Flat Earth Debate

I injected myself into an on-line discussion recently, and decided I'd post the pertinent parts of that discussion here, mainly for posterity, but also for hilarity.

The discussion centered around the question of whether the Bible's authors thought the Earth was flat or not. The outstanding statement on the table was the following:

My Opponent: "the Bible actually states the Earth is round not flat"

So, I responded with the following:

Me: "Round doesn't mean not flat, whereas sphere or ball does. The Ancient Hebrews had a word for sphere, which is equivalent to our word for ball. They didn't use that word to describe the Earth though, choosing instead to use the Hebrew word for round. This usage by itself suggests they were referring to a flat Earth. But in addition to that, there are also biblical references to events taking place at the center of the Earth, which can only mean a flat Earth, since a spherical object has no center on its surface. So, unless you're willing to accept that these events took place literlly in the middle of our spherical Earth, you'll have to concede that the authors were referring to a flat Earth."

This comment should have technically ended the discussion, unless my opponent could show that I was wrong, that ancient Hebrew actually used the same word for round and sphere or something like that, but he had a different, more nonsensical angle:

My Opponent: "something round CANNOT be flat too"

Wow. The word CANNOT really jumps out doesn't it? Obviously his way of puffing out his chest with confidence. Clearly he felt he was making a point that should be pretty obvious, but, as you'll soon see, he couldn't have been farther from the mark. In fact, his response reminded me of another debate.

Some years ago, I heard of a now infamous debate, where a creationist tried to argue that evolution couldn't be true, because if it were, it would violate the second law of thermodynamics. This is of course false, but that's not what makes the story interesting. The creationist in that debate made this argument:

One of the most basic laws in the universe is the Second Law of Thermodynamics. This states that as time goes by, entropy in an environment will increase. Evolution argues differently against a law that is accepted EVERYWHERE BY EVERYONE. Evolution says that we started out simple, and over time became more complex. That just isn't possible: UNLESS there is a giant outside source of energy supplying the Earth with huge amounts of energy. If there were such a source, scientists would certainly know about it.

The money quote of course is the reference by the creationist to a "a giant outside source of energy supplying the Earth with huge amounts of energy". I can only imagine how foolish he must have felt when it was explained to him that this giant energy source exists, and has a very familiar name.

It's called the SUN!! [tremendous howls of laughter ensue]

Anyway, I got to have my "it's called the Sun" moment when I responded this way:

Me: "Ever heard of pizza?"

I thought it was a pretty funny response, and figured that after such a humiliating defeat, he'd concede the point and we could go on with our lives. But no, this guy wasn't giving up, he'd lost the battle, but he was still wanting to win the war. His confidence was fading though, he no longer seemed as confident about his initial claim:

My Opponent: "The Bible meant the center of the known world, they didn't know about the rest of the world yet."

So, in a matter of minutes, his argument goes from a confident "they knew what shape the Earth was!", to a timid "umm, they had no idea."

Well, Okee Dokee.

So, I responded with the following, which turned out to be the debate killer. There was no further response:

Me: "Don't you find it odd that people who were supposedly guided by the divine inspiration of an all knowing super entity, were restricted in their knowledge to the same things we would expect of people who weren't guided by the divine inspiration of an all knowing super entity? Hmmm."

I hope that one didn't make him cry.

Defining Science

In the January edition of Evolution: Education and Outreach is an article called What's So Special About Science? It was written by Ian Tattersall and does an absolutely fabulous job defining science.

Here are some excerpts from the article:

All any honest scientist is really trying to do is to approximate the truth, in the realization that ultimate truth is unknowable through scientific means and that the knowledge he or she generates is invariably susceptible to modification.

...the core of the scientific endeavor amounts simply to the corporate effort to describe nature and its workings as accurately as possible.

What matters is that science as a whole is a self-correcting mechanism in which both new and old notions are constantly under scrutiny.

For this system of provisional knowledge to work, it is necessary that, to the extent possible, scientific hypotheses be proposed in such a way that they are at least potentially falsifiable-provable to be wrong.


Essentially, to understand science, there are two very important concepts:

1) Falsifiability

Science cannot prove, only disprove. When a hypothesis contradicts observations, then it's disproven; if it agrees with the observations made thus far, it's not disproven. Science doesn't search for truth, because we can never be certain that future observations won't disprove what we currently believe to be true. And even if we thought we could search for truth, how would we verify it? We couldn't compare it to the truth, since we don't have the truth, therefore TRUTH falls outside the bounds of science.

Hypotheses that include the workings of sufficiently ineffable deities are useless to science, since they cannot be falsified. You are only doing science when you can answer the question "If I were wrong, how would I know?". When you can't answer that question, you aren't doing science.

2) Occam's Razor: the principle of parsimony

When there are multiple hypotheses that explain our observations equally (meaning our hypotheses have not been disproven) then scientists will choose the simplest one (meaning the one that requires the fewest additional assumptions).

Texas Academy Statement Against Teaching Creationism or Intelligent Design in Science Classes

The Texas Academy of Science issued this statement defining their position against the inclusion of creationism or intelligent design in science classrooms. Here's an excerpt:

"It is the postition of the Texas Academy of Science that because neither creationism nor intelligent design are based on information obtained using scientific methodologies, and because neither has withstood the test of scientific peer review, they are not scientific concepts. It is critically important to recognize that neither of these concepts is falsifiable. Having failed the scientific verification process, both must be excluded from scientific curricula at the primary, secondary and higher education levels. This is not just the position of the Texas Academy of Science, it is the consensus of the U. S. Supreme Court, Judge John E. Jones in Kitzmiller vs. Dover (2004) and 11,000 plus Christian clergy signers of the Clergy Letter Project. Other scientific organizations throughout the United States have formulated position statements calling for the exclusion of creationism and intelligent design from science curricula, including the American Association for the Advancement of Science; the National Academies of Sciences, Engineering, and Medicine; the National Research Council; the National Center for Science Education; the National Science Teachers Association; the National Association of Biology Teachers; the Geological Society of America; and the American Geological Institute. It is the overwhelming consensus of the scientific community that creationism and intelligent design are faith-based concepts that have no scientific merit."

Scathing Editorial

Editor Marshall Helmberger wrote a scathing editorial in the Timberjay about common creationist tactics. It's an informative read, one that should be read by school board members across this country. Here's a small sample:

"Creationist advocates clearly had a sympathetic judge in the Dover case. They had their day in court, but their arguments were so patently flawed that the judge’s 139-page finding of fact was ultimately scathing. He even recommended some of the pro-creationism school board members be investigated for perjury."

Debate or Massacre?

PZ Myers of Pharyngula agreed to debate Geoffrey Simmons, a senior Fellow from the Discovery Institute, and the outcome was rather predictable. Here's a link to the audio, and here's a link to what PZ had to say afterwords.

I think the debate can be summed up best with these words from PZ:

"This is a man who thinks the fact that he isn't drooling and feces aren't dribbling down his leg is a miracle from god. After reading his book, I kind of agree."

What a hoot!

Success in South Carolina

With the help of Biologist and Author Kenneth Miller, defenders of science and reason scored a victory in South Carolina. Here's a link to some videos of Dr Miller and others defending the use of a textbook containing (gasp!) Evolution.

Notice in the first video that some of the board members actually voted against Dr Miller being given an additional 60 seconds to make his case. Pathetic!

For additional enjoyment, here is a link to the criticisms Dr Miller is referring to, as well as his responses. The critics never stood a chance :)
