A wonderful conversation between four great men who in this video I like to call the Four Musketeers.  Each approaches this constant idealogical battle in their own style, taking their distinct backgrounds to lay a unified argument in the fight against superstition, myth and religion.  Richard Dawkins provides a biological and evolutionary insight, while Christopher Hitchens offers his unique form of eloquent logic and reason.  Sam Harris enlightens us through the neuroscience perspective and finally Daniel Dennett applies philosophical reasoning.  All for one and one for all.  It is refreshing to listen to a discussion and have the chance to make up your own mind, unlike fundamental evangelists who tell you how to think and act. Enjoy!
