Good luck with your radio venture. Obviously you will want to have interviews with articulate proponents of various views, if you can get them. Might also be interesting to have a section on historical issues as background, such as Jung's notion of archetypes in light of current theory. This would bring in a wider audience. Some of the work in comparative & developmental neuroscience would also be interesting to bring in. As far as I know this has not yet been done in a systematic or comprehensive manner. Not too easy, but should be fascinating! John Fentress
