It is necessary to understand the use of persuasive language in writings. Persuasive language is used by some writers to call the readers' attention, to make them think or behave in a particular way.
"Walking with the Wind: A Memoir of the Movement" is a novel written in 1998 by John Lewis with Mike D'Orso and it tells one of the most important records of the American Civil Rights movement. In this excerpt, John Lewis, the main character, is giving a speech, sending the message that Civil rights advocates cannot expect the federal government to promote justice.
In this speech, Lewis is presenting all the facts about how government disregards the Civil rights in order to support his ideas. At the end he tries to persuade his audience by saying "The revolution is at hand, and we must free ourselves of the chains of political and economic slavery." By saying such phrase he is trying to make the audience think and take action. He wants them to take part in the revolution and stand up for themselves. He, therefore, is persuading them to do what is best for them and to protect the Civil Rights.
