“…those who have their mouths open all the time generally have their ears shut.”

“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.”

“Shut your mouth; open your eyes and ears. Take in what is there and give no thought to what might have been there or what is somewhere else. That can come later, if it must come at all. (And notice here how the true training for anything whatever that is good always prefigures and, if submitted to, will always help us in, the true training for the Christian life)”

“The object of opening the mind, as of opening the mouth, is to shut it again on something solid.”

“All say, ‘how hard it is that we have to die’ -- a strange complaint to come from the mouths of those who have had to live.”

“It's better to keep your mouth shut and appear stupid than open it and remove all doubt”
