Aristotle's Rhetorical Triad - Comprehensive Notes
The Big Question: What is rhetoric?
Rhetoric is the study and uses of written, spoken, and visual language. It investigates how language is used to organize and maintain social groups, construct meanings and identities, coordinate behavior, mediate power, produce change, and create knowledge. In short, rhetoric helps explain how language shapes social life and knowledge, not just what people say.
A concise working definition from Aristotle: rhetoric is the art of discerning in any given situation the available means of persuasion. This emphasizes not just words, but the methods and tools used to influence others.
In this course, rhetoric is framed as about how people say and do things to affect others—how persuasion is orchestrated through language and action.

Aristotle: who he was and why he matters
Aristotle was an ancient Greek philosopher, a student of Plato, and a teacher of Alexander the Great. He is a foundational figure in Western philosophy and science, writing extensively on ethics, aesthetics, logic, science, politics, metaphysics, biology, linguistics, and more.
He produced a comprehensive system of thought, including works on rhetoric. One notable book about drama is Poetics; he also wrote about rhetoric and the art of persuasive speaking.
The lecture mentions a humorous aside about statues: a reminder that societies sometimes place clothing on statues, which the speaker finds odd, but it’s a digression from core ideas.
Significance: Aristotle’s ideas about rhetoric underpin the triad we study today and anchor long-standing ways of analyzing how persuasion works in speech and writing.
The Rhetorical Triangle (Aristotle’s triad)
Rhetoric requires three elements: a speaker (the rhetor), a subject/text (what’s being said), and an audience. These three components form what’s called the rhetorical triangle or triad.
Key terminology: the speaker is also called the rhetor, the subject is the text, and the audience is the readers or listeners. The speaker and rhetor are interchangeable terms in this discussion; the same for subject/text.
Important dynamic: the arrows between the three points go both ways, illustrating interdependence. How the speaker relates to the subject and audience, how the subject relates to the speaker and audience, and how the audience relates to the speaker and subject all influence persuasive effectiveness.
Context and purpose are included as part of the surrounding situation. Texts are produced within a context and for a purpose; they do not exist in a vacuum.
The audience is described as an active recipient who interacts with the text and the speaker. The speaker must consider the audience’s expectations, prior knowledge, opinions, and potential biases. Past experiences with audiences and previous presentations shape how one approaches new audiences.
The rhetor’s persona (the writer’s voice or character) is a critical aspect of how the speaker is conveyed. Aristotle’s term for this is persona—the character the speaker creates as they write or speak. Voice, tone, and style are chosen to fit the subject and audience.
Context and purpose significantly affect how rhetoric works. The same topic can be framed differently depending on when and where a speech is delivered and what the speech aims to accomplish (heal, provoke, inform, persuade, etc.).
In short, the triad is a dynamic system: the speaker (rhetor) speaks about a subject to an audience within a context and for a purpose, with the speaker’s persona shaping how the message is delivered.
Relationships within the triangle: subject/text, audience, and speaker
Subject/text relationship: Before creating, the rhetor evaluates what they already know, what they need to know, and what perspectives to consider. They decide the types of evidence that will be most useful and how to approach the subject. This evaluation shapes the persuasive strategy.
Audience relationship: The rhetor anticipates what the audience expects, what the audience knows, and what opinions they might hold. The audience’s preconceived notions, biases, and experiences influence how the message should be crafted.
Speaker relationship (rhetor/persona): The rhetor’s own identity, knowledge, feelings, and experiences influence how they approach the subject and audience. This enables choices about language, style, and tone. The speaker’s persona is the character projected to the audience.
Interdependence: All three elements are interconnected and mutually influential. The success of persuasion depends on how well the speaker aligns subject knowledge, audience expectations, and the speaker’s persona within the given context and purpose.
The slide emphasizes that this interdependence is a core feature of Aristotle’s triad, hence the triangle imagery.
Context and purpose: The situation surrounding the speech (the context) and the intended outcome (the purpose) strongly shape how the triangle operates. For example, a three-week-old speech on racism would be very different from a speech delivered after the Charlottesville events in August 2017. Texts do not exist without their environment, and that environment changes how audiences receive them.
The three appeals: logos, ethos, pathos
Aristotle’s appeals are tools rhetorists use to connect with the audience and maximize the effectiveness of the rhetorical relationships. The three appeals are:
Logos: an appeal to reason, logic, and facts. This involves making clear, reasoned claims supported by evidence and details so the audience can follow the argument and see the logical progression.
Ethos: an appeal to authority, credibility, or character. It involves demonstrating that the speaker is credible, well-intentioned, and knowledgeable about the subject, and aligning with the audience’s moral or ethical beliefs. Quintilian’s famous point is that the speaker should be a good person speaking well (translated as “the good man speaking well”).
Pathos: an appeal to emotion, feeling, or affect. It involves engaging the audience’s emotions—fear, love, anger, hope, etc.—to motivate action or agreement. Pathos is noted as the most powerful and frequently used appeal because emotions can prompt quick responses and can shortcut purely logical processing.
Practical notes on the appeals:
In practice, appeals often overlap. A single argument can simultaneously feature logos, ethos, and pathos. Rhetorical statements can demonstrate logos through logical structure, ethos through speaker credibility, and pathos through emotionally charged language.
The overlap is why analyzing rhetoric can be nuanced and interpretive: even a single adjective or phrase can add an emotional or ethical dimension to a logical claim.
Real-world relevance: Logos tends to be favored in scholarly or technical contexts; ethos matters in credibility-conscious settings; pathos dominates in advertising and political messaging due to its quick, emotional impact.
Ethical, philosophical, and practical implications of Aristotle’s framework
Ethical considerations: The ethos appeal highlights the importance of a speaker’s character and credibility, echoing Quintilian’s maxim. This raises questions about manipulation, trust, and responsibility in persuasion.
Practical considerations: Pathos can be very effective but risks manipulating audiences if used irresponsibly. Logos provides rational grounding, but without ethos and pathos, arguments can be dry or fail to resonate emotionally.
Philosophical implications: The triad shows that persuasion is not purely about logic; it’s about human beings in social contexts with beliefs, values, and emotions. The framework emphasizes responsibility in how arguments are constructed and presented.
Summary and study-oriented takeaways
Rhetoric is the study and use of written, spoken, and visual language to organize, change, and understand social life and knowledge. The core functional definition is: rhetoric is the art of discerning in any given situation the available means of persuasion.
Aristotle’s rhetorical triangle consists of three interdependent components: the speaker (rhetor), the subject/text, and the audience. These elements relate bidirectionally and are embedded in context and purpose.
The relationships within the triangle are shaped by what the rhetor knows, what they need to know, anticipated audience expectations, the rhetor’s persona, and the surrounding context. The audience participates as receivers of the message and as evaluators of credibility and emotional appeal.
The three appeals—logos, ethos, and pathos—provide methods for persuading: reasoning and evidence (logos), credibility and character (ethos), and emotion (pathos). They are not mutually exclusive and often operate together.
The framework is foundational for rhetorical analysis and helps explain how texts are created, interpreted, and evaluated in real-world situations. It also invites ongoing questions about ethical persuasion and the dynamic relationship between language, power, and society.
Note: The lecture reinforces that this is the starting point for a year-long focus on rhetorical analysis and how to read texts critically using Aristotle’s triad.
