Difficulty: Intermediate | Prerequisites: basic familiarity with persuasive writing and the three classical appeals (ethos, pathos, logos).
This unit sits at the intersection of American history and rhetorical analysis. You are expected to read historical speeches, identify the persuasive strategies each speaker uses, and evaluate how well those strategies serve the speaker's purpose. If you are comfortable spotting a thesis statement and know the difference between an emotional appeal and a logical one, you are ready. The broader goal is to understand how language has been used to shape civil rights legislation and constitutional amendments.
Rhetorical analysis means breaking a speech into its persuasive parts: the central idea, the evidence behind it, the emotional or logical appeal chosen, and the specific devices (repetition, antithesis, etc.) the speaker deploys. This unit uses two civil rights-era speeches, Lyndon B. Johnson's address to Congress on voting rights and Shirley Chisholm's argument for the Equal Rights Amendment, as case studies. The exam tests whether you can identify these elements, give accurate examples, and explain why each choice suits the speaker's purpose.
Central idea
The single overarching claim or argument a speech makes. Think of it as the one sentence you would use to tell someone what the speech is about.
Supporting details
Facts, examples, statistics, or historical references a speaker uses to back up the central idea. In simple terms, these are the receipts.
Rhetorical appeal
A category of persuasion drawn from Aristotle's framework. The three appeals are ethos (credibility), pathos (emotion), and logos (logic/evidence). Think of it as the broad strategy a speaker picks to win the audience over.
Pathos
An appeal to the audience's emotions: fear, sympathy, moral outrage, hope. In simple terms, the speaker is trying to make you feel something so strongly that you act.
Logos
An appeal to logic and evidence: statistics, case law, cause-and-effect reasoning. In simple terms, the speaker is building an argument you cannot poke holes in.
Ethos
An appeal to the speaker's own credibility, character, or authority. In simple terms, the speaker is saying "trust me, I know what I am talking about."
Rhetorical device
A specific technique of language (not the broad appeal category) that makes an argument more memorable or persuasive. Devices include repetition, antithesis, parallelism, rhetorical questions, and many others.
Repetition
Deliberate reuse of a word or phrase for emphasis. Think of it as a drumbeat that drives a single idea home. Johnson's "We shall overcome" is the textbook example here.
Antithesis
Placing two opposing ideas side by side in a balanced structure to highlight a contrast. In simple terms, the speaker holds up what should be true next to what actually is true, and the gap does the persuading. Chisholm's "We proclaim equality, yet deny it to half our citizens" is the example to remember.
Oration
Formal public speaking, especially a speech intended to persuade or inspire. In simple terms, it is a speech with stakes.
Every speech analysis in this unit follows the same four-part framework:
Central idea: state it in one sentence. If you cannot, you have not found it yet.
Supporting details: identify 2-3 pieces of evidence (facts, historical references, statistics) the speaker uses to develop that central idea.
Rhetorical appeal: name the dominant appeal (pathos, logos, or ethos) and give a direct quotation that illustrates it. Then explain in one sentence why that appeal suits the speaker's purpose.
Rhetorical device: name a specific device (repetition, antithesis, parallelism, etc.), quote the passage where it appears, and explain how it strengthens the central idea.
Central idea: Voting rights are essential to establishing true equality and justice in America.
Supporting details:
Johnson frames voting rights as both a moral imperative and a historical debt, especially to African Americans who faced structural disenfranchisement.
He names specific discriminatory mechanisms: literacy tests and poll taxes.
He argues the federal government has a responsibility to intervene.
Rhetorical appeal (pathos): Johnson says, "It is wrong, deadly wrong, to deny any of your fellow Americans the right to vote in this country." The language is deliberately visceral. He wants Congress to feel moral outrage, not merely to weigh policy arguments.
Rhetorical device (repetition): Johnson borrows the phrase "We shall overcome" from the Civil Rights Movement and repeats it throughout the speech. This does two things: it aligns the federal government with the movement, and it builds emotional momentum through sheer repetition.
Central idea: Gender equality is a fundamental right that must be written into the Constitution through the Equal Rights Amendment.
Supporting details:
Chisholm documents systematic discrimination against women in the workplace, schools, and broader society.
She cites unequal pay, limited job options, and societal assumptions about women's roles.
She treats discrimination as a structural problem, not a collection of individual grievances.
Rhetorical appeal (logos): Chisholm presents income data and catalogues legal inequities. Her strategy is to make the case so evidence-heavy that the conclusion feels unavoidable.
Rhetorical device (antithesis): Chisholm writes, "We proclaim equality, yet deny it to half our citizens." By placing the ideal directly against the reality, she exposes the contradiction. The audience does not need to be told what to think; the contrast does the work.
Purpose: Johnson wants Congress to pass voting rights legislation to protect African Americans. Chisholm wants Congress to support the Equal Rights Amendment to protect women. Both address civil rights, but their audiences and legislative targets differ.
Evidence strategies: Johnson leans on moral and historical appeals. Chisholm leans on data and logical reasoning. Neither approach is inherently stronger; each is chosen to match the speaker's purpose and audience.
Rhetorical choices shaped by purpose: Johnson's goal is to unite the country emotionally, so he uses inclusive language and emotional appeals. Chisholm's goal is to dismantle counterarguments, so she builds a logical, evidence-heavy case.
Effectiveness: A reasonable exam answer could argue either speech is more effective, provided the reasoning is clear. The rubric rewards well-justified explanation, not a particular conclusion.
Rhetorical analysis is the same skill set used in law (oral argument), politics (campaign speeches and debate prep), marketing (ad copy), and journalism (detecting spin). When a lawyer structures a closing argument around pathos to win a jury's sympathy, or a company builds a product launch around logos to impress investors, they are making exactly the choices Johnson and Chisholm made. Learning to name those choices is the first step to making, or resisting, them yourself.
Students often confuse a rhetorical appeal with a rhetorical device. An appeal is the broad persuasive strategy (pathos, logos, ethos). A device is a specific technique of language (repetition, antithesis, metaphor). The appeal is the "why"; the device is the "how."
Students sometimes think pathos means the speech is weak or manipulative. Pathos is a legitimate and powerful persuasive strategy; what matters is whether the speaker uses it appropriately for the purpose.
Antithesis is frequently confused with simple comparison. Antithesis requires a deliberate parallel structure that places two opposing ideas in balanced contrast. "She was tall and he was short" is comparison. "We proclaim equality, yet deny it to half our citizens" is antithesis.
Students occasionally identify a rhetorical device without explaining its effect. Naming the device is only half the mark. The rubric explicitly requires you to explain how it develops the central idea.
⚠️ The rubric awards up to 15 points per speech analysis and 20 points for the reflection. The reflection is worth more than either individual analysis.
⚠️ "On Target" (top band) requires the central idea in exactly one sentence, supporting details that connect to that central idea, and both a rhetorical appeal and a rhetorical device with accurate examples and explanations of their effectiveness.
⚠️ The reflection must cover four distinct areas: purpose, evidence/support, how purpose shaped rhetorical choices, and a justified preference for one speech's effectiveness. Missing any one of these drops you out of the top band.
⚠️ You must give a direct quotation (or close paraphrase) from the speech as your example. Vague references like "he uses emotional language" without a specific passage will cost marks.
⚠️ When explaining effectiveness, always link back to the central idea. The question is never just "what device did they use?" but "how does this device serve the argument?"
True or false: Pathos and repetition are both rhetorical appeals. (False. Pathos is an appeal; repetition is a device.)
Fill in the blank: Johnson's speech primarily uses ______ (pathos / logos / ethos) to argue for voting rights. (Pathos.)
True or false: Antithesis requires two opposing ideas presented in a balanced structure. (True.)
Fill in the blank: Chisholm's speech primarily uses ______ (pathos / logos / ethos) to argue for the Equal Rights Amendment. (Logos.)
True or false: The reflection section of the rubric is worth fewer points than each speech analysis. (False. The reflection is worth 20 points; each analysis is worth 15.)
Q: State the central idea of Johnson's "Speech to Congress on Voting Rights" in one sentence.
A: Voting rights are essential to establishing true equality and justice in America.
Q: Identify a rhetorical device Johnson uses and explain how it supports his central idea.
A: Johnson uses repetition, most notably the phrase "We shall overcome." By echoing the language of the Civil Rights Movement, he aligns the federal government's legislative effort with the broader moral struggle, reinforcing his argument that voting rights are a matter of national conscience.
Q: What rhetorical appeal does Chisholm rely on most heavily, and why is it suited to her purpose?
A: Chisholm relies on logos. Because her goal is to demonstrate that gender discrimination is systematic and widespread, presenting income data and legal inequities makes her case difficult to dismiss as merely emotional.
Q: Explain the difference in purpose between Johnson's speech and Chisholm's speech.
A: Johnson seeks to persuade Congress to pass legislation protecting African Americans' voting rights and to frame that legislation as a moral imperative. Chisholm seeks to persuade Congress to support the Equal Rights Amendment by proving that gender discrimination is structural and constitutionally unacceptable.
Q: Give an example of antithesis from Chisholm's speech and explain its effect.
A: Chisholm says, "We proclaim equality, yet deny it to half our citizens." The balanced contrast between the national ideal and the lived reality exposes hypocrisy, making the case for the ERA feel self-evident.
This material connects to any unit on persuasive writing or argumentation, since the same appeal/device framework applies to essays and op-eds. It also ties into American history topics covering the Civil Rights Movement and the women's rights movement, providing primary-source evidence of how political language shaped legislation. If your course covers the other speech pairs (Calhoun/Lincoln on slavery, Nixon/Kennedy debate), the same analytical method applies directly.
