Right off the bat, I would say Rupert Sheldrake. When he wasn't keeping you in stitches from his comedic wit, you would be learning things about science that most people just don't have a clue about. He started out as one of the most brilliant biologists, the UK has had in awhile, but became a heretic when he questioned the 10 dogmas of science, and materialism. If you guys ever get some time, find him on you tube and listen to him. He is the scientist who proved dogs know when their masters are coming home, by something like ESP. He believes the mind is outside the brain, as is memory. He doesn't buy that we are just lumbering robots, but something much, much greater. And a friend to the religious. Can you imagine that? A brilliant scientist who is not an atheist?
