Debating the Kalam argument in a YouTube thread

A new reader to the blog read my article on the Kalam cosmological argument, and he decided to try it out on youtube here. He presented the argument PERFECTLY, and then he got some responses. He asked me to comment, so I will below. But I want you guys to comment, too! (UPDATE: Comment in this post – I don’t recommend commenting in YouTube discussions)

Anyway, here’s the page. (I didn’t watch the video)

And here’s his initial presentation of the argument:

1 Whatever begins to exist requires a cause
2 The universe began to exist
3 Therefore, the universe requires a cause

The cause for the universe (time, space, matter, etc) must be something entirely different (outside the realm of time, space, and matter) since a thing cannot be the cause of itself.

Now I’ll reply to his opponents, but you can reply too in the comments, because he’s reading this post, and we should all try to offer him our thoughts. At the end, I recommend some additional resources, all free online, to help everyone understand the details of this fine argument.

Responses to the Kalam argument

Here’s the first reply:

Just because we don’t know the cause yet doesn’t mean it’s not something scientific. I’m not saying it is, I’m just saying it’s possible.

By “scientific”, I am thinking that this challenger is hoping for a material cause, but the problem is that the origin of the universe is the origin of all space and matter – so no “scientific” cause is possible. So it is not possible that the origin of the universe was caused by something “scientific”, because it’s an absolute origin of all matter, and the physical laws that govern matter, as well. Tell him that there is only one kind of non-material entity capable of causing effects and that is a mind.

Here’s another reply:

What if the universe always existed? We don’t know that it has started to exist, we just know that it exists and that it has existed for very long. So it is possible that it has always existed. So that doesn’t prove anything.

I would ask this person why they hate science so much to deny the good data about the measurements of red-shift in light from distant galaxies, the helium-hydrogen abundance measurements, the cosmic microwave background radiation, the second law of thermodynamics, the star formation cycle, etc. As them what is wrong with science, and why must they push their religion (naturalism) on science?

Here’s another reply:

The same principle can apply to god as well, so this argument doesn’t prove or disprove either it is just pointless.

My response is that the cause of the universe causes the beginning of time as well, and so therefore the cause exists necessarily, outside of time. Things that exist outside of time are eternal, they don’t not exist at time t1 and then begin to exist at time t2. The cause of time’s beginning cannot come into being itself, because there is no t1 and t2 before time is created.

Here’s another reply:

uhm .. no, there is no definition of god like that and even if it is it’s invalid, why ? well mostly because apart from a book “The Bible” there is no real proof he existed, no one has seen him and I’ll wager that no one ever will, henceforth you cannot define something that you really know nothing about, something that might not even exist, it’s like saying that bigfoot is a mammal. you can’t prove that either since you haven’t seen it and don’t even know if it exists

Notice that onlinesid produced an argument for the existence of God, and now this guy is bringing in the Bible (red herring), no proof (red herring), why can’t I see God (red herring), no one knows anything about God (red herring and self-refuting), and bigfoot (red herring). This person is clearly brain-damaged and not one of the things he write is worth a response. Note: I am being mean, but you can’t be mean when you reply to him, you have to tell them to stay focused on your argument and deny premise 1 or premise 2.

And here’s another:

You assume that the universe began to exist.

We currently don’t know if it did or not; the present hypothesis is expansion from a single point that is infinitely small.

You also assume that the cause of the universe doesn’t have a cause. You need to account for the cause of the cause, and the cause of that cause, ad infinitum.

And on “God being outside of” reality, then he shouldn’t be able to affect reality in any observable way. God is untestable.

Again, tell him he is a science-hating flat-earther and ask which of the empirical evidences for the Big Bang he denies. We need to get off of his speculations and evasions and ask him to deny a premise or to deny some scientific data. As soon as he does, ask him for peer-reviewed data that refutes the scientific observations. The cause of the universe doesn’t have a cause because it is outside of time and doesn’t begin to exist. The premise is that only things that begin to exist require a cause. Regarding God not being able to cause effects, you should say that God is a mind and causes effects in time subsequent to creation the same way that humans cause effects using their wills on their bodies.

Here’s another:

It’s called the “Big Bang” hypothesis. Even simple Wikipedia will besufficient for an understanding of it. Or videos on Youtube, if you are that lazy and/or ignorant.

The “evidence” for it is background electromagnetic radiation and the appearance that the universe is expanding. Among other things

The “mind” we perceive is the function of electrochemical impulses between our brain cells. We classify it as a “mind”. And as a physical system of reality, it is affected by physical reality..

Again ask him what is his scientific evidence that the universe is eternal, and ask him what is wrong with your scientific evidence showing that it isn’t eternal. You must make him make a claim and supply evidence for his claim. You need to buy a book called “God and the Astronomers” by agnostic Robert Jastrow and read it. It explains all the discoveries that led to the Big Bang, but get the second edition. Also, if he thinks that mind is biologically determined, then you need to explain that biological determinism makes rationality impossible, since all of our outputs are determined by inputs and DNA programming that has the goal of reproducing, not finding truth.

More challenges:

…The beginning of the universe need not be “God”. Could have been made by a pencil. Or could have always been, like a trigonomic function, repeating and diverging into two dimensions.

I think our boy is beginning to wear him down. He now thinks a pencil caused the entire physical universe to appear out of nothing. But the problem is that a pencil is made of matter and cannot have caused the beginning of all matter. But do go on and make him identify what he thinks the cause is. It can’t be in time, it can’t be matter.

More:

And the theist-point-of-view actually can in no way prove God because there are many OTHER ways it could have happened. A pencil could have been the original cause of the big-bang, or it could repeat like a trig function, eternally epanding, collapsing, expanding in another
dimension, etc.

He’s raising the oscillating model, which is falsified theoretically and observationally. In 1998, the discovery of the year was that the universe would expand forever. The oscillating model also faces theoretical problems with the “bounce” mechanism. Sid, if you still can, try your best in physics class, and take astronomy and physics in university, along with philosophy and logic. It will help you to have more fun in these debates and you’ll know more details.

More:

I did not say that the physical realm is all there is. (Thought there could be two realms, or more.) BUT asuming that an entity exists outside the physical realm and created this universe from that dimension IS illogical.

Ask him for a logical argument that proves that God cannot create matter out of nothing. These assertions need to be backed up with deductive arguments, with premises supported by scientific observations. You can’t just throw around that word “illogical”. It sounds like he is just saying “I don’t like it”. Make sure that you ask him for peer-reviewed papers for anything he says about science, and formal arguments for anything he says is “illogical”.

This time he argues quatum mechanics:

Small particles of matter, at least as I understand it, CAN be “created” from energy. The only real “trouble” is the creation of energy, which “god made it” faces the problem of “what made god?”…

If he wants to argue quantum mechanics, you need to remind him that virtual particles can only appear in a quantum vaccuum, which exists in space. It is not nothing. Also, virtual particles are not as massive as a universe, and those virtual particles only stay in existence for a fraction of a second. So this is not a good analogy for the origin of the entire physical universe.

Further study

You did well, you just need to be meaner in demanding that he bear his share of the burdern of proof. Ask him why you should accept his speculations and assertions, where are his arguments, where is his scientific evidence.

I think that this book would be a good one along with God and the Astronomers, second edition. But read this paper, too, and every William Lane Craig debate you can get your hands on, especially the one with physicist Victor Stenger (video, audio), the follow-up lecture at UC Boulder where Stenger is in the audience, and the second Craig-Dacey debate. When you’re done with that, listen to this lecture and this lecture (I know it’s similar to the first one, but tough!) and this lecture and this lecture. And study more physics if you’re still in school!

God meant for us to enjoy ourselves arguing in his universe. Jesus cured the paralytic to provide evidence for his claims. Similarly, we can use the evidence of nature miracles that science is just now discovering to get the same effect as though we could perform miracles. But we need to understand philosophy and physics down to the details.

How to defend the fine-tuning argument just like William Lane Craig

UPDATE: Welcome visitors from Colliding Universes! Thanks for the link Denyse!

This post is the second in a two part series. In case you missed it, here is Craig’s first argument on the kalam argument.

First of all, if you’re not clear on the fine-tuning argument, click here and read Walter Bradley’s exposition of it. Dr. Walter L. Bradley (C.V. here) is the Distinguished Professor of Engineering at Baylor University. He was also a professor and department head at Texas A&M before going to Baylor. He had his Ph.D at age 24 from the University of Texas and was a tenured professor at 27.

The first argument presented by Bradley in that post is the same argument that Craig used against Hitchens in their debate. (It’s Craig’s second argument in the set of five). Bradley’s version of the argument has been presented live, in-person by Bradley at dozens of universities here and abroad, in front of students and faculty. The lecture I linked to in that post is an MP3.

The fine-tuning argument

The argument goes like this:

  1. The fine-tuning of the universe to support life is either due to law, chance or design
  2. It is not due to law or chance
  3. Therefore, the fine-tuning is due to design

What does it meaning to be fine-tuned for life?

Here are the facts on the fine-tuning:

  • Life has certain minimal requirements; long-term stable source of energy, a large number of different chemical elements, an element that can serve as a hub for joining together other elements into compounds, etc.
  • In order to meet these minimal requirements, the physical constants, (such as the gravitational constant), and the ratios between physical constants, need to be withing a narrow range of values in order to support the minimal requirements for life of any kind.
  • Slight changes to any of the physical constants, or to the rations between the constants, will result in a universe inhospitable to life.
  • The range of possible ranges over 70 orders of magnitude.
  • The constants are selected by whoever creates the universe. They are not determined by physical laws. And the extreme probabilities involved required put the fine-tuning beyond the reach of chance.
  • Although each individual selection of constants and ratios is as unlikely as any other selection, the vast majority of these possibilities do not support the minimal requirements of life of any kind. (In the same way as any hand of 5 cards that is dealt is as likely as any other, but you are overwhelmingly likely NOT to get a royal flush. In our case, a royal flush is a life-permitting universe).

Examples of finely-tuned constants

Here are a couple of examples of the fine-tuning. Craig only gave one example in the debate and didn’t explain how changes to the constant would affect the minimal requirements for life. But Bradley does explain it, and he is a professional research scientist, so he is speaking about things he worked in his polymer research lab. (He was the director)

a) The strong force: (the force that binds nucleons (= protons and neutrons) together in nucleus, by means of meson exchange)

  • if the strong force constant were 2% stronger, there would be no stable hydrogen, no long-lived stars, no hydrogen containing compounds. This is because the single proton in hydrogen would want to stick to something else so badly that there would be no hydrogen left!
  • if the strong force constant were 5% weaker, there would be no stable stars, few (if any) elements besides hydrogen. This is because you would be able to build up the nuclei of the heavier elements, which contain more than 1 proton.
  • So, whether you adjust the strong force up or down, you lose stars than can serve as long-term sources of stable energy, or you lose chemical diversity, which is necessary to make beings that can perform the minimal requirements of living beings. (see below)

b) The conversion of beryllium to carbon, and carbon to oxygen

  • Life requires carbon in order to serve as the hub for complex molecules, but it also requires oxygen in order to create water.
  • Carbon is like the hub wheel in a tinker toy set: you can bind other elements together to more complicated molecules (e.g. – “carbon-based life), but the bonds are not so tight that they can’t be broken down again later to make something else.
  • The carbon resonance level is determined by two constants: the strong force and electromagnetic force.
  • If you mess with these forces even slightly, you either lose the carbon or the oxygen.

Either way, you’ve got no life of any conceivable kind.

Is the fine-tuning real?

Yes, it’s real and it is conceded by the top-rank of atheist physicists. Let me give you a citation from the best one of all, Martin Rees. Martin Rees is an atheist and a qualified astronomer. He wrote a book called “Just Six Numbers: The Deep Forces That Shape The Universe”, (Basic Books: 2001). In it, he discusses 6 numbers that need to be fine-tuned in order to have a life-permitting universe.

Rees writes here:

These six numbers constitute a ‘recipe’ for a universe. Moreover, the outcome is sensitive to their values: if any one of them were to be ‘untuned’, there would be no stars and no life. Is this tuning just a brute fact, a coincidence? Or is it the providence of a benign Creator?

There are some atheists who deny the fine-tuning, but these atheists are in firm opposition to the progress of science. The more science has progressed, the more constants, ratios and quantities we have discovered that need to be fine-tuned. Science is going in a theistic direction. Next, let’s see how atheists try to account for the fine-tuning, on atheism.

Atheistic responses to the fine-tuning argument

There are two common responses among atheists to this argument.

The first is to speculate that there are actually an infinite number of other universes that are not fine-tuned, (i.e. – the gambler’s fallacy). All these other universes don’t support life. We just happen to be in the one universe is fine-tuned for life. The problem is that there is no way of directly observing these other universes and no independent evidence that they exist.

Here is an excerpt from an article in Discover magazine, (which is hostile to theism and Christianity).

Short of invoking a benevolent creator, many physicists see only one possible explanation: Our universe may be but one of perhaps infinitely many universes in an inconceivably vast multiverse. Most of those universes are barren, but some, like ours, have conditions suitable for life.

The idea is controversial. Critics say it doesn’t even qualify as a scientific theory because the existence of other universes cannot be proved or disproved. Advocates argue that, like it or not, the multiverse may well be the only viable non­religious explanation for what is often called the “fine-tuning problem”—the baffling observation that the laws of the universe seem custom-tailored to favor the emergence of life.

The second response by atheists is that the human observers that exist today, 14 billion years after the universe was created out of nothing, actually caused the fine-tuning. This solution would mean that although humans did not exist at the time the of the big bang, they are going to be able to reach back in time at some point in the future and manually fine-tune the universe.

Here is an excerpt from and article in the New Scientist, (which is hostile to theism and Christianity).

…maybe we should approach cosmic fine-tuning not as a problem but as a clue. Perhaps it is evidence that we somehow endow the universe with certain features by the mere act of observation… observers are creating the universe and its entire history right now. If we in some sense create the universe, it is not surprising that the universe is well suited to us.

So, there are two choices for atheists. Either an infinite number of unobservable universes that are not fine-tuned, or humans go back in time at some future point and fine-tune the beginning of the universe, billions of years in the past.

Why the fine-tuning argument matters

We need to make a decision today about how we are going to live. The evidence available today supports the fine-tuning of the universe by a supernatural mind with immense power. The progress of science has strengthened this theory against determined opposition from rival naturalistic theories.

Those are the facts, and we must all choose what to do with them.

Further study

Here is a paper by Walter L. Bradley that contains many more examples of the fine-tuning, and explanations for what happens when you change the constants, quantities and rations even slightly.

How to talk to your co-workers about your faith

UPDATE: Welcome visitors from Apologetics 315! Thanks for the link Brian!

UPDATE: Welcome visitors from Free Canuckistan! Thanks for the linky, Binky!

UPDATE: Welcome visitors from The Happy Catholic! Thanks for the link, Julie!

Today, I’ll talk a little bit about how to go about raising your colors in the workplace. Before we start, here are some catch-up posts on why apologetics matters:

How to be yourself at work, without making other people angry

First of all, concentrate on working hard for the first 3 months after you start a job. Your ability to to raise your colors in the workplace is conditional on your ability to do your job well. For example, I decided to cut my career short a while back in order to go back to school and achieve some more goals, before returning to work:

  • get a Masters degree in computer science (3.9 GPA)
  • get computer science articles published in peer-reviewed journals
  • present research at professional conferences
  • apply for and be awarded patents

Secondly, never fight about work-related conflicts. Your job is not the means by which you will make your mark on the world. You make your mark solely by being an ambassador for Christ. Never sour a work relationship by arguing. State your reasons, and document your dissent. Christianity isn’t about you. Or climbing a corporate ladder.

Let me be clear: With respect to your Christian commitment, your pride, popularity and reputation are expendable.

Thirdly, take every opportunity to make yourself the servant of your co-workers, especially those who may not be as senior or technical as you. In every job I have had so far, I’ve tried to help clean things up, wash dirty coffee mugs and dishes, and keep a supply cough drops, and other healthy snacks, etc. Also, don’t get promoted to manager.

Fourth, after a few months, start to build your bookshelf at work. To start with, only stock debate books from academic presses, especially Oxford University Press and Cambridge University Press. These kinds of books connect evidence to the claims of Christianity. It is much easier to discuss public, testable evidence with your co-workers than whether they are going to Hell or not .

Here are some examples of debate books I stock:

Leave these books out on your desk as you read them, with a bookmark to show you are reading them. If asked to explain them, take no position but explain both sides. Speak quietly and don’t interrupt. Stop talking after 2 minutes. Offer to continue the conversations off-site. Learn what your co-workers believe as they talk to you about your perfectly acceptable debate books.

As you read, note arguments and evidence used for and against your beliefs. When you eventually do get to the point where you are explaining your beliefs to people, you’ll need to link them up with evidence and defeat objections. Keep the discussion on public evidence, show you are operating at a research level, and you should be able to avoid blow-ups.

Fifth, expand your book collection with books from any academic press. Your goal is to show that these topics require study and can be debated rationally using evidence. Even if you only read popular level books to start, it is important to project to your co-workers how you approach faith just like any other discipline – by studying it.

If you get no flak from anyone, you can add more books on other issues, like the history, foreign policy, health care, education, philosophy of religion, astrobiology, global warming, economics and family/parenting. These books allow you to link your beliefs to other areas, so that turning the conversation to Christianity becomes easier.

The academic books are useful to convey that you have a serious approach to faith. But you probably will face much more ordinary objections. So, you should be reading mostly popular books to address them. That’s where books by people like Lee Strobel and Paul Copan are useful. After those two, you can move on to edited collections like “Passionate Conviction” or “Signs of Intelligence”.

An important rule is never to discuss the person’s personal life or morality. And never discuss Christian-ese hymns, prayer, church, feelings, emotions, intuitions, religious experiences, or your own life. Untestable faith claims scare people. Stick to the public, testable evidence. Debate whether DNA is designed, not whether they should stop shacking up.

Only talk to people who don’t offend easily and who don’t subscribe to politically correct ideologies. I avoid talking about spiritual things with people from groups that vote overwhelmingly democrat, such as single or divorced women. Eventually, the victim-mentality people will learn to behave in order to talk with you. Avoid breaking cover to anyone in your chain of command.

Sixth, you need to get comfortable with opposing views. In order to do that, you need to get used to being quiet and tolerant, and listening for extended periods of time, while ideas you oppose are forcefully presented. The goal is to be able to recognize your opponent’s arguments and argue for them better than they can themselves.

Start with these university debate transcripts: (print them out, leave them on your desk)

Your goal is to speak about Christianity the same way Craig does. Move on to audio and video debates in this list, only after you master reading debates. Debate your friends and family first for practice. I will write a separate post on what to buy to augment your resource collection with actual debates and lectures that you can lend out.

Another important point: your goal is not to win during the discussion. Try not to beat up your opponent. Instead, explore the issue from both sides using public, testable evidence. Let the person decide for themselves what they think, after the discussion is over. Here’s a great book on tactics that will help you.

An example of authentic Christianity in the public square

One last thing. You may be encouraged by listening to some lectures by Dr. Walter L. Bradley (C.V. here). Bradley is the best active proponent of public, authentic Christianity. He is the Distinguished Professor of Engineering at Baylor. He has a huge pile of grants and research papers, and directed a research lab when he was at Texas A&M.

Here are a couple of different versions of the same lecture on integrating faith and vocation:

And here are a few other Bradley lectures I really like:
