9.5 The Rhetorical Triangle: Ethos, Pathos, and Logos

Thousands of years ago, Aristotle provided us with three ways to appeal to an audience, and they’re called logos, pathos, and ethos. You’ll learn more about each appeal in the discussion below, but the relationship between these three appeals is also often called the rhetorical triangle as shown in Figure 9.5.1. The idea is a persuasive message has all 3 of the points of a triangle. (As you can see, this is a very triangle-heavy chapter).

Figure 9.5.1 The rhetorical triangle. Starting at the top of the triangle, ethos, which is ethics and credibility; then, going counterclockwise pathos, which is emotion; and logos, which is logic and reason, are the three points in the rhetorical triangle.


Latin for emotion, pathos is the fastest way to get your audience’s attention. People tend to have emotional responses before their brains kick in and tell them to knock it off. Be careful, though. Too much pathos can make your audience feel emotionally manipulated or angry because they’re also looking for the facts to support whatever emotional claims you make so they know they can trust you.


Latin for logic, logos is where those facts come in. Your audience will question the validity of your claims; the opinions you share in your writing need to be supported using science, statistics, expert perspective, and other types of logic. However, if you only rely on logos, your writing might become dry and boring, so even this should be balanced with other appeals.


Latin for ethics, ethos is what you do to prove to your audience that you can be trusted that you are a credible source of information. (See logos.) It’s also what you do to assure them that they are good people who want to do the right thing. This is especially important when writing an argument to an audience who disagrees with you. It’s much easier to encourage a disagreeable audience to listen to your point of view if you have convinced them that you respect their opinion and that you have established credibility through the use of logos and pathos, which show that you know the topic on an intellectual and personal level.

You can also gain ethos through your use of sources. Reliable, appropriate sources act as expert voices that provide a perspective you don’t have. Layout, graphic design choices, white space, style and tone: all of these factors influence your ethos.


Regardless of what appeals you use in your writing, it is important to be aware of fallacies (errors in reasoning) because they can reduce the impact of your message on your reader.
