Go back to Mississippi, go back to Alabama, go back to South Carolina, go back to Georgia, go back to Louisiana, go back to the slums and ghettos of our northern cities, knowing that somehow this situation can and will be changed. Let us not wallow in the valley of despair. (P303, line 19-22)
I have a dream that one day this nation will rise up and live out the true meaning of its creed: "We hold these truths to be self-evident; that all men are created equal." I have a dream that one day on the red hills of Georgia the sons of former slaves and the sons of former slave owners will be able to sit down together at the table of brotherhood. I have a dream that one day even the state of Mississippi, a state sweltering with the heat of injustice, sweltering with the heat of oppression, will be transformed into an oasis of freedom and justice. (P303, line 25-38)
"When will you be satisfied?" We can never be satisfied as long as the Negro is the victim of the unspeakable horrors of police brutality. We can never be satisfied as long as our bodies, heavy with the fatigue of travel, cannot gain lodging in the motels of the highways and the hotels of the cities. We cannot be satisfied as long as the Negro's basic mobility is from a smaller ghetto to a larger one. We can never be satisfied as long as our children are stripped of their selfhood and robbed of their dignity by signs stating "for whites only." We cannot be satisfied as long as a Negro in Mississippi cannot vote and a Negro in New York believes he has nothing for which to vote.No, no, we are not satisfied, and we will not be satisfied until justice rolls down like waters and righteousness like a mighty stream. ( P032, line 45, P303, line 1-11)
Dr. Martin Luther King used the rhetorical devices Polysyndeton here to convince people that the situation of unequal about human right, it will be change in more state and area. he convince people that the equal will be happen and everyone have to fight for it and do not give up hope.
Dr. king used the rhetorical device Anaphora here to show his emotion about the unequal of the right of human that all people deserved equal like The Declaration of Independence was said in July 4, 1776. But with him and more people like him it just dream.
Dr. King used the rhetorical device Hypophora here to give all people a question that do they think people can satisfy with the way they was treated. People cannot satisfy until they got their right equal, not " for white only". It was a cause and affect between what people receive and how much for their satisfy.
