Hi Chuck. Welcome to EvC.
Definitions taken from Webster's
Faith = firm belief in something for which there is no proof
Knowledge = the circumstance or condition of apprehending truth or fact through reasoning
What 'holes in your understanding of origins (bangers and toe) have you had to accept by faith?
For the rational mind, if there is a gap in knowledge then it remains a gap until it can be filled in by facts that can be shown to be true.
Take the idea of the Higgs Boson for example. Prof. Higgs et al took information that they knew to be true and then theorized the existence of the particle. Armed with this theory they went looking for it. You might say that they had 'faith' in it's existence but they did not have knowledge of it's existence until they actually found it. Had they not found it they would have been forced to go back and find out why their theory was wrong. What they would not do is to insist that their theory was correct in spite of the evidence.
The rational mind is willing to accept new information and adjust it's understanding accordingly. The faith based mind seeks to interpret new information in such a way that it does not conflict with previously held beliefs. So I think that your premise is faulty and that the rational mind recognizes a gap in understanding as a gap in understanding.
You now that us creationists really loved Jurassic park. Dinosaurs and man living in harmony. =)
As I recall, there wasn't actually a lot of harmony going on there or are you being sarcastic?
