<P> Kairos is also very important in Aristotle's scheme of rhetoric . Kairos is, for Aristotle, the time and space context in which the proof will be delivered . Kairos stands alongside other contextual elements of rhetoric: The Audience, which is the psychological and emotional makeup of those who will receive the proof; and To Prepon, which is the style with which the orator clothes the proof . </P> <P> In Ancient Greece, "kairos" was utilized by both of the two main schools of thought in the field of rhetoric . The competing schools were that of the Sophists, and that of their opposition, led by individuals such as Aristotle and Plato . Sophism approached rhetoric as an art form . Members of the school would travel around Greece teaching citizens about the art of rhetoric and successful discourse . In his article "Toward a Sophistic Definition of Rhetoric", John Poulakos defines rhetoric from a Sophistic perspective as follows: "Rhetoric is the art which seeks to capture in opportune moments that which is appropriate and attempts to suggest that which is possible ." Aristotle and Plato, on the other hand, viewed Sophistic rhetoric as a tool used to manipulate others, and criticized those who taught it . </P> <P> Kairos fits into the Sophistic scheme of rhetoric in conjunction with the ideas of prepon and dynaton . These two terms combined with kairos are their keys to successful rhetoric . As stated by Poulakos, Prepon deals with the notion that "what is said must conform to both audience and occasion ." Dynaton has to do with the idea of the possible, or what the speaker is attempting to convince the audience of . Kairos in the Sophistic context is based on the thought that speech must happen at a certain time in order for it to be most effective . If rhetoric is to be meaningful and successful, it must be presented at the right moment, or else it will not have the same impact on the members of the audience . </P> <P> Aristotle and his followers also discuss the importance of kairos in their teachings . In his Rhetoric, one of the ways that Aristotle uses the idea of kairos is in reference to the specificity of each rhetorical situation . Aristotle believed that each rhetorical situation was different, and therefore different rhetorical devices needed to be applied at that point in time . One of the most well known parts of Aristotle's Rhetoric is when he discusses the roles of pathos, ethos, and logos . Aristotle ties kairos to these concepts, claiming that there are times in each rhetorical situation when one needs to be utilized over the others . </P>
