Wright/Harris debate

October 10, 2010 • 8:35 am

Thanks to alert reader “ennui”, I’m able to post the video of yesterday’s debate between Robert Wright and Sam Harris at the Secular Humanism conference in L.A.

Another religion quiz

October 10, 2010 • 4:50 am

This time it’s in the New York Times, and it’s a 13-question multiple choice quiz by Nicholas Kristof. You’ll get where he’s going from the very first question:

1. Which holy book stipulates that a girl who does not bleed on her wedding night should be stoned to death?
a. Koran
b. Old Testament
c. (Hindu) Upanishads

His aim in making this thing?

And yes, the point of this little quiz is that religion is more complicated than it sometimes seems, and that we should be wary of rushing to inflammatory conclusions about any faith, especially based on cherry-picking texts. The most crucial element is perhaps not what is in our scriptures, but what is in our hearts.

What it really does, though, is show that religious dogma is bad, and this isn’t the first time Kristof has made that point.

Moar on the Smithsonian’s human evolution exhibit

October 10, 2010 • 4:47 am

In March the Smithsonian Museum of Natural History in Washington D.C. opened the David H. Koch Hall of Human Origins.  Last week Greg Mayer wrote a comprehensive review, pointing out the good and bad aspects of the exhibit.  I offer here a short supplement giving some highlights and lowlights. And let’s face it: any evolutionist is going to be critical of somebody else’s exhibit!

First, the entrance to the hall is, um, unprepossessing (as always, clicking on the photos will enlarge them):

A video exhibit near the entrance has both good and bad stuff. The exposition of the word “theory” is pretty good:

And so is the theme of exhibit, which is this: “how do we know what we say we know?”  This emphasis on evidence is estimable but, as Greg pointed out, the answers are provided not by the scientists who made the exhibit but by the viewer herself.  This exhibit of skulls has that postmodern fill-in-the-blanks air about it:

Close by is the hominin family tree. Note that it’s a branching bush, which is good, but it also puts the australopithecines off by themselves and not as the ancestors of Homo.  Unless there’s been some paleoanthropological advance of which I’m not aware, I think this question is unresolved, and maybe a question mark would have been better:

Here’s a life-size cast of the “hobbit,” Homo floresiensis, which may have lived as recently as 12,000 years ago.  Although its status as a species is controversial, evidence is slowly accumulating that hobbits were a genuine relict population of hominins.  And they were tiny: a bit more than three feet tall. Here I am standing next to one:

Our genetic similarity to chimps, our closest living relative, is a statistic that’s often abused.  The “99% identity” refers to the probability of identity at each nucleotide site in the DNA.  But since each gene comprises many nucleotide sites, the probability that a given gene has identical DNA sequences in humans and chimps is much lower.  In WEIT, I show that about 80% of all the proteins shared by the two species differ by at least one amino acid.  Depending on how you calculate the statistics, then, you can make humans and chimps look either 99% identical or only 20% identical.  The Smithsonian exhibit isn’t clear on this point.

For me, the most annoying part of the exhibit was this purported explanation of how evolution works.  It simply equates evolution to natural selection.  And of course natural selection is only one of several processes that can cause evolutionary change (genetic drift, the random change of gene frequencies due to sampling error, is another big one):

So, when viewers were urged to submit questions to the curators and other viewers, I typed in this one. Larry Moran is gonna love me!

All in all, I’d give the exhibit the grade of B, or even a B-. There are simply too many questionable assertions presented as fact, too many errors, and too much pandering to religion and political correctness (a video near the end asserts that human “races” don’t exist). But I’m a petulant evolutionist, and urge everyone, scientist and layperson alike, to visit this exhibit, if for no other reason than to see the remains and artifacts of our ancestors.

The bucket list: Angel Falls

October 9, 2010 • 10:42 am

At 979 meters (3212 feet—more than twice as high as the Empire State Building), Angel Falls is the tallest waterfall in the world.  (It’s unipartite, so it won’t inspire thoughts of Jesus.) Located in a remote part of Venezuela, it’s difficult of access but—along with petting a baby tiger—it’s definitely on my bucket list.  Here’s a gorgeous panoramic picture (single-click on it twice in succession to see the full splendor:

Here’s another view (again, click to enlarge):

And a wonderful video:

Here are ten things on my bucket list that I’ve done:

Hiked to Mt. Everest

Seen the Taj Mahal

Visited Machu Picchu

Hiked to the Annapurnas

Lived in Paris

Flown over the Nazca Lines in Peru in a small plane

Visited the Galápagos

Flown to Mount McKinley

Visited Beijing and saw the embalmed body of Mao

Visited Lhasa in Tibet and toured the Potala

And ten things I have yet to do:

Visit all 50 states (I’ve been to 49; only North Dakota remains)

Visit Angel Falls

Hold a baby tiger

Visit Bhutan

Skydive

Take a long trip through Australia

See a kakapo in New Zealand

Visit Antarctica and see the penguins

Visit South Africa and see the big game

Go to the Hermitage in Leningrad

What’s on your bucket list?  And what used to be before you did it?

The week’s worst defense of religion

October 9, 2010 • 5:12 am

From Uncle Karl, who finds it hypocritical for atheists to attack the regular-Joe believer, since his is a diluted and distorted version of the real faith—the faith espoused by theologians:

The second straw man I want to dismantle is the naïve “believer” that Coyne insists represents religion. Like Dawkins in The God Delusion and other New Atheists in their various screeds Coyne seems to think that the “majority view” held by uninformed believers with a haphazard collection of ideas from Sunday School is the true definition of religion. The religious ideas of these believers are then contrasted with the scientific beliefs of well-educated scientists. And—big surprise—they don’t fare too well in the comparison. . .

Let us suppose by analogy that we attached the label “science believer” to everyone who passes the standard roster of science courses in high school and affirms that, in general, they accepted what was taught in those courses. Now we have a group that is genuinely analogous to “religious believers.” Suppose now that a well-educated theologian was describing the beliefs of these “science believers,” and using the results to evaluate the credibility of science. The theologian would note that these people really were “believers.” They loved their iPhones and thought highly of the engineers and scientists who made them possible. They are excited about space travel and encountering aliens some day. When they get sick, they look to medical science for help. Sometimes they watch the Discovery Channel and they all loved Avatar.

But what would “science” look like, were it defined by these “believers”? From actual polls and other sources we know that the physics would be an incoherent mix of Aristotelian and Newtonian ideas; most of them would accept astrology and think that a “dowser” with a stick should be consulted before you drilled a well. UFOs and aliens would be accepted as real; some would report having been abducted by aliens. General Relativity, the most important theory in cosmology, would be completely unknown; quantum mechanics would be perceived as a way to influence the world with your mind and the scientific proof of free will.

Suppose that Keith Ward or Alister McGrath critiqued the scientific community for the collection of irresponsible things accepted by their followers, the “science believers.” Suppose they wrote books with titles like “The Science Delusion,” “Science is Not Great,” and “How Science Ruins Everything”? Coyne and company would cry foul immediately and say that the “science believers” were not authentic representatives of science, because they didn’t understand it very well.

And yet all of the “science believers” would have had far more education in science than the typical religious believer has in theology. Science as “lived and practiced by real people” is quite different than the science promoted by the intellectuals like Coyne and Dawkins.

Yes, but these “science believers” don’t cause problems.  In contrast, the “typical religious believers”—and not the sophisticated theologians—are the ones suppressing women and gays, taking all the fun out of sex for everyone, preventing the distribution of condoms to prevent AIDS, stoning adulterers and burning witches, filling young kids with Catholic guilt and fear of hell, fighting stem-cell research and the teaching of evolution in schools—and dividing human from human through irrational superstition.  People who misunderstand quantum mechanics don’t disenfranchise gay people or fly planes into buildings.

Most lyrical quote ever given to a newspaper

October 8, 2010 • 7:33 pm

Move over, Thomas Wolfe!  Here, as the final sentences in a New York Times story about noisy wind turbines, for God’s sake, is a quote of ineffably purple lyricism.  Cheryl Lindgren of Maine mourns the silence lost to her when they turned on the turbines:

But that is cold comfort for Mrs. Lindgren and her neighbors, who say their corner of the island will never be the same.

“I remember the sound of silence so palpable, so merciless in its depths, that you could almost feel your heart stop in sympathy,” she said. “Now we are prisoners of sonic effluence. I grieve for the past.”

Give that woman a book contract!
