Understand The Difference Between Ethos, Pathos, And Logos To Make Your Point

During an argument, people will often say whatever is necessary to win. If that is the case, they would certainly need to understand the three modes of persuasion, also commonly known as the three rhetorical appeals: ethos , pathos , and logos . In short, these three words refer to three main methods that a person can use to speak or write persuasively. As you’re about to find out, the modes of persuasion are important because a speaker who knows how to effectively use them will have a significant advantage over someone who doesn’t.

The terms ethos , pathos , and logos and the theory of their use can be traced back to ancient Greece to the philosophy of Aristotle . Aristotle used these three concepts in his explanations of rhetoric , or the art of influencing the thought and conduct of an audience. For Aristotle, the three modes of persuasion specifically referred to the three major parts of an argument: the speaker ( ethos ), the argument itself ( logos ), and the audience ( pathos ). In particular, Aristotle focused on the speaker’s character, the logic and reason presented by an argument, and the emotional impact the argument had on an audience.

While they have ancient roots, these modes of persuasion are alive and well today. Put simply, ethos refers to persuasion based on the credibility or authority of the speaker, pathos refers to persuasion based on emotion, and logos refers to persuasion based on logic or reason.

By effectively using the three modes of persuasion with a large supply of rhetorical devices, a speaker or writer can become a master of rhetoric and win nearly any argument or win over any audience. Before they can do that, though, they must know exactly what ethos , pathos , and logos mean. Fortunately, we are going to look closely at each of these three ideas and see if they are really as effective as they are said to be.

⚡️ Quick summary

Ethos , pathos , and logos are the three classical modes of persuasion that a person can use to speak or write persuasively. Specifically:

• ethos (character): known as “the appeal to authority” or “the appeal to credibility.” This is the method in which a person relies on their credibility or character when making an appeal or an argument.
• pathos (emotions): known as “the appeal to emotion.” Pathos refers to the method of trying to persuade an audience by eliciting some kind of emotional reaction.
• logos (logic): known as “the appeal to reason.” This method involves using facts and logical reasoning to support an argument and persuade an audience.

What is ethos ?

The word ethos comes straight from Greek. In Greek, ethos literally translates to “habit,” “custom,” or “character.” Ethos is related to the words ethic and ethical , which are typically used to refer to behavior that is or isn’t acceptable for a particular person.

In rhetoric, the word ethos is used to refer to the character or reputation of the speaker. As a rhetorical appeal, ethos is known as “the appeal to authority” or “the appeal to credibility.” When it comes to ethos , one important consideration is how the speaker carries themself and how they present themselves to the audience: Does it seem like they know what they are talking about? Do they even believe the words they are saying? Are they an expert? Do they have some experience or skills that tell us we should listen to them?

Ethos is important in rhetoric because it often influences the opinion or mood of the audience. If a speaker seems unenthusiastic, unprepared, or inexperienced, the audience is more likely to discount the speaker’s argument regardless of what it even is. On the other hand, a knowledgeable, authoritative, confident speaker is much more likely to win an audience over.

Ethos often depends on more than just the argument itself. For example, a speaker’s word choice, grammar, and diction also contribute to ethos ; an audience may react more favorably toward a professional speaker who has a good grasp of industry jargon and enunciates clearly versus a speaker who lacks the necessary vocabulary and fails to enunciate. Ethos can also be influenced by nonverbal factors as well, such as posture, body language, eye contact, and even the speaker’s choice of clothing. For example, a military officer proudly wearing their uniform bedecked with medals will go a long way to establishing ethos without them saying a single word.

Here as a simple example of ethos :

• “As a former mayor of this city, I believe we can solve this crisis if we band together.”

The speaker uses ethos by alerting the audience of their credentials and experience. By doing so, they rely on their reputation to be more persuasive. This “as a…” method of establishing ethos is common, and you have probably seen it used in many persuasive advertisements and speeches.

What is pathos ?

In Greek, pathos literally translates to “suffering, experience, or sensation.” The word pathos is related to the words pathetic , sympathy , and empathy , which all have to do with emotions or emotional connections. Aristotle used the word pathos to refer to the emotional impact that an argument had on an audience; this usage is still mainly how pathos is used in rhetoric today.

As a rhetorical appeal, pathos is referred to as “the appeal to emotion.” Generally speaking, an author or speaker is using pathos when they are trying to persuade an audience by causing some kind of emotional reaction. When it comes to pathos , any and all emotions are on the table: sadness, fear, hope, joy, anger, lust, pity, etc.

As you probably know from your own life, emotions are a powerful motivating factor. For this reason, relying on pathos is often a smart and effective strategy for persuading an audience. Both positive and negative emotions can heavily influence an audience: for example, an audience will want to support a speaker whose position will make them happy, a speaker who wants to end their sadness, or a speaker who is opposed to something that makes them angry.

Here is a simple example of pathos :

• “Every day, the rainforests shrink and innocent animals are killed. We must do something about this calamitous trend before the planet we call our home is damaged beyond repair.”

Here, the author is trying to win over an audience by making them feel sad, concerned, or afraid. The author’s choice of words like “innocent” and “calamitous” enforce the fact that they are trying to rely on pathos .

What is logos ?

In Greek, the word logos literally translates to “word, reason, or discourse.” The word logos is related to many different words that have to do with reason, discourse, or knowledge, such as logic , logical , and any words that end in the suffixes -logy or -logue .

As a mode of persuasion and rhetorical appeal, logos is often referred to as “the appeal to reason.” If a speaker or author is relying on logos , they are typically reciting facts or providing data and statistics that support their argument. In a manner of speaking, logos does away with all of the bells and whistles of ethos and pathos and cuts to the chase by trying to present a rational argument.

Logos can be effective in arguments because, in theory, it is impossible to argue against truth and facts. An audience is more likely to agree with a speaker who can provide strong, factual evidence that shows their position is correct. On the flip side, an audience is less likely to support an argument that is flawed or entirely wrong. Going further, a speaker that presents a lot of supporting evidence and data to the audience is likely to come across as knowledgeable and someone to be listened to, which earns bonus points in ethos as well.

While Aristotle clearly valued an argument based on reason very highly, we know that logos alone doesn’t always effectively persuade an audience. In your own life, you have likely seen a rational, correct speaker lose an argument to a charismatic, authoritative speaker who may not have the facts right.

Here is a simple example of logos :

• “According to market research, sales of computer chips have increased by 300% in the last five years. Analysis of the industry tells us that the market share of computer chips is dominated by Asian manufacturers. It is clear that the Asian technology sector will continue to experience rapid growth for the foreseeable future.”

In this paragraph, the author is using data, statistics, and logical reasoning to make their argument. They clearly hope to use logos to try to convince an audience to agree with them.

Do you need persuading to take this quiz on identifying ethos, pathos, and logos? We think you’ll be a champion at it.

Examples of ethos , pathos , and logos

Ethos , pathos , and logos can all be employed to deliver compelling and persuasive arguments or to win over an audience. Let’s look at a variety of examples to see how different speakers and authors have turned to these modes of persuasion over the years.

“Come I to speak in Caesar’s funeral. He was my friend, faithful and just to me […] You all did see that on the Lupercal I thrice presented him a kingly crown, Which he did thrice refuse: was this ambition?” —Marc Antony, Julius Caesar by William Shakespeare

In this scene, Marc Antony is trying to win over the Roman people, so Shakespeare has Antony rely on ethos . Antony is establishing himself as both a person of authority in Rome (having the power to offer Caesar a crown) and an expert on Caesar’s true character (Antony was Caesar’s close friend and advisor).

“During the next five years, I started a company named NeXT, another company named Pixar, and fell in love with an amazing woman who would become my wife. Pixar went on to create the world’s first computer animated feature film, Toy Story , and is now the most successful animation studio in the world. In a remarkable turn of events, Apple bought NeXT, I returned to Apple, and the technology we developed at NeXT is at the heart of Apple’s current renaissance.” —Steve Jobs, 2005

Here, Steve Jobs is providing his background–via humblebrag – of being a major figure in several different highly successful tech companies. Jobs is using ethos to provide substance to his words and make it clear to the audience that he knows what he is talking about and they should listen to him.

“Moreover, though you hate both him and his gifts with all your heart, yet pity the rest of the Achaeans who are being harassed in all their host; they will honour you as a god, and you will earn great glory at their hands. You might even kill Hector; he will come within your reach, for he is infatuated, and declares that not a Danaan whom the ships have brought can hold his own against him.” —Ulysses to Achilles, The Iliad by Homer

In this plea, Ulysses is doing his best to pile on the pathos . In one paragraph, Ulysses is attempting to appeal to several of Achilles’s emotions: his hatred of Hector, his infamous stubborn pride, his sympathy for civilians, and his desire for vengeance.

“I am not unmindful that some of you have come here out of great trials and tribulations. Some of you have come fresh from narrow jail cells. Some of you have come from areas where your quest—quest for freedom left you battered by the storms of persecution and staggered by the winds of police brutality.” —Dr. Martin Luther King Jr., 1963

In this excerpt from his “I Have A Dream” speech, King is using pathos to accomplish two goals at once. First, he is connecting with his audience by making it clear is aware of their plight and suffering. Second, he is citing these examples to cause sadness or outrage in the audience. Both of these effects will make an audience interested in what he has to say and more likely to support his position.

Dr. King’s “I Have A Dream” speech is recognizable and noteworthy for many reasons, including the rhetorical device he employs. Learn about it here.

“Let it be remembered how powerful the influence of a single introduced tree or mammal has been shown to be. But in the case of an island, or of a country partly surrounded by barriers, into which new and better adapted forms could not freely enter, we should then have places in the economy of nature which would assuredly be better filled up if some of the original inhabitants were in some manner modified; for, had the area been open to immigration, these same places would have been seized on by intruders. In such case, every slight modification, which in the course of ages chanced to arise, and which in any way favoured the individuals of any of the species, by better adapting them to their altered conditions, would tend to be preserved; and natural selection would have free scope for the work of improvement.” —Charles Darwin, On the Origin of the Species , 1859

In this passage, Darwin is using logos by presenting a rational argument in support of natural selection. Darwin connects natural selection to established scientific knowledge to argue that it makes logical sense that animals would adapt to better survive in their environment.

“I often echo the point made by the climate scientist James Hansen: The accumulation of carbon dioxide, methane and other greenhouse gases—some of which will envelop the planet for hundreds and possibly thousands of years—is now trapping as much extra energy daily as 500,000 Hiroshima-class atomic bombs would release every 24 hours. This is the crisis we face.” —Al Gore, “The Climate Crisis Is the Battle of Our Time, and We Can Win,” 2019

In this call to action, Al Gore uses logos to attempt to convince his audience of the significance of climate change. In order to do this, Gore both cites an expert in the field and provides a scientifically accurate simile to explain the scale of the effect that greenhouse gases have on Earth’s atmosphere.

What are mythos and kairos ?

Some modern scholars may also use terms mythos and kairos when discussing modes of persuasion or rhetoric in general.

Aristotle used the term mythos to refer to the plot or story structure of Greek tragedies, i.e., how a playwright ordered the events of the story to affect the audience. Today, mythos is most often discussed as a literary or poetic term rather than a rhetorical one. However, mythos may rarely be referred to as the “appeal to culture” or the “appeal to myth” if it is treated as an additional mode of persuasion. According to this viewpoint, a speaker/writer is using mythos if they try to persuade an audience using shared cultural customs or societal values.

A commonly cited example of mythos is King’s “I Have a Dream” speech quoted earlier. King says:

“When the architects of our republic wrote the magnificent words of the Constitution and the Declaration of Independence, they were signing a promissory note to which every American was to fall heir. This note was a promise that all men—yes, black men as well as white men—would be guaranteed the ‘unalienable rights’ of ‘life, liberty and the pursuit of happiness.’ ”

Throughout the speech, King repeatedly uses American symbols and American history ( mythos ) to argue that all Americans should be outraged that Black Americans have been denied freedom and civil rights.

Some modern scholars may also consider kairos as an additional mode of persuasion. Kairos is usually defined as referring to the specific time and place that a speaker chooses to deliver their speech. For written rhetoric, the “place” instead refers to the specific medium or publication in which a piece of writing appears.

Unlike the other modes of persuasion, kairos relates to the context of a speech and how the appropriateness (or not) of a setting affects how effective a speaker is. Once again, King’s “I Have a Dream” speech is a great example of the use of kairos . This speech was delivered at the steps of the Lincoln Memorial during the 100th anniversary of the Emancipation Proclamation at the end of the March on Washington for Jobs and Freedom. Clearly, King intended to use kairos to enhance the importance and timeliness of this landmark speech.

What Are Logos, Pathos & Ethos?

By: Derek Jansen (MBA) | Reviewer: Eunice Rautenbach (DTech) | June 2023

I f you spend any amount of time exploring the wonderful world of philosophy, you’re bound to run into the dynamic trio of rhetorical appeals: logos , ethos and pathos . But, what exactly do they mean and how can you use them in your writing or speaking? In this post, we’ll unpack the rhetorical love triangle in simple terms, using loads of practical examples along the way.

Overview: The Rhetorical Triangle

• What are logos , pathos and ethos ?
• Logos unpacked (+ examples)
• Pathos unpacked (+ examples)
• Ethos unpacked (+ examples)
• The rhetorical triangle

What are logos, ethos and pathos?

Simply put, logos, ethos and pathos are three powerful tools that you can use to persuade an audience of your argument . At the most basic level, logos appeals to logic and reason, while pathos appeals to emotions and ethos emphasises credibility or authority.

Naturally, a combination of all three rhetorical appeals packs the biggest punch, but it’s important to consider a few different factors to determine the best mix for any given context. Let’s look at each rhetorical appeal in a little more detail to understand how best to use them to your advantage.

Logos appeals to the logical, reason-driven side of our minds. Using logos in an argument typically means presenting a strong body of evidence and   facts to support your position. This evidence should then be accompanied by sound logic and well-articulated reasoning .

Let’s look at some examples of logos in action:

• A friend trying to persuade you to eat healthier might present scientific studies that show the benefits of a balanced diet and explain how certain nutrients contribute to overall health and longevity.
• A scientist giving a presentation on climate change might use data from reputable studies, along with well-presented graphs and statistical analyses to demonstrate the rising global temperatures and their impact on the environment.
• An advertisement for a new smartphone might highlight its technological features, such as a faster processor, longer battery life, and a high-resolution camera. This could also be accompanied by technical specifications and comparisons with competitors’ models.

In short, logos is all about using evidence , logic and reason to build a strong argument that will win over an audience on the basis of its objective merit . This contrasts quite sharply against pathos, which we’ll look at next.

Contrasted to logos, pathos appeals to the softer side of us mushy humans. Specifically, it focuses on evoking feelings and emotions in the audience. When utilising pathos in an argument, the aim is to cultivate some feeling of connection in the audience toward either yourself or the point that you’re trying to make.

In practical terms, pathos often uses storytelling , vivid language and personal anecdotes to tap into the audience’s emotions. Unlike logos, the focus here is not on facts and figures, but rather on psychological affect . Simply put, pathos utilises our shared humanness to foster agreement.

Let’s look at some examples of pathos in action:

• An advertisement for a charity might incorporate images of starving children and highlight their desperate living conditions to evoke sympathy, compassion and, ultimately, donations.
• A politician on the campaign trail might appeal to feelings of hope, unity, and patriotism to rally supporters and motivate them to vote for his or her party.
• A fundraising event may include a heartfelt personal story shared by a cancer survivor, with the aim of evoking empathy and encouraging donations to support cancer research.

As you can see, pathos is all about appealing to the human side of us – playing on our emotions to create buy-in and agreement.

Last but not least, we’ve got ethos. Ethos is all about emphasising the credibility and authority of the person making the argument, or leveraging off of someone else’s credibility to support your own argument.

The ethos card can be played by highlighting expertise, achievements, qualifications and accreditations , or even personal and professional associations and connections. Ultimately, the aim here is to foster some level of trust within the audience by demonstrating your competence, as this will make them more likely to take your word as fact.

Let’s look at some examples of ethos in action:

• A fitness equipment brand might hire a well-known athlete to endorse their product.
• A toothpaste brand might make claims highlighting that a large percentage of dentists recommend their product.
• A financial advisor might present their qualifications, certifications and professional memberships when meeting with a prospective client.

As you can see, using ethos in an argument is largely about emphasising the credibility of the person rather than the logical soundness of the argument itself (which would reflect a logos-based approach). This is particularly helpful when there isn’t a large body of evidence to support the argument.

Ethos can also overlap somewhat with pathos in that positive emotions and feelings toward a specific person can oftentimes be extended to someone else’s argument. For example, a brand that has nothing to do with sports could still benefit from the endorsement of a well-loved athlete, just because people feel positive feelings about the athlete – not because of that athlete’s expertise  in the product they’re endorsing.

How to use logos, pathos and ethos

Logos, pathos and ethos combine to form the rhetorical triangle , also known as the Aristotelian triangle. As you’d expect, the three sides (or corners) of the triangle reflect the three appeals, but there’s also another layer of meaning. Specifically, the three sides symbolise the relationship between the speaker , the audience and the message .

Without getting too philosophical, the key takeaway here is that logos, pathos and ethos are all tools that you can use to present a persuasive argument . However, how much you use each tool needs to be informed by careful consideration of who your audience is and what message you’re trying to convey to them.

For example, if you’re writing a research paper for a largely scientific audience, you’ll likely lean more heavily on the logos . Conversely, if you’re presenting a speech in which you argue for greater social justice, you may lean more heavily on the pathos to win over the hearts and minds of your audience.

Simply put, by understanding the relationship between yourself (as the person making the argument), your audience , and your message , you can strategically employ the three rhetorical appeals to persuade, engage, and connect with your audience more effectively in any context. Use these tools wisely and you’ll quickly notice what a difference they can make to your ability to communicate and more importantly, to persuade .

6 Rhetorical Appeals: Logos, Pathos, and Ethos Defined

By melanie gagich and emilie zickel.

Rhetoric is the way that authors use and manipulate language in order to persuade an audience. Once we understand the rhetorical situation out of which a text is created (why it was written, for whom it was written, by whom it was written, how the medium in which it was written creates certain constraints or perhaps freedoms of expression), we can look at how all of those contextual elements shape the author’s creation of the text .

We can look first at the classical rhetorical appeals, which are the three ways to classify authors’ intellectual, moral, and emotional approaches to getting the audience to have the reaction that the author hopes for.

Rhetorical Appeals

Rhetorical appeals refer to ethos, pathos, and logos. These are classical Greek terms, dating back to Aristotle, who is traditionally seen as the father of rhetoric. To be rhetorically effective (and thus persuasive), an author must engage the audience in a variety of compelling ways, which involves carefully choosing how to craft their argument so that the outcome, audience agreement with the argument or point, is achieved. Aristotle defined these modes of engagement and gave them the terms that we still use today: logos, pathos, and ethos.

Logos: Appeal to Logic

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

When an author relies on logos, it means that they are using logic, careful structure, and objective evidence to appeal to the audience. An author can appeal to an audience’s intellect by using information that can be fact checked (using multiple sources ) and thorough explanations to support key points. Additionally, providing a solid and non-biased explanation of one’s argument is a great way for an author to invoke logos.

For example, if I were trying to convince my students to complete their homework, I might explain that I understand everyone is busy and they have other classes (non-biased), but the homework will help them get a better grade on their test (explanation). I could add to this explanation by providing statistics showing the number of students who failed and didn’t complete their homework versus the number of students who passed and did complete their homework (factual evidence).

Logical appeals rest on rational modes of thinking , such as

• Comparison –  including a comparison between one thing (with regard to your topic ) and 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 –  arguing 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 – starting with a broad, general claim /example and using it to support a more specific point or claim
• Inductive reasoning –  using several specific examples or cases to make a broad generalization
• Exemplification –  using many examples or a variety of evidence to support a single point
• Elaboration – moving beyond just including a fact but explaining the significance or relevance of that fact
• Coherent thought – maintaining a well-organized line of reasoning; not repeating ideas or jumping around

Pathos: Appeal to Emotions

When an author relies on pathos, it means that they are trying to tap into the audience’s emotions to get them to agree with the author’s claim . An author using pathetic appeals wants the audience to feel something: anger, pride, joy, rage, or happiness.  For example, many of us have seen the ASPCA commercials that use photographs of injured puppies or sad-looking kittens and slow, depressing music to emotionally persuade their audience to donate money.

Pathos-based rhetorical strategies are any strategies that get the audience to “open up” to the topic , the argument, or the author. Emotions can make us vulnerable, and an author can use this vulnerability to get the audience to believe that their argument is a compelling one.

Pathetic appeals might include

• Expressive descriptions of people, places, or events that help the reader to feel or experience those events
• Vivid imagery  of people, places, or events that help the reader to feel like they are seeing those events
• Personal stories that make the reader feel a connection to, or empathy for, the person being described
• Emotion-laden   vocabulary  as a way to put the reader into that specific emotional mindset (What is the author trying to make the audience feel? And how are they doing that?)
• 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.

When reading a text , try to locate when the author is trying to convince the reader using emotions because, if used to excess, pathetic appeals can indicate a lack of substance or emotional manipulation of the audience. See the links below about fallacious pathos for more information.

Ethos: Appeal to Values/Trust

Ethical appeals have two facets: audience values and authorial credibility/character.

On the one hand, when an author makes an ethical appeal, they are attempting to  tap into the values or ideologies  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. When an author evokes the values that the audience cares about to justify or support their argument, we classify that as ethos. The audience will feel that the author is making an argument that is “right” (in the sense of moral “right”-ness, i.e., “My argument rests upon the values that matter to you. Therefore, you should accept my argument”). This first part of the definition of ethos, then, is focused on the audience’s values.

On the other hand, this sense of referencing what is “right” in an ethical appeal connects to the other sense of ethos: the author. Ethos that is centered on the author revolves around two concepts: the credibility of the author and their character.

• Credibility of the speaker/author is determined by their knowledge and expertise in the subject at hand. For example, if you are learning about Einstein’s Theory of Relativity, would you rather learn from a professor of physics or a cousin who took two science classes in high school 30 years ago? It is fair to say that, in general, the professor of physics would have more credibility to discuss the topic of physics. To establish their credibility, an author may draw attention to who they are or what kinds of experience they have with the topic being discussed as an ethical appeal (i.e., “Because I have experience with this topic –and I know my stuff– you should trust what I am saying about this topic ”). Some authors do not have to establish their credibility because the audience already knows who they are and that they are credible.
• Character is another aspect of ethos. Character   is different from credibility because it involves personal history and even personality traits. A person can be credible but lack character or vice versa. For example, in politics, sometimes the most experienced candidates–those who might be the most credible candidates–fail to win elections because voters do not accept their character. Politicians take pains to shape their character as leaders who have the interests of the voters at heart. The candidate who successfully proves to the voters (the audience) that they have the type of character that the audience can trust is more likely to win.

Thus, ethos comes down to trust. How can the author gain the audience’s trust so that the audience will accept their argument? How can the author make him or herself appear as a credible speaker who embodies the character traits that the audience values? In building ethical appeals, we see authors referring either directly or indirectly to the values that matter to the intended audience (so that the audience will trust the speaker). Authors use language, phrasing, imagery, or other writing styles common to people who hold those values, thereby “talking the talk” of people with those values (again, so that the audience is inclined to trust the speaker). Authors refer to their experience and/or authority with the topic as well (and therefore demonstrate their credibility).

When reading, you should think about the author’s credibility regarding the subject as well as their character. Here is an example of a rhetorical move that connects with ethos: when reading an article about abortion, the author mentions that she has had an abortion. That is an example of an ethical move because the author is creating credibility via anecdotal evidence and first-person narrative. In a rhetorical analysis project, it would be up to you, the analyzer, to point out this move and associate it with a rhetorical strategy.

Rhetorical Appeals Misuse

When writers misuse logos, pathos, or ethos, arguments can be weakened. Above, we defined and described what logos, pathos, and ethos are and why authors may use those strategies. Sometimes, using a combination of logical, pathetic, and ethical appeals leads to a sound, balanced, and persuasive argument. It is important to understand, though, that using rhetorical appeals does not always lead to a sound, balanced argument. In fact, any of the appeals could be misused or overused. And when that happens, arguments can be weakened.

Rhetorical Appeals

Rhetoric is the way that authors use and manipulate language to persuade an audience. Once we understand the rhetorical situation in which a text is created (why it was written, for whom it was written, by whom it was written, how the medium in which it was written creates certain constraints, or perhaps freedom of expression), we can look at how all of those contextual elements shape the author’s creation of the text.

We can look first at the classical rhetorical appeals, which are the three ways to classify an author’s intellectual, moral, and emotional approaches to getting the audience to react in the manner in which the author may have intended.

In composition studies, the term rhetorical appeals refers to the use of ethos, pathos, and logos. These are classical Greek terms dating back to Aristotle who is traditionally viewed as the creator of rhetoric. To be rhetorically effective (and thus persuasive), an author must engage the audience in a variety of compelling ways which involves carefully choosing how to craft their argument so that the intended outcome is achieved. Often that outcome occurs when the audience agrees with the argument or point being presented. Aristotle defined these modes of engagement and gave them the terms that we still use today: logos, pathos, and ethos.

Logos: Appeal to Logic

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

When an author relies on logos, it means that they are using logic, careful structure, and objective evidence to appeal to the audience. Objective evidence is anything that can be proven with statistics or other facts via more than one source. Oftentimes that evidence has been validated by more than one authority in the field of study.

For example, if Dr. Smith was trying to convince her students to complete their homework, she might explain that she understands everyone is busy and they have other classes (non-biased) but that completing their homework will help them get a better grade on their test (explanation). She could add to this explanation by providing statistics showing the number of students who failed and didn’t complete their homework versus the number of students who passed and did complete their homework (factual evidence). This is an example of logos employed for the purposes of argument and persuasion.

Logical appeals rest on rational modes of thinking ,  such as:

• Comparison: a comparison between one thing (with regard to your topic) and 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:  starting with a broad, general claim/example and using it to support a more specific point or claim (picture an hourglass where the sands gather in the middle)
• Inductive reasoning: using several specific examples or cases to make a broad generalization (consider the old question “if your friend jumped off of a bridge, would you” to make the sweeping claim that all young people are easily persuaded to follow the crowd)
• Analogical reasoning:  moves from one particular claim/example to another, seemingly sequential (sometimes this line of reasoning is used to make a guilt-by-association claim)
• Exemplification:  use of many examples or a variety of evidence to support a single point
• Elaboration: moving beyond just including a fact but explaining the significance or relevance of that fact
• Coherent thought:  maintaining a well-organized line of reasoning, not repeating ideas or jumping around

Pathos: Appeal to Emotions

When an author relies on pathos, it means that they are trying to tap into the audience’s emotions to get them to agree with the author’s claim. An author using pathos appeals wants the audience to feel something: anger, pride, joy, rage, or happiness. For example, many of us have seen the ASPCA commercials that use photographs of injured puppies or sad-looking kittens and slow, depressing music to emotionally persuade their audience to donate money. This is a classic example of the use of pathos in argument.

Pathos-based rhetorical strategies are any strategies that get the audience to “open up” to the topic, the argument, or the author through an emotional connection. Emotions can make us vulnerable, and an author can use this vulnerability to make the audience believe that their argument is compelling.

Pathos appeals might include:

• Expressive descriptions of people, places, or events that help the reader to feel or experience those events
• Vivid imagery of people, places, or events that help the reader to feel like they are seeing those events
• Sharing personal stories that make the reader feel a connection to, or empathy for, the person being described
• Using emotion-laden vocabulary as a way to put the reader into that specific emotional mindset (what is the author trying to make the audience feel? and how are they doing that?)
• Using 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 a connection to or rejection of the person/group/event being discussed.

When reading a text, try to locate where the author is trying to convince the reader by strictly using emotions. Pathos appeals can indicate a lack of substance or emotional manipulation of the audience if used to excess. If the only way an author can persuade the reader is by making them sad or angry, does that make for a solid, valid argument?

Ethos: Appeal to Values/Trust

Appeals using ethos are typically two-faceted, focusing on audience values and authorial credibility/character.

On the one hand, when an author makes an ethical appeal, they are attempting to  tap into the values or ideologies that the audience holds. Examples include 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. When an author evokes the values that the audience cares about as a way to justify or support their argument, we classify that as ethos. The audience will feel that the author is making an argument that is “right” (in the sense of moral “right” -ness, i.e., My argument rests upon the values that matter to you. Therefore, you should accept my argument ). This first part of the definition of ethos, then, is focused on the audience’s values.

On the other hand, this sense of referencing what is “right” in an ethical appeal connects to the other sense of ethos, the author. Ethos that is centered on the author revolves around two concepts: the credibility of the author and their character.

Credibility  of the speaker/author is determined by their knowledge and expertise in the subject at hand. For example, if you are learning about Einstein’s Theory of Relativity, would you rather learn from a professor of physics or a cousin who took two science classes in high school thirty years ago? It is fair to say that, in general, the professor of physics would have more credibility to discuss the topic of physics than your cousin. To establish their credibility, an author may draw attention to who they are or what kinds of experience they have with the topic being discussed as an ethical appeal (i.e.,  Because I have experience with this topic – and I know my stuff! – you should trust what I am saying about this topic ). Some authors do not have to establish their credibility because the audience already knows who they are and that they are credible.

Character is another aspect of ethos that is different from credibility because it involves personal history and sometimes personality traits. A person can be credible but lack character, or vice versa. For example, in politics, sometimes the most experienced candidates – those who might be the most credible candidates – fail to win elections because voters do not accept their character. Politicians take pains to shape their character as leaders who have the interests of the voters at heart. The candidate who successfully proves to the voters (the audience) that they have the type of character that they can trust is more likely to win.

Thus, ethos comes down to trust. How can the author get the audience to trust them so that they will accept their argument? How can the author make themselves appear as a credible speaker who embodies the character traits that the audience values?

In building ethical appeals, we may see authors:

• Referring either directly or indirectly to the values that matter to the intended audience (so that the audience will trust the speaker)
• Using language, phrasing, imagery, or other writing styles common to people who hold those values, thereby “talking the talk” of people with those values (again, so that the audience is inclined to trust the speaker)
• Referring to their experience and/or authority with the topic (and therefore demonstrating their credibility)
• Referring to their own character or making an effort to build their character in the text

When reading, you should always think about the author’s credibility regarding the subject as well as their character. Here is an example of a rhetorical move that connects with ethos: when reading an article about abortion, the author mentions that they have had an abortion. That is an example of an ethical move because the author is creating credibility via anecdotal evidence and first-person narrative. In a rhetorical analysis project, it would be up to you, the analyzer, to point out this move and associate it with a rhetorical strategy.

When Writers Misuse Logos, Pathos, or Ethos, Arguments can be Weakened

Above, we defined and described what logos, pathos, and ethos are and why authors may use those strategies. Sometimes, using a combination of appeals leads to a sound, balanced, and persuasive argument. It is important to understand, though, that using rhetorical appeals does not always lead to a sound, balanced argument. In fact, any of the appeals could be misused or overused. When that happens, arguments can be weakened.
