The rhetoric theory was created by Aristotle, which is defined, “discovering all possible means of persuasion”. Aristotle said means are based on three types of persuasion. The three are logical, emotional and ethical proof. The logical proof comes from the line of argument, ethical proof is the way a speakers character is revealed and emotional is the feeling the listeners pick up from the speaker. Aristotle focused on three types of speaking which where forensic, epidetic and deliberative. The Forensic speaking purify decisions considering actions of the past the epidictic speaking consider praise and blame for present day audiences and the deliberative speaking attempts to influence those who consider future policy.
