Known as the ‘four horsemen’ of New Atheism, these four big thinkers of the 21st 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. 

Should we believe in God? Do we need God in order to explain the existence of the universe? Do we need God in order to be good? In 12 chapters that address some of the most profound questions human beings confront, Dawkins marshals science, philosophy and comparative religion to interrogate the hypocrisies of all the religious systems and explain to listeners of all ages how life emerged without a Creator, how evolution works and how our world came into being.

In the tradition of Bertrand Russell's Why I Am Not a Christian and Sam Harris' The End of Faith, Christopher Hitchens makes the ultimate case against religion. With a close and erudite reading of the major religious texts, he documents the ways in which religion is a man-made wish, a cause of dangerous sexual repression and a distortion of our origins in the cosmos. 

Sam Harris has discovered that most people, from secular scientists to religious fundamentalists, agree on one point: science has nothing to say on the subject of human values. Indeed, science’s failure to address questions of meaning and morality has become the primary justification for religious faith.The underlying claim is that while science is the best authority on the workings of the physical universe, religion is the best authority on meaning, values, morality, and leading a good life.

Cosmos is one of the bestselling science books of all time. In clear-eyed prose, Sagan reveals a jewel-like blue world inhabited by a life form that is just beginning to discover its own identity and to venture into the vast ocean of space.
