rhetorical devices in argumentative essays

What Is a Rhetorical Device? Definition, List, Examples

• An Introduction to Punctuation

• B.A., English, Rutgers University

A rhetorical device is a linguistic tool that employs a particular type of sentence structure, sound, or pattern of meaning in order to evoke a particular reaction from an audience. Each rhetorical device is a distinct tool that can be used to construct an argument or make an existing argument more compelling.  

Any time you try to inform, persuade , or argue with someone, you’re engaging in rhetoric. If you’ve ever had an emotional reaction to a speech or changed your mind about an issue after hearing a skilled debater's rebuttal, you've experienced the power of rhetoric. By developing a basic knowledge of rhetorical devices, you can improve your ability to process and convey information while also strengthening your persuasive skills. 

Types of Rhetorical Devices

There are four types of rhetorical devices:

• Logos. Devices in this category seek to convince and persuade via logic and reason. They will usually make use of statistics, cited facts, and statements by authorities to make their point and persuade the listener.
• Pathos. These rhetorical devices base their appeal in emotion. This could mean invoking sympathy or pity in the listener, or making the audience angry in the service of inspiring action or changing their mind about something.
• Ethos. Ethical appeals try to convince the audience that the speaker is a credible source, that their words have weight and must be taken seriously because they are serious and have the experience and judgment necessary to decide what’s right.
• Kairos. This is one of the most difficult concepts in rhetoric; devices in this category are dependent on the idea that the time has come for a particular idea or action. The very timeliness of the idea is part of the argument.

Strongest Rhetorical Devices

Since rhetoric dates back to ancient times, much of the terminology used to discuss it comes from the original Greek. Despite its ancient origins, however, rhetoric is as vital as ever. The following list contains some of the most important rhetorical devices to understand:

• Alliteration , a sonic device, is the repetition of the initial sound of each word (e.g. Alan the antelope ate asparagus).
• Cacophony , a sonic device, is the combination of consonant sounds to create a displeasing effect. 
• Onomatopoeia , a sonic device, refers to a word that emulates the real-life sound it signifies (e.g. using the word "bang" to signify an explosion).
• Humor  creates connection and identification with audience members, thus increasing the likelihood that they will agree with the speaker. Humor can also be used to deflate counter-arguments and make opposing points of view appear ridiculous.
• Anaphora  is the repetition of certain words or phrases at the beginning of sentences to increase the power of a sentiment. Perhaps the best-known example of anaphora is Martin Luther King Jr.'s repetition of the phrase "I have a dream."
• Meiosis is a type of euphemism that intentionally understates the size or importance of its subject. It can be used to dismiss or diminish a debate opponent's argument. 
• Hyperbole  is an exaggerated statement that conveys emotion and raises the bar for other speakers. Once you make a hyperbolic statement like “My idea is going to change the world," other speakers will have to respond in kind or their more measured words may seem dull and uninspiring in comparison.
• Apophasis  is the verbal strategy of bringing up a subject by denying that that very subject should be brought up at all.
• Anacoluthon  is a sudden swerve into a seemingly unrelated idea in the middle of a sentence. It can seem like a grammatical mistake if handled poorly, but it can also put powerful stress onto the idea being expressed.
• Chiasmus  is a technique wherein the speaker inverts the order of a phrase in order to create a pretty and powerful sentence. The best example comes from President John F. Kennedy's inaugural address: "Ask not what your country can do for you — ask what you can do for your country ."
• Anadiplosis  is the use of the same word at the end of one sentence and at the beginning of the subsequent sentence, forming a chain of thought that carries your audience to the point you’ve chosen.
• Dialogismus  refers to moments when the speaker imagines what someone else is thinking, or speaks in the voice of someone else, in order to explain and then subvert or undermine counterpoints to the original argument.
• Eutrepismus , one of the most common rhetorical devices, is simply the act of stating points in the form of a numbered list. Why is it useful? First off, this devices makes information seem official and authoritative. Second, it gives speech a sense of order and clarity. And third, it helps the listener keep track of the speaker's points.
• Hypophora   is the trick of posing a question and then immediately supplying the answer. Do you know why hypophora is useful? It's useful because it stimulates listener interest and creates a clear transition point in the speech.
• Expeditio  is the trick of listing a series of possibilities and then explaining why all but one of those possibilities are non-starters. This device makes it seem as though all choices have been considered, when in fact you've been steering your audience towards the one choice you desired all along.
• Antiphrasis  is another word for irony. Antiphrasis refers to a statement whose actual meaning is the opposite of the literal meaning of the words within it.
• Asterismos . Look, this is the technique of inserting a useless but attention-grabbing word in front of your sentence in order to grab the audience’s attention. It's useful if you think your listeners are getting a bit bored and restless.

Examples of Rhetorical Devices

How do you identify a rhetorical device? In fact, you hear them in daily life. Rhetoric isn’t just for debates and arguments; these devices are used in everyday speech, fiction and screenwriting, legal arguments, and more. Consider these famous examples and their impact on their audience.

• “ Fear leads to anger. Anger leads to hate. Hate leads to suffering.” – Star Wars: The Empire Strikes Back . Rhetorical Device : Anadiplosis . The pairs of words at the beginning and ending of each sentence give the impression that the logic invoked is unassailable and perfectly assembled.
• “ Ask not what your country can do for you, ask what you can do for your country.” —President John F. Kennedy. Rhetorical Device : Chiasmus . The inversion of the phrase can do and the word country creates a sense of balance in the sentence that reinforces the sense of correctness.
• "I will not make age an issue of this campaign. I am not going to exploit, for political purposes, my opponent’s youth and inexperience." –President Ronald Reagan Rhetorical Device : Apophasis . In this quip from a presidential debate, Reagan expresses mock reluctance to comment on his opponent's age, which ultimately does the job of raising the point of his opponent's age.  
• “ But in a larger sense, we cannot dedicate, we cannot consecrate, we cannot hallow this ground.” —Abraham Lincoln, Gettysburg Address . Rhetorical Device : Anaphora . Lincoln’s use of repetition gives his words a sense of rhythm that emphasizes his message. This is also an example of kairos : Lincoln senses that the public has a need to justify the slaughter of the Civil War, and thus decides to make this statement appealing to the higher purpose of abolishing slavery. 
• “ Ladies and gentlemen, I've been to Vietnam, Iraq, and Afghanistan, and I can say without hyperbole that this is a million times worse than all of them put together.” – The Simpsons . Rhetorical Device : Hyperbole . Here, hyperbole is used to humorous effect in order to undermine the superficial point of the sentence.
• Rhetoric. The discipline of discourse and persuasion via verbal argument.
• Rhetorical Device. A tool used in the course of rhetoric, employing specific sentence structure, sounds, and imagery to attain a desired response.
• Logos. The category of rhetorical devices that appeal to logic and reason. 
• Pathos. The category of rhetorical devices that appeal to emotions.
• Ethos.  The category of rhetorical devices that appeal to a sense of credibility. 
• Kairos.  The concept of “right place, right time” in rhetoric, wherein a specific rhetorical device becomes effective because of circumstances surrounding its use.

31 Useful Rhetorical Devices

What is a rhetorical device and why are they used.

As with all fields of serious and complicated human endeavor (that can be considered variously as an art, a science, a profession, or a hobby), there is a technical vocabulary associated with writing. Rhetoric is the name for the study of writing or speaking as a means of communication or persuasion, and though a writer doesn’t need to know the specific labels for certain writing techniques in order to use them effectively, it is sometimes helpful to have a handy taxonomy for the ways in which words and ideas are arranged. This can help to discuss and isolate ideas that might otherwise become abstract and confusing. As with the word rhetoric itself, many of these rhetorical devices come from Greek.

How to Write a Rhetorical Analysis | Key Concepts & Examples

Published on August 28, 2020 by Jack Caulfield . Revised on July 23, 2023.

A rhetorical analysis is a type of essay  that looks at a text in terms of rhetoric. This means it is less concerned with what the author is saying than with how they say it: their goals, techniques, and appeals to the audience.

Rhetoric, the art of effective speaking and writing, is a subject that trains you to look at texts, arguments and speeches in terms of how they are designed to persuade the audience. This section introduces a few of the key concepts of this field.

Appeals: Logos, ethos, pathos

Appeals are how the author convinces their audience. Three central appeals are discussed in rhetoric, established by the philosopher Aristotle and sometimes called the rhetorical triangle: logos, ethos, and pathos.

Logos , or the logical appeal, refers to the use of reasoned argument to persuade. This is the dominant approach in academic writing , where arguments are built up using reasoning and evidence.

Ethos , or the ethical appeal, involves the author presenting themselves as an authority on their subject. For example, someone making a moral argument might highlight their own morally admirable behavior; someone speaking about a technical subject might present themselves as an expert by mentioning their qualifications.

Pathos , or the pathetic appeal, evokes the audience’s emotions. This might involve speaking in a passionate way, employing vivid imagery, or trying to provoke anger, sympathy, or any other emotional response in the audience.

These three appeals are all treated as integral parts of rhetoric, and a given author may combine all three of them to convince their audience.

Text and context

In rhetoric, a text is not necessarily a piece of writing (though it may be this). A text is whatever piece of communication you are analyzing. This could be, for example, a speech, an advertisement, or a satirical image.

In these cases, your analysis would focus on more than just language—you might look at visual or sonic elements of the text too.

The context is everything surrounding the text: Who is the author (or speaker, designer, etc.)? Who is their (intended or actual) audience? When and where was the text produced, and for what purpose?

Looking at the context can help to inform your rhetorical analysis. For example, Martin Luther King, Jr.’s “I Have a Dream” speech has universal power, but the context of the civil rights movement is an important part of understanding why.

Claims, supports, and warrants

A piece of rhetoric is always making some sort of argument, whether it’s a very clearly defined and logical one (e.g. in a philosophy essay) or one that the reader has to infer (e.g. in a satirical article). These arguments are built up with claims, supports, and warrants.

A claim is the fact or idea the author wants to convince the reader of. An argument might center on a single claim, or be built up out of many. Claims are usually explicitly stated, but they may also just be implied in some kinds of text.

The author uses supports to back up each claim they make. These might range from hard evidence to emotional appeals—anything that is used to convince the reader to accept a claim.

The warrant is the logic or assumption that connects a support with a claim. Outside of quite formal argumentation, the warrant is often unstated—the author assumes their audience will understand the connection without it. But that doesn’t mean you can’t still explore the implicit warrant in these cases.

For example, look at the following statement:

We can see a claim and a support here, but the warrant is implicit. Here, the warrant is the assumption that more likeable candidates would have inspired greater turnout. We might be more or less convinced by the argument depending on whether we think this is a fair assumption.

Rhetorical analysis isn’t a matter of choosing concepts in advance and applying them to a text. Instead, it starts with looking at the text in detail and asking the appropriate questions about how it works:

• What is the author’s purpose?
• Do they focus closely on their key claims, or do they discuss various topics?
• What tone do they take—angry or sympathetic? Personal or authoritative? Formal or informal?
• Who seems to be the intended audience? Is this audience likely to be successfully reached and convinced?
• What kinds of evidence are presented?

By asking these questions, you’ll discover the various rhetorical devices the text uses. Don’t feel that you have to cram in every rhetorical term you know—focus on those that are most important to the text.

The following sections show how to write the different parts of a rhetorical analysis.

Like all essays, a rhetorical analysis begins with an introduction . The introduction tells readers what text you’ll be discussing, provides relevant background information, and presents your thesis statement .

Hover over different parts of the example below to see how an introduction works.

Martin Luther King, Jr.’s “I Have a Dream” speech is widely regarded as one of the most important pieces of oratory in American history. Delivered in 1963 to thousands of civil rights activists outside the Lincoln Memorial in Washington, D.C., the speech has come to symbolize the spirit of the civil rights movement and even to function as a major part of the American national myth. This rhetorical analysis argues that King’s assumption of the prophetic voice, amplified by the historic size of his audience, creates a powerful sense of ethos that has retained its inspirational power over the years.

The body of your rhetorical analysis is where you’ll tackle the text directly. It’s often divided into three paragraphs, although it may be more in a longer essay.

Each paragraph should focus on a different element of the text, and they should all contribute to your overall argument for your thesis statement.

Hover over the example to explore how a typical body paragraph is constructed.

King’s speech is infused with prophetic language throughout. Even before the famous “dream” part of the speech, King’s language consistently strikes a prophetic tone. He refers to the Lincoln Memorial as a “hallowed spot” and speaks of rising “from the dark and desolate valley of segregation” to “make justice a reality for all of God’s children.” The assumption of this prophetic voice constitutes the text’s strongest ethical appeal; after linking himself with political figures like Lincoln and the Founding Fathers, King’s ethos adopts a distinctly religious tone, recalling Biblical prophets and preachers of change from across history. This adds significant force to his words; standing before an audience of hundreds of thousands, he states not just what the future should be, but what it will be: “The whirlwinds of revolt will continue to shake the foundations of our nation until the bright day of justice emerges.” This warning is almost apocalyptic in tone, though it concludes with the positive image of the “bright day of justice.” The power of King’s rhetoric thus stems not only from the pathos of his vision of a brighter future, but from the ethos of the prophetic voice he adopts in expressing this vision.

The conclusion of a rhetorical analysis wraps up the essay by restating the main argument and showing how it has been developed by your analysis. It may also try to link the text, and your analysis of it, with broader concerns.

Explore the example below to get a sense of the conclusion.

It is clear from this analysis that the effectiveness of King’s rhetoric stems less from the pathetic appeal of his utopian “dream” than it does from the ethos he carefully constructs to give force to his statements. By framing contemporary upheavals as part of a prophecy whose fulfillment will result in the better future he imagines, King ensures not only the effectiveness of his words in the moment but their continuing resonance today. Even if we have not yet achieved King’s dream, we cannot deny the role his words played in setting us on the path toward it.

The goal of a rhetorical analysis is to explain the effect a piece of writing or oratory has on its audience, how successful it is, and the devices and appeals it uses to achieve its goals.

Unlike a standard argumentative essay , it’s less about taking a position on the arguments presented, and more about exploring how they are constructed.

The term “text” in a rhetorical analysis essay refers to whatever object you’re analyzing. It’s frequently a piece of writing or a speech, but it doesn’t have to be. For example, you could also treat an advertisement or political cartoon as a text.

Logos appeals to the audience’s reason, building up logical arguments . Ethos appeals to the speaker’s status or authority, making the audience more likely to trust them. Pathos appeals to the emotions, trying to make the audience feel angry or sympathetic, for example.

Collectively, these three appeals are sometimes called the rhetorical triangle . They are central to rhetorical analysis , though a piece of rhetoric might not necessarily use all of them.

In rhetorical analysis , a claim is something the author wants the audience to believe. A support is the evidence or appeal they use to convince the reader to believe the claim. A warrant is the (often implicit) assumption that links the support with the claim.

Academic Argument

Rhetorical Strategies: Building Compelling Arguments

Rhetoric pertains to how authors use and manipulate language in order to persuade an audience.

To be rhetorically effective (and thus persuasive), an author must engage the audience in a variety of compelling ways. We can classify these as Logos, Pathos, and Ethos.

Logos: Appeal to Logic

Logic. Reason. Rationality. Logos is brainy and intellectual, cool, calm, collected, objective.

Logically sound writing often includes many examples to support a point – and those examples come from citation of credible data and statistics, reference to sound theories, reference valid research conducted by credible organizations.

Logical appeals rest on rational modes of thinking, such as

• Comparison : you compare one thing (with regard to your topic)  to another, similar thing to help support your claim. It is important that the comparison is fair and valid – the things being compared must share significant traits of similarity.
• Cause/effect thinking : you argue that X has caused Y, or that X is likely to cause Y to help support your claim. Be careful with the latter – it can be difficult to predict that something “will” happen in the future.
• Deductive reasoning : you start with a general claim/example and then use it to justify a in a smaller claim
• Inductive reasoning : you use several specific examples or cases and use them to make a larger generalization
• Exemplification : use of many examples to support a single point

Pathos: Appeal to Emotions

Pathos is deeply human – an author using pathetic appeals wants the audience to feel something: anger or pride or joy or rage or happiness. Pathetic appeals rest on emotion-based modes of communication . To engage the audience on an emotional level, the author may

• add  expressive descriptions of people, places or events that helps the reader to feel or experience those events
• include vivid imagery  of people, places or events that helps the reader to feel like he or she is seeing  those events
• share  personal stories that help the reader feel connected to the person being described
• use vocabulary or sentence structure that revolves around a  particular emotion : sadness, happiness, fear, joy, anger, disgust, horror.
• try to include any information that will evoke an emotional response from the audience . This could involve making the audience feel empathy or disgust for the person/group/event being discussed,  or perhaps connection to or rejection of the person/group/event being discussed.

Pathos-based strategies are any strategies that get the audience to “open up” to the topic or to the author. Emotions can make us vulnerable, and rhetors can use this vulnerability to get the audience on his or her side.

Ethos: Appeal to Values/Trust

Ethical appeals have two facets.

One the one hand, an ethical appeal taps into the  values that the audience holds, for example, patriotism, tradition, justice, equality, dignity for all humankind, self preservation, or other specific social, religious or philosophical values (Christian values, socialism, capitalism, feminism, etc). These values can sometimes feel very close to emotions, but they are felt on a social level rather than only on a personal level. If an author can evoke the values that the audience cares about in his or her argument, then he or she has a chance of persuading that audience because the audience will feel that the author is making an argument that is “right” (in the sense of moral “right”-ness).

This sense of referencing what is “right” in an ethical appeal connects to the   moral character of the speaker/author. The author may draw attention to who he or she is as a way to engage the audience (i.e., “Because I support this – and you all you trust me because we share the same values! – you should, too”). If an author can present his or her moral character, one that the audience trusts because they (author and audience) share values,  then he or she has a chance of persuading that audience. In this sense, the audience will feel that the author is the right person to make this argument and should therefore be believed.

In building ethical appeals, we see authors

• referring either directly or indirectly to the values that matter to the intended audience
• using reasoning or logic that relies on these values
• using language, phrasing, imagery or other writing style common to people who hold those values – tapping into the discourse community of people with those values
• doing anything else that shows the audience that the author understands and shares their values

• When & How to Write a Rhetorical Device

I. What is a Rhetorical Device?

A rhetorical device is any language that helps an author or speaker achieve a particular purpose (usually  persuasion , since rhetoric is typically defined as the art of persuasion). But “rhetorical device” is an extremely broad term, and can include techniques for generating emotion, beauty, and spiritual significance as well as persuasion.

II. Examples of Rhetorical Devices

Hyperbole is a word- or sentence-level rhetorical device in which the author exaggerates a particular point for dramatic effect. For example:

Berlin was flattened during the bombing.

Because the city was not literally left flat, this is an exaggeration, and therefore hyperbole. But it still helps express the author’s main point, which is that the city of Berlin was very severely damaged.

Analogy is an important device in which the explains one thing by comparing it to another. At the sentence level, this might be as simple as saying “my cat’s fur is as white as a cloud .” But analogies can also function at much higher levels, including paragraphs and whole essays . For example, you might argue against war by drawing an extended analogy between the war on terrorism and World War 2. The success of the whole argument would depend entirely on how well you could persuade readers to accept the analogy!

The counterargument is the most important rhetorical device for college-level essays. A counterargument is a response to your own view – for example, if you’re arguing in favor of an idea, the counterargument is one that goes against that idea. In order to make your own argument perspective, you have to acknowledge, analyze, and answer these counterarguments.

III. Types of Rhetorical Devices

Because the term is so broad, there are countless ways to categorize rhetorical devices. For example, we might group them by function: e.g. persuasive devices, aesthetic devices (for creating beauty), or emotional devices. We could also group them according to the types of writing they belong to: e.g. poetry vs. essays.

The clearest way to categorize, though, is probably by scale: that is, what level of the writing does each device affect?

A. Word Level

Before we even get to full sentences, there are many rhetorical devices that operate at the level of individual words or groups of words. For example, the “metonym” is a rhetorical device in which a part stands in for the whole. For example, you might say that a ship is staffed with “twenty hands,” where each hand stands in for a full human being.

B. Sentence Level

Most rhetorical devices operate at the sentence level. They affect the meaning of a sentence, or a chunk of a sentence. For example, parallelism is an important rhetorical device in which different parts of a sentence have the same grammatical structure: “I am disgusted by your methods , but impressed with your results .” Notice how each underlined portion has the same pattern of adjective, preposition, pronoun, and plural noun.

C. Paragraph Level

Paragraph-level rhetorical techniques are especially important in essays, where they help to signal the structure of the argument. One example would be the topic sentence. Topic sentences open the paragraph and introduce its main idea, which is then supported and explained in the body of the paragraph. This is one of the most important techniques for structuring paragraphs effectively.

D. Structural Level

Some rhetorical devices cover the whole structure of a piece of writing. For example, the 5-paragraph essay is a rhetorical device that many people learn in high school for structuring their essays. The five paragraphs involve an introduction, 3 body paragraphs, and a conclusion. This structure is rejected by many college-level writing instructors (and thus may be thought of as a bad rhetorical device), but it’s a rhetorical device nonetheless.

IV. The Importance of Rhetorical Devices

Rhetorical devices are just like artistic techniques – they become popular because they work. For as long as human beings have been using language, we’ve been trying to persuade one another and evoke emotions. Over time, we’ve developed a huge variety of different techniques for achieving these effects, and the sum total of all such techniques is encapsulated in our modern lists of rhetorical techniques. Each rhetorical device has a different purpose, a different history, and a different effect!

V. Examples of Rhetorical Devices in Literature

“If we shadows have offended , think but this and all is mended : that you have but slumbered here while these visions did appear .” (Shakespeare, A Midsummer Night’s Dream )

This famous quote, like many of Shakespeare’s lines, employs rhyme and meter, the two most basic rhetorical devices in verse. Although not all poetry has rhyme or meter, most classical poems do, and these rhetorical devices were probably important in helping poets memorize their works and sing them in front of audiences.

The dialogue form is an important structural device used in philosophy and religious scriptures for thousands of years. By putting different arguments in the mouths of different characters , philosophers can present their readers with a broader range of possible views, thus bringing more nuance into the conversation. This device also allows philosophers to make their own arguments more persuasive by responding to the various counterarguments presented by characters in the dialogue.

VI. Examples of Rhetorical Devices in Popular Culture

(adsbygoogle = window.adsbygoogle || []).push({}); “Ah, yes – Zorro! And where is he now, padre? Your masked friend? He hasn’t shown himself in 20 years!” (Don Rafael, The Mask of Zorro )

A rhetorical question is a question that the audience is not supposed to answer – either because the answer is obvious, or because the speaker is about to answer it for them. It’s one of the most common techniques in oratory (speeches) and essays. In this case, Don Rafael is using a rhetorical question to undermine the crowd’s confidence in Zorro, their legendary defender.

“The microphone explodes, || shattering the mold.” (Rage Against the Machine, Bulls on Parade )

The two vertical lines (||) represent a caesura , or pause. This is a common rhetorical device in poetry, but is also found in music. In the recording of the song, there’s a beat’s pause in between “explodes” and “shattering.”

VII. Related Terms

Rhetoric is the art of persuasion, either through speaking or writing. In ancient Greece, the concept of rhetoric was given huge cultural importance, and philosophers like Aristotle wrote whole books on rhetoric and the techniques of convincing others.

Today, people sometimes view rhetoric in a negative light (as when someone says of a politician’s speech that it was “all rhetoric and no substance”). But this is a shame, since we are very much in need of leaders who have mastered the art of persuasive reasoning and respectful argumentation. Rhetoric has fallen from its former place of honor, and perhaps this explains the lack of productive dialogue in our political arena, driven as it is by sound bites and personal attacks.

Figure of Speech

When a rhetorical device departs from literal truth, this is called a “figure of speech.” The most common figure of speech is a metaphor, in which one thing stands for another (e.g. “he unleashed a hurricane of criticism”). However, many rhetorical devices employ literal truth and therefore should not be thought of as figures of speech.

Sat / act prep online guides and tips, ethos, pathos, logos, kairos: the modes of persuasion and how to use them.

General Education

Ethos, pathos, logos, and kairos all stem from rhetoric—that is, speaking and writing effectively. You might find the concepts in courses on rhetoric, psychology, English, or in just about any other field!

The concepts of ethos, pathos, logos, and kairos are also called the modes of persuasion, ethical strategies, or rhetorical appeals. They have a lot of different applications ranging from everyday interactions with others to big political speeches to effective advertising.

Read on to learn about what the modes of persuasion are, how they’re used, and how to identify them!

What Are the Modes of Persuasion?

As you might have guessed from the sound of the words, ethos, pathos, logos, and kairos go all the way back to ancient Greece. The concepts were introduced in Aristotle’s Rhetoric , a treatise on persuasion that approached rhetoric as an art, in the fourth century BCE.

Rhetoric was primarily concerned with ethos, pathos, and logos, but kairos, or the idea of using your words at the right time, was also an important feature of Aristotle’s teachings.

However, kairos was particularly interesting to the Sophists, a group of intellectuals who made their living teaching a variety of subjects. The Sophists stressed the importance of structuring rhetoric around the ideal time and place.

Together, all four concepts have become the modes of persuasion, though we typically focus on ethos, pathos, and logos.

What Is Ethos?

Though you may not have heard the term before, ‘ethos’ is a common concept. You can think of it as an appeal to authority or character—persuasive techniques using ethos will attempt to persuade you based on the speaker’s social standing or knowledge. The word ethos even comes from the Greek word for character.

An ethos-based argument will include a statement that makes use of the speaker or writer’s position and knowledge. For example, hearing the phrase, “As a doctor, I believe,” before an argument about physical health is more likely to sway you than hearing, “As a second-grade teacher, I believe.”

Likewise, celebrity endorsements can be incredibly effective in persuading people to do things . Many viewers aspire to be like their favorite celebrities, so when they appear in advertisements, they're more likely to buy whatever they're selling to be more like them. The same is true of social media influencers, whose partnerships with brands can have huge financial benefits for marketers .

In addition to authority figures and celebrities, according to Aristotle, we’re more likely to trust people who we perceive as having good sense, good morals, and goodwill —in other words, we trust people who are rational, fair, and kind. You don’t have to be famous to use ethos effectively; you just need whoever you’re persuading to perceive you as rational, moral, and kind.

What Is Pathos?

Pathos, which comes from the Greek word for suffering or experience, is rhetoric that appeals to emotion. The emotion appealed to can be a positive or negative one, but whatever it is, it should make people feel strongly as a means of getting them to agree or disagree.

For example, imagine someone asks you to donate to a cause, such as saving rainforests. If they just ask you to donate, you may or may not want to, depending on your previous views. But if they take the time to tell you a story about how many animals go extinct because of deforestation, or even about how their fundraising efforts have improved conditions in the rainforests, you may be more likely to donate because you’re emotionally involved.

But pathos isn’t just about creating emotion; it can also be about counteracting it. For example, imagine a teacher speaking to a group of angry children. The children are annoyed that they have to do schoolwork when they’d rather be outside. The teacher could admonish them for misbehaving, or, with rhetoric, he could change their minds.

Suppose that, instead of punishing them, the teacher instead tries to inspire calmness in them by putting on some soothing music and speaking in a more hushed voice. He could also try reminding them that if they get to work, the time will pass quicker and they’ll be able to go outside to play.

Aristotle outlines emotional dichotomies in Rhetoric . If an audience is experiencing one emotion and it’s necessary to your argument that they feel another, you can counterbalance the unwanted emotion with the desired one . The dichotomies, expanded upon after Aristotle, are :

• Anger/Calmness
• Friendship/Enmity
• Fear/Confidence
• Shame/Shamelessness
• Kindness/Unkindness
• Pity/Indignation
• Envy/Emulation

Note that these can work in either direction; it’s not just about swaying an audience from a negative emotion to a positive one. 

However, changing an audience's emotion based on false or misleading information is often seen as manipulation rather than persuasion. Getting into the hows and whys requires a dive into the ethics of rhetoric , but suffice to say that when you attempt to deceive an audience, that is manipulation.

If you really want to get an audience fired up about something, you can inspire righteous anger, which may or may not be manipulation. If somebody is offended that you’ve asked them for something, you can try making them feel sorry for you by turning indignation into pity— that’s manipulation.

What Is Logos?

Logos comes from a Greek word of multiple meanings, including “ground,” “speech,” and “reason.” In rhetoric, it specifically refers to having a sense of logic to your persuasion; logos-based rhetoric is founded in logic and reason rather than emotion, authority, or personality.

A logic-based argument appeals to a person’s sense of reason— good logos-based rhetoric will persuade people because the argument is well-reasoned and based in fact. There are two common approaches to logos: deductive and inductive arguments.

Deductive arguments build on statements to reach a conclusion —in effect, the conclusion is reached in reverse. A common method is to propose multiple true statements which are combined to reach a conclusion, such as the classic method of proving that Socrates is mortal.

All men are mortal, and Socrates is a man, therefore Socrates must be mortal.

That’s not really a case that needs to be argued, but we can apply the same framework to other arguments as well. For example, we need energy to live. Food gives the body energy. Therefore, we need food to live.  

All of this is based on things we can prove, and results in a conclusion that is true , not just theorized. Deductive reasoning works on the assumption that A = B, B = C, so therefore A = C. But this also supposes that all the information is true, which is not always the case.

Sometimes the conclusions you reach with deductive reasoning can be valid, as in the reasoning makes sense, but the conclusion may not be necessarily true. If we return to the Socrates argument, we could propose that:

All men eat apples. Socrates is a man. Therefore, Socrates must eat apples.

The problem is that we can’t prove that all men eat apples —some do, some don’t. Some might eat an apple once but never again. But based on our arguments, the conclusion that Socrates must eat apples is valid.

A strong deductive argument for logos-based reasoning will be composed of provable facts that can reach a provable conclusion. However, a valid but not entirely sound argument can also be effective—but be wary of shifting from persuasion to manipulation!

Another approach to logos-based rhetoric is inductive reasoning, which, unlike deductive reasoning, results in a probable argument rather than a definite one. That doesn’t mean that it is less effective—many scientific concepts we accept as truth are inductive theories simply because we cannot travel back in time and prove them— but rather that inductive reasoning is based on eliminating the impossible and ending in an argument that is based in sound logic and fact, but that may not necessarily be provable.

For example, all people with a cough have a cold. Kelly has a cough. Therefore, Kelly likely has a cold.

Our conclusion is likely , but not absolute. It’s possible that Kelly doesn’t have a cold—not because she doesn't have a cough, but because there are other possible causes, such as having allergies or having just breathed in some dust. The conclusion that she has a cold is likely based on data, but not absolute.

Another example would be that Kelly picks her nose. Kelly is a woman, therefore all women must pick their nose.

Inductive reasoning is based on generalizations. The first example, in which Kelly likely has a cold, makes sense because it’s based on something provable—that a sampling of people who have a cough have colds—and followed up with a likely conclusion. In the second example, this is a less sensible conclusion because it’s based on extrapolation from a single reference point.

If we reverse the claim and say that all women pick their noses, and Kelly is a woman, therefore Kelly must pick her nose, that would be more sound logic. Still not necessarily true—not all women pick their noses—but a more sound example of inductive reasoning.

Inductive reasoning can still be incredibly effective in persuasion, provided that your information is well-reasoned. Inductive reasoning creates a hypothesis that can be tested; its conclusion is not necessarily true, but can be examined.

As always, be wary of venturing into manipulation, which is more likely to be based on erroneous or misleading facts.

What Is Kairos?

Kairos is the Greek word for the opportune moment, which is precisely what it means in rhetoric. According to this principle, the time in which an argument is deployed is as important as the argument itself. An argument at the wrong time or to the wrong audience will be wasted; to be effective, you must also consider when you are speaking and to whom.

In effect, kairos means choosing the correct rhetorical device to match the audience and space in which you’re attempting to persuade. If you wanted to persuade people to go vegetarian, the middle of a hot dog-eating contest is probably not the right time. Likewise, you’re probably not going to persuade a room of data-driven scientists of something by appealing to pathos or ethos; logos is probably your best bet.

In essence, kairos asks you to consider the context and atmosphere of the argument you’re making. How can you deploy your argument better considering time and space? Should you wait, or is time of the essence?

As Aristotle famously said, “Anybody can become angry—that is easy, but to be angry with the right person and to the right degree and at the right time and for the right purpose, and in the right way—that is not within everybody's power and is not easy.”

The goal of kairos is to achieve exactly that. Effective use of kairos strengthens your persuasion ability by considering how people are already feeling based on context. How can you influence or counteract that? Or maybe pathos isn’t the right approach—maybe cold hard facts, using logos, is more suited. Kairos works in conjunction with the other modes of persuasion to strengthen your argument, so as you’re putting a persuasive piece together, consider how and when it’ll be deployed!

How to Identify Ethos, Pathos, Logos, and Kairos

Understanding how the modes of persuasion work can make you better at identifying and picking them out. Not only is a better understanding of them useful for composing your own arguments, but it’s also beneficial when seeing other people’s arguments. When you understand how ethos, pathos, logos, and kairos work, you’re less susceptible to them.

Advertising is one of the places we see the modes of persuasion most often. Looking at each of these advertisements, you can see how they use each mode of persuasion to convince audiences to convince an audience of something.

Using celebrities is a classic example of ethos, which uses authority or recognition to convince an audience of something. In this case, celebrities like Michelle Obama, Lin-Manuel Miranda, and Janelle Monáe discuss the importance of voting.

It doesn’t matter that they’re not politicians or political scientists; audiences find them appealing and genuine. When they speak of the importance of voting, audiences listen because they like what these figures have to say . If talented, famous people like this are taking the time to vote, it must be important!

Historians or those well-versed in politics might make different arguments about why audiences should vote, but in this case, the goal is to inspire people. When we see people we admire doing things, we want to do them too; hence the reason that ethos works so well.

ASPCA’s commercials are some of the most infamous examples of pathos in advertising. Sarah McLachlan’s “Angel” plays over footage of abused animals in shelters, encouraging viewers to donate money to support the organization.

It’s not hard to understand why it works; both the song and the imagery are heartbreaking! You can’t help but feel sad when you see it, and that sadness, when followed up by a prompt to donate, encourages you to take immediate action.  And these ads are effective— the campaign raised millions of dollars for ASPCA .

By appealing to our emotions and making us feel sad, this advertisement encourages us to act. That’s a classic use of ethos—it influences our feelings through the one-two punch of sad music and imagery, encouraging us to perform the desired action.

In some cases, emotion and authority aren’t the right tactic. Logos often appears in tech advertisements, such as this one for the iPhone XS and XR.

Notice how the advertisement focuses on product shots and technological terms. Most audiences won’t know what an A12 bionic neural engine is, but it sounds impressive. Likewise, that “12 MPf/1.8 wide-angle lens, with larger, deeper 1.4 micron pixels” is pretty meaningless to most people, but the numbers suggest that this phone is something special because it uses scientific-sounding language.

It doesn’t matter whether audiences really understand what’s being said or not. What matters is that they feel confident that the ad is selling them something they need —in this case, impressive technological specifications that make this phone an improvement over others.

Kairos should ideally factor into all uses of the modes of persuasion, but timeliness can also be a big selling point. In this Christmas-themed M&Ms advertisement, the company uses timely humor to forge a connection between the holidays and M&Ms.

Because these commercials have been running for such a long time, there’s also a nostalgic attachment to them. Just as people look forward to new Budweiser advertisements during the Super Bowl, others look forward to seeing M&Ms or the Coca-Cola polar bear during the holidays.

Though this commercial doesn’t go out of its way to tell you the benefits of M&Ms, it does forge a connection between M&Ms and Christmas, encouraging people to purchase them around the holidays.

Examples of the Modes of Persuasion

Now that you’ve had some exposure to how ethos, pathos, logos, and kairos function and what they can do, you can test your ability to recognize them using the images below!

There are a few things to notice about this image:

• The anonymous figure
• The language
• The use of a statistic

Can you figure out which mode of persuasion this represents?

The fact that the figure is anonymous tells us it’s probably not ethos. While we might be influenced by a person who’s in shape, there’s not really an appeal here based on the person—they’re just an image to support the ad.

“DOMINATE” is a pretty loaded word, suggesting that this may have elements of pathos.

However, take a look at that statistic. Whether it’s true or not, a hard statistic like that suggests that this ad is using logos to appeal to viewers. You can draw out an argument from there—75% of users lose weight within weeks. You’re a user. Therefore, you will likely lose weight within weeks.

What do you notice about this image?

• The way the text frames the woman’s body
• The name of the perfume
• The color choice

What mode of persuasion is this?

Again, we don’t know who the model is, and perfume isn’t going to make us look like her, so we can count ethos out.

The ad seems pretty intent on making us look at certain things—the woman’s lips and chest in particular. What is it trying to make us feel?

“FORBIDDEN FRUIT” has a connotation of sensuality.

Red is a color commonly associated with passion.

When you combine the photo, the framing, the perfume name, and the color, you get a strong sense of sex appeal from the advertisement. This makes it an example of pathos—the ad is trying to make us feel a certain way . If we buy this perfume, maybe we would feel attractive, too.

How about this advertisement?

• A serious-looking photo
• Text promising “no more back pain”
• “Doctor recommended.”

Seeing a doctor might make you tempted to think the answer is logos, but there’s no appeal to logic here.

“No more back pain,” is a nice promise, but there’s no attempt to appeal to emotions, so it can’t be pathos.

What’s important in this image is the combination of the doctor in the image and the line “doctor recommended.” This doctor might not be famous, but he does have authority, making this an example of ethos.

Our confidence in this treatment grows because we trust that a doctor understands how to address back pain.

What mode of persuasion is this?  Think about:

• The framing

She does look fashionable and the ad mentions stylists, so it’s possible that this is ethos.

There are no statistics or arguments being made, so the answer probably isn’t logos.

Pathos is possible, but despite having a heavily made-up model, this ad is far less about sex appeal than the previous one.

But the text mentions a specific holiday—New Year’s—suggesting that this is kairos. Kairos can, and often should, be combined with all the modes of persuasion to be even more effective. In this case, the model’s appearance could suggest either ethos or pathos in addition to kairos. The message here is that you should act now, at the beginning of the year, to take advantage of the deal and to start the year off with a new style, much like the one the model is sporting.

Key Tips for Identifying Ethos, Pathos, Logos, and Kairos

Now that you know the difference between all the modes of persuasion, you’ll have a much easier time identifying them. If you run into trouble, you can always ask questions about what you’re seeing, hearing, or reading to understand what mode of persuasion it’s using.

#1: Is It Related to a Specific Time?

If the argument is based on a specific day or context, such as Valentine’s Day or appealing only to a select group of people, such as people with dogs, it’s more likely to be kairos.

#2: Does It Involve a Celebrity or Authority Figure?

Celebrities are often a dead giveaway that an argument is using ethos. But authority figures, such as doctors, dentists, or politicians, can also be used to appeal to ethos. Even regular, everyday people can work, particularly when combined with pathos, to appeal to you based on a mutual connection you have.

#3: Does It Involve Statistics?

Statistics are a huge clue that an argument is using logos. But logos can also just be a logical argument, such as that if plants need water, and it’s hard to remember to water them, you should buy an automatic plant waterer. It makes perfect sense, making you more likely to buy it, rather than changing your habits to remember to water your plants more frequently.

#4: Does It Influence Your Emotions?

If an argument tries to change your emotions, whether by making you sad, happy, angry, or something else entirely, it’s a good indicator that it’s using pathos. Sex appeal is one of the biggest examples of pathos in advertising, appearing everywhere from makeup ads to car commercials to hamburger advertisements.

9.5 Writing Process: Thinking Critically about Rhetoric

Learning outcomes.

By the end of this section, you will be able to:

• Develop a rhetorical analysis through multiple drafts.
• Identify and analyze rhetorical strategies in a rhetorical analysis.
• Demonstrate flexible strategies for generating ideas, drafting, reviewing, collaborating, revising, rewriting, and editing.
• Give and act on productive feedback for works in progress.

The ability to think critically about rhetoric is a skill you will use in many of your classes, in your work, and in your life to gain insight from the way a text is written and organized. You will often be asked to explain or to express an opinion about what someone else has communicated and how that person has done so, especially if you take an active interest in politics and government. Like Eliana Evans in the previous section, you will develop similar analyses of written works to help others understand how a writer or speaker may be trying to reach them.

Summary of Assignment: Rhetorical Analysis

The assignment is to write a rhetorical analysis of a piece of persuasive writing. It can be an editorial, a movie or book review, an essay, a chapter in a book, or a letter to the editor. For your rhetorical analysis, you will need to consider the rhetorical situation—subject, author, purpose, context, audience, and culture—and the strategies the author uses in creating the argument. Back up all your claims with evidence from the text. In preparing your analysis, consider these questions:

• What is the subject? Be sure to distinguish what the piece is about.
• Who is the writer, and what do you know about them? Be sure you know whether the writer is considered objective or has a particular agenda.
• Who are the readers? What do you know or what can you find out about them as the particular audience to be addressed at this moment?
• What is the purpose or aim of this work? What does the author hope to achieve?
• What are the time/space/place considerations and influences of the writer? What can you know about the writer and the full context in which they are writing?
• What specific techniques has the writer used to make their points? Are these techniques successful, unsuccessful, or questionable?

For this assignment, read the following opinion piece by Octavio Peterson, printed in his local newspaper. You may choose it as the text you will analyze, continuing the analysis on your own, or you may refer to it as a sample as you work on another text of your choosing. Your instructor may suggest presidential or other political speeches, which make good subjects for rhetorical analysis.

When you have read the piece by Peterson advocating for the need to continue teaching foreign languages in schools, reflect carefully on the impact the letter has had on you. You are not expected to agree or disagree with it. Instead, focus on the rhetoric—the way Peterson uses language to make his point and convince you of the validity of his argument.

Another Lens. Consider presenting your rhetorical analysis in a multimodal format. Use a blogging site or platform such as WordPress or Tumblr to explore the blogging genre, which includes video clips, images, hyperlinks, and other media to further your discussion. Because this genre is less formal than written text, your tone can be conversational. However, you still will be required to provide the same kind of analysis that you would in a traditional essay. The same materials will be at your disposal for making appeals to persuade your readers. Rhetorical analysis in a blog may be a new forum for the exchange of ideas that retains the basics of more formal communication. When you have completed your work, share it with a small group or the rest of the class. See Multimodal and Online Writing: Creative Interaction between Text and Image for more about creating a multimodal composition.

Quick Launch: Start with a Thesis Statement

After you have read this opinion piece, or another of your choice, several times and have a clear understanding of it as a piece of rhetoric, consider whether the writer has succeeded in being persuasive. You might find that in some ways they have and in others they have not. Then, with a clear understanding of your purpose—to analyze how the writer seeks to persuade—you can start framing a thesis statement : a declarative sentence that states the topic, the angle you are taking, and the aspects of the topic the rest of the paper will support.

Complete the following sentence frames as you prepare to start:

• The subject of my rhetorical analysis is ________.
• My goal is to ________, not necessarily to ________.
• The writer’s main point is ________.
• I believe the writer has succeeded (or not) because ________.
• I believe the writer has succeeded in ________ (name the part or parts) but not in ________ (name the part or parts).
• The writer’s strongest (or weakest) point is ________, which they present by ________.

Drafting: Text Evidence and Analysis of Effect

As you begin to draft your rhetorical analysis, remember that you are giving your opinion on the author’s use of language. For example, Peterson has made a decision about the teaching of foreign languages, something readers of the newspaper might have different views on. In other words, there is room for debate and persuasion.

The context of the situation in which Peterson finds himself may well be more complex than he discusses. In the same way, the context of the piece you choose to analyze may also be more complex. For example, perhaps Greendale is facing an economic crisis and must pare its budget for educational spending and public works. It’s also possible that elected officials have made budget cuts for education a part of their platform or that school buildings have been found obsolete for safety measures. On the other hand, maybe a foreign company will come to town only if more Spanish speakers can be found locally. These factors would play a part in a real situation, and rhetoric would reflect that. If applicable, consider such possibilities regarding the subject of your analysis. Here, however, these factors are unknown and thus do not enter into the analysis.

Introduction

One effective way to begin a rhetorical analysis is by using an anecdote, as Eliana Evans has done. For a rhetorical analysis of the opinion piece, a writer might consider an anecdote about a person who was in a situation in which knowing another language was important or not important. If they begin with an anecdote, the next part of the introduction should contain the following information:

• Author’s name and position, or other qualification to establish ethos
• Title of work and genre
• Author’s thesis statement or stance taken (“Peterson argues that . . .”)
• Brief introductory explanation of how the author develops and supports the thesis or stance
• If relevant, a brief summary of context and culture

Once the context and situation for the analysis are clear, move directly to your thesis statement. In this case, your thesis statement will be your opinion of how successful the author has been in achieving the established goal through the use of rhetorical strategies. Read the sentences in Table 9.1 , and decide which would make the best thesis statement. Explain your reasoning in the right-hand column of this or a similar chart.

The introductory paragraph or paragraphs should serve to move the reader into the body of the analysis and signal what will follow.

Your next step is to start supporting your thesis statement—that is, how Octavio Peterson, or the writer of your choice, does or does not succeed in persuading readers. To accomplish this purpose, you need to look closely at the rhetorical strategies the writer uses.

First, list the rhetorical strategies you notice while reading the text, and note where they appear. Keep in mind that you do not need to include every strategy the text contains, only those essential ones that emphasize or support the central argument and those that may seem fallacious. You may add other strategies as well. The first example in Table 9.2 has been filled in.

When you have completed your list, consider how to structure your analysis. You will have to decide which of the writer’s statements are most effective. The strongest point would be a good place to begin; conversely, you could begin with the writer’s weakest point if that suits your purposes better. The most obvious organizational structure is one of the following:

• Go through the composition paragraph by paragraph and analyze its rhetorical content, focusing on the strategies that support the writer’s thesis statement.
• Address key rhetorical strategies individually, and show how the author has used them.

As you read the next few paragraphs, consult Table 9.3 for a visual plan of your rhetorical analysis. Your first body paragraph is the first of the analytical paragraphs. Here, too, you have options for organizing. You might begin by stating the writer’s strongest point. For example, you could emphasize that Peterson appeals to ethos by speaking personally to readers as fellow citizens and providing his credentials to establish credibility as someone trustworthy with their interests at heart.

Following this point, your next one can focus, for instance, on Peterson’s view that cutting foreign language instruction is a danger to the education of Greendale’s children. The points that follow support this argument, and you can track his rhetoric as he does so.

You may then use the second or third body paragraph, connected by a transition, to discuss Peterson’s appeal to logos. One possible transition might read, “To back up his assertion that omitting foreign languages is detrimental to education, Peterson provides examples and statistics.” Locate examples and quotes from the text as needed. You can discuss how, in citing these statistics, Peterson uses logos as a key rhetorical strategy.

In another paragraph, focus on other rhetorical elements, such as parallelism, repetition, and rhetorical questions. Moreover, be sure to indicate whether the writer acknowledges counterclaims and whether they are accepted or ultimately rejected.

The question of other factors at work in Greendale regarding finances, or similar factors in another setting, may be useful to mention here if they exist. As you continue, however, keep returning to your list of rhetorical strategies and explaining them. Even if some appear less important, they should be noted to show that you recognize how the writer is using language. You will likely have a minimum of four body paragraphs, but you may well have six or seven or even more, depending on the work you are analyzing.

In your final body paragraph, you might discuss the argument that Peterson, for example, has made by appealing to readers’ emotions. His calls for solidarity at the end of the letter provide a possible solution to his concern that the foreign language curriculum “might vanish like a puff of smoke.”

Use Table 9.3 to organize your rhetorical analysis. Be sure that each paragraph has a topic sentence and that you use transitions to flow smoothly from one idea to the next.

As you conclude your essay, your own logic in discussing the writer’s argument will make it clear whether you have found their claims convincing. Your opinion, as framed in your conclusion, may restate your thesis statement in different words, or you may choose to reveal your thesis at this point. The real function of the conclusion is to confirm your evaluation and show that you understand the use of the language and the effectiveness of the argument.

In your analysis, note that objections could be raised because Peterson, for example, speaks only for himself. You may speculate about whether the next edition of the newspaper will feature an opposing opinion piece from someone who disagrees. However, it is not necessary to provide answers to questions you raise here. Your conclusion should summarize briefly how the writer has made, or failed to make, a forceful argument that may require further debate.

Peer Review: Guidelines toward Revision and the “Golden Rule”

Now that you have a working draft, your next step is to engage in peer review, an important part of the writing process. Often, others can identify things you have missed or can ask you to clarify statements that may be clear to you but not to others. For your peer review, follow these steps and make use of Table 9.4 .

• Quickly skim through your peer’s rhetorical analysis draft once, and then ask yourself, What is the main point or argument of my peer’s work?
• Highlight, underline, or otherwise make note of statements or instances in the paper where you think your peer has made their main point.
• Look at the draft again, this time reading it closely.
• Ask yourself the following questions, and comment on the peer review sheet as shown.

The Golden Rule

An important part of the peer review process is to keep in mind the familiar wisdom of the “Golden Rule”: treat others as you would have them treat you. This foundational approach to human relations extends to commenting on others’ work. Like your peers, you are in the same situation of needing opinion and guidance. Whatever you have written will seem satisfactory or better to you because you have written it and know what you mean to say.

However, your peers have the advantage of distance from the work you have written and can see it through their own eyes. Likewise, if you approach your peer’s work fairly and free of personal bias, you’re likely to be more constructive in finding parts of their writing that need revision. Most important, though, is to make suggestions tactfully and considerately, in the spirit of helping, not degrading someone’s work. You and your peers may be reluctant to share your work, but if everyone approaches the review process with these ideas in mind, everyone will benefit from the opportunity to provide and act on sincerely offered suggestions.

Revising: Staying Open to Feedback and Working with It

Once the peer review process is complete, your next step is to revise the first draft by incorporating suggestions and making changes on your own. Consider some of these potential issues when incorporating peers’ revisions and rethinking your own work.

• Too much summarizing rather than analyzing
• Too much informal language or an unintentional mix of casual and formal language
• Too few, too many, or inappropriate transitions
• Illogical or unclear sequence of information
• Insufficient evidence to support main ideas effectively
• Too many generalities rather than specific facts, maybe from trying to do too much in too little time

In any case, revising a draft is a necessary step to produce a final work. Rarely will even a professional writer arrive at the best point in a single draft. In other words, it’s seldom a problem if your first draft needs refocusing. However, it may become a problem if you don’t address it. The best way to shape a wandering piece of writing is to return to it, reread it, slow it down, take it apart, and build it back up again. Approach first-draft writing for what it is: a warm-up or rehearsal for a final performance.

Suggestions for Revising

When revising, be sure your thesis statement is clear and fulfills your purpose. Verify that you have abundant supporting evidence and that details are consistently on topic and relevant to your position. Just before arriving at the conclusion, be sure you have prepared a logical ending. The concluding statement should be strong and should not present any new points. Rather, it should grow out of what has already been said and return, in some degree, to the thesis statement. In the example of Octavio Peterson, his purpose was to persuade readers that teaching foreign languages in schools in Greendale should continue; therefore, the conclusion can confirm that Peterson achieved, did not achieve, or partially achieved his aim.

When revising, make sure the larger elements of the piece are as you want them to be before you revise individual sentences and make smaller changes. If you make small changes first, they might not fit well with the big picture later on.

One approach to big-picture revising is to check the organization as you move from paragraph to paragraph. You can list each paragraph and check that its content relates to the purpose and thesis statement. Each paragraph should have one main point and be self-contained in showing how the rhetorical devices used in the text strengthen (or fail to strengthen) the argument and the writer’s ability to persuade. Be sure your paragraphs flow logically from one to the other without distracting gaps or inconsistencies.

17 Rhetorical Modes for Paragraphs & Essays

Questions to Ponder

Before you read this chapter, discuss with partners:

• What are rhetorical modes (also called “patterns of organization” and “methods of development”)? Can you list some examples?
• Why are rhetorical modes important in writing? Jot down your ideas.

Now read the graphic below. Can you add to the list of rhetorical modes that you created with your partners?

Rhetorical Modes

Rhetorical modes are also called patterns of organization or methods of development ; they are the ways that authors and speakers organize their ideas to communicate effectively. The rhetorical modes that are covered here are best used as ways to look at what’s already happening in your draft and to consider how you might emphasize or expand on any existing patterns. You might already be familiar with some of these patterns because instructors will sometimes assign them as the purpose for writing an essay. For example, you might have been asked to write a cause and effect essay or a comparison and contrast essay.

Patterns of organization or methods of developing content usually happen naturally as a consequence of the way the writer engages with and organizes information while writing. That is to say, most writers don’t sit down and say, “I think I’ll write a cause and effect essay today.”  Instead, a writer might be more likely to be interested in a topic, say, the state of drinking water in the local community, and as the writer begins to explore the topic, certain cause and effect relationships between environmental pollutants and the community water supply may begin to emerge . And in fact, many times, one essay may incorporate two or more rhetorical modes, as the author makes an argument for their point of view.

Activity A ~ Brainstorming Rhetorical Modes

Pause here to brainstorm ideas with your partner. Using the chart above (“ Choosing Paragraph Patterns “), discuss some of the topics below. Which mode(s) might you use in an essay about these topics? Would you need to explore more than one rhetorical mode for each topic?

• Gender roles
• Race in America
• The value of art in society
• Travel as part of a well-rounded education
• Drugs and alcohol
• Advice to new parents
• Advice to teachers
• The value of making mistakes
• How you’d spend a million dollars
• What a tough day at work taught you about yourself or others
• My family history
• Your idea: ___________

Keep reading to consider some of the ways that these strategies can help you as you revise a draft.

Cause/Effect

Do you see a potential cause-and-effect relationship developing in your draft?  The cause/effect pattern may be used to identify one or more causes followed by one or more effects or results. Or you may reverse this sequence and describe effects first and then the cause or causes. For example, the causes of water pollution might be followed by its effects on both humans and animals. Use the signal words cause ,  effect , and  result , to cue the reader about your about the relationships that you’re establishing.

Here’s an example article from T he New York Times , “ Rough Times Take Bloom Off a New Year’s Rite, the Rose Parade ,” that explores the cause and effect relationship (from 2011) between Pasadena’s budgetary challenges and the ability of their Rose Parade floats to deck themselves out in full bloom.

Problem/Solution

At some point does your essay explore a problem or suggest a solution? The problem/solution pattern is commonly used in identifying something that’s wrong and in contemplating what might be done to remedy the situation. For example, the problem of water pollution could be described, followed by ideas of new ways to solve the problem. There are probably more ways to organize a problem/solution approach, but here are three possibilities:

• Describe the problem, followed by the solution
• Propose the solution first and then describe the problems that motivated it
• Explain a problem, followed by several solutions, and select one solution as the best

Emphasize the words problem  and  solution  to signal these sections of your paper for your reader.

Here’s an example article from T he New York Times , “ Monks Embrace Web to Reach Recruits ,” that highlights an unexpected approach by a group of Benedictine monks in Rhode Island; they’ve turned to social media to grow their dwindling membership.

Compare/Contrast

Are you trying to define something? Do you need your readers to understand what something is and what it is not? The compare-and-contrast method of development is particularly useful in extending a definition, or anywhere you need to show how a subject is like or unlike another subject. For example, the statement is often made that drug abuse is a medical problem instead of a criminal justice issue. An author might attempt to prove this point by comparing drug addiction to AIDS, cancer, or heart disease to redefine the term “addiction” as a medical problem. A statement in opposition to this idea could just as easily establish contrast by explaining all the ways that addiction is different from what we traditionally understand as an illness. In seeking to establish comparison or contrast in your writing, some words or terms that might be useful are by contrast ,  in comparison ,  while ,  some , and  others .

Here’s an example article from T he New York Times “ Who Wants to Shop in a Big Box Store, Anyway? ” The author explores some interesting differences between the average American and average Indian consumer to contemplate the potential success of big box stores in India and also to contemplate why these giant big box corporations, like Walmart or Target, might have to rethink their business model.

These three methods of development—cause/effect, problem/solution, and compare/contrast—are just a few ways to organize and develop ideas and content in your essays. It’s important to note that they should not be a starting point for writers who want to write something authentic, to discuss something that they care deeply about. Instead, they can be a great way to help you look for what’s already happening with your topic or in a draft, to help you to write more, or to help you reorganize some parts of an essay that seem to lack connection or feel disjointed.

Sometimes writers incorporate a variety of modes in any one essay. For example, under the umbrella of an argument essay, and author might choose to write paragraphs showing cause and effect, description, and narrative. The rhetorical mode writers choose depends on the purpose for writing. Rhetorical modes are a set of tools that will give you greater flexibility and effectiveness in communicating with your audience and expressing ideas.

In addition to cause/effect , problem/solution , and compare/contrast , there are many other types of rhetorical modes:

• Classification and division , often used in science, takes large ideas and divides them into manageable chunks of information, classifying and organizing them into types and parts.
• Definition  clarifies the meaning of terms and concepts, providing context and description for deeper understanding of those ideas.
• Description  provides detailed information using adjectives that appeal to the five senses (what people see, hear, smell, taste, and touch) as well as other vivid details that help readers visualize or understand an item or concept.
• Evaluation  analyzes and judges the value and merit of an essay, a concept, or topic.
• Illustration  provides examples and evidence in detail to support, explain, and analyze a main point or idea.
• Narrative  uses fictional or nonfictional stories in a chronological sequence of events, often including detailed descriptions and appeals to the senses and emotions of readers while storytelling to reveal a theme or moment.
• Persuasion  (i.e., argumentation) logically attempts to convince readers to agree with an opinion or take an action; the argument also acknowledges opposing viewpoints and accommodates and/or refutes them with diplomatic and respectful language, as well as provides precise and accurate evidence and other expert supporting details.
• Process analysis  describes and explains, step by step, chronologically, in detail, and with precision and accuracy, how to do something or how something works.

Assignment prompts for college essays may require a specific rhetorical mode, or you may be able to choose the best mode(s) to express your ideas clearly. Either way, be sure to ask your instructor if you are not sure which rhetorical mode(s) to use.

Key Takeaways

Why are rhetorical modes important?

• As readers, understanding an author’s rhetorical mode helps us to understand the text, and to read and think critically.
• Knowing the rhetorical mode helps us to identify the author’s main ideas, which helps us to summarize the author’s work.
• As writers, we use rhetorical modes to make our writing clearer; they help us signal our topic and direction to our readers.
• Rhetorical modes also help us to develop support and keep our readers interested.

Activity B ~ Identifying Rhetorical Modes

• Read a printed or online essay or article. A letter to the editor or an editorial from a newspaper would be perfect. Then, with a partner, identify the modes of writing found in the article. (Use the lists above to help.) Analyze the different choices the writer has made about language and organization to express a point of view. Notice how the author may combine rhetorical modes (for example, a problem-solution article that uses cause-and-effect organization in some paragraphs, or a definition pattern that uses narrative or compare and contrast paragraphs to develop similarities or differences).
• Select, read, and annotate a sample student essay in a specific style as provided in “ Readings: Examples of Essays ” from Saylor Academy . Note in the margins or on another sheet of paper what rhetorical mode each paragraph uses, how those modes and paragraphs support the overall rhetorical mode of the essay, and whether each paragraph does so successfully or not. Discuss in small groups and summarize your findings to report to the rest of the class.

If you want to learn more about three common rhetorical modes, read what the New York Times  has to say in their learning blog article, “ Compare-Contrast, Cause-Effect, Problem Solution: Common ‘Text Types’ in The Times .”

8 Rhetorical Strategies to Persuade Your Audience

If you’ve ever had a conversation with someone who thinks the opposite of you, then you know how challenging it is to persuade them. Even when addressing a receptive audience, having people join your side takes skill and precision. Persuasion is far from an exact science, but influential leaders know how to weave different rhetorical strategies together to create a compelling argument. Their rhetorical choices form the backbone of their persuasion technique, which you can emulate to perfect your own skills. Whether preparing a new speech or writing an article, you can use these strategies to move people closer to your point of view.

What Are Rhetorical Strategies?

Common rhetorical choices, 1. similes and metaphors, examples of similes, examples of metaphors, 2. euphemisms, examples of euphemisms, 3. chiasmus, examples of chiasmus, 4. cause and effect.

You can also use ethos to convince people of your opinion. This rhetorical device involves appealing to others’ sense of  ethical values  by showing your credibility, reliability, and good character. This isn’t always a simple feat to pull off, especially when people have little familiarity with you. However, establishing that you’re trustworthy helps sway people to your side.

How to gain the audience’s trust:

8. narration.

Narration, which is essentially storytelling, is another strategy you can use to connect with your audience. People identify with stories more than they do statistics, even in academic writing. The best storytellers seamlessly incorporate their evidence and arguments into the stories they share. That doesn’t mean an entire speech or article should consist of one or multiple stories, but they can back up the central point of your argument. The right story at the right time can serve as the exclamation point of your persuasive piece, whether it’s real or a rhetorical situation. It’s a powerful strategy that helpfully places issues in perspective.

Avoid Logical Fallacies

The power of persuasion is yours.

The above rhetorical strategies can help you start writing or practicing a verbal argument that persuades people to come to your side of the fence. In business, the power to influence others through  assertive communication  is essential once you know what course you want to take. No matter the debate, also show respect and courtesy and don’t let arguments become personal. For example, you might want to ask the other person genuine questions about their position. Through a healthy and polite discourse, you’ll eventually reach an agreement that both sides can appreciate.

Printing a New Age of Design: A Rhetorical Analysis of Neri Oxman’s TED Talk: “Design at the Intersection of Technology and Biology”

By Jason Piechota

Published: June 06, 2024

Could scientists 3D print a human? What about a finger? As the ability to additively manufacture and 3D print components became easier and cheaper with the 2000s, designers looked to additive manufacturing as a potential way to approach new design problems. One designer, Neri Oxaman, details her work with additive manufacturing within a biological framework in her 2015 TED Talk, “Design at the Intersection of Technology and Biology.” In the talk, Neri Oxman’s use of comparison between current design and her work establishes a base for her argument that her technology is more sustainable than current design. Oxman then utilizes different rhetorical devices to create a presentation that focuses on appeals to the audience’s values and involvement in design, which aid in creating a persuasive argument for the implementation of her technology.

Neri Oxman employs a harsh juxtaposition between manmade and natural language to appeal to the world’s rising belief that design should shift to more sustainable, environmentally friendly methods. In 2015, the same year as the TED Talk, the United Nations launched their sustainable development agenda to address the growing movement towards creating a more sustainable future. Part of the plan of action is the 2030 Agenda, which calls for creating “sustainable cities and communities” alongside “responsible production and consumption” (“Support Sustainable Development”). In the linguistic mode of the talk, Oxman “focuses on [her] language use and specific word choice” to appeal to the growing call for sustainable design (Carroll 55). Oxman highlights the difference between parts and continuous material, noting that a steel dome is “made of thousands of steel parts,” while the silk dome is made “of a single silk thread” (Oxman 00:01-00:26). The comparison between “thousands” and “single” emphasizes the difference in the large quantities of the world’s common assemblies to her new work. “Steel parts” and “silk thread” also illuminates that while her technology is still developed by man, it is entirely made of a component that has already existed in nature and was not manufactured by man. The manufacturing of “thousands” of man made steel parts can create environmentally harmful byproducts when being produced, while the cultivating the “silk thread” from a caterpillar creates no negative effect. Oxman continues that the steel dome is “synthetic,” and “the other [dome] organic” (Oxman 00:01-00:26). Directly pitting “synthetic” with “organic” suggests that Oxman’s work is produced in a more sustainable method than current design. “Organic” gives the impression that Oxman’s design can be decomposed in a safe manner, while “synthetic” brings connotations of materials that will either fail to decay, or will harm the environment. Through her careful language choice, Oxman creates an image of her work that emphasizes a new sustainable way of design in order to produce materials that do not generate negative environmental effects through their production or decomposition.

Oxman builds off of the juxtaposition to illuminate the similarities in overall function between her work and current design through the use of visual aids. The start of Oxman’s presentation immediately shows two different domes, side by side (See fig. 1), as she uses the visual aids to “position the spectator as an active participant in the making of meaning” (Benson 197). She places a manufactured dome on the left side of the visual, and her silk designed dome on the right side. As the viewer progresses from the left to right, they are invited to interpret the connection between the two domes. Oxman’s visual of her designed dome having a similar shape, structure, and background lighting pushes the audience to “make meaning” of the direct comparison between the two domes. The similarities in the visuals allows the audience to imply that the new design has an analogous function to the one of the currently accepted dome. Oxman continues by using a technique of reframing the photographs in order to “provide close-ups of [things] barely noticeable in the original photograph, thus inviting viewers to question why this is so” (Lancioni 398). She drastically zooms in on the two domes to show their structures (See fig. 2). The clear similarity in color and web-like appearance pushes the audience to draw the conclusion that the function and structure of the newly designed dome follows the current approach, but takes a new approach. Oxman then looks to influence the connotation the audience has with her new design by placing visuals of models wearing her work on modeling runways (See fig. 3). The visual of the technology in a modeling show encourages the audience to associate runway fashion qualities of luxury, high quality, and innovation with Oxman’s work. Oxman’s use of visual aids helps her subtly promote the message that her new technology has a proven function and is a higher quality product in comparison to current design.

After using visual aids to cement the logistical appeal of her design, Oxman seeks to appeal to the emotional response of the audience through the use of religious values within a biblical allusion. According to a Pew Research Center demographic analysis in 2015, Christians made up about 31% of the world’s population, the largest religious group in the world (Hackett and McClendon). Knowing that her talk will reach a large global audience due to TED’s prominence, Oxman “tailor[s] it to a particular audience” through the use of a biblical story (Herrick 19). Oxman recalls a biblical story where there was a fruit tree, but “there was to be no differentiation between trunk, branches, leaves and fruit. The whole tree was a fruit” (Oxman 5:40-6:42). She uses the story to emphasize that the tree is made of a single part, similar to the production of her own work. Immediately after introducing the story, Oxman claims that her team “looked for that biblical material,” and “found it” (Oxman 6:42-7:15). The description of finding biblical material creates an implicit comment on the material of Oxman’s design. Oxman attempts to “alter the symbolic framework [her audience employs] to organize their thinking” so that a religious audience immediately associates their predisposed, positive, biblical qualities with her work (Herrick 19). Oxman’s awareness of the audience and her talk’s outreach allows her to effectively persuade a portion of the audience by connecting her work to their deeper, unwavering personal values.

Oxman expands on her emotional appeal by establishing a personal bond between the audience and her work. She utilizes displaying human emotion and using collective pronouns in order to construct a personal bias for the audience’s view of her technology. Oxman introduces her team with a photo board of their headshots, and a picture of their hands next to them. Suddenly, the students begin to laugh and smile, while their hands begin working on different tasks next to each other (Oxman 2:29-3:27). The emotion that is displayed in the video allows Oxman to effectively “persuade through the character” of her team by showing the audience that they are not a distant group of scientists, but resemble the people sitting besides them (Selzer 287). The audience having a more grounded connection to the team enables Oxman to directly include the audience in her work, telling them that “[w]e live in a very special time in history, a rare time” (Oxman 2:29-3:27). The use of the collective “we” immediately places the audience within a context of Oxman’s work. They are not just observers of a creation, they are active participants in the change her work is bringing. Oxman also focuses on describing the time period as “special” and “rare” to give the audience a unique sense of relation to the project; they are the first ones throughout their genealogy who can experience Oxman’s work. Oxman’s ability to give the audience an interpersonal relation to her work puts them at a disposition to be more accepting of new views and potentially have a subtle bias towards the work they are connected to. Oxman’s progression from a logical comparison of her work and current design to an emotional appeal towards her audience’s values signals a focus on the connection between her technology and the audience.

A critical analysis of Oxman’s talk suggests that she uses a deliberative styled approach in her claims in order to achieve a single goal of having her work adopted by society. Selzer characterizes deliberative rhetoric as being “organized around the kinds of decisions a civic or social organization must make (about a future course of action)” (Selzer 284). Oxman describes her collection of wearable technology as “the future of our race on our planet and beyond,” which will help society “move away from the age of the machine” (Oxman 11:39-12:37). Oxman gives the audience a blueprint for the future of technology with her work, and proposes that the audience must choose to adopt the new technology over the current systems in place. The use of deliberative rhetoric establishes a forceful tone, suggesting that Oxman’s main goal is to push her technology for its own success.

While Oxman’s use of deliberative rhetoric may underline an ultimate goal to have her work adopted by the current world, her focus on incorporating epideictic rhetoric creates a more persuasive argument for adopting her work. By focusing on the community the audience is a part of, Oxman articulates an overall goal of improving society through reevaluating design beliefs, something that is more inclusive of the audience’s interests. Selzer claims that “in epideictic discourse, the audience is asked to reconsider beliefs and values” (Selzer 284). Oxman challenges the audience’s views on design by asking multiple questions, such as “[w]hat would design be like if objects were made of a single part?” (Oxman 5:40-6:42). Oxman specifically questions the current assemblies that are made up of thousands of parts, and are integrated into daily life. While her technology fits the criteria of being a single part, Oxman aims to question how the current world could view design in new lenses in order to improve. After asking the audience to reconsider the current state, she then asks, “[w]ould we return to a better state of creation?” (Oxman 5:40-6:42). Oxman asking if adopting new beliefs would not only change the current system of design, but “return” to a “better state” suggests that the present design process is flawed, but she does not immediately follow that her work is the solution. Oxman’s deliberative rhetoric tells the audience that they must accept her work, but the epideictic rhetoric gives the audience agency. The audience feels as though they are tasked in assessing how their community adopts design standards because Oxman makes them feel as though they have a choice in what the standards are. Owing to Oxman's strategic framing of her argument, the audience has the agency in deciding to adopt Oxman’s design and is able to enthusiastically drive the direction of the future.

Neri Oxman’s use of rhetorical strategies helps her create a persuasive argument for the audience to reconsider the design values that are currently being deployed. Oxman pushes her own technology, but also raises the question of how the world can adapt to more sustainable design through additive manufacturing. Can whole buildings be 3D printed with organic materials? Can a building be composed of a single component? By reconsidering how to design, the world can investigate new sustainable approaches to old and arising problems alike. With additive manufacturing, the future of human design may lead not only to new technological breakthroughs, but also a more symbiotic relationship between the Earth and its inhabitants.

Jason Piechota

Jason Piechota is a sophomore at the University of Notre Dame studying Mechanical Engineering. Interested in design, Jason analyzed Neri Oxman’s TED Talk, “Design at the Intersection of Technology and Biology,” where Oxman outlines a new approach to design. His essay investigates the different rhetorical techniques employed by Oxman in order to promote biological additive manufacturing, which may prove to be a viable solution to many design problems. In the future, Jason hopes to find a job within the automotive industry, specifically focusing on design. He would like to thank his family and friends for their support, and Dr. McLaughlin for her help in forming his analysis.
