William Lane Craig debates Victor Stenger: Does God Exist?

1 Comment

This debate took place on March 1, 2010 at Oregon State University.

In this debate, Victor Stenger does affirm his belief that the universe could be eternal in his second rebuttal (1:02:30), thus denying the standard Big Bang cosmology. He also denies the law of conservation of energy and asserts that something can come from nothing in his concluding speech (1:33:50). He also caused the audience to start laughing when he said that Jesus was not moral and supported slavery. There is almost no snark in this summary. Instead, I quoted Dr. Stenger verbatim in many places. I still think that it is very entertaining even without the snarky paraphrasing.

The debate includes 30 minutes of Q&A with the students.

Here is the MP3 file for the audio.

Here’s the video of the debate:

Dr. Craig’s opening speech:

  • The ontological argument
  • The contingency argument
  • The cosmological argument
  • The moral argument
  • The resurrection of Jesus (3-fact version)
  • Religious experience

Dr. Stenger’s opening speech:

  • There is no scientific evidence for God’s existence in the textbooks
  • There is no scientific evidence for God acting in the universe
  • God doesn’t talk to people and tell them things they couldn’t possibly know
  • The Bible says that the Earth is flat, etc.
  • There is no scientific evidence that God answers prayers
  • God doesn’t exist because people who believe in him are ignorant
  • Human life is not optimally designed and appears to be the result of a blind, ad hoc evolutionary process
  • The beginning of the universe is not ordered (low entropy) but random and chaotic
  • It’s theoretically possible that quantum tunneling explains the origin of the universe
  • The laws of physics are not objectively real, they are “our inventions”
  • Regarding the beginning of the universe, the explanation is that something came from nothing*
  • Nothing* isn’t really nothing, it is “the total chaos that we project existed just before the big bang”
  • If something has no structure, then “it is as much nothing as nothing can be”
  • Consciousness is explainable solely on the basis of material processes
  • There are well-informed, rational non-believers in the world and God would not allow that

Dr. Craig’s first rebuttal:

Stenger’s argument that there is no objective evidence for God’s existence:

  • First, it is not required that God rely only on objective evidence in order to draw people to himself (Alvin Plantinga)
  • Second, God is not required to provide evidence to everyone, only to the people who he knows would respond to him
  • Third, Craig gave lots of objective evidence, from science, history and philosophy
  • Stenger asks for certain evidence (answered prayers, prophecy, etc.), but Craig presented the evidence we have

Stenger’s argument that the balance of energy is zero so “nothing” exists:

  • if you have the same amount of assets and liabilities, it doesn’t mean that nothing exists – your assets and liabilities exist
  • Christopher Isham says that there needs to be a cause to create the positive and negative energy even if they balance
  • the quantum gravity model contradicts observations
  • the vacuum is not the same as nothing, it contains energy and matter
  • the BVG theorem proves that any universe that is expanding must have a beginning

Stenger’s argument that mental operations can be reduced to physical operations:

  • mental properties are not reducible to physical properties
  • epiphenomenalism: is incompatible with self-identity over time
  • epiphenomenalism: is incompatible with thoughts about other things
  • epiphenomenalism: is incompatible with free will
  • substance dualism (mind/body dualism) is a better explanation for our mental experience
  • God is a soul without a body
Dr. Stenger’s first rebuttal:

Craig’s cosmological argument:

  • Craig’s premise is “everything has a cause”, but quantum mechanics has causeless events
  • There are speculative theories about how something could have come into being uncaused out of nothing
  • “I don’t know of a single working cosmologist today who believes there was a singularity prior to the Big Bang”
  • “If there wasn’t a singularity then there’s no basis for arguing that time began at that point”
  • “There’s no reason from cosmology that we know of that the universe can’t be eternal”
  • “When I talk about an eternal universe, I mean a universe that has no beginning or end”
  • The Hartle-Hawking model doesn’t have a beginning
  • “There was no violation of energy conservation by having a universe coming from nothing”
  • “The universe could have come from a previous universe for example or even just from a region of chaos”
  • The paper by Vilenkin is counteracted by other papers (he doesn’t specify which ones)

Craig’s moral argument:

  • Dr. Craig is arguing from ignorance
  • But morality can be decided by humanity just like governments pass laws, and that’s objective
  • Dr. Craig has too little respect for the human intellect
  • I don’t need to tell me that slavery is wrong
  • The Bible supports slavery
  • Atheists can behave as good as theists
  • Morality just evolved naturally as an aid to survival

Craig’s resurrection argument:

  • No Roman historians wrote about the execution of Jesus but none of them did
  • The empty tomb is doubtful because it is only mentioned in the gospels, not by Paul
  • John Dominic Crossan says there was no empty tomb
  • Christianity only survived because the Roman empire thought that they were useful

Dr. Craig’s second rebuttal:

Craig’s cosmological argument:

  • There is no reason to prefer an indeterministic interpretation of quantum mechanics
  • Dr. Stenger himself wrote that deterministic interpretations of quantum mechanics are possible
  • The vacuum in quantum mechanics is not nothing
  • The quantum vacuum he proposes cannot be eternal
  • The cosmological argument does not require a singularity
  • The Hartle-Hawking model is from 1983
  • Hawking says that there is a beginning of space and time after that model
  • The Hartle-Hawking model does still have a beginning of time – the model is not eternal
  • The BVG theorem that requires a beginning for expanding universes is widely accepted among cosmologists

Craig’s moral argument:

  • Stenger redefined objective to mean that most people agree with it – but that’s not what objective means
  • Objective means right and wrong whether anyone accepts it or not
  • Richard Dawkins himself says that on atheism there is “no evil and no good” – why is he wrong?
  • Even Dr. Stenger says that morality is the same as passing laws – it’s arbitrary and varies by time and place
  • But on his view, right and wrong are the same as deciding which side of the road to drive on
  • But somethings really are right and some things are really wrong

Craig’s resurrection argument:

  • Josephus is a Roman historian and he wrote about Jesus, for example
  • There were four biographies of Jesus are the best sources for his life
  • The scholars that Stenger mentioned are on the radical fringe

Dr. Stenger’s second rebuttal:

Knowledge and the burden of proof:

  • Dr. Craig has to bear the burden of proof, not me – because his claim is more “extravagant”
  • “I don’t have to prove that a God was not necessary to create the universe”
  • “I don’t have to prove that a God did not design the universe and life”
  • “I don’t have to prove that the universe did not have a beginning”
  • “I don’t have to prove that God did not provide us with our moral sense”
  • There are a lot of books written about how morality evolved naturally
  • “I don’t have to prove that the events surrounding the supposed resurrection of Jesus did not take place”
  • Bart Ehrman says that the gospels are generally unreliable (Note: Ehrman accepts all 3 of Craig’s minimal facts)
  • Just because people are willing to die for a cause, does not make their leader God, e.g. – the Emperor of Japan

Aesthetic concerns about the universe:

  • I don’t like dark matter and I wouldn’t have made the universe with dark matter
  • I don’t like the doctrine of penal substitution
  • I don’t like the doctrine of original sin
  • I don’t like the heat death of the universe

Dr. Craig’s conclusion:

The case for atheism:

  • Dr. Stenger had two arguments and he has to support his premises
  • Dr. Craig addressed his two arguments and each premise and Dr. Stenger never came back on it

The contingency argument:

  • Dr. Stenger has dropped the refutation of this argument

The cosmological argument:

  • The theoretical vacuum he proposes cannot be eternal

The moral argument:

  • He asserts that things are wrong, but there is no grounding for that to be objective on atheism

The resurrection of Jesus:

  • There are surveys of scholars on the empty tomb and 75% of them agree with it
  • Bart Ehrman agrees with all 3 of the minimal facts that Dr. Craig presented
  • Ehrman’s objection to the resurrection is not historical: he’s an atheist – he thinks miracles are impossible

Religious experience:

  • No response from Dr. Stenger

Dr. Stenger’s conclusion

The cosmological argument:

  • “I argued that we have very good physical reasons to understand how something can come from nothing”
  • “There is a natural tendency in the universe… to go from.. simpler thing to the more complicated thing”
  • The transition from a vapor to a liquid to ice shows how something could come from nothing
  • “It cannot be proven that the universe had a beginning”

The moral argument:

  • Objective morality, which is independent of what people think, could be developed based on what people think
  • “Jesus himself was not a tremendously moral person… he had no particular regard for the poor… he certainly supported slavery… he was for the subjugation of women” (audience laughter)

The resurrection argument:

  • Bart Ehrman says that the majority of the gospels are unreliable

Religious experience:

  • I don’t see any evidence that there is anything more to religious experience than just stuff in their heads

God’s purpose of the world should be to make people feel happy:

  • God could have made people feel happier
  • God could have made people not die
  • God could could have made the universe smaller: it’s too big
  • God could have made it possible for humans to live anywhere “even in space”

Basic economics: what’s wrong with raising minimum wage rates?

7 Comments
Economist Thomas Sowell
Economist Thomas Sowell

From Investors Business Daily, an article by famous economist Thomas Sowell.

Excerpt:

Political crusades for raising the minimum wage are back again. Advocates of minimum-wage laws often give themselves credit for being more “compassionate” towards “the poor.”

But they seldom bother to check what are the actual consequences of such laws.

One of the simplest and most fundamental economic principles is that people tend to buy more when the price is lower and less when the price is higher.

Yet advocates of minimum-wage laws seem to think that the government can raise the price of labor without reducing the amount of labor that will be hired.

[…]Switzerland is one of the few modern nations without a minimum-wage law. In 2003, the Economist magazine reported: “Switzerland’s unemployment neared a five-year high of 3.9% in February.”

In February of this year, Switzerland’s unemployment rate was 3.1%. A recent issue of the Economist showed Switzerland’s unemployment rate as 2.1%.

Most Americans today have never seen unemployment rates that low. However, there was a time when there was no federal minimum-wage law in the United States.

The last time was during the Coolidge administration, when the annual unemployment rate went as low as 1.8%. When Hong Kong was a British colony, it had no minimum-wage law. In 1991 its unemployment rate was under 2%.

[…]Most people in the lower income brackets are not an enduring class. Most working people in the bottom 20% in income at a given time do not stay there over time. More of them end up in the top 20% than remain behind in the bottom 20%.

There is nothing mysterious about the fact that most people start off in entry-level jobs that pay much less than they will earn after they get some work experience.

But when minimum-wage levels are set without regard to their initial productivity, young people are disproportionately unemployed — priced out of jobs.

In European welfare states where minimum wages, and mandated job benefits to be paid for by employers, are more generous than in the United States, unemployment rates for younger workers are often 20% or higher, even when there is no recession.

Unemployed young people lose not only the pay they could have earned but, at least equally important, the work experience that would enable them to earn higher rates of pay later on.

Minorities, like young people, can also be priced out of jobs. In the United States, the last year in which the black unemployment rate was lower than the white unemployment rate — 1930 — was also the last year when there was no federal minimum-wage law.

Inflation in the 1940s raised the pay of even unskilled workers above the minimum wage set in 1938. Economically, it was the same as if there were no minimum-wage law by the late 1940s.

In 1948 the unemployment rate of black 16-year-old and 17-year-old males was 9.4%. This was a fraction of what it would become in even the most prosperous years from 1958 on, as the minimum wage was raised repeatedly to keep up with inflation.

A survey of American economists found that 90% of them regarded minimum-wage laws as increasing the rate of unemployment among low-skilled workers.

Harvard University economist Greg Mankiw puts the agreement level at 79%. This is not controversial. This is one of the most widely-accepted facts in economics. Generally, if you raise the price of domestic labor, without any increase in worker productivity, then it reduces demand for domestic labor and causes companies to reduce hiring and retention, possibly looking elsewhere for labor. Compassionate-sounding policies actually cause negative results like outsourcing and layoffs. The very people who agitate the most for a “living wage” cause higher unemployment – especially among youth and minorities.

The only sure way to help workers is to give them marketable skills and job experience – that’s what really draws higher salaries and better benefits. And that means advocating for smarter policies: fewer regulations on job creators, lowering the employer portion of payroll taxes, merit pay for teachers, vouchers to encourage competition between schools, making work pay more than collecting welfare for doing nothing. And so on. That would actually solve the problem of people not having work.

Global warming: antarctic sea ice extents hits 35-year record high

5 Comments
No significant global warming in 15 years
No significant global warming in 15 years

About two weeks ago, I blogged about record ice extents in the ARCTIC (north pole).

Now, here’s a new story about record ice extents in the ANTARCTIC (south pole) – and from the radically leftist Washington Post, no less.

Excerpt:

Antarctic sea ice has grown to a record large extent for a second straight year, baffling scientists seeking to understand why this ice is expanding rather than shrinking in a warming world.

On Saturday, the ice extent reached 19.51 million square kilometers, according to data posted on the National Snow and Ice Data Center Web site.  That number bested record high levels set earlier this month and in 2012 (of 19.48 million square kilometers). Records date back to October 1978.

[…]In a new study in the Journal of Climate, Zhang finds both strengthening and converging winds around the South Pole can explain 80 percent of the increase in ice volume which has been observed.

“The polar vortex that swirls around the South Pole is not just stronger than it was when satellite records began in the 1970s, it has more convergence, meaning it shoves the sea ice together to cause ridging,” the study’s press release explains. “Stronger winds also drive ice faster, which leads to still more deformation and ridging. This creates thicker, longer-lasting ice, while exposing surrounding water and thin ice to the blistering cold winds that cause more ice growth.”

But no one seems to have a conclusive answer as to why winds are behaving this way.

“I haven’t seen a clear explanation yet of why the winds have gotten stronger,” Zhang told Michael Lemonick of Climate Central.

Some point to stratospheric ozone depletion, but a new study published in the Journal of Climate notes that computer models simulate declining – not increasing – Antarctic sea ice in recent decades due to this phenomenon (aka the ozone “hole”).

“This modeled Antarctic sea ice decrease in the last three decades is at odds with observations, which show a small yet statistically significant increase in sea ice extent,”says the study, led by Colorado State University atmospheric scientist Elizabeth Barnes.

It’s a mystery. How could global warming be false?

Two weeks ago it was Arctic ice extents

Let’s review my previous post about how ARCTIC ice extents had increased 60% from last year, despite predictions by the socialist BBC.

From the UK Telegraph.

Excerpt:

A cold Arctic summer has led to a record increase in the ice cap, leading experts to predict a period of global cooling.

There has been a 60 per cent increase in the amount of ocean covered with ice compared to this time last year, they equivalent of almost a million square miles.

In a rebound from 2012′s record low an unbroken ice sheet more than half the size of Europe already stretches from the Canadian islands to Russia’s northern shores, days before the annual re-freeze is even set to begin.

The Northwest Passage from the Atlantic to the Pacific has remained blocked by pack-ice all year, forcing some ships to change their routes.

A leaked report to the UN Intergovernmental Panel on Climate Change (IPCC) seen by the Mail on Sunday, has led some scientists to claim that the world is heading for a period of cooling that will not end until the middle of this century.

If correct, it would contradict computer forecasts of imminent catastrophic warming. The news comes several years after the BBC predicted that the arctic would be ice-free by 2013.

Despite the original forecasts, major climate research centres now accept that there has been a “pause” in global warming since 1997.

The original predictions led to billions being invested in green measures to combat the effects of climate change.

It’s so bad that environmentalists who thought there wouldn’t be any ice are trapped!

Not only have we had 15 years with no significant global warming, but now we have record ice extents in both the north pole and the south pole. Global warming alarmism is nothing but mythology dressed in a cheap tuxedo. When is the anti-science hysteria of the left going to end? What evidence will it take to convince them not to believe in fairies and leprechauns? I know they get a lot of brainwashing in public schools and universities, but eventually, they get out and they can look through telescopes and microscopes and see for themselves what is real. When experimental science has spoken about observations, then secularist doomsday fiction must give way. Mustn’t it?
