Scholars have discussed the different interpretations of Aristotle's views of rhetoric and his philosophy. Some believe that Aristotle may not have even been the inventor of his famous persuasion methods. In the second chapter of "Rhetoric", Aristotle's view on pathos changes from the use in discourse to the understanding of emotions and their effects. William Fortenbaugh pointed out that for the Sophist Gorgias, "Being overcome with emotion is analogous to rape." Aristotle opposed this view and created a systematic approach to pathos. Fortenbaugh argues that Aristotle's systematic approach to emotional appeals "depends upon correctly understanding the nature of individual emotions, upon knowing the conditions favorable to, the objects of, and the grounds for individual emotions".
