This is probably a bit de trop, because I suspect that many watched it as broadcast – but those who haven’t seen Terry Pratchett‘s Dimbleby Lecture can watch it here; I believe that most things on the iplayer get taken down after a while, but I can’t see any indication of there being a limited time for this, so am assuming that it’s going to be available indefinitely. It’s funny, impassioned and well worth a watch. I’ll keep an eye out for the availability of a transcript – if anyone finds it, let me know, and I’ll provide a link here.
(It’s worth a mention, too, that he cites this 2007 JME paper.)
UPDATE: Thanks to Dr Gubernaculum for directing me to this shortened version of the lecture.
