof to show evidence
  • My job is not to present any evidence
  • I think that “extraordinary claims require extraordinary evidence” is a nice slogan, but I have no evidence for it
  • I don’t like that God doesn’t appear on Youtube, therefore he doesn’t exist
  • I don’t like that God didn’t appear to humans until recently, therefore he doesn’t exist
  • I don’t like that the stars didn’t come together to spell “I am here”, therefore God doesn’t exist
  • Dr. Craig has to supply extraordinary evidence, because my favorite slogan says he has to
  • Dr. Craig talks about logic, but the universe is not logical
  • Dr. Craig doesn’t have any arguments, just things he doesn’t like
  • Dr. Craig doesn’t like infinity, and that’s why he believes in the Big Bang cosmology
  • Dr. Craig doesn’t like chance, and that’s why he believes in cosmic fine-tuning
  • Dr. Craig doesn’t like rape, and that’s why he believes in the ontological foundations of morality
  • If people believe in logic, then they can’t do science
  • The things that science discovers contradict the laws of logic
  • For example, Dr. Craig doesn’t like infinity, so he believes in the experimental measurements of the cosmic microwave background radiation
  • For example, Dr. Craig doesn’t like chance, so he believes in the fine-tuning of the gravitational constant for the formation of stable stars
  • Quantum mechanics shows that the universe is stranger than you think, therefore all of Craig’s arguments are false
  • My t-shirt says 2 + 2 = 5, therefore all of Craig’s arguments are false
  • Atheism may look ridiculous, but it’s true, and if you don’t like it, too bad – because the universe is very strange
  • Accidents happen all the time, so that explains the cosmic fine-tuning
  • We all have to convince ourselves of 10 impossible things before breakfast, and atheism is impossible, so you need to convince yourself of it
  • I don’t know about the Big Bang, so Dr. Craig cannot use the Big Bang to to prove the universe began to exist
  • I don’t know about the cosmic fine-tuning, so Dr. Craig cannot use the fine-tuning of cosmological constants to prove the fine-tuning
  • I don’t know anything about science, so Dr. Craig cannot use science in his arguments
  • Dr. Craig says that the universe is contingent because it began to exist 13.7 billion years ago based on the state-of-the-art scientific evidence for the Big Bang creation out of nothing from 1) red-shift of light from distant galaxies, 2) cosmic microwave background radiation, 3) helium-hydrogen abundances, 4) experimental confirmation of general relativity, 5) the second law of thermodynamics, 6) radioactive element abundances, etc., but how does he know that? I don’t know that
  • It’s fine not to know the answer to scientific questions like whether the universe began to exist, it’s more exciting
  • Thinking that the universe began to exist based on 6 pieces of scientific evidence is the “God-of-the-Gaps” fallacy, it’s intellectual laziness
  • But all kidding aside, the universe actually did begin to exist 13.72 billion years ago, exactly like Craig says in his argument
  • I could argue that God created the universe 4.5 seconds ago with all of us sitting believing that we heard Dr. Craig, and how could you prove me wrong? It’s not falsifiable
  • Universes can spontaneously appear out of nothing, and in fact they have to appear out of nothing
  • Nothing is unstable, and space and time can come into existence out of nothing, so that’s not a problem
  • Our universe could have appeared out of a multiverse, an unobservable, untestable multiverse that I have no way of observing or testing
  • The universe is not fine-tuned for life, and no scientist says so, especially not Martin Rees, the atheist Astronomer Royal, and every other scientist
  • What if God decided that rape was OK, would it be OK? God can change his moral nature arbitrarily, can’t he?

Here are the arguments in Krauss’ second speech:

  • We don’t understand the beginning of the universe
  • We don’t understand whether the universe had a cause
  • Steven Weinberg says that science makes it possible to be an atheist, so therefore the universe didn’t begin and didn’t have a cause
  • It’s just intellectual laziness to say that the universe came into being 13.7 billion years ago, and that things that come into being of nothing have a cause
  • Dr. Craig is an expert on nothing, ha ha ha!
  • There are multiple versions of nothing, there’s nothing, and then there is something, which is also nothing if I want it to be
  • There was no space, there was no time, and then the space create the empty space
  • I’m going to give Dr. Craig a break
  • At least in the nothing there were laws like F=ma, and those laws created the empty space, because descriptions of matter that does not even exist yet can create space out of nothing
  • Alan Guth and Alexander Vilenkin are good friends of mine and I talk to them all the time, unlike Dr. Craig
  • Alan Guth and Alexander Vilenkin don’t mention God in their scientific papers, therefore the universe didn’t begin and didn’t have a cause
  • Maybe there is a multiverse that cannot be observed or tested? And my unscientific speculations are a refutation of Craig’s scientific evidence for the fine-tuning
  • Dr. Craig just doesn’t like my speculations about the unobservable, untestable multiverse, and that’s why he believes in the Big Bang cosmology
  • And if you let me speculate about an unobservable, untestable multiverse, then maybe the inanimate invisible universes reproduce and compete for food and mutate like animals and then there is natural selection so that the finely-tuned universes survive and now we’re in one!
  • My cool animation of blue goo mutating proves that the multiverse is real! Empty space is not empty!
  • Darwinism, which is a theory about the origin of species, explains the cosmic fine-tuning that occurred at the moment of creation
  • The unobservable, untestable multiverse universes all have different laws, I believe
  • We don’t know what the right answer is, but we are willing to look at any possibility, as long as the possibilities we look at are not supernatural possibilities
  • The discovery of the origin of the universe could be an accident, I don’t know if the universe began to exist or not, maybe all the six scientific evidences are wrong because if I don’t like the evidence we have, so I’ll just wait for new evidence to overturn the evidence we have which I don’t like
  • Maybe there are other forms of life that are unobservable and untestable that are compatible with a universe that has no stable stars, no planets, no elements heavier than hydrogen, no hydrogen, no carbon, etc.

Here are the arguments in Krauss’ third speech:

  • Dr. Craig is stupid
  • Why should we even care about Dr. Craig’s arguments and evidence, we can just count the number of scientists who are atheists and decide whether God exists that way – I decided everything based on what my teachers told me to believe
  • I actually know general relativity, not like Dr. Craig who co-wrote a book on general relativity published by Oxford University Press
  • What quantum mechanics shows is that virtual particles come into being in a quantum vacuum, and then go out of existence almost immediately – and that is exactly like how a 13.7 billion year old universe came into being in a quantum vacuum, and we’re going to disappear very soon
  • Space and the laws of physics can be created, possibly, if you accept my speculations about an unobservable, untestable multiverse
  • I don’t like the God of the Old Testament, therefore he doesn’t exist
  • Groups of people can decide what they think is good and evil, like the Nazis and slave-owners did, and then that becomes good for them in that time and place, and that’s what I mean by morality
  • Here’s something I studied that wasn’t fine-tuned, therefore there is no fine-tuning of the universe
  • Not knowing things is really exciting! Dr. Craig is not really exciting because he knows things – phooey!

Here are the arguments in Krauss’ fourth speech:

  • If you will just grant me an observable, untestable multiverse, then there must be some universe where intelligent life exists
  • Infinite numbers of things exist everywhere in nature, you can see lots of infinite collections of things, like jelly beans and bumblebees and invisible pink unicorns
  • I don’t like the fine-tuning, but if my speculations about the multiverse are proven true, then I won’t have to learn to live with the fine-tuning
  • Inflation, the rapid expansion of the universe which occurs at some time after the the origin of the universe (t = 0), explains the absolute origin of time, space, matter and energy out of nothing that occurred at t = 0
  • Physical processes that develop subsequent to the creation of the universe at t > 0 can explain the fine-tuning of quantities that are set at t = 0
  • Morality is just a bunch of arbitrary conventions decided by groups of people in different times and places by an accidental process of biological and social evolution, but that practice over there by those people is objectively wrong!
  • 1 Cor 15:3-7, which most scholars, even atheists like James Crossley, admit is dated to within 3 years of the death of Jesus, is actually dated to 50 years after the death of Jesus
  • The historical case for the resurrection made by people like N.T. Wright in their multi-volume academic works is on par with the story of Mohammed ascending to Heaven on a horse

Lawrence Krauss debates “A Universe From Nothing” with an astrophysicist

15 Comments

Dina sent me news of Saturday’s episode of Unbelievable, which features Lawrence Krauss, who debated William Lane Craig. Krauss’ book was also reviewed in the New York Times.

The MP3 file is here.

Details:

Lawrence Krauss is a Cosmologist at Arizona State University who describes himself as an “anti-theist”. His latest book “A Universe From Nothing” has received both acclaim and criticism for its attempt to answer the question “Why is there something rather than nothing?” Debating the issue with Krauss is Rodney Holder, Course director at the Faraday Institute, Cambridge. An astrophysicist and priest by background. In a lively exchange they debate whether Krauss’ “nothing” is “nothing”, fine tuning and multiverses, scientific knowledge, miracles and the usefulness of theology and philosophy.

This debate is quite entertaining, and do not be intimidated if your don’t understand science. You can understand pretty easily who is arguing based on facts and who is speculating about unobservable, untestable entities. At one point, Krauss actually denies that there is any fine-tuning in the universe, so please see this link to refute that claim as well as this podcast which explains some examples of fine-tuning. Krauss gets a bit angry at the beginning, but calms down.

Quotation marks are for direct quotes, italics is for made-up snark. See below the summary for more posts that are related to this one.

Summary of the discussion: (picked up at 9:30 when they start talking about the book)

Brierley:

  • explain your theory of how the universe can come into being from nothing

Krauss:

  • the nothing that preceded the universe is “no space, no time, no universe”
  • theists say that God is responsible for creating the universe out of this nothing
  • but the laws of nature can create the universe uncaused out of nothing

Holder:

  • Krauss sometimes writes that the nothing is really a quantum vacuum, but that is not nothing
  • He even acknowledges in his book that a quantum vacuum is not nothing
  • He thinks that the nothing has properties, even though it has no being
  • It has the property of being unstable
  • It has the property of being acted on by quantum fields
  • It has the property of being acted on by gravity

Krauss:

  • But nothing can have the potential to do things inside it
  • For example suppose you have an electron, which is not nothing
  • If it jumps from one level to another, it emits light
  • There was no potential for the light in the electron, but it was there as part of atomic structure

Holder:

  • But in cases like that, there is something physical that has the potential
Krauss:
  • Well, how did God makes the universe then if it had no potential?

Holder:

  • God existed, and the potential for creating the universe in himself

Brierley:

Krauss:
  • It was written by a philosopher, so I dismissed it

Brierley:

Krauss:
  • These book reviewers have not even read my book!

Krauss:

  • Science will be able to figure out how to make something from nothing in the future
  • We are even now speculating about interesting questions, like is there a multiverse?

Brierley:

  • Consider the critical review of your book in the New York Times
  • The author of the review claims that you equivocate on the term “nothing”
  • In order to get things to pop into being, you have to make “nothing” mean “something”
  • Reviewer: none of Krauss’ theories explain how something can come from actual nothingness

Krauss:

  • In physics, something and nothing are not that different
  • The reviewer doesn’t understand the physics
  • He doesn’t understand quantum field theory
  • You could call a quantum vacuum “nothing”, (this is the vacuum fluctuation model, refuted by William Lane Craig in a peer-reviewed publication in an astrophysics journal – get the full text of the article here)
  • Maybe there is an eternally existing multiverse that we can’t observe or test scientifically
  • Maybe it has laws that we don’t know about which allow our universe to pop into being
  • Maybe this popping into being is uncaused
  • (alarmed) Who made God? Who made God?

Holder:

  • God is eternal and necessary

Krauss:

  • (interrupting, angry) What does it mean for something to be necessary?

Holder:

  • Basically, you have to decide whether there is more evidence that the necessary being God or a multiverse

Brierley:

  • So Dr. Krauss are you willing to say that the universe is a brute fact, in some sense, and requires no explanation

Krauss:

  • (angry) Religious people are stupid because they just assume brute facts, not like me and my unobservable, untestable multiverse
  • (angry) Religious people are against the progress of science, they don’t want to figure out how things work

Brierley:

  • But isn’t it possible that naturalists can be opposed to the progress of science?
  • What about the way the Fred Hoyle opposed the Big Bang because he wanted an eternal universe

Krauss:

  • (angry) But naturalists like me let the facts determine our beliefs, like the facts about the eternal unobservable, untestable multiverse
  • (angry, shouting) Philosophers are stupid, they know nothing!

=== Break ===

Brierley:

  • Do you see any evidence of purpose in the universe?

Krauss:

  • Well maybe I would believe if the stars lined up to spell out a message from God

Brierley:

  • Actually no, that wouldn’t be evidence for God on your multiverse view
  • if there an infinite number of universes existing for an infinite amount of time, then anything can happen no matter how unlikely it is
  • therefore, no evidence could convince you that God exists, since the unobservable, untestable, eternal multiverse can make anything it wants

Krauss:

  • That’s a true statement, and very convenient for atheists who don’t want to be accountable to God, don’t you think?
Brierley:
  • Back to the multiverse, how does it solve the fine-tuning?

Krauss:

  • “We have no idea if the universe is fine-tuned for life”, even though the atheist Martin Rees who endorsed Krauss’ book wrote his own book about the fine-tuning of the universe called “Just Six Numbers”
  • Inflationary theory does suggest a way to create multiple universes, (this is the chaotic inflationary model, refuted by William Lane Craig in a peer-reviewed publication in an astrophysics journal – get the full text of the article here)

Brierley:

  • But this theory is still very much a hypothesis, isn’t it? We can’t observe or test this hypothesis can we?

Krauss:

  • “No, and that is really important to state”
  • “I’m an empiricist, so if you can’t falsify it and if you can’t test it then it’s not science”
  • In my book, I speculate about a way that we could test the multiverse theory

Holder:

  • Yes, in principle, the multiverse would be scientific if you could test it through other theories like inflationary theory
  • There are a lot of speculations about multiverse theory, but no evidence from predictions that were validated in the lab

Krauss:

  • “I agree completely with everything you just said”

Brierley:

  • Roger Penrose agrees with Holder that the multiverse theory is too speculative
  • (To Holder) Isn’t the multiverse theory better than positing a completely different kind of being, which is God?

Holder:

  • The multiverse theory is extremely speculative
  • Even if the multiverse were true, you would still need to explain the multiverse

Krauss:

  • People don’t oppose my book because it’s full of self-contradictory speculations
  • People oppose my book because they are stupid and ignorant

Holder:

  • There are things that exist that science cannot measure, like objective morality
  • It’s possible to give explanations for moral behavior by appealing to evolution
  • But that does not ground self-sacrificial morality, such as what occurs in the Christian life

Brierley:

  • Dawkins says there is no purpose or morality in in the universe, do you agree?

Krauss:

  • “There is certainly no evidence of any of that”

Brierley:

  • In the book, you talk about how we live in a special time in the universe’s history to be able to do science, (i.e. – The Privileged Planet hypothesis)
  • You also write about how all the discoveries were are making will not be communicated to anyone in other places in the universe
  • So what is the meaning of doing science on your view? And why are you sad at the knowledge that will not be available to people in the future?
  • Are you longing for some kind of purpose?

Krauss:

  • No, I just get enjoyment from studying the universe with science to gain understanding

Holder:

  • What do you make of Einstein’s statement about the unexpected comprehensibility of the universe
  • Theists would say that this is because God wanted us to study and understand and gain knowledge

Krauss:

  • “It is remarkable that the universe is comprehensible”

Brierley:

  • Why is the universe comprehensible?

Krauss:

  • Well, maybe the universe just has to be that way

Brierley:

  • What do you make of the heat death of the universe, when all life in the universe will die out?

Krauss:

  • That’s the way the universe is
=== BREAK ===

Krauss:

  • I wouldn’t want to live in a universe where there was a God
  • God is a cosmic Saddam Hussein
  • “Religious people turn their minds off” and believe in God for consolation

Holder:

  • First, Jesus is the revelation of God and he is no Saddam Hussein
  • Second, the Christian life is anything but easy, we are facing some persecution already in the UK
  • Third, there is also the problem of being accountable to God when we die
  • It’s very much like science – Christianity is the way it is, not the way we want it to be

Krauss:

  • “If you don’t believe in him, you don’t get any of the benefits, so you have to believe”
  • “And then if you’ve done something wrong, you’re going to be judged for it”
  • “So I don’t want to be judged by God, I want to be… that’s the bottom line”

Holder:

  • Well, Jesus has died to pay the price for those things we’ve done wrong
  • Although we will have to face the charges for what we’ve done, believers will ultimately be forgiven

UPDATE: Peter Sean Bradley note that Krauss is now walking back his rhetoric in response to criticisms from people like atheist John Horgan.
