The internet is an astonishing resource, as evidenced by this conference that you can view online. Join me in watching some of the world's biggest names in science discuss matters of religion and belief. I've had time to view only Session 4, with Hameroff and Ramachandran, and can hardly wait to view the rest. There is a tremendous wealth of material here for personal study or for your class. The main disadvantage is that these are video streams, so you'll need a fast internet connection. The discussion is absolutely fascinating, and worth your time. Stop what you're doing and visit http://beyondbelief2006.org/Watch/. You'll be glad you did!
