Nick Spencer is the author of 'Atheists: The Origin of the Species'. He explains the origins of various strands of atheism and why the New Atheism of today is constructed on a myth of its own.

Julian Baggini is an atheist philosopher and writer. He engages Spencer on whether atheism was a significant factor in Communist regimes and what the future of atheism may hold.
