I spent last Thursday and Friday at the Unchallengeable Orthodoxies conference hosted by the ASU Sandra Day O’Connor Law School in conjunction with the University of Cambridge. Lots of interesting discussion on academic freedom, scientific practice and suchlike. I presented a 20 minute case study on why I felt that evolution was not an unchallengeable orthodoxy and why creationist claims about being stifled or expelled do not hold up when examined in light of scientific practice and the history of science. It’s a talk that I’m working up into a longer version to be presented at the American Humanist Association Annual Meeting in June. That meeting is here in Tempe, and PZ Myers is to be receiving the Humanist of the Year award.
