It is not necessary to remind you that the fact that your voice is amplified to the degree where it reaches from one end of the country to the other does not confer upon you greater wisdom or understanding than you possessed when your voice reached only from one end of the bar to the other.

Edward R. Murrow (1908-1965) American journalist

Speech, Radio and Television News Directors Association (RTNDA), Chicago (15 Oct 1958)

Full speech. Often quoted: "Just because your voice reaches halfway around the world doesn't mean you are wiser than when it reached only to the end of the bar."
