Please read the following sentences, and think about the message(s) each one is giving you. Imagine that you don't know anything about the person who is making the statements other than what you read. Treat each example separately.
Each of these statements exhibits an attempt to convince you that solar panels are a good idea, but each in a different way. Think about the language devices employed in each of the sentences. What part of your psyche does it attempt to address? Is it logic, emotion, or something else? Are they obvious attempts to gain your agreement, or do they seem reasonable?
Each of these sentences uses a different rhetorical strategy. Rhetorical strategies are the subject of this lesson, specifically the rhetorical triangle. At the root of all of this is rhetoric, so let's start there. This is just a quick video introduction - no need to take any notes or anything like that.
Purdue University's Online Writing Lab [1] (OWL) provides a lot of publicly available resources that are designed to help students and others become better writers. They do not allow embedded videos, so please click on the link below if you'd like to watch.
Rhetoric/rhetorical arguments are designed to convince an audience of whatever the speaker is trying to say, or as Purdue OWL notes, it is "about using language in the most effective way." You most often hear this when referring to a politician, or at least someone acting politically or disingenuously, for example: "That speech was all rhetoric." When you hear or read this phrase, it is meant in a negative way and implies that the speaker was using language to trick the audience into believing the argument they were presenting. As noted in the video above, this negative connotation goes back centuries. But rhetoric has a few connotations, not all of them negative. It can refer to "the art of speaking or writing effectively," and "the study of writing or speaking as a means of communication or persuasion." These two definitions do not necessarily connote deceit. But it can also mean "insincere or grandiloquent language" (Credit: Merriam-Webster [3]).
So, contrary to popular belief, rhetorical arguments are not always "insincere." That said, in this course, we are most concerned about seeing through rhetoric (rhetoric in the negative sense, that is) to evaluate arguments. Please note that rhetorical strategies can also be deployed visually - for example in images, photos, and video - and audibly. Advertisers do this all the time.
Rhetoric is used to persuade people, and there are three general strategies used to do this: ethos, pathos, and logos. Please watch the video as an introduction to these strategies. We will then go into more detail in each in the following lessons.
Purdue University has an excellent online writing lab. It has a lot of very helpful information, including how to use rhetorical strategies.
Ethos, pathos, and logos are rhetorical strategies, but these are not rhetorical devices. Rhetorical devices are specific methods that can be deployed to make a persuasive argument, whereas rhetorical strategies are general strategies. You have likely picked up on many of these devices when listening, reading, or speaking. Politicians are particularly fond of them. The "Mental Floss" website [6] goes over some of them. If you Google around, you will find more.
