During the last five decades, rhetoricians have been deeply divided over whether rhetoric can be effectively used in teaching composition. Some have argued that rhetoric involves some or all forms of persuasion. Others believe that it is the arguer's manipulation of the audience. These two views, among others, point to the fact that they are, in principle, incompatible to the extent where rhetoricians will never meet. Because of these different views, rhetoricians are in a state of flux as to what strategies or principles should be used when teaching rhetoric and composition.
