“Any fool can see the limits of seeing, but not even the wisest know the limits of knowing. Thus is ignorance rendered invisible, and are all Men made fools.”
“There are genuine mysteries in the world that mark the limits of human knowing and thinking. Wisdom is fortified, not destroyed, by understanding its limitations. Ignorance does not make a fool as surely as self-deception.”
“Any fool can turn a blind eye but who knows what the ostrich sees in the sand.”
“Wisdom is the right use of knowledge. To know is not to be wise. Many men know a great deal, and are all the greater fools for it. There is no fool so great a fool as a knowing fool. But to know how to use knowledge is to have wisdom.”
“We all know a fool when we see one - but not when we are one.”
“Passion often makes fools of the wisest men and gives the silliest wisdom.”
