Massimo Pigliucci on the boundary between science and pseudoscience

In this video, Massimo Pigliucci, the philosopher and biologist who runs the Scientia Salon site, discusses the demarcation problem, the dividing line between what is and is not science.  The distinction is easy for things like astrology and astronomy, but gets more difficult for many other areas. http://www.youtube.com/watch?v=zBUKQWM5Jf0 I'd forgotten about Massimo's latest book on pseudoscience. … Continue reading Massimo Pigliucci on the boundary between science and pseudoscience
