Barry Goldwater (b. 1909), U.S. Republican politician. Speech, July 16, 1964, accepting presidential nomination, Republican National Convention, San Francisco. Quoted in New York Times (July 17, 1964).
Goldwater later attributed these words to Cicero. On Oct. 31, 1964, the Democratic contender for the presidency, Lyndon B. Johnson, replied in a speech in New York: "Extremism is an unpardonable vice. Moderation in the affairs of the nation is the highest virtue." Johnson won a sweeping victory against Goldwater in the presidential election three days later.
