Sheer Intellectual Laziness

Good William Dembski post.

excerpts:

John Derbyshire has written some respectable books on the history of mathematics (e.g., his biography of Riemann). He has also been a snooty critic of ID. Given his snootiness, one might think that he could identify and speak intelligently on substantive problems with ID. But in fact, his knowledge of ID is shallow, as is his knowledge of the history of science and Darwin’s writings. This was brought home to me at a recent American Enterprise Institute symposium. On May 2, 2007, Derbyshire and Larry Arnhart faced off with ID proponents John West and George Gilder. The symposium was titled “Darwinism and Conservatism: Friends or Foes.” The audio and video of the conference can be found here: www.aei.org/…/event.

Early in Derbyshire’s presentation he made sure to identified ID with creationism (that’s par for the course). But I was taken aback that he would justify this identification not with an argument but simply by citing Judge Jones’s decision in Dover, saying “That’s good enough for me.” To appreciate the fatuity of this remark, imagine standing before feminists who regard abortion for any reason as a fundamental right of women and arguing against partial birth abortions merely by citing some court decision that ruled against it, saying “That’s good enough for me.” Perhaps it is good enough for YOU, but it certainly won’t be good enough for your interlocutors. In particular, the issue remains what about the decision, whether regarding abortion or ID, makes it worthy of acceptance. Derbyshire had no insight to offer here.

What really drove home for me what an intellectual lightweight he is in matters of ID — even though he’s written on the topic a fair amount in the press — is his refutation specifically of my work. He dismissed it as committing the fallacy of an unspecified denominator. The example he gave to illustrate this fallacy was of a golfer hitting a hole in one. Yes, it seems highly unlikely, but only because one hasn’t specified the denominator of the relevant probability. When one factors in all the other golfers playing golf, a hole in one becomes quite probable. So likewise, when one considers all the time and opportunities for life to evolve, a materialistic form of evolution is quite likely to have brought about all the complexity and diversity of life that we see (I’m not making this up — watch the video).

But a major emphasis of my work right from the start has been that to draw a design inference one must factor in all those opportunities that might render probable what would otherwise seem highly improbable. I specifically define these opportunities as probabilistic resources – indeed, I develop a whole formalism for probabilistic resources.

...

[W]hether one is entitled to eliminate or embrace chance depends on how many opportunities chance has to succeed. It’s a point I’ve made repeatedly. Yet Derbyshire not only ignores this fact, attributing to me his fallacy of the unspecified denominator, but also unthinkingly assumes that the probabilsitic resources must, of course, be there for evolution to succeed. But that needs to be established as the conclusion of a scientific argument. It is not something one may simply presuppose.

There’s a larger issue at stake here. I’ve now seen on several occasions where critics of design give no evidence of having read anything on the topic — and they’re proud of it! I recall Everett Mendelson from Harvard speaking at a Baylor conference I organized in 2000 decrying intelligent design but spending the whole talk going after William Paley. I recall Lee Silver so embarrassing himself for lack of knowing anything about ID in a debate with me at Princeton that Wesley Elsberry chided him to “please leave debating ID advocates to the professionals” (go here for the Silver-Elsberry exchange; for the actual debate, go here). More recently, Randy Olson, of FLOCK OF DODOS fame, claimed in making this documentary on ID that he had read nothing on the topic (as a colleague at Notre Dame recently reported, privately, on a talk Randy gave there: “He then explained how he deliberately didn’t do research for his documentary, and showed some movie clips on the value of spontaneity in film making”). And then there’s Derbyshire.

These critics of ID have become so shameless that they think they can simply intuit the wrongness of ID and then criticize it based simply on those intuitions. The history of science, however, reveals that intuitions can be wrong and must themselves be held up to scrutiny. In any case, the ignorance of many of our critics is a phenomenon to be recognized and exploited. Derbyshire certainly didn’t help himself at the American Enterprise Institute by his lack of homework.


UPDATE--Here's a good comment to the post:

Maybe someone should point out a good refutation of the lottery example since it is a common argument used by Darwinists with the dare that “you cannot refute it.”

Try looking at it this way:

That someone will win a lottery is a near certainty.

Life forming from dust stirred up on your walk to the store is, well, not.

Why is someone winning a lottery a near certainty? Because a lottery is designed that way. In fact, if a particular lottery never has a winner you will be wise to assume — heh heh — it is designed that way.

So to correlate the winning lottery ticket to the inevitability of the existence of life one would have to presume life to be . . . . ?

Now, here’s something else to ponder based on the hole in one probability.

With thousands of golfers playing thousands of holes you can count on an occasional hole in one.

BUT suppose every golfer had some muscle condidtion that prevented him from hitting the ball more than 10 yards? And suppose all were blind? And suppose all were facing the wrong way? Even with a trillion billion trillion golfers playing on a trillion billion trillion Sundays could you ever except a hole in one with those conditions?

The existence of physical impossibility is reality.

It is impossible for life to exist by chance. It is inevitable for life to exist with the right Designer.
