The Five Canons of Rhetoric
Aristotle and other Greek rhetoricians thought of rhetoric as having five canons or established principles. These principles outline the systems of classical rhetoric. I have listed the name of each canon, but I have defined each briefly in terms of a verb, i.e. what it is that these canons are supposed to help you do.
