I've been watching that Beyond Belief series over the last 2 weeks, 10 sessions, each between 1 hour 30 minutes - 2 hours long, religious, scientific, humanist & ethical discussions and banter (amongst many others), great stuff! I finished the 10th session just now, Neil deGrasse Tyson's enthusiasm and bubbly character is impossible to resist, inspiring. I highly recommend it too, I've had great fun listening to it all recently. I look forward to Beyond Belief 2, in November I hear.
EDIT:
There was one story that I think will stick with me for a while, it was told by Ann Druyan. It was about her father and grandfather and the relationship they had, her grandfather was a devoutly religious man.
Anyway, her father slowly grew away from his religious upbringings and one day he came home to find his father praying, in a trance like state, it was this day that he had decided to be honest and open with his father about his beliefs or lack there of. His father, awakening from his trance, got up to hug him and Ann's father pushed him away, explaining that he needed to say something first. He then talked about all the things that bothered him, all the things he disagreed with about this belief system to which his father was so much a part of. And I gather from Ann's story, he was quite blunt about it all. The grandfather's simple reply to all this?
"Well the only sin, would be to pretend".
I think this says a lot.
