The five canons of rhetoric were first organized by Roman philosopher Cicero in his treatise De Inventione in around 84 BC. Some 150 years later, Roman rhetorician Quintilian explored each of the five canons in more depth as part of his 12-volume textbook entitled Institutio Oratoria. The work helped the five canons become a major component of rhetorical education well into the medieval period. The five canons of rhetoric comprise a system for understanding powerful and effective communication.
Aspect
Description
Introduction
The Five Canons of Rhetoric are a classical framework for the practice of persuasive communication and effective public speaking. Developed by ancient Greek and Roman rhetoricians, these canons provide a structured approach to crafting persuasive speeches and arguments. Understanding these canons is fundamental for students of communication, public speaking, and persuasive writing.
Key Concepts
– Rhetoric: Rhetoric is the art and study of persuasive communication. It encompasses the use of language, argumentation, and delivery to influence and persuade an audience.
– Canons: The term “canon” refers to a fundamental principle or rule. The Five Canons of Rhetoric are the foundational principles that guide the creation and delivery of persuasive messages.
The Five Canons
The Five Canons of Rhetoric are as follows:
– Invention (Inventio): This canon involves the process of developing persuasive arguments and selecting evidence and examples to support one’s case. It requires careful research and consideration of persuasive techniques.
– Arrangement (Dispositio): Arrangement focuses on the organization and structure of a persuasive message. It includes considerations of introduction, body, and conclusion, as well as the logical flow of ideas.
– Style (Elocutio): Style involves the artful use of language and rhetorical devices to make the message compelling and memorable. It includes considerations of tone, diction, and figurative language.
– Memory (Memoria): Memory refers to the practice of memorizing and delivering speeches without written notes. In the classical context, speakers relied on memory techniques to deliver speeches fluently.
– Delivery (Pronuntiatio): Delivery focuses on the physical and vocal aspects of presenting a message. This includes gestures, vocal modulation, eye contact, and overall performance.
How the Model Works
The Five Canons provide a systematic approach to persuasive communication:
– Invention: Speakers or writers research and gather compelling arguments and evidence to support their position.
– Arrangement: They organize their arguments in a logical and persuasive structure, often following a pattern like the classical three-part structure of introduction, body, and conclusion.
– Style: Speakers use language creatively, employing rhetorical devices, vivid imagery, and effective word choice to engage and persuade the audience.
– Memory: While modern speakers often use notes or teleprompters, the practice of memorization was crucial in classical rhetoric.
– Delivery: Speakers pay attention to their physical presence, voice, and gestures to enhance the impact of their message on the audience.
Applications
The Five Canons of Rhetoric have applications in various fields:
– Public Speaking: Public speakers use these canons to craft and deliver persuasive speeches.
– Writing: Writers employ these principles to create compelling essays, articles, and persuasive texts.
– Political Communication: Politicians use rhetorical techniques to persuade voters and gain support.
– Marketing and Advertising: Advertisers employ rhetoric to create persuasive messages and campaigns.
Challenges and Considerations
Challenges in applying the Five Canons include:
– Adaptation to Modern Media: The canons may need adaptation for contemporary communication channels, such as digital media.
– Ethical Considerations: Ethical concerns arise when persuasive techniques are used to manipulate or deceive.
– Cultural Sensitivity: Rhetorical strategies must consider cultural and audience differences.
Future Trends
In modern communication, the Five Canons continue to be relevant, but future trends may involve:
– Digital Rhetoric: The adaptation of classical principles to digital and online communication.
– Visual Rhetoric: The use of visual elements in persuasive communication, particularly in multimedia presentations.
– Neuropersuasion: The study of persuasion from a neuroscience perspective, exploring how messages affect the brain.
– AI-Assisted Rhetoric: The potential role of artificial intelligence in optimizing persuasive messages.
Conclusion
The Five Canons of Rhetoric offer a timeless framework for crafting persuasive messages and delivering them effectively. While modern communication has evolved with digital and multimedia channels, the principles of invention, arrangement, style, memory, and delivery remain foundational in the art of persuasion. Understanding and applying these canons are essential skills for effective communication and public speaking.
A modern interpretation of the concept is perhaps best provided by speech communication professor Gerald M. Phillips:
“The classical canons of rhetoric specify the components of the communication act: inventing and arranging ideas, choosing and delivering clusters of words, and maintaining in memory a storehouse of ideas and repertoire of behaviors… This breakdown is not as facile as it looks. The canons have stood the test of time. They represent a legitimate taxonomy of processes. Instructors [in our own time] can situate their pedagogical strategies in each of the canons.”

Before explaining the five canons in detail, it’s important to first define a canon as simply a tenet of rhetoric.
Although each canon was created in the context of public speaking, most can be applied to the writing and drafting phases of written communication.
The five canons of rhetoric define five general principles, which, when understood and applied, make communication more effective.
Here is a look at each:
Invention (invention)
This is the process of determining the key messages and points that will help convince the audience of a particular point of view.
Cicero defined this process as the “discovery of valid or seemingly valid arguments to render one’s cause probable.”
This requires clarity of purpose and a deep understanding of the subject matter and audience. Equally as important are the presentation style, medium, and length.
Arrangement (disposito)
Or the structure of a speech or text. Ancient models favored an exordium (introduction), narrative, partition (division), confirmation, refutation, and peroration (conclusion).
Modern interpretations are much more simplified, featuring an introduction, body, and conclusion.
Style (elocutio)
Style refers to how something is written or spoken through word choice, sentence structure, and figures of speech.
The goal here is to elicit an emotional response through emotive language and rhetorical strategies including analogy, alliteration, and allusion.
Memory (memorial)
Or any method or device used to improve memory retention.
Roman rhetoricians described two types: the innate ability of natural memory and memory strengthened by particular techniques known as artificial memory.
In ancient times, the fourth canon encouraged orators to memorize a speech in its entirety.
Today, however, this approach is considered too formulaic and may cause a somewhat robotic speaking style.
Memory should instead refer to the orator’s ability to improvise or answer questions on the spot, backed by deep knowledge of the subject matter.
Delivery (pronuntiato)
This encompasses the management of voice and gestures in oral discourse. Delivery may include word emphasis, tone of voice, change of pace, pausing, and use of body language.
Cicero saw delivery as crucial to good oration, defining it as:
“the sole and supreme power in oratory; without it, a speaker of the highest mental capacity can be held in no esteem; while one of moderate abilities, with this qualification, may surpass even those of the highest talent.”

Key takeaways
The five canons of rhetoric comprise a system for understanding powerful and effective communication. They were organized and developed by ancient Romans Cicero and Quintilian.
The five canons of rhetoric represent a legitimate taxonomy of processes that have been effective for thousands of years.
The five canons of rhetoric are invention, arrangement, style, memory, and delivery. Each canon represents a core tenet or principle that can be used in writing and public speaking.
Key Highlights of the Five Canons of Rhetoric:
Invention: This canon involves determining the key messages and arguments to persuade the audience of a particular viewpoint. It focuses on discovering valid or seemingly valid arguments to make one’s case probable. Invention requires a deep understanding of the subject matter, audience, and effective presentation style.
Arrangement: Arrangement refers to the structure of a speech or text. In ancient times, this canon was often organized into stages like introduction, narrative, division, confirmation, refutation, and conclusion. Modern interpretations simplify it to an introduction, body, and conclusion. The arrangement helps create a logical flow that guides the audience through the content.
Style: Style encompasses the way language is used in speaking or writing, including word choice, sentence structure, and rhetorical devices. The goal is to evoke emotional responses and engage the audience through the use of emotive language and strategies like analogy, alliteration, and allusion. Style adds depth and impact to communication.
Memory: Memory involves techniques and devices used to improve memory retention. In ancient times, orators memorized speeches in their entirety, but today, it’s more about having a deep knowledge of the subject matter to improvise effectively. Memory also encompasses the ability to answer questions on the spot, backed by comprehensive understanding.
Delivery: Delivery focuses on the management of voice and gestures during oral communication. It includes elements like word emphasis, tone of voice, pacing, pausing, and body language. Cicero emphasized the importance of delivery, stating that it holds supreme power in oratory. A skilled delivery enhances the impact of the message.
The Aristotle model of communication is a linear model with a focus on public speaking. The Aristotle model of communication was developed by Greek philosopher and orator Aristotle, who proposed the linear model to demonstrate the importance of the speaker and their audience during communication.
The linear model of communication is a relatively simplistic model envisaging a process in which a sender encodes and transmits a message that is received and decoded by a recipient. The linear model of communication suggests communication moves in one direction only. The sender transmits a message to the receiver, but the receiver does not transmit a response or provide feedback to the sender.
Berlo’s SMCR model was created by American communication theorist David Berlo in 1960, who expanded the Shannon-Weaver model of communication into clear and distinct parts. Berlo’s SMCR model is a one-way or linear communication framework based on the Shannon-Weaver communication model.
The helical model of communication is a framework inspired by the three-dimensional spring-like curve of a helix. It argues communication is cyclical, continuous, non-repetitive, accumulative, and influenced by time and experience.
The Lasswell communication model is a linear framework for explaining the communication process through segmentation. Lasswell proposed media propaganda performs three social functions: surveillance, correlation, and transmission. Lasswell believed the media could impact what viewers believed about the information presented.
Modus tollens is a deductive argument form and a rule of inference used to make conclusions of arguments and sets of arguments. Modus tollens argues that if P is true then Q is also true. However, P is false. Therefore Q is also false. Modus tollens as an inference rule dates back to late antiquity where it was taught as part of Aristotelian logic. The first person to describe the rule in detail was Theophrastus, successor to Aristotle in the Peripatetic school.
The five canons of rhetoric were first organized by Roman philosopher Cicero in his treatise De Inventione in around 84 BC. Some 150 years later, Roman rhetorician Quintilian explored each of the five canons in more depth as part of his 12-volume textbook entitled Institutio Oratoria. The work helped the five canons become a major component of rhetorical education well into the medieval period.

A communication strategy framework clarifies how businesses should communicate with their employees, investors, customers, and suppliers. Some of the key elements of an effective communication strategy move around purpose, background, objectives, target audience, messaging, and approach.
Noise is any factor that interferes with or impedes effective communication between a sender and receiver. When noise disrupts the communication process or prevents the transmission of information, it is said to be communication noise.
The 7Cs of communication is a set of guiding principles on effective communication skills in business, moving around seven principles for effective business communication: clear, concise, concrete, correct, complete, coherent, and courteous.
The transactional model of communication describes communication as a two-way, interactive process within social, relational, and cultural contexts. The transactional model of communication is best exemplified by two models. Barnlund’s model describes communication as a complex, multi-layered process where the feedback from the sender becomes the message for the receiver. Dance’s helical model is another example, which suggests communication is continuous, dynamic, evolutionary, and non-linear.
Horizontal communication, often referred to as lateral communication, is communication that occurs between people at the same organizational level. In this context, communication describes any information that is transmitted between individuals, teams, departments, divisions, or units.
Communication apprehension is a measure of the degree of anxiety someone feels in response to real (or anticipated) communication with another person or people.
Closed-loop communication is a simple but effective technique used to avoid misunderstandings during the communication process. Here, the person receiving information repeats it back to the sender to ensure they have understood the message correctly.
Grapevine communication describes informal, unstructured, workplace dialogue between employees and superiors. It was first described in the early 1800s after someone observed that the appearance of telegraph wires strung between transmission poles resembled a grapevine.
The ASE model posits that human behavior can be predicted if one studies the intention behind the behavior. It was created by health communication expert Hein de Vries in 1988.
The ASE model believes intention and behavior are determined by cognitive variables such as attitude, social influence, and self-efficacy. The model also believes that intention predicts behavior such that one’s attitude toward a behavior is influenced by the consequences of that behavior.
Three cognitive variables are the primary determinants of whether the intention to perform a new behavior was sustained: attitude, social influence, and self-efficacy. Various external variables also influence these factors.
Integrated marketing communication (IMC) is an approach used by businesses to coordinate and brand their communication strategies. Integrated marketing communication takes separate marketing functions and combines them into one, interconnected approach with a core brand message that is consistent across various channels. These encompass owned, earned, and paid media. Integrated marketing communication has been used to great effect by companies such as Snapchat, Snickers, and Domino’s.
Social penetration theory was developed by fellow psychologists Dalmas Taylor and Irwin Altman in their 1973 article Social Penetration: The Development of Interpersonal Relationships. Social penetration theory (SPT) posits that as a relationship develops, shallow and non-intimate communication evolves and becomes deeper and more intimate.
The hypodermic needle theory was first proposed by communication theorist Harold Lasswell in his 1927 book Propaganda Technique in the World War. The hypodermic needle theory is a communication model suggesting media messages are inserted into the brains of passive audiences.
The 7-38-55 rule was created by University of California psychology professor Albert Mehrabian and mentioned in his book Silent Messages. The 7-38-55 rule describes the multi-faceted way in which people communicate emotions, claiming that 7% of communication occurred via spoken word, 38% through tone of voice, and the remaining 55% through body language.
Active listening is the process of listening attentively while someone speaks and displaying understanding through verbal and non-verbal techniques. Active listening is a fundamental part of good communication, fostering a positive connection and building trust between individuals.
