John Gray looks to history to argue that it's time to rethink today's narrow view of atheism.
He ponders the lives of two little known atheists from the past - the nineteenth century Italian poet Giacomo Leopardi and the Somerset essayist and novelist Llewelyn Powys. He says their work shows how atheism can be far richer and subtler than the version we're familiar with.
"The predominant strand of contemporary unbelief , which aims to convert the world to a scientific view of things, is only one way of living without an idea of God" writes Gray.
