Sea anemones can swim!

April 23, 2013 • 10:02 am

Well, at least some of them. Matthew, our resident author, just called my attention to this video showing a sea anemone swimming to avoid predation. Although sea anemones are in the phylum Cnidaria along with jellyfish and box jellies, I’ve always thought of them as completely sessile.  Well, some of them are, but not all. This one takes off and starts swimming about 55 seconds in:

The YouTube notes give a bit more information:

Apparently a few species are permanently pelagic: not affixed to a substrate but floating freely in the water.

Matthew haz a new book!

April 23, 2013 • 8:30 am

Matthew Cobb has posted many times on this site, and I wanted to call attention to his new book—the third from his pen—that has just been published in the UK by Simon and Schuster.  Here’s the cover:

Nice cover photo, eh? And there’s lots of great photos inside.

There’s no U.S. deal yet, but interested readers in the U.S can still buy it (see below)! I recommend it, especially for WWII or Liberation buffs, as it’s a colorful story that draws heavily on first-person accounts. I read it in manuscript (and suggested some changes), and was deeply absorbed.

In a review by Max Hastings, The Sunday Times said: “The final days of the German occupation of the French capital are vividly captured in this fine account of death and deliverance” (full review here, but behind a paywall).

You can buy the book from Amazon.com here (Kindle only) and both hardback and e-book from Amazon.co.uk here (other booksellers are available – you might check the details on Amazon and then order it at your local bookstore!). U.S. readers can order from amazon.co.uk.

There’s also a website associated with the book, elevendaysinaugust.com, where you can find pictures of the dozens of diarists who were used to tell the story, as well as film and radio recordings from the time. A short promotional video will be on YouTube soon.

US readers can now pre-order Matthew’s previous book, The Resistance, here. And don’t forget his earlier book, The Egg and Sperm Race, on how 17th-century scientists figured out the way human reproduction works. That’s another good read!

Matthew is a scientist and a dean at Manchester, has a family consisting of spouse, two daughters, and two cats, teaches, does research, and manages to write books completely unrelated to his profession. I don’t know how he does it, but I’ll have what he’s having!

Prize-winning Templeton essay: death is good for humanity

April 23, 2013 • 6:16 am

Last August I wrote (critically, of course) about a $5 million grant given to the University of California at Riverside by the Templeton Foundation. The subject was “Immortality,” and the lucky recipient was philosophy professor John Fischer. If you read my earlier post on this, you’ll know that much of the Templeton money was earmarked for studying ludicrous questions, including whether near-death experiences give us plausible evidence for an afterlife (we already know the answer to that), and whether perpetual existence in an afterlife would be “repetitive or boring.”

This is what we’ve come to expect from Templeton. How much more good that money would do were it used to buy food for starving African children!

At any rate, UCR Today, the publicity organ of the University, announced yesterday that the Immortality Project has awarded its first essay prize to Steven Cave, a writer based in Berlin.  You can see his essay, called “Death: Why we should be grateful for it,” on the New Scientist website (why is it there?) for free until August, though you have to register (a simple procedure requiring your name, email, and a password). It was published last October.

Although I know there are some readers who don’t mind dying, I’m not one of them. When I read this essay, I immediately thought of two quotes from Woody Allen (I’m recalling these from memory):

“I don’t want to achieve immortality through my work—I want to achieve it by not dying.

and

“I don’t mind dying. I just don’t want to be there when it happens.”

Cave’s essay, however, is meant to make a virtue of this necessity. Death, he argues, is a good thing, and for numerous reasons. Well, maybe it’s good because when you’re old, decrepit, and ill, you are ready to go.  But in a world without death, that wouldn’t be the case, for death is the result of that decrepitude. (Cave doesn’t posit what shape we’d be in if we were immortal.)

Here are some of Cave’s arguments for why death is good (indented quotes are from the article):

. . . we work very hard to stave off death, to defy it for as long as possible or deny it altogether. All this frantic defiance and denial result in some of our greatest achievements.

This is perhaps most obvious when considering humanity’s material progress: agriculture, for example, was invented to give us the food we need to live. Clothes and buildings keep us warm and give us shelter, weapons allow us to hunt and defend ourselves, and medicine heals our sicknesses. The great majority of the material innovations that make up our civilisation are in essence life-extension technologies that we have been driven to invent by the spectre of oblivion.

Of all these achievements, perhaps the greatest is science. This, too, has always been motivated by the fear of death. Francis Bacon, the father of empiricism, described indefinite life extension as “the most noble goal”. He sacrificed his own life to the cause, dying of pneumonia contracted while attempting an experiment in cryopreservation involving a chicken and some snow. Science is the business of self-aware mortals – the gods would have no need of biochemistry.

This is almost religious in its blatant disregard of the facts. First of all, clothes, weapons, fire, buildings and agriculture weren’t contrived to stave off death, but to keep us comfortable. Those things would still have come about if we were immortal.  After all, who wants to spend eternity shivering and starving?

Yes, some medicine was contrived to stave off death, but if we didn’t have death, we wouldn’t need that kind of medicine! This is like saying that cancer is good because it enabled us to develop chemotherapy.

Further, a lot of medicine came from a wish to alleviate conditions that don’t kill us, like migraine headaches, sinus conditions, and the like.  As for the claim that “science. . has always been motivated by the fear of death,” that’s completely stupid.  Really? Did quantum mechanics come about from fear of death? The theory of evolution and of chemical bonds? Where does Cave get such an idea? Where is his evidence?

But there’s more. Death didn’t just give rise to science, but to civilization and culture, too!

. . . Despite the best efforts of science and technology and the very real improvements in life expectancy that they have achieved, the terrifying prospect of death still hangs over us. That is why humans invented culture as well as material civilisation. Many thinkers, from Georg Hegel to Martin Heidegger, have suggested that its purpose is to reassure us that even though the body will fail, we will still live on.

Who is he kidding? Yes, as Cave notes, some people create in the hopes of immortality, but there are many other reasons for producing culture, including the simple need for self-expression.  I doubt that the majority of artists or composers are driven more by the desire to leave something that will outlive them than to leave something that expresses their feelings and can be appreciated by their contemporaries.  After all, when you’re dead you don’t experience any approbation! Does Cave seriously think that if we were immortal that there would be no civilization?

There is one part of the argument (not considered by the author) that may be true. If we were immortal, we wouldn’t have evolved into humans unless we had children, and natural selection for bigger brains—and hence culture—would have been much more difficult without differential mortality, i.e., death. There still would have been selection via differential fertility, of course, but even then the world would fill up with people and we’d all die. In that sense, and that sense alone, death is good for our species. But Cave doesn’t take this critical issue on board.

And there’s another elephant in the room: for many, the main motivation for religion is bodily death and the attendant hope that we’ll live on plucking our harps on a cloud. The knowledge that our physical death would produce an afterlife was a motivation, for instance, for the 9/11 episode.  But somehow Cave manages to convert this into a positive, for afterlife isn’t what comes after our physical death, it is “the denial of death”:

. . . in over 400 studies, psychologists have shown that almost all aspects of our various world views are motivated by our attempt to come to terms with death. Nationalism, for example, allows us to believe we can live on as part of a greater whole. Sure enough, Greenberg and colleagues found that US students were much more critical of an anti-American writer after being reminded of their mortality. A further study, by Holly McGregor at the University of Arizona, showed that students prompted to think about death were not merely disapproving of those who challenged their world views, but willing to do violence to them in the form of giving them excessively large amounts of hot sauce (Journal of Personality and Social Psychology, vol 74, p 590).

These initial studies supported Becker’s bleak view that the denial of death is the route of all evil. It causes the creation of in-groups and out-groups, fosters prejudice and aggression, and stokes up support for wars and terrorism.

Of course, if we were immortal there would be no need to attack other people, for you couldn’t kill them! (If Cave thinks that we’d be naturally immortal, but still subject to death by violence, he doesn’t say so.) It is the realization of death, and the need to continue life on some other plane, that motivates religion.  Were we immortal, I doubt we’d be so religious.

Cave goes on to tout the Pyramids and other touristic tombs as benefits of death, but really, if I could live forever, I’d gladly do without the Pyramids—though I’d miss the Taj Mahal.

Finally, and, as an evolutionary biologist, I find this to be the most ludicrous argument: Cave claims that our desire to reproduce stems from our fear of death. Having kids is a “terror management strategy”, giving us solace that we will live on through our children:

Socrates saw this 2000 years ago, arguing that much of what men do can be understood as a desperate attempt to immortalise themselves; women, he thought, could take the more direct route of having children. Several studies suggest he was right to see founding a family as a terror management strategy: one showed that German volunteers expressed a greater desire to have children when reminded of death; another that Chinese participants were more likely to oppose their country’s one child policy when similarly primed.

There’s one problem with this: animals and plants, who don’t know they’re going to die, have precisely the same drive to reproduce. This, of course, is the sine qua non of natural selection: it gives us the drive to reproduce because genes that promote such drives—and of course they needn’t operate through conscious knowledge—are those genes that persist.  How much of our desire to have kids is based on our conscious knowledge of mortality, and how much is from our instinctive desire to reproduce, instilled by evolution, that is simply reified through consciousness? After all, many of our “conscious” decisions may simply be mental confabulations of things that our genes have already compelled us to do.

Cave ends up with a truly Templetonian positive conclusion:

Conscious death reminders, on the other hand, stimulate a more considered response, leading people to re-evaluate what really matters. The more we actively contemplate mortality, the more we reject socially imposed goals such as wealth or fame and focus instead on personal growth or the cultivation of positive relationships.

Orly? It seems to me that atheists are the ones who would be most likely to reject things like wealth and fame in favor of more meaningful goals. Does Cave really think that, in a world of immortals, we would strive far more avidly for wealth and fame than we do already.

There may be a good essay to be written on this topic, but Cave’s isn’t it.  He doesn’t lay out the conditions of immortality, specify whether we could still be killed or grow feeble, or discuss the implications for natural selection.  He ignores the fact that consciousness of mortality probably plays little role in our drive to reproduce, nor whether that drive is even a good thing in today’s overcrowded world. Finally, Cave doesn’t adduce the slightest bit of evidence that science, civilization, and culture spring largely from fear of death.

I don’t know how much money Cave got for his prize, but I suspect that, given Templeton’s largesse, it’s substantial. I look forward to further essays on why cancer, tsunamis, and strokes are good.  Thank the Lord that He gave us death! That, after all, is probably the hidden Templetonian message behind the prize.

Richie Havens died

April 23, 2013 • 4:45 am

Singer Richie Havens (b. 1941) died yesterday of a heart attack at age 72.  To many of us who grew up in the Sixties, he was an iconic folk singer—not wildly popular, but immensely talented and certainly not obscure.  He first gained fame as the opening act of the Woodstock Music Festival in 1969 (I have his autograph, along with several other performers, on an original Woodstock poster I won in a contest).  Here’s the Wikipedia note about how he came to everyone’s notice, and I follow it with the video of that fantastic performance:

Havens’ reputation as a live performer earned him widespread notice. His Woodstock appearance proved to be a major turning point in his career.  As the festival’s first performer, he held the crowd for nearly three hours (in part because he was told to perform a lengthy set because many artists were delayed in reaching the festival location), and he was called back for several encores. Having run out of tunes, he improvised a song based on the old spiritual “Motherless Child” that became “Freedom”. The subsequent Woodstock movie release helped Havens reach a worldwide audience. He also appeared at the Isle of Wight Festival in late August 1969.

If you look closely, you might notice that he’s missing all of his top teeth in this video. As I recall, he had them replaced later, dispelling the rumor that his unique voice was due to his partial toothlessness.

Havens continued touring and performing (my sister, a big fan, saw him a gazillion times) until he retired last year because of health issues.

Another gem from Havens is his complete reworking of the Beatles’ “Here Comes the Sun.”

Here’s how I remember him:

Islam apparently behind Boston bombing

April 22, 2013 • 6:52 pm

Virtually all godless bloggers held their tongues after the Boston bombing, despite the fact that all the accommodationists and criers of “Islamophobia” wanted us to blame Islam from the get-go.  But that was simply not rational given the attacks of people like Timothy McVeigh, the Unaibomber, and Eric Rudolph, the guy who set off the bombs at the 1996 Olympics. We withheld judgement.

Yes, most of us suspected that extremist Islam might be behind the bombings, a suspicion buttressed by yesterday’s revelation that two Canadian residents were arrested in an Al-Qaeda-linked plot to blow up trains running between Toronto and New York City.

Well, Islam now seems to really be behind what happened in Boston. According to my news feed from CNN:

Boston bombings suspect Dzhokhar Tsarnaev conveyed to investigators that no international terrorist groups were behind the attacks, a U.S. government source told CNN’s Jake Tapper.

Dzhokhar Tsarnaev indicated his older brother, Tamerlan, was the driving force behind the attacks and wanted to defend Islam from attack, the source said.

The 19-year-old was “alert, mentally competent and lucid,” U.S. Magistrate Judge Marianne Bowler found during a brief initial court appearance in Tsarnaev’s hospital room. During the hearing, he communicated mostly by nodding his head.

How many times do we have to learn this lesson? By all accounts the Tsarnaev brothers were creditable students, good athletes, and seemingly nice people.  That is, of course, until they fell into the grips of Islam. As Steve Weinberg says, “For good people to do evil things—that takes religion.”

It’s only a matter of time before the faitheists and apologists start clamoring that what was really behind the attacks was politics and Western imperialism—anything but faith.  We should start taking these terrorists at their word instead of confecting soothing reasons why religion wasn’t to blame.

Kansas public school mandates “Creation Truth Foundation” assemblies

April 22, 2013 • 12:54 pm

by Greg Mayer

According to The Raw Story,

Hugoton [Kansas] Public Schools invited Creation Truth Foundation’s founder Dr. G. Thomas Sharp to teach the “Truth about Dinosaurs” at two assemblies next week. At least one of the assemblies will be mandatory for all students and teachers.

You’ve probably never heard of the Creation Truth Foundation or its founder, but you’ll learn all you need to know about them within the first 30 seconds or so of this video:

The ACLU has rather gently told them to cut it out, pointing out that the courts have repeatedly held that teaching religious beliefs as science, no matter how you try to hide it, is unlawful. The brand of religion trumpeted by Sharp, unlike that promoted by intelligent design creationists, isn’t the least bit hidden; from their website:

Creation Truth Foundation has many programs, presentations, books and videos that can effectively edify the faith of your church family. Our President, Dr. G. Thomas Sharp, has spoken in ten different countries, and all across the United States in revival meetings, church camps, conferences and educational forums.

His expertise in apologetics especially based in Genesis has been used in colleges, universities, television and radio programs as well as preschools and kindergartens. You will be excited to have him come to your church family with either one of his many presentations about Biblical Creation, or the Biblical Family.

CTF also has a remarkably exciting program that has been seen by more than 115,000 since September of 1998. This program called The Truth About Dinosaurs is presented in the company of twenty-eight of the world’s most exciting fossils. This is a must have for churches across the U. S.! …

Creation Truth Foundation has a host of support materials and services to aid your delivery of a sound science curriculum based in Biblical Creation. The Truth About Dinosaurs program is an excitingly spectacular presentation of the Biblical view explaining the origins, extinction and possible existence of dinosaurs.

Incredibly, the school superintendent insists that the program will be, “completely and totally school appropriate.” I’ll keep an eye out for the results of legal action.

(Note for UK readers: “public schools” are state-supported schools, subject to the Constitutional mandate of non-establishment of religion.)

Patient like a hunter: taking pictures of Earth from space

April 22, 2013 • 12:04 pm

by Matthew Cobb

If you are on any social media, especially Twitter, you will probably have come across Commander Chris Hadfield (@Cmdr_Hadfield on Twitter) the Canadian who is in charge of Earth’s very own spaceship, the International Space Station. He has been tweeting from space (TWEETING FROM SPACE!) and in particular has been taking pictures of Earth, some of which have featured on WEIT. He has photographed most of Earth’s major cities at night (we had Manchester the other week). In this video Commander Hadfield explains how he takes his pictures from the ISS. Includes both lots of lovely pics, and suitably nerdy camera-speak for those of you who are into F-stops and ISOs.

Oh, and if you want to wave at the ISS as it zooms over your part of Earth (it is an amazing sight), go here and select your country from the drop-down menu on the left. Click through and you’ll eventually get information for your location.

Andrew Brown plays the Islamophobia card

April 22, 2013 • 10:33 am

Poor Andrew Brown!  He got left behind in the salvo of “Islamophobia” accusations leveled by his fellow journalists against the New Atheists.  To make up for it, he has an especially nasty post in today’s Guardian, with the headling “Richard Dawkins’ latest anti-Muslim Twitter spat lays bare his hypocrisy” (Subtitle: “The celebrity atheist’s Twitter rant against journalist Mehdi Hasan shows he’s a believer too – in his own mythology.”)

The piece is mercifully short, and about what one would expect from Brown: completely idiotic.  Here’s Brown’s opening; notice that it’s strident, militant, and far from humble: all the things that he and his ilk accuse the New Atheists of being:

Richard Dawkins and Twitter make one of the world’s great pairings, like face and custard pie. But whereas more accomplished clowns ram custard pies into the faces of their enemies, Dawkins’ technique is to ram his own face into the custard pie, repeatedly. I suppose it saves time and it’s a lot of fun to watch. On Sunday afternoon he was at it again, wondering why the New Statesman employs an imaginative and believing Muslim:

[Dawkins’s tweet}: “Mehdi Hasan admits to believing Muhamed [sic] flew to heaven on a winged horse. And New Statesman sees fit to print him as a serious journalist.”

That seems fair enough to me. It’s not just that Hasan keeps these beliefs private, but makes them in public, which does bring into question his objectivity on certain points. Truly, to believe that Mohamed flew to heaven on a horse is delusional, and to say that in public, in a debate with Dawkins, is downright embarrassing. It’s as if Paul Krugman were to confess that he thought that God had two bears kill 42 children because they made fun of the prophet Elisha’s bald head. Of course it’s bigotry to fire a journalist for being religious, but it’s certainly kosher to criticize an employed journalist and wonder why such a delusional firebrand is gainfully employed at a reputable paper.

Brown, lacking much ammunition, then belabors Dawkins for a perfectly normal exchange of tweets with an MP

For instance, Tom Watson, the MP who pursued Murdoch, tweeted back almost at once: “You really are a gratuitously unpleasant man”. To this Dawkins replied “Actually no. Just frank. You’d ridicule palpably absurd beliefs of any other kind. Why make an exception for religion?”

“You are gratuitously unpleasant; I am just frank” comes straight out of the Yes Minister catechism of irregular verbs.

But it gets better. Dawkins continues: “A believes in fairies. B believes in winged horses. Criticise A and you’re rational. Criticise B and you’re a bigoted racist Islamophobe.” It is of course horribly unfair to call Dawkins a bigoted racist Islamophobe. Anyone who follows him knows he is an equal opportunities bigot who is opposed to Christians of every colour as well.

Richard’s statements all seem quite reasonable to me; he doesn’t respond to Watson in kind, but makes a substantive point: that, unlike other delusions, religious beliefs get a pass in British society.  And, once again, the charge of “bigot” is leveled at anyone who dare criticize religious beliefs.

In the end, Brown’s reduced to calling Dawkins a hypocrite, equating Richard’s questioning of Hasan’s stature (in a tweet, for crying out loud!) with Hasan’s delusional beliefs:

. . . us inferior, less rational types can easily suppose that he means what he says, and that therefore he does think that Muslims, especially proselytising ones like Mehdi Hasan, are spreading evil and should not be employed by respectable magazines.

Of course Dawkins would probably deny with complete sincerity that this is what he means – until the next time he says it. This doesn’t make him unusually hypocritical. It just means that he thinks the same way as people who believe stories that are differently ridiculous to his – that the twelfth imam will return, or that Muhammad ascended to heaven on a winged horse.

Leaving aside the false claim that Hasan spreads evil, and that he should be fired by the New Statesman (is criticism the same as a call for firing?), how can Brown possibly equate a passionate but rational tweet with a passionate and completely delusional set of beliefs.  “Ridiculous” is not the issue: truth is.

Sometimes I wonder why I waste my time on Andrew Brown, and I always tell myself it’s for the same reason that I smell the milk when I know it’s already gone bad. This is what Brown is reduced to: trolling someone’s Twitter feed.
