My TAM interview, part 3

January 7, 2014 • 11:01 am

Here’s the last bit of the three-part interview I did at the July TAM with Joel Guttormson, Outreach and Event Coordinator for the Richard Dawkins Foundation for Reason and Science.

By the way, since I’ve read Addy Pross’s short book What is Life? How Chemistry Becomes Biology, I’ve realized that abiogenesis (the origin of life from nonlife) and the subsequent evolution of life are really not separate issues, for abiogenesis surely involved the same kind of competition between replicating systems that characterizes things we’re comfortable calling “alive.”

Christmas trees are like catnip to Linton lions

January 7, 2014 • 8:12 am

I haven’t the slightest idea where Linton is in England, but I’ve posted a fair number of items from the Linton Zoo. (I’m sure readers will enlighten me.) Here, thanks to the feline-finding tenacity of Matthew Cobb, is a video of the lions at Linton going nuts when they get some recycled Christmas trees:

The BBC News describes the fun:

A pair of African lions have gone wild for Christmas trees after a Cambridgeshire zoo appealed for people to donate them for recycling.

The trees are being reused by Linton Zoological Gardens as big cat toys, bio-fuel and, if they still have roots, to enrich the zoo’s enclosures.

Manager Dawny Greenwood said the scented trees are “almost like catnip” for the resident big cats.

She added: “They just love the trees, it gives them hours of fun.”

Catnip, sometimes known at catmint, is a plant of the mint family and can cause many cats euphoria.

The zoo’s tigers and snow leopards also play with the trees, those that are “beyond their best” are used for the zoo’s bio-burner.

“This provides additional heating and hot water to help run our zoo at this very expensive, cold time of year,” said Ms Greenwood.

It’s a shame, though, that these magnificent beasts, evolved to roam free, are reduced to rubbing against Christmas trees. If I had my way, zoos wouldn’t be allowed to have beasts like these unless they were severely endangered.

If you live near Linton, take your tree there and help keep the lions from being bored.

Douthat responds to me, decries materialism again

January 7, 2014 • 5:45 am

At his own New York Times “opinion blog”, Ross Douthat has responded to my New Republic column (based on a piece I wrote here) criticizing his own “Christmas column.” You may remember that dreadful piece in which Douthat dissed secularism as a “rope bridge flung across a chasm” that “wafts into a logical abyss.”

He also claimedthat there were serious cracks in materialism—cracks apparently illustrated by philosopher Tom Nagel’s unevidenced evocation of a teleological force in biology, as well as by Steve Weinberg’s correct claim that we don’t yet understand everything about physics.  That was Douthat’s sole evidence that the materialist paradigm is about to disintegrate.

Doubthat’s “Christmas” column was a desperate defense against the inroads of secular reason against his beloved Catholicism, but New York Times readers weren’t fooled (see the “reader’s choice” comments at the end of his column: they’re nearly all critical and anti-religious).

In his new piece, “The confidence of Jerry Coyne,” Douthat continues his cluelessness by trying to show that my materialism is inconsistent in two respects and overconfident in another. His arguments:

1.  If I think the “self” is an illusion, I have no justification for saying that I have a “purpose.” 

Douthat:

So Coyne’s vision for humanity here is heroic, promethean, quasi-existentialist: Precisely because the cosmos has no architect or plan or underlying purpose, we are free to “forge” our own purposes, to “make” meaning for ourselves, to create an ethics worthy of a free species, to seize responsibility for our own lives and codes and goals rather than punting the issue to some imaginary skygod. (Ayn Rand could not have put it better.) And these self-created purposes have the great advantage of being really, truly real, whereas the purposes suggested by religion are by definition “illusory.”

Well and good.  But then halfway through this peroration, we have as an aside the confession that yes, okay, it’s quite possible given materialist premises that “our sense of self is a neuronal illusion.” At which point the entire edifice suddenly looks terribly wobbly — because who, exactly, is doing all of this forging and shaping and purpose-creating if Jerry Coyne, as I understand him (and I assume he understands himself) quite possibly does not actually exist at all? The theme of his argument is the crucial importance of human agency under eliminative materialism, but if under materialist premises the actual agent is quite possibly a fiction, then who exactly is this I who “reads” and “learns” and “teaches,” and why in the universe’s name should my illusory self believe Coyne’s bold proclamation that his illusory self’s purposes are somehow “real” and worthy of devotion and pursuit?

Douthat sees this as a “contradiction.”  Apparently his notion of “purpose” involves something given by Almighty God, and therefore whatever motivates the collation of atheistic neurons that feels itself to be Jerry Coyne cannot have a “purpose.” But of course Jerry Coyne does exist as an identifiable physical entity that feels itself to be an agent. That agency is an illusion: there is no little person in my brain that directs the activity of my neurons. There is no Coyne “soul” separate from those neurons, and neither is there a Douthat “soul.” But there still is a human being that bears my name and has desires and feelings different from those of other beings. These are certainly as “real” as any other feeling. And why should we believe Douthat’s bold proclamation that his body harbors a soul given by God, and that his God-given purpose is “real”? Perhaps Douthat should first give us evidence for his God before we take his purpose as more real than mine.

Further, as I and others maintain, our sense of agency is a remarkable illusion confected by evolution through the arrangement of our neurons. It may well have been a feature that was evolutionarily advantageous, and installed by natural selection. And that evolved collection of neurons, with its sense of agency, takes pleasure in certain things and feels it has goals.  That those feelings and goals are an inexorable result of our genes and environments is discomfiting to some, but that’s where the evidence points.  And while those goals are more complicated than those of, say, a squirrel, whose “purpose” is to reproduce, gather nuts, and bask in the sun, they all come down to whatever motivates an evolved organism—from the simple goals of simple organisms to the complex goals of complex organisms with complex brains.

Douthat doesn’t like this because he wants there to be a Douthat Soul that has a “purpose” bestowed by a celestial deity.  But there’s simply no evidence for that.  He wants there to be more than materialism, but there’s no evidence for that, either. We have no need of such hypotheses, except as childish desires for a father figure and an afterlife. Imagine a Martian zoologist observing a Catholic mass for the first time and trying to understand it. I suspect it would come off as some kind of adult game.

2. If we are evolved beings, then there is no justification for being moral.

Coyne proposes three arguments in favor of a cosmopolitan altruism, two of which are circular: Making a “harmonious society” and helping “those in need” are reasons for altruism that presuppose a certain view of the moral law, in which charity and harmony are considered worthwhile and important goals. (If my question is, “what’s the justification for your rights-based egalitarianism?” saying “because it’s egalitarian!” is not much of an answer.)

The third at least seems to have some kind of Darwinian-ish, quasi-scientific logic, but among other difficulties it’s an argument that only holds so long as the altruistic choice comes at a relatively low cost: If you’re a white Southerner debating whether to speak out against a lynching party or a Dutch family contemplating whether to hide your Jewish neighbors from the SS, the respect factor isn’t really in play — as, indeed, it rarely is in any moral dilemma worthy of the name. (And of course, depending on your ideas about harmony and stability, Coyne’s “harmonious society” argument might also seem like a case against opposing Jim Crow or anti-Semitism — because why rock the boat on behalf of a persecuted minority when stability and order are the greater goods?)

The first two arguments are not at all circular, but the results of reasoning and evolution.  I’ve often said that I don’t know how much of human morality comes from natural selection’s instilling in us certain behaviors and feelings, and how much is due to reason. But I am virtually certain that none of it is due to God.

I want to live in a society where people are treated fairly and in which, if I were disadvantaged, people would try to help me. For it is only an accident of history that has made me more advantaged than others. Acting altruistically is what I consider “moral,” though I’d prefer to use the term “good for society as a whole.” Yes, that is a form of consequentialism, but in the end one has to decide “oughts,” and it’s always a judgment call.

But it’s better to make a judgment call based on science, observation, and reason than on the dictates of a fictional being. We are evolved social beings that have been bequeathed big brains by natural selection, and can reason about what kind of society we want. The answer about why we should be altruistic or compassionate is not “because it’s egalitarian,” but because it’s better for all of us if we increase well-being. (I don’t think that’s all there is to “morality”, but to a large extent I see Sam Harris as right. Although morality is not objective, it almost always comports with “do what increases well being.”) And, at any rate, answering “Why be altruistic?” with “Because God wants us to be” is hardly more satisfying.

As for “stability and order” being the greatest goods, we now realize that if one buys such stability at the cost of disenfranchising groups of people for no discernible reason, that creates a society in which the disorder remains, but is hidden and suppressed. The stability and order are illusory, for there is instability and disorder in people’s minds, and the general well-being could be greater.  Finally, not all evolved “moral intuition” is useful in today’s world, for we no longer live in the small social groups that dominated 99% of our evolutionary history. Xenophobia, for instance, may be one such vestigial behavior.

3. I’m too confident about the ultimate victory of secular reason.

Douthat:

Finally, I enjoyed Coyne’s parting sally:

“Douthat is wrong. The cracks are not in the edifice of secularism, but in the temples of faith. As he should know if he reads his own newspaper, secularism is not cracking up but growing in the U.S. He and his fellow religionists are on the way out, and his columns are his swan song. It may take years, but one fine day our grandchildren will look back on people like Douthat, shake their heads, and wonder why some people couldn’t put away their childish things.”

For a man who believes in “a physical and purposeless universe” with no room for teleology, Coyne seems remarkably confident about what direction human history is going in, and where it will end up. For my part, I don’t make any pretense to know what ideas will be au courant a hundred years from now, and as I said in the column, I think there are all kinds of worldviews that could gain ground — at the expense of my own Catholicism and secular materialism alike. (Right now, the territory around pantheism and panpsychism seems ripe for further population, but that’s just a guess.) But I suppose it’s a testament to my own childish faith in the “neuronal illusion” that is the human intellect that I can’t imagine a permanent intellectual victory for a worldview as ill-served by its popularizers as atheism is by Jerry Coyne.

Well, the fate of secularism hardly depends on my efficacy as a small-time writer! Of course Douthat doesn’t really conceive of his faith as childish, but if that’s the case, and he’s a public intellectual, let us hear the reasons for his belief, and why he’s so sure that Catholicism is the “right” belief rather than Islam. For, if he’s made a mistake in that case, he’ll burn in hell forever.

All I know is what I see and what I discern from history, and in this I’ve been influenced by Steve Pinker’s book The Better Angels of Our Nature.  There does seem to be a pattern in human behavior that, while not completely smooth, is moving towards an appreciation for the sufferings of others, whether those others be women, gays, minorities, children, or animals. And religion is clearly on the wane. It was unthinkable to not be a Christian in Europe three centuries ago, but now in many parts of Europe belief in God is a minority view. It is now unthinkable that, at least in Western countries, child labor, public torture of animals as public amusement, and slavery will ever return.  (Yes, bullfighting and fox-hunting are on the way out). Or that Douthat’s Catholic church could put heretics to the stake. Or does he think that an Inquisition is just as likely as the demise of Catholicism?

Of course it will take centuries to dispel the illusion of the supernatural, but in the end I think the lack of evidence will triumph over wish-thinking. I am not 100%, but the evidence is more on my side than Douthat’s. “Pantheism” in many cases is just another word for “atheism,” and panpsychism—the view that mind permeates the universe—seems silly, even if it’s touted by Thomas Nagel. 

In the end, Douthat, like many, is simply uncomfortable with a materialist worldview, and wants desperately for there to be More Than That. He yearns for a teleological or divine force that, he thinks, will give our lives real purpose and meaning, and serve as a ground for morality. The lack of evidence for such a force must surely disturb him a bit. If it doesn’t, he’s not thinking.

Conjoined whale calves found dead

January 7, 2014 • 1:57 am

by Matthew Cobb

Some rather sad pictures posted yesterday of a pair conjoined grey whale calves, found dead in a lagoon in Baja California. Grey whales give birth around this time of year. There’s a rather gruesome video, too. Grindtv.com has this:

Unfortunately, the twins discovered in Scammon’s Lagoon did not survive and most likely were miscarried. The the carcass is only about seven feet long, versus the normal 12 to 16 feet for newborn gray whales.

Alisa Schulman-Janiger, an American Cetacean Society researcher, pointed out that the twins were severely underdeveloped and wondered whether the birth or stillbirth might also have killed the mother.

More about the Pew poll on evolution acceptance

January 7, 2014 • 1:30 am

NOTE BY JAC:  I still am baffled by the Pew’s finding that Republicans seem to have become more creationist between 2009 and 2013, for the Gallup Poll shows the 20% disparity already in 2008.  In that poll, the percentage of young-earth creationists was 60% among Republicans, 38% among Democrats, and 40% among Independents. The gap that Pew says is widening, then, appears in the Gallup data to have been that wide already five years ago.  Since the issue is the same, human evolution, I can only attribute it to different sampling techniques or, as Greg suggests below, to the order in which questions were asked.

______

by Greg Mayer

I’ve already posted twice on the Pew poll on evolution acceptance, first to bring it to WEIT readers’ attention while noting the disparity between the Pew poll and Gallup’s results on the same issue, and then to note an erroneous criticism of the poll by Dan Kahan. I’d like to note three further developments.

The most interesting is a further report from Pew written by Cary Funk (if you look at nothing else mentioned here, look at this report), I’ll mention two other items first.

First, Charles Blow at the New York Times, in a piece entitled  “Indoctrinating Religious Warriors“, considers what the poll says about the political and religious landscape of America. He’s saddened by the fact that more Republicans now accept creationism than evolution:

In fact, this isn’t only sad; it’s embarrassing.

I don’t personally have a problem with religious faith, even in the extreme, as long as it doesn’t supersede science and it’s not used to impose outdated mores on others.

But as Blow well knows, the only religious extremists that make the news are precisely the ones who want their faith to supercede science and to impose their mores on the rest of society. He attributes its recrudescence to the strategy of the Republican party:

But I believe that something else is also at play here, something more cynical. I believe this is a natural result of a long-running ploy by Republican party leaders to play on the most base convictions of conservative voters in order to solidify their support. Convince people that they’re fighting a religious war for religious freedom, a war in which passion and devotion are one’s weapons against doubt and confusion, and you make loyal soldiers.

There has been anti-science propagandizing running unchecked on the right for years, from anti-gay-equality misinformation to climate change denials.

Second, Andrew Sullivan, in “Converting to Belief in Evolution“, has looked at the poll again, and points to Karl Giberson (whom Jerry also commented on) asking whether evangelical Christianity’s antagonism to science will push young people away from evangelical Christianity. Giberson found this prospect “alarming”, but evidently Andrew doesn’t. (As a gay Catholic who accepts at least theistic evolution, Andrew has longstanding political and theological differences with evangelicalism.)

Finally, Dan Kahan has accepted that his chief argument against the Pew poll—that its reported numbers must be incorrect—is wrong. He did so in response to a commenter on his site, who provided a hypothetical numerical example refuting Kahan’s assertion. I showed that Kahan was in error with a general argument about the statistics of sums, but a concrete counterexample is also a satisfying form of refutation. But most importantly, Pew, without mentioning Kahan, has released a detailed answer to the question that Kahan thought indicated numerical hanky-panky: “If the views of the overall public have remained steady, and there has been little change among people of other political affiliations, how does one account for the Republican numbers? Shouldn’t the marked drop in Republican believers cause a decline in the 60% of all adults who say humans have evolved over time?” The answer is of course ‘not necessarily, and, in fact, not in this case’.

Kudos to Kahan for accepting the invalidity of his mathematical argument, but, oddly, he continues unchanged in his animus toward the Pew poll and one of its striking findings (see the updates and a further post here). As I said, his reactions to the poll seem to be “merely expressions of his own prejudices”, and not terribly dependent on the actual poll results, since he continues to hold them although though his conclusions on the poll have been shown to be in error. The whole sequence of what he writes about the poll is a wonderful example of the type of reasoning which, in another context, Sam Wang of Princeton has called “motivated reasoning“.

The new Pew report (which, as I said, is the thing really worth looking at here), clearly answers Kahan’s doubts. Here’s their table nicely illustrating, neither generally nor hypothetically, that there’s nothing wrong with their numbers (note that the last column shows, as stated in my first post, that the overall result is a weighted sum that includes all political response classes):

Pew 2nd evolution 2013-1

But what was the cause of the shift in Republican opinion? It’s not obviously due to changes in the demographic, religious, or ideological profiles of the Republican party, as they changed little between the two surveys:

Pew 2nd evolution 2013-2

Pew 2nd evolution 2013-3 To my mind, the most interesting new nugget in this report is that the biggest shift of Republicans toward creationism has occurred among the least religious Republicans. From the report:

In fact, however, the surveys suggest that the change in views on evolution occurred especially among the less religious segments of the GOP. Among Republicans who attend worship services monthly or less often, the share who say humans have evolved over time is down 14 percentage points, from 71% in 2009 to 57% today. Among Republicans who attend services at least weekly the share who believe in evolution has gone from 36% in 2009 to 31% today, a difference that is not statistically significant.

This may support the suggestion of, among others, Zack Beauchamp and Paul Krugman that accepting creationism has become part of Republicans’ “team” or “tribal” identity: very religious Republicans were already mostly creationist for religious reasons, and now less religious Republicans are following for reasons of party solidarity. (Oddly, Kahan, who called Krugman’s response to the poll “absurd” and “devoid of reflection”, seems to agree with this as well.)

The new Pew report also considers the possibility of wording issues affecting the response. In this case, it was not the wording of the questions on evolution (which were unchanged), but the words of the preceding questions. The 2009 survey was full of questions on science, which may have “primed” respondents to give more ‘scientific’ answers, while in the 2013 survey the evolution questions were preceded by religious questions. I would not be surprised if such differences have an effect; such wording effects may account for some of the disparities between Pew and Gallup results on the same issues.

Now that’s cold!

January 6, 2014 • 11:59 pm

How cold was it in Chicago yesterday? With the wind chill, it was  -40, which happens to be the one temperature at which Farenheit and Celsius measures coincide.

It was so cold, in fact, that they had to bring the polar bears inside at the Lincoln Park Zoo. As Rebecca Boyle notes on Eek Squad:

“In Chicago we’re accustomed to weather extremes, with very cold winters and very hot summers, so the animals that are part of our zoo are chosen for their hardiness for winter or summer,” [public relations director Sharon] Dewar says. “But this is obviously an excessive extreme. So even animals that are pretty hardy, and would be able to stay outside for normal winters — like the Mongolian camels and polar bear — even those animals we’re keeping indoors.”

I’ll just repeat that: It’s so cold in Chicago, the polar bear is inside.

Thank Ceiling Cat that it’s been balmy in Poland. I got out at just the right time.
