In GSA Today, geologist David Montgomery has published a splendid article (open pdf) on “The Evolution of Creationism.” It’s a useful primer for those who don’t have the time or inclination to read Ronald Number’s classic The Creationists: From Scientific Creationism to Intelligent Design, which treats the same topic in greater scope and detail. These should be required reading for both casual and strident creationists. The former might just change their minds, whereas the latter may get some sense for how ridiculous they are.
These two kinds of creationists are quite different. I will engage with casual creationists because they are willing to listen and learn. I simply ignore strident creationists. Their minds will never be changed and there is nothing to be gained by engaging them. Their stridency, obstinacy, and desperation strikes me as a peculiar (and pathetic) kind of weakness.
