I love G.K. Chesterton. N.T. Wright referred to him on a video I was watching today when being open minded came up. I searched for the direct quote and found this:

Merely having an open mind is nothing; the object of opening the mind, as of opening the mouth, is to shut it again on something solid.
G.K. Chesterton

Skepticism is a valid intermediary position.  One should be willing to examine evidence, and suspend judgement barring sufficient information.  However, sufficient is the key word here.  If you spend your entire life waiting to be entirely convinced of everything you will get nowhere.  That is the trouble with walking around open-minded; your brains tend to fall out.*

*I realize that last sentence is not original, but I can’t find out who originally said it.
