When your worldview is built on a foundation of ignorance, there is no greater threat than critical thinking skills. I think most believers, if they took the time to think honestly about this, know it to be true. They often get so close, but fail to take the final step. They can recognize the danger of reasonable, critical thought, but choose to avoid thinking rather than question their foundation.
I came across a beautiful example of this in the latest Westwind (Walla Walla Univeristy's alumni journal). In Ginger Ketting-Weller's (vice president for academic administration) interview with Dan Lamberton she asks this question:
I'm not ready to get into Professor Lamberton's responce. It is a bit better than the question, but still unsatisfying. He at least admits that core tenets such as the virgin birth are unbelievable, but then seemingly retreats behind an amorphous shield of the sense of wonder this produces.
For me it is the question itself is what is interesting. Intelletually fulfulling belief is not something to be valued. The implied goal of this educational institution is to shelter students - to strengthen indoctrination. This creates a house divided. It is impossible to provide real education and shelter ignorance. Reason is dangerous to cherished delusions.
