The Rhetoric Garage: Callin’ Out Cousin Pookie: Clinton and Obama’s Rhetoric at Selma

The pentad: scene in both speeches. "... it’s obvious that scene plays a major role in both speeches. They are giving speeches in Selma about an event that happened there. Their audience includes people who actually participated in this event. They speak in African American churches that evoke the genesis of the Civil Rights movement. When speakers are commemorating an event at or near the site of that event, it’s a safe bet that “scene” is going to be one of the central terms.

So, the next question is what is the other half of this central ratio of terms in each speech?

I suggest that Clinton and Obama’s speeches pair “scene” up with two different terms, and for understandable reasons. These choices shape the very different speeches they give.

In Clinton’s case, her speech centers on the purpose/scene ratio (with “purpose” being the dominant term). Obama’s speech centers on the act/scene ratio (with “act” being the dominant term)".
