"There is, of course, much that is wise and consoling and beautiful in our religious books. But words of wisdom and consolation and beauty abound in the pages of Shakespeare, Virgil and Homer as well, and no one ever murdered strangers by the thousands because of the inspiration he found there. The belief that certain books were written by God (who, for reasons difficult to fathom, made Shakespeare a far better writer than himself) leaves us powerless to address the most potent source of human conflict, past and present.
How is it that the absurdity of this idea does not bring us, hourly, to our knees? It is safe to say that few of us would have thought so many people could believe such a thing, if they did not actually believe it. Imagine a world in which generations of human beings come to believe that certain films were made by God or that specific software was coded by him. Imagine a future in which millions of our descendants murder each other over rival interpretations of Star Wars or Windows 98. Could anything-anything-be more ridiculous? And yet, this would be no more ridiculous than the world we are living in. "

-Sam Harris, from his sprawling, flawed, hyperbolic and long overdue book: The End of Faith.
