Words can be especially persuasive, asking others to embrace a particular point of view. In addition, words can be effectively used rhythmically to evoke images, memories, or feelings.
There is a great variety of ways in which words can be artfully assembled for political purposes, such as speeches, testimony and slogans. In wartime, propaganda frequently uses language as a powerful weapon to create, separate, and destroy all kinds of people, places, and ideologies. At the other extreme, poetry takes us back to the center of who we are as human beings.
A slogan or quote may be a memorable motto, phrase or thought used in a political context as a repetitive expression of an idea or purpose. It varies from the written and the visual to those performed in chant or in music. Notable words can often serve more as social expression of unified purpose than as communication to an intended audience.
Perhaps, art can prevail over injustice most effectively by revealing the truth of who we are and why we must fight for our humanity.
