12.4: Building Persuasive Power- Appeals, Canons, and Culture

Persuasion Through Different Lenses

More than 2,000 years ago, thinkers like Aristotle and Cicero developed influential ideas about persuasion that continue to shape how public speaking is taught today. Their appeals and canons give speakers practical tools for developing, organizing, and delivering persuasive messages.

But these classical Western traditions are only part of the story. Cultures around the world have developed different ways of thinking about credibility, argument, storytelling, relationships, and the role of the audience. Understanding several rhetorical traditions gives us a broader view of what persuasion can look like.

Aristotle's Three Appeals

More than 2,000 years ago, the Greek philosopher Aristotle argued that effective persuasion depends on balancing three types of appeals: ethos, logos, and pathos (Beebe & Beebe, 2023). While speakers often favor one appeal over the others, the strongest persuasive messages typically combine all three. Audiences want to know that a speaker is credible, that the argument makes sense, and that the issue matters on a human level.

Imagine a student proposing a Student Wellness Initiative that includes food trucks, napping pods, exercise rooms, and meditation spaces. The speaker builds ethos by researching successful programs at other colleges, uses logos by presenting studies linking student well-being to academic success and retention, and appeals to pathos by asking the audience to imagine a campus where students feel less stressed, more connected, and excited to spend time between classes. Together, these appeals make the proposal more persuasive than relying on facts, emotions, or credibility alone.

Ethos: Credibility and Trust

Ethos refers to a speaker's credibility, character, and trustworthiness. Audiences are more likely to listen to speakers they view as knowledgeable, honest, and ethical. Ethos can come from personal experience, expertise, research, preparation, or the way a speaker presents themselves.

Example: A community college student transferring to a UC can strengthen ethos by citing accurate statistics on transfer rates and sharing their own experience navigating the transfer process. In the workplace, a young professional might build ethos by demonstrating expertise while also showing respect for colleagues' perspectives.

Importantly, ethos is not just about credentials. A speaker who appears prepared, fair-minded, and genuine can often build credibility even without formal expertise. Building ethos takes time, but it can be lost quickly if a speaker exaggerates, misrepresents evidence, or appears untrustworthy.

Logos: Logic and Evidence

Logos refers to the use of logic, evidence, and reasoning to support an argument. Speakers use facts, statistics, examples, expert testimony, and cause-and-effect reasoning to help audiences understand why a claim makes sense.

Example: A student arguing for a Student Wellness Initiative might present research showing that exercise improves academic performance, that stress is a major barrier to student success, and that colleges with wellness programs often report higher student satisfaction and retention rates.

Logos is often the foundation of persuasive speaking because audiences are more likely to accept arguments that are supported by clear evidence and sound reasoning. However, facts alone do not always motivate people to change their beliefs or behaviors. Effective speakers help audiences understand not only what the evidence says, but why it matters.

Pathos: Emotion and Human Connection

Pathos refers to appeals that connect with an audience's emotions, values, hopes, fears, and experiences. Emotional appeals help audiences understand why an issue matters and why they should care.

Example: A student advocating for a Student Wellness Initiative might ask listeners to remember a time when they felt overwhelmed, exhausted, or disconnected during a stressful quarter. They might describe students trying to balance classes, work, family responsibilities, and long commutes while struggling to find places on campus to recharge and connect with others.

Pathos is sometimes misunderstood as manipulation, but ethical emotional appeals help audiences connect with the human side of an issue. When used responsibly, pathos can make information more memorable, relatable, and meaningful.

Balancing the Three Appeals

While it can be useful to think of ethos, logos, and pathos separately, effective persuasive speakers often use all three together. A speech with only emotion may feel manipulative. A speech with only facts may feel dry or disconnected. A speech with credibility but little evidence may lack persuasive power.

The most effective persuasive messages answer three audience questions:

• Can I trust you? (Ethos)
• Does your argument make sense? (Logos)
• Why should I care? (Pathos)

When speakers successfully address all three questions, they are more likely to create messages that are credible, compelling, and persuasive. Here's another way of looking at it through when crafting your outline:

• Ethos: Honest, respectful, inclusive language builds credibility.
• Logos: Precise definitions, accurate wording, and clear explanations strengthen logic.
• Pathos: Vivid stories, imagery, metaphors, and emotionally resonant language help audiences care.

Cicero's Five Canons

While Aristotle focused on what makes a message persuasive, the Roman statesman and philosopher Cicero focused on how speakers create and deliver those messages. Cicero's Five Canons of Rhetoric provide a practical framework for developing effective communication, from the earliest stages of brainstorming to the final delivery of a speech (Beebe & Beebe, 2023).

The five canons are invention, arrangement, style, memory, and delivery. Although they were developed more than 2,000 years ago, they remain surprisingly relevant today. Whether you're preparing a class presentation, job interview, social media campaign, TED Talk, or business pitch, the same five steps can help you communicate more effectively.

Invention: Finding Your Ideas

Invention refers to the process of discovering what you want to say. This includes brainstorming topics, researching information, gathering evidence, and identifying the strongest arguments to support your message (Beebe & Beebe, 2023; Lucas, 2024).

Example: A student preparing a transfer application speech might ask, "What challenges did I overcome? What experiences shaped me? What makes my story unique?" A professional pitching a new project might focus on identifying a problem and explaining how their proposal provides a solution.

Strong invention requires curiosity and critical thinking. Before worrying about slides or delivery, speakers should focus on developing meaningful ideas and finding evidence that supports their message.

Arrangement: Organizing Your Message

Once you have ideas, you need to organize them in a way that audiences can easily follow. Arrangement refers to the structure of a speech and how information is sequenced.

Example: A student advocating for more internship opportunities might organize their speech using a Problem-Cause-Solution pattern. An environmental activist might begin by explaining a problem, identify contributing causes, and conclude with possible solutions.

Good arrangement helps audiences stay engaged and prevents them from feeling lost. Even strong ideas can become ineffective if they are presented in a confusing or disorganized way (Lucas, 2024; Duarte, 2012).

Style: Choosing Your Words

Style refers to the language, tone, and wording a speaker uses to communicate their message. Effective speakers adapt their style to fit their audience, purpose, and occasion.

Example: A student encouraging classmates to apply for scholarships might say, "Don't let money decide your future. Let your potential decide it." The speaker uses simple, encouraging language and repetition to create a message that is both memorable and motivating. A healthcare professional discussing the dangers of vaping might instead choose clear, factual language and relatable analogies to explain long-term health risks.

Style is not about using complicated vocabulary or sounding impressive. Often, the most effective communicators use clear, simple language that helps audiences understand and remember their message.

Effective style also means choosing language that is clear, vivid, and audience-centered. Strong speakers avoid unnecessary jargon, define unfamiliar terms, and use concrete language that helps listeners visualize ideas. They may also use rhetorical devices such as repetition, parallelism, metaphors, analogies, or rhetorical questions to make key points more memorable. The goal is not to sound sophisticated, but to make your ideas easier to understand, remember, and act upon (Lucas, 2024; Beebe & Beebe, 2023).

Memory: Knowing Your Material

Memory refers to a speaker's familiarity with their content. Historically, speakers memorized entire speeches. Today, memory is less about reciting every word and more about understanding your material well enough to speak confidently and adapt when needed.

Example: A student participating in a classroom debate who understands their evidence and key arguments can respond to questions more effectively than someone who has memorized a script. In the workplace, a manager who knows a proposal thoroughly can answer questions and handle challenges with confidence.

Many beginning speakers focus on memorizing sentences. More experienced speakers focus on mastering ideas (Lucas, 2024).

Delivery: Bringing the Message to Life

Delivery refers to how a message is presented through voice, eye contact, facial expressions, gestures, movement, and overall presence. Delivery influences whether audiences perceive a speaker as confident, credible, and engaging (Beebe, 1974; Beebe & Beebe, 2023).

Example: A student interviewing for a scholarship might use strong eye contact, vocal variety, and confident posture to make a positive impression. In public life, leaders, activists, and content creators often gain influence not only because of what they say, but because of how they say it.

Think about influential speakers, TED presenters, YouTubers, or podcast hosts. Their success often depends as much on delivery as on content.

Putting the Canons Together

The Five Canons work together as a process:

• Invention helps you decide what to say.
• Arrangement helps you organize it.
• Style helps you choose how to say it.
• Memory helps you know it.
• Delivery helps you present it.

For example, a student proposing food trucks, napping pods, and meditation spaces on campus might first research student wellness needs (invention), organize their speech using Monroe's Motivated Sequence (arrangement), choose language that is positive and student-centered (style), practice until they know their material well (memory), and deliver the speech with confidence and enthusiasm (delivery).

Although communication technologies have changed dramatically since Cicero's time, the basic challenge remains the same: developing a message that audiences will understand, remember, and act upon.

Putting It All Together

Aristotle’s appeals and Cicero’s canons give us practical tools for creating persuasive messages. The appeals help us think about credibility, reasoning, and emotion, while the canons help us develop, organize, practice, and deliver those ideas effectively.

Table 11.4.1 shows how these classical concepts can work together in college, workplace, and global contexts. But effective persuasion also depends on something these models alone cannot fully explain: culture and context. What sounds credible, logical, emotional, or appropriate can vary across audiences and communities.

To understand persuasion more fully, we need to look beyond the classical Western tradition and consider how other rhetorical traditions approach communication.

Persuasion Across Cultures and Traditions

Aristotle’s ideas about ethos, pathos, and logos have had a major influence on how public speaking is taught in the United States. But they represent one rhetorical tradition, not the only way people have understood effective communication. Comparative rhetoric broadens our understanding of persuasion by examining rhetorical traditions across cultures rather than treating Western approaches as universal (Mao, 2014).

Different cultures and historical traditions have developed their own ideas about what makes a speaker credible, what audiences value, and how people should handle disagreement. Some Western traditions emphasize individual argument, direct claims, evidence, and debate. Other traditions may place greater emphasis on relationships, community, harmony, storytelling, listening, or indirect communication. Contemporary intercultural rhetoric also cautions against treating cultures as fixed categories. Communication changes depending on the people involved, their communities, the situation, and the larger social context (McIntosh et al., 2022).

For example, Confucian rhetorical traditions emphasize relationships, ethical character, respect, and social harmony. A speaker’s credibility may depend as much on how they fulfill their responsibilities to others as on how effectively they argue a position. Indigenous rhetorical traditions often emphasize storytelling, collective knowledge and memory, relationships to community and place, and knowledge passed between generations (Gross, 2021). African and African American rhetorical traditions have also drawn upon storytelling, rhythm, repetition, audience participation, and call-and-response, making the audience an active participant in communication rather than simply a group receiving a message (Browdy & Milu, 2022).

These traditions remind us that there is no single formula for effective persuasion. Even concepts such as credibility, logic, and emotional appeal can look different across cultures and communities. A speech that sounds confident and persuasive to one audience might sound aggressive, disrespectful, or overly individualistic to another. Effective speakers consider not only what they want to say, but also the cultural experiences, expectations, and values their audiences may bring to the interaction.

Studying rhetoric across cultures also gives us another tool for critically examining public discourse. When analyzing a historical speech, political debate, protest movement, social media campaign, or contemporary controversy, don’t just ask, “Was it persuasive?” Ask: Who was speaking? Who had the power to speak? Whose voices were missing? What cultural values shaped the message? What did the speaker want the audience to believe or do?

Critical analysis means looking beyond whether we agree with a message and examining how persuasion works, whose interests it serves, and what consequences it may have.

Key Takeaways

• Ethos, logos, and pathos are the three primary persuasive appeals. Effective speakers build credibility (ethos), support claims with logic and evidence (logos), and connect to audience values and emotions (pathos).
• The Five Canons of Rhetoric provide a framework for creating effective messages. Invention, arrangement, style (effective language choices), memory, and guide speakers from developing an idea to delivering it effectively.
• Persuasion is shaped by culture, context, and audience. Studying different rhetorical traditions helps us understand how persuasion works and critically evaluate the messages we encounter.

Exercises 

• Appeals Swap: One student makes a quick persuasive claim using ethos, and the partner rewrites it using logos or pathos. 
• Delivery Challenge: Each partner delivers the same short pitch twice (once with flat delivery and once with strong eye contact and vocal variety), then give feedback.
• Personal Story Connection: Think of a personal experience that could connect to a larger issue (Example: missing a bus leading to a bigger point about public transit) and write two sentences linking the story to the issue.
