More learned than the ears.”

“The wrong sow by th' eare.”

“Nothing is more frightful than to see ignorance in action.”

“He was listening, too, for it is through the eyes and ears that one learns. A spiderweb of facts can tie up the lion of action; not to know is bad; not to strive to know is worse.”

“A learned fool is more foolish than an ignorant one.”

“Actions o' th' last age are like almanacks o' th' last year.”

“Action is eloquence.”

“Men trust their ears less than their eyes.”

“Of course, however, the living voice and the intimacy of a common life will help you more than the written word. You must go to the scene of action, first, because men put more faith in their eyes than in their ears, and second, because the way is long if one follows precepts, but short and helpful, if one follows patterns.”
