The loud proclaim they through the town declare.”

Context: I have no technical advice or counsel to offer those of you who labor in this vineyard, the one that produces words and pictures. You will, I am sure, forgive me for not telling you that instruments with which you work are miraculous, that your responsibility is unprecedented or that your aspirations are frequently frustrated. It is not necessary to remind you of the fact that your voice, amplified to the degree where it reaches from one end of the country to the other, does not confer upon you greater wisdom than when your voice reached only from one end of the bar to the other. All of these things you know.
