Anyone else notice that the logo to this forum says "Creation Versus Evolution" (CVE) but the forum is named EVC?
You ever notice that in movie posters like this one:
They list the actors in reverse order as their pictures appear? It's to avoid complaints about who's getting the top billing. I imagine it's Percy's intent to give both evolutionism and creationism the same coutesy.
That is what exactly what makes murder mysteries so appealing... you presuppose the Butler did it all through the movie until you get that last piece of evidence that overturns every fact you were so confident in when you applied that evidence to the Butler.
The problem with the Presuppositionalist argument is that it assumes that all preconceptions and interpretations are equal. They're not, of course.
For instance creationists complain about how it's the materialist viewpoint that dominates our science classes and culture, but they forget that their viewpoint dominated western thought for almost 1,300 years after Christ.
What do we call that period? The Dark Ages. In the years after, when we've subsitituted the set of "preconceptions" represented by materialism, we've accomplished so much: from the realization of universal gravitation, to the re-emergence of theatre, to the development of medicine, communications and the internet, and even putting a man on the moon.
Clearly one of those "preconceptions" is superior to the other. I'll stake my money on methodological naturalism any day of the week, including Sunday. Reject the scientific process if you like, but shouldn't you sell your computer and move to a cave at that point?
