Antoine Braet did a re-examination of Aristotle's text and in this he examined the speakers goal of the effect on the audience. Braet explains there are three perspectives of every emotion that a speaker is trying to arouse from the audience: the audiences condition, who the audience is feeling these emotions for and the motive. Moreover, Aristotle pointedly discusses pleasure and pain in relation to the reactions these two emotions cause in an audience member. According to Aristotle, emotions vary from person to person. Therefore, he stresses the importance of understanding specific social situations in order to successfully utilize pathos as a mode of persuasion. Aristotle identifies the introduction and the conclusion as the two most important places for an emotional appeal in any persuasive argument. 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". Modern philosophers were typically more skeptical of the use of emotions in communication, with political theorists such as John Locke hoping to extract emotion from reasoned communication entirely. George Campbell presents another view unlike the common systematic approach of Aristotle. Campbell explored whether appeals to emotion or passions would be "an unfair method of persuasion," identifying seven circumstances to judge emotions: probability, plausibility, importance, proximity in time, connection of place, relations to the persons concerned, and interest in the consequences. The 84 BC "Rhetorica ad Herennium" book of an unknown author theorizes that the conclusion is the most important place in a persuasive argument to consider emotions such as mercy or hatred, depending on the nature of the persuasion. The "appeal to pity", as it is classified in "Rhetorica ad Herennium", is a means to conclude by reiterating the major premise of the work and tying while incorporating an emotional sentiment. The author suggests ways in which to appeal to the pity of the audience: "We shall stir pity in our hearers by recalling vicissitudes of future; by comparing the prosperity we once enjoyed with our present adversity; by entreating those whose pity we seek to win, and by submitting ourselves to their mercy."
