On this week’s Skeptical Sunday, continuing last week’s theme on science denial, Lindsey Beyerstein interviews Donald Prothero on Point of Inquiry. He’s a paleontologist, geologist, and author of the new book Reality Check: How Science Deniers Threaten our Future. Prothero details how today’s more sophisticated science deniers imitate the trappings of science to advance a political agenda. Then, we look at Islamist extremism on a second Point of Inquiry. Josh Zepps interviews Farzana Hassan, a Pakistani-Canadian political scientist and columnist for the Toronto Sun, about dealing honestly with acts of Islamist terrorism. Hassan, herself a Muslim, suggests that there exists doctrinal support within Islam for many of the terrible acts we see today done in its name. Are moderate Muslims serving as a cover for the extremists and can moderate Muslims play a larger role limiting the influence of radicals? But first on Freethought Radio, Dan Barker and Annie Laurie Gaylor speak with two authors from the Boston area. First is Rebecca Newberger Goldstein who has a new book entitled Plato At The GooglePlex: Why Philosophy Won’t Go Away. Then they interview Megan Marshall, author of the Pulitzer-Prize winning biography, Margaret Fuller: A New American Life.
