Until I can finish thinking through my real post for the day, here are some quotes to chew on:
"The object of opening the mind, as of opening the mouth, is to shut it again on something solid."
-- G. K. Chesterton
"A mind genuinely open with respect to everything would, like a box with no sides, prove in the final analysis to be empty, quite incapable of containing anything, even doubts."
-- Trevor A. Hart
