Before we can understand the ways in which the rhetorical appeals work, we must first understand what rhetoric is.
There are many commonly-used definitions, but for our purposes "rhetoric" refers to all of the following:
In the work we'll do in our rhetorical analysis, there are 2 parties to be concerned with:
We will consider ourselves to be a 3rd party: the observer. We're not being persuaded. We're not persuading. We're just observing the interaction between the rhetor and the audience.
Who is the rhetorin this situation? It's the Starbucks employee, because that's the person trying to persuade someone.
Who is the audience? It's the woman in the car, because she's the person the rhetor is trying to persuade.
What is the act of persuasiontaking place? The Starbucks employee is attempting to persuade the woman to buy a muffin and a pricey coffee drink.
An observer--such as yourself--would consider the rhetor, the audience, and the rhetoric that is being used by the rhetor in an attempt to persuade the audience.
The observer would analyze the rhetoric--in this case, using the framework of the three rhetorical appeals (explained below), and then
explain their analysis in an essay that answers this question: "Has the rhetor made effective use of rhetoric in trying to persuade the audience? (Why or why not?)?"
"Of the [modes of persuasion] provided through speech there are three species: for some are in the character of the speaker, and some are in disposing the listener in some way, and some in the argument itself, by showing or seeming to show something" --Aristotle, On Rhetoric, 1356b (trans. George A. Kennedy)
In other words, Aristotle argues that there are three elements to the art of persuasion:
We call these three elements rhetorical appeals. It's not necessary for every act of persuasion to make use of all three appeals. Often, however, there is some element of each. In academic writing, ethos and logos are given more respect than pathos. An essay that relies primarily on pathos, with little use of ethos or logos, is unlikely to be perceived by an academic audience as persuasive.
Below, each of these appeals is explained in more detail.
The use of ethos is called an "ethical appeal." Note that this is very different from our usual understanding of the word "ethical." "Ethos" is used to describe the audience's perception of the rhetor's credibility or authority. The audience asks themselves, "What does this person know about this topic?" and "Why should I trust this person?" There are two kinds of ethos:
When we discuss the ethos of the rhetor, we decide whether it is strong or weak. We might use a phrase like, "His extrinsic ethos is strong because…" or "His intrinsic ethos is strong, but his extrinsic ethos is weak…"
Extrinsic: the character, expertise, education, and experience of the rhetor
Intrinsic ethos: how the rhetor writes or speaks
First, you should always remember that when you are engaged in rhetorical analysis, it's not your job to decide if youperceive the rhetor as credible or authoritative. Instead, you must evaluate how the audienceis likely to perceive the rhetor.
Second, do not confuse the strategy of "Testimony and Authority" (see below, under "Logos") with ethos. When a rhetor uses information from someone else as a source to support their argument, that's an example of logos: it's the strategy of "Testimony and Authority."
Students sometimes confuse the two because in both cases, the credibility and authority of the person speaking (or writing) is important. However, there's an important difference:
When the rhetor is known by the audience to be experienced and an expert on the topic, that's an example of ethos, because their extrinsic ethos is strong.
When the rhetor cites someone else who is experienced and an expert, that's an example of logos, because the rhetor is using the strategy of testimony and authority.
The use of pathos is called a "pathetic appeal." Note that this is very different from our usual understanding of the word "pathetic." "Pathos" is used to describe the rhetor's attempt to appeal to "an audience's sense of identity, their self-interest, and their emotions."
"Pathos" most often refers to an attempt to engage an audience's emotions. Think about the different emotions people are capable of feeling: they include love, pity, sorrow, affection, anger, fear, greed, lust, and hatred. If a rhetor tries to make an audience feel emotions in response to what is being said or written, then they are using pathos.
"Love" will be felt if the audience can be made to believe in their fundamental connections to other human beings.
"Pity" will be felt if the plight of the homeless hurricane victim can be made very vivid to the audience.
"Fear" will be felt if the audience can be made to imagine what they would feel like in that homeless victim's place.
"Anger" will be felt if the audience realizes how little has been done by those who are responsible for helping.
The use of logos is called a "logical appeal." A statement does not have to be considered logical to be a logical appeal. As an observer, you can recognize that the rhetor is attempting to use logos to persuade the audience, but that recognition doesn't mean the rhetor is succeeding. We use the term logos to describe what kind of rhetorical appeal is being made, not to evaluate whether or not an appeal makes sense to us (as observers) or to the audience being addressed. "Logos" is the use of the strategies of logic to persuade your audience. If an statement attempts to persuade the audience by making a reasonable claim and offering proof in support of that claim (rather than by trying to make them feel certain emotions, or by making them perceive the speaker as credible), then that statement is a logical argument.
There are many ways of making logical arguments. Here are a few common strategies:
Cause or consequence
A claim about one thing causing another, or one thing being caused by another.
"Global warming is caused by greenhouse gases being produced by humankind."
"The current economic crisis was caused primarily by deregulation of the financial industry."
"If the government gets involved in providing health insurance to the American people, we will see a sharp decline in the quality of our medical care."
Analogy
A claim about the qualities of one thing using a comparison about another thing.
"The ozone layer of the atmosphere is like the outer layer of skin on the human body, and if it goes away, planet Earth will be in a lot of pain."
"Going to that class is about as exciting as watching paint dry."
"George Bush taking credit for the Berlin Wall coming down is like the rooster taking credit for the sunrise." (Al Gore, 1992 Vice Presidential Debate)
"That candidate is what we call a post turtle. Imagine you're driving along a country road and you see a turtle up on top of a fence post. He doesn't know how he got there. He doesn't know what he's doing there. And he has no idea what to do next." (See this entry at Snopes.com)
Testimony and authority
A claim that involves citing the opinion of someone other than the rhetor, someone respected by the audience.
"4 out of 5 Dentists surveyed would recommend sugarless gum to their patients who chew gum" (Trident Gum advertisement).
"The leading U.S. military commanders in Iraq say the surge strategy is working."
"How bad is the current financial mess? According to Alan Greenspan, U.S. Federal Reserve Chairman, it's 'the type of wrenching financial crisis that comes along only once in a century.'" ("Greenspan").
Definition
A claim about the meaning or nature of something.
"The president is a socialist."
"Marriage is a union between a man and a woman."
"Last year's Super Bowl game was extremely boring."
Syllogism
A claim using deductive logic involving a major premise, a minor premise, and conclusion. This is a move from the general to the specific.
"Nuclear power plants generate dangerous nuclear waste, and the new power plant they're planning to build in our community is a nuclear power plant. So the new power plant will be dangerous."
"Republicans favor deregulation. John McCain is a Republican, so he will pursue a policy of deregulation if elected."
"Democrats like to 'tax and spend.' Barack Obama is a Democrat, so he's going to raise our taxes if elected."
Support a generalization with examples
A claim using inductive logic, where a general statement about something is backed up by specific examples.
In the second presidential debate of 2008, Senator John McCain emphasized his own good judgment in this way: "And I am convinced that my record, going back to my opposition from sending the Marines to Lebanon, to supporting our efforts in Kosovo and Bosnia and the first Gulf War, and my judgment, I think, is something that ... I'm willing to stand on."
Also in the second presidential debate of 2008, Senator Barack Obama argued that the United States should maintain good relations with other nations in order to make the best use of our own military resources in a time of economic constraint. He then illustrated his general statement with this specific example: "Let's take the example of Darfur just for a moment. Right now there's a peacekeeping force that has been set up and we have African Union troops in Darfur to stop a genocide that has killed hundreds of thousands of people. We could be providing logistical support, setting up a no-fly zone at relatively little cost to us, but we can only do it if we can help mobilize the international community and lead."
Seldom is any one statement an example of only one appeal.
This statement combines all three appeals:
Let's review what we covered above: Rhetoric is defined for our purposes as
In the work we'll do in our rhetorical analysis, there are 2 parties to be concerned with:
We will consider ourselves to be a 3rd party: The observer. We're not being persuaded. We're not persuading. We're just observing the interaction between the rhetor and the audience. The rhetorical appeals are the three elements to the art of persuasion as defined by Aristotle
