Summary
This week we were honored to interview Ray Scott Percival, a significant but also woefully under-appreciated figure in critical rationalism. Percival has been active in critical rationalist forums, conferences, and academic journals since the 90s and before. He has written for Quillette. He was the editor of a book of critical responses to Steven Pinker. He created an excellent documentary film called Liberty Loves Reason. But most significantly, in 2012 he wrote a book called Myth of the Closed Mind, which is available on Amazon in all the formats, including audio. The basic idea he explores there is that humans care about truth. We are truth seekers that create and pass on both rational and irrational memes. Dawkins calls the worst of these memes “mind viruses,” but what Percival points out is that as flawed as humans are, the good kind of memes have a competitive advantage in the war of ideas. Such a simple idea, but the implications of this are profound, and Percival has spent a lifetime wresting with them.
