13 Author’s Purpose
Purposes
Authors and audiences both have a wide range of purposes for communicating. The importance of purpose in rhetorical situations cannot be overstated. It is the varied purposes of a rhetorical situation that determine how an author communicates a text and how audiences receive a text. Rhetorical situations rarely have only one purpose. Authors and audiences tend to bring their own purposes (and often multiple purposes each) to a rhetorical situation, and these purposes may conflict or complement each other depending on the efforts of both authors and audiences.
UTHORS’ PURPOSES
In the textbook Writing Today, Johnson-Sheehan and Paine discuss purpose more specifically in terms of the author of a text. They suggest that most texts written in college or in the workplace often fill one of two broader purposes: to be informative or to be persuasive. Under each of these two broad purposes, they identify a host of more specific purposes. The following table is not exhaustive; authors could easily have purposes that are not listed on this table.
