Getting Started
This topic introduces the foundational tools of persuasion that have been studied for thousands of years: ethos, pathos, and logos. Understanding these rhetorical appeals is essential for moving beyond simply identifying what a writer is saying to analyzing how they are saying it. This skill solves a common problem for students: it provides a precise vocabulary for explaining the specific ways a writer attempts to influence an audience’s thoughts, feelings, and actions.
What You Should Be Able to Do
Identify a writer’s central claims and the specific evidence used to support them.
Describe how a writer appeals to an audience’s sense of trust (ethos), emotions (pathos), and logic (logos).
Explain the connection between a writer’s specific choices—such as their tone or type of evidence—and the intended persuasive effect.
Analyze how the rhetorical situation (the writer, audience, context, and purpose) influences a writer’s use of the appeals.
Key Moves and Effects
The dominant lens for this unit is Rhetorical Analysis. Your goal is to investigate and explain the strategic choices a writer makes to achieve a purpose with a specific audience. The rhetorical appeals are some of the most powerful and common choices you will analyze.
Situation and Purpose
Every text is a response to a specific rhetorical situation, which includes the writer, the audience, the context, the purpose, and the exigence (the impetus for writing). A writer’s strategic choices, especially their use of ethos, pathos, and logos, are directly informed by this situation. For example, a scientist writing in a peer-reviewed journal will rely heavily on logos and ethos to establish credibility with an expert audience, while a charity writing a fundraising letter will lean on pathos to inspire empathy and action from a general audience. Always ask: Given the situation, why was this particular appeal the right choice?
Strategies You Might Notice and Why They Work
Writers don't simply state, "Here is my ethos." Instead, they build appeals through specific choices in language and evidence. As you read, look for these common moves:
To Build Ethos (Appeal to Credibility and Trust): Writers establish ethos to show they are knowledgeable, fair, and trustworthy.
Moves: Mentioning their credentials or experience, using a formal and respectful tone, citing credible sources, or acknowledging and fairly representing counterarguments.
Effect: When an audience trusts a writer, they are more likely to accept their claims. Ethos makes the writer seem like a reliable guide on the subject.
To Build Pathos (Appeal to Emotion): Writers use pathos to create an emotional connection with the audience, making an issue feel more urgent, personal, or important.
Moves: Using vivid, sensory details; sharing a personal story (anecdote); using words with strong positive or negative connotations (diction); or employing figurative language like metaphors.
Effect: Pathos can motivate an audience to act. By evoking emotions like anger, hope, guilt, or pride, a writer can bypass purely logical consideration to create a powerful, immediate bond with the reader.
To Build Logos (Appeal to Logic): Writers use logos to show that their argument is well-reasoned and supported by facts.
- Moves: Providing verifiable facts, citing statistics and data, using logical structures like cause-and-effect or comparison-contrast, or constructing a clear line of reasoning with a main claim and supporting points.
- Effect: Logos makes an argument feel objective and undeniable. It appeals to the audience's intellect and persuades them that the writer's conclusion is not just an opinion, but a rational outcome of the evidence.
Commentary Explaining How Evidence Supports Purpose and Effect
The most critical part of rhetorical analysis is your commentary—the explanation of how and why a writer's choice works. It’s not enough to identify a strategy; you must connect it to an effect on the audience and the writer’s overall purpose.
A simple frame for commentary:
"By [making a specific choice], the writer builds [ethos/pathos/logos] to [achieve a specific effect on the audience], which ultimately helps them [accomplish their overall purpose]."
Example:
"By opening with a personal story about his own family’s struggles, the writer appeals to pathos, inviting the audience to feel empathy and see the issue on a human level. This emotional connection makes the audience more receptive to the logical policy proposals that follow, supporting his overall purpose of gaining support for the new law."
Data and Organization Tools
When analyzing a text, you need a way to organize your observations. A Device–Effect Matrix helps you systematically track a writer's choices and connect them to their function and impact.
Device–Effect Matrix
| Rhetorical Choice | Where It Appears (Quote/Paraphrase) | Primary Appeal(s) | Effect on Audience |
|---|---|---|---|
| Use of a statistic | "According to the report, over 70% of participants..." | Logos | Lends factual weight to the claim; makes the argument seem objective and hard to dispute. |
| Personal anecdote | "I remember when my grandfather told me..." | Pathos, Ethos | Creates an emotional connection; makes the writer seem relatable and trustworthy. |
| Citing an expert | "As Dr. Evelyn Reed, a leading researcher, notes..." | Ethos, Logos | Borrows the credibility of the expert; suggests the claim is supported by authoritative evidence. |
| Emotionally charged diction | Describing a situation as "a devastating crisis" instead of "a problem." | Pathos | Evokes a sense of urgency and alarm, motivating the audience to see the issue as critical. |
Device and Evidence Bank
Here are some of the fundamental terms you will use to describe and analyze arguments.
Claim: A writer’s main point or assertion that they are trying to prove. A claim must be arguable, not a simple statement of fact.
Evidence: The information, facts, data, or stories a writer uses to support their claim. The type of evidence often determines the type of appeal.
Ethos: A rhetorical appeal that focuses on the character, credibility, or authority of the writer. It answers the audience's question: "Why should I trust you?"
Pathos: A rhetorical appeal to the audience’s emotions, values, or beliefs. It seeks to make the audience feel a certain way about the subject.
Logos: A rhetorical appeal to logic and reason. It uses evidence and clear reasoning to construct a sound argument.
Anecdote: A brief personal story used to illustrate a point or connect with the audience on an emotional level.
Statistic: Numerical data used as evidence to support a claim, often appealing to logos.
Expert Testimony: Citing the words or findings of a person with recognized credentials or expertise on a subject to build ethos and logos.
Diction: A writer's specific word choice. Words with strong connotations can be a powerful tool for creating pathos.
Tone: The writer's attitude toward the subject or audience, conveyed through their language. Tone is a key way writers establish ethos.
Skill Snapshots
This section provides brief examples of how to connect a writer's strategy to its persuasive effect.
Rhetorical Analysis
Strategy: A writer begins an article on environmental policy by mentioning her 20 years of experience as a field biologist.
Effect: This immediately establishes ethos. The audience is more likely to trust her claims because she presents herself as a knowledgeable and experienced authority on the topic.
Strategy: In an argument against animal testing, a writer includes a detailed, vivid description of a single animal's suffering.
Effect: This appeals to pathos by moving beyond abstract arguments to create a powerful emotional response of sympathy and outrage in the reader, making them more invested in the writer's cause.
Strategy: To argue for a new traffic light, a speaker presents a chart showing the number of accidents at an intersection has doubled in the last five years.
Effect: This is a direct appeal to logos. The clear, quantifiable data provides logical and compelling proof that a problem exists, making the proposed solution seem rational and necessary.
Common Misconceptions and Clarifications
Misconception: A piece of writing uses only one appeal.
- Clarification: Most effective arguments skillfully blend ethos, pathos, and logos. A single sentence can even appeal to multiple modes at once. For instance, citing a statistic about child poverty appeals to logos (the data) and pathos (the emotional weight of the topic).
Misconception: Identifying the appeal is the same as analyzing it.
- Clarification: Naming the appeal is just the first step. True analysis requires you to explain how the writer’s specific choice creates the appeal and why that appeal is effective for achieving their purpose with their specific audience.
Misconception: Pathos is just about making the audience feel sad.
- Clarification: Pathos encompasses the full spectrum of human emotion. A writer can appeal to joy, pride, fear, anger, hope, or nostalgia to connect with an audience and advance an argument.
Misconception: Logos only involves numbers and statistics.
- Clarification: Logos is the appeal to reason in all its forms. While data is one form of logos, so are clear lines of reasoning, if-then constructions, cause-and-effect explanations, and well-supported analogies.
Summary
The rhetorical appeals—ethos, pathos, and logos—are the essential building blocks of persuasion. A writer makes deliberate choices about their tone, evidence, and language to build these appeals and connect with an audience. As an analyst, your job is to identify these choices, name the appeals they create, and, most importantly, explain how these strategies work together to help the writer achieve their purpose. Mastering this skill will allow you to deconstruct any argument and understand the intricate craft behind effective communication.
