That´s mere rhetoric! Rhetoric, which always occurs in discourses where questions of ethics is important, has since ancient times been accused of being an immoral and a value-neutral art that seduces people with flattery and what they want to hear with no interest in presenting the truth to the audience. Plato's condemnation of this practice was tough and Plato's works Gorgias and Faidros have since represented the relationship between rhetoric and philosophy; rhetoric that is described as the semblance of an art [pseudos] while philosophy stands as the search for truth. In my work I want to present the relationship between rhetoric and ethics by reading Charlotte Jørgensen and Barbara Cassin interpretations of Chaïm Perelman and Lucie Olbrecht-Tyteca, and examine the consequences of this approach may have for rhetorical criticism.
