Obama gave a powerful and presidential speech that had many of the elements we look for in a successful and engaging presentation.
To conclude Obama wants to make his speech understood and he wants to get his message across by using many stylistic devices and examples where he always refers to the American Dream. He had greatest way to put all the rhetorical words in his speech.
The "two-ness" of the texture, to use DuBois's useful term.
He spoke about the Major issues facing the U. Fair or not, this perception has produced a hope that our next president will be a more powerful communicator, a Kennedy or Reagan, perhaps, who can use language less as a way to signal ideology and more as a means to bring the disparate parts of the nation together.
It is interesting to note that he was able to commend his competitors before his supporters. Praising the defeated, not ignoring or trampling on him. We can observe from his famous speech how does he using words, voice intonation, pronunciation, and body language to build the communication with his audience.
Back to Obama: "This was one of the tasks we set forth at the beginning of this campaign — to continue the long march of those who came before us, a march for a more just, more equal, more free, more caring and more prosperous America.
On the choice of words, he used understandable and simple language. There is no mention of DuBois or two-ness, but it is all there in the texture. It is a peculiar sensation, this double-consciousness, this sense of always looking at one's self through the eyes of others, of measuring one's soul by the tape of a world that looks on in amused contempt and pity.
