The Root of All Evil? is a television documentary, written and presented by Richard Dawkins, in which he argues that the world would be better off without religion. The documentary was first broadcast in January 2006, in the form of two 45-minute episodes (excluding advertisement breaks), on Channel 4 in the UK.Dawkins has said that the title "The Root of All Evil?" was not his preferred choice, but that Channel 4 had insisted on it to create controversy. His sole concession from the producers on the title was the addition of the question mark. Dawkins has stated that the notion of anything being the root of all evil is ridiculous. Dawkins's book The God Delusion, released in September 2006, goes on to examine the topics raised in the documentary in greater detail. The God Delusion explores the unproven beliefs that are treated as factual by many religions and the extremes to which some followers have taken them. Dawkins opens the programme by describing the "would-be murderers . . . who want to kill you and me, and themselves, because they're motivated by what they think is the highest ideal." Dawkins argues that "the process of non-thinking called faith" is not a way of understanding the world, but instead stands in fundamental opposition to modern science and the scientific method, and is divisive and dangerous.
