Michael Ruse is a philosopher of science who has just released this new book that talks about creationism and evolutionism. Most here will probably disagree with him, but one thing I think he does very nicely is point out that 'fundamentalist evolutionism' is just as much a religious position as fundamentalist creationism. (People here, of all people, should realise that calling a position 'religious' is not disrespecting it, just describing it.)

There's an interview with Michael Ruse and a mini-review of the book here: http://www.salon.com/books/int/2005/08/06/ruse/index.html (Salon link, you'll have to view an ad if you don't subscribe)
