Pigliucci and Boudry rebuke alternative medicine, praise science, in New York Times

A little over a week ago Jerry noted a puzzling piece on the New York Times website by Stephen Asma that praised the theory of “Qi” and drinking turtle blood as interesting and worthwhile concepts. Jerry had a go at some of Asma’s confusions, and now in the Times Massimo Pigliucci and Maarten Boudry have their turn at bat, with Asma being the ball.

In their piece, called “The Dangers of Pseudoscience”, Pigliucci and Boudry note why it is useful to distinguish between science and pseudoscience, and emphasize especially the importance of doing so with regard to medical claims.

Asma’s example of Chinese medicine’s claims about the existence of “Qi” energy, channeled through the human body by way of “meridians,” though, is a different matter [than aspirin]. This sounds scientific, because it uses arcane jargon that gives the impression of articulating explanatory principles. But there is no way to test the existence of Qi and associated meridians, or to establish a viable research program based on those concepts, for the simple reason that talk of Qi and meridians only looks substantive, but it isn’t even in the ballpark of an empirically verifiable theory.

They stress the importance of understanding the underlying causes of phenomena (e.g. the placebo effect), rather than applying fanciful words to the phenomena. They appropriately note that, “The notion of Qi, again, is not really a theory in any meaningful sense of the word. It is just an evocative word to label a mysterious force of which we do not know and we are not told how to find out anything at all.”  They rightfully conclude

The borderlines between genuine science and pseudoscience may be fuzzy, but this should be even more of a call for careful distinctions, based on systematic facts and sound reasoning. To try a modicum of turtle blood here and a little aspirin there is not the hallmark of wisdom and even-mindedness. It is a dangerous gateway to superstition and irrationality.

Pigliucci on Sagan

August 26, 2009 • 5:27 pm

Over at Rationally Speaking, Massimo Pigliucci, who seems to have moved from SUNY to CUNY, has a nice post on Carl Sagan’s challenges to theology. A snippet:

As Douglas Adams famously put it in The Hitchhiker’s Guide to the Galaxy: “Space is big. You just won’t believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it’s a long way down the road to the drug store, but that’s just peanuts to space.” Indeed. What sort of intelligent engineer would create a contraption (the universe) that takes upwards of 13 billion years to generate Homo sapiens, all the while wasting 99.999999999999+ percent of the space in the universe? Or maybe, suggests Sagan, this vast amount of space and time hasn’t been wasted, and God has created many other worlds with people. But in that case, did Jesus come and die on the cross in every single one of them? Are there separate Hells and Heavens for different species of ET? The theological implications are staggering, and yet completely unaddressed.

Ah, the religious will say, but who are we to question God’s plan? He (or she, or it, as Sagan repeatedly writes) notoriously works in mysterious ways. But that is the ultimate cop out. It is simply a fancy, and frankly insulting, way to say “I haven’t the foggiest idea.” People have a right to believe whatever inane story they like to believe (as long as they do not try to impose it on others), but many religious people since Thomas Aquinas actually want to argue that their beliefs are also rational, that there is no contradiction between the book of nature and those of scripture. If so, then they need to answer Sagan’s question about why it is that the so-called holy books don’t tell us anything at all about how the universe really is.

Sagan imagines how God could have dictated his books to the ancient prophets in a way that would have certainly made an impact on us moderns. He could have said (I’m quoting Sagan directly here): “Don’t forget, Mars is a rusty place with volcanoes. … You’ll understand this later. Trust me. … How about, ‘Thou shalt not travel faster than light?’ … Or ‘There are no privileged frames of reference.’ Or how about some equations? Maxwell’s laws in Egyptian hieroglyphics or ancient Chinese characters or ancient Hebrew.” Now that would be impressive, and even Dawkins would have to scratch his head at it. But no, instead we find trivial stories about local tribes, a seemingly endless series of “begats,” and a description of the world as small, young, and rather flat.

Sagan’s challenge is virtually ignored by theologians the world over. And for good reason: it is impossible to answer coherently while retaining the core of most religious traditions. The various gods people worship are simply far too small for the universe we actually inhabit, which is no surprise once we accept the rather obvious truth that it is us who made the gods in our image, not the other way around. We miss you, Carl.
