Case in Point

No sooner do I post a meditation on how biologists might profit from a little philosophical training than along comes an article to illustrate the very point I was making.

First a little background. Philosopher of science Stephen Meyer, author of Signature in the Cell, a recently released book on the evidence for intelligent design found in the cells of living things, wrote a brief piece on ID for the Boston Globe. In it Meyer mentioned that Thomas Jefferson was sympathetic to design as an explanation for natural phenomena.

This affront to Mr. Jefferson's honor was evidently more than a young gentleman and science writer by the name of Ewen Callaway could bear. Rising to defend the reputation of the defamed Mr. Jefferson against Meyer's unconscionable calumny, Callaway wrote a rebuttal which is currently appearing at New Scientist.

Callaway's refutation of Meyer consists in deriding his claim that Jefferson approved of the design hypothesis by stating in no uncertain terms that Jefferson was staunch in his belief in the separation of church and state and would never have approved of teaching ID in public schools.

I know you're scratching your head wondering what teaching ID in schools has to do with being sympathetic to the notion of a cosmic designer, but that's what Mr. Callaway said. You can check it out for yourself at the link.

Meyer never mentioned anything about teaching ID in public schools, and in fact the organization he represents, The Discovery Institute, is decidedly cool to the idea, but that doesn't deter Mr. Callaway. See if you can follow the logic here:

For a newspaper fighting for its survival, The Boston Globe has picked a peculiar time to run an absurdly-reasoned opinion piece supporting intelligent design.

Penned by the Discovery Institute's Stephen C. Meyer, the essay makes the ridiculous assertion that Thomas Jefferson - author of the Declaration of Independence and the third US president - espoused intelligent design.

Meyer sees supports for this claim in an 1823 letter Jefferson wrote to the second US president John Adams: "It is impossible, I say, for the human mind not to believe that there is, in all this, design, cause and effect, up to an ultimate cause, a fabricator of all things from matter and motion."

Fair enough. Though he may not have been a Christian in the strictest sense, Jefferson was deeply spiritual, and he invoked a creator in arguing for universal human rights - "life, liberty, and the pursuit of happiness."

Now, Callaway had led us to believe he would give us a fulminating rejoinder to Meyer's libel of Mr. Jefferson, but in the event he meekly admits that Meyer is right. This is a rather peculiar way to go about discrediting an opponent's argument, and it seems as if Callaway at some level senses his blunder. Seeking to recover the thread of his objection he goes on to inform us of what Meyer doesn't say about Jefferson:

Jefferson was also a dogged supporter of the separation of church and state. Meyer brushes this aspect of his biography aside: "By invoking Jefferson's principle of separation, many critics of intelligent design assume that this visionary Founding Father would agree with them."

Public schools didn't exist in their current form in America during Jefferson's time, but Meyer never pauses to consider whether Jefferson would have supported the teaching of ID - a religious philosophy - in government-funded schools. He wouldn't have.

So there. ID is religion, don't you know, and Jefferson would have had none of it in public schools if there were such things back then, therefore Jefferson was not sympathetic to purposeful design, and Meyer is a big boob for saying that he was. Or something like that. I don't have it all figured out yet.

But Callaway is not done pelting Meyer's Globe article with rhetorical wiffle balls:

Meyer's argument eventually devolves into ID gobbeldy [sic]-gook:

[Meyer writes that] "Of course, many people assume that Jefferson's views, having been written before Darwin's Origin of Species are now scientifically obsolete. But Jefferson has been vindicated by modern scientific discoveries that Darwin could not have anticipated."

Vindicated how? By the discovery of DNA, of course.

Meyer cannot accept that the genetic code evolved naturally. Never mind the fact that the building blocks of DNA and its cousin molecule RNA existed on early Earth and even in space. Scientists are also making increasing progress in understanding how these chemicals might have stitched themselves together and how they began replicating and evolving.

Callaway oddly faults Meyer for failing to believe what no one has ever demonstrated to be even possible, that specified complexity - meaningful, functional information - can be produced by something other than a mind. Neither Callaway nor anyone else can say how the coded information on the DNA molecule could have arisen purely by natural, physical processes, but this fact is of no consequence when you just know that somehow it must have happened.

To say that the existence of the building blocks of DNA were present in the early earth, something Mr. Callaway can't possibly know, and that therefore it's a mere hop, skip and a jump to self-replicating, protein transcribing, cell regulating nucleic acid molecules is called "wave of the wand" theorizing. It's equivalent to saying that if a billion monkeys were afforded access to typewriters the complete works of Shakespeare would be inevitable. Given the myriad difficulties and improbabilities, why should anyone believe such a thing?

Callaway, like a desperate boxer who finds himself losing to a superior opponent in the final round, swings wildly at Meyer hoping for a knockout, but all he does is embarrass himself:

Instead Meyer pulls out the same lazy, wrongheaded argument that intelligent design supporters have been pushing since the philosophy was adapted from creationism - if something looks designed, it must have been...

Well, so far it's Mr. Callaway who bears the trophy for lazy and wrongheaded. And also ignorant. If he were better informed he would be aware that the Cambridge-educated Dr. Meyer has just written a marvelously researched 508 page book on the very topic upon which Mr. Callaway is at such pains to demonstrate his ignorance. I wonder whether Mr. Callaway has made the effort to read Meyer's book or whether he finds it more agreeable and less intellectually taxing to simply go about waving the wand and launching ineffectual haymakers.
