The Straw Man, the Ad Hominem, the Appeal to Authority, Special Pleading, Anecdotal Evidence, the Appeal to Ignorance, the Non-Sequitur, and the Slippery Slope: these are the names given to some of the logical fallacies all of us fall into. In the same way that learning the names of birds is integral to becoming a better birder, so learning the names of these fallacies help us spot them when they come up in conversation, in the media, and even in our own heads. We’ll hear Brian Dunning run through some of these most common of these fallacies on Skeptoid, then David McRaney on the You Are Not So Smart podcast looks at one of these in depth: the “post-hoc ergo propter hoc” fallacy. Don’t speak Latin? Then you need to stay tuned to find out what that is. But why all this concern with thinking and arguing rationally, anyway, if by nature we’re so pre-disposed to think irrationally. After all, maybe irrationality makes us happier in certain situations. Philosopher Massimo Pigliucci and co-host Julia Galef step into the breach and defend rationality itself on the Rationally Speaking podcast. But first…On Freethought Radio Dan Barker and Annie Laurie Gaylor tell us about a landmark Minnesota church abuse case, give us the latest on their Freethought Hall expansion progress, and then interview two former ministers who no longer believe: ex-Lutheran Randy Bender and ex-Pentecostal Matt Killingsworth.
