I'm beginning to think that there are some ideas that serve as locks in the mind. Once installed, as long as the thinker throws away the key and/or refuses to open the mechanism to further scrutiny, that mind is hermeneutically sealed. That seems to be the goal of Fundamentalist indoctrination.
The idea of inerrancy appears to be one of the strongest deadbolts of the cognitive. It seems to be perfectly designed to put an end to the quest for deeper insights and broader understandings of scripture. As I said in a sermon years ago:
To say the Bible is 'inerrant' is to put an end to questioning. It is the conclusion of one brand of human logic. It is the answer to the only question a fundamentalist knows to ask. Once this conclusion is drawn, inquiry is ended and nothing further needs to be discovered, discussed or explained. For those who put faith in this brand of logic, 'inerrancy' is an 'exhaustive' summary of the Bible's truth and meaning.
