Fall: University of Chicago

November 1, 2013 • 5:07 am

October has gone again, has gone again, and in Virginia the chinkapins are falling.

But in Chicago the leaves are turning; not as good a show as last year, but we have some nice bits. Here are four photos I took yesterday right outside my office, on the way to where I get lunch noms. The student union (“Reynolds Club”) is the building to the left (click all photos to enlarge):

And the red tree to the right in the photos above. Can anyone identify it? (I can’t.)

O Mio Babbino Caro, at age 9

October 31, 2013 • 5:56 pm

I’m sure, like the last time I presented an young opera-singing prodigy, people will carp about her singing, but really, Amira Willighagen is only nine. This is apparently from the show “Holland’s Got Talent,” and it seems to.

Plus it’s my favorite of all opera arias, and a perennial crowd pleaser.  But listen before you carp. (My only plaint: she goes high on the last note.)

I have to note that I can sing this in the original Italian—but not on key!

O mio babbino caro,
mi piace, è bello bello,
vo’andare in Porta Rossa
a comperar l’anello!
Si, si, ci voglio andare!
E se l’amassi indarno,
andrei sul Ponte Vecchio
ma per buttarmi in Arno!
Mi struggo e mi tormento,
O Dio! Vorrei morir!
Babbo, pietà, pietà!
Babbo, pietà, pietà!

 

Happy Halloween!

October 31, 2013 • 2:06 pm

During my whole adult life, I’ve wished I could go out in costume every Halloween and get candy, but that’s no longer possible: I’m too old. (When I was a kid we’d always go to the rich people’s neighborhoods, as they’d give out whole candy bars instead of stupid Mary Janes or candy corn).  I suppose I could just buy candy now, but it’s not the same, and I don’t have kids to tote around as bait.

Regardless, here’s wishing you have a sucrose- and felid-filled holiday, and that you stay away from that flavored petroleum byproduct called “candy corn”! (Also avoid the cylindrical red byproducts called “Twizzlers”.)

And here are some photos:

Reader Stephen Q. Muth took a holiday-themed picture, adding some information (note the Satanic pumpkin):

Here is my neighbor’s kitteh, appropriately named ‘October’, posing in the garden with an example of the recent harvest.  A self-described atheist and avid singer/vocalist, October’s favorite activities are control of garden pests, endless requests for walksies, and the occasional consumption of neighborhood children. October adopted my neighbor on 9/11/2001, and despite his fearsome appearance here, is really a big sweet softie.

Reader P. sent a video of big cats playing with pumpkins:

Here’s a Halloween kitteh envisioned as the Bride of Frankenstein:

Tanya Luhrmann jumps the shark of religion

October 31, 2013 • 10:16 am

UPDATE: Over at The New Republic, Isaac Chotiner also takes out after today’s Luhrmann piece. He also excoriates her for her last paragraph:

No one is saying that spirituality can be made to “go away,” and whether it does has nothing to do with whether ghosts actually exist. But for people like Luhrmann, the whole point is to muddy these waters. She concludes:

But what this research makes clear is that when people report that they hear their dead husband or are terrified by an evil presence that groped at their throat in the night, they are not necessarily making it up, nor are they crazy. Events like these are rather what Ann Taves, professor of religious studies at the University of California, Santa Barbara, calls the “building blocks” of religious experience. The experiences are psychologically real events. How you interpret them is up to you.

It’s all up to you! Well, of course it is up to you, since we have this thing called freedom of religion and don’t live in a totalitarian society. We can thank Luhrmann for reminding us of this. In the meantime, she might decide that if she wants to be an opinion columnist, she should offer her opinion. My hunch is that the reason she doesn’t want to do so is that it might lead to the following conclusion: Not all “interpretations” are equally valid.

____________

One of the worst (and most puzzling) things the New York Times has done is give Tanya Luhrmann a regular column.  She does nothing but osculate the rump of faith, and all I can imagine is that the Times has decided it needs someone with street cred (Luhrmann is an anthropology professor at Stanford) to make nice to religion. The Times is really, really soft on faith.

In her op-ed piece in today’s Times, “In the presence of all souls,” Luhrmann has finally showed her hand: her work is not simply about objectively reporting the doings of religious people, but about justifying their beliefs.  She has lost any shred of objectivity she claimed to have.

Lurhmann was apparently inspired by the death of her dog, as after that demise she still occasionally felt her dog’s presence. (That also happened to me with my late cat.) Doing a bit of digging, she found that people often feel the presence of dead friends or loved ones. In fact, 80% of people have such experiences, which Luhrmann calls “real sensory events.” That wording is an ambiguity that fuels this piece: the blurring between reality and psychological illusions.

She then takes up “sleep paralysis,” a phenomenon whereby people seem to be awake in bed but can’t move. This is often accompanied by strange hallucinations like the presence of ghosts or demons. Luhrmann argues that many allegations of witchcraft throughout history could be based on this form of temporarily paralysis. Unfortunately, I don’t know much about its physiological causes, and Luhrmann doesn’t describe them.

What she does do is argue that just because we experience such hallucinatory phenomena doesn’t mean that the spirits of the dead, or of evil, aren’t real.  In other words, she’s using hallucinations to argue that the truth claims of religion could be real, an argument that simply doesn’t make sense. But if you think I’m making this up, just read her words:

To be sure, the fact that we can identify in-the-body phenomena (hallucinations, sleep paralysis) associated with ideas about the supernatural does not necessarily mean that those ideas are false. Mr. Hufford, who also studies near-death and other remarkable experiences, is very clear about that: “Learning as much as we can about spiritual experience does not make spirituality go away.”

But what this research makes clear is that when people report that they hear their dead husband or are terrified by an evil presence that groped at their throat in the night, they are not necessarily making it up, nor are they crazy. Events like these are rather what Ann Taves, professor of religious studies at the University of California, Santa Barbara, calls the “building blocks” of religious experience. The experiences are psychologically real events. How you interpret them is up to you.

Can you imagine?  We identify delusions or illusions, and can probably show their physiological, neurological, and psychological causes. The ghosts and dog spirits aren’t real, and none of those returning spirits has yet imparted to us any credible information about the afterlife. We can mimic such experiences with various drugs or brain stimulation. Yet Lurhmann nevertheless concludes that there still might be something to spirituality: the presence of real ghosts, souls, and spirits. The fact that there is absolutely nothing to support their existence doesn’t deter her one bit. If they existed, there should be evidence for them, but there isn’t. Conclusion: we can provisionally abandon those beliefs until we get real evidence.

Instead, Luhrmann chooses the opposite, unparsimonious conclusion. She avers that the experiences are “psychologically real” and “open to interpretation.”  That’s like saying that there are many people who are convinced that aliens are communicating with them, or that they’ve been abducted by UFOs.  Will she then argue that these experiences are also “psychologically real”, and “how we interpret them is up to us.” If you take LSD you’ll have all kinds of “spiritual” hallucinations. Will she then claim that those, too, are grounds for spirituality, and that maybe, just maybe, they give credibility to what we experienced?

No, Dr. Luhrmann, reality is not a judgment call on a delusion. It’s something that can be investigated empirically and cross-checked with other researchers. Determining whether those experiences say something about reality is not up to the average person; it’s up to science.  She fails to understand (or willfully promotes the confusion) that psychological reality is not always real reality. And the worst instance of that—the one that earns Luhrmann her grants, papers, and money—is religion.

The last sentence of her piece infuriates me. It’s a total cop-out, an abandonment of science, and a sop to believers, reassuring them they may be neither delusional nor crazy about God. As one of my friends said after reading this, “She’s slipped completely off the deep end. They might as well have Deepak Chopra as a columnist.”

Templeton, and the New York Times, has paid Luhrmann good money to write this kind of nonsense. Why they do it is beyond me.

Halloween Google doodle

October 31, 2013 • 9:17 am

Today’s Google Doodle (screenshot below; go to link to see it) allows you to mix a witch’s brew.

As c|Net reports:

Users can combine various ingredients to play mini games, from whack-a-mole with the undead, to a shell game where your goal is to find a mummy in a coffin. There are several others, which can be found with experimentation.

That’s about all you can do with this one, so if you’re looking for an ending, it’s a bit of a cliff-hanger.

I haven’t tried it (work calls), but if you’re indolent and ready to play, report back.

Ceci n’est pas une fourmi

Nope, not an ant, but a spider.

This photo of an ant-mimicking spider came to me from Chris Buddle via Geekinquestion via Matthew Cobb. I don’t know the species, but the mimicry is remarkable: the front legs are held out in front so they resemble the antennae of an ant (spiders have 8 legs, ants 6), and the cephalothorax (the fused head and thoracic sections of a spider) has a fake constriction so it looks like the true tripartite nature of an ant (separate head, thorax, and abdomen).

Picture 7

There are many selective pressures that could modify a spider’s morphology like this, including fooling the ants so they accept the spider as one of their own, allowing it protection from predators as it hides among ants (birds often avoid eating ants). Such mimicry could allow the spider to travel with the ants and get access to food, as in the case of spiders that evolve to resemble army ants.  It could also allow the spider to fool the ants so it can actually eat them.

I don’t know the answer here (and of course multiple selection pressures could be operating), but it is remarkable how the spider’s environment has interacted with its genes to cause such a resemblance.  It also shows that whatever genetic constraints were operating in the spider, they weren’t sufficient to prevent a complete re-molding of its body.

It was Darwin’s genius to use the success of artificial selection—plant and animal breeding—as a way to convince people that natural selection could also produce such changes. That is why he starts off The Origin with a discussion of breeding in pigeons and other species. As he said, “Breeders habitually speak of an animal’s organisation as something quite plastic, which they can model almost as they please.” From there it’s not much of a stretch to see how nature (and I’m speaking shorthand here, for “nature” is not a force that operates on genes), could also do such modeling.
