“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 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.”
“A blind man's world is bounded by the limits of his touch; an ignorant man's world by the limits of his knowledge: a great man's world by the limits of his vision.”
“Wisdom is not the understanding of mystery. Wisdom is accepting that mystery is beyond understanding. That's what makes it mystery.”
“Every man is a damn fool for at least five minutes every day; wisdom consists in not exceeding the limit.”
“When a wise man does not understand, he says: "I do not understand." The fool and the uncultured are ashamed of their ignorance. They remain silent when a question could bring them wisdom.”
