Carson's goal in closing the final paragraph with someone else's comments was to emphasize credibility. He did this by showing that the comments made by the speaker after his own had some similarity to those made by Dr. Martin Luther King, Jr. in his "I Have a Dream" speech. In addition, Carson used parallel structure to connect the two speeches stylistically. In conclusion, Carson wanted readers to believe that Dr. King would have spoken similarly if not identically to what he said in his "I Have a Dream" speech. This connection helps readers understand why Dr. King said the things he said and provides further evidence of Carson's skill as a writer.
