3.5 Rhetorical Appeals: Logos, Pathos, and Ethos Defined

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. 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 of “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

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 to the author through an emotional connection. 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.

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 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 because, if used to excess, pathos appeals can indicate a lack of substance or emotional manipulation of the audience. If the only way in which an author can persuade the reader is by making him/her sad or angry, does that make for a solid, valid argument?

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 him or her so that they will accept their argument? How can the author make himself or herself 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 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.
