1.3 Overview of major rhetorical concepts and their evolution
6 min read•Last Updated on July 30, 2024
Greek rhetoric laid the foundation for persuasive communication. The modes of persuasion—ethos, pathos, and logos—form the core of effective arguments. These concepts, along with kairos and stasis theory, help speakers craft compelling messages.
The rhetorical canons—invention, arrangement, style, memory, and delivery—offer a structured approach to creating and presenting arguments. These principles, developed in ancient Greece, continue to shape modern communication strategies across various media and contexts.

Ethos refers to the character and credibility of the speaker or writer
Established through demonstrating expertise, moral character, and goodwill towards the audience
Examples of establishing ethos include citing relevant qualifications, sharing personal experiences, and acknowledging the audience's concerns (Martin Luther King Jr.'s "I Have a Dream" speech)
Effective use of ethos builds trust and rapport with the audience
Pathos: Appealing to Emotions
Pathos involves appealing to the emotions of the audience to evoke a desired response
Evokes emotions such as empathy, anger, fear, or hope to persuade the audience
Examples of pathos include vivid storytelling, powerful imagery, and emotive language (ASPCA commercials featuring neglected animals)
Effective use of pathos engages the audience on an emotional level and motivates them to take action
Logos: Logical Reasoning and Evidence
Logos focuses on the use of logical reasoning, evidence, and arguments to persuade the audience
Supports the speaker's claims through facts, statistics, examples, and expert testimony
Examples of logos include citing scientific studies, presenting historical data, and using syllogisms (Aristotle's "All men are mortal" syllogism)
Effective use of logos appeals to the audience's sense of reason and strengthens the credibility of the argument
Applying Modes of Persuasion in Context
The effective use of ethos, pathos, and logos depends on the rhetorical situation
Factors to consider include the audience, purpose, and context of the communication
Aristotle's treatise "On Rhetoric" provides the foundational framework for understanding and applying these modes of persuasion in various contexts
Examples of effective combination of ethos, pathos, and logos include political speeches, advertising campaigns, and legal arguments (Cicero's defense speeches)
Kairos in Rhetorical Practice
Understanding Kairos as Opportune Timing
Kairos refers to the opportune moment or appropriate timing for delivering a persuasive message
Aims to achieve maximum impact by considering the specific circumstances, audience, and context
Examples of kairos include delivering a sales pitch when a customer is most receptive or addressing a crisis at its peak urgency (Winston Churchill's "We shall fight on the beaches" speech during World War II)
Effective use of kairos requires speakers to be attuned to the unique demands and opportunities of each rhetorical situation
Adapting Rhetorical Strategies to the Situation
The concept of kairos emphasizes the importance of adapting one's rhetorical strategies to the specific circumstances
Factors to consider include the audience's receptiveness, the urgency of the issue, and the broader social and political climate
Examples of adapting to kairos include tailoring a message to a specific cultural context or adjusting the tone of an argument based on recent events (President Obama's address after the Sandy Hook shooting)
In ancient Greek rhetoric, kairos was considered a key principle for successful oratory
Kairos in Contemporary Rhetorical Practice
The concept of kairos has evolved over time, with modern interpretations emphasizing its relevance to various forms of communication
Applies to digital media, such as social media campaigns and viral marketing, where timing and relevance are crucial
Examples of kairos in contemporary contexts include responding to a public relations crisis or launching a product at the optimal market moment (Apple's iPhone releases)
Kairos also plays a role in intercultural communication, where understanding cultural norms and expectations is essential for effective persuasion
Stasis Theory for Argument Structure
Identifying Points of Disagreement
Stasis theory provides a framework for identifying and addressing the key points of disagreement or controversy in a rhetorical situation
Helps rhetors focus their efforts on the most relevant and persuasive aspects of the issue at hand
Examples of applying stasis theory include identifying whether a debate centers on facts, definitions, values, or actions (The stasis of definition in the debate over what constitutes "fake news")
By determining the appropriate stasis, speakers can clarify their position and anticipate counterarguments
The Four Primary Stases
The four primary stases, as outlined by ancient Greek rhetoricians, are:
Conjecture (questions of fact)
Definition (questions of meaning)
Quality (questions of value or significance)
Policy (questions of action or procedure)
Examples of each stasis include:
Conjecture: Did the accused commit the crime?
Definition: What constitutes a "hate crime"?
Quality: Is the proposed policy beneficial or harmful?
Policy: What steps should be taken to address climate change?
Understanding the stases helps rhetors structure their arguments effectively and respond to opposing viewpoints
Stasis Theory in Different Rhetorical Contexts
The application of stasis theory can vary depending on the rhetorical genre and context
In deliberative rhetoric, such as political speeches, stasis theory helps identify the key issues and propose solutions
In epideictic rhetoric, such as funeral orations, stasis theory focuses on the praise or blame of the subject
In forensic rhetoric, such as legal arguments, stasis theory is used to establish the facts and determine guilt or innocence
Contemporary scholars have expanded upon the classical understanding of stasis theory, exploring its implications for argumentation in fields such as law, politics, and science (The use of stasis theory in environmental policy debates)
Development of Rhetorical Canons
The Five Rhetorical Canons
The five rhetorical canons, as codified by ancient Greek and Roman rhetoricians, are:
Invention (discovering arguments)
Arrangement (organizing arguments)
Style (selecting appropriate language)
Memory (retaining and delivering speeches)
Delivery (presenting speeches effectively)
These canons provide a comprehensive framework for the art of persuasive communication
Examples of applying the canons include developing arguments using topoi and stasis theory (invention), organizing a speech using the parts of an oration (arrangement), and employing rhetorical devices and figures of speech (style)
Invention, Arrangement, and Style in Greek Oratory
The canon of invention involves the process of finding and developing persuasive arguments
Draws upon topics (topoi) and lines of reasoning (stasis) relevant to the rhetorical situation
Arrangement focuses on the effective organization and structure of a speech
Typically follows the parts of an oration: introduction (exordium), statement of facts (narratio), division (partitio), proof (confirmatio), refutation (refutatio), and conclusion (peroratio)
The canon of style emphasizes the importance of selecting appropriate language, figures of speech, and rhetorical devices to enhance the persuasive impact of the message
Examples of effective use of invention, arrangement, and style can be found in the speeches of Greek orators such as Demosthenes and Isocrates
Memory and Delivery in Ancient Oratory
Memory, in the context of ancient oratory, refers to the techniques used by speakers to memorize and deliver their speeches without relying on written notes
The method of loci (memory palace) was a popular mnemonic device used by orators to associate parts of their speech with familiar locations
Delivery involves the effective use of voice, gesture, and physical presence to convey the message and engage the audience during the presentation of the speech
Ancient Greek orators, such as Demosthenes, were known for their powerful delivery and ability to captivate audiences
The rhetorical canons were central to the education and practice of Greek orators, who exemplified the art of persuasive speaking in political, legal, and ceremonial contexts
Adapting Rhetorical Canons to Contemporary Communication
While the canons were initially developed for oral rhetoric, their principles have been adapted and applied to various forms of written and visual communication throughout history
Examples of applying rhetorical canons to contemporary contexts include using invention strategies in essay writing, arranging arguments in a persuasive blog post, and employing stylistic devices in a political campaign speech
The canons continue to provide a valuable framework for analyzing and creating effective persuasive messages across various media and genres
