What is Rhetoric?

There are many different ways to define rhetoric. Some may say it is the art of persuasion. Logos, ethos and pathos are three different ways to control rhetoric to persuade. When talking about persuasion you bring into question what is the difference between that and argumentative. It may also be seen as manipulative. The purpose of using rhetoric is to persuade an audience to their side. Persuasion is more of a single minded goal whereas an argument is making an assertion and then backing it up with evidence. An example of persuasion could be a salesmen trying to sell you on something based on it being a good deal or something such as a car. Some may say this is manipulation but the fact is that it wasn't harmful. These devices may be biased but these are useful tools used in everyday society.
