I don't really know what it is about vampires that makes them such a powerful symbol, metaphor, whatever in people's consciousness. But I do know they're tremendously powerful. I mean, there's a vampire on 'Sesame Street.' And Count Chocula. I don't know why it's so powerful.

By irreducibly complex I mean a single system composed of several well-matched, interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning.
