Well done, Percy! PaulK was right - Stansfield was being misquoted. It's even more telling that Stansfield was doing what the creationists absolutely insist upon: presenting the "problems" with scientific theory (in this case various dating methods) in a textbook. Of course, he then goes on to explain a) why a particular method ISN'T used, and b) what methods ARE used to give accurate dates.
Not bad. The creationists quote mining Stansfield are hoist by their own petard. What a surprise.
