Ought From Naught

In a post over at VFR, Lawrence Auster comments on an essay by Stanley Fish in which Professor Fish remarks on the inability of pure “secular” reason, bereft of normative bedrock in the Divine, to provide any “oughts”. This is catnip to Mr. Auster, who is, despite having various admirable qualities, a crusading anti-Darwinist.
The argument [...]

Stupid Cephalopod Tricks

Making the rounds today is some marvelously entertaining footage that some biologists think is evidence of tool use amongst invertebrates. I think it’s safe to say you’ve never seen this before; see for yourself here.

Is Secularism Maladaptive?

In the paper the other day there was an item about Pope Benedict’s recent remarks to the people of the Czech Republic. The Pope, speaking to one of the most secular societies on Earth, sought earnestly to persuade them of the dangers of a society without God.
On a superficial level this is easy enough to [...]

Peeing And Becoming

There was an amusing anecdote in my family about my long-departed Scottish grandmother, who, in the course of helping to potty-train one of her grandchildren (indeed I think it might have been yours truly), attempted to stimulate the “wee bairn” by running the water in the sink. The plan, however, immediately backfired, and she ended [...]

Parallel Postulates

Lawrence Auster is a very smart fellow, and I admire his formidable presence on the ramparts of Western culture. But he has curious blind spots, for one so intelligent, and one of them has to do with Darwinism.
Have a look at this exchange with a reader, one who patiently tries to explain, as I have [...]

Tower Of Babel

In grappling with persistent questions regarding key aspects of human existence and the natural world — intentionality, free will, morality, and so on — it is very easy to become entangled in terminological difficulties. Here’s a particularly contentious example.

Nothing To See Here

We are still on vacation, but I did find some time for the blogosphere this evening. I spent it, though, reading and commenting on a fascinating thread about free will over at Bill Vallicella’s place.

Pensée

From number 720, in the Krailsheimer edition:
Ethics and language are particular, but also universal, branches of knowledge.
In this illuminating insight the great Pascal anticipates moral philosophers and evolutionary biologists such as John Rawls and Marc Hauser by over 300 years. As homo sapiens we all share an innate moral faculty and finite ethical grammar, just [...]

The Gift That Keeps On Giving

Diligently doing its part to undermine America’s intellectual respectability and competitiveness, the Texas Board of Education is taking up an amendment this week that seeks to smuggle religious myths, such as the transparent Creationist fraud known as “Intelligent Design”, into the science classroom in the name of “academic freedom”. Were this dispute taking place only [...]

Endangered Species

In today’s email, a friend has sent me some photographs of angry Muslims demonstrating on the street in what appears to be London. They are carrying signs, glowering menacingly, brandishing their fists, and shouting. The messages they carry are clear enough, if rather unimaginatively monotonous:
SLAY THOSE WHO INSULT ISLAM. BUTCHER THOSE WHO MOCK ISLAM. [...]

This Is Taking Too Long

If Charles Darwin were alive, he’d be 200 years old today, and there has been an enormous outpouring of ink commemorating the great man’s bicentennial.

Sorry, Charlie

February 12th being the 200th anniversary of the birth of Charles Darwin, the University of Chicago biologist Jerry Coyne has written a substantial essay on the status of science and religion in American culture 150 years after the publication of On The Origin Of Species, and on just how compatible the two really are. His [...]

Another Way To Look At Things

Tonight, though, I have an interesting little item for you natural-history buffs.

Is God Necessary?

I have said often in these pages that it seems likely that the human propensity for religion is a cognitive adaptation that has flourished because it tends to improve the cohesion of social groups, thereby increasing the fitness of those groups in competition against others. As David Sloan Wilson argues in his book Darwin’s Cathedral: [...]

Sorry, Charlie

After a century and a half, it appears the Anglican Church may finally have got round to apologizing to Charles Darwin for its sneering reception of The Origin of Species.
Better late than never, I suppose, though at this point it hardly matters; the approval of this archaic institution hardly seems relevant any longer.

The Meaning of Life, Continued

A couple of weeks ago I posted an essay in response to a post of Bill Vallicella’s on whether life might have an objective meaning. In his piece Bill argued that any attempt to offer a purely subjective interpretation must lead to an infinite regress, and therefore must be false. I responded, drawing on work [...]

Dr. William Vallicella, the Maverick Philosopher, is back in harness after a month-long layoff from blogging. I’m glad he’s back on the job: he is as interesting and provocative as always.

It is far too hot to write, or even think cogently.

Churchill Gets It

Like may others I am an admirer of Winston Churchill, and have lately been reading an excellent book by the managing editor of Newsweek, Jon Meacham.

Life In The Fast Lane

Here’s Richard Dawkins, opening a conversation with J. Craig Venter at a recent conference in Germany:

Bill Of Goods

In his recent New York Times Magazine article on the evolutionary and biological underpinnings of morality, Steven Pinker acknowledges the nihilistic shadows nearby, and, like other popularizers of Darwinian naturalism, reassures us that we needn’t worry. I think he’s right — we needn’t — but not for the reasons he suggests.

Moral Truths

As promised, Steven Pinker has written what I think will be seen as a a fairly important article for the New York Times Magazine about human morality. Having banged on the topic of morality a great deal myself lately, I encourage all of you to read it. I found little to disagree with, though his [...]

Short Shrift

A little while ago I ran across an interesting, if rather sad, item in the Physorg.com daily newsletter, having to do with the small stature of pygmies. Previous notions had been that having such wee bodies better adapted them to food shortages, or to moving about in dense forests, but neither of these explanations has [...]

Grasping the Nettle

In Daniel Dennett’s most important book, Darwin’s Dangerous Idea, he makes with brilliant clarity the case that Darwin’s great insight — arguably, I think, the greatest ever had by anyone, so far at least — is, as Dennett calls it, a “universal acid”, eating at the foundations of many of Man’s [...]

Euthyphro and Con

The discussion of Divine Command Theory linked to in yesterday’s post is fascinating for me in more ways than one. I find it of interest not only in itself, as a thoughtful examination of an ancient and vexatious philosophical problem, but also on another, deeper level as well.

Watson In The Dock

A couple of days ago the Nobel laureate James Watson was all over the news: he had expressed, in an interview for the London Times, his opinion that scientific results indicated that black Africans were, on average, less intelligent than white Northerners. In a subsequent article, we read:

Dem Bones

An article in today’s Times raises an interesting issue. The story concerns a Dr. Marcus Ross, who was recently awarded a Ph.D. in paleontology by the University of Rhode Island. His professors all seem to agree that he did good solid scientific work in the pursuit of his degree, but there is one curious wrinkle: the newly minted Dr. Ross is a young-earth creationist.

A Deep Misunderstanding

Readers will probably be familiar with one Deepak Chopra, who has made a handsome pile over the years by peddling pseudo-scientific New Age pablum to legions of credulous and uncritical admirers. Now, in an item at the Huffington Post, he swivels his intellectual popguns to bear upon Richard Dawkins’s book The God Delusion, and does about as little damage as you might expect. If you enjoy seeing intellectual justice in action, visit the website eclexys, where blogger “gordsellar” gives Chopra’s gormless review, which is a basinful of the purest hogwash, the fisking it deserves, in a post entitled Deepak Chopra: Who Is This Idiot?

Thank you Kevin Kim for linking to this post, which I might otherwise have missed.

Not To Worry

As I’ve mentioned recently, there is always something at Edge.org to engage the curious mind. One of the more interesting features of the website is the annual World Question project, which consists of asking a diverse collection of thinkers some simple but provocative question, and presenting their responses.

Dairy Selection

In yesterday’s post we noted the difficulty people naturally have in grasping the immensity of the timeframe at which evolution occurs. But despite the zoomed-in view our fleeting lifespans impose upon us, we can still detect the occasional tick of the evolutionary clock. Just such an observation has recently been made regarding the genetic trait known as lactose tolerance.

Time Trouble

I often wonder why some people are so resistant to Darwinism. The idea, once grasped, would seem to have everything going for it: it is elegant and simple, but despite its simplicity has amazing depth and explanatory power. It has been abundantly confirmed, by a diverse yet mutually supporting body of evidence, and provides a sturdy framework for our understanding of all life on Earth.

Nevertheless, the fact of Darwinian evolution is flatly rejected by a majority (!) of Americans. One obvious reason for this is the pernicious persistence of fundamentalist Biblical literalism in our country, with its irrational insistence upon the Old Testament creation myth. But the acceptance of such folklore as fact is abetted by another, quite natural difficulty: people have, generally, absolutely no concept of deep time.

It’s Not Rocket Science

I receive a number of daily newsletters. Among them is one from Physorg.com, a website that serves as a clearinghouse for news on various scientific fronts. The stories are generally brief, rarely very technical, and their purpose is simply to alert the reader to the fact that that some new development or other has occurred in the field at hand; the curious reader may then, having been given the scent, follow it to its source on his own initiative. The whole thing is usually very professionally done, and is an excellent way to keep abreast of current events in science and technology.

Imagine my disappointment, then, to observe that Darwin’s theory of evolution by natural selection, the utter incomprehension of which we may sadly take as a “given” among its many detractors in religious circles, is also a source of confusion, even at the broadest and most superficial level, to the editors of the Physorg newsletter. I refer to the following headline, found atop a story in yesterday’s issue:

Do galaxies follow Darwinian evolution?

What is it that bothers me so? Read on.

The Narrow Way

However you may feel about Richard Dawkins’ recent campaign against religion, he is indisputably among the greatest living scholars of natural history. One of the many fascinating ideas he discusses in his richly informative book The Ancestor’s Tale is the notion that “evolvability” itself may be amenable to natural selection. He suggests that certain watershed developments in life’s history greatly increased the facility of organisms to adapt, and that such developments would have themselves been adaptive. There is tricky footing here; it is important to keep in mind that natural selection never “looks ahead”. But, as Dawkins writes near the end of the book, “we might find with hindsight that the species that fill the world tend to be descended from ancestral species with a talent for evolution.” There are a number of developments that Dawkins cites as having improved life’s “evolvability”: among these are the birth of eukaryotic cells, multicellularism, segmentation, and sex. He also discusses another, less obvious milestone: bottlenecking.

Turn of the Tide

I’ve mentioned oysters before in these pages (I should probably give posts about them a separate category by now), but while scooping a few dozen of them out of Wellfleet Harbor this weekend, I noticed something about them that I hadn’t realized before, which is that they seem to exhibit a consistent chirality.

Great Minds Think Alike

Here’s an interesting bit of convergent evolution: I see from an item in today’s PhysOrg newsletter that tarantula venom targets the same pain-inducing capsaicin receptors that plants such as chili peppers have learned to activate to discourage predators. Learn more here.

Scientific Creativity, East and West

My friend Eugene Jen has sent me some links to a lively academic discussion. The topic is one that I am keenly interested in — evolutionary psychology — and the question at hand is what the future of the field might be, both here in the USA and in Asia.

Rings and Bridges

Yesterday’s post was about “ring species”, both as interesting natural phenomena in themselves, and as a reminder that the persistent human tendency to impose discrete categories on continuous phenomena can lead us, if not to outright error, at least to an inaccurate model of the world. Keeping in mind that we are all inclined toward this prejudice — Richard Dawkins calls it the “tyranny of the discontinuous mind” — can help us to avoid not only taxonomic pitfalls, but philosophical ones as well.

Circle of Life

One of the obstacles that some people face in understanding evolutionary theory is the natural tendency to think in discrete terms, parsing the continuity of the world into distinct categories. Richard Dawkins, in his book The Ancestor’s Tale, addresses this problem — which he calls “the tyranny of the discontinuous mind” — and offers some examples of how the categories we see in the natural world are not sharply bounded, but merge quite seamlessly into one another. I have promised to write about some of the fascinating ideas in this book, and this topic seems a good one to begin with.

Tree of Life: A Reader Comments

In a recent post, I recommended that readers with an interest in biology pay a visit to the Tree of Life Web Project, an interactive display of the taxonomic relationships linking all life on Earth. Upon seeing the post, one of our commenters, microbiologist Andrew Staroscik, mentioned that he had rather a low opinion of [...]

That’s Life

As I mentioned a while back, one item getting frequent play in my rotating reading stack is the hefty volume The Ancestor’s Tale by Richard Dawkins, and as I expected, it is hugely engaging and informative. I’m about halfway done with it – the backwards pilgrimage is currently marching through the latter Carboniferous period, where we mammals have just been joined by the Sauropsids (including all reptiles and birds) . I’ve already learned a great many interesting things, and will be sprinkling some of them about these pages in days and weeks to come. For today, however, I’ll call the attention of any of you who have an interest in natural history to a marvelous website, the Tree of Life Web Project. Onto the sidebar it goes.

The Long March

There is more I’d like to say about Robert Wright’s Nonzero, and I’ll be getting to it tomorrow, most likely, but meanwhile I’ve just begun reading The Ancestor’s Tale, by Richard Dawkins.
