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.
