11.2 Rhetorical Appeals and Stylistic Devices

Rhetorical Appeals and Stylistic Devices

Quick Answer: Persuasive nonfiction relies on three classical appeals: ethos (credibility of the speaker), pathos (appeal to emotion), and logos (appeal to logic and evidence). Writers deliver these appeals through recognizable stylistic devices, including the rhetorical question (posed to guide thought rather than solicit an answer), antithesis (contrasting ideas in balanced structure), parallelism and anaphora (repeated grammatical structure or repeated opening words, building rhythm and emphasis), and allusion (a reference to an outside person, event, or text whose associations the writer imports into the argument). On the CLEP exam, correctly naming a device earns nothing by itself; every question rewards connecting the device to the specific effect it produces in that exact passage.

The Three Classical Appeals

Aristotle's framework for persuasion identifies three distinct ways a writer or speaker can move an audience, and nearly every persuasive nonfiction passage on the exam leans on some combination of the three.

Ethos is an appeal built on the credibility, authority, or trustworthiness of the speaker. A writer establishes ethos by citing relevant credentials or direct experience, demonstrating fairness by acknowledging opposing views, or using a measured, careful tone that signals reliability. Ethos answers the implicit audience question, "why should I trust this person's judgment on this subject?"

Pathos is an appeal to the audience's emotions, fear, hope, anger, sympathy, pride, and it works by making an issue feel personally urgent or morally weighted rather than abstract. A writer builds pathos through vivid anecdote, emotionally charged diction, direct address, or a scenario the reader can imagine happening to someone they care about.

Logos is an appeal to logic, evidence, and reasoned argument, built from statistics, cause-and-effect chains, expert testimony treated as evidence rather than as a credibility marker, and structured claims supported by verifiable premises. Logos answers the implicit question, "does this conclusion actually follow from the evidence presented?"

Original example, the same argument delivered through three appeals:

Ethos: As a public health nurse who has staffed vaccination clinics for two decades, I have watched preventable outbreaks return the moment vaccination rates dip below the threshold doctors rely on.

Pathos: Picture a nursery of six-week-old infants too young to be vaccinated themselves, entirely dependent on the immunity of the adults walking past their cribs.

Logos: When regional vaccination coverage fell from 95 percent to 88 percent over three years, reported measles cases in that same region rose from two to forty-one, a pattern consistent with the threshold epidemiologists call herd immunity.

All three sentences argue for the same underlying position, but the first relies on the speaker's stated experience (ethos), the second on an emotionally vivid, imagined scene (pathos), and the third on numerical evidence and a named causal pattern (logos). A CLEP question asking which appeal a given sentence relies on most is testing whether you can isolate which of these three mechanisms, credibility, emotion, or evidence, is actually doing the persuasive work in that specific sentence, rather than the passage as a whole.

The Rhetorical Question

A rhetorical question is posed without any expectation of a literal spoken or written answer; instead, it steers the reader toward a conclusion the writer wants them to reach independently, or it emphasizes a point so obvious, or so urgent, that an actual answer feels unnecessary.

Original example:

How many more warnings do we need before we admit the bridge is no longer safe to cross?

The writer is not soliciting a numerical answer; the question implies that the correct answer is "none" and that the audience already agrees, using the question's form to make that shared conclusion feel self-evident rather than argued for directly.

Antithesis: Contrast in Balanced Form

Antithesis places two sharply contrasting ideas within a single, grammatically balanced structure, and the parallel form intensifies the contrast between the two ideas by presenting them as mirror images of each other.

Original example:

We asked for bread and were handed a speech; we asked for shelter and were handed a survey.

Each half of the sentence mirrors the other's grammatical structure ("we asked for X and were handed Y"), and that mirrored balance sharpens the contrast between what was requested and what was actually delivered, making the gap between need and response feel more pointed than an unbalanced sentence would.

Parallelism and Anaphora in Nonfiction Argument

Parallelism, repeating a grammatical structure across a sentence or series of clauses, builds rhythm and signals that the repeated items carry equivalent weight. Anaphora is a specific, frequently tested form of parallelism: the repetition of the same word or phrase at the beginning of successive clauses or sentences, which builds cumulative emphasis through insistence.

Original example of anaphora:

We will not accept another delay. We will not accept another excuse. We will not accept another year of waiting.

The repeated opening phrase, "we will not accept," accumulates force across three successive clauses, and the escalating specificity of what follows each repetition (delay, excuse, a full year) intensifies the sense of mounting resolve, an effect a single unrepeated sentence stating the same claim once could not achieve.

Allusion: Borrowing Outside Associations

An allusion is a brief reference to a person, historical event, literary work, or cultural touchstone outside the passage itself, and its persuasive or emotional power depends entirely on the reader recognizing the reference and importing the associations it carries into the current argument. An allusion works efficiently, in a few words, because it borrows the full weight of an already-familiar story rather than building that weight from scratch.

Original example:

Every administration that has ignored a warning this specific has eventually found its own Pompeii.

A reader who recognizes the allusion to Pompeii, a city destroyed by a volcanic eruption after warning signs were reportedly dismissed, imports that association (ignored warnings followed by total, sudden catastrophe) directly into the writer's argument, achieving in five words a comparison that would otherwise require several sentences of explicit explanation. If a reader does not recognize the allusion, the sentence loses most of its persuasive force, which is why allusions work best when a writer can reasonably assume shared cultural or historical knowledge with the intended audience.

Exam Application: Naming the Device Is Not Enough

CLEP questions on rhetorical appeals and devices never award credit for correctly labeling a device in isolation; every correct answer connects the device's specific mechanics in that sentence to the effect it produces. When a question presents a sentence and asks about its rhetorical strategy, work through three checks. First, decide which of the three classical appeals, ethos, pathos, or logos, the sentence is most clearly built on, by asking whether it leans on the speaker's credibility, the reader's emotion, or presented evidence and reasoning. Second, check whether a specific stylistic device, rhetorical question, antithesis, anaphora, or allusion, is doing the delivering, and be ready to explain what that device's particular mechanism (mirrored contrast, repeated opening, borrowed outside association) contributes that a plain declarative sentence would not. Third, when answer choices offer a device that is technically present but only marginally responsible for the sentence's actual effect, favor the option that names both the dominant device and its precise, textually supported effect over an option that names a real device doing only minor work in that sentence.
