Message
The What.
The message of a rhetorical piece is the What—the actual content of the piece. As in what the words say, and what they’re about.
Students often confuse the Message with the Purpose. Just remember that MESSAGE = WHAT. The Purpose has to do with the Why—the opinion rhetor wants to audience to have, or the action she wants it to take. Put it this way: PURPOSE = WHY.
Civility isn’t the end of deliberative argument; it’s just the beginning. To get anyone even to listen to you, you have to make your audience believe you’re worth listening to.
