Aristotle’s main focus is attention to the systematic study of art. This came as a response to Plato’s criticism. They both agreed about the Sophist not showing a true techne of Rhetoric. Aristotle defined Rheortic into three books.

First, defines the domain of rhetoric. Second, discusses proof derived from character and emotion, and third shows the style and arrangement.  Aristotle says rhetoric is the counterpart of dialectic, which means involves reasoning from commonly held opinions.

The difference between the Sophists and Aristotle is that the Sophists taught their students to memorize speeches, and Aristotle taught his students to investigate the means of persuasion. This is because he points out that no art achieves its goals in every case. Further explaining Aristotles ideas that rhetoric is an art that can be studied systematically.
