Great article Graham, with lots of new information that will be very useful as I continue to explore the top-down or bottom-up question. In your discussion with Dohan, you might mention a couple of points. One is that Karl Popper in addition to talking about falsifiability also coined the term "promissory materialism" which Mr. Dohan appears to subscribe to.

Also, one of the most interesting examples that undermines the production model of the mind/brain question is from leading neuroscientist Christof Koch. Studies of mystics undermine the physicalist ideas (as documented in Kellys' works) but also by Koch in his own experience in a sensory deprivation tank. The experience is extraordinarily rich, vivid, emotional, meaningful, filled with memories--yet the neuro activity is minimal or even disappears. As Koch mentioned in an interview published on Medium, this may undermine his much favored theory called IIT or Integrated Information Theory. That is mentioned here: https://medium.com/@gerald.baron/what-if-mind-doesnt-emerge-from-the-brain-what-might-that-mean-for-science-dbeb15ad2ddb
