Rhetoric

There are three different parts of rhetoric: Ethos, Pathos and Logos.
Ethos is part of Rhetoric that has to do with our personality, I or We. In writing we use ethos when we want to convince people of our credibility.
Pathos is described as a persuasive technique that appeals to our emotions. We use pathos to express our emotion and persuade people that we really care about their emotions as well.
Logos is described as a technique in writing that appeals to our intellect, it is very factual type of persuasion and depends on our knowledge of subject.
We use all three of those parts of rhetoric in every part of our communication. They can be used separately, but in most cases they are used interchangeably throughout our communications. They are all tightly interconnected and are most effective when used together.
