Depend on who you're trying to persuade. Depending on the subject, the audience may be different, so the need for persuasion may have a different appeal. If it's a tragic novel, it may call for emotional and ethical persuasion. In a murder mystery, for example, it may call for logical and rational persuasion. In a fiction novel, it may call for facts and evidence, especially if evidence is needed to be cited. And most often times, persuasion includes interests and opinions, so don't worry about that one.

ROB
