Aristotle's influence on modern culture has become more and more important in recent years. His contribution to the sum of all wisdom dominates all our philosophy and even provides direction for much of our science. And all effective debaters, whether they kw it or t, employ Aristotle's three basic principles of effective argument, which form the spine of rhetoric: ethos, the impact of the speaker's character upon the audience; pathos, the arousing of the emotions; and logos, the advancement of pertinent arguments. In his discussion, Aristotle observes several aspects of epic poetry, lyric poetry, and comedy. He maintains that poetry has greater philosophical value because it deals with universals, while history states particular facts.
