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

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.

Brian Auten interviews pro-life debater Scott Klusendorf

Unborn baby scheming about making abortion unthinkable
Unborn baby scheming about making abortion unthinkable

Scott Klusendorf is a tough, practical pro-life debater. When you listen to him talk about moral issues, it’s like listening to Tim Tebow talk about running the two-minute offense. Even if you are not into bio-ethics, you will have a good time listening to him work through the topics. Anyone who likes to understand issues strategically and operationally will enjoy this interview. It’s extremely practical because Scott is the top pro-life debater in the world. He has had to defend all of his views on the field.

Details:

Today’s interview is witth Scott Klusendorf, president of Life Training Institute. LTI is the first place to look for excellent resources to get better equipped to defend the pro-life position. Scott talks about defining abortion and its terms, the issue of the debate, the legal history of abortion, defending the pro-life view using science and philosophy, the four pillars of the pro-life argument, answering a litany of objections to the pro-life position, the right and wrong use of emotional appeals, taking on the right tone in the debate, how to get better equipped, and more.

Click here to get the 45 minute interview. The article he mentions “How to Defend Your Pro-Life Views in 5 Minutes or Less” is worth the read, and it’s a good summary of some of the points he makes in the lecture.

If you like this interview, please be sure and buy the best basic book on pro-life apologetics – Scott Klusendorf’s “The Case for Life“. I do have to mention that Scott is an evangelical Christian. Evangelicals are very much into understanding and debating pro-life and pro-marriage positions – we want to understand and we want to explain why we believe what we believe.

You can learn more by reading basic pro-life apologetics… from Francis Beckwith. You might recognize Frank Beckwith as the author of “Defending Life: A Moral and Legal Case Against Abortion Choice“. He wrote that book for Cambridge University Press, a top academic press. But before Cambridge University Press, Beckwith wrote easy-to-understand essays for the Christian Research Journal.

Here are four essays that answer common arguments in favor of legalized abortion.

Part I. The Appeal to Pity

Excerpt:

Anyone who keeps up with the many pro-choice demonstrations in the United States cannot help but see on pro-choice placards and buttons a drawing of the infamous coat hanger. This symbol of the pro-choice movement represents the many women who were harmed or killed because they either performed illegal abortions on themselves (i.e., the surgery was performed with a “coat hanger”) or went to unscrupulous physicians (or “back-alley butchers”). Hence, as the argument goes, if abortion is made illegal, then women will once again be harmed. Needless to say, this argument serves a powerful rhetorical purpose. Although the thought of finding a deceased young woman with a bloody coat hanger dangling between her legs is — to say the least — unpleasant, powerful and emotionally charged rhetoric does not a good argument make.

The chief reason this argument fails is because it commits the fallacy of begging the question. In fact, as we shall see, this fallacy seems to lurk behind a good percentage of the popular arguments for the pro-choice position. One begs the question when one assumes what one is trying to prove. Another way of putting it is to say that the arguer is reasoning in a circle. For example, if one concludes that the Boston Celtics are the best team because no team is as good, one is not giving any reasons for this belief other than the conclusion one is trying to prove, since to claim that a team is the best team is exactly the same as saying that no team is as good.

The question-begging nature of the coat-hanger argument is not difficult to discern: only by assuming that the unborn are not fully human does the argument work. If the unborn are not fully human, then the pro-choice advocate has a legitimate concern, just as one would have in overturning a law forbidding appendicitis operations if countless people were needlessly dying of both appendicitis and illegal operations. But if the unborn are fully human, this pro-choice argument is tantamount to saying that because people die or are harmed while killing other people, the state should make it safe for them to do so.

Part II. Arguments from Pity, Tolerance, and Ad Hominem

Excerpt:

A woman who becomes pregnant due to an act of either rape or incest is the victim of a horribly violent and morally reprehensible crime. Although pregnancy as a result of either rape or incest is extremely rare, [1] there is no getting around the fact that pregnancy does occur in some instances.

[…]Despite its forceful appeal to our sympathies, there are several problems with this argument. First, it is not relevant to the case for abortion on demand, the position defended by the popular pro-choice movement. This position states that a woman has a right to have an abortion for any reason she prefers during the entire nine months of pregnancy, whether it be for gender-selection, convenience, or rape. [3] To argue for abortion on demand from the hard cases of rape and incest is like trying to argue for the elimination of traffic laws from the fact that one might have to violate some of them in rare circumstances, such as when one’s spouse or child needs to be rushed to the hospital. Proving an exception does not establish a general rule.

[…]Fourth, this argument begs the question by assuming that the unborn is not fully human. For if the unborn is fully human, then we must weigh the relieving of the woman’s mental suffering against the right-to-life of an innocent human being. And homicide of another is never justified to relieve one of emotional distress. Although such a judgment is indeed anguishing, we must not forget that the same innocent unborn entity that the career-oriented woman will abort in order to avoid interference with a job promotion is biologically and morally indistinguishable from the unborn entity that results from an act of rape or incest. And since abortion for career advancement cannot be justified if the unborn entity is fully human, abortion cannot be justified in the cases of rape and incest. In both cases abortion results in the death of an innocent human life. As Dr. Bernard Nathanson has written, “The unwanted pregnancy flows biologically from the sexual act, but not morally from it.” [5]Hence, this argument, like the ones we have already covered in this series, is successful only if the unborn are not fully human.

Part III. Is The Unborn Human Less Than Human?

(No excerpt)

Part IV. When Does a Human Become a Person?

Excerpt:

Some ethicists argue that the unborn becomes fully human sometime after brain development has begun, when it becomes sentient: capable of experiencing sensations such as pain. The reason for choosing sentience as the criterion is that a being that cannot experience anything (i.e., a presentient unborn entity) cannot be harmed. Of course, if this position is correct, then the unborn becomes fully human probably during the second trimester and at least by the third trimester. Therefore, one does not violate anyone’s rights when one aborts a nonsentient unborn entity. [13]

There are several problems with this argument. First, it confuses harm with hurt and the experience of harm with the reality of harm. [14] One can be harmed without experiencing the hurt that sometimes follows from that harm, and which we often mistake for the harm itself. For example, a temporarily comatose person who is suffocated to death “experiences no harm,” but he is nevertheless harmed. Hence, one does not have to experience harm, which is sometimes manifested in hurt, in order to be truly harmed.

Second, if sentience is the criterion of full humanness, then the reversibly comatose, the momentarily unconscious, and the sleeping would all have to be declared nonpersons. Like the presentient unborn, these individuals are all at the moment nonsentient though they have the natural inherent capacity to be sentient. Yet to countenance their executions would be morally reprehensible. Therefore, one cannot countenance the execution of some unborn entities simply because they are not currently sentient.

Someone may reply that while these objections make important points, there is a problem of false analogy in the second objection: the reversibly comatose, the momentarily unconscious, and the sleeping once functioned as sentient beings, though they are now in a temporary state of nonsentience. The presentient unborn, on the other hand, were never sentient. Hence, one is fully human if one was sentient “in the past” and will probably become sentient again in the future, but this cannot be said of the presentient unborn.

There are at least three problems with this response. First, to claim that a person can be sentient, become nonsentient, and then return to sentience is to assume there is some underlying personal unity to this individual that enables us to say that the person who has returned to sentience is the same person who was sentient prior to becoming nonsentient. But this would mean that sentience is not a necessary condition for personhood. (Neither is it a sufficient condition, for that matter, since nonhuman animals are sentient.) Consequently, it does not make sense to say that a person comes into existence when sentience arises, but it does make sense to say that a fully human entity is a person who has the natural inherent capacity to give rise to sentience. A presentient unborn human entity does have this capacity. Therefore, an ordinary unborn human entity is a person, and hence, fully human.

Second, Ray points out that this attempt to exclude many of the unborn from the class of the fully human is “ad hoc and counterintuitive.” He asks us to “consider the treatment of comatose patients. We would not discriminate against one merely for rarely or never having been sentient in the past while another otherwise comparable patient had been sentient….In such cases, potential counts for everything.” [15]

Third, why should sentience “in the past” be the decisive factor in deciding whether an entity is fully human when the presentient human being “is one with a natural, inherent capacity for performing personal acts?” [16] Since we have already seen that one does not have to experience harm in order to be harmed, it seems more consistent with our moral sensibilities to assert that what makes it wrong to kill the reversibly comatose, the sleeping, the momentarily unconscious, and the presentient unborn is that they all possess the natural inherent capacity to perform personal acts. And what makes it morally right to kill plants and to pull the plug on the respirator-dependent brain dead, who were sentient “in the past,” is that their deaths cannot deprive them of their natural inherent capacity to function as persons, since they do not possess such a capacity.

These four essays are a very good introduction to common responses to pro-abortion arguments. I recommend that people get familiar with this, as once you look into it, you will see that the abortion issue can be debated with as much confidence as William Lane Craig defends Christian theism. You will have the same access to scientific evidence and rational arguments on this topic, and so you will have the upper hand. And that’s fun.

Why do some people disagree with the gay lifestyle?

Here’s an article from the liberal New York Times that explains one practical reason why social conservatives disagree with the gay lifestyle and prefer not to celebrate it. (H/T Neil)

Here’s the set up:

BOB BERGERON was so relentlessly cheery that people sometimes found it off-putting. If you ran into him at the David Barton Gym on West 23rd Street, where he worked out nearly ever morning at 7, and you complained about the rain, he would smile and say you’d be better off focusing on a problem you could fix.

That’s how Mr. Bergeron was as a therapist as well, always upbeat, somewhat less focused on getting to the root of his clients’ feelings than altering behavior patterns that were detrimental to them: therapy from the outside-in.

Over the last decade, he built a thriving private practice, treating well-to-do gay men for everything from anxiety to coping with H.I.V. Mr. Bergeron had also begun work as a motivational speaker, giving talks at gay and lesbian centers in Los Angeles and Chicago. In February, Magnus Books, a publisher specializing in gay literature, was scheduled to print a self-help guide he had written, “The Right Side of Forty: The Complete Guide to Happiness for Gay Men at Midlife and Beyond.”

It was a topic he knew something about. Having come out as gay in the mid-1980s, Mr. Bergeron, 49, had witnessed the worst years of the AIDS epidemic and emerged on the other side. He had also seen how few public examples there were of gay men growing older gracefully.

He resolved to rewrite the script, and provide a toolbox for better living.

“I’ve got a concise picture of what being over 40 is about and it’s a great perspective filled with happiness, feeling sexy, possessing comfort relating to other men and taking good care of ourselves,” Mr. Bergeron said on his Web site.  “This picture will get you results that flourish long-term.”

But right around New Year’s Eve, something went horribly wrong. On Jan. 5, Mr. Bergeron was found dead in his apartment, the result of a suicide that has left his family, his friends and his clients shocked and heartbroken as they attempt to figure out how he could have been so helpful to others and so unable to find help himself.

Look:

To his friends, Mr. Bergeron maintained a positive tone. He went on vacation, dated some, visited museums.

Still, he privately expressed misgivings about what the future held. Olivier Van Doorne, a patient of Mr. Bergeron and the creative director of SelectNY, a fashion advertising firm, recalled Mr. Bergeron telling him that every gay man peaks at one point in his life.

“He said a number of times: ‘I peaked when I was 30 or 35. I was super-successful, everyone looked at me, and I felt extremely cool in my sexuality.’ ”

Mr. Siegel, the therapist who supervised Mr. Bergeron in the early days of his career, said: “Bob was a very beautiful younger man, and we talked a lot about how that shapes and creates a life. The thesis of his book is based very much on his own personal experience with that. And the book also emphasized what to do when you’re not attractive or you no longer have the appeal you once had. The idea was to transcend that and expand your sexual possibilities.”

And:

With the book about to be printed, Mr. Bergeron became convinced that he’d written too much about the shame and isolation involved with hooking up online; that people weren’t even really doing that anymore, now that phone apps like Grindr and Scruff had come along.

His book, he felt, had become antiquated before it even came out.

[…]Though some of his friends, Mr. Rappaport among them, wondered whether drugs were involved, leading to a crash Mr. Bergeron did not anticipate, the suicide seemed to have been carried out with methodical precision. On an island in the kitchen, Mr. Bergeron had meticulously laid out his papers. There was a pile of folders with detailed instructions on top about whom to call regarding his finances and his mortgage. Across from that he placed the title page of his book, on which he also wrote his suicide note. In it he told Mr. Sackheim and Mr. Rappaport that he loved them and his family, but that he was “done.”

As his father remembered it, Mr. Bergeron also wrote, “It’s a lie based on bad information.”

An arrow pointed up to the name of the book.

The inference was clear. As Mr. Bergeron saw it at the end of his life, the only right side of 40 was the side that came before it.

What’s the problem?

I think that the problem is that in the gay lifestyle, you have a typically male emphasis on physical appearance, sex and pleasure. There is none of the moderating influence of women, which tends to push men into commitments, responsibility and stability.

According to the research, the gay lifestyle is very different than the traditional heterosexual courting approach:

The 2003-2004 Gay/Lesbian Consumer Online Census surveyed the lifestyles of 7,862 homosexuals. Of those involved in a “current relationship,” only 15 percent describe their current relationship as having lasted twelve years or longer, with five percent lasting more than twenty years.[4]

A study of homosexual men in the Netherlands published in the journal AIDS found that the “duration of steady partnerships” was 1.5 years.[6]

In his study of male homosexuality in Western Sexuality: Practice and Precept in Past and Present Times, Pollak found that “few homosexual relationships last longer than two years, with many men reporting hundreds of lifetime partners.”[7]

And:

The Dutch study of partnered homosexuals, which was published in the journal AIDS, found that men with a steady partner had an average of eight sexual partners per year.[12]

In their study of the sexual profiles of 2,583 older homosexuals published in the Journal of Sex Research, Paul Van de Ven et al. found that “the modal range for number of sexual partners ever [of homosexuals] was 101-500.” In addition, 10.2 percent to 15.7 percent had between 501 and 1,000 partners. A further 10.2 percent to 15.7 percent reported having had more than one thousand lifetime sexual partners.[14]

A survey conducted by the homosexual magazine Genre found that 24 percent of the respondents said they had had more than one hundred sexual partners in their lifetime. The magazine noted that several respondents suggested including a category of those who had more than one thousand sexual partners.[15]

And:

Even in those homosexual relationships in which the partners consider themselves to be in a committed relationship, the meaning of “committed” or “monogamous” typically means something radically different than in heterosexual marriage.

A Canadian study of homosexual men who had been in committed relationships lasting longer than one year found that only 25 percent of those interviewed reported being monogamous.” According to study author Barry Adam, “Gay culture allows men to explore different…forms of relationships besides the monogamy coveted by heterosexuals.”[16]

[…]In their Journal of Sex Research study of the sexual practices of older homosexual men, Paul Van de Ven et al. found that only 2.7 percent of older homosexuals had only one sexual partner in their lifetime.[19]

In the gay lifestyle, men seem to have the most value when they are younger and more good-looking. The whole thing seems to be very much about appearance and sex – having as much sex as possible with as many different men as possible. (See, for example, the popular Grindr application on the iPhone, which allows gays to find other gays for anonymous hook-up sex)

This is really sad, because it means that as the gay men get older and their looks fade, they lose value in the area that counts the most to many of them: sexuality. This is different than in a traditional heterosexual marriage, where the man retains his value longer since he can perform his traditional male roles as a husband and father even after he gets older and loses his looks. In fact, his ability to protect, provide and lead on moral and spiritual issues can actually get better as he gets older – so his self-esteem goes up. Now it’s true that he can get depressed when he retires, but by then he’s probably around 65! And at least he will have a wife there to take care of them, and probably children to support, too. My Dad, for example, does lots of things to help me even though he is retired.

I think this NYT article sheds light on why people with traditional values tend to disagree with homosexuality and also to refrain from celebrating and affirming the gay lifestyle. We treat the gay lifestyle as if it were similar to smoking. It’s permissible, but not to be encouraged. We are not trying to make anyone feel badly just for the sake of being mean to them. If a certain lifestyle is not fulfilling, then it is a good thing to say to people “you should think twice about getting involved in this”. It’s not loving to tell people that harmful things are not really harmful. Telling someone that something unfulfilling or unhealthy is actually good for them doesn’t help them any. It’s not loving to tell a child that touching a hot stove won’t burn them – the loving thing to do is to tell the truth and then let them choose.

Here’s my previous post outlining a secular case against gay marriage.
