Known as the `four horsemen` of New Atheism, these four big thinkers of the twenty-first century met only once. Their electrifying examination of ideas on this remarkable occasion was intense and wide-ranging. Everything that was said as they agreed and disagreed with one another, interrogated ideas and exchanged insights - about religion and atheism, science and sense - speaks with urgency to our present age. Questions they asked of each other included: `Is it ever possible to win a war of ideas? Is spirituality the preserve of the religious? Are there any truths you would rather not know? Would you want to see the end of faith?` The dialogue was recorded, and is now transcribed and presented here with new introductions from the surviving three horsemen. With a sparkling introduction from Stephen Fry, it makes essential reading for all their admirers and for anyone interested in exploring the tensions between faith and reason.
