The Pew Forum on Religion and Public Life organized a conversation between the Hitchens brothers on the topic 'Can Civilization Survive Without God?' last month.
Christopher Hitchens is famous for his popular book 'God Is Not Great: How Religion Poisons Everything' in 2007. His brother, Peter Hitchens, published 'The Rage Against God: How Atheism Led Me to Faith' in this year as an indirect response to Christopher.
CNN.com has covered the news on their website with a short video clip of the conversation.
The entire transcript is available at the organizer's website.
