Word of the Day: Theory and Law

A novel of Christian apologeticsLet’s start with a few definitions within mathematics and logic.  An axiom or postulate is a proposition (statement) taken as a given.  A lemma is an intermediate proposition or stepping stone rather than the final result, which is a theorem.  A corollary follows readily from a theorem—it’s often simply another way of stating the theorem.  Lemmas, theorems, and corollaries are all proven, but proofs are only possible within mathematics and logic, not within science.

By contrast, all scientific statements are provisional.  A scientific hypothesis is a testable explanation for a phenomenon.  It explains and predicts.  Once a hypothesis has proven itself, it becomes a scientific theory.  A scientific law is a description of a natural phenomenon, often an equation.  Laws and theories are both well-tested, widely or universally accepted within the field, and falsifiable.  The main difference is that a theory explains while a law describes.

For example, germ theory, quantum theory, and the theory of evolution are explanations.  Boyle’s law, Ohm’s law, and Newton’s law of gravity are all descriptions (and are all equations).

A common misconception is that scientific hypotheses mature to theories, which mature to facts or laws.  Instead, facts (the observations from an experiment, for example) lead to hypotheses (a plausible but immature explanation), which lead to theories (well-evidenced explanations).  In the category of scientific explanations, a theory is as good as it gets and it doesn’t graduate to become a law.

Don’t Like Abortion? Then Support Sex Education.

There’s a reality disconnect within the pro-life community. They reject abortion while they also reject the solution to abortion, sex education. Is abortion an American Holocaust, as Ray Comfort says? If so, then join forces with the pro-choice camp and teach teens how to avoid it!

Being against abortion but rejecting sex education is like being against deaths through unclean water but rejecting sewer systems.

Here’s an excellent infographic on sex education from PublicHealthDegree.com.  Pass it on.

It’s Funny Until Someone Gets Hurt, then it’s Hilarious

Creationists make themselves look foolish when they pick and choose their scienceI’ve been amazed at the popularity of Creationism/Intelligent Design among Christian pundits.

Old-earth Creationism accepts the consensus within the field of cosmology about the Big Bang and the formation of the solar system 4.6 billion years ago but rejects evolution.  Young-earth Creationism also rejects evolution and argues that the earth is less than 10,000 years old.  This view is predominant among evangelical pastors.

Dr. Karl Giberson recently pointed out an interesting downside of this mindless rejection of science.  He begins by citing a Barna survey that lists six reasons why most evangelical Christians disconnect from the church, at least temporarily, after age 15.  The most interesting reason: “Churches come across as antagonistic to science.”

Of the young adults surveyed,

  • 23% say they had “been turned off by the creation-versus-evolution debate”
  • 25% say “Christianity is anti-science”
  • 29% say “churches are out of step with the scientific world we live in”
  • 35% say “Christians are too confident they know all the answers”

As an example of this rejection of science, Giberson points to the technique recommended to schoolchildren by Creation Museum founder Ken Ham.  Ham encourages students to ask, “Were you there?” when the biology teacher says that life on earth appeared roughly 4 billion years ago or the physics teacher says that the Big Bang gave us the universe in its present form 13.7 billion years ago.

Ham proudly blogged about nine-year-old Emma B., who wrote to tell Ham how she attacked a curator’s statement that a moon rock was 3.75 billion years old with “Were you there?”

Biologist PZ Myers nicely deflated Ham’s anti-science question with a gentle reply to Emma B.  Myers recommends using instead “How do you know that?” which is a question from which you can actually learn something.

Contrast that with Ham’s “Were you there?” which is designed simply to shut down discussion and to which you already know the answer.

“Were you there?” is a subset of the more general question, “Did you experience this with your own senses?”  To Science, this question lost significance hundreds of years ago.  The days when Isaac Newton used taste as a tool to understand new chemicals are long gone.  Modern science relies heavily on instruments to reliably provide information about nature—from simple ones like compasses, voltmeters, and pH meters to complex ones like the Pioneer spacecraft, Hubble space telescope, and Large Hadron Collider.

Personal observation is often necessary (finding new animal species, for example), but this is no longer a requirement for obtaining credible scientific evidence.

From the standpoint of mainstream Christianity, Ham’s position as a young-earth Creationist and Bible literalist is a bit extreme, but higher profile figures like William Lane Craig also give themselves the option to pick and choose their science.  Craig uses science a lot—at least, when it suits his purposes.  The Big Bang suggests a beginning for the universe, so he takes that.  Evolution suggests that life on earth didn’t need God, so he rejects that bit.

He imagines that he’s Hanes Inspector Number 12: “It’s not science until I say it’s science.”  It may be fun to pretend that, but what could possibly make you think that’s justifiable?

That reminds me of a joke:

Scientists figure out how to duplicate abiogenesis (the process by which molecules became something that could evolve).  They are so excited that they email God to say they want to show him.  So God clears some time on his calendar and has them in.

“Sounds like you’ve been busy,” God said.  “Show me what you’ve got.”

“Okay—first you take some dirt,” said one of the scientists.

“Hold on,” God said.  “Get your own dirt.”

And to William Lane Craig’s pontificating about science, I say, “Hold on—get your own science.”

You either play by the rules of science and accept the scientific consensus whether it’s compatible with your preconceptions or not, or you sit at the children’s table.  If you want to hang out with the adults, you can’t invent reasons to rationalize why this science is valid and that is not.

Evangelicals may want to rethink this picking and choosing of science.  Giberson ends his article:

The dismissive and even hostile approach to science taken by evangelical leaders like Ken Ham accounts for the Barna finding above.  In the name of protecting Christianity from a secularism perceived as corrosive to the faith, the creationists are unwittingly driving the best and brightest evangelicals out of the church….  What remains after their exodus is an even more intellectually impoverished parallel culture, with even fewer resources to think about complex issues.

Perhaps I should be more welcoming to Christian anti-science in the future.

1906 San Francisco Earthquake and Fire

Cross Examined, a novel about Christian apologetics, Christianity, and atheism109-year-old Rose Cliver, the oldest survivor of San Francisco’s great earthquake, has recently died, leaving only two survivors of the event.  The Huffington Post article of the event includes some great photos of the aftermath.

While a little off-topic for this blog, this is squarely on topic for my book, set in 1906 Los Angeles in the aftermath of the earthquake.  The Azusa Street Revival, which launched the Pentecostal movement, began with a reasonably successful prediction on the front-page of the LA Times the morning of the earthquake.

Someone within the Azusa Street church saw the people of Los Angeles “flocking in a mighty stream to perdition” and saw “awful destruction to this city unless its citizens are brought to a belief in the tenets of the new faith.”

This was too cool an event to ignore, and I launched my story with this earthshaking and historic prediction.

16 Arguments Against Abortion, Addendum

Novel explores Christianity atheism apologetics themesThanks to the Prime Directive blog, I belatedly came across a long list of “Questions for Pro-Choice People” by Prof. Michael Pakaluk.  I’ve already responded to most of them with the spectrum argument, but here are three extra questions taken from this list that explore new ground and are worth highlighting.

17. Imagine a woman seeing an ultrasound of her unborn baby.  Sometimes the hands and feet are visible, and the baby is sometimes sucking its thumb.  Why aren’t such images shown to women considering abortions as part of informed consent?

Works for me.  But let’s add conditions to make this practical.

  • This should be an option rather than part of a mandatory gauntlet forced on women considering abortion.
  • This should not be the first time the woman has seen this information.  That is, education should teach about the stages of fetal development as part of comprehensive sex education that would minimize the chances of her having this unwanted pregnancy in the first place.
  • The woman’s choices should be made available as soon as possible.  Putting obstacles in her way—by closing down nearby clinics, encouraging pharmacists to refuse to offer morning-after pills, and so on—increases the age of the fetus she must consider aborting.  If an abortion is to happen, let’s make it early so that the woman doesn’t see a fetus sucking its thumb.

18. “Does anyone wish that his mother had chosen abortion for him? And, if not, then how can he consistently wish that any mother choose abortion for anyone else?”

This is a more eloquent version of my question 4, in an earlier post.

In the first place, if I’d been aborted, I wouldn’t be here to care.  In the second, this thinking isn’t far removed from the Quiverfull movement (my thoughts on that here), which encourages no restraint on birth and childishly “lets God decide” how many children to have.

Where do you draw the line?  If we are morally obliged to bring to term a 2-week-old fetus, are we also morally obliged to bring to term the thought, “Gee, I wonder if we should have another baby …”?

Seeing life as a spectrum is the only way to make sense of this.  Yes, that leaves unanswered the question of where to draw the line for abortion, but let’s first agree that a spectrum exists.

19. Let’s suppose that we’re doubtful that the unborn child is a human being with human rights (there is no doubt, but let’s imagine there is).  Given this uncertainty, shouldn’t we err on the side of the child?

I agree that there’s no doubt, but I’m sure my confidence is the opposite of yours.

A fetus is not a person.  Play games with the name all you want (“The fetus is a Homo sapiens, ‘human being’ is simply a synonym, and if a fetus is a human being, it must have human rights!”), but there’s no ambiguity here.  Despite your word games, a newborn baby is still not the same thing as a single cell.  There is a spectrum.

Word of the Day: Haggard’s Law

Christianity and atheism, does God exist?Rev. O’Neal Dozier, a Rick Santorum backer, says that homosexuality is the “paramount of sins” and that it is “something so nasty and disgusting that it makes God want to vomit.”

Pastor Ken Hutcherson, here in Seattle, is against Washington state’s new law-in-waiting allowing same-sex marriage.  He’s been riding this horse for years, ever since he complained about Microsoft offering health benefits to same-sex partners of employees.

Ted Haggard was the founder and former head of both the 10,000-member New Life Church and led the National Association of Evangelicals.  In the movie Jesus Camp, he said, “We don’t have to debate about what we should think about homosexual activity.  It’s written in the Bible.”

But Pastor Ted was brought low by claims that he had a long-term relationship with a gay prostitute.  This hypocrisy gave us Haggard’s Law: the likelihood of someone’s being gay increases in proportion to the force of that person’s public objections to homosexuality.  One wonders if the other pastors similarly doth protest too much.

The next time some guy with a religious or political platform bloviates about why a segment of society doesn’t deserve the same respect as everyone else, remember Haggard’s Law and wonder what he’s hiding.
