Saturday: Hili dialogue

May 23, 2015 • 5:08 am

It’s Memorial Weekend in America, with all U.S.ers getting a three-day weekend (that doesn’t apply, of course, to Professor Ceiling Cat, who has important Cat Stuff to do).  There is food to buy, talks to write (Vancouver, Toronto, and D.C., all different), wine to pick up, and H is for Hawk to read.  I am also receiving emails telling me that I have got religion all wrong in my new book, but those will go into the e-circular bin. Meanwhile in Dobrzyn, Hili is blocking the entrance to the kitchen, probably so nobody can get noms without her knowing!

A: Hili, you are inconveniencing everybody.
Hili: Sorry for any inconvenience.

P1020780

In Polish:
Ja: Hili, przeszkadzasz tu wszystkim.
Hili: Przepraszam za niedogodność.

Neil deGrasse Tyson on science/religion accommodationism

May 22, 2015 • 3:07 pm

Apropos today’s discussion on reddit and my post about the conflict between science and religion, I came across this 11-minute discussion between Bill Moyers and Neil DeGrasse Tyson about that conflict. Tyson is far harder on religion, and far more insistent on the incompatibility between scientific and religious claims, than I’ve seen before. (Moyers clearly has a weakness for faith.) At 3:08, Tyson says he doesn’t think faith and science are reconcilable—that every effort to reconcile them has failed. He adds that he has “zero confidence” that anything fruitful will emerge from efforts to effect such a reconciliation.

My only disagreement with Tyson here is that he characterizes all creationists as “fundamentalists”, and not “enlightened religious people.” He’s talking about a minimum of 42% of Americans, and a maximum of 73%. I doubt that even 40% of Americans would characterize themselves as fundamentalists! Also, Tyson seems overly concerned with creationism as the predominant danger of faith, while I see many other dangers—some far more harmful than simply teaching creationism in the science class. In general, though, Tyson presents strong opinions in an eloquent way. His discussion of god-of-the-gaps arguments starting at 8:30 is very good.

Maybe if I get a vest with stars on it I’ll be seen as less strident!

Lessons from a talk

May 22, 2015 • 10:15 am

Yesterday I gave a 45-minute talk on Faith versus Fact at the University Club of Chicago, a ritzy venue akin to a British club. (There is a library, places to eat, and hotel-like rooms for members and their guests.) To its credit, the Club sponsors occasional talks on books. The talk I gave was a modified version of my “science versus theology” lecture, and although I didn’t get through everything I wanted to say, I think the talk itself went fine, and the audience seemed absorbed.

But during  the long Q&A afterwards, I realized that I will face considerable pushback from believers about this book. I realized that already on some level, but this is the first time I’ve discussed the book in front of a general audience instead of an overtly secular one. The audience (about 50, I think—the small room was full) was older, with most of people looking prosperous (joining the club is costly, though there were a few nonmembers who bought tickets), with most dressed better than I! (I was wearing a jacket, but not a suit.)

What surprised me was the large number of religious believers in the audience, how vociferous they were, and how eager they were to challenge science by raising God-of-the gaps arguments. Let’s take the last issue first.

Here are the challenges I got from some in the audience, all of which involve the interstices of our scientific understanding as evidence for God.

I was told that scientists are unable to explain the origin of living creatures, and even if we could explain the origin of replicating molecules, we still can’t explain how they evolved into creatures that “eat and poop.”  In response, I briefly drew out a scenario in which chemical evolution of molecules could lead to primitive replicating molecules, and then to cells and multicellular organisms, and noted that thinking that early “organisms” were just like modern ones was a fallacy. My argument was that organisms and life are a more or less arbitrary point in the transition from chemical evolution to biological evolution. The gentleman who made this argument did not listen to this response, but kept repeating his argument with a triumphant tone. The argument “you can’t explain this to my satisfaction, ergo God,” is of course fallacious, but it disturbs me to see it so often.

The “fine tuning” of the universe can be explained only by God, one man told me. I explained several alternatives, including the multiverse theory, but that explanation was discarded because, my interlocutor said, that’s simply the tactic of atheistic physicists determined to keep God out of the picture. My response–that the multiverse idea grew out of already-existing views of physics, for which there is some evidence, was also ignored.  The questioner was apparently unacquainted with the various scientific explanations for fine-tuning, and I recommended that he read the posts and books of Sean Carroll.

I was told by another person that the Big Bang could not be explained by the laws of physics, and that God’s creation was a more reasonable explanation. My response was that we can understand how, at least in a quantum vacuum, a universe could originate, and whether a quantum vacuum was “nothing” is a judgement call. I was then accused of giving a fanciful explanation for which there were no data. My response—that we do see particles pop into and out of existence, something required for “a universe from nothing”—was ignored. (I also responded that the origin of God also needs an explanation.) There was a pattern developing: people had heard “scientific” evidence for God, and were determined to ignore more naturalistic explanations.

Finally, someone said that we have no evidence that humans descended from apes. I said that we have plenty of evidence for that from both the fossil record and genetics, and recommended that the questioner read the “human evolution” section of WEIT. Remember that these people are certainly not Biblical literalists.

I was surprised, then, to find well-off and educated folks not only ignoring my responses, but determined to believe that God can be found in the phenomena science can’t explain.  In other words, at least among those at my talk, god-of-the-gaps arguments were pervasive—and convincing. I had explained in my talk the number of Biblical claims that science had already disproved, and how evolution replaced creationism as the best explanation for plant and animal “design”, so people should have been aware of the dangers of using god-of-the-gaps arguments. My further attempt to explain how science has, one by one, closed these gaps, was simply ignored. I would liked to have used this lovely quote from Robert G. Ingersoll’s On the Gods and Other Essays:

“No one infers a god from the simple, from the known, from what is understood, but from the complex, from the unknown, and incomprehensible. Our ignorance is God; what we know is science.”

At any rate, I learned—and you can learn this only by speaking to people who oppose your views—the tenacity with which believers cling to weak arguments, and their willingness to ignore scientific counterarguments. I also learned some people’s heavy reliance on empirical “evidence” for god as “that which lies beyond the present ken of science.” In other words, some believers do want empirical evidence for God. Of course I already knew all of this on some level already, but, as I say below, it’s another thing altogether to be accosted by a florid believer on the verge of yelling at me!

But I also learned more. Several people, including one gentleman who tried to completely monopolize the discussion, were clearly deeply offended by what I said, although I don’t think my talk was especially strident. This one fellow, who averred that he was a Christian, asked me if I had read the Bible. I think he was taken aback when I said “yes,” but he went on to say say that the story of Jesus in the Bible must have been true, because it reads as if it were true; and, after all, it must be true because five women reported seeing Jesus’s empty tomb, and that couldn’t be fiction because nobody would have believed women in that era. (You’ve probably heard this argument before, which I’ll call The Argument for God from Sexism). In addition, the gentleman said that thousands of people were reported to have seen Jesus after he was resurrected.

My response was that every scripture, including the Qur’an, seems real to its believers, and at any rate the accounts of Jesus’s resurrection and its sequelae are, as we know, conflicting among the Gospels. I mentioned that there is no extra-Biblical and independent evidence for the New Testament story, and yet there is for the Book of Mormon: an eyewitness statement at the beginning by eleven men who claimed they saw Joseph Smith’s golden plates. Why, I asked, was he not a Mormon or a Muslim? His response was simply, “I am a Christian.” That was a non-response and I’m afraid I got a little miffed at it, though I tried to be polite.

It was even worse because the man didn’t really have questions, but wanted simply to rant at me (the moderator didn’t stop it), and I didn’t have the presence of mind (I was trying to be polite) to simply cut him off. He continued to interrupt, not with questions but with statements, when I was trying to answer other people, and at that point I had to tell him to let those others have a chance to talk.

Needless to say, none of the vociferous Christians bought a book. (I have been accused of “preaching to the choir”, but I see that claim as unfair, for all books about nonbelief could be characterized the same way, and at any rate we know they are bought by people on the fence. Also, who buys books on religious studies except REAL members of the choir? I doubt that many nonbelievers buy books by Alvin Plantinga! If anybody’s books preach to the choir, it is those written by believers.)

But from all this I learned a lesson, which came to me when I was discussing this with a friend who has considerable experience dealing with petulant people. (That friend would be Dr. Alex Lickerman, the head of student health here at the University, a fantastic doctor, but also someone who has written, in his book The Undefeated Mind, about the psychological lessons to be drawn from dealing with distressed and troubled individuals–one every 20 minutes or so!)  Alex let me know that I simply must expect this kind of reaction when I make statements that pull the rug out from under people’s cherished beliefs. A talk like mine, which basically shows the intellectual vacuity of both regular belief and Sophisticated Theology™, is an attack not merely on irrationality, but on emotions that run deep, and on worldviews that have been held for a lifetime. The gentleman who responded with such ardor (and a few others who responded with clear but not as strong emotion), were, I think, motivated not by anger, but by fear—unconscious fear that they might be wrong.

My conclusion (which is really that of my confidante), is that I should not by any means dilute the strength of what I say, but that I should feel more empathy for people who oppose me, and perhaps start off any answer by saying that I understand where they’re coming from. I do feel that I am right in what I say, but I need to realize that, for many people, religion isn’t just a Sunday avocation, but something they’ve absorbed and made the core of their being. To a large part, it is their identity.

As I said, it’s one thing to absorb that lesson by reading about it, but it’s another to encounter that kind of fear and anger in person, and the latter lesson is much stronger. One thing I realize is that as I talk about the book, particularly in non-secular places, other people’s anger and fear will be activated, and I need to find ways to defuse it. I realize that I can’t dispel people’s belief in a one-hour lecture (though I can perhaps make fence-sitters question the validity of faith), but at least I can show them that I understand where they’re coming from. I have never been religious to that extent, so I will need to empathize with feelings that I’ve never felt, much less understood. That will be a good learning experience. And I will need to find ways to disarm people’s anger so that they can listen to what I have to say without their retreating to an obdurate defensiveness.

Further, I have to learn when a Q in the Q&A is nonproductive and overly long, and simply tell the person that we must move along because others have questions as well (as many did).

Most of all, I have to learn not to take this kind of opposition personally. Hitchens, of course, did quite well with strong opposition, because he simply didn’t care what others thought of him. Most people, including me, aren’t like Hitch. Although I will not allow ad hominem attacks on me, I need to absorb the idea that aggressive and sometimes offensive lines of questioning, and the refusal to listen to my answers, simply reflect on the background and religiosity of the questioner, and on the fact that I am undercutting a lifetime’s worth of unquestioned belief. As I’m a determinist, that lesson should be obvious.

This will not be easy for someone who’s never been a strong believer (I was mildly religious when younger), and who believes that the tenacity with which one holds one’s views should be proportional to the evidence supporting them. But it’s never bad to learn how to be more empathic toward one’s conspecifics!

My Five Books interview: recommendations for books dealing with the incompatibility of science and religion

May 22, 2015 • 8:18 am

When WEIT came out, I was interviewed by Sophie Roell of the “Five Books” section of The Browser.  Then was asked to choose five “popular” books about evolution that people could read if they wanted to learn about my branch of science. That interview (a transcription of a phone conversation, so the language is informal) is here.  It proved quite popular on the site, and I was pleased because Sophie is a terrific interviewer and asked good questions. (Unlike many interviewers, she actually read the books—all five of them—plus WEIT).

Now, six years on, Sophie interviewed me again on the occasion of the publication of FvF. This time I was asked to choose and discuss five books about the incompatibility of science and religion—books that could be useful to the average educated reader. I didn’t choose accommodationist books, for that wasn’t my brief.

This morning, our discussion, “Jerry Coyne on the incompatibility of religion and science was published on Five Books. I won’t list the books here, or reprise what I said about them, for you can read that at the site.

Although this is a done deal, if you think I omitted relevant books (remember, I was limited to five), do place a comment below. And remember, this is the transcription of a phone call, so it’s a conversation and not perfectly publishable prose. (Were I Steve Pinker, they’d be equivalent!)

 

Readers’ wildlife photographs

May 22, 2015 • 7:40 am

We have a grab-bag of miscellaneous photos today, starting with a “spot the animal” quiz. This one is easy, and an enlargement is at the bottom of this post.  Reader Florian wrote in yesterday:

Hiking in the desert this morning in the Indian Canyons south of Palm Springs, Calif. I stopped to take picture of the barrel cactus and then noticed the antelope ground squirrel [Ammospermophilius sp.] next to the cactus at [CLUE REDACTED] He seemed almost tame and let me get close for a nice cellphone picture as he was nomming a cactus fruit. This is a fairly remote trail and i was surprised he seemed accustomed to humans.

Can you spot the squirrel? You can enlarge the photo by clicking on it, then, after a short interval, clicking again to see it on its own:

Diana MacPherson was suffering from a migraine yesterday, and was consoled by finding a nest of baby bunnies:

A bunny has a nest under a mulberry tree in my yard. My dog disturbed them this morning so they needed to be put back in their nest. Here are a couple of iPhone pictures. They are so cute that I wish I could keep them! I love their little feet!

JAC: I suspect these are eastern cottontails (Sylvilagus floridanus), but I don’t know from rabbits and so may be wrong. I didn’t know that wild rabbits could have white streaks on their heads.

Apparently Stephen Barnard, looking at his Idaho digs on Google Earth, spotted his border collie Deets in the photo. Here’s the screenshot with the email:

He’s the black and white dot behind the Subaru, right in the center. Sorry, but this strikes me as funny.

Stephen also sent this classy photos of squirrels, but I’ve lost the species name.

Reader Jonathan Wallace sent a photo clearly showing birds’ concept of personal space.

This picture is of Black-Legged Kittiwakes, Rissa tridactyla, nesting on a former flour warehouse (now a modern art gallery) in Gateshead, England.  Kittiwakes normally nest on sea-cliffs and there are substantial populations around the British coast but they have proved to be quite amenable to using buildings in coastal town as artificial cliffs.  The colony in Newcastle-Gateshead is interesting in being over 8 miles up-river from the sea and is claimed to be the furthest inland in the world.  There is a webcam on the art gallery birds at this site.

The “most embarrassing moment” contest winner

May 22, 2015 • 6:30 am

When Leo Glenn won the contest with his story about having to bathe nude in a Japanese hot spring with his nether parts dyed bright red from his bathing trunks, he wrote this response (I asked him what kind of cat he’d like drawn in it):

What a thrill to win the contest! Thank you so much for holding it. It was great fun both to enter and to read all of the other entries. Of course, I had already pre-ordered your book, which works out great. Now I will have a loaner and not have to fret about losing the signed copy. This will be our second autographed book of yours. We are proud owners of an autographed copy of WEIT, with a drawing of our cat Baxter, a former World Cat Day honoree on your website. (He was the cat found by the side of the road with a glass jar stuck on his head.) [JAC: see here for story and photo of Baxter]

It seems only fitting this time to honor our cat Gremlin, who turned 18 this past March. She was the runt of a litter of six kittens born to a stray we had temporarily taken in so she could give birth  in our apartment. We were living in Los Angeles at the time and planning to move back to PA to attend grad school, so our goal was to find homes for the mom and kittens before we embarked on our cross-country road trip. Needless to say, being the inveterate softies that we are, my wife and I ended up with two of the kittens, who traveled with us, camping in Yellowstone and other places along the way, and even attending a primitive living skills course in Montana. They ended up being great travelers, except for the first day, which Gremlin spent sitting on my shoulder and screaming in my ear while I drove–nonstop for eight hours.

Gremlin was just a temporary nickname, because she was the smallest of the litter but had, at the time, unusually large ears. She was the first to open an eye, and she would put her head above the box and stare out at the wide world with one eye and those huge ears. We thought she looked like a gremlin from the movie. Of course, the name stuck. We lost her sister to cancer four years ago, and we thought we were going to lose Gremlin this year, but thanks to our vet and some thyroid medication, she looks as if she may pull through. She is very dear to us. Losing her will be very, very hard. Long story, sorry, but I know you like to have back story on the moggies.

I drew Gremlin, which was hard because she’s a calico and I had to find orange paint, and sent the book. It arrived yesterday, and I had to show the pixture of Baxter (who is still doing fine) and the book, along with a further note from Leo:
Just wanted to let you know that the book arrived yesterday. Thank you so much. Here is a photo of Gremlin (reluctantly) posing with her lovely portrait, although I’m not sure she fully appreciated it. I had already received the Kindle version of your book and have been reading it and enjoying it immensely.

Friday: Hili dialogue

May 22, 2015 • 4:58 am

It’s been a long and very enervating week, and Professor Ceiling Cat is looking forward to a rest this weekend. I have a reddit “ask me anything” today at noon, and that should be fun. Then. . . rest. Meanwhile in Dobrzyn, the Princess, like Ariana Grande,is once again demanding, that she be carried about. Here she is wailing on the windowsill for a hand-carry into the house. What a spoiled moggie!

A: Do I have to carry you inside, again?
Hili: So much ado about nothing.

In Polish:
Ja: Znowu cię trzeba do domu nosić?
Hili: Tyle hałasu o nic.

 

 

Pupa in Trinidad mimics snake (and moves!)

May 21, 2015 • 12:15 pm

This piece, from nerdist. com, describes one of the more amazing cases of mimicry I’ve seen. Look at the picture below, and see what you think it is:

CatSnake_FEAT-970x545

It’s not a snake, despite the very snake-y appearance of the thing. It has eyes (fake), the eyes even have a “glint” in them (fake), it has a fake mouth, and even fake “scales”.

It’s from Trinidad, and it’s one of the life stages of a lepidopteran. In fact, it’s the pupal case of the Daring-Owl butterfly Dynastor darius darius, a subspecies from Trinidad (the species D. darius is found in Central and South America).

Here’s a picture of an adult of another subspecies, D. darius stygianus:

Dynastor_darius_062705_COSTA_RICA_HEREDIA_PROV._La_Selva_Biological_Station_Sarapiqui_27-VI-2005_Yahaira_Rojas_Duran_3And the caterpillar of D. darius darius, which is weird looking but not nearly as weird as the pupa:

CatSnake_Pillar-615x460

It’s when this caterpillar becomes a pupa that it turns into a snake mimic, and the mimicry, as you can see above, is amazing. Here are a few more photos:

CatSnake_3

CatSnake_2

This is what the predator would see. Look at those eyes!

CatSnake_1

Now remember that the pupa is stuck in one place, which raises the question of why it mimics a snake. After all, a potential predator (likely a bird) inspecting the pupa might discover that it can’t move, and then nom it. But, as the article notes, the selective advantage of mimicking a snake doesn’t require movement or the ability to escape a predator once you’ve been spotted. The predator, seeing what looks like a snake, could simply flee without closer inspection.

But there’s more, for the pupa apparently can move—violently—when disturbed. A 1978 paper in Psyche by Annette Aiello and Bob Silberglied reports this in a few tantalizing words:

Screen Shot 2015-05-21 at 8.33.36 AM

I’d really like more information on how a pupa can “wave violently back and forth”, how it detects the predator, and what the movement is like. I believe the authors’ claim, for I knew both of them at Harvard, and they were scrupulous researchers (tragically, Bob was one of the victims of the 1980 crash of an Air Florida plane in Washington, D. C.). A mimetic and moving pupa like this is a remarkable product of natural selection.
There’s one more issue: the nerdist article notes this:
For 13 days, D. darius destroys and reforms itself inside what looks like the head of a Gaboon pit viper (though the snakes aren’t native to Trinidad).
And indeed, it does look like a Gaboon pit viper (Bitis gabonica):
gaboon-viper-2009-9-10-19-41-38
The problem is that this snake is found only in west central Africa, and it’s unlikely that the pupa, found in the Americas, is mimicking it. For such mimicy to work, a potential predator must have had some kind of experience (either direct or through genes inherited from its ancestors) with the viper, which can’t be true in this case. The prediction, then, is that there must be some venomous snake in the range of D. darius that looks like the pupa, endowing a selective advantage to mimicry.  I’m not a herpetologist, but I know some of you out there will be able to pinpoint the potential “model.”
