A rhetorical device is a tool an author uses to persuade his reader to think or act in a certain manner. We persuade people through the uses of ethos (ethical appeal), logos (logical appeal) and pathos (emotional appeal). Within this framework, rhetorical devices are used to convey and or all of the appeals. For example, Dr.King's use of repetition is purposeful in his "Dream" speech. He creates a rhythm and pattern that is not only easy to listen to but easy to remember. His speech opens with an analogy of how the promise for equality in the U.S. was like a bounced check. This creates a image for the listener to "see" the injustice of the problem.
