It’s a longstanding debate in the philosophy of science: Is "demarcation" possible? Can we really draw firm lines between science and pseudoscience?
Massimo Pigliucci thinks so. In his new book Nonsense on Stilts: How to Tell Science from Bunk, Pigliucci attempts to rescue the notion that there are claims we can rule out, and claims we can rule in—a real means of determining what’s science and what isn’t.
Along the way, Pigliucci touches on howlers like creationism and astrology, and borderland areas of research like SETI—and weighs whether science can ever hope to test claims about the supernatural.
Massimo Pigliucci is chair of the philosophy department at CUNY-Lehman College. He was formerly a professor of ecology and evolution at Stony Brook. He’s a prolific blogger and commentator on issues concerning science and skepticism and a prominent battler of creationists and other nonsense peddlers.

I enjoy his podcasts. I have his book in my Nook, ready to read next.
[10:05] “So those are two really interesting cases where the falsification criterion couldn’t possibly be applied to both cases. And it shows very nicely why falsification doesn’t work… do we have an alternative? [with a breath of released tension]”
:bug: So he’s falsified falsification theory. Okay…
Bayesian Theory?
I do love to read Pigliucci’s articles. :)

Me too! although I don’t always agree with him. I am waiting for an hour when nothing can interrupt me, to enjoy the podcast!
Science is a thought process.
EVERYBODY has to be a scientist.
Kids need to be encouraged to think in grade school not told what to think.

It’s not clear to me what Pigliucci’s suggested Bayesian approach to the demarcation problem is. He says something to the effect that those who adjust their probabilities in accordance to the evidence are doing science, and those who don’t aren’t. But that leaves open the question of what counts as evidence and whose evidence counts, and may entail that some scientists aren’t doing science and some pseudoscientists are.
The philosopher Philip Kitcher, in his book _The Advancement of Science_, proposed that the science/pseudoscience distinction bestreduces to a scientist/pseudoscientist distinction, in that scientists are those who participate in the community of scientists and do work recognized as science by scientists, while pseudoscientists don’t. Pigliucci’s view, on one possible interpretation, seems similar.
