How does Martin Luther King powerful speech bring out the aspirations of the blacks in the U.S?

In his I
Have a Dream speech, Dr. Martin Luther King, Jr. very eloquently outlines the desires and
aspirations of African Americans. Very soon after beginning to speak, he notes that it has been
100 years since the signing of the Emancipation Proclamation; yet, the Negro is still not
free. Of course, in the 100 years since gaining legal freedom, African Americans were still
hungry for actual freedom. Shortly thereafter, King metaphorically suggests that African
Americans intended to cash a check, written by the countrys founders. In those founding
documents, equality was championed and every person was said to be entitled to the life, liberty
and the pursuit of happiness. In denying African Americans those privileges, King suggested that
America was attempting to pass a worthless check. As he articulately progresses to the
repetition of the words, I have a dream, he specifically notes the desire for equality,
brotherhood, and freedom and justice. He also mentions the sincere desire for a time when
they (African Americans) will not be judged by the color of their skin but by the content of
their character.
