Salon.com has a good interview with Ronald Numbers, historian at the University of Wisconsin and author of the newly reissued The Creationists.
Raised in a fundamentalist home, being "never exposed to anything other than what we now call 'young earth creationism,'" Numbers still counts among his family and friends a number of people who believe in a literal reading of the first chapters of Genesis. In his work as a historian, Numbers is less interested in proving them wrong than in understanding them. This is something that, in the current evolution-creation debate, many of us neglect.
