Conversation Theory in One Hour

I was invited to give a presentation about Gordon Pask and his Conversation Theory at the annual conference of the American Society for Cybernetics in June 2016. My great friend and colleague, Jude Lombardi, has kindly produced and edited a video of my hour talk, which begins with an introduction to Pask as an experimentalist and “maker”. From this foundation Pask built a scientific theory of how conversation works, including a detailed formal “calculus of cognition.” He also offers the principle that consciousness is conserved in the same sense that physics says that matter and energy are conserved. My presentation slides of the talk are available here. You can see Pask himself in these videos. I discuss a collection of artifacts related to his work in this reminiscence. A number of his papers and books are available here, along with further links to related materials.
