This whole article on Barack’s oratorical techniques is worth a read. Another hat tip to Arts and Letters Daily.
One of the best known of Cicero’s techniques is his use of series of three to emphasise points: the tricolon. (The most enduring example of a Latin tricolon is not Cicero’s, but Caesar’s “Veni, vidi, vici” – I came, I saw, I conquered.) Obama uses tricola freely. Here’s an example: “Tonight, we gather to affirm the greatness of our nation, not because of the height of our skyscrapers, or the power of our military, or the size of our economy …” In this passage, from the 2004 Democratic convention speech, Obama is also using the technique of “praeteritio” – drawing attention to a subject by not discussing it. (He is discounting the height of America’s skyscrapers etc, but in so doing reminds us of their importance.)
One of my favourites among Obama’s tricks was his use of the phrase “a young preacher from Georgia”, when accepting the Democratic nomination this August; he did not name Martin Luther King. The term for the technique is “antonomasia”. One example from Cicero is the way he refers to Phoenix, Achilles’ mentor in the Iliad, as “senior magister” – “the aged teacher”. In both cases, it sets up an intimacy between speaker and audience, the flattering idea that we all know what we are talking about without need for further exposition. It humanises the character – King was just an ordinary young man, once. Referring to Georgia by name localises the reference – Obama likes to use the specifics to American place to ground the winged sweep of his rhetoric – just as in his November 4 speech: “Our campaign … began in the backyards of Des Moines and the living rooms of Concord and the front porches of Charleston”, which, of course, is also another tricolon.
