Science Warriors' Ego Trips - The Chronicle Review - The Chronicle of Higher Education - 0 views

By Carlin Romano Standing up for science excites some intellectuals the way beautiful actresses arouse Warren Beatty, or career liberals boil the blood of Glenn Beck and Rush Limbaugh. It's visceral.
-
A brave champion of beleaguered science in the modern age of pseudoscience, this Ayn Rand protagonist sarcastically derides the benighted irrationalists and glows with a self-anointed superiority. Who wouldn't want to feel that sense of power and rightness?
-
You hear the voice regularly—along with far more sensible stuff—in the latest of a now common genre of science patriotism, Nonsense on Stilts: How to Tell Science From Bunk (University of Chicago Press), by Massimo Pigliucci, a philosophy professor at the City University of New York.

it mixes eminent common sense and frequent good reporting with a cocksure hubris utterly inappropriate to the practice it apotheosizes.
-
According to Pigliucci, both Freudian psychoanalysis and Marxist theory of history "are too broad, too flexible with regard to observations, to actually tell us anything interesting." (That's right—not one "interesting" thing.) The idea of intelligent design in biology "has made no progress since its last serious articulation by natural theologian William Paley in 1802," and the empirical evidence for evolution is like that for "an open-and-shut murder case."
-
Pigliucci offers more hero sandwiches spiced with derision and certainty. Media coverage of science is "characterized by allegedly serious journalists who behave like comedians." Commenting on the highly publicized Dover, Pa., court case in which U.S. District Judge John E. Jones III ruled that intelligent-design theory is not science, Pigliucci labels the need for that judgment a "bizarre" consequence of the local school board's "inane" resolution. Noting the complaint of intelligent-design advocate William Buckingham that an approved science textbook didn't give creationism a fair shake, Pigliucci writes, "This is like complaining that a textbook in astronomy is too focused on the Copernican theory of the structure of the solar system and unfairly neglects the possibility that the Flying Spaghetti Monster is really pulling each planet's strings, unseen by the deluded scientists."
-
Or is it possible that the alternate view unfairly neglected could be more like that of Harvard scientist Owen Gingerich, who contends in God's Universe (Harvard University Press, 2006) that it is partly statistical arguments—the extraordinary unlikelihood eons ago of the physical conditions necessary for self-conscious life—that support his belief in a universe "congenially designed for the existence of intelligent, self-reflective life"?
-
Even if we agree that capital "I" and "D" intelligent-design of the scriptural sort—what Gingerich himself calls "primitive scriptural literalism"—is not scientifically credible, does that make Gingerich's assertion, "I believe in intelligent design, lowercase i and lowercase d," equivalent to Flying-Spaghetti-Monsterism? Tone matters. And sarcasm is not science.
-
The problem with polemicists like Pigliucci is that a chasm has opened up between two groups that might loosely be distinguished as "philosophers of science" and "science warriors."
-
Philosophers of science, often operating under the aegis of Thomas Kuhn, recognize that science is a diverse, social enterprise that has changed over time, developed different methodologies in different subsciences, and often advanced by taking putative pseudoscience seriously, as in debunking cold fusion
-
The science warriors, by contrast, often write as if our science of the moment is isomorphic with knowledge of an objective world-in-itself—Kant be damned!—and any form of inquiry that doesn't fit the writer's criteria of proper science must be banished as "bunk." Pigliucci, typically, hasn't much sympathy for radical philosophies of science. He calls the work of Paul Feyerabend "lunacy," deems Bruno Latour "a fool," and observes that "the great pronouncements of feminist science have fallen as flat as the similarly empty utterances of supporters of intelligent design."
-
It doesn't have to be this way. The noble enterprise of submitting nonscientific knowledge claims to critical scrutiny—an activity continuous with both philosophy and science—took off in an admirable way in the late 20th century when Paul Kurtz, of the University at Buffalo, established the Committee for the Scientific Investigation of Claims of the Paranormal (Csicop) in May 1976. Csicop soon after launched the marvelous journal Skeptical Inquirer
-
Although Pigliucci himself publishes in Skeptical Inquirer, his contributions there exhibit his signature smugness. For an antidote to Pigliucci's overweening scientism 'tude, it's refreshing to consult Kurtz's curtain-raising essay, "Science and the Public," in Science Under Siege (Prometheus Books, 2009, edited by Frazier)
-
Kurtz's commandment might be stated, "Don't mock or ridicule—investigate and explain." He writes: "We attempted to make it clear that we were interested in fair and impartial inquiry, that we were not dogmatic or closed-minded, and that skepticism did not imply a priori rejection of any reasonable claim. Indeed, I insisted that our skepticism was not totalistic or nihilistic about paranormal claims."
-
Kurtz combines the ethos of both critical investigator and philosopher of science. Describing modern science as a practice in which "hypotheses and theories are based upon rigorous methods of empirical investigation, experimental confirmation, and replication," he notes: "One must be prepared to overthrow an entire theoretical framework—and this has happened often in the history of science ... skeptical doubt is an integral part of the method of science, and scientists should be prepared to question received scientific doctrines and reject them in the light of new evidence."
-
Pigliucci, alas, allows his animus against the nonscientific to pull him away from sensitive distinctions among various sciences to sloppy arguments one didn't see in such earlier works of science patriotism as Carl Sagan's The Demon-Haunted World: Science as a Candle in the Dark (Random House, 1995). Indeed, he probably sets a world record for misuse of the word "fallacy."
-
To his credit, Pigliucci at times acknowledges the nondogmatic spine of science. He concedes that "science is characterized by a fuzzy borderline with other types of inquiry that may or may not one day become sciences." Science, he admits, "actually refers to a rather heterogeneous family of activities, not to a single and universal method." He rightly warns that some pseudoscience—for example, denial of HIV-AIDS causation—is dangerous and terrible.
-
But at other points, Pigliucci ferociously attacks opponents like the most unreflective science fanatic
-
He dismisses Feyerabend's view that "science is a religion" as simply "preposterous," even though he elsewhere admits that "methodological naturalism"—the commitment of all scientists to reject "supernatural" explanations—is itself not an empirically verifiable principle or fact, but rather an almost Kantian precondition of scientific knowledge. An article of faith, some cold-eyed Feyerabend fans might say.
-
He writes, "ID is not a scientific theory at all because there is no empirical observation that can possibly contradict it. Anything we observe in nature could, in principle, be attributed to an unspecified intelligent designer who works in mysterious ways." But earlier in the book, he correctly argues against Karl Popper that susceptibility to falsification cannot be the sole criterion of science, because science also confirms. It is, in principle, possible that an empirical observation could confirm intelligent design—i.e., that magic moment when the ultimate UFO lands with representatives of the intergalactic society that planted early life here, and we accept their evidence that they did it.
-
"As long as we do not venture to make hypotheses about who the designer is and why and how she operates," he writes, "there are no empirical constraints on the 'theory' at all. Anything goes, and therefore nothing holds, because a theory that 'explains' everything really explains nothing."
-
Here, Pigliucci again mixes up what's likely or provable with what's logically possible or rational. The creation stories of traditional religions and scriptures do, in effect, offer hypotheses, or claims, about who the designer is—e.g., see the Bible.
-
Far from explaining nothing because it explains everything, such an explanation explains a lot by explaining everything. It just doesn't explain it convincingly to a scientist with other evidentiary standards.
-
A sensible person can side with scientists on what's true, but not with Pigliucci on what's rational and possible. Pigliucci occasionally recognizes that. Late in his book, he concedes that "nonscientific claims may be true and still not qualify as science." But if that's so, and we care about truth, why exalt science to the degree he does? If there's really a heaven, and science can't (yet?) detect it, so much the worse for science.
-
Pigliucci quotes a line from Aristotle: "It is the mark of an educated mind to be able to entertain a thought without accepting it." Science warriors such as Pigliucci, or Michael Ruse in his recent clash with other philosophers in these pages, should reflect on a related modern sense of "entertain." One does not entertain a guest by mocking, deriding, and abusing the guest. Similarly, one does not entertain a thought or approach to knowledge by ridiculing it.
-
Long live Skeptical Inquirer! But can we deep-six the egomania and unearned arrogance of the science patriots? As Descartes, that immortal hero of scientists and skeptics everywhere, pointed out, true skepticism, like true charity, begins at home.
